It is a proposed Apple-silicon macOS follow-up, not a shipped migration or a verified signed-app release. It does not change Clay's branches. The law change in `LAWS/MEMORY.md` is **proposed for product review**: the base law requires directly readable plaintext files, whereas this implementation makes active memory editable in Berd and portable through explicit Markdown import/export. Review and approval of that change is a prerequisite to release, not a consequence of a passing test suite. + +## Boundary + +- The shared `berd-memory` crate encrypts active `me.md`, topic documents, pending and dismissed proposal queues, and approval metadata with AES-256-GCM. The app and the MCP sidecar use the same store and key. The app alone initializes a fresh store; the sidecar never creates or replaces a key. An unavailable or missing key fails closed, without plaintext fallback. +- The first supported target is `aarch64-apple-darwin`. The native command and storage gates, managed MCP registration, renderer availability, sidecar staging, and effective bundle list must agree. Other targets must not bundle or use Berd memory. They cannot prevent a separately installed third-party tool or an older Berd binary from touching files. +- The user reads and edits through Berd. Import reads **one selected Markdown document into an unsaved draft** for review; export writes **one selected document as plaintext**. Neither operation migrates a complete legacy store. Files under `~/.me/` are ciphertext after this implementation initializes that directory, despite their `.md` or `.jsonl` names. Existing tools must not edit them as plaintext. Topic filenames, sizes, timestamps, format markers and `policy.json` remain visible. This is not a secrets vault: other processes running as the user may access the key or decrypted process data. Exports, pre-existing backups, agent transcripts, and model/provider retention are outside the encryption boundary. +- Remembering requires an explicitly enabled policy. When memory is off or the key is unavailable, recall and new proposals are blocked; disabling memory does not delete stored records or erase already-delivered context from a transcript. A reviewed save compares against the document version the person saw, then commits approval and exact removed-line suppression with the encrypted document; a conflicting revision rejects the save rather than guessing consent. + +## Known release decisions — not implemented here + +1. **Legacy `~/.me/` data.** The store refuses a nonempty plaintext directory. It does not migrate documents, pending proposals, declined/removed-memory suppression, approvals, or policy. Starting a new encrypted root without carrying this state could re-propose declined memory. Decide the migration and interruption/recovery contract before turning this on for people who already have memory. +2. **Same-root downgrade/coexistence.** Older Berd builds and other me.md hosts do not honor this store marker or lock and can overwrite ciphertext with plaintext. A version restriction, a separate root with a complete migration plan, or an explicitly accepted rollout limitation is needed. A different root would avoid collisions but does **not** by itself move consent or suppression state. +3. **App/sidecar Keychain behavior.** Both executables use the same service/account via legacy macOS generic-password Keychain operations. Sharing a service/account does not prove a signed sidecar can open an app-created item without prompts. No broker has been selected; a broker would add IPC authorization and lifecycle work. No native Keychain acceptance is claimed from injected-key tests. +4. **Key recovery and transfer.** The original key is needed to read an encrypted backup; a ciphertext-only backup is insufficient. There is no recovery key, machine transfer, destructive reset, authenticated-snapshot rollback detection, or deadline/cancellation for a native credential prompt. Choose what must exist for rollout, and document accepted limits. + +## Validation and acceptance + +Unit tests use temporary directories, `MemoryStore::with_key`, and a fake key provider; they do not access the user's Keychain. They cover initialization and retry, missing/wrong keys, corruption and swaps, journal replay, approval and queue consistency, reviewed-save conflict, and policy-off behavior. A compile and packaging check cannot establish native macOS credential authorization. + +Before anyone calls this shippable, the release owner should run signed app **and** bundled sidecar in an isolated account or VM using synthetic content: initialize; recall approved but not pending content; relaunch and upgrade; deny/cancel and make Keychain unavailable; verify no replacement key, no plaintext fallback, and a responsive off switch. Validate supported-target bundle contents and unsupported-target absence. If the storage/key-custody design changes, rerun that matrix. Do not use a publishing release workflow as a signing probe. No Keychain access or signing is required for code review of this candidate. + +## Review path + +Keep storage, approval/forgetting semantics, app readers/writers, MCP access and target gating together on one branch so no partial commit is independently deployed. The Sherpa cache repair is unrelated and excluded. Clay can review this as a follow-up to #290 or distribute hunks across #288–#290 once the whole integrated behavior is verified. A separate benchmark can follow Buzz's retrieval-test design (seed similar memories, ask without leaking the answer, grade recall and policy-off behavior); it is not evidence of native Keychain acceptance. diff --git a/justfile b/justfile index 93140bc10..06b0af152 100644 --- a/justfile +++ b/justfile @@ -189,6 +189,7 @@ clippy: _clippy-unix: just _tauri-cargo-unix clippy -- -D warnings just _tauri-cargo-unix clippy --features {{ app_features }} -- -D warnings + just _tauri-cargo-unix clippy -p berd-memory --all-targets -- -D warnings just _tauri-cargo-unix clippy -p berdctl -- -D warnings just _tauri-cargo-unix clippy -p tauri-plugin-berdctl --features server -- -D warnings @@ -196,6 +197,7 @@ _clippy-unix: _clippy-windows: just _tauri-cargo-windows clippy -- -D warnings just _tauri-cargo-windows clippy --features {{ app_features }} -- -D warnings + just _tauri-cargo-windows clippy -p berd-memory --all-targets -- -D warnings just _tauri-cargo-windows clippy -p berdctl -- -D warnings just _tauri-cargo-windows clippy -p tauri-plugin-berdctl --features server -- -D warnings @@ -241,6 +243,7 @@ _tauri-test-unix: if [ "$(uname -s)" = "Linux" ];

+1,21 @@ +# Berd encrypted memory crate + +This crate implements the proposed encrypted store shared by Berd and its memory MCP sidecar. The desktop command/storage integration is supported only on Apple-silicon macOS (`aarch64-apple-darwin`). The main app calls `MemoryStore::initialize` explicitly; the sidecar calls `MemoryStore::open` and never creates or replaces a key. `MemoryStore::with_key` is for isolated tests and never accesses Keychain. See [the design and unresolved release decisions](../../../docs/memory-encryption.md). + +## Storage contract + +Encrypted logical records are `me.md`, `topics/*.md`, `proposals/pending.jsonl`, `proposals/dismissed.jsonl`, and `.approved-content.json`. The extensions do **not** indicate plaintext files. The OS key is outside renderer IPC, agent arguments, and environment variables. Authenticated encryption binds ciphertext to the store identifier, record kind and relative path; write temporaries and the recovery journal contain ciphertext only. Filenames, sizes, timestamps, format markers, and `policy.json` are visible. + +- `open(&Path)` requires an established marker and existing key; missing, invalid, or unavailable keys cannot replace a store. `initialize(&Path)` starts an empty store or resumes an interrupted initialization only when its marker and key match. Neither accepts legacy plaintext as an empty store. +- `read`, `write`, `records`, and approval methods use logical relative paths; callers hold `store.lock()` across reads and mutations. Store methods do not reacquire the lock. `lock()` finishes an authenticated pending transaction before returning; after a transaction error, release and reacquire the lock for recovery before continuing. +- `commit_records` and `commit_reviewed_document` use an encrypted bounded journal so a reviewed document, its approval digest, and the complete dismissed/suppression queue recover together. Pending-proposal removal is a final idempotent caller step. Corrupt or conflicting journals block access instead of silently resetting data. This is consistency for cooperating locked readers, not a filesystem-wide atomic rename. +- `policy_enabled` checks separate non-sensitive `policy.json` and fails closed on malformed data. Policy writes use the directory lock without needing Keychain. Key lookup does not hold this transaction/policy lock; initialization uses a separate persistent lock, and established opens revalidate identity and markers after Keychain returns. App memory commands offload blocking key calls to bounded workers so the off switch is not starved by a pending credential prompt. Native OS calls themselves have no deadline or cancellation. +- The key service/account is `com.block.berd.memory.active.v1` / `active-store-`. Same service/account is **not** proof of signed app/sidecar authorization. No recovery key or automatic plaintext migration exists; see the design doc before enabling this for an existing store. + +Capability-relative no-follow access protects roots, parents, files, journal and locks from symlink swaps. Authenticated bytes reject wrong keys, tampering, truncation, record swaps and cross-store reuse. The format does not detect rollback of a whole authenticated snapshot. Older plaintext writers are outside this protocol and may damage the same-root store. + +## Tests + +After activating Hermit, run `cargo test -p berd-memory` and `cargo clippy -p berd-memory --all-targets -- -D warnings` from `src-tauri/`. Unit tests use temporary roots and injected keys/fake providers, not real Keychain. Test coverage includes partial initialization and retry, policy-off during blocked lookups, multi-record transaction recovery, permissions and paths, legacy refusal, encrypted queues/approvals, and MCP recall-policy enforcement. A subprocess test exercises the production stdio executable only with an isolated HOME and missing marker, before Keychain access. + +These tests are not a substitute for a signed app + bundled sidecar acceptance run on an isolated macOS account. The review candidate deliberately does not include the former `portable-store` feature, Windows/Linux native credential support, or portability-test claims. diff --git a/src-tauri/crates/berd-memory/src/lib.rs b/src-tauri/crates/berd-memory/src/lib.rs index 3adc0de6f..2657dfc95 100644 --- a/src-tauri/crates/berd-memory/src/lib.rs +++ b/src-tauri/crates/berd-memory/src/lib.rs @@ -1,98 +1,39 @@ +#![cfg_attr( + not(all(target_os = "macos", target_arch = "aarch64")), + doc = "Native storage is absent on unsupported targets. + +```compile_fail +use berd_memory::store::MemoryStore; +``` + +Home discovery is absent too. + +```compile_fail +use berd_memory::memory_root; +```" +)] + +#[cfg(all(target_os = "macos", target_arch = "aarch64"))] +pub mod store; + use serde_json::Value; use sha2::{Digest, Sha256}; +#[cfg(all(target_os = "macos", target_arch = "aarch64"))] +use std::path::PathBuf; +use std::time::{SystemTime, UNIX_EPOCH}; use unicode_general_category::{get_general_category, GeneralCategory}; use unicode_normalization::UnicodeNormalization; -use std::collections::BTreeMap; -use std::fs::{self, OpenOptions}; -use std::io::{ErrorKind, Write}; -use std::path::{Path, PathBuf}; -use std::thread; -use std::time::{Duration, Instant, SystemTime, UNIX_EPOCH}; pub const PENDING_FILE: &str = "pending.jsonl"; pub const DISMISSED_FILE: &str = "dismissed.jsonl"; -const APPROVED_CONTENT_FILE: &str = ".approved-content.json"; +#[cfg(all(target_os = "macos", target_arch = "aarch64"))] pub fn memory_root() -> Result { dirs::home_dir() .map(|home| home.join(".me")) .ok_or_else(|| "No home directory".to_string()) } -fn approved_key(root: &Path, target: &Path) -> Result { - target - .strip_prefix(root) - .map(|path| path.to_string_lossy().replace('\\', "/")) - .map_err(|_| "Memory path escaped the store".to_string()) -} - -fn content_hash(contents: &str) -> String { - hex::encode(Sha256::digest(contents.as_bytes())) -} - -fn approved_manifest(root: &Path) -> Option> { - let contents = fs::read_to_string(root.join(APPROVED_CONTENT_FILE)).ok()?; - serde_json::from_str(&contents).ok() -} - -/// Mark one exact document version as approved.
