From e0fa631d4980a427e2365603da8f7ca095c7dc89 Mon Sep 17 00:00:00 2001 From: Eric Mann Date: Thu, 24 Sep 2026 13:24:18 -0700 Subject: [PATCH 01/56] Add the Foundry spec for this flight docs/SPEC.md wraps examples/vault-provider/SPEC.md in the shape the Foundry planner reads, adding the repository's documentation, journal, and no-publish rules. docs/foundry.json is pre-seeded with the verify commands and auto permission mode for an unattended run. --- docs/SPEC.md | 125 ++++++++++++++++++++++++++++++++++++++++++++++ docs/foundry.json | 15 ++++++ 2 files changed, 140 insertions(+) create mode 100644 docs/SPEC.md create mode 100644 docs/foundry.json diff --git a/docs/SPEC.md b/docs/SPEC.md new file mode 100644 index 0000000..77d2b70 --- /dev/null +++ b/docs/SPEC.md @@ -0,0 +1,125 @@ +# HashiCorp Vault KV v2 provider example — Specification + +Version: 1.0 +Status: ready + +This is the Foundry wrapper for this flight. **The design lives in `examples/vault-provider/SPEC.md`.** Read it in full. +It is authoritative for every behaviour, file name, and test it names. Where it and this file +disagree on process, this file wins. Where they disagree on design, `examples/vault-provider/SPEC.md` wins. + +Background, read before planning: `docs/decisions/0008-the-trac-ticket-replaces-thread-confirmation.md`, +`docs/decisions/0007-fail-closed-on-a-broken-drop-in.md`, `docs/spec/providers-and-keyrings.md`, +`docs/spec/extension-points.md`, `docs/journal/test-coverage-gaps.md`, and +`docs/journal/2026-09-04-0-1-0-is-public.md` (the voice for the journal entry). + +## 1. Overview + +Build the HashiCorp Vault KV v2 provider example described in the detailed spec. It is the first backend whose versioning does not match the two-slot model, so the four questions in the detailed spec each need a written answer. Also fix site-scope naming in the AWS Secrets Manager example, as its own commit. + +Done means the detailed spec's "Done when" section is met, except for the steps it marks as +human or live-cloud, which are left as `Manual check: NOT VERIFIED (human)`. The branch must also +carry the documentation and journal entry described in §2. + +## 2. Goals and non-goals + +- Goal: every deliverable in `examples/vault-provider/SPEC.md`, with tests written in the same task as the code. +- Goal: the documentation matches the code. Update every page under `docs/` whose statements + this work changes: spec pages ("As built" and "Why"), the journal tracking pages + (`open-questions.md`, `test-coverage-gaps.md`, `proposal-questions.md`), `examples/README.md`, + `README.md`, and `docs/index.md` for any new page. Regenerate `docs/reference/` whenever a + docblock changes. +- Goal: **one dev journal entry** for this piece of work, at + `docs/journal/YYYY-MM-DD-a-vault-provider.md`, dated the day it is written, with frontmatter + `title`, `description`, and `date`. Write it in the voice of + `docs/journal/2026-09-04-0-1-0-is-public.md`: first person, plain, specific. Cover what was + built, what it found (especially anything that changed `src/` or an interface), what was + deliberately left out, and what it means for the Trac patch. Link to the example or test and to + ADR 0008. Do not use the `/journal-entry` skill, because it reads and clears the shared + `_drafts/notes.md`. +- Non-goal: anything the detailed spec lists as out of scope. +- Non-goal: the Trac patch itself, a release, a tag, or publishing the docs site. + +## 3. Engineering principles + +- **Read first.** Before any task, read `CONTRIBUTING.md` and the "Working in this repository" section of `CLAUDE.md`. Both bind every task. +- **Keep the existing `CLAUDE.md` content.** When the plan stage writes `CLAUDE.md`, keep the current `# Working in this repository` section verbatim at the top and add the Foundry headings below it. Removing or rewording that section is a review failure. +- **`src/` is copy-ready for core.** Use core's coding standard, the `default` text domain, and `@since 7.2.0`, with no `function_exists()` guards. `tests/phpunit/test-architecture.php` enforces this. `plugin/` and `cli/` are never copied into core. +- **Errors, not exceptions.** Public API functions return `WP_Error` (or `false`) and never throw. A caller error is `_doing_it_wrong()` plus `WP_Error( WP_SECRETS_ERROR_INVALID_ARGUMENT )`. +- **No plaintext in output.** A plaintext secret or raw key material never appears in a log line, a `WP_Error` message, CLI output (except `get --reveal`), a test failure message, or a persistent cache. The reviewer checks this by reading. +- **Tests only get stronger.** Never delete or weaken an existing test. Never skip a test except for an environment gate, such as multisite-only. Every `phpcs:ignore` and every new `phpcs.xml.dist` exclusion carries a reason on the same line. +- **Generated reference.** `docs/reference/` is generated. When a docblock changes, run `make reference` and commit the result in the same task. `make reference-check` must pass. +- **Spec pages** under `docs/spec/` keep exactly three sections, in this order: **As proposed**, **As built**, **Why**. A behaviour change updates "As built", and "Why" if the code now departs from the proposal. +- **ADRs.** A new design decision gets an ADR under `docs/decisions/`, numbered `NNNN-slug.md` after the highest existing number, with number, title, date, status, context, decision, and consequences, in the existing ADRs' style. Two other flights may also add ADRs, so pick the next number and expect it to be renumbered at merge. +- **Nothing private in `docs/`.** Never mention employers, customers, or internal channels there. +- **Never publish.** Never run `sf publish`, never create or push a tag, and never touch Spacefast settings. Publishing happens after merge, by a human. +- **Commit style.** Commit messages follow `git log`: an imperative title, then a body explaining why, wrapped at 72 columns. Foundry's `: ` title prefix is fine. +- **Examples are single files.** Each example under `examples/` is a single-file drop-in with no Composer and no SDK, and stays excluded from `make ci`'s lint. It is written to be read from top to bottom. +- **Parallel flights.** Two other branches are being built from the same `main` at the same time: `build/kms-keyring` (the KMS keyring example, root-key caching, `rotate --from`, and the shared examples test harness) and `build/cli-smoke` (the WP-CLI smoke test). Do not do their work. Keep edits to shared files (`Makefile`, `.github/workflows/ci.yml`, `examples/README.md`, the `docs/journal/*.md` tracking pages, `docs/index.md`) additive and confined to your own section or entry, to make the merge easy. + +## 4. Architecture + +- `src/wp-includes/`: the API as it will ship in core. Change it only where the detailed spec + says to. +- `plugin/`: the plugin-only upgrade path from the prototype. Do not touch it. +- `cli/`: the WP-CLI commands, which are plugin-only. +- `tests/phpunit/` and `tests/includes/`: the PHPUnit suite and its shared base classes, mocks, + and conformance suites. +- `examples//`: single-file platform drop-ins, plus their own `README.md` and `tests/`. +- `docs/`: the published documentation site's source (`site/` only renders it). +- `bin/`: developer and CI scripts. + +## 5. Data and configuration + +Every configuration constant and default is named in `examples/vault-provider/SPEC.md`. There are no tunables to invent. +If a timeout or limit is not given there, mark it `⚠️ ASSUMPTION`, give it a named constant in the +example file, and justify it in a comment. + +## 6. Interfaces + +`WP_Secrets_Provider`, `WP_Secrets_Keyring`, and `WP_Secrets_Store` in `src/wp-includes/`. The +provider contract is also documented in `docs/spec/extension-points.md`. The conformance suite +lives in `tests/includes/class-wp-secrets-provider-conformance.php`. Do not change an interface's +method signatures. A docblock clarification is allowed where the detailed spec calls for one. + +## 7. Commands + +- Full verification: `bin/ci-local.sh --keep`, which runs lint, compat, phpstan, and the + single-site and multisite PHPUnit suites inside this worktree's own wp-env. Give it a 30-minute + timeout. Then `make reference-check`. +- This worktree's wp-env ports are 8920 and 8921, set in the git-ignored + `.wp-env.override.json`, which already exists. Never edit or commit it. Never run + `wp-env destroy`. +- Run a single test file fast with + `npx @wordpress/env run --env-cwd=wp-content/plugins/vault-provider tests-cli vendor/bin/phpunit `. +- Service containers: Vault dev server: `docker run -d --name secrets-api-vault -p 8201:8200 -e VAULT_DEV_ROOT_TOKEN_ID=dev-root --cap-add=IPC_LOCK hashicorp/vault@` (pin the digest you pull, and put the same digest in `ci.yml`). From inside wp-env containers it is reachable at `http://host.docker.internal:8201`. Remove the container when the flight's work is done. You do not need Moto: test the AWS naming fix by capturing the outgoing request with the `pre_http_request` filter. +- `docs/foundry.json` has been pre-seeded. The plan stage must keep `baseBranch: "main"`, + `branchPrefix: "build/"`, `permissionMode: "auto"`, and the two `verify` commands with their + timeouts exactly as they are. It may add `extraVerify` entries only for make targets that + already exist when the entry is first exercised. + +## 8. Phases + +1. **Examples harness, Vault half.** `build/kms-keyring` is building the shared harness in parallel (see §9). Create only what this example needs, using exactly the names in the KMS spec's section 5: `phpunit-examples.xml.dist`, `examples//tests/`, `make test-examples`, and a CI job named `examples` with a Vault service container. Do not add Moto, the KMS tests, or the AWS conformance class. +2. **Vault provider core:** path mapping, `get`, `set`, `delete`, the conformance suite green against the dev server, and `max_versions: 2` on create. +3. **Versions and retirement:** strict N-1 `PREVIOUS`, `retire_previous()` by destroy, and the "retiring does not resurrect" and "only two versions" tests. +4. **Metadata and listing:** `needs_rotation` in `custom_metadata`, including the flag-failure rule; `list_secrets()` with its recursive LIST; the multisite isolation test; and the sealed-or-unreachable test. +5. **AWS Secrets Manager site-scope fix** (deliverable 3), as a separate commit with its own README note. +6. **Documentation and journal.** See §2. Also write `examples/vault-provider/README.md`, with a written answer to each of the four questions, add the example to `examples/README.md`'s table, and add the Vault finding to `docs/journal/proposal-questions.md` question 2. Manual check: an OpenBao run, marked NOT VERIFIED (human). + +Every phase ends by pushing the branch. Each phase's manual check is whatever the detailed spec +lists as human or live-cloud. Mark it `NOT VERIFIED (human)` and move on. + +## 9. Open questions + +- The shared examples harness (KMS spec §5) is built by `build/kms-keyring`. Where another + flight also needs it, it builds a compatible subset with identical names, and the two are + reconciled when the branches merge. Decision: accept that merge cost rather than serialise the + flights. +- If a finding would change an interface's signature, stop and record it. Write an entry in + `docs/journal/open-questions.md` and say so in the journal entry, rather than changing the + signature. That is for the Trac ticket to decide. + +## Appendix + +Only this flight's detailed spec, `examples/vault-provider/SPEC.md`, is in scope.

No phase is merged. +- SPEC §8 phase 2 wants the conformance suite green, but `retire_previous()` is phase 3 and + `list_secrets()` is phase 4 → phase 2 lands every interface method in its simplest correct form + (`retire_previous()` destroys N-1 when one exists; `list_secrets()` returns names with blank + metadata), and phases 3 and 4 complete the semantics and add their tests. Nothing is stubbed to + throw, and no test is skipped to get there. +- Request timeout (detailed spec gives none; SPEC §5) → `⚠️ ASSUMPTION` class constant + `Vault_KV2_Provider::REQUEST_TIMEOUT = 5` seconds, justified in a comment, never repeated as a + literal. Measured in P4-02. +- `max_versions` → class constant `Vault_KV2_Provider::MAX_VERSIONS = 2`. Given by the detailed + spec, so not an assumption, but still never a literal elsewhere. +- "A set without the flag clears it" → clearing writes `custom_metadata.needs_rotation = "0"`. + Vault replaces the whole `custom_metadata` map on `POST metadata`, and an empty PHP array + JSON-encodes as `[]`, which Vault rejects, so "0" is the unambiguous clear. The flag reads as + set only when the string is exactly `"1"`. +- Vault `LIST` → `GET ?list=true`, which Vault documents as equivalent. `WP_Http`'s support + for a custom `LIST` verb is not worth depending on in a drop-in. +- `list_secrets( $name_prefix )` → `$name_prefix` is a namespace, exactly as + `WP_Secrets_Libsodium_Provider::list_secrets()` treats it: with a prefix, only + `wp///` is listed. That is also the cheapest shape for question 4. +- `wp_secret_changed` fingerprints → `''` for old and new, as the AWS example does. Fired with + `created`/`updated` from `set()`, `deleted` from `delete()`, and `retired` from + `retire_previous()` when a version was actually destroyed, matching the shipped provider. +- Order of action and flag error in `set()` → the action fires as soon as the value write + succeeds; a failed flag write with the flag requested then returns `WP_Error`. The value did + change, and an audit hook that misses a change is worse than one that sees a change whose flag + failed. +- Fingerprint scope → `$network ? 'network' : 'site'` and `$network ? null : get_current_blog_id()`, + as the shipped provider does. The AWS example uses `'site'` for both; that inconsistency is + pre-existing, out of scope, and noted in the journal entry. +- Vault image → pull `hashicorp/vault:latest` once in P1-01, record the digest and the version + `GET /v1/sys/health` reports, and pin that digest everywhere it appears (Makefile comment, + `ci.yml`, README). The detailed spec names no version. +- Test server configuration → environment variables `VAULT_ADDR` (default `http://127.0.0.1:8200`) + and `VAULT_TOKEN` (default `dev-root`), the names the Vault CLI uses. Locally, inside wp-env, + `VAULT_ADDR=http://host.docker.internal:8201`. Tests fail, never skip, when Vault is unreachable: + `make test-examples` exists to run against a server. +- Test isolation on a persistent backend → every Vault test class wipes everything under + `wp/` on the mount in `set_up()` through the test helper, because `WP_UnitTestCase`'s database + rollback does not reach Vault and the conformance suite reuses `conformance/subject`. +- Multisite tests → one file gated with `markTestSkipped()` when `! is_multisite()`. That is the + environment gate SPEC §3 allows. `make test-examples` runs the suite twice, once with + `WP_MULTISITE=1`. +- A new ADR → yes, one: `docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md`, for the + decision that the provider sets `max_versions: 2` rather than widen the version model. Number + 0009 expects renumbering at merge (SPEC §3). +- `extraVerify` → none.

SPEC §7: this worktree's wp-env is on ports 8920/8921; never touch `.wp-env.override.json`. Detailed spec, Deliverable 2: the harness bootstraps through `tests/bootstrap.php` and loads each example's `secrets.php` without its install block, which happens naturally because the `WP_SECRETS_VAULT_*` constants are undefined under test. +- `phpunit-examples.xml.dist`: copy the attributes of `phpunit.xml.dist` (bootstrap becomes `tests/bootstrap-examples.php`), one testsuite `examples` with `examples/vault-provider/tests`, no `` block, and **no** `` block: multisite is selected by the `WP_MULTISITE=1` environment variable, which the WordPress test bootstrap honours, so one config file serves both passes. +- `tests/bootstrap-examples.php`: `require_once __DIR__ . '/bootstrap.php';` then `require_once` every `examples/*/tests/includes/*.php` (glob, sorted) and then every `examples/*/secrets.php` (glob, sorted). File docblock explains that install blocks are inert under test because their constants are undefined. Must pass `phpcs` (it is under `tests/`, which `phpcs.xml.dist` lints with the test relaxations). +- `Makefile`: target `test-examples` with help text `## Run the examples suite against live service containers (not part of ci).` running `$(VENDOR_BIN)/phpunit -c phpunit-examples.xml.dist` and then `WP_MULTISITE=1 $(VENDOR_BIN)/phpunit -c phpunit-examples.xml.dist`. Above it, a comment block with the exact local Vault command, digest filled in: + `docker run -d --name secrets-api-vault -p 8201:8200 -e VAULT_DEV_ROOT_TOKEN_ID=dev-root --cap-add=IPC_LOCK hashicorp/vault@sha256:` and the wp-env invocation from Conventions. Add `test-examples` to `.PHONY`. Do not add it to `ci`. +- `.gitignore`: add `/phpunit-examples.xml` beside the other local phpunit overrides. +- Pull the image first: `docker pull hashicorp/vault:latest`, then + `docker image inspect hashicorp/vault:latest --format '{{index .RepoDigests 0}}'` gives `hashicorp/vault@sha256:`. Start the container with the pinned digest, wait for `curl -s http://127.0.0.1:8201/v1/sys/health` to return `"sealed":false`, and record the digest and the `version` field in the commit body and the progress log. P1-02 and P6-01 copy the digest from the Makefile comment. +- `class-vault-test-server.php` declares `final class Vault_Test_Server` (not a test case), constructed with no arguments from `getenv( 'VAULT_ADDR' )` (default `http://127.0.0.1:8200`), `getenv( 'VAULT_TOKEN' )` (default `dev-root`), mount `secret`. Public methods: `addr()`, `token()`, `mount()`, `provider()` (returns `new Vault_KV2_Provider( addr, token, mount )` — this method is added in P2-01; in P1-01 leave it out), `request( $method, $path, $body = null )` returning `array( 'code' => int, 'body' => array|null )` via `wp_remote_request()` with the Vault headers and a 10 s timeout (a literal is fine here: `tests/` is excluded from the timeout constraint), `health()` (decoded `sys/health`), `metadata( $vault_path )` (decoded `data` of `GET secret/metadata/`, or `null` on 404), `read_version( $vault_path, $version )` (HTTP code of `GET secret/data/?version=N`), `create_metadata( $vault_path, $max_versions )` (`POST secret/metadata/`), `soft_delete_versions( $vault_path, array $versions )` (`POST secret/delete/`), `list_keys( $vault_path )` (keys array, or `array()` on 404), and `wipe()` which lists recursively from `secret/metadata/wp/` and `DELETE`s `secret/metadata/` for every non-directory key. `$vault_path` arguments are paths under the mount, such as `wp/site/1/acme/key`. +**Acceptance tests:** `examples/vault-provider/tests/test-vault-harness.php`, class `Tests_Vault_Harness extends WP_UnitTestCase`: +- `test_the_dev_server_is_reachable_and_unsealed` — `health()` has `initialized === true` and `sealed === false`. +- `test_kv_v2_is_mounted_at_secret` — `GET sys/mounts` reports `secret/` with `options.version === "2"` (check both the top-level key and `data['secret/']`, Vault returns both). +- `test_wipe_removes_everything_under_wp` — write `wp/site/1/harness/one` and `wp/network/harness/two` with `request( 'POST', 'secret/data/...' )`, call `wipe()`, then `list_keys( 'wp/' )` is `array()` and `metadata( 'wp/site/1/harness/one' )` is `null`. +**Out of scope:** `Vault_KV2_Provider` itself, the CI job, Moto, any KMS or AWS test, any edit to `phpunit.xml.dist`, `phpunit-multisite.xml.dist`, `phpcs.xml.dist`, or `.wp-env.json`. +**Verification:** `docker ps` shows `secrets-api-vault`; the examples suite, both passes (3 tests green each); `bin/ci-local.sh --keep`; `make reference-check`. +**Depends on:** none + +### P1-02: Add the `examples` CI job with a Vault service container +**Goal:** Give `make test-examples` a hosted run against a real Vault, pinned by digest, without touching the existing jobs. +**Files touched:** `.github/workflows/ci.yml`. +**Design constraints:** SPEC §3 "Parallel flights": additive only, one new job appended after `test-multisite`, no edit to any existing job. `ci.yml`'s own rule: every action pinned by full commit SHA (copy the exact `uses:` lines and SHAs from the `test-multisite` job) and the Vault image pinned by the digest recorded in the Makefile comment from P1-01. Detailed spec, Deliverable 2: dev mode, root token through `VAULT_DEV_ROOT_TOKEN_ID`, KV v2 at `secret/` by default. +- Job `examples`, `name: Examples`, `needs: static`, `runs-on: ubuntu-latest`, PHP 8.3 with `sodium, mysqli`, the same `mysql` service block as `test-multisite`, plus a `vault` service: `image: hashicorp/vault@sha256:`, `env: VAULT_DEV_ROOT_TOKEN_ID: dev-root`, `ports: ['8200:8200']`, `options: >-` with `--cap-add=IPC_LOCK --health-cmd="wget -qO- http://127.0.0.1:8200/v1/sys/health" --health-interval=5s --health-timeout=3s --health-retries=10`. +- Steps: checkout, setup-php, composer cache (key `composer-${{ runner.os }}-php8.3-...`), `make install WP_VERSION=latest DB_HOST=127.0.0.1`, then `make test-examples` with `env: VAULT_ADDR: http://127.0.0.1:8200` and `VAULT_TOKEN: dev-root`. +- A comment above the job says why it is outside `make ci` (needs a service container `make ci`'s environments do not provide, as `examples/README.md` and the KMS spec §5 say) and that the digest is the one the Makefile comment names. +**Acceptance tests:** none executable locally beyond YAML validity: `python3 -c "import yaml,sys; yaml.safe_load(open('.github/workflows/ci.yml'))"` (or `npx --yes js-yaml .github/workflows/ci.yml >/dev/null` if Python has no PyYAML) exits 0.

SPEC §3: single file, no Composer, no SDK, readable top to bottom; errors not exceptions (never `throw`); no plaintext in any `WP_Error` message or log line; request-scoped memo only, never `wp_cache_set()`/transients/options; three states never collapse (absent is `null`, unreachable is `WP_Error`). SPEC §5: the timeout is `⚠️ ASSUMPTION`. +- File header docblock in the AWS example's voice: what it is, why a provider, "the part that is a translation" (integer versions versus two slots, pointing at the README for the four answers), that the data write and metadata write are two requests and not a transaction, and that fingerprints still need the site's own key material. +- `defined( 'ABSPATH' ) || exit;` then `final class Vault_KV2_Provider implements WP_Secrets_Provider`. +- Class constants: `MAX_VERSIONS = 2` (comment: makes Vault a two-slot store; see README question 2), `REQUEST_TIMEOUT = 5` (comment starting `⚠️ ASSUMPTION:` — every secret read waits on this; long enough for a cold TLS handshake to a remote Vault, short enough that an outage fails a page in seconds rather than tying up PHP workers; measured in P4-02), `ROTATION_FLAG = 'needs_rotation'`. +- Constructor `__construct( $addr, $token, $mount = 'secret', $namespace = '' )`; `$addr` stored with trailing slashes trimmed, `$mount` with slashes trimmed. Private properties `$addr`, `$token`, `$mount`, `$namespace`, `$memo = array()`. +- Private `scope_prefix( $network )` → `'wp/network/'` or `'wp/site/' . get_current_blog_id() .

Private `url( $kind, $vault_path, array $query = array() )` → `{addr}/v1/{mount}/{kind}/{vault_path}` plus `?query`, where `$kind` is `data`, `metadata`, `destroy`, or `delete`. +- Private `request( $method, $url, $body = null )` → decoded `data` array on 2xx (an empty array for 204), `null` on 404, otherwise `WP_Error( WP_SECRETS_ERROR_STORE_UNAVAILABLE, ... )`. Transport failure: message `Vault unreachable: `. Non-2xx: message `Vault error (HTTP ): `, falling back to the raw body when `errors` is absent. 403 and 503 both go through this branch, so permission denied and sealed both read as unreachable. Body is `wp_json_encode( $body )` when non-null. Uses `wp_remote_request()` with `'method'`, `'timeout' => self::REQUEST_TIMEOUT`, and the headers listed in Conventions; `X-Vault-Namespace` only when `'' !== $this->namespace`. +- Private `read_metadata( $name, $network )` → `request( 'GET', url( 'metadata', ... ) )`. +- Private `previous_version( $meta )` → `int|null`: `$n = (int) $meta['current_version']`; `null` when `$n < 2`; `$v = $meta['versions'][ (string) ( $n - 1 ) ]` or `null` when missing; `null` when `! empty( $v['deletion_time'] )` or `! empty( $v['destroyed'] )`; otherwise `$n - 1`.

Decision: the provider sets `max_versions: 2` on every secret it creates; `PREVIOUS` is strictly version N-1 and `null` when N-1 is missing, soft-deleted, or destroyed; retirement destroys rather than soft-deletes. Consequences: a secret created outside the provider keeps its own policy and may hold hidden versions; retiring can leave no previous version at all, by design; the interface docblock does not yet say what "previous" means, which goes to the Trac ticket via open-questions.md; if two slots prove wrong in practice this is the record to amend.

Then add two new sections before "Testability smells": `## What "previous" means on a backend with more than two versions` marked 🟡 (conservative choice: strictly N-1, in `Vault_KV2_Provider::previous_version()`; the interface docblock for `get()` and `retire_previous()` does not define it; resolution belongs on the Trac ticket description as a docblock clarification) and `## A provider outside the WordPress boundary still needs a root key` marked 🟢 (fingerprints derive from the site master key, so a `BOUNDARY_PROVIDER` provider still depends on a working keyring for one feature; inherited from the AWS example; where the code is). +- `test-coverage-gaps.md`: append a section `## 🟢 The Vault example's failure paths are simulated` (the sealed 503 and the failed flag write are produced with `pre_http_request`, not a real sealed server; the unreachable case is a real refused connection; OpenBao is not in CI, one manual run is a human check; only the pinned Vault digest is tested). +- `proposal-questions.md`, question 2: append two or three sentences: the Vault example needed a translation rather than a match; `max_versions: 2` on create made it a two-slot store and the conformance suite passed unchanged; the one thing the model did not define was what "previous" means when more than two versions exist, and the strict N-1 answer is recorded in open-questions.md for the Trac ticket. Do not alter the AWS sentence or the paragraph about silence. +- Journal entry `docs/journal/-a-vault-provider.md`, title `A Vault provider`, sections of your choosing but covering: what was built (the provider, the harness half, the CI job, the AWS fix); what it found (the AWS site-scope bug; that the conformance suite passed without changes; that the interface leaves "previous" undefined; that a provider outside the boundary still needs local key material; the AWS example's `'site'` fingerprint scope for network secrets as a small inconsistency left alone); what was left out (auth methods, `cas`, KV v1, a compatibility read for the AWS rename, any `src/` change); what it means for the Trac patch (two items for the ticket description, no signature change). Link `examples/vault-provider/README.md`, one test by name, and ADR 0008 and ADR 0009. +- `docs/index.md`: add the ADR 0009 line to "decisions/" and the journal entry line to "journal/", matching the existing line format. +**Acceptance tests:** none executable. Reviewer checks frontmatter (`head -5` of the entry shows `title`, `description`, `date` with today's date) and that no existing sentence in the three tracking pages changed (`git diff --word-diff main..HEAD -- docs/journal/open-questions.md docs/journal/test-coverage-gaps.md docs/journal/proposal-questions.md` shows only additions). +**Out of scope:** `_drafts/`; any spec page; any code; a changelog entry (no release). +**Verification:** `git diff main..HEAD --stat -- docs/journal` shows three modified files and one new file; `grep -c 'a-vault-provider' docs/index.md` is 1; `bin/ci-local.sh --keep`; `make reference-check`. +**Depends on:** P6-02 + +### P6-04: Push phase 6, remove the Vault container, and record the manual checks +**Goal:** Push the finished branch, clean up the local service container, and record every check that needs a human. +**Files touched:** `docs/PROGRESS.md` only. +**Design constraints:** SPEC §7 (remove the container when the flight's work is done); SPEC §8 (phase 6's manual check is an OpenBao run); SPEC §3 (never tag, never publish, never run `sf publish`). +**Acceptance tests:** none. +**Out of scope:** any code or docs change; a release; a tag; publishing the site. +**Verification:** `git push origin build/vault-provider`; `docker rm -f secrets-api-vault` then `docker ps -a | grep -c secrets-api-vault` is 0; progress log entry reads `Manual check: NOT VERIFIED (human)` and lists: (1) an OpenBao run: start `openbao/openbao` in dev mode on another port, point `VAULT_ADDR` at it, run the examples suite, and record the result; (2) the `examples` job is green on GitHub Actions; (3) `npm run docs:build` in `site/` renders the new README-linked pages, the ADR, and the journal entry with the sidebar sorted by date; (4) a reviewer has read `examples/vault-provider/README.md` against the four questions. +**Depends on:** P6-01, P6-03 + +## Spec issues +- SPEC §8 phase 2 requires "the conformance suite green" while `retire_previous()` is phase 3 and `list_secrets()` is phase 4, and the suite exercises both. Resolved by landing every method in its simplest correct form in P2-02 and completing semantics and tests in P3-01 and P4-01. No test is stubbed or skipped. +- SPEC §7 permits `extraVerify` only for existing make targets, but `make test-examples` runs PHPUnit on the host and this machine's WordPress test suite lives only inside wp-env, so the target cannot pass locally. No `extraVerify` is set; each task's Verification runs the wp-env command instead. The reviewer must run it by hand. +- The detailed spec says "a set without the flag clears it" without saying how. Vault replaces `custom_metadata` wholesale and rejects `[]`, so clearing writes `"0"` and the flag reads as set only for `"1"`. Recorded under Decisions and in the README. +- The detailed spec writes `LIST metadata/...`. WordPress's HTTP API is not guaranteed to pass a custom `LIST` verb through every transport, so the provider uses `GET ...?list=true`, which Vault documents as equivalent. +- The detailed spec does not say which Vault version or tag to pull. P1-01 pulls `hashicorp/vault:latest` once and pins the digest it gets; the version is recorded in the commit body. +- The detailed spec does not say what `wp_secret_changed` should carry for fingerprints from this provider. Blank strings, as in the AWS example, keep the example free of an extra read; noted as a known limit. +- The AWS example fingerprints network secrets under the `'site'` master key while the shipped provider uses `'network'`. Pre-existing, outside Deliverable 3, and left alone; the Vault provider follows the shipped provider and the journal entry notes the difference. +- `examples/README.md`'s "Dependencies" section says each binding has its own `composer.json`; neither shipped example does. Already stale before this flight, and `build/kms-keyring` may touch that page too, so it is left alone here. +- CI runs on `push` to `main` and on `pull_request`. A push to `build/vault-provider` alone does not trigger the workflow; the draft PR Foundry opens does. The phase-end manual checks say "for this branch's draft PR" for that reason. +- `WP_Secrets_Provider::set()` says a provider "must not report [`needs_rotation`] as honored". Between P2-02 and P4-01 the provider accepts the argument without writing it. That window is inside one branch and closed by P4-01; it is called out in P2-02's task text so the reviewer does not read it as a defect. +- No file under `src/`, `plugin/`, or `cli/` changes, so `docs/reference/` needs no regeneration. `make reference-check` stays in `verify` to prove it. diff --git a/docs/PROGRESS.md b/docs/PROGRESS.md new file mode 100644 index 0000000..ee96de7 --- /dev/null +++ b/docs/PROGRESS.md @@ -0,0 +1,25 @@ +# HashiCorp Vault KV v2 provider example build progress +Branch: (set by implement) +Started: (set by implement) + +## Tasks +- [ ] P1-01 Add the examples PHPUnit harness and the Vault test helper +- [ ] P1-02 Add the `examples` CI job with a Vault service container +- [ ] P1-03 Push phase 1 and record the manual checks +- [ ] P2-01 Add the Vault KV v2 provider skeleton with path mapping, HTTP client, `get()`, and `delete()` +- [ ] P2-02 Implement `set()`, `retire_previous()`, and a minimal `list_secrets()`; run the conformance suite against Vault +- [ ] P2-03 Push phase 2 and record the manual checks +- [ ] P3-01 Prove strict N-1 and destroy-on-retire against the live server +- [ ] P3-02 Push phase 3 and record the manual checks +- [ ] P4-01 Store `needs_rotation` in `custom_metadata` and fill in listing metadata +- [ ] P4-02 Multisite isolation, sealed-or-unreachable behaviour, and the timeout measurement +- [ ] P4-03 Push phase 4 and record the manual checks +- [ ] P5-01 Map AWS site scope to `wp/site//` and test it by capturing the request +- [ ] P5-02 Push phase 5 and record the manual checks +- [ ] P6-01 Write the Vault example README and update the example index, root README, and CI reference +- [ ] P6-02 Add ADR 0009 and update the spec pages' "As built" sections +- [ ] P6-03 Update the journal tracking pages, write the journal entry, and index both +- [ ] P6-04 Push phase 6, remove the Vault container, and record the manual checks + +## Log +(one entry per task, appended by implement) diff --git a/docs/foundry.json b/docs/foundry.json index bf5a94e..a14c756 100644 --- a/docs/foundry.json +++ b/docs/foundry.json @@ -9,7 +9,195 @@ "timeoutMs": 120000 } ], + "extraVerify": {}, + "build": [], "baseBranch": "main", "branchPrefix": "build/", - "permissionMode": "auto" + "permissionMode": "auto", + "maxRounds": 3, + "maxRoundsHard": 6, + "constraints": [ + { + "id": "no-filters-in-src", + "description": "No apply_filters() anywhere under src/.

The shipped provider keeps site scope per site, so the example was wrong, not the interface. Tests: examples/aws-secrets-manager/tests/test-aws-secrets-manager-naming.php, offline via pre_http_request, mirroring the Vault paths test's fake response shape: site-scope names include the blog id, network-scope names are unchanged, set() uses the same site-scoped name, listing maps site-scoped names back to WP names and ignores flat/foreign names, and (skipped off multisite) the blog id is read at call time after switch_to_blog(). Interpretation: added a private scope_prefix( $network ) returning 'wp-network/' or 'wp/site/' . get_current_blog_id() . '/', used by both aws_name() and wp_name() so the two stay in lock-step; read at call time (not cached) so a mid-request switch_to_blog() is honoured, matching the Vault provider's approach. Left the 'site' fingerprint scope for network secrets alone (tracked separately, not this task). README: rewrote the Naming section for the new shape and added "Upgrading from an earlier copy of this example" describing the AWS-side rename (create under wp/site/1/, delete the old wp/) and why no compatibility read ships before 1.0.

Retiring destroys N-1 and +never promotes N-2 into its place — if it did, `wp_retire_secret_version()`, meant to make a +compromised credential unreachable, would instead bring back an even older one. +`test_previous_is_strictly_n_minus_1_even_when_older_versions_survive` proves it: write three +versions, destroy the middle one directly against Vault, and `PREVIOUS` still reads as `null` +rather than falling back to version 1. + +### 2. The versions the API cannot see + +KV v2 keeps up to 10 versions by default; the interface exposes exactly two. This provider sets +`max_versions: 2` on every secret it creates, which makes Vault a two-slot store from its first +write. A secret created outside the provider — by `vault kv put` directly, or by an older policy — +keeps whatever `max_versions` it already had, so a pre-existing Vault secret can still hold +versions WordPress cannot see or retire. If that turns out to matter in practice it is a finding +about the version model, not a bug in this example, and goes on the Trac ticket. See +[ADR 0009](../../docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md). + +### 3. Where `needs_rotation` lives + +In `custom_metadata.needs_rotation`, as the string `"1"` (set) or `"0"` (cleared) — never omitted, +because Vault replaces `custom_metadata` wholesale on every write and rejects an empty map, so +"no flag" and "flag cleared" have to be the same write. This needs Vault 1.9 or later. The value +write and the metadata write are two separate requests, not a transaction: if the value lands and +the flag write fails, `set()` returns `WP_Error` when the caller asked for the flag (the value is +stored, but the flag is not, and the interface says a provider must not report an unhonoured flag +as honoured), and silently logs and ignores a failed *clear*. + +### 4. What `list_secrets()` costs + +One `LIST` to enumerate namespaces under the scope, one `LIST` per namespace to enumerate secrets, +and one metadata `GET` per secret found — never a data read.

Change it so that request() calls PHPUnit\Framework\Assert::fail() with the method, URL, and transport error message when wp_remote_request() returns WP_Error. metadata() returns null only on 404 and data on 200, and fails on anything else. list_keys() returns array() only on 404 and keys on 200, and fails otherwise. wipe_recursive() fails if a DELETE does not return 204. read_version(), create_metadata(), soft_delete_versions(), and request()'s return shape for non-failure codes stay as they are, so no existing test changes. Add an optional constructor argument $addr = null that, when non-null, overrides VAULT_ADDR (the token still comes from the env). Existing callers pass nothing. Test-helper code may use PHPUnit assertions; nothing here touches examples/*/secrets.php. +**Acceptance tests:** Add to Tests_Vault_Harness: test_the_helper_fails_loudly_when_vault_is_unreachable. $helper = new Vault_Test_Server( 'http://127.0.0.1:1' ). expectException( PHPUnit\Framework\AssertionFailedError::class ), then $helper->metadata( 'wp/site/1/acme/key' ). A second test, test_wipe_fails_loudly_when_vault_is_unreachable, does the same with $helper->wipe(). Both fail on the current code, where metadata() returns null and wipe() returns silently. Every existing examples test stays green against a reachable server. +**Out of scope:** Retries or longer timeouts; the provider itself (R1-01); any CI change; skipping tests when Vault is down (the plan says the suite fails, never skips). +**Verification:** Start the pinned Vault dev container and run the examples suite, both passes, inside wp-env, with the two new harness tests green. bin/ci-local.sh --keep. make reference-check. +**Depends on:** none + +### R1-03: Correct the Vault README, tracking page, root README, Makefile and ci.yml comments, and guard against leaked task IDs +**Goal:** Every published statement about the Vault example matches the code and works on any checkout. No Foundry task ID or PROGRESS.md reference remains in a shipped file, and a constraint keeps it that way. +**Files touched:** examples/vault-provider/README.md, docs/journal/test-coverage-gaps.md, README.md, Makefile, docs/foundry.json, .github/workflows/ci.yml +**Design constraints:** Additive or in-place edits confined to this flight's own sentences and sections in shared files (SPEC §3 'Parallel flights'). Do not touch any other job in ci.yml or any other Makefile target, and change comments only. Nothing private in docs. Items: (a) README 'Run the tests' and the Makefile comment above test-examples use --env-cwd="wp-content/plugins/$(basename "$PWD")" instead of the worktree-specific wp-content/plugins/vault-provider, and the README says to run them from the repository root. (b) README question 1 describes test_previous_is_strictly_n_minus_1_even_when_older_versions_survive accurately: max_versions is raised to 10 through the helper so pruning cannot be the cause, three versions are written, retire_previous() runs through the provider, PREVIOUS is null, and version 1 still reads 200. (c) README question 3 drops the false claim that Vault rejects an empty map and says the flag write merges the existing custom_metadata so other keys survive, matching R1-01's code. (d) README OpenBao section and test-coverage-gaps.md's Vault section no longer point at 'the phase-6 progress entry'. Say instead that one manual OpenBao run is a human check whose result is recorded in a commit message, as the detailed spec says. (e) test-coverage-gaps.md: the unreachable test uses a closed local port (http://127.0.0.1:1, a real refused connection), not a non-routable address. Also remove the doubled blank line before that section's '---'. (f) README.md Platform bindings sentence: make test-examples runs the Vault example against a live Vault dev server and the AWS naming tests offline through pre_http_request, not 'both against live services'. (g) Remove '(pinned digest, from P1-01)' from the Makefile comment and '(P1-01)' from the ci.yml comment, keeping the rest of each comment's meaning. (h) Add a docs/foundry.json constraint 'no-foundry-task-ids-in-shipped-files' with pattern [PR][0-9]+-[0-9]{2}\b. paths: examples/, Makefile, .github/, README.md, docs/journal/, docs/decisions/, docs/spec/, docs/reference/, src/, plugin/, cli/, tests/, bin/. shouldMatch includes the missed lines verbatim: '# Local Vault dev server for the vault-provider example (pinned digest, from P1-01):' and ' * un-deleted.

Keep baseBranch, branchPrefix, permissionMode, and the verify commands exactly as they are. +**Acceptance tests:** The new constraint is the mechanical test for the task-ID items. foundry_verify must report it ok with no fixture failure and no hits (it would have hit Makefile:59, ci.yml:193, and secrets.php before R1-01).

A metadata POST replaces +`custom_metadata` wholesale. Against the pinned Vault 2.1.1, seeding `{"owner":"ops","needs_rotation":"1"}` +and then posting `{"needs_rotation":"0"}` leaves only `{"needs_rotation":"0"}`. The docblock claims the +"0" write exists to avoid "destroying every other custom_metadata key a different tool may have +set". It does the opposite: every set or clear destroys those keys. The stated premise is also +false. Vault accepts an empty map (`{}` and even `[]` both return 204), so it is not true that +Vault "rejects an empty map", as the docblock and README question 3 say. +**What breaks:** any operator tag, owner, or ticket reference in a secret's `custom_metadata` is +silently wiped the first time WordPress sets or clears the flag. The published answer to question 3 +is wrong. `max_versions` is unaffected (verified). +**Minimal fix:** `set()` already holds `$meta` from its first read, so merge +`$meta['custom_metadata']` (when it is an array) with the flag key before posting. Correct the +docblock and README to say that the merge preserves other keys, and why "0" is still written +rather than removing the key. Mention the read-then-write race in a comment. It is the same +non-transaction the file header already names. +**Task:** P4-01 (fix R1-01). + +### 2. Category 3 (tests): the Vault test helper turns "unreachable" into "absent", so the suite cascades and negative assertions can pass vacuously +`examples/vault-provider/tests/includes/class-vault-test-server.php:76-78, 101-109, 156-164, 183-193`. + +`request()` maps a transport failure to `code 0, body null`. `metadata()` then returns `null`, which +is the same as a 404. `list_keys()` returns `array()`. `wipe()` ignores the result of every LIST +and DELETE. This is the three-state collapse CLAUDE.md forbids, moved into the test harness. I ran +the unmutated suite eight times against the local container, and it failed in about half of the +runs. The root cause is environmental: 1 in 300 TCP connects to `host.docker.internal:8201` +timed out. But the symptoms land far from that cause. A `wipe()` that silently failed left state +behind, so a later test saw `updated` instead of `created`, `custom_metadata` was null instead of +`'0'`, and `list_secrets()` was a `WP_Error` at an array index. The same collapse lets assertions +such as `assertNull( $this->server->metadata( "wp/site/{$blog}/acme/key" ) )` in +`Tests_Vault_Provider_Multisite::test_network_scope_is_shared_across_blogs` and +`Tests_Vault_Harness::test_wipe_removes_everything_under_wp` pass when Vault was never reached. +**What breaks:** CI or local failures that point at the wrong test, and negative assertions that +cannot tell "absent" from "never asked". +**Minimal fix:** the helper fails the running test loudly (`PHPUnit\Framework\Assert::fail()` with +the URL and transport error) on a transport failure. `metadata()` and `list_keys()` treat only 404 +as absent and fail on any other non-2xx. `wipe()` fails if a LIST or DELETE does not succeed. +Add an optional `$addr` constructor argument (defaulting to the env var) so a harness test can +aim the helper at a closed port. +**Task:** P1-01 (fix R1-02). + +### 3. Category 3 (tests): the unreachable-Vault test does not assert the error code the plan specifies +`examples/vault-provider/tests/test-vault-provider.php:497-503`. + +P4-02 asks that `get( CURRENT )` on `http://127.0.0.1:1` be a `WP_Error` *with code +`WP_SECRETS_ERROR_STORE_UNAVAILABLE`*. The test asserts only `assertWPError()`, for `get()`, +`list_secrets()`, and `delete()`. If the transport branch of `request()` returned any other code, +it would still pass, and the detailed spec's "Errors" rule requires "reads as unreachable". +**Minimal fix:** assert the code on all three results. This strengthens the test and weakens +nothing. +**Task:** P4-02 (folded into fix R1-01, which already touches this file). + +### 4. Category 5 (docs that do not match the code or the repository), grouped +- `examples/vault-provider/README.md:178-179` and `Makefile:62-63`: the test commands hard-code + `--env-cwd=wp-content/plugins/vault-provider`, which is this worktree's directory name. On `main` + the checkout is `secrets-management`, so the documented commands fail for anyone outside this + worktree once the branch merges. `bin/ci-local.sh` already derives the name with `basename "$PWD"`. + Use `--env-cwd="wp-content/plugins/$(basename "$PWD")"`. +- `examples/vault-provider/README.md:112-114`: question 1 says the proving test "destroy[s] the + middle one directly against Vault". The test (`test-vault-provider.php:188-201`) sets + `max_versions: 10` through the helper, writes three versions, retires through the *provider*, + and then checks that version 1 still reads 200. The pruning-cannot-be-the-cause detail is the + whole point of that test, and the README leaves it out. +- `examples/vault-provider/README.md:167` and `docs/journal/test-coverage-gaps.md:141`: both say the + OpenBao run is "recorded ... in the phase-6 progress entry". `docs/PROGRESS.md` is a Foundry + file that is stripped before merge, so this is a dangling reference in published docs. The + detailed spec says the run is recorded in a commit message. +- `docs/journal/test-coverage-gaps.md:139-140`: "the test points the provider at a non-routable + address". It uses `http://127.0.0.1:1`, a closed local port, so the connection is refused + rather than timing out. +- `README.md:147-149`: "`make test-examples` runs both against live services". The AWS tests are + offline through `pre_http_request`, and only Vault runs against a live server. +- Foundry task IDs are left in shipped files: `examples/vault-provider/secrets.php:48, 151, 269, + 309, 534` ("Measured in P4-02", "Completed in P2-02", "Isolated so P4-01's ..."), + `Makefile:59` ("from P1-01"), `.github/workflows/ci.yml:193` ("(P1-01)"). They mean nothing + once the flight's files are stripped. `secrets.php:18` also points at `../README.md` for the + four questions. The README is beside the file, and `../README.md` is `examples/README.md`. + +**Tasks:** P6-01, P6-03, P1-01, P1-02, P2-02, P4-01.

Tests: added test_setting_and_clearing_the_flag_preserves_other_custom_metadata, which seeds owner via a raw POST, then confirms both set-with-flag and set-without-flag preserve it alongside the correct needs_rotation value and MAX_VERSIONS.

Category 5 (behaviour the spec does not authorise; wrong docblock and README answer): writing the rotation flag erases every other `custom_metadata` key -`examples/vault-provider/secrets.php:613-621` (`write_flag()`), docblock at `:601-607`; -`examples/vault-provider/README.md:128-130`. - -`write_flag()` POSTs `{"custom_metadata":{"needs_rotation":"0|1"}}`. A metadata POST replaces -`custom_metadata` wholesale. Against the pinned Vault 2.1.1, seeding `{"owner":"ops","needs_rotation":"1"}` -and then posting `{"needs_rotation":"0"}` leaves only `{"needs_rotation":"0"}`. The docblock claims the -"0" write exists to avoid "destroying every other custom_metadata key a different tool may have -set". It does the opposite: every set or clear destroys those keys. The stated premise is also -false. Vault accepts an empty map (`{}` and even `[]` both return 204), so it is not true that -Vault "rejects an empty map", as the docblock and README question 3 say. -**What breaks:** any operator tag, owner, or ticket reference in a secret's `custom_metadata` is -silently wiped the first time WordPress sets or clears the flag. The published answer to question 3 -is wrong. `max_versions` is unaffected (verified). -**Minimal fix:** `set()` already holds `$meta` from its first read, so merge -`$meta['custom_metadata']` (when it is an array) with the flag key before posting. Correct the -docblock and README to say that the merge preserves other keys, and why "0" is still written -rather than removing the key. Mention the read-then-write race in a comment. It is the same -non-transaction the file header already names. -**Task:** P4-01 (fix R1-01). - -### 2. Category 3 (tests): the Vault test helper turns "unreachable" into "absent", so the suite cascades and negative assertions can pass vacuously -`examples/vault-provider/tests/includes/class-vault-test-server.php:76-78, 101-109, 156-164, 183-193`. - -`request()` maps a transport failure to `code 0, body null`. `metadata()` then returns `null`, which -is the same as a 404. `list_keys()` returns `array()`. `wipe()` ignores the result of every LIST -and DELETE. This is the three-state collapse CLAUDE.md forbids, moved into the test harness. I ran -the unmutated suite eight times against the local container, and it failed in about half of the -runs. The root cause is environmental: 1 in 300 TCP connects to `host.docker.internal:8201` -timed out. But the symptoms land far from that cause. A `wipe()` that silently failed left state -behind, so a later test saw `updated` instead of `created`, `custom_metadata` was null instead of -`'0'`, and `list_secrets()` was a `WP_Error` at an array index. The same collapse lets assertions -such as `assertNull( $this->server->metadata( "wp/site/{$blog}/acme/key" ) )` in -`Tests_Vault_Provider_Multisite::test_network_scope_is_shared_across_blogs` and -`Tests_Vault_Harness::test_wipe_removes_everything_under_wp` pass when Vault was never reached. -**What breaks:** CI or local failures that point at the wrong test, and negative assertions that -cannot tell "absent" from "never asked". -**Minimal fix:** the helper fails the running test loudly (`PHPUnit\Framework\Assert::fail()` with -the URL and transport error) on a transport failure. `metadata()` and `list_keys()` treat only 404 -as absent and fail on any other non-2xx. `wipe()` fails if a LIST or DELETE does not succeed. -Add an optional `$addr` constructor argument (defaulting to the env var) so a harness test can -aim the helper at a closed port. -**Task:** P1-01 (fix R1-02). - -### 3. Category 3 (tests): the unreachable-Vault test does not assert the error code the plan specifies -`examples/vault-provider/tests/test-vault-provider.php:497-503`. - -P4-02 asks that `get( CURRENT )` on `http://127.0.0.1:1` be a `WP_Error` *with code -`WP_SECRETS_ERROR_STORE_UNAVAILABLE`*. The test asserts only `assertWPError()`, for `get()`, -`list_secrets()`, and `delete()`. If the transport branch of `request()` returned any other code, -it would still pass, and the detailed spec's "Errors" rule requires "reads as unreachable". -**Minimal fix:** assert the code on all three results. This strengthens the test and weakens -nothing. -**Task:** P4-02 (folded into fix R1-01, which already touches this file). - -### 4. Category 5 (docs that do not match the code or the repository), grouped -- `examples/vault-provider/README.md:178-179` and `Makefile:62-63`: the test commands hard-code - `--env-cwd=wp-content/plugins/vault-provider`, which is this worktree's directory name. On `main` - the checkout is `secrets-management`, so the documented commands fail for anyone outside this - worktree once the branch merges. `bin/ci-local.sh` already derives the name with `basename "$PWD"`. - Use `--env-cwd="wp-content/plugins/$(basename "$PWD")"`. -- `examples/vault-provider/README.md:112-114`: question 1 says the proving test "destroy[s] the - middle one directly against Vault". The test (`test-vault-provider.php:188-201`) sets - `max_versions: 10` through the helper, writes three versions, retires through the *provider*, - and then checks that version 1 still reads 200. The pruning-cannot-be-the-cause detail is the - whole point of that test, and the README leaves it out. -- `examples/vault-provider/README.md:167` and `docs/journal/test-coverage-gaps.md:141`: both say the - OpenBao run is "recorded ... in the phase-6 progress entry". `docs/PROGRESS.md` is a Foundry - file that is stripped before merge, so this is a dangling reference in published docs.

Carry it into the main repo's config if you want to keep it. + +## What was built + +**Phase 1: examples harness, Vault half (P1-01 to P1-03).** Adds a PHPUnit harness for the examples: `phpunit-examples.xml.dist`, `tests/bootstrap-examples.php`, `make test-examples`, and a CI job named `examples` that runs a Vault dev server as a service container. The Vault image is pinned by digest (`sha256:47f14a6…`, Vault 2.1.1), and that digest is the same in the Makefile, `ci.yml`, and the README. The flight also adds a `Vault_Test_Server` helper that tests use to inspect Vault directly and to wipe everything under `wp/` between tests. This harness is the part the `build/kms-keyring` flight is expected to overlap with. The overlap gets reconciled at merge. + +**Phase 2: Vault provider core (P2-01 to P2-03).** Adds `examples/vault-provider/secrets.php`, a single-file drop-in with no Composer dependencies and no SDK. It defines `Vault_KV2_Provider` and talks to the KV v2 HTTP API through `WP_Http`. It maps paths to `wp/site//` and `wp/network/`. It covers every interface method in its simplest correct form, and the shared conformance suite passes against the live Vault. + +**Phase 3: versions and retirement (P3-01 to P3-02).** Tests against the live server prove two rules. First, "previous" means strictly version N-1, even when older versions still exist. Second, `retire_previous()` destroys that version outright. A soft delete is not enough. + +**Phase 4: metadata and listing (P4-01 to P4-03).** `needs_rotation` is stored in the secret's Vault `custom_metadata`, and `list_secrets()` now returns real metadata. Tests cover three more behaviours: +- Site scope is separate per blog, and network scope is shared across blogs. +- A sealed or unreachable Vault returns a `WP_Error` with code `WP_SECRETS_ERROR_STORE_UNAVAILABLE` from every method. It never reads as "absent". +- The request timeout was measured. + +**Phase 5: AWS site-scope fix (P5-01 to P5-02).** The AWS Secrets Manager example now puts site-scoped secrets under `wp/site//`. It reads the blog id when each call runs, so the name stays correct after `switch_to_blog()`. The fix is tested offline by capturing the outgoing request through `pre_http_request`. The AWS README gains an upgrade walkthrough for renaming existing secrets. + +**Phase 6: documentation and journal (P6-01 to P6-04).** This phase adds: +- The Vault example README, which answers the detailed spec's "four questions". +- ADR 0009, `docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md`. Expect to renumber it at merge. +- "As built" sections for the affected spec pages. +- Updates to the journal tracking pages, plus a new journal entry, `docs/journal/2026-09-24-a-vault-provider.md`. +- Index updates. + +Nothing under `src/`, `plugin/`, or `cli/` changed. + +**Round 1 fixes (R1-01 to R1-03).** +- R1-01: writing the rotation flag now merges with the existing `custom_metadata` instead of replacing it. Before this fix, every set or clear erased every other key in that map. +- R1-02: the test helper now fails loudly when Vault is unreachable, instead of reporting the secret as absent. +- R1-03: doc claims that had drifted from the code were corrected. A new constraint stops Foundry task IDs from appearing in shipped files. + +## Decisions that shaped it + +- **Harness scope (plan).** Only the parts of the harness this flight needs are built: phpunit config, bootstrap, `make test-examples`, the `examples` CI job, and `examples/vault-provider/tests/`. There are no Moto or KMS tests. The KMS flight's copy is reconciled at merge. +- **No interface changes (plan).** No file changed under `src/`, `plugin/`, or `cli/`, not even a docblock. Two findings concern the interface: "previous is strictly N-1", and "a `BOUNDARY_PROVIDER` provider may still need local key material". Both are recorded in `docs/journal/open-questions.md` for the Trac ticket instead of being changed in code. +- **Phases map one to one to SPEC §8 (plan).** +- **Phase 2 lands every method in its simplest form (plan, P2-02).** This keeps the conformance suite passing before phases 3 and 4 finish the semantics. Nothing is stubbed and no test is skipped. Between P2-02 and P4-01, the provider accepted `needs_rotation` without writing it. +- **`REQUEST_TIMEOUT = 5` seconds (plan, P2-01, measured in P4-02).** It is a `⚠️ ASSUMPTION` constant and appears nowhere else as a literal. +- **`MAX_VERSIONS = 2` (plan, P2-01; ADR 0009).** The provider limits Vault to two versions per secret instead of widening the WordPress version model. +- **The flag is cleared by writing `"0"` (plan, P4-01).** The flag counts as set only when the value is exactly `"1"`. The plan's stated reason, that Vault rejects an empty map, turned out to be false; see Spec issues. The choice stands as an encoding. After R1-01, the write also merges with the existing keys. +- **Listing uses `GET …?list=true` (plan, P2-02).** Vault documents it as equivalent to the `LIST` verb. The provider avoids depending on `WP_Http` passing a custom verb through every transport. +- **`$name_prefix` in `list_secrets()` is a namespace (plan, P2-02/P4-01).** This matches the libsodium provider. +- **`wp_secret_changed` fingerprints are `''` (plan, P2-02).** The AWS example does the same. It avoids an extra read, and it is a known limit. +- **In `set()`, the action fires before the flag write (plan, P2-02/P4-01).** If the flag was requested and its write fails, `set()` returns a `WP_Error`, but the audit hook has already seen the change. +- **Fingerprint scope is `'network'`/`'site'` (plan).** This matches the shipped provider. The AWS example's use of `'site'` for network secrets is an existing inconsistency that this flight left alone. +- **The Vault image is pinned by digest (plan, P1-01).** It was pulled from `latest` once. The server reports version 2.1.1. +- **Test server configuration (plan, P1-01).** It comes from `VAULT_ADDR` and `VAULT_TOKEN`. If Vault is unreachable, the tests fail rather than skip. +- **Test isolation (plan, P1-01).** Every Vault test class wipes `wp/` in `set_up()`. +- **Multisite tests (plan, P4-02).** They live in one file that is skipped when the site isn't multisite, and `make test-examples` runs the suite twice. +- **No `extraVerify` (plan).** `make test-examples` can't run on the host, so each task ran the examples suite inside wp-env instead. +- **The AWS provider reads the blog id when each call runs (interpretation, P5-01).** The private `scope_prefix()` never caches it, so the name stays correct after `switch_to_blog()`. +- **The link to ADR 0009 was broken for one commit (interpretation, P6-01).** The plan put the link in the README before P6-02 created the ADR. It works at HEAD. +- **`write_flag()` reuses the `$meta` that `set()` already read (interpretation, R1-01).** It does not fetch the metadata again, because the data write in between does not touch `custom_metadata`. The sequence of reading and then writing is not atomic, and the docblock says so. + +## Assumptions still in play + +| Key | Final default | Status | +|---|---|---| +| `Vault_KV2_Provider::REQUEST_TIMEOUT` | `5` seconds | Measured in P4-02 but not tuned: a refused connection returns in about 0.005s, and a non-routable address takes about 4s, under the limit. The value itself is still a judgment call and has not been tested against a remote Vault over TLS. | +| `Vault_KV2_Provider::MAX_VERSIONS` | `2` | Not an assumption: the detailed spec sets it and ADR 0009 records it. It is listed here because a constraint keeps it defined in one place. | + +## Spec issues + +Suggested edits to `docs/SPEC.md` or the detailed spec (`examples/vault-provider/SPEC.md`): + +- **SPEC §8, phase 2:** "conformance suite green" conflicts with the phase plan, because `retire_previous()` is phase 3 and `list_secrets()` is phase 4. State that phase 2 lands minimal forms of every method. +- **SPEC §7, `extraVerify`:** it is allowed only for existing make targets, but `make test-examples` can't run on the host. Allow a wp-env command, or add a make target that runs the suite inside wp-env. Without one, `foundry_mutate` can't see the examples suite; see Pipeline friction. +- **Detailed spec, "a set without the flag clears it":** say how the flag is cleared: write `"0"`, merge with the existing keys, and treat only `"1"` as set. Do not repeat "Vault rejects an empty map". Vault 2.1.1 accepts both `{}` and `[]`. Round 1 caught this false premise in PLAN.md. +- **Detailed spec, `LIST metadata/...`:** note that `GET …?list=true` is the accepted equivalent. +- **Detailed spec, Vault version:** name the version, or say "pin the digest". The pinned image is 2.1.1. PLAN P1-03's text asked for "a current 1.x release", which was wrong (round 1). +- **Detailed spec, fingerprints:** say what `wp_secret_changed` carries for this provider. It currently carries blank strings. +- **AWS example fingerprint scope:** it uses `'site'` for network secrets, while the shipped provider uses `'network'`. Decide whether a future spec should fix this. +- **`examples/README.md` "Dependencies":** it says each example has its own `composer.json`, but neither does. The text was already out of date, and it was left alone because the KMS flight may edit that page. +- **CI triggers:** the workflow runs only on pushes to `main` and on `pull_request`. Pushing the branch alone does not run CI, so the draft PR is what runs it. +- **`WP_Secrets_Provider::set()` contract:** the provider accepted `needs_rotation` without writing it, but only between P2-02 and P4-01 on this branch. No action needed. It is listed only because it is history. +- Round 2 found no new spec issues. + +## Manual checks owed + +**Phases 2 and 3** +1.

The real reason is the chosen encoding. The `write_flag()` docblock explanation is also thin. This is a wording issue; every factual claim is correct. + - `Vault_Test_Server::wipe_recursive()` has a non-204 DELETE check with no dedicated test: a mutation that removed it survived. The `Assert::fail()` in `request()` is only covered indirectly, by status checks that catch the same condition. + - The local examples suite still fails intermittently: 2 of 4 runs failed with `cURL error 28` to `host.docker.internal:8201`. This comes from Docker Desktop port forwarding, not the code, and failures now name the URL at the point they happen. CI should not be affected. + - Round 1 notes that still apply: + - The Foundry `.gitignore` change and the `CLAUDE.md`/`docs/SPEC.md` entries that hard-code `--env-cwd=wp-content/plugins/vault-provider` are all Foundry files. Strip them before merge. + - The install block in `secrets.php` leaves `$mount` and `$namespace` as local variables. This is harmless. + +## Pipeline friction + +- **implement, environment-flakiness:** Other Foundry flights (kms-keyring, cli-smoke) ran Docker containers on the same host at the same time. That caused intermittent connection timeouts from wp-env's tests-cli container to `host.docker.internal:8201`, so PHPUnit failed for reasons unrelated to the code. Confirming the cause was environmental took one extra debug-and-rerun cycle. +- **review, mutate-blind-spot:** `foundry_mutate` on `examples/vault-provider/secrets.php` can run only the configured verify commands, and none of them runs the examples suite. So every mutation of the example "survives" after a ~4 minute ci-local run, whatever the tests cover. The reviewer had to apply mutations by hand to a copy inside the container to get a real killed/survived result. +- **summarize, tool-refusal:** The harness refused the `Write` tool for `docs/SUMMARY.md` ("subagents should return findings as text"). The file was written with a shell heredoc instead, as the skill directs.

No phase is merged. -- SPEC §8 phase 2 wants the conformance suite green, but `retire_previous()` is phase 3 and - `list_secrets()` is phase 4 → phase 2 lands every interface method in its simplest correct form - (`retire_previous()` destroys N-1 when one exists; `list_secrets()` returns names with blank - metadata), and phases 3 and 4 complete the semantics and add their tests. Nothing is stubbed to - throw, and no test is skipped to get there. -- Request timeout (detailed spec gives none; SPEC §5) → `⚠️ ASSUMPTION` class constant - `Vault_KV2_Provider::REQUEST_TIMEOUT = 5` seconds, justified in a comment, never repeated as a - literal. Measured in P4-02. -- `max_versions` → class constant `Vault_KV2_Provider::MAX_VERSIONS = 2`. Given by the detailed - spec, so not an assumption, but still never a literal elsewhere. -- "A set without the flag clears it" → clearing writes `custom_metadata.needs_rotation = "0"`. - Vault replaces the whole `custom_metadata` map on `POST metadata`, and an empty PHP array - JSON-encodes as `[]`, which Vault rejects, so "0" is the unambiguous clear. The flag reads as - set only when the string is exactly `"1"`. -- Vault `LIST` → `GET ?list=true`, which Vault documents as equivalent. `WP_Http`'s support - for a custom `LIST` verb is not worth depending on in a drop-in. -- `list_secrets( $name_prefix )` → `$name_prefix` is a namespace, exactly as - `WP_Secrets_Libsodium_Provider::list_secrets()` treats it: with a prefix, only - `wp///` is listed. That is also the cheapest shape for question 4. -- `wp_secret_changed` fingerprints → `''` for old and new, as the AWS example does. Fired with - `created`/`updated` from `set()`, `deleted` from `delete()`, and `retired` from - `retire_previous()` when a version was actually destroyed, matching the shipped provider. -- Order of action and flag error in `set()` → the action fires as soon as the value write - succeeds; a failed flag write with the flag requested then returns `WP_Error`. The value did - change, and an audit hook that misses a change is worse than one that sees a change whose flag - failed. -- Fingerprint scope → `$network ? 'network' : 'site'` and `$network ? null : get_current_blog_id()`, - as the shipped provider does. The AWS example uses `'site'` for both; that inconsistency is - pre-existing, out of scope, and noted in the journal entry. -- Vault image → pull `hashicorp/vault:latest` once in P1-01, record the digest and the version - `GET /v1/sys/health` reports, and pin that digest everywhere it appears (Makefile comment, - `ci.yml`, README). The detailed spec names no version. -- Test server configuration → environment variables `VAULT_ADDR` (default `http://127.0.0.1:8200`) - and `VAULT_TOKEN` (default `dev-root`), the names the Vault CLI uses. Locally, inside wp-env, - `VAULT_ADDR=http://host.docker.internal:8201`. Tests fail, never skip, when Vault is unreachable: - `make test-examples` exists to run against a server. -- Test isolation on a persistent backend → every Vault test class wipes everything under - `wp/` on the mount in `set_up()` through the test helper, because `WP_UnitTestCase`'s database - rollback does not reach Vault and the conformance suite reuses `conformance/subject`. -- Multisite tests → one file gated with `markTestSkipped()` when `! is_multisite()`. That is the - environment gate SPEC §3 allows. `make test-examples` runs the suite twice, once with - `WP_MULTISITE=1`. -- A new ADR → yes, one: `docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md`, for the - decision that the provider sets `max_versions: 2` rather than widen the version model. Number - 0009 expects renumbering at merge (SPEC §3). -- `extraVerify` → none. SPEC §7 allows only existing make targets, and `make test-examples` runs - PHPUnit on the host, which locally has no WordPress test suite. Every task that touches the - example runs the wp-env command in its Verification instead. -- The Vault dev container → started in P1-01, removed in P6-04, the last task. CLAUDE.md records - how to start it again. -- Journal entry date → the day P6-03 runs (`date +%Y-%m-%d`), per SPEC §2. - -## Conventions -- Branch: `build/vault-provider` (already checked out; do not create another). -- Commit title: `: ` (for example `P2-01: Add the Vault KV v2 provider - skeleton`). Body wrapped at 72 columns, explaining why, then the labelled lines - `Goal:`, `Tests:`, `Interpretation:`, `Measurement:` (tuning tasks only), `Manual check:`. -- Before every task: read `CONTRIBUTING.md`, the whole of `CLAUDE.md`, the task, and the SPEC - sections it cites. Also read `examples/aws-secrets-manager/secrets.php` before touching any - example: it is the house style for a drop-in. -- Every task's Verification includes the two `verify` commands from `docs/foundry.json` - (`bin/ci-local.sh --keep` and `make reference-check`). Tasks that touch `examples/` also run - the examples suite inside wp-env: - ``` - npx @wordpress/env run --env-cwd=wp-content/plugins/vault-provider tests-cli env VAULT_ADDR=http://host.docker.internal:8201 VAULT_TOKEN=dev-root vendor/bin/phpunit -c phpunit-examples.xml.dist - npx @wordpress/env run --env-cwd=wp-content/plugins/vault-provider tests-cli env WP_MULTISITE=1 VAULT_ADDR=http://host.docker.internal:8201 VAULT_TOKEN=dev-root vendor/bin/phpunit -c phpunit-examples.xml.dist - ``` - Below these two commands are called "the examples suite, both passes".

Never run `wp-env destroy`. Never run - `sf publish`, never tag. -- Every `phpcs:ignore` carries ` -- ` on the same line. No `phpcs.xml.dist` change is - expected in this flight; if one is unavoidable it carries a reason in an XML comment. -- Nothing about employers, customers, or internal channels in `docs/`, READMEs, or commit bodies. -- Vault HTTP shapes used throughout (mount `secret`, all under `/v1/`): - `GET secret/data/

SPEC §7: this worktree's wp-env is on ports 8920/8921; never touch `.wp-env.override.json`. Detailed spec, Deliverable 2: the harness bootstraps through `tests/bootstrap.php` and loads each example's `secrets.php` without its install block, which happens naturally because the `WP_SECRETS_VAULT_*` constants are undefined under test. -- `phpunit-examples.xml.dist`: copy the attributes of `phpunit.xml.dist` (bootstrap becomes `tests/bootstrap-examples.php`), one testsuite `examples` with `examples/vault-provider/tests`, no `` block, and **no** `` block: multisite is selected by the `WP_MULTISITE=1` environment variable, which the WordPress test bootstrap honours, so one config file serves both passes. -- `tests/bootstrap-examples.php`: `require_once __DIR__ . '/bootstrap.php';` then `require_once` every `examples/*/tests/includes/*.php` (glob, sorted) and then every `examples/*/secrets.php` (glob, sorted). File docblock explains that install blocks are inert under test because their constants are undefined. Must pass `phpcs` (it is under `tests/`, which `phpcs.xml.dist` lints with the test relaxations). -- `Makefile`: target `test-examples` with help text `## Run the examples suite against live service containers (not part of ci).` running `$(VENDOR_BIN)/phpunit -c phpunit-examples.xml.dist` and then `WP_MULTISITE=1 $(VENDOR_BIN)/phpunit -c phpunit-examples.xml.dist`. Above it, a comment block with the exact local Vault command, digest filled in: - `docker run -d --name secrets-api-vault -p 8201:8200 -e VAULT_DEV_ROOT_TOKEN_ID=dev-root --cap-add=IPC_LOCK hashicorp/vault@sha256:` and the wp-env invocation from Conventions. Add `test-examples` to `.PHONY`. Do not add it to `ci`. -- `.gitignore`: add `/phpunit-examples.xml` beside the other local phpunit overrides. -- Pull the image first: `docker pull hashicorp/vault:latest`, then - `docker image inspect hashicorp/vault:latest --format '{{index .RepoDigests 0}}'` gives `hashicorp/vault@sha256:`. Start the container with the pinned digest, wait for `curl -s http://127.0.0.1:8201/v1/sys/health` to return `"sealed":false`, and record the digest and the `version` field in the commit body and the progress log. P1-02 and P6-01 copy the digest from the Makefile comment. -- `class-vault-test-server.php` declares `final class Vault_Test_Server` (not a test case), constructed with no arguments from `getenv( 'VAULT_ADDR' )` (default `http://127.0.0.1:8200`), `getenv( 'VAULT_TOKEN' )` (default `dev-root`), mount `secret`. Public methods: `addr()`, `token()`, `mount()`, `provider()` (returns `new Vault_KV2_Provider( addr, token, mount )` — this method is added in P2-01; in P1-01 leave it out), `request( $method, $path, $body = null )` returning `array( 'code' => int, 'body' => array|null )` via `wp_remote_request()` with the Vault headers and a 10 s timeout (a literal is fine here: `tests/` is excluded from the timeout constraint), `health()` (decoded `sys/health`), `metadata( $vault_path )` (decoded `data` of `GET secret/metadata/`, or `null` on 404), `read_version( $vault_path, $version )` (HTTP code of `GET secret/data/?version=N`), `create_metadata( $vault_path, $max_versions )` (`POST secret/metadata/`), `soft_delete_versions( $vault_path, array $versions )` (`POST secret/delete/`), `list_keys( $vault_path )` (keys array, or `array()` on 404), and `wipe()` which lists recursively from `secret/metadata/wp/` and `DELETE`s `secret/metadata/` for every non-directory key. `$vault_path` arguments are paths under the mount, such as `wp/site/1/acme/key`. -**Acceptance tests:** `examples/vault-provider/tests/test-vault-harness.php`, class `Tests_Vault_Harness extends WP_UnitTestCase`: -- `test_the_dev_server_is_reachable_and_unsealed` — `health()` has `initialized === true` and `sealed === false`. -- `test_kv_v2_is_mounted_at_secret` — `GET sys/mounts` reports `secret/` with `options.version === "2"` (check both the top-level key and `data['secret/']`, Vault returns both). -- `test_wipe_removes_everything_under_wp` — write `wp/site/1/harness/one` and `wp/network/harness/two` with `request( 'POST', 'secret/data/...' )`, call `wipe()`, then `list_keys( 'wp/' )` is `array()` and `metadata( 'wp/site/1/harness/one' )` is `null`. -**Out of scope:** `Vault_KV2_Provider` itself, the CI job, Moto, any KMS or AWS test, any edit to `phpunit.xml.dist`, `phpunit-multisite.xml.dist`, `phpcs.xml.dist`, or `.wp-env.json`. -**Verification:** `docker ps` shows `secrets-api-vault`; the examples suite, both passes (3 tests green each); `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** none - -### P1-02: Add the `examples` CI job with a Vault service container -**Goal:** Give `make test-examples` a hosted run against a real Vault, pinned by digest, without touching the existing jobs. -**Files touched:** `.github/workflows/ci.yml`. -**Design constraints:** SPEC §3 "Parallel flights": additive only, one new job appended after `test-multisite`, no edit to any existing job. `ci.yml`'s own rule: every action pinned by full commit SHA (copy the exact `uses:` lines and SHAs from the `test-multisite` job) and the Vault image pinned by the digest recorded in the Makefile comment from P1-01.

SPEC §3: single file, no Composer, no SDK, readable top to bottom; errors not exceptions (never `throw`); no plaintext in any `WP_Error` message or log line; request-scoped memo only, never `wp_cache_set()`/transients/options; three states never collapse (absent is `null`, unreachable is `WP_Error`). SPEC §5: the timeout is `⚠️ ASSUMPTION`. -- File header docblock in the AWS example's voice: what it is, why a provider, "the part that is a translation" (integer versions versus two slots, pointing at the README for the four answers), that the data write and metadata write are two requests and not a transaction, and that fingerprints still need the site's own key material. -- `defined( 'ABSPATH' ) || exit;` then `final class Vault_KV2_Provider implements WP_Secrets_Provider`. -- Class constants: `MAX_VERSIONS = 2` (comment: makes Vault a two-slot store; see README question 2), `REQUEST_TIMEOUT = 5` (comment starting `⚠️ ASSUMPTION:` — every secret read waits on this; long enough for a cold TLS handshake to a remote Vault, short enough that an outage fails a page in seconds rather than tying up PHP workers; measured in P4-02), `ROTATION_FLAG = 'needs_rotation'`. -- Constructor `__construct( $addr, $token, $mount = 'secret', $namespace = '' )`; `$addr` stored with trailing slashes trimmed, `$mount` with slashes trimmed.

Transport failure: message `Vault unreachable: `. Non-2xx: message `Vault error (HTTP ): `, falling back to the raw body when `errors` is absent. 403 and 503 both go through this branch, so permission denied and sealed both read as unreachable.

They are completed in P2-02. Do not leave a `TODO` marker; the docblocks describe the final behaviour. -- Install block at the bottom, modelled on the AWS example's guard: only when `WP_SECRETS_VAULT_ADDR` and `WP_SECRETS_VAULT_TOKEN` are defined and non-empty after `trim()`; mount from `WP_SECRETS_VAULT_MOUNT` when defined and non-empty else `'secret'`; namespace from `WP_SECRETS_VAULT_NAMESPACE` when defined else `''`. -- `Vault_Test_Server::provider()` returns `new Vault_KV2_Provider( $this->addr(), $this->token(), $this->mount() )`. -**Acceptance tests:** `examples/vault-provider/tests/test-vault-provider-paths.php`, class `Tests_Vault_Provider_Paths extends WP_UnitTestCase`, entirely offline: `set_up()` installs a `pre_http_request` filter (priority 10, 3 args) that records `$url`, `$parsed_args`, and returns a queued fake response; `tear_down()` removes it.

When created: `POST metadata/` with `array( 'max_versions' => self::MAX_VERSIONS )`; `WP_Error` → return. Then `POST data/` with `array( 'data' => array( 'value' => $value ) )`; `WP_Error` → return. Clear `$this->memo`. `do_action( 'wp_secret_changed', $name, null !== $action ? $action : ( $created ? 'created' : 'updated' ), get_current_user_id(), time(), '', '' )`. Return `true`. `$needs_rotation` is accepted and not yet written; P4-01 adds the flag write after the action. The docblock already describes the final flag behaviour from the detailed spec. -- `retire_previous( $name, $network = false )`: `read_metadata()`; `WP_Error` → return; `null` → `true`; `$prev = previous_version( $meta )`; `null` → `true`; `POST destroy/` with `array( 'versions' => array( $prev ) )`; `WP_Error` → return; clear memo; fire `wp_secret_changed` with `retired`; return `true`. Docblock: destroy rather than soft delete because a soft-deleted version can be undeleted and retire means gone. -- `list_secrets( $name_prefix = '', $network = false )`: `$base = scope_prefix( $network )`. Namespaces: when `'' !== $name_prefix`, `array( $name_prefix )`; otherwise `GET metadata/?list=true`, `null` → return `array()`, `WP_Error` → return it, keep keys ending in `/` with the slash removed. For each namespace: `GET metadata//?list=true`; `null` → skip; `WP_Error` → return it; for each key not ending in `/`, append `array( 'name' => "$ns/$key", 'fingerprint' => '', 'created' => 0, 'has_previous' => false, 'needs_rotation' => false )`. Docblock says the fingerprint is `''` as in the AWS example and that P4-01's per-secret metadata read fills the other fields. Write a private `list_keys( $url )` helper returning `array|null|WP_Error` so P4-01 does not restructure this. -**Acceptance tests:** -- `examples/vault-provider/tests/test-vault-provider-conformance.php`, class `Tests_Vault_Provider_Conformance extends WP_Secrets_Provider_Conformance`: `set_up()` calls `parent::set_up()`, constructs `Vault_Test_Server`, calls `wipe()`; `provider()` returns `$this->server->provider()`. No overridden or skipped conformance test. All 13 inherited tests pass (two are skipped by the base class itself because the provider is writable; that is the base class's behaviour, not this class's). -- `examples/vault-provider/tests/test-vault-provider.php`, class `Tests_Vault_Provider extends WP_UnitTestCase`, `set_up()` wipes, `$this->server` and `$this->provider` fields: - - `test_create_sets_max_versions_to_two_in_vault_itself` — `set( 'acme/key', 'v1' )`, then `server->metadata( 'wp/site/1/acme/key' )['max_versions'] === Vault_KV2_Provider::MAX_VERSIONS`. - - `test_first_write_fires_created_and_second_fires_updated` — capture `wp_secret_changed` args; actions are `created` then `updated`, and the captured argument list never contains the plaintext. - - `test_an_explicit_action_overrides_created_or_updated` — `set( ..., false, false, 'imported' )` fires `imported`. - - `test_update_does_not_reassert_max_versions` — `server->create_metadata( 'wp/site/1/acme/key', 10 )`, then `set()` twice; `max_versions` in Vault is still `10`. (Documents the consequence recorded in ADR 0009: a secret created outside the provider keeps its own policy.) - - `test_retire_destroys_exactly_n_minus_1_and_fires_retired` — writes `v1`, `v2`; `retire_previous()` → `true`; `server->metadata()['versions']['1']['destroyed'] === true`; `read_version( path, 2 )` is 200; action `retired` fired once. - - `test_retire_with_nothing_to_retire_fires_nothing` — one write, `retire_previous()` → `true`, no `retired` action. - - `test_list_returns_names_across_namespaces_and_never_a_value` — set `alpha/one`, `alpha/two`, `beta/three` with a canary value; `list_secrets()` names are exactly those three (sorted for comparison); `wp_json_encode()` of the result does not contain the canary; `list_secrets( 'beta' )` is exactly `beta/three`. - - `test_list_on_an_empty_mount_is_an_empty_array` — after `wipe()`, `list_secrets()` is `array()`, not `WP_Error`. -**Out of scope:** the `needs_rotation` flag (P4-01); `created`/`has_previous` in listings (P4-01); the "retiring does not resurrect" and "only two versions" tests (P3-01); README. -**Verification:** the examples suite, both passes, with `Tests_Vault_Provider_Conformance` reporting 11 passed and 2 skipped (the base class's read-only skips) and `Tests_Vault_Provider` all green; `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** P2-01 - -### P2-03: Push phase 2 and record the manual checks -**Goal:** Push the branch with the provider core in place. -**Files touched:** `docs/PROGRESS.md` only. -**Design constraints:** SPEC §8. Never tag, never publish. -**Acceptance tests:** none. -**Out of scope:** any code or docs change. -**Verification:** `git push origin build/vault-provider`; progress log entry reads `Manual check: NOT VERIFIED (human)` and lists: (1) the `examples` job is green on GitHub Actions; (2) the drop-in installed on a real wp-env site with the four constants set makes `wp secret dropin` report `Provider: Vault_KV2_Provider` and `Protected by: HashiCorp Vault (...)`, and `wp secret set`/`get --reveal` round-trip through the dev server. Both steps need a human because the wp-env drop-in sits in front of PHPUnit (see the AWS README's gotcha). -**Depends on:** P2-02 - -## Phase 3 — Versions and retirement -### P3-01: Prove strict N-1 and destroy-on-retire against the live server -**Goal:** Test the version translation end to end: retiring never resurrects, only two versions survive, N-1 is strict even when older versions exist, and a soft-deleted N-1 reads as absent. -**Files touched:** `examples/vault-provider/tests/test-vault-provider.php`, `examples/vault-provider/secrets.php` only if a test exposes a defect in `previous_version()` or `retire_previous()`. -**Design constraints:** Detailed spec, question 1 and Deliverable 2's first two provider-specific tests; SPEC §8 phase 3. The rule under test is the one already in `Vault_KV2_Provider::previous_version()` (P2-01): strictly N-1, `null` when N-1 is missing, soft-deleted, or destroyed, never an older version. If a test fails, fix the provider, never the test. Tests read Vault directly through `Vault_Test_Server` where the detailed spec says "read directly rather than through the provider". -**Acceptance tests:** added to `Tests_Vault_Provider`: -- `test_retiring_does_not_resurrect_an_older_version` — write `v1`, `v2`, `v3`; `retire_previous()`; `get( PREVIOUS )` is `null` (and `assertNotWPError`); write `v4`; `get( PREVIOUS )` reveals `v3`; `get( CURRENT )` reveals `v4`. -- `test_only_two_versions_are_kept_in_vault_itself` — write `v1`, `v2`, `v3`; `server->read_version( path, 1 )` is 404; `server->metadata( path )['versions']` has no key `"1"` and `oldest_version` is `2`; version `2` and `3` read 200. -- `test_previous_is_strictly_n_minus_1_even_when_older_versions_survive` — `server->create_metadata( path, 10 )` first so the provider's `MAX_VERSIONS` does not prune; write `v1`, `v2`, `v3`; `retire_previous()`; `get( PREVIOUS )` is `null`; `server->read_version( path, 1 )` is still 200, proving the `null` came from the rule and not from pruning. This is the test that answers question 1. -- `test_a_soft_deleted_n_minus_1_reads_as_absent` — write `v1`, `v2`; `server->soft_delete_versions( path, array( 1 ) )`; `get( PREVIOUS )` is `null`; `get( CURRENT )` reveals `v2`. -- `test_a_soft_deleted_current_reads_as_absent_not_error` — write `v1`; `soft_delete_versions( path, array( 1 ) )`; `get( CURRENT )` is `null` and not `WP_Error`. -- `test_retire_clears_the_memo` — write `v1`, `v2`; `get( PREVIOUS )` reveals `v1`; `retire_previous()`; `get( PREVIOUS )` is `null` on the same provider instance. -- `test_retire_is_idempotent` — write `v1`, `v2`; `retire_previous()` twice, both `true`; `retired` fired exactly once. -**Out of scope:** `needs_rotation`, listings, multisite, sealed-server tests, README. -**Verification:** the examples suite, both passes; `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** P2-02 - -### P3-02: Push phase 3 and record the manual checks -**Goal:** Push the branch with the version semantics proven. -**Files touched:** `docs/PROGRESS.md` only. -**Design constraints:** SPEC §8. Never tag, never publish. -**Acceptance tests:** none. -**Out of scope:** any code or docs change. -**Verification:** `git push origin build/vault-provider`; progress log entry reads `Manual check: NOT VERIFIED (human)` and lists: (1) the `examples` job is green; (2) on a real site with the drop-in installed, `wp secret set`, `wp secret set` again, `wp secret retire --yes`, then `wp secret get --slot=previous` reports absence, and `vault kv metadata get` shows the retired version destroyed. -**Depends on:** P3-01 - -## Phase 4 — Metadata and listing -### P4-01: Store `needs_rotation` in `custom_metadata` and fill in listing metadata -**Goal:** Write and read the rotation flag with the detailed spec's failure rule, and make `list_secrets()` report `created`, `has_previous`, and `needs_rotation` from metadata. -**Files touched:** `examples/vault-provider/secrets.php`, `examples/vault-provider/tests/test-vault-provider.php`. -**Design constraints:** Detailed spec, "`needs_rotation`" paragraph and the `list_secrets()` row; SPEC §8 phase 4. Decisions above: clear writes `"0"`; the flag reads as set only when exactly `"1"`; the action fires before a flag failure is returned. SPEC §3: no plaintext in any log line; the log message names the path and Vault's error, never the value. Requires Vault 1.9+ for `custom_metadata`; the class docblock says so. -- Private `flag_is_set( $meta )` → `isset( $meta['custom_metadata'][ self::ROTATION_FLAG ] ) && '1' === $meta['custom_metadata'][ self::ROTATION_FLAG ]`; `false` for `null` metadata. -- Private `write_flag( $vault_path, $set )` → `POST metadata/` with `array( 'custom_metadata' => array( self::ROTATION_FLAG => $set ?

When `$wanted !== $had`: `$flag = write_flag( ... )`. If `is_wp_error( $flag )` and `$wanted`: return `new WP_Error( WP_SECRETS_ERROR_STORE_UNAVAILABLE, sprintf( 'The value was stored but Vault refused to record the rotation flag: %s', $flag->get_error_message() ) )`.

A comment above says this is two requests, not a transaction, and points at the docblock paragraph that says the same. -- `list_secrets()`: for each key, `GET metadata//`; `WP_Error` → return it; `null` (deleted between LIST and GET) → skip; otherwise `created` = `strtotime( preg_replace( '/\.\d+Z$/', 'Z', $meta['created_time'] ) )` cast to int (0 when missing or false), `has_previous` = `null !== previous_version( $meta )`, `needs_rotation` = `flag_is_set( $meta )`. Fingerprint stays `''`. The docblock states the cost: one LIST for namespaces, one LIST per namespace, one GET per secret (question 4). -**Acceptance tests:** added to `Tests_Vault_Provider` (each `set_up()` wipes): -- `test_needs_rotation_round_trips_through_custom_metadata` — `set( name, 'v', false, true )` → `true`; `server->metadata( path )['custom_metadata']['needs_rotation'] === '1'`; `list_secrets()[0]['needs_rotation'] === true`. -- `test_a_set_without_the_flag_clears_it` — set with flag, then `set( name, 'v2' )`; metadata shows `'0'`; listing shows `false`. -- `test_the_flag_is_written_on_create_when_requested` — fresh name, flag requested: exactly one `custom_metadata` POST observed via a recording `pre_http_request` filter that passes every request through by returning `false`. (Recording only; the request still goes to Vault.) -- `test_a_set_with_an_unchanged_flag_makes_no_metadata_write` — set twice without the flag; the recording filter sees no request whose body contains `custom_metadata`. -- `test_a_failed_flag_write_that_was_requested_is_an_error_after_the_value_landed` — install a `pre_http_request` filter that returns a fake 503 `{"errors":["Vault is sealed"]}` only when `'POST' === $args['method']`, the URL contains `/metadata/`, and `$args['body']` contains `custom_metadata`; `set( name, 'v', false, true )` → `WP_Error` with code `WP_SECRETS_ERROR_STORE_UNAVAILABLE` whose message does not contain `v`'s plaintext (use a distinctive canary value); remove the filter; `get( CURRENT )` reveals the canary; the `wp_secret_changed` action was fired once with `created`. -- `test_a_failed_clear_is_logged_without_the_value_and_ignored` — set with flag; `ini_set( 'error_log', )`; same selective 503 filter; `set( name, 'CANARY-clear-9c1d' )` → `true`; the log file contains `could not clear needs_rotation` and does not contain `CANARY-clear-9c1d`; restore `error_log` in `tear_down()`; metadata flag is still `'1'`. -- `test_list_reports_created_and_has_previous` — write `v1`: `created` is within 300 s of `time()` and `has_previous === false`; write `v2`: `has_previous === true`; `retire_previous()`: `has_previous === false`. -- `test_list_omits_a_secret_deleted_between_list_and_metadata_read` — set two names; a `pre_http_request` filter returns a fake 404 for the metadata GET of one of them; `list_secrets()` returns only the other, not `WP_Error`. -**Out of scope:** multisite and sealed-server tests (P4-02); README; any `src/` change. -**Verification:** the examples suite, both passes; `bin/ci-local.sh --keep`; `make reference-check`; `grep -c "'1'" examples/vault-provider/secrets.php` shows the flag string only inside `flag_is_set()` and `write_flag()`. -**Depends on:** P3-01 - -### P4-02: Multisite isolation, sealed-or-unreachable behaviour, and the timeout measurement -**Goal:** Prove site scope is per blog and network scope is shared, prove a sealed or unreachable Vault is `WP_Error` from every method, and measure the `⚠️ ASSUMPTION` timeout. -**Files touched:** `examples/vault-provider/tests/test-vault-provider-multisite.php` (new), `examples/vault-provider/tests/test-vault-provider.php`, `examples/vault-provider/secrets.php` only if the measurement changes `REQUEST_TIMEOUT` or its comment. -**Design constraints:** Detailed spec, Deliverable 2 ("Site scope is isolated per blog", "A sealed or unreachable Vault reads as `WP_Error`, never `null`"); detailed spec "Errors" (403 and 503 → `WP_SECRETS_ERROR_STORE_UNAVAILABLE`); SPEC §5 (assumption gets measured); SPEC §3 (skip only on the multisite environment gate; three states never collapse).

Write in the register of `examples/aws-secrets-manager/README.md`: plain, specific, second person where it addresses the operator. `docs/reference/ci.md` is hand-written (not generated by `bin/gen-reference.php`), so editing it is allowed. -- `examples/vault-provider/README.md` sections, in order: title and one-paragraph summary (`wp secret dropin` reports the provider boundary); **Where the credentials go** (`.wp-env.override.json` example with `WP_SECRETS_VAULT_ADDR`, `WP_SECRETS_VAULT_TOKEN`, `WP_SECRETS_VAULT_MOUNT`, `WP_SECRETS_VAULT_NAMESPACE`; from inside wp-env the dev server is `http://host.docker.internal:8201`); **Install the drop-in** (the same `docker cp` / `wp secret dropin` / removal loop as the AWS README, with the expected `wp secret dropin` output including `Protected by: HashiCorp Vault (http://..., mount secret)` and the same gotcha about PHPUnit); **Vault policy** (the smallest policy: `create`, `update`, `read`, `delete`, `list` on `secret/data/wp/*`, `secret/metadata/wp/*`, `secret/destroy/wp/*`; note that `is_writable()` returns `true` regardless and a token without write policy surfaces as `WP_Error` on `set()`); **Naming** (the path table from the detailed spec); **The four questions** with a subsection each: 1. what "previous" is (strictly N-1; retiring destroys N-1 and never promotes N-2; the test that proves it, `test_previous_is_strictly_n_minus_1_even_when_older_versions_survive`); 2. the versions the API cannot see (`max_versions: 2` on create makes Vault a two-slot store; a secret created outside the provider keeps its own `max_versions`, so pre-existing Vault secrets can still hold versions WordPress cannot see; if this turns out wrong in practice it is a finding about the version model for the Trac ticket; link ADR 0009); 3. where `needs_rotation` lives (`custom_metadata.needs_rotation = "1"`, cleared to `"0"`, Vault 1.9+, two requests not a transaction, the failure rule); 4. what `list_secrets()` costs (one LIST for namespaces, one LIST per namespace, one metadata GET per secret; no data reads; fingerprints blank as in the AWS example); **Known limits** (static token only, with AppRole and Kubernetes auth named as the production path; no `cas`, one sentence on it as the answer to concurrent writers; KV v1 and dynamic engines out of scope; request-scoped caching only; fingerprints still need the site's own root key even though the boundary is the provider, as a question rather than a promise; `wp_secret_changed` carries blank fingerprints); **OpenBao** (implements the same KV v2 API; CI tests Vault, the name hosts search for, and one manual OpenBao run is recorded in the P6-04 progress entry as a human check); **Run the tests** (the `docker run` line with the pinned digest, the two wp-env commands, `make test-examples` for a host with its own test suite, and what `VAULT_ADDR`/`VAULT_TOKEN` do). -- `examples/README.md`: add a row `| **HashiCorp Vault KV v2** | secrets | \`WP_Secrets_Provider\` | 8 methods |` to the table, and a new section `## In this directory` (placed after "Which interface do you need?") listing `aws-secrets-manager/` and `vault-provider/` with one line each. Do not edit any other sentence, including the KMS advice and the "Dependencies" section. -- `README.md`: in "Platform bindings", add one sentence naming the two shipped examples (AWS Secrets Manager, HashiCorp Vault KV v2) and that `make test-examples` runs them against live services; in "Contributing", extend the CI sentence with "plus an `examples` job that runs the platform bindings against a Vault service container". No other change. -- `docs/reference/ci.md`: add a row to the Matrix table: `| \`examples\` | 8.3 | latest | \`make test-examples\` against a Vault dev-mode service container, single site and multisite. Outside \`make ci\` because it needs the container. |`, and one sentence under "Where this runs" saying the same. No other change. -**Acceptance tests:** none executable; `bin/ci-local.sh --keep` still passes (docs are not linted). Reviewer reads the README against the detailed spec's four questions. -**Out of scope:** spec pages, ADR, journal (P6-02, P6-03); any code. -**Verification:** every relative link in the new README resolves (`grep -o '](\.\./[^)]*)' examples/vault-provider/README.md` and check each path exists); the digest in the README equals the one in `Makefile` and `ci.yml`; `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** P4-02, P5-01 - -### P6-02: Add ADR 0009 and update the spec pages' "As built" sections -**Goal:** Record the two-slot cap as a decision and bring the four affected spec pages in line with what the example showed. -**Files touched:** `docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md` (new), `docs/spec/versioning.md`, `docs/spec/rotation.md`, `docs/spec/providers-and-keyrings.md`, `docs/spec/extension-points.md`. -**Design constraints:** SPEC §3 "ADRs" (next number after 0008, same table format and sections as `docs/decisions/0008-...md`: frontmatter `title` and `description`, then Number/Date/Status table, Context, Decision, Consequences; expect renumbering at merge) and "Spec pages" (exactly three sections in order; only "As built" changes here because the code still matches the proposal, so "Why" gets nothing new). Nothing private. Date the ADR the day it is written. -- ADR 0009 title: "Cap a many-version backend to two slots". Context: KV v2 keeps up to 10 versions; the API exposes two; versions WordPress cannot see stay readable to any Vault token; "previous" needs a definition on a backend with more than two versions. Decision: the provider sets `max_versions: 2` on every secret it creates; `PREVIOUS` is strictly version N-1 and `null` when N-1 is missing, soft-deleted, or destroyed; retirement destroys rather than soft-deletes. Consequences: a secret created outside the provider keeps its own policy and may hold hidden versions; retiring can leave no previous version at all, by design; the interface docblock does not yet say what "previous" means, which goes to the Trac ticket via open-questions.md; if two slots prove wrong in practice this is the record to amend. Link the detailed spec, the README, and ADR 0008. -- `docs/spec/versioning.md` "As built": append a paragraph `**A backend with more than two versions.**` describing the Vault example's translation (strict N-1, `max_versions: 2`, destroy on retire), pointing at `examples/vault-provider/secrets.php`, `previous_version()`, and ADR 0009. -- `docs/spec/rotation.md` "As built", "Retiring the previous value": append one sentence that the Vault example implements `retire_previous()` as a destroy of exactly version N-1, since a soft-deleted version can be undeleted. -- `docs/spec/providers-and-keyrings.md` "As built", "Supporting surface": append a sentence that two provider examples exist, `examples/aws-secrets-manager/` and `examples/vault-provider/`, and that `make test-examples` runs the conformance suite against the Vault one on a real server. -- `docs/spec/extension-points.md` "As built", the conformance-suite paragraph: append a sentence that the suite also runs against the Vault provider example on a real dev server in `make test-examples`, so there is a second known-good subject whose backend does not share the two-slot shape. -**Acceptance tests:** none executable. Reviewer checks each spec page still has exactly `## As proposed`, `## As built`, `## Why` in that order (`grep -n '^## ' docs/spec/.md`). -**Out of scope:** `docs/index.md` (P6-03); journal pages; "Why" sections; any code. -**Verification:** `grep -c '^## ' docs/spec/versioning.md docs/spec/rotation.md docs/spec/providers-and-keyrings.md docs/spec/extension-points.md` reports 3 each; `ls docs/decisions/` shows 0009 as the only new file; `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** P4-02 - -### P6-03: Update the journal tracking pages, write the journal entry, and index both -**Goal:** Record what the Vault example found in the three tracking pages, write the one dev journal entry, and list the new pages in `docs/index.md`. -**Files touched:** `docs/journal/open-questions.md`, `docs/journal/test-coverage-gaps.md`, `docs/journal/proposal-questions.md`, `docs/journal/YYYY-MM-DD-a-vault-provider.md` (new, dated today), `docs/index.md`. -**Design constraints:** SPEC §2 (one entry; frontmatter `title`, `description`, `date`; voice of `docs/journal/2026-09-04-0-1-0-is-public.md`: first person, plain, specific; cover what was built, what it found, what was left out, what it means for the Trac patch; link the example or a test and ADR 0008; do not use the `/journal-entry` skill and do not touch `docs/journal/_drafts/`). SPEC §3 "Parallel flights": additive edits to the tracking pages and `docs/index.md`, confined to your own paragraphs; do not reword any existing sentence, in particular the sentence in open-questions.md about a KMS keyring having no example, which `build/kms-keyring` will edit. SPEC §9 second bullet: interface-level findings are recorded here, not changed in `src/`. Nothing private. -- `open-questions.md`: under "Host and platform providers", append a paragraph beginning `**What the Vault example added:**` (a second provider, this time against a backend whose versioning does not match; the conformance suite now runs against it automatically in `make test-examples`; what it found). Then add two new sections before "Testability smells": `## What "previous" means on a backend with more than two versions` marked 🟡 (conservative choice: strictly N-1, in `Vault_KV2_Provider::previous_version()`; the interface docblock for `get()` and `retire_previous()` does not define it; resolution belongs on the Trac ticket description as a docblock clarification) and `## A provider outside the WordPress boundary still needs a root key` marked 🟢 (fingerprints derive from the site master key, so a `BOUNDARY_PROVIDER` provider still depends on a working keyring for one feature; inherited from the AWS example; where the code is). -- `test-coverage-gaps.md`: append a section `## 🟢 The Vault example's failure paths are simulated` (the sealed 503 and the failed flag write are produced with `pre_http_request`, not a real sealed server; the unreachable case is a real refused connection; OpenBao is not in CI, one manual run is a human check; only the pinned Vault digest is tested). -- `proposal-questions.md`, question 2: append two or three sentences: the Vault example needed a translation rather than a match; `max_versions: 2` on create made it a two-slot store and the conformance suite passed unchanged; the one thing the model did not define was what "previous" means when more than two versions exist, and the strict N-1 answer is recorded in open-questions.md for the Trac ticket. Do not alter the AWS sentence or the paragraph about silence. -- Journal entry `docs/journal/-a-vault-provider.md`, title `A Vault provider`, sections of your choosing but covering: what was built (the provider, the harness half, the CI job, the AWS fix); what it found (the AWS site-scope bug; that the conformance suite passed without changes; that the interface leaves "previous" undefined; that a provider outside the boundary still needs local key material; the AWS example's `'site'` fingerprint scope for network secrets as a small inconsistency left alone); what was left out (auth methods, `cas`, KV v1, a compatibility read for the AWS rename, any `src/` change); what it means for the Trac patch (two items for the ticket description, no signature change). Link `examples/vault-provider/README.md`, one test by name, and ADR 0008 and ADR 0009. -- `docs/index.md`: add the ADR 0009 line to "decisions/" and the journal entry line to "journal/", matching the existing line format. -**Acceptance tests:** none executable. Reviewer checks frontmatter (`head -5` of the entry shows `title`, `description`, `date` with today's date) and that no existing sentence in the three tracking pages changed (`git diff --word-diff main..HEAD -- docs/journal/open-questions.md docs/journal/test-coverage-gaps.md docs/journal/proposal-questions.md` shows only additions). -**Out of scope:** `_drafts/`; any spec page; any code; a changelog entry (no release). -**Verification:** `git diff main..HEAD --stat -- docs/journal` shows three modified files and one new file; `grep -c 'a-vault-provider' docs/index.md` is 1; `bin/ci-local.sh --keep`; `make reference-check`. -**Depends on:** P6-02 - -### P6-04: Push phase 6, remove the Vault container, and record the manual checks -**Goal:** Push the finished branch, clean up the local service container, and record every check that needs a human. -**Files touched:** `docs/PROGRESS.md` only. -**Design constraints:** SPEC §7 (remove the container when the flight's work is done); SPEC §8 (phase 6's manual check is an OpenBao run); SPEC §3 (never tag, never publish, never run `sf publish`). -**Acceptance tests:** none. -**Out of scope:** any code or docs change; a release; a tag; publishing the site. -**Verification:** `git push origin build/vault-provider`; `docker rm -f secrets-api-vault` then `docker ps -a | grep -c secrets-api-vault` is 0; progress log entry reads `Manual check: NOT VERIFIED (human)` and lists: (1) an OpenBao run: start `openbao/openbao` in dev mode on another port, point `VAULT_ADDR` at it, run the examples suite, and record the result; (2) the `examples` job is green on GitHub Actions; (3) `npm run docs:build` in `site/` renders the new README-linked pages, the ADR, and the journal entry with the sidebar sorted by date; (4) a reviewer has read `examples/vault-provider/README.md` against the four questions. -**Depends on:** P6-01, P6-03 - -## Spec issues -- SPEC §8 phase 2 requires "the conformance suite green" while `retire_previous()` is phase 3 and `list_secrets()` is phase 4, and the suite exercises both. Resolved by landing every method in its simplest correct form in P2-02 and completing semantics and tests in P3-01 and P4-01. No test is stubbed or skipped. -- SPEC §7 permits `extraVerify` only for existing make targets, but `make test-examples` runs PHPUnit on the host and this machine's WordPress test suite lives only inside wp-env, so the target cannot pass locally. No `extraVerify` is set; each task's Verification runs the wp-env command instead. The reviewer must run it by hand. -- The detailed spec says "a set without the flag clears it" without saying how. Vault replaces `custom_metadata` wholesale and rejects `[]`, so clearing writes `"0"` and the flag reads as set only for `"1"`. Recorded under Decisions and in the README. -- The detailed spec writes `LIST metadata/...`. WordPress's HTTP API is not guaranteed to pass a custom `LIST` verb through every transport, so the provider uses `GET ...?list=true`, which Vault documents as equivalent. -- The detailed spec does not say which Vault version or tag to pull. P1-01 pulls `hashicorp/vault:latest` once and pins the digest it gets; the version is recorded in the commit body. -- The detailed spec does not say what `wp_secret_changed` should carry for fingerprints from this provider. Blank strings, as in the AWS example, keep the example free of an extra read; noted as a known limit. -- The AWS example fingerprints network secrets under the `'site'` master key while the shipped provider uses `'network'`. Pre-existing, outside Deliverable 3, and left alone; the Vault provider follows the shipped provider and the journal entry notes the difference. -- `examples/README.md`'s "Dependencies" section says each binding has its own `composer.json`; neither shipped example does. Already stale before this flight, and `build/kms-keyring` may touch that page too, so it is left alone here. -- CI runs on `push` to `main` and on `pull_request`. A push to `build/vault-provider` alone does not trigger the workflow; the draft PR Foundry opens does. The phase-end manual checks say "for this branch's draft PR" for that reason. -- `WP_Secrets_Provider::set()` says a provider "must not report [`needs_rotation`] as honored". Between P2-02 and P4-01 the provider accepts the argument without writing it. That window is inside one branch and closed by P4-01; it is called out in P2-02's task text so the reviewer does not read it as a defect. -- No file under `src/`, `plugin/`, or `cli/` changes, so `docs/reference/` needs no regeneration. `make reference-check` stays in `verify` to prove it. - -## Review fixes (round 1) - -### R1-01: Preserve other custom_metadata keys when writing the rotation flag, and tighten the Vault provider's docblocks and unreachable test -**Goal:** write_flag() merges the secret's existing custom_metadata with the needs_rotation key instead of replacing the whole map, the docblocks state what Vault actually does, no Foundry task IDs remain in the drop-in, and the unreachable-Vault test asserts the error code. -**Files touched:** examples/vault-provider/secrets.php, examples/vault-provider/tests/test-vault-provider.php -**Design constraints:** Detailed spec, needs_rotation paragraph: stored as custom_metadata.needs_rotation = "1", cleared by a set without the flag; the flag-failure rule is unchanged. A POST to metadata/ replaces custom_metadata wholesale, as confirmed against the pinned Vault 2.1.1: seeding {owner:ops,needs_rotation:1} and then posting {needs_rotation:0} leaves only needs_rotation. Vault accepts an empty map, so the existing docblock claim that it 'rejects an empty map' is false. Change write_flag( $vault_path, $set ) to take the metadata set() already read, e.g. write_flag( $vault_path, $set, $meta ). Post array_merge( existing custom_metadata when it is an array, else array(), array( self::ROTATION_FLAG => $set ? '1' : '0' ) ). Keep writing "0" to clear, and keep flag_is_set() reading exactly "1". Rewrite the write_flag() docblock to say that the merge preserves keys other tools set and that reading then writing is not atomic (the same two-requests-not-a-transaction caveat as the file header). Do not add a PATCH request. In the same file, replace every Foundry task-ID reference in docblocks (lines ~48 'Measured in P4-02', ~151 '(P4-01)', ~269 'Completed in P2-02.', ~309 'Completed in P2-02 and P4-01.', ~534 'Isolated so P4-01's ...') with plain statements of behaviour. REQUEST_TIMEOUT's comment should state the measurement: refused connection about 0.005 s, non-routable address about 4 s. Change line 18's '../README.md' to 'README.md' (the README beside the file). No new literal 'max_versions' or 'timeout' numbers; no plaintext in any message. Tests only get stronger. -**Acceptance tests:** Add to Tests_Vault_Provider: test_setting_and_clearing_the_flag_preserves_other_custom_metadata. set( 'acme/key', 'v1' ). Then $this->server->request( 'POST', 'secret/metadata/wp/site/1/acme/key', array( 'custom_metadata' => array( 'owner' => 'ops' ) ) ). Then set( 'acme/key', 'v2', false, true ): metadata custom_metadata has owner === 'ops' and needs_rotation === '1'. Then set( 'acme/key', 'v3' ): owner === 'ops' and needs_rotation === '0', and max_versions is still Vault_KV2_Provider::MAX_VERSIONS. This fails on the current code, where owner disappears. Strengthen test_an_unreachable_vault_is_an_error_not_absence to also assertSame( WP_SECRETS_ERROR_STORE_UNAVAILABLE, ...->get_error_code() ) for get( CURRENT ), list_secrets(), and delete(). All existing tests stay unchanged and green. -**Out of scope:** README and journal wording (R1-03); the test helper's error handling (R1-02); any src/, plugin/, cli/ change; a PATCH-based metadata write; cas. -**Verification:** php -l examples/vault-provider/secrets.php. grep -nE '[PR][0-9]-[0-9][0-9]' examples/vault-provider/secrets.php is empty. Start the pinned Vault dev container and run the examples suite, both passes, inside wp-env (single site and WP_MULTISITE=1), with the new test green. bin/ci-local.sh --keep. make reference-check. -**Depends on:** none - -### R1-02: Make Vault_Test_Server fail loudly when Vault is unreachable instead of reporting absence -**Goal:** The test helper never turns a transport failure or unexpected status into 'absent' or 'wiped'. It fails the running test with the URL and error, so a flaky connection fails where it happens, and negative assertions cannot pass when Vault was never reached. -**Files touched:** examples/vault-provider/tests/includes/class-vault-test-server.php, examples/vault-provider/tests/test-vault-harness.php -**Design constraints:** CLAUDE.md: three states never collapse; tests only get stronger. request() currently maps a WP_Error from wp_remote_request() to code 0 / body null. metadata() then returns null (the same as 404), list_keys() returns array(), and wipe() ignores every LIST and DELETE result. Change it so that request() calls PHPUnit\Framework\Assert::fail() with the method, URL, and transport error message when wp_remote_request() returns WP_Error. metadata() returns null only on 404 and data on 200, and fails on anything else. list_keys() returns array() only on 404 and keys on 200, and fails otherwise. wipe_recursive() fails if a DELETE does not return 204. read_version(), create_metadata(), soft_delete_versions(), and request()'s return shape for non-failure codes stay as they are, so no existing test changes. Add an optional constructor argument $addr = null that, when non-null, overrides VAULT_ADDR (the token still comes from the env). Existing callers pass nothing. Test-helper code may use PHPUnit assertions; nothing here touches examples/*/secrets.php. -**Acceptance tests:** Add to Tests_Vault_Harness: test_the_helper_fails_loudly_when_vault_is_unreachable. $helper = new Vault_Test_Server( 'http://127.0.0.1:1' ). expectException( PHPUnit\Framework\AssertionFailedError::class ), then $helper->metadata( 'wp/site/1/acme/key' ). A second test, test_wipe_fails_loudly_when_vault_is_unreachable, does the same with $helper->wipe(). Both fail on the current code, where metadata() returns null and wipe() returns silently. Every existing examples test stays green against a reachable server. -**Out of scope:** Retries or longer timeouts; the provider itself (R1-01); any CI change; skipping tests when Vault is down (the plan says the suite fails, never skips). -**Verification:** Start the pinned Vault dev container and run the examples suite, both passes, inside wp-env, with the two new harness tests green. bin/ci-local.sh --keep. make reference-check. -**Depends on:** none - -### R1-03: Correct the Vault README, tracking page, root README, Makefile and ci.yml comments, and guard against leaked task IDs -**Goal:** Every published statement about the Vault example matches the code and works on any checkout. No Foundry task ID or PROGRESS.md reference remains in a shipped file, and a constraint keeps it that way. -**Files touched:** examples/vault-provider/README.md, docs/journal/test-coverage-gaps.md, README.md, Makefile, docs/foundry.json, .github/workflows/ci.yml -**Design constraints:** Additive or in-place edits confined to this flight's own sentences and sections in shared files (SPEC §3 'Parallel flights'). Do not touch any other job in ci.yml or any other Makefile target, and change comments only. Nothing private in docs. Items: (a) README 'Run the tests' and the Makefile comment above test-examples use --env-cwd="wp-content/plugins/$(basename "$PWD")" instead of the worktree-specific wp-content/plugins/vault-provider, and the README says to run them from the repository root. (b) README question 1 describes test_previous_is_strictly_n_minus_1_even_when_older_versions_survive accurately: max_versions is raised to 10 through the helper so pruning cannot be the cause, three versions are written, retire_previous() runs through the provider, PREVIOUS is null, and version 1 still reads 200. (c) README question 3 drops the false claim that Vault rejects an empty map and says the flag write merges the existing custom_metadata so other keys survive, matching R1-01's code. (d) README OpenBao section and test-coverage-gaps.md's Vault section no longer point at 'the phase-6 progress entry'. Say instead that one manual OpenBao run is a human check whose result is recorded in a commit message, as the detailed spec says. (e) test-coverage-gaps.md: the unreachable test uses a closed local port (http://127.0.0.1:1, a real refused connection), not a non-routable address. Also remove the doubled blank line before that section's '---'. (f) README.md Platform bindings sentence: make test-examples runs the Vault example against a live Vault dev server and the AWS naming tests offline through pre_http_request, not 'both against live services'. (g) Remove '(pinned digest, from P1-01)' from the Makefile comment and '(P1-01)' from the ci.yml comment, keeping the rest of each comment's meaning. (h) Add a docs/foundry.json constraint 'no-foundry-task-ids-in-shipped-files' with pattern [PR][0-9]+-[0-9]{2}\b. paths: examples/, Makefile, .github/, README.md, docs/journal/, docs/decisions/, docs/spec/, docs/reference/, src/, plugin/, cli/, tests/, bin/. shouldMatch includes the missed lines verbatim: '# Local Vault dev server for the vault-provider example (pinned digest, from P1-01):' and ' * un-deleted.

Now that the write merges, the merge could drop the - key just as easily. The real reason for writing `"0"` is simply the chosen encoding, since - `flag_is_set()` reads exactly `"1"`. The `write_flag()` docblock's "re-deriving the rest of the - map" explanation is similarly thin. Every factual claim is now correct: other keys survive, the - flag is `"1"`/`"0"`, Vault 1.9+ is required, and the two requests are not a transaction. This - is phrasing, not a defect. It is worth one tightening pass when a human does the Phase 6 - read-through. -- **Two helper checks have no dedicated test.** - - `Vault_Test_Server::wipe_recursive()`'s non-204 DELETE check has no test. Removing it passes - the suite, because an unreachable server fails earlier, at the LIST. The dev server never - answers a metadata DELETE with anything but 204. - - `request()`'s `Assert::fail()` is not tested on its own, because the status checks behind it - catch the same condition. - - R1-02 named its two tests, and both exist and pass. These are extra safety checks, not missing - coverage of a spec mechanic. -- **Local runs are still flaky, now with clear failure messages.** On this machine the - examples suite still fails intermittently: 2 of 4 back-to-back single-site runs. The cause is - `cURL error 28: Failed to connect to host.docker.internal port 8201 after ~5200 ms`, which is the - Docker Desktop port-forward environment property round 1 described. Since R1-02, the helper's - failures name the URL and cURL error where the connection fails. When the provider's own request - is the one that times out, it surfaces as that test's `WP_Error`. I reproduced both failing tests - green in isolation (12 of 14 runs; the other 2 failures were the same connect timeout).

Engineering principles - -- **Read first.** Before any task, read `CONTRIBUTING.md` and the "Working in this repository" section of `CLAUDE.md`. Both bind every task. -- **Keep the existing `CLAUDE.md` content.** When the plan stage writes `CLAUDE.md`, keep the current `# Working in this repository` section verbatim at the top and add the Foundry headings below it. Removing or rewording that section is a review failure. -- **`src/` is copy-ready for core.** Use core's coding standard, the `default` text domain, and `@since 7.2.0`, with no `function_exists()` guards. `tests/phpunit/test-architecture.php` enforces this. `plugin/` and `cli/` are never copied into core. -- **Errors, not exceptions.** Public API functions return `WP_Error` (or `false`) and never throw. A caller error is `_doing_it_wrong()` plus `WP_Error( WP_SECRETS_ERROR_INVALID_ARGUMENT )`. -- **No plaintext in output.** A plaintext secret or raw key material never appears in a log line, a `WP_Error` message, CLI output (except `get --reveal`), a test failure message, or a persistent cache. The reviewer checks this by reading. -- **Tests only get stronger.** Never delete or weaken an existing test. Never skip a test except for an environment gate, such as multisite-only. Every `phpcs:ignore` and every new `phpcs.xml.dist` exclusion carries a reason on the same line. -- **Generated reference.** `docs/reference/` is generated. When a docblock changes, run `make reference` and commit the result in the same task. `make reference-check` must pass. -- **Spec pages** under `docs/spec/` keep exactly three sections, in this order: **As proposed**, **As built**, **Why**. A behaviour change updates "As built", and "Why" if the code now departs from the proposal. -- **ADRs.** A new design decision gets an ADR under `docs/decisions/`, numbered `NNNN-slug.md` after the highest existing number, with number, title, date, status, context, decision, and consequences, in the existing ADRs' style. Two other flights may also add ADRs, so pick the next number and expect it to be renumbered at merge. -- **Nothing private in `docs/`.** Never mention employers, customers, or internal channels there. -- **Never publish.** Never run `sf publish`, never create or push a tag, and never touch Spacefast settings. Publishing happens after merge, by a human. -- **Commit style.** Commit messages follow `git log`: an imperative title, then a body explaining why, wrapped at 72 columns. Foundry's `: ` title prefix is fine. -- **Examples are single files.** Each example under `examples/` is a single-file drop-in with no Composer and no SDK, and stays excluded from `make ci`'s lint. It is written to be read from top to bottom. -- **Parallel flights.** Two other branches are being built from the same `main` at the same time: `build/kms-keyring` (the KMS keyring example, root-key caching, `rotate --from`, and the shared examples test harness) and `build/cli-smoke` (the WP-CLI smoke test). Do not do their work. Keep edits to shared files (`Makefile`, `.github/workflows/ci.yml`, `examples/README.md`, the `docs/journal/*.md` tracking pages, `docs/index.md`) additive and confined to your own section or entry, to make the merge easy. - -## 4.

Phases - -1. **Examples harness, Vault half.** `build/kms-keyring` is building the shared harness in parallel (see §9). Create only what this example needs, using exactly the names in the KMS spec's section 5: `phpunit-examples.xml.dist`, `examples//tests/`, `make test-examples`, and a CI job named `examples` with a Vault service container. Do not add Moto, the KMS tests, or the AWS conformance class. -2. **Vault provider core:** path mapping, `get`, `set`, `delete`, the conformance suite green against the dev server, and `max_versions: 2` on create. -3. **Versions and retirement:** strict N-1 `PREVIOUS`, `retire_previous()` by destroy, and the "retiring does not resurrect" and "only two versions" tests. -4. **Metadata and listing:** `needs_rotation` in `custom_metadata`, including the flag-failure rule; `list_secrets()` with its recursive LIST; the multisite isolation test; and the sealed-or-unreachable test. -5. **AWS Secrets Manager site-scope fix** (deliverable 3), as a separate commit with its own README note. -6. **Documentation and journal.** See §2. Also write `examples/vault-provider/README.md`, with a written answer to each of the four questions, add the example to `examples/README.md`'s table, and add the Vault finding to `docs/journal/proposal-questions.md` question 2.

Carry it into the main repo's config if you want to keep it. - -## What was built - -**Phase 1: examples harness, Vault half (P1-01 to P1-03).** Adds a PHPUnit harness for the examples: `phpunit-examples.xml.dist`, `tests/bootstrap-examples.php`, `make test-examples`, and a CI job named `examples` that runs a Vault dev server as a service container. The Vault image is pinned by digest (`sha256:47f14a6…`, Vault 2.1.1), and that digest is the same in the Makefile, `ci.yml`, and the README. The flight also adds a `Vault_Test_Server` helper that tests use to inspect Vault directly and to wipe everything under `wp/` between tests. This harness is the part the `build/kms-keyring` flight is expected to overlap with. The overlap gets reconciled at merge. - -**Phase 2: Vault provider core (P2-01 to P2-03).** Adds `examples/vault-provider/secrets.php`, a single-file drop-in with no Composer dependencies and no SDK. It defines `Vault_KV2_Provider` and talks to the KV v2 HTTP API through `WP_Http`. It maps paths to `wp/site//` and `wp/network/`. It covers every interface method in its simplest correct form, and the shared conformance suite passes against the live Vault. - -**Phase 3: versions and retirement (P3-01 to P3-02).** Tests against the live server prove two rules. First, "previous" means strictly version N-1, even when older versions still exist. Second, `retire_previous()` destroys that version outright. A soft delete is not enough. - -**Phase 4: metadata and listing (P4-01 to P4-03).** `needs_rotation` is stored in the secret's Vault `custom_metadata`, and `list_secrets()` now returns real metadata. Tests cover three more behaviours: -- Site scope is separate per blog, and network scope is shared across blogs. -- A sealed or unreachable Vault returns a `WP_Error` with code `WP_SECRETS_ERROR_STORE_UNAVAILABLE` from every method. It never reads as "absent". -- The request timeout was measured. - -**Phase 5: AWS site-scope fix (P5-01 to P5-02).** The AWS Secrets Manager example now puts site-scoped secrets under `wp/site//`. It reads the blog id when each call runs, so the name stays correct after `switch_to_blog()`. The fix is tested offline by capturing the outgoing request through `pre_http_request`. The AWS README gains an upgrade walkthrough for renaming existing secrets. - -**Phase 6: documentation and journal (P6-01 to P6-04).** This phase adds: -- The Vault example README, which answers the detailed spec's "four questions". -- ADR 0009, `docs/decisions/0009-cap-a-many-version-backend-to-two-slots.md`. Expect to renumber it at merge. -- "As built" sections for the affected spec pages. -- Updates to the journal tracking pages, plus a new journal entry, `docs/journal/2026-09-24-a-vault-provider.md`. -- Index updates. - -Nothing under `src/`, `plugin/`, or `cli/` changed. - -**Round 1 fixes (R1-01 to R1-03).** -- R1-01: writing the rotation flag now merges with the existing `custom_metadata` instead of replacing it. Before this fix, every set or clear erased every other key in that map. -- R1-02: the test helper now fails loudly when Vault is unreachable, instead of reporting the secret as absent. -- R1-03: doc claims that had drifted from the code were corrected. A new constraint stops Foundry task IDs from appearing in shipped files. - -## Decisions that shaped it - -- **Harness scope (plan).** Only the parts of the harness this flight needs are built: phpunit config, bootstrap, `make test-examples`, the `examples` CI job, and `examples/vault-provider/tests/`. There are no Moto or KMS tests. The KMS flight's copy is reconciled at merge. -- **No interface changes (plan).** No file changed under `src/`, `plugin/`, or `cli/`, not even a docblock. Two findings concern the interface: "previous is strictly N-1", and "a `BOUNDARY_PROVIDER` provider may still need local key material". Both are recorded in `docs/journal/open-questions.md` for the Trac ticket instead of being changed in code. -- **Phases map one to one to SPEC §8 (plan).** -- **Phase 2 lands every method in its simplest form (plan, P2-02).** This keeps the conformance suite passing before phases 3 and 4 finish the semantics. Nothing is stubbed and no test is skipped. Between P2-02 and P4-01, the provider accepted `needs_rotation` without writing it. -- **`REQUEST_TIMEOUT = 5` seconds (plan, P2-01, measured in P4-02).** It is a `⚠️ ASSUMPTION` constant and appears nowhere else as a literal. -- **`MAX_VERSIONS = 2` (plan, P2-01; ADR 0009).** The provider limits Vault to two versions per secret instead of widening the WordPress version model. -- **The flag is cleared by writing `"0"` (plan, P4-01).** The flag counts as set only when the value is exactly `"1"`. The plan's stated reason, that Vault rejects an empty map, turned out to be false; see Spec issues. The choice stands as an encoding. After R1-01, the write also merges with the existing keys. -- **Listing uses `GET …?list=true` (plan, P2-02).** Vault documents it as equivalent to the `LIST` verb. The provider avoids depending on `WP_Http` passing a custom verb through every transport. -- **`$name_prefix` in `list_secrets()` is a namespace (plan, P2-02/P4-01).** This matches the libsodium provider. -- **`wp_secret_changed` fingerprints are `''` (plan, P2-02).** The AWS example does the same. It avoids an extra read, and it is a known limit. -- **In `set()`, the action fires before the flag write (plan, P2-02/P4-01).** If the flag was requested and its write fails, `set()` returns a `WP_Error`, but the audit hook has already seen the change. -- **Fingerprint scope is `'network'`/`'site'` (plan).** This matches the shipped provider. The AWS example's use of `'site'` for network secrets is an existing inconsistency that this flight left alone. -- **The Vault image is pinned by digest (plan, P1-01).** It was pulled from `latest` once. The server reports version 2.1.1. -- **Test server configuration (plan, P1-01).** It comes from `VAULT_ADDR` and `VAULT_TOKEN`. If Vault is unreachable, the tests fail rather than skip. -- **Test isolation (plan, P1-01).** Every Vault test class wipes `wp/` in `set_up()`. -- **Multisite tests (plan, P4-02).** They live in one file that is skipped when the site isn't multisite, and `make test-examples` runs the suite twice. -- **No `extraVerify` (plan).** `make test-examples` can't run on the host, so each task ran the examples suite inside wp-env instead. -- **The AWS provider reads the blog id when each call runs (interpretation, P5-01).** The private `scope_prefix()` never caches it, so the name stays correct after `switch_to_blog()`. -- **The link to ADR 0009 was broken for one commit (interpretation, P6-01).** The plan put the link in the README before P6-02 created the ADR. It works at HEAD. -- **`write_flag()` reuses the `$meta` that `set()` already read (interpretation, R1-01).** It does not fetch the metadata again, because the data write in between does not touch `custom_metadata`. The sequence of reading and then writing is not atomic, and the docblock says so. - -## Assumptions still in play - -| Key | Final default | Status | -|---|---|---| -| `Vault_KV2_Provider::REQUEST_TIMEOUT` | `5` seconds | Measured in P4-02 but not tuned: a refused connection returns in about 0.005s, and a non-routable address takes about 4s, under the limit. The value itself is still a judgment call and has not been tested against a remote Vault over TLS. | -| `Vault_KV2_Provider::MAX_VERSIONS` | `2` | Not an assumption: the detailed spec sets it and ADR 0009 records it. It is listed here because a constraint keeps it defined in one place. | - -## Spec issues - -Suggested edits to `docs/SPEC.md` or the detailed spec (`examples/vault-provider/SPEC.md`): - -- **SPEC §8, phase 2:** "conformance suite green" conflicts with the phase plan, because `retire_previous()` is phase 3 and `list_secrets()` is phase 4. State that phase 2 lands minimal forms of every method. -- **SPEC §7, `extraVerify`:** it is allowed only for existing make targets, but `make test-examples` can't run on the host. Allow a wp-env command, or add a make target that runs the suite inside wp-env. Without one, `foundry_mutate` can't see the examples suite; see Pipeline friction. -- **Detailed spec, "a set without the flag clears it":** say how the flag is cleared: write `"0"`, merge with the existing keys, and treat only `"1"` as set. Do not repeat "Vault rejects an empty map". Vault 2.1.1 accepts both `{}` and `[]`. Round 1 caught this false premise in PLAN.md. -- **Detailed spec, `LIST metadata/...`:** note that `GET …?list=true` is the accepted equivalent. -- **Detailed spec, Vault version:** name the version, or say "pin the digest". The pinned image is 2.1.1. PLAN P1-03's text asked for "a current 1.x release", which was wrong (round 1). -- **Detailed spec, fingerprints:** say what `wp_secret_changed` carries for this provider. It currently carries blank strings. -- **AWS example fingerprint scope:** it uses `'site'` for network secrets, while the shipped provider uses `'network'`. Decide whether a future spec should fix this. -- **`examples/README.md` "Dependencies":** it says each example has its own `composer.json`, but neither does. The text was already out of date, and it was left alone because the KMS flight may edit that page. -- **CI triggers:** the workflow runs only on pushes to `main` and on `pull_request`. Pushing the branch alone does not run CI, so the draft PR is what runs it. -- **`WP_Secrets_Provider::set()` contract:** the provider accepted `needs_rotation` without writing it, but only between P2-02 and P4-01 on this branch.

The flag write erased other `custom_metadata` keys (P4-01). - 2. The test helper reported "unreachable" as "absent" (P1-01). - 3. The unreachable-Vault test did not check the error code (P4-02). - 4. A group of doc and code mismatches, plus task IDs leaking into shipped files (P6-01, P6-03, P1-01, P1-02, P2-02, P4-01). -- **Round 2: APPROVED.** 0 findings and 0 fix tasks. No finding came back from round 1. The approval came with notes that were not queued as work: - - In README question 3, the claim that the flag is "never omitted, because Vault replaces `custom_metadata` wholesale" no longer follows now that the write merges. The real reason is the chosen encoding. The `write_flag()` docblock explanation is also thin. This is a wording issue; every factual claim is correct. - - `Vault_Test_Server::wipe_recursive()` has a non-204 DELETE check with no dedicated test: a mutation that removed it survived. The `Assert::fail()` in `request()` is only covered indirectly, by status checks that catch the same condition. - - The local examples suite still fails intermittently: 2 of 4 runs failed with `cURL error 28` to `host.docker.internal:8201`. This comes from Docker Desktop port forwarding, not the code, and failures now name the URL at the point they happen. CI should not be affected. - - Round 1 notes that still apply: - - The Foundry `.gitignore` change and the `CLAUDE.md`/`docs/SPEC.md` entries that hard-code `--env-cwd=wp-content/plugins/vault-provider` are all Foundry files. Strip them before merge. - - The install block in `secrets.php` leaves `$mount` and `$namespace` as local variables. This is harmless. - -## Pipeline friction - -- **implement, environment-flakiness:** Other Foundry flights (kms-keyring, cli-smoke) ran Docker containers on the same host at the same time. That caused intermittent connection timeouts from wp-env's tests-cli container to `host.docker.internal:8201`, so PHPUnit failed for reasons unrelated to the code. Confirming the cause was environmental took one extra debug-and-rerun cycle. -- **review, mutate-blind-spot:** `foundry_mutate` on `examples/vault-provider/secrets.php` can run only the configured verify commands, and none of them runs the examples suite. So every mutation of the example "survives" after a ~4 minute ci-local run, whatever the tests cover. The reviewer had to apply mutations by hand to a copy inside the container to get a real killed/survived result. -- **summarize, tool-refusal:** The harness refused the `Write` tool for `docs/SUMMARY.md` ("subagents should return findings as text"). The file was written with a shell heredoc instead, as the skill directs. diff --git a/docs/foundry.json b/docs/foundry.json deleted file mode 100644 index f6731d5..0000000 --- a/docs/foundry.json +++ /dev/null @@ -1,217 +0,0 @@ -{ - "verify": [ - { - "cmd": "bin/ci-local.sh --keep", - "timeoutMs": 1800000 - }, - { - "cmd": "make reference-check", - "timeoutMs": 120000 - } - ], - "extraVerify": {}, - "build": [], - "baseBranch": "main", - "branchPrefix": "build/", - "permissionMode": "auto", - "maxRounds": 3, - "maxRoundsHard": 6, - "constraints": [ - { - "id": "no-filters-in-src", - "description": "No apply_filters() anywhere under src/.
