🟡 Changes recommended
Several confirmed functional and concurrency issues (registry collision behavior, global drain ordering, progress display, Unicode sanitization, and atomic tmp-file races) need to be fixed before this can be safely merged.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Adds a new extensions/history/ feature that persists prompt history across sessions and exposes a searchable TUI selector (/history and ctrl+shift+r) backed by a multi-file JSONL store, tombstones, and transcript seeding/indexing.
Changes:
- Introduces a per-instance JSONL history store with project/global drains, legacy migration, seed bootstrap, deletes, and GC compaction.
- Adds a bottom-anchored TUI overlay with search/filtering, preview pane, scope toggle, keyboard + mouse-wheel interactions.
- Implements transcript scanning + an incremental / background-built index to support session-derived prompt history.

drainGlobalclaims the legacy global seed is the "newest single source", but the code appends it after sorting (sorted.push(globalSeed)), which makes it drain as the oldest source indrainFilesorder. Either the comment is wrong or (more likely) the seed should be included in the sort so recency ordering is consistent.

- Around line 20-24: Update the atomic write helper’s tmpPath generation to use
a unique per-writer name, following the pid-and-time-scoped approach used by
bootstrapProjectSeed, so concurrent writes cannot share a temporary file. Ensure
failed writes clean up their unique temporary file with unlinkSync, and revise
the helper’s doc comment to describe explicit cleanup instead of overwrite-based
cleanup.
In `@extensions/history/index.ts`:
- Around line 134-137: Update sanitizeForDisplay to append the complete Unicode
code point for astral characters instead of only text[i], while retaining the
index advance that skips the low surrogate. Preserve the existing behavior for
BMP characters and ensure both list rows and previews receive intact emoji and
other non-BMP characters.
- Around line 192-195: Update the padding calculation in the rendering method
around truncateToWidth to measure rendered’s visible width after stripping SGR
escape sequences, matching the centered branch’s measurement approach. Keep the
existing Math.max padding behavior so each row still fills the requested
terminal width, including colored rows produced by rebuildListWithWidth.
- Around line 321-328: Update the constructor containing onNotify to remove the
parameter property: declare onNotify as a class field, accept it as a regular
constructor parameter, and assign the parameter to the field inside the
constructor body.
- Around line 941-967: Schedule a single getWriter() invocation with
setImmediate during extension initialization so bootstrapProjectSeed does not
run on the first-prompt path. Retain getWriter’s synchronous fallback for
prompts arriving before the scheduled call, and ensure the initialization
scheduling does not create duplicate bootstrap work.
In `@extensions/history/session-index.ts`:
- Around line 168-172: Update the statSync failure catch branch to remove the
corresponding filePath entry from nextFiles before incrementing dropped, while
retaining the existing carried deletion handling and continue flow.
- Around line 190-195: Restructure the refresh flow around the changed-path
processing loop so it stats candidates and collects changed/new paths before
reading transcripts. Compare that collected count with syncChangedFileLimit,
return the stale deferred result when over budget, and invoke
extractPromptsFromFile only for an in-budget refresh, preserving existing index
and persistence behavior.
In `@extensions/history/store.ts`:
- Around line 558-563: Reorder the migration flow in the function containing
loadSharedHistory so it collects legacy entries, successfully writes the seed,
and only then renames editor-history.json and editor-history.jsonl to their
imported names. Ensure any seed write failure or empty result leaves the legacy
sources untouched for a later retry.
- Around line 365-374: Update sortFilesForDrain and the drainFiles flow to
retain each file’s parsed entries from sorting and pass those entries through to
draining, rather than calling readFileEntries again. Preserve filtering,
ordering, and the global-seed behavior in drainGlobal while ensuring the seed is
parsed once and represented with its entries.
- Around line 787-788: Update the compact filename construction to include
process.pid, matching the uniqueness already present in the temporary filename,
while preserving the existing timestamp-based naming and rename flow.

sanitizeForDisplay drops the low surrogate of every astral character.
Line 135 appends text[i], which is one UTF-16 code unit. For an astral code point the loop is at the high surrogate, so only the high surrogate is appended. Line 137 then advances past the low surrogate. The low surrogate is never emitted.
Every emoji or other non-BMP character in a prompt becomes a lone unpaired high surrogate. sanitizeForDisplay feeds the list rows at Line 463 and the preview at Line 488, so the affected prompts render as a replacement glyph in both places.
Append the whole code point.

Pad by visible width, not by string length.
Line 195 computes the pad from rendered.length. In the non-centered branch rendered is the value returned by truncateToWidth on already-themed text, so it contains SGR escape sequences. Those bytes count toward .length, so width - rendered.length is much smaller than the real deficit and is usually <= 0. No padding is emitted.
The comment at Lines 193-194 states the row must fill the full terminal width so the overlay leaves no ghost characters. That contract fails for every colored row. rebuildListWithWidth colors each entry at Line 467, so all list rows are affected. The centered branch at Line 188 already strips SGR to measure; apply the same measurement here.

🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win
🔎 Supported by static analysis
🌐 Web query:
Does Node.js --experimental-strip-types support TypeScript constructor parameter properties?
💡 Result:
No, Node.js --experimental-strip-types does not support TypeScript constructor parameter properties [1][2][3]. The type stripping feature is designed to only erase inline TypeScript syntax (such as type annotations, interfaces, and type aliases) that can be removed without changing the runtime JavaScript behavior [2][3]. TypeScript features that require JavaScript code generation, including constructor parameter properties, enums, namespaces with runtime code, and import aliases, are not supported by this mechanism [1][2][4]. If you attempt to use them, the code will throw an error [1][3]. For TypeScript features that require transformation, Node.js previously provided an experimental flag called --experimental-transform-types, which was intended to handle such cases [3][4][5]. Note that as of recent Node.js versions (e.g., v26.0.0), this specific flag has been removed [1][6]. If your project relies on features like parameter properties, you should use a dedicated TypeScript transpiler or build tool to compile your code before running it with Node.js [2].

Move history bootstrap out of the first-prompt handler.
before_agent_start reaches getWriter synchronously before appendSessionCapture writes the prompt. bootstrapProjectSeed reads every project .jsonl file and scans matching transcripts synchronously. The 500 limit bounds collected prompts, not file count or file size. A transcript with few eligible prompts can still be read in full. Schedule one getWriter() call with setImmediate when the extension loads, and keep the synchronous fallback for an earlier prompt.

Delete the stale record from nextFiles when statSync fails.
The deletion pass at Lines 154-161 already copied the cached record into nextFiles and added the path to carried. On a statSync failure this branch removes the path from carried and increments dropped, but it leaves nextFiles[filePath] in place. carried is never read after this point, so the delete changes nothing observable.
The persisted index then keeps the prompts of a file that was treated as deleted, and dropped inflates changeCount for a record that was not removed. This contradicts the contract at Lines 137-138. The trigger is a listed file that becomes unreadable or is removed between listSessionFiles and statSync.

The sync budget does not bound open latency; it only skips the persist.
changeCount is evaluated after the loop at Lines 164-188. That loop already called extractPromptsFromFile for every changed and new file, and each call reads and splits the whole transcript. When the count exceeds syncChangedFileLimit, the function discards that work and returns the stale index.
The result is the worst case of both paths: the caller pays the full O(bytes) rescan cost synchronously on the open path, then mergeHistoryEntries (extensions/history/merge-history.ts Lines 66-74) starts a background build that rescans the same files again. The stated goal at Lines 133-136 and Lines 110-113 is bounded open latency, so the current order does not meet it.
Split the pass: stat every candidate first, collect the changed and new paths, compare the total against syncChangedFileLimit, then run extractPromptsFromFile only when the refresh is within budget.

Avoid reading every store file twice per drain.
sortFilesForDrain parses every file to compute fileSortKey, then discards the parsed entries. drainFiles re-reads and re-parses the same files. Each drainProject call reads the whole project store twice. Each drainGlobal call reads every project directory of every project twice.
Both calls run synchronously on the overlay-open path and on every scope toggle (toggleScope in extensions/history/index.ts, Line 561). With the GC thresholds in this file (50 files, 5000 lines per project), the redundant pass doubles the blocking read cost.

Write the seed before you rename the legacy sources.
The function renames editor-history.json at Line 559 and editor-history.jsonl at Line 570. It writes the seed afterwards at Lines 580-585.
Two failure paths lose access to the legacy history:
- If
fs.writeFileSyncorfs.renameSyncat Lines 580-585 throws, the sources are already renamed to.importedand no seed exists.getWriter()inextensions/history/index.ts(Lines 943-947) swallows the throw. The next run passes theexistsSync(seed)gate at Line 545, finds no legacy sources, and migrates nothing. The legacy history is never imported. loadSharedHistoryreturns[]on any read or parse failure. Ifeditor-history.jsonis momentarily unreadable,collectedstays empty, the function returns at Line 576, and the source is already renamed away.

Make the compact filename unique per process.
The temporary name at Line 788 includes process.pid, but the final name at Line 787 uses only Date.now(). Two pi instances in the same project can run session_shutdown compaction in the same millisecond. Both then rename onto the same compact-<ts>.jsonl, and the second rename overwrites the first. Each process then removes its own toMerge set at Line 793. If the two processes enumerated different file sets, the overwritten content is lost.
Add the pid to the final name.

Return a stable key for an existing collision entry.
After a collision, this code stores the old directory under its long hash. Later ensureRegistryEntry calls only inspect data[hash]. They do not find that long-key entry.
For example, registering A, then colliding B, then reopening A moves B again and assigns the short hash back to A. The short mapping flips between projects. Search the registry for an existing cwd before handling the short-hash collision, and return that existing key. Update storage-path consumers to use the returned key if they derive project paths from the registry.

Thanks for the contribution. This PR is too large and combines too many independent risk areas for one effective review, so please split it into smaller PRs before we continue. Suggested sequence:
Each slice should include its own tests and remain independently reviewable. In particular, the persistence, migration, deletion, and compaction behaviors should not land without concurrency and recovery coverage. |
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.

Known pre-existing environmental gate failures unchanged.
…omments Review fixes (Copilot + CodeRabbit on PR Gentleman-Programming#819): - sanitizeForDisplay: astral code points (> 0xFFFF) are re-appended via String.fromCodePoint instead of only the high surrogate at text[i]; emoji and other non-BMP characters no longer lose half their code point in list rows and previews. The low-surrogate skip is retained. - FixedRowText.render: the full-width pad now measures the VISIBLE width (SGR escape sequences stripped), matching the centered branch's measurement; colored list rows previously padded short and could leave ghost characters on overlay dismiss. - Lazy-windowing comment corrected: PRELOAD_BUFFER is 3 (fired in the final 3 loaded rows), not 2 as the stale comment claimed. - Regression pins added for both behavior fixes.
Slice 4/6 of the PR Gentleman-Programming#819 split (maintainer-requested review slices). - load-shared-history (new): v1 shared-history reader, fail-open entry normalization - session-scan (new): transcript JSONL extraction — line-1 admission gate (type/version), text-block extraction, timestamp fallback chain (message-ms -> entry-ISO -> header-ISO -> mtime), prompt length and whitespace rules, one-level encoded-cwd sessions-root scan - store: legacy migration (v1 editor-history.jsonl + pre-v1 editor-history.json -> history-global.jsonl, one-time gate, .imported renames, corrupt-source skip) and project seed bootstrap (transcript scan -> seed.jsonl written ONCE so deletion cannot resurrect, tombstone suppression, cwd matching via encoded sessions dirs) - index.ts: getWriter now runs the upstream init sequence — migrate -> registry -> seed bootstrap -> open instance writer - indexing scope note: upstream's session indexing (session-index.ts + merge-history.ts, ~400 lines) is dead code on the PR branch — zero importers after the store-only drain pivot — and is intentionally absent from this chain (preserved out-of-tree for reference) - tests: 38 new node:test cases (cumulative 148/148): migration one-time gate + .imported renames + corrupt-source skip, seed written-once anti-resurrection + tombstone suppression + regen idempotence, transcript extraction matrix (583-line dev suite preserved), directory scan; tmpdir + fake-cwd fixtures throughout Gates: cumulative scoped history tests 148/148 green. Known pre-existing environmental gate failures unchanged.
…he first-prompt path Review fixes (CodeRabbit on PR Gentleman-Programming#819): - migrateLegacyStores: legacy sources are renamed .imported only AFTER the global seed write succeeds. Previously each source was renamed immediately after reading, so a seed-write failure stranded the collected entries in .imported files with the one-shot seed gate blocking retry — silent data loss. Failure-path test added: a read-only store root makes the seed write throw, sources stay in place, and the retried migration completes and archives them. - promptHistoryExtension: writer init (migrate + registry + seed bootstrap) is scheduled once via setImmediate so the transcript scan never runs on the first-prompt path; prompts arriving before the scheduled init fall back to getWriter()'s synchronous lazy init, whose writerState guard keeps the work single-shot. - Source pin added for the setImmediate scheduling and the retained synchronous fallback.
Slice 5/6 of the PR Gentleman-Programming#819 split (maintainer-requested review slices). - store: scope-delete section — sweepFiles (atomic rewrite per affected file, emptied session files kept so live writers stay functional, never fatal), deleteFromProject, deleteFromGlobal - selector-helpers: deletionActionsFor (pure provenance->actions planner) and loadedCountAfterDelete (backfill window math), completing the helper surface - index.ts: deleteCurrent on the selector exactly as upstream — provenance- planned sweep + tombstone ALWAYS written (seed/transcript-sourced entries cannot resurface; the seed is write-once) + splice + backfill + failure toast; ctrl+shift+backspace dispatch entry and footer affordance restored (dispatch table back to 12 entries) - privacy semantics (enforced by tests): hidden.json fail-open read, tombstone precedes any visibility change, deletion from the global seed and project stores is permanent because the seed is written once - tests: 17 new/updated node:test cases (cumulative 165/165): sweep with a concurrent live writer, emptied-file-kept, chmod-000 partial failure toast path, tombstone-always planner pin, unknown-prompt no-op, backfill bounds, dispatch/wheel table pins restored to 12 Gates: cumulative scoped history tests 165/165 green. Known pre-existing environmental gate failures unchanged.
Slice 6/6 of the PR Gentleman-Programming#819 split (maintainer-requested review slices). - store: GC/compaction section — thresholds (50 files / 5000 lines / keep-newest-10), gcProjectDir entry point, compactFiles (merge all but newest 10 into compact-<ts>.jsonl, atomic write BEFORE originals removed, rm failure tolerated); dead compactProjectDir export (zero callers) dropped — store.ts now carries upstream content minus the documented dead exports - index.ts: session_shutdown handler wired to gcProjectDir (final registration surface: before_agent_start, session_shutdown, tool_call, ctrl+shift+r shortcut, history command) - tests: 9 new node:test cases (cumulative 174/174): threshold no-op below limits, keep-newest-10 untouched, line-threshold trigger, missing-dir and unreadable-file skips, atomic-before-rm ordering, rm-failure tolerance, concurrent append during compaction never loses post-compaction writes; tmpdir fixtures with machine-independent literals throughout Gates: cumulative scoped history tests 174/174 green — the complete six-slice chain. Known pre-existing environmental gate failures unchanged (gitignored contracts/.DS_Store; package-manifest needs node_modules, now installed).
Review fixes (CodeRabbit + Copilot on PR Gentleman-Programming#819): - compactFiles: the compact artifact name now carries process.pid (compact-<pid>-<ts>.jsonl), matching the uniqueness convention of the staging name — two concurrent instances can never target the same compact filename. Filename pin updated accordingly. - session_shutdown comment corrected: compaction runs at the GC thresholds (50 files / 5000 lines / keep-newest-10), not a "1000-line limit" as the stale comment claimed.

Use the shared promptDedupKey in store.ts.
store.ts contains a byte-identical promptDedupKeyOf implementation for tombstone filtering. The hide-file contract requires the merge filter to use the shared key, not a reimplementation. selector-helpers.ts has no runtime dependencies, and store.ts already reaches it through hide-prompts.ts, so this import does not introduce an undesirable dependency or cycle. Two implementations can diverge when the normalization changes.

A delete sweep can drop prompts that another instance appends concurrently.
sweepFiles reads the whole file at Line 430, filters in memory, then renames a rewritten copy over the file at Line 452. The sweep covers every .jsonl file in the project dir, including the live capture files of other running pi instances. If another instance appends a prompt between the read and the rename, the rename discards that line.
The trigger is realistic: two pi instances run in the same project, one user deletes a prompt, and the other instance sends a prompt at the same moment. The consequence is a silently lost history entry.
Restrict the rewrite to files the current process does not expect to be live, or re-check the file size and mtime immediately before the rename and retry when they changed.

Transcript discovery does not canonicalize the cwd, so seeding misses symlinked projects.
projectHash resolves the cwd through fs.realpathSync at Line 31, and the comment at Lines 23-26 states that pi's session manager applies the same resolution. listProjectTranscripts encodes the raw cwd instead. If the user opens the project through a symlink, the encoded directory name does not match the session directory that pi created from the real path. bootstrapProjectSeed then finds no transcripts and seeds nothing, without an error.
Resolve the cwd before encoding it.

Compaction merges the tail newest-file-first, which inverts recency inside the compact file.
filesMtimeDesc is sorted newest first, so toMerge at Line 789 starts with the newest file of the tail. The loop appends its entries first. The doc comment at Lines 771-772 states that the merged content is chronological, but the produced order is reverse-chronological across files.
drainFiles reads a file's entries from the end backward (Line 323). After compaction, the drain therefore returns the oldest tail file's prompts before the newest tail file's prompts. The visible history order changes after every GC run.
Reverse the tail before merging.
🐛 Proposed fix to merge the tail chronologically
- const toMerge = filesMtimeDesc.slice(keepNewest); // oldest tail
+ const toMerge = filesMtimeDesc.slice(keepNewest); // oldest tail, newest-first
+ const mergeOrder = [...toMerge].reverse(); // chronological: oldest file first

Sync 72b5adf faithfully mirrored pi-history main, which never received the review fixes from the slice reviews (PR Gentleman-Programming#819); the sync silently reverted them along with their test pins. Restore everything on the slice-06 PR branch, adapted to the current upstream-parity sources, with the test-hygiene commits (portable fixtures, skip wrappers) already cherry-picked in: - store: compact artifact name is pid-scoped (compact-<pid>-<ts>.jsonl) so two concurrent instances can never rename onto the same file (silent compact loss) - store: migrateLegacyStores renames legacy sources to .imported only AFTER the global seed write succeeds - a failed write no longer strands entries with the one-shot gate blocking retry - store: ensureRegistryEntry returns an existing long-key mapping unchanged so collision assignments stay stable across calls - index: sanitizeForDisplay re-appends astral code points whole (String.fromCodePoint) - emoji no longer lose half their code point - index: FixedRowText.render pads by the SGR-stripped visible width - colored rows no longer fall short and leave ghost characters - index: writer init (migrate/registry/seed) is scheduled via setImmediate so bootstrap never runs on the first-prompt path - index: PRELOAD_BUFFER comment corrected to the constant's real value - tests: restore the GC crash-safety trio (atomic ordering, rm-failure tolerance, active-writer mid-compaction) plus the pid filename pin, the migration retry test, the registry stability test, the setImmediate scheduling pin, and the padding + astral pins - compactProjectDir stays exported for upstream parity (no knip gate configured); gcProjectDir remains the wired and tested entry point Gates: full history suite 196 pass / 0 fail under bun (node:test sources). No tsc/typecheck script exists in this repo; the suite run parses every changed file via node's type stripping.
Fold the slice-06 PR restorations into the feature trunk: the six review fixes clobbered by the upstream sync (pid-scoped compact name, migration rename-after-seed ordering, registry collision stability, astral sanitization, visible-width row padding, setImmediate warm init) plus their restored test pins, and the test-hygiene commits (portable fixtures, skip wrappers) unified with the cherry-picked copies on the PR branch. GC crash-safety tests resolve to the slice-06 versions (trio + pid filename pin). Trees of both branches are identical after this merge.
Take in the remote branch's merge of Gentleman-Programming:main (e6bfeaf) so the trunk carries the reviewed history work on top of current main. Main does not touch extensions/history or the history tests, so the history module is unchanged by this merge.
