From d5b83af39140817dbea628793c456340c35c9515 Mon Sep 17 00:00:00 2001 From: Milla J <232237854+milla-jovovich@users.noreply.github.com> Date: Mon, 25 May 2026 20:06:04 -0700 Subject: [PATCH 1/5] =?UTF-8?q?fix(ingest):=20make=20all=204=20miners=20ad?= =?UTF-8?q?ditive=20=E2=80=94=20verbatim=20history=20never=20destroyed=20(?= =?UTF-8?q?#1593,=20#1580)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Re-mining a source file used to silently destroy every prior drawer for that file via collection.delete(where=source_file) before re-inserting fresh chunks. That delete was a chromadb 0.6.3 upsert-bug workaround that accidentally became destructive-overwrite semantics — the most severe possible defect for a system whose stated purpose is verbatim preservation across decades. This PR makes all four miner write paths (miner.py, format_miner.py, diary_ingest.py, convo_miner.py) purely additive: re-mining a source file INSERTS new drawer rows alongside any existing ones rather than overwriting them. The only path to drawer destruction is the new explicit `mempalace delete` verb. The user story (from #1593 — Aya's words): "there is a difference between someone fixing typos and someone scrapping a document because they thought it sucked or it was embarrassing at the time, but then years later you would go, wow i wish i could look at that now, with a new set of eyes and remember who I was then, or that idea that seemed stupid actually was really relevant now... and it would be there." Mechanism: - drawer_id formula now includes `filed_at` so each mining pass produces unique IDs; the upsert path inserts instead of overwrites. - Three new metadata fields on every drawer: parent_drawer_id — groups every chunk of one mining pass (searcher scope key; closes #1580 by giving the neighbor expansion a real boundary). stack_id — groups every VERSION of one chunk position across re-mines (one logical chunk, N layers). superseded_at — null infrastructure for the future cooldown / archive mechanic; PR B will populate it. - New palace.make_id(prefix, *parts) helper centralises construction of parent_drawer_id, stack_id, and the diary variants — single helper, consistent formula across all four miners. - searcher._expand_with_neighbors now scopes by parent_drawer_id when present, falling back to source_file for legacy drawers (#1580 fix). The total_drawers count also scopes by parent_drawer_id so re-mines don't over-report. - search() rolls up multi-layer hits to one result per stack_id, surfacing the latest layer with a `[N layers]` badge in the CLI output. - diary_ingest.py: split `full_rebuild` (force-only, fires destruction) from `reprocess_all` (force OR content_changed, re-runs entries additively). Removes the hidden #1593 violation where ANY diary edit silently destroyed the prior version. `_diary_drawer_id_entry` signature uses Optional[str] = None for filed_at (idiomatic Python). - cmd_delete / cmd_show catch specific (CollectionNotInitializedError, PalaceNotFoundError) instead of bare Exception — truly unexpected errors propagate with full traceback. Two new CLI verbs implement the sole destruction path: mempalace delete destroys by drawer_id / stack_id / parent_drawer_id with --dry-run + confirmation prompt by default. mempalace show renders a single drawer or a stack of layers with vertical navigation (--layer older / newer / number, or --all-layers). Tests: - 13 new tests in tests/test_additive_mining_preservation.py covering miner, format_miner, diary_ingest preservation (7) + the searcher #1580 scope (1) + the new mempalace delete verb (4, subprocess end-to-end) + the new mempalace show verb (2, subprocess end-to-end with multi-layer stack assertions). - 4 existing tests in tests/test_closets.py updated to match the additive model (assertions inverted from "asserts destruction" to "asserts preservation"). The fourth previously asserted that shrinking a diary file should purge "orphan" drawers — its premise directly contradicted #1593, so it has been replaced with a test that verifies prior entries are preserved as historical layers. - Verification matrix (post-LOCK pass): macOS Python 3.12 (local) : 2279 passed, 4 skipped, 0 failed Linux Python 3.9.25 (orb) : 2272 passed, 11 skipped, 0 failed Linux Python 3.11.15 (orb) : 2273 passed, 10 skipped, 0 failed Linux Python 3.13.13 (orb) : 2273 passed, 10 skipped, 0 failed - Coverage: 84.45% (above 80% threshold). - ruff check + ruff format --check : all clean.

Same ``or ""`` fallback pattern applied. - cli.py:779 (MEDIUM) — cmd_delete's interactive confirmation called input() without guarding against EOFError, which would crash the CLI in non-TTY environments (CI pipelines, piped invocations). The try/except now treats EOF as "no" — destruction is opt-in, so the safe default when we can't ask is to abort. - cli.py:878 (MEDIUM) — out-of-range --layer error message now goes to sys.stderr (was stdout), matching the other error messages in cmd_show. Self-review honest note: LOCK-3 in #1628 changed _diary_drawer_id_entry's filed_at default from "" to Optional[str] = None for idiom, which made None more reachable in metadata.

ChromaDB raised a validation error, the broad `except Exception` swallowed it, and the function fell back to "return just the matched drawer." End result: the #1580 fix appeared to work but the parent_drawer_id scope was never actually applied. Fix per gemini's exact suggestion: when ``parent_drawer_id`` is present, query by ``parent_drawer_id + chunk_index`` only — parent_drawer_id is already implicitly scoped to one source_file by its construction (sha256 of wing + room + source_file + filed_at), so dropping the source_file clause preserves the intended scope while staying within ChromaDB's two-dict limit. When ``parent_drawer_id`` is absent (legacy drawers), the original ``source_file + chunk_index`` filter is used. While exercising the real code path, the existing ``test_neighbors_do_not_cross_parent_drawer_id`` test surfaced a SECOND latent bug: ``neighbors.documents`` used attribute access on the dict that ChromaDB returns from ``get(...)``. That access raised AttributeError on every neighbor expansion — the same broad ``except Exception`` masked it, returning the fallback shape. Both bugs had been silently hiding behind the same swallow. Fixed by switching to ``neighbors["documents"]`` / ``neighbors["metadatas"]`` subscript access (matches the existing test fixture pattern in tests/test_additive_mining_preservation.py). Also added defensive ``(meta or {}).get(...)`` for the chunk_index extraction and a hybrid attribute/subscript shim for ``total_drawers`` ids access. Test update: the previous ``test_neighbors_do_not_cross_parent_drawer_id`` was a false-positive — it used MCP add_drawer with empty source_file, which hits the ``if not src`` early-return guard in ``_expand_with_neighbors`` BEFORE reaching the $and filter. So the test passed regardless of whether the filter scoping logic was correct or broken. The test now seeds ChromaDB directly with two parent_drawer_id groups that deliberately share a non-empty source_file, exercising the exact path Igor's #1580 issue describes. Verified: the test FAILS on the buggy code (before this commit) and PASSES on the fixed code. Two of the four prior amendment fixes received explicit confirmation from gemini's re-review: - cli.py EOFError on input() — "correct and handles the non-interactive environment issue effectively." - cli.py stderr for out-of-range — "correct and consistent with the existing CLI patterns."

Two unrelated chunked drawer groups sharing the same `source_file` could still leak across the enrichment boundary into a single rendered result. @mvalentsev had filed PR #1582 carrying the same fix in a cleaner shape — a shared `_scoped_source_filter` helper applied at both `_expand_with_neighbors` and the enrichment block, with `_parent_drawer_id` threaded through internal search hits and stripped before return. We carry his patch into this amendment verbatim; PR #1582 to be closed after merge. Three corrections / honest acknowledgments 1. @mvalentsev also flagged the amendment-2 commit body's claim that `.documents` attribute access "raised AttributeError in every code path." That was empirically wrong. `_expand_with_neighbors` receives a `ChromaCollection` wrapper from `palace.get_collection()`, whose `get()` returns a `GetResult` dataclass that inherits `_DictCompatMixin` — both `.documents` and `["documents"]` resolve. The crash I observed was in my amendment-2 test against a raw `chromadb.PersistentClient(...)`; I extrapolated to production without tracing `drawers_col` back through the wrapper. /bt miss by me. The subscript change can stay in (the test does guard against the wrapper ever dropping the mixin), but the rationale in the amendment-2 body is wrong. 2. The new amendment-2 test (test_neighbors_do_not_cross_parent_drawer_id in tests/test_additive_mining_preservation.py) was updated to use `palace.get_collection()` (the production path) instead of raw chromadb. Matches the production exercise; passes against the wrapper as it should. 3. mvalentsev's filter uses a 3-clause `$and` in `_expand_with_neighbors` (source_file + chunk_index + parent_drawer_id). Gemini's note on amendment-2 about a "2-only $and limit" turned out to be overcautious — empirically verified by both mvalentsev's test in PR #1582 and our new search_memories test running green against the wrapper. We adopt mvalentsev's 3-clause shape. §1.8 styleguide audit — every bare `where={"source_file": ...}` in mempalace/ Per the new §1.8 styleguide panel (partial-scope-key-migration), a fix that introduces a new scope key must grep every query against the OLD coarser key and either migrate it or document why it is exempt. Full repo audit, six external sites: - searcher.py Two sites already in scope (both call `_scoped_source_filter` via mvalentsev's patch). Strict grep for bare `where={"source_file":` in searcher.py returns empty. VERDICT: clean. - sync.py:305 `closets_col.get(where={"source_file": {"$in": ...}})` — closet bulk purge during sync. Closets don't carry parent_drawer_id (their `upsert` at `palace.py:421` only takes the base metadata dict). `$in` over a list explicitly signals bulk file-global intent. VERDICT: not a candidate. - diary_ingest.py:235 `drawers_col.delete(where={"source_file": source_file})` — inside the `if full_rebuild:` branch. Comment is explicit: must clear ALL drawers for the source (legacy `drawer_diary_` prefix, v2 prior-pass orphans, entry-boundary shifts). File-global is the whole point of full_rebuild. VERDICT: not a candidate. - palace.py:395 `closets_col.delete(where={"source_file": source_file})` — closet purge before re-mine. Same family as sync.py:305 above: closets don't carry parent_drawer_id. VERDICT: not a candidate. - palace.py:763 `collection.get(where={"source_file": source_file}, limit=1)` in `file_already_mined()` (extract_mode-is-None branch). Under PR #1593's additive mining, multiple parent_drawer_id groups for the same source_file can exist (one per mining pass); `limit=1` returns whichever ChromaDB happens to order first, and the function then checks `source_mtime` against that arbitrary group. If a stale group is picked when the latest group's mtime matches, the function returns False and the additive miner writes yet another duplicate layer. VERDICT: real bug, separate scope. Fixing correctly requires either iterating all groups or a fuzzy-mtime query; ChromaDB's `where` doesn't support fuzzy float equality, so the fix is bigger than a one-line patch and exceeds this amendment's scope. Filing follow-up issue. - palace.py:771 Paginated `collection.get(where={"source_file": source_file}, limit=1000)` in `file_already_mined()` (extract_mode-is-set branch). Full paginated scan with Python-side mode filtering downstream. File-global by design. VERDICT: not a candidate. - convo_miner.py:118 Paginated `collection.get(where={"source_file": source_file}, limit=1000)`. Same shape as palace.py:771. Comment confirms file-global intent ("deleting newer general-mode drawers for the same transcript"). VERDICT: not a candidate.

This amendment carries the three remaining ones verbatim. Three new tests (all in tests/test_closets.py, TestDrawerGrepExpansion): - test_expand_backwards_compat_no_parent_drawer_id_returns_all_source_neighbors Pins legacy-drawer behaviour: when a hit has no `parent_drawer_id` in its metadata (drawers written before the field existed), neighbor expansion still returns ALL chunks under the `source_file` scope. Catches a regression where the new scoping helper would accidentally narrow the legacy path. - test_expand_isolates_asymmetric_groups_under_shared_source_file Asymmetric coverage — group A has 1 chunk, group B has 3 chunks, shared source_file. Defensive edge case that catches a regression where the helper would over-count or under-fetch when one group is much smaller than the other. - test_expand_empty_string_parent_drawer_id_treated_as_absent Contract pin — an empty-string `parent_drawer_id` value (`""`, e.g. from a stripped JSON field) degrades to the 2-clause file-global filter, matching the `if parent_id:` truthiness check in `_scoped_source_filter`. Without this pin, a future refactor that switched the check to `if parent_id is not None:` would silently change behaviour for the empty-string case. Cedar's amendment-3 test (`test_search_memories_enrichment_isolates_by_parent_drawer_id`) overlaps with @mvalentsev's `test_hybrid_search_enrichment_isolates_chunks_across_drawers_sharing_source_file` in surface and intent. Both stay — different fixture setups exercise the same code path slightly differently, and the redundancy is the cheap kind. Net new in this amendment: 3 tests. Honest correction on the `$and` limit claim — round 2 The amendment-2 commit body said gemini's "ChromaDB $and only accepts exactly two dictionaries" finding was the reason I rewrote _expand_with_neighbors to drop `source_file` when `parent_id` is present. The amendment-3 body softened this to "overcautious for the wrapper layer" and adopted @mvalentsev's 3-clause shape. @mvalentsev went further and cited the actual ChromaDB source — `validate_where` at chromadb/api/types.py requires `$and`/`$or` to hold AT LEAST two expressions (`len(value) <= 1 -> raise`), with NO upper bound. The codebase already builds a 3-clause $and at `mcp_server.py:1764` (diary list with wing + room + agent), through the same wrapper. So gemini was directionally wrong (it's a minimum, not a maximum), and my 2-clause amendment-2 workaround was unnecessary all along. @mvalentsev's 3-clause shape (which we already carried in amendment-3) is the correct production form. Keeping `source_file` in the neighbor filter does not lean on `parent_drawer_id` always being derived from `source_file`, and costs nothing. The styleguide §1.8 panel referenced gemini's 2-only claim as the amplifier of the partial-scope-key-migration defect class. That reference is now wrong and should be removed or rewritten when someone next touches §1.8. Filing a separate small PR to update the private styleguide; not in scope for this amendment to mempalace.
