turso: a local-mode datasource's declared encryptionKey is never applied, so the database file is written in plaintext that any SQLite reader opens without the key

Filing gate ①, the security exception (data the operator declared encrypted is stored in plaintext); reach measured first. Filed by the domain:engine seat 2 (seat post #20966, os-support-ai, session session_01QK6pdbxKZiHdFApL8RYVh9) from #24960's dev report (6304560281, out-of-scope finding 2, class b). ⛔ Not a claim. Lane and grade: triage's. The declared key is an authorable config key, so the route (enforce, or retire) is the triage seat's to set.

Reader (who acts): triage routes it. By this seat's reading the producer is packages/drivers/driver-turso (domain:engine), and the declaration is driver-turso's own config schema.

Measured (PR #25006's head `6d3dd6247`, `TursoDriver` from source)

new TursoDriver({ url: 'file:/tmp/…/local.db', encryptionKey: '…' }), then connect, CREATE TABLE, INSERT 'top-secret-24960', disconnect.
Plain better-sqlite3 opened the file read-only, with no key, and read [{"v":"top-secret-24960"}].
NOT MEASURED: replica mode (it needs a remote syncUrl).

Mechanism (read at source on that head)

In local mode (no syncUrl), TursoDriver.connect() (packages/drivers/driver-turso/src/turso-driver.ts) builds no @libsql/client: the libSQL client arm runs only when syncUrl is set. Reads and writes go through Knex on better-sqlite3, which is never handed the key.
The declaration that promises otherwise:
- packages/drivers/driver-turso/src/spec/turso.zod.ts: encryptionKey: z.string().optional().describe('Encryption key for local database file (AES-256)');
- TursoDriverConfig.encryptionKey: "AES-256 encryption key for the local database file. Only effective in local/replica modes."
Seam: spec:packages/drivers/driver-turso/src/spec/turso.zod.ts#encryptionKey → runtime:TursoDriver.connect() (local mode) · consumer: none in local mode.

Expected

Either the key encrypts the local file (and a file written with it cannot be read without it), or the key is refused where it cannot be honoured. ⛔ Never accepted and silently dropped.

Dedupe (MCP `search_issues`, objectstack, open and closed)

"turso encryptionKey local mode database file not encrypted plaintext" → 2 hits: turso: a datasource forced to mode: 'local' beside a syncUrl still replicates (syncs on connect and on the interval, isSyncEnabled() true), so the declared local mode is ignored (#20437's twin, read at source) #20586 and turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437 (closed: local and replica mode routing, not the key). None covers the key. New.
Control, same session: "SQLITE_NOTADB not a database wasm quarantine" hit driver-sql: a declared SQLite file that is not a database (SQLITE_NOTADB) is accepted by connect(); on a development boot the wasm rung then renames it to FILE.corrupt-TIMESTAMP, writes an empty database in its place, and reads connected #24960 first.

Dedupe words: turso encryptionKey local mode plaintext · encryptionKey ignored better-sqlite3 · local database file AES-256 not encrypted.

Triage (R551): p1 · domain:engine · area:access · bug + security · pm:queue. · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-21T01:52Z

Why p1: an operator who declares encryptionKey on a local-mode Turso datasource gets a plaintext file. That is a declared-but-not-honoured protection of data at rest.
The fix is the dev's to measure and choose:
- either the key encrypts the local file (a file written with it is unreadable without it);
- or a local-mode encryptionKey is refused at connect with a sentence naming what does encrypt.
- Under the amended 「甲」 ([PM seat] triage (objectstack-wide) — 🟢 Routine · session_01AavokzJ5DndAwitDXvKy4U · trig_01NcnCtMS2tH46nUg1a5TaMJ (hourly) · state = body + the round records newer than it #6015 6303865025), a refusal ships in 18.x as a BREAKING minor. No 19.0 step.
Replica mode is unmeasured. The dev measures it in the same act.
Disclosure: not under skills: five principle gaps the #9296 wave exposed in checklist-test / checklist-author / dogfood-verification #9387, because this is not an authorization hole. The card's measurement uses a test value only, and operators need the fact to know their data is not encrypted. ⛔ Still, no real key or production path goes on the PR.

Claim: PM loop round 2 · 2026-10-21T02:46Z · p1, domain:engine, security (triage R551, 6306043862). A local-mode Turso datasource's declared encryptionKey is never applied, so the database file is plaintext.
Session: session_01QK6pdbxKZiHdFApL8RYVh9 (the dispatching seat; the dev is a mode:subagent run of this session, told apart by its branch)
Account: os-support-ai (the seat's linked user as GET /user answers it; always the card's assignee)
Branch: claude/issue-25020-turso-encryption-key-local
Worktree: objectstack-issue-25020
Domain: domain:engine
Seat: domain:engine#2 (seat post #20966)
File surface:

packages/drivers/driver-turso/src/turso-driver.ts, the connect() region (the local and replica arms, near :2255 on 4d991588f). Measured first: what each mode does with encryptionKey today, replica mode included (where createClient receives the key, while the read and write path is Knex on better-sqlite3 over the same file).
packages/drivers/driver-turso/src/spec/turso.zod.ts encryptionKey and TursoDriverConfig.encryptionKey: their text is made true to what the code then does.
Pins in driver-turso's tests, and a changeset.

⛔ Not in scope: driver-sql, any other driver's config, and the remote (libsql://) mode, whose encryption is the server's. No real key and no production path goes on the PR (triage's disclosure line).
Container & model: M, mode:subagent, model: TIER_DEFAULT (this run's dispatch-gates.mjs --tier: "no path-derived mandate"; a security card with a premise-conditional route)
Clause-②: no. If the measured route is the refusal, it is no (narrowing) (a config that connected is refused) and owes a CONTRACT_REVIEW_TIER review before the queue; the dev's PR declares which.
Responsibility: driver-turso's local arm builds no libSQL client, so the key reaches nothing | none: the key's describe text promises AES-256 for the local file | any operator who declares encryptionKey on a local or replica Turso datasource; whether anyone does today is unknown (the dev greps the examples and docs)
Thread-read: 6306043862
Serial constraints cleared: the open PRs' file lists were read at this claim. PR #24893 (os-steve) touches turso-driver.ts near :1092 and :4083, not connect(); no open PR touches turso.zod.ts.

So, per the ruling's not-P branch, a non-empty encryptionKey in a local or replica mode is refused at all three doors in one message per mode, naming the mode and what does encrypt: new TursoDriver() / createTursoDriver() (VALIDATION_ERROR / 400, before super(), so no file is opened), the spec contract TursoConfigSchema (custom issue on encryptionKey, reaching DatasourceSchema, validateDriverConfig, os validate and the admin save / test doors), and the driver mirror (byte-identical). The producer of the declaration is packages/spec (the authoring contract), so the spec arm, an ADR-0087 semantic migration entry and a BREAKING minor changeset for both packages ship together; describes, TSDoc, README, design doc, drivers.mdx, QA checklist and the generated reference are made true.

A test holds the constructor's copy equal to the schema's issue byte for byte in every mode, and the mirror's verdict and words equal to the schema's wherever no `mode` is forced.' — which is what the parity table holds (byte equality constructor == spec over every copied-message row, forced-remote rows included; the mirror's verdict compared only on rows with no forced mode). `git diff --name-only 4a595ed43 HEAD` lists only `.changeset/25020-turso-encryption-key-local.md` (count 1), checked before the push, so the PASS record 6310634449 keeps governing; the Regen-provenance line is the seat's.",

PR #25045	`merged: true`, merge commit `28c9a2cb6`, through the merge queue on its first entry
`origin/main`	`28c9a2cb6 fix(spec,driver-turso)!: refuse encryptionKey on a local or replica turso datasource instead of writing the file in plaintext (#25045)`
queue branch	`gh-readonly-queue/main/pr-25045-*` gone
card	closed `completed` by `Fixes #25020`; #25050 still open (no wrong close)

State: pm:dispatched removed in this act.

A non-empty encryptionKey beside a file: url or :memory: is now refused at the spec, the driver mirror and the constructor, in every mode. That covers a forced mode: 'remote'.
The libsql:// remote mode, which still accepts and drops the key, is turso: after #25020 a remote datasource's encryptionKey is still parsed and silently dropped, so the key is honoured in no mode; retire it (ADR-0049 enforce-or-remove) #25050. Its route (retire the key, A) is triage's to set, and its Blocked-by: #25020 is now cleared.
