feat(history): tombstones, deletion, and privacy semantics (slice 5/6) - #1393
Alan-TheGentleman merged 11 commits into
Conversation
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.

extensions/history/index.ts imported `ShortcutContext`, a type that only exists in the dev repo's @types shim — the real @earendil-works/pi-coding-agent exports `ExtensionCommandContext`, so the type gate added to main reports TS2305 on this branch's CI merge. Import `ExtensionCommandContext` and narrow both handler contexts to `Pick<ExtensionCommandContext, "ui">` (the only member they use), mirroring the fix already carried on the slice-6 branch.

Please make the delete affordance explicit about its scope: the proposed tombstone hides a session-derived prompt from this history index and prevents re-seeding, but it does not erase the original Pi transcript or any other stored copy. The user-facing help/confirmation should distinguish "hide from history" from "delete stored prompt" and say what happens if a store rewrite or hide-file write fails. This is especially important for someone deleting a prompt because it contained a secret. |
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.

| Slice 1 of the prompt-history extension (#819 split) ships the storage layer only: | ||
| a per-instance JSONL capture store, project identity, and the read/write | ||
| primitives later slices build on. The selector UI, deletion/scope drains, and GC | ||
| arrive in later slices of the chain. | ||
|
|
||
| ## Capture is opt-in | ||
|
|
||
| Recording is **off by default**. Delivered prompts can contain secrets, and the | ||
| deletion UI is not shipped yet, so nothing is stored unless you explicitly opt in: | ||
|
|
||
| ```bash | ||
| GENTLE_PI_HISTORY_CAPTURE=1 pi | ||
| ``` | ||
|
|
||
| - Enabled by `1`, `true`, or `on` (case-insensitive). Unset, empty, or any other | ||
| value means **off** — the same switch is the disable path. | ||
| - The check runs per prompt: unsetting the switch (or setting it to `0`) stops | ||
| new captures immediately, no pi restart needed. | ||
| - With capture off the extension is inert: no registry entry, no files, and | ||
| prompts are never written. | ||
|
|
||
| ## Where the files live | ||
|
|
||
| Everything sits under `~/.pi/agent/history/`: | ||
|
|
||
| - `registry.json` — advisory map of project hash → cwd, used for display | ||
| labels. | ||
| - `projects/<hash>/<instance>.jsonl` — one append-only capture file per pi | ||
| process. | ||
|
|
||
| `<hash>` is the first 16 hex chars of the SHA-256 of the canonicalized project | ||
| cwd; `<instance>` is a per-process UUID. Each line is one delivered prompt: | ||
|
|
||
| ```json | ||
| {"v":1,"text":"the prompt as delivered","ts":1700000000000} | ||
| ``` | ||
|
|
||
| UI command-like prompts (`/name ...`) and empty lines are never stored. Later | ||
| slices add the rebuildable `seed.jsonl`, scope drains/deletes, and GC. | ||
|
|
||
| ## Who can read them | ||
|
|
||
| The store is plain JSONL on your local disk, not encrypted. Files are created by | ||
| the pi process with default umask permissions (typically `0644` files inside | ||
| `0755` directories), so any process running as your OS user can read them, and | ||
| other local accounts can too wherever they can traverse your home directory. | ||
| Treat the store as sensitive: it holds your prompts verbatim. | ||
|
|
||
| ## What disabling capture does | ||
|
|
||
| Turning the switch off only stops **new** captures. Nothing is deleted: files | ||
| already written — and the registry entry — stay on disk until you remove them or | ||
| the deletion UI ships. To erase the store manually while capture is off (or pi | ||
| is not running): | ||
|
|
||
| ```bash | ||
| rm -rf ~/.pi/agent/history # whole store | ||
| rm -rf ~/.pi/agent/history/projects/<hash> # one project (see registry.json) | ||
| ``` |

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Stop one delete from hiding unrelated prompts that share a 120-char prefix.
hidePrompt stores promptDedupKey(text). That key is the whitespace-collapsed, lowercased first 120 characters. drainFiles (extensions/history/store.ts Line 337) and bootstrapProjectSeed (extensions/history/store.ts Line 650) drop every entry whose key is in hidden.json.
Assume two distinct prompts share a long preamble, such as a template or a pasted context block. A delete of one of them has these effects:
sweepFilesphysically removes only the exactpromptKeymatch. The sibling stays on disk.- The tombstone hides the sibling in both scopes and blocks it from seeding.
- The user cannot recover the sibling except by editing
hidden.json.
The reverse case is also a problem. dedupePromptEntries already collapses such siblings in the selector, so the user never sees the second prompt before it disappears.
Use the full normalized text as the tombstone key. If the file must stay small, use a hash of the full normalized text. Keep the 120-char key only for display dedup.
🛠️ Proposed direction
- keys.add(promptDedupKey(text));
+ keys.add(promptTombstoneKey(text)); // full normalized text (or its sha256)Apply the same key function in drainFiles and bootstrapProjectSeed instead of promptDedupKeyOf.

Gate selector initialization on captureEnabled. openHistorySelector is reachable from /history and ctrl+shift+r without this check. Its drainForScope call invokes the module-level getWriter, which runs migration, registry creation, and transcript seeding. With capture disabled, this writes history files and can rename legacy files to .imported, contrary to the local opt-in contract. This is a local privacy and data-handling violation, not a critical exploitable security-boundary bypass, because the source transcripts already exist in plaintext on the same local disk.
Remove the duplicate module-level writer and pass the injected paths into the selector. Ensure deleteCurrent also uses the injected root and cwd.

Inject every filesystem root through HistoryDeps, so tests cannot modify the real ~/.pi/agent.
HistoryDeps injects root only. The closure getWriter (Lines 1032-1058) still uses the module constants AGENT_DIR, SESSIONS_ROOT, and PI_HISTORY_NAV_STATE_DIR.
In tests/history-session-writer.test.ts, the opted-in tests (Lines 168-187) call the capture handler with a temp root. That call runs migrateLegacyStores(tempRoot, AGENT_DIR), and the function reads and renames the developer's real ~/.pi/agent/editor-history.jsonl and ~/.pi/agent/editor-history.json to .imported. The same call also scans the real ~/.pi/agent/sessions into the temp seed.
The test at Lines 114-146 calls promptHistoryExtension(pi) with env = process.env. If the developer exports GENTLE_PI_HISTORY_CAPTURE=1, the setImmediate warm-up writes into the real store.
Fix both paths:
- Add
agentDir,sessionsRoot, andstateDirtoHistoryDepsand use them ingetWriter. - In the tests, pass an explicit empty
env, and pass temp paths for all of the directories above.

Prevent a global or project sweep from losing concurrent captures.
sweepFiles reads each <instance>.jsonl and writes a filtered copy. It then renames the copy over the original. Other pi instances append to their own files with appendFileSync at any time.
If instance B appends a prompt after instance A reads B's file and before A renames the copy, the rename discards B's line. The test at tests/history-scope-delete.test.ts Lines 148-163 covers only a writer in the same process that appends after the sweep. It does not cover this window.
The design comment says instance files have "zero shared writes". Scope delete breaks that invariant. Choose one of these fixes:
- Record the file size at read time. Before the rename, re-stat the file. If it grew, re-read and re-filter it.
- Leave other instances' files unchanged and rely on the tombstone alone. Then compact the files during slice-6 GC.

Handle rewrite failures in sweepFiles.
fs.writeFileSync(tmp, …) and fs.renameSync(tmp, file) have no error handling. Examples of failure: a read-only project dir, a full disk, or EPERM on Windows. In each case the exception leaves sweepFiles and passes through deleteFromProject/deleteFromGlobal.
deleteCurrent in extensions/history/index.ts (Lines 577-580) does not catch it. The exception then leaves handleInput, so tui.requestRender() never runs and the user gets no toast.
The failure has three more effects:
- The
.tmp-<pid>-<ts>file is left on disk. It holds a copy of the prompts. - Files earlier in the loop are already rewritten, so the delete is partial.
- The PR's failure-toast contract covers only the hide-file write, not the store rewrite.
Use writeJsonAtomic-style cleanup. Report the failure to the caller so deleteCurrent can notify the user.
🛠️ Proposed fix
- const tmp = `${file}.tmp-${process.pid}-${Date.now()}`;
- fs.writeFileSync(tmp, kept.length > 0 ? kept.join("\n") + "\n" : "", "utf8");
- fs.renameSync(tmp, file);
+ const tmp = `${file}.tmp-${process.pid}-${Date.now()}`;
+ try {
+ fs.writeFileSync(tmp, kept.length > 0 ? kept.join("\n") + "\n" : "", "utf8");
+ fs.renameSync(tmp, file);
+ } catch {
+ try { fs.unlinkSync(tmp); } catch { /* not created */ }
+ failed += 1;
+ continue;
+ }Add failed to SweepResult. In deleteCurrent, call this.onNotify?.(…, "error") when failed > 0.

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.

Review follow-up on the slice-05 PR (plus restoration of a fix clobbered by the Sept-24 merge train): - Restore the fail-closed tombstone contract from slice-2: hidden.json reads return trusted (missing/valid array) or untrusted (unreadable/ corrupt/malformed) with a recovery message naming the file; hidePrompt refuses to silently rewrite an untrusted file; drains return a blocked DrainResult with no prompts field; seed bootstrap fails closed on untrusted tombstones. - Two-step delete confirmation: the first ctrl+shift+backspace arms the selected row with scope-aware copy, the second executes, any other key disarms. The copy distinguishes deleting a stored prompt (physical store removal + tombstone) from hiding a session-derived prompt (tombstone only; transcripts are immutable). - Failure semantics made explicit: store-delete failures toast and abort before any tombstone write; hide failures toast distinctly (session path aborts; editor path reports the store row was removed while the hide failed). - docs/prompt-history.md: "Delete vs hide" section covering provenance semantics, failure behavior, and corrupt-hidden.json recovery. - Tests: restore the fail-closed hide/drain suites, adapt drain-order to the DrainResult contract, and add history-delete-confirm covering arming, provenance, and failure paths.

…_HISTORY_ENABLE, hidden.json cap Rework of the delete affordance per the slice-5 review decisions: - Two-step modal: ctrl+shift+backspace arms the selected row with the footer copy; while armed ONLY y/Y (execute), n/N and Esc (cancel) are honored — every other key is swallowed and stays armed, so nothing is ever typed into the search input. Esc while armed cancels the confirmation without closing the overlay. Wheel still disarms then scrolls. - Session-derived rows are read-only: the delete key on a session row is a silent no-op — session transcripts are immutable input owned by Pi core, so no hide, no tombstone, no store write comes from them. - Confirm copy: "Delete this prompt from history (y/n)? Prompt stays in session log" (single variant; the per-provenance distinction lives in docs/prompt-history.md). - Env rename: GENTLE_PI_HISTORY_CAPTURE → GENTLE_PI_HISTORY_ENABLE (captureEnabled, open-flow warning, docs, tests). - hidden.json retention: capped at HIDE_FILE_MAX_ENTRIES = 1000 in insertion order (newest last) — re-hiding refreshes recency, past the cap the oldest entries drop; .sort() removed; the fail-closed reader is unchanged, so the tombstone still applies to seeded copies and no prompt is permanently fixed. - docs/prompt-history.md: §Delete rewritten (modal, read-only session rows, verbatim failure toasts, cap); env renamed across all sections; stale "deletion UI is not shipped yet" sentences fixed.

Session log is read-only, so the hidden option is not needed: the extension never writes to or deletes from Pi session transcripts — only editor-store prompts are deletable (session-derived rows are read-only in the selector). |
