feat(history): read, ordering, deduplication, and project/global query APIs (slice 2/6) - #1392
Conversation
Slice 1/6 of the PR Gentleman-Programming#819 split (maintainer-requested review slices). - atomic-write: same-dir tmp+rename JSON writer, concurrent-instance-safe staging names, never throws - store: project identity (realpath+sha256[:16], raw-path fallback, 24-char collision re-key), project/seed/global/registry path derivations, advisory registry with fail-open reads and atomic writes, tolerant JSONL line parser, lazy per-instance session writer with command filtering - extension entry: identity constants and capture-only wiring (before_agent_start -> appendSessionCapture); migration, seeding, selector, deletion, and GC join in later slices - tests: 32 node:test cases covering storage concurrency and recovery (parallel writers, interleaved captures, burst order integrity, torn-line matrix + crash-tail recovery window, rapid same-target atomic writes with zero staging residue, two-instance registry interleaving, collision re-key, corrupt/wrong-shape fail-open) - test vectors are machine-independent: literal cwds exercise the documented raw-string fallback identically on every platform Gates: scoped history tests 32/32 green. verify-package-files and package-manifest failures are pre-existing environmental (gitignored contracts/.DS_Store; missing node_modules) and reproduce on vanilla origin/main.
Review fix (CodeRabbit #5160388228): ensureRegistryEntry now searches the registry for an existing mapping of the incoming cwd before the collision branch, returning the existing short or long key unchanged. Previously, re-entering a cwd that an earlier collision had re-keyed to 24 chars re-triggered the collision and flipped the other occupant's key every time — collision assignments were not stable. Adds a stability test: the re-keyed cwd keeps its long key, the short-hash holder keeps its key, and the registry bytes do not change across re-entries. Note: the atomic-write staging-name race CodeRabbit reported in the original commit was already hardened on this branch (unique .tmp-<pid>-<ts> staging + unlink-on-failure); no further change.
…y APIs Slice 2/6 of the PR Gentleman-Programming#819 split (maintainer-requested review slices). - store: reader/query section — file listing with mtime resolution, drain ordering (newest entry ts, mtime fallback; stable under atomic rewrites), dedup + tombstone filter + cap drain, project scope drain (hash dir) and global scope drain (all project dirs, legacy global seed last); dead generator fileEntriesBackward (zero callers) dropped - hide-prompts: tombstone file contract (fail-open reader, atomic sorted writer, shared dedup key) — lands here because the drain APIs filter hidden prompts via the optional stateDir parameter; slice 5 delivers deletion semantics on top - selector-helpers (new): entry/dedup-key normalization, keep-first read-time dedup, records shaping with provenance, result filter with MAX_RESULTS cap; windowing/nav helpers follow in slice 3 - tests: 21 new node:test cases (cumulative 53/53): drain ordering across mixed mtimes, hidden-prompt filtering incl. corrupt hidden.json fail-open, dedup key normalization, cap at exactly 10000, hide/write contract incl. ENOTDIR failure; portable CWD literals throughout (no machine-specific paths) Gates: cumulative scoped history tests 53/53 green (slice-1 set unchanged). Known pre-existing environmental gate failures unchanged (contracts/.DS_Store; missing node_modules for package-manifest).
Review fix (Copilot suppressed comment, store.ts): the docblock claimed the legacy global seed is the "newest single source", but the code deliberately appends it after sorting (`// legacy last`) so per-project entries win recency and keep-first dedup. Document the actual, intended behavior instead of changing it: migrated legacy history is the least specific source.

Serialize tombstone updates across instances.
If two instances call hidePrompt for different texts in the same stateDir, both can read the same old set. Each atomic rename then succeeds, but the later write removes the other instance’s tombstone. The hidden prompt can reappear. Protect the read-modify-write operation with a lock shared across instances; an atomic rename alone protects only the individual write.

Use writeJsonAtomic for the registry, or clean up the temp file on failure.
writeRegistryAtomic repeats the tmp+rename logic from extensions/history/atomic-write.ts. It has no catch branch that unlinks tmp. If writeFileSync or renameSync fails, for example with ENOSPC or EPERM, a registry.json.tmp-<pid>-<ts> file stays in the store root. This happens again on every startup because extensions/history/index.ts calls ensureRegistryEntry once per load. Based on learnings: temp files "must clean them up deterministically".

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Registry identity uses the raw cwd, but projectHash uses the realpath.
projectHash resolves cwd with realpathSync, so /real and a symlink /link produce the same hash. data[hash] === cwd and the existingKey lookup compare raw strings. This causes the following sequence:
ensureRegistryEntry(root, "/real")storesdata[H] = "/real".ensureRegistryEntry(root, "/link")finds no raw match and takes the collision branch at Line 123. It moves"/real"to a 24-char key and setsdata[H] = "/link".- Later calls with
"/real"return the 24-char key.projectDirnever uses that key.
As a result, one project identity gets a false collision entry and a return value that does not match its data directory. This breaks the documented contract that symlinked paths "merge into a single identity". Canonicalize cwd once and use the canonical value for both the comparison and the stored value.
🐛 Proposed fix
export function ensureRegistryEntry(
root: string,
cwd: string,
): RegistryEntryResult {
- const hash = projectHash(cwd);
+ let canonical = cwd;
+ try {
+ canonical = fs.realpathSync(cwd);
+ } catch {
+ // fall back to the raw path, same as projectHash
+ }
+ const hash = projectHash(canonical);
const data = readRegistry(root);
- if (data[hash] === cwd) return { hash, created: false };
+ if (data[hash] === canonical) return { hash, created: false };
...
- const existingKey = Object.keys(data).find((k) => data[k] === cwd);
+ const existingKey = Object.keys(data).find((k) => data[k] === canonical);Use canonical in place of cwd in the remaining assignments too.

🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win
Every drain reads and parses each JSONL file twice.
sortFilesForDrain calls readFileEntries on every file to compute the sort key. It then keeps only the file paths. drainFiles calls readFileEntries again on each file. drainGlobal covers all projects, so it reads and parses the full history twice before it can stop at limit. Two more costs add to this:
listProjectFilessorts withfileMtimeMsinside the comparator. This makes O(n log n)statSynccalls, andsortFilesForDraindiscards that order.- The docstrings of
drainProjectanddrainGlobalsay "mtime-newest-first", but the sort key is the newesttsin the file.
Return the parsed entries from the sort step and drain those entries.

Review follow-up on the slice-01 PR: the before_agent_start handler recorded delivered prompts by default while the deletion UI is still unshipped, so an intermediate release could accumulate sensitive prompts with no removal path. - Capture is now strictly opt-in via GENTLE_PI_HISTORY_CAPTURE=1|true|on (default off); the switch doubles as the disable path, is checked per prompt, and a disabled session writes nothing - no registry entry, no files. - promptHistoryExtension takes injectable deps (env/root/cwd/ instanceId/now) with one writer closure per extension load. - New tests: strict opt-in matrix, default-off inertness, opted-in capture, disable-leaves-existing-files. - docs/prompt-history.md documents the switch, storage locations, permissions/readers, and disable/removal semantics; the README docs table gains a pointer.
Resolves PR Gentleman-Programming#1390's README.md conflict: main's 3.5 documentation restructure replaced the former docs table; the prompt-history row is re-applied in the new Destination/Purpose shape. No other conflicts; all other upstream changes auto-merged.
A corrupt or unreadable hide file previously loaded as an empty hidden set (fail open), resurfacing prompts the user may have hidden because they contain secrets. The next hide also rewrote the file clean, silently clearing the incident. - readHiddenPrompts replaces loadHiddenPrompts: ENOENT stays trusted-empty (nothing ever hidden); any other read error, JSON parse failure, or non-array shape is untrusted (unreadable/corrupt/ malformed) and carries a recovery message naming hidden.json - hidePrompt refuses to write over an untrusted file: recovery is the explicit delete-or-restore of hidden.json, never a silent rewrite - drainProject/drainGlobal return DrainResult: untrusted tombstones block the drain (status "blocked", no prompts field) so the future selector UI must surface the warning; no stateDir keeps raw drain semantics Tests: rewrite T26 to pin the refusal + byte-unchanged file + manual unlink recovery; add malformed-shape, junk-item tolerance, and chmod 000 unreadable cases; drains pin the blocked shape (no prompts field) and the missing-file-stays-ok case.

Serialize the entire hidePrompt update.
When two instances call hidePrompt for the same stateDir, both can read the same trusted set and then write different updates. writeJsonAtomic makes each rename atomic, but it does not serialize the read-modify-write sequence. The later rename can therefore remove the earlier key.
Re-reading before the rename does not prevent this race because both calls can still read before either rename. Use one shared exclusive lock for the complete read/add/write sequence, with stale-lock handling.

Use the shared promptDedupKey in the tombstone filter.
The current local helper returns the same value, but it violates the contract that tombstone keys must use the shared implementation. Import promptDedupKey and remove the local copy so future changes cannot make valid hidden keys fail to match.

Merges feat/history-slice-01-store (31e7d50) into the slice-02 branch so the PR diff against main shows only slice-2's own delta: the branch now contains slice-1's review fix (84c1232, opt-in capture) and the upstream main sync (31e7d50), closing the stale-stack gap where a future main comparison would have shown those changes reverted.

Correct the no-restart disable instruction.
A shell change to GENTLE_PI_HISTORY_CAPTURE does not change the environment of an already-running Pi process. The handler rechecks its own process.env on each prompt, but the documented shell invocation provides no in-process way to unset it. Tell users to restart Pi with capture disabled, or document a working in-process control. (nodejs.org)

Make the project-removal command executable.
In a shell, <hash> is parsed as redirection syntax rather than as a placeholder in the path. The command fails, leaving that project’s stored prompts in place. Use a shell-safe placeholder and tell the user to replace it with the registry hash.

Warn when opt-in history capture fails.
If the store remains unwritable, each later prompt retries the same failing append and is silently omitted from history. Keep the agent loop running, but use the before_agent_start context's ui.notify when ctx.hasUI is true, and rate-limit the warning. This is a minor history-reliability issue, not persisted-data corruption.

Thanks for the suggestion — agreed that per-slice diff targeting is the right review experience for this chain. We tried to set it up from the fork side and hit a GitHub constraint: a PR base branch must exist in the base repository, and In the meantime we synced this branch to slice-1's tip (ecf148b → 31e7d50): it carries slice-1's review fix and current If a maintainer pushes |
The history slice branches must not touch README.md: the docs table lives in main and evolves independently of the extension slices. The opt-in capture documentation stays in docs/prompt-history.md; the README pointer row introduced by the capture-gate commit is dropped and README.md is restored to upstream/main verbatim.

Port slice-5's restoration (89ac348) of the fail-closed tombstone contract onto slice-4 so PR Gentleman-Programming#1391 does not reintroduce the fail-open hidden.json behavior after Gentleman-Programming#1392 merges: - hide-prompts.ts byte-identical to the restored version: readHiddenPrompts returns trusted (missing/valid array) or untrusted (unreadable/corrupt/malformed) with a recovery message naming hidden.json; hidePrompt refuses to rewrite an untrusted file. - store.ts: drains return DrainResult (blocked status carries no prompts field) and bootstrapProjectSeed skips seeding on untrusted tombstones. - index.ts: drainForScope unwraps DrainResult; the selector surfaces the blocked recovery message instead of silently showing entries. - Tests: hide-prompts, drain-hidden, and drain-order suites ported byte-identically from the restored versions. Delete-flow code remains slice-5 scope; nothing delete-related entered this port.

Summary
Stacking note: this branch sits on top of slice 1 (#1390) and is synced to its tip (merge ecf148b — carries slice-1's review fix and current
main, so nothing here can revert slice-1 changes at merge time). The PR base ismain, so until #1390 merges the diff below includes slice 1's files; once #1390 merges it shrinks to slice 2's own delta: 8 files, +1036/−6. (Targeting this PR at the slice-1 branch — so reviewers would see only slice-2's delta pre-merge — needs that branch to exist in this repo; the fork owner has no push access, so a maintainer would need to create it.)Changes (slice's own delta)
