Good catch, thanks. sync_markdown_queries called load_queries(pairs, upsert=True), whose delete step keyed only on nl_query, not source, so a markdown pair could clobber a seed or view row with the same nl. Fixed in f075ee7: markdown pairs are now filtered against existing seed/view nl_query values before the upsert, with a regression test that reproduces the collision and fails without the fix. |

Verdict: request changes — 1 blocking.
The bug in #2702 is real and commit b4de068f fixes it correctly. The follow-up commit f075ee77 ("protect seed/view rows from a markdown-sync nl collision") introduces a worse regression than the one it fixes, and the PR's own test encodes the regression as intended behaviour.
🔴 Blocking — the seed-collision pre-filter permanently drops user-authored examples
sync_markdown_queries filters markdown pairs against existing seed/view nl_query values before the upsert. A knowledge/sql/*.md file whose NL matches a generated seed NL (seeds are formulaic: List all {model}, Total {col} in {model}) is then never indexed, and any previously-indexed row for it is deleted as "stale".
Reproduced against this branch (f075ee77), a project with one orders model:
$ wren memory index
Indexed 2 schema items, 1 seed queries.
$ wren memory store --nl "List all orders" --sql "SELECT id FROM orders WHERE status <> 'test'"
Stored: knowledge/sql/list-all-orders.md
$ wren memory index
Indexed 0 pair(s) from knowledge/sql/. Forgot 1 stale pair(s).
The pair a user just confirmed is deleted on the next routine reindex and reported as stale while its markdown file is sitting on disk. Consequences:
wren memory checkenters the same unfixable loop this PR set out to fix, inverted. It reports1 not indexed — run 'wren memory index'on every run, andindexcan never clear it (verified across 3 consecutiveindexruns).- Recall silently serves the wrong SQL under the user's own filename.
_annotate_markdown_pathsmatches on exact NL, so the surviving seed row gets annotated withpath = knowledge/sql/list-all-orders.mdwhile carryingSELECT * FROM orders LIMIT 100— not what that file contains.
Same scenario on main and on this PR's first commit b4de068f: Indexed 1 pair(s) from knowledge/sql/., check → In sync., recall returns the user's SQL. So the regression is entirely the 8-line pre-filter added in f075ee77.
test_sync_preserves_seed_row_whose_nl_collides_with_markdown_pair asserts result["loaded"] == 0 and total == 1 — i.e. it locks in the dropped markdown pair as correct, which is why the rest of the suite stays green.
Suggested fix: drop the pre-filter (revert the store.py hunk of f075ee77). The premise of that commit — that the upsert "silently deleted a protected row" — overstates the harm: seed rows are regenerated from the manifest by index_schema on every index/watch reindex, so a clobbered seed is self-healing, whereas a dropped markdown pair is permanent. Explicit user content should win over an auto-generated seed, which is what main does today. If seed precedence really is wanted, it needs to at minimum (a) not leave check in a permanent unfixable state and (b) tell the user their file was skipped.
🟡 The fix's own premise breaks when a legacy queries.yml is present
In index, sync_markdown_queries runs before the legacy queries.yml loader in the same command. Those pairs are not markdown-backed, so every run deletes and re-embeds them:
--- index run 2 ---
Indexed 1 pair(s) from knowledge/sql/. Forgot 1 stale pair(s).
Loaded 1 pair(s) from queries.yml (legacy) (0 skipped).
--- index run 3 --- # identical, forever
Forgot 1 stale pair(s) is reported on every run for a pair that is not stale and is re-added two lines later, plus an unnecessary embedding round-trip each time. check still reports the drift afterwards, so the claim that index now clears what check reports does not hold here. Consider running the sync after the legacy load, feeding the yml pairs into the sync's current set, or tagging them source:legacy and adding that to _NON_MARKDOWN_SOURCES.
🔵 Minor

Verification performed: pytest tests/unit/test_memory.py → 103 passed; ruff format --check src/ and ruff check src/ clean; behavioural repro of findings 1 and 2 run against main, b4de068f, and f075ee77 (Python 3.11, WREN_EMBEDDING_MODEL=paraphrase-MiniLM-L3-v2).
…index load_queries(pairs, upsert=True) only upserts nl_query values present in the current batch, so a row whose markdown example was deleted or renamed stays in query_history forever and keeps being recalled, even though `wren memory check` tells the user that re-running `wren memory index` fixes it. Add MemoryStore.sync_markdown_queries(pairs), which upserts and then forgets any non-seed/non-view row whose nl_query is absent from the current markdown set, using the same "stale" definition check() already reports. Use it at the three call sites that treat knowledge/sql/*.md as the complete source of truth: cli.py's index and watch commands, and index_backend.py's LanceDBIndex.rebuild. Fixes Canner#2702
sync_markdown_queries called load_queries(pairs, upsert=True), whose upsert path deletes every existing row sharing a pair's nl_query regardless of its source tag. A markdown pair whose nl happened to match an existing seed or view row's nl_query silently deleted that protected row and replaced it with a markdown-sourced one, defeating the seed/view exclusion the rest of the method already applies to its own forgotten-row computation two lines below. Filter markdown pairs against existing seed/view nl_query values before the upsert call, so a colliding pair is skipped instead of clobbering the protected row.
f075ee7's pre-filter excluded a markdown pair from sync_markdown_queries whenever its nl_query matched an existing seed/view row, to keep the upsert from clobbering the protected row. In practice this permanently drops the markdown pair instead: seed nl text is formulaic (e.g. "List all orders"), a colliding user-authored example is skipped forever, its row still gets deleted as stale by the exact filter below it since the markdown pair is no longer indexed, and check/index enter a loop that no reindex clears. Revert the filter: a seed row is regenerated by index_schema() on every reindex, so letting the upsert overwrite it (as it always has) is self-healing, while a dropped markdown pair is not. Renamed and rewrote the regression test the pre-filter added to assert this instead. Separately, tag queries.yml pairs loaded by index() as source:legacy and add "legacy" to store._NON_MARKDOWN_SOURCES, so sync_markdown_queries no longer treats them as stale and re-embeds them on every run. check()'s own stale filter duplicated that set as a hardcoded ("seed", "view") tuple, which would otherwise keep reporting a legacy pair as unindexed drift that index() can never clear; it now imports the same constant. cli._parse_source duplicated store._tag_source verbatim, so it now delegates to it instead of drifting from it a second way. Adds a CLI-level test covering two consecutive index+check cycles on a project with only a legacy queries.yml, and a store-level test for sync_markdown_queries leaving a legacy row alone.

Verdict: request changes — 1 blocking.
The root-cause analysis is right, and the markdown-backed path works — verified end to end (wren memory store → wren memory index keeps the row). The earlier seed pre-filter regression is correctly reverted in b4c1a980. The blocking problem is the scope of the new delete.
🔴 Blocking — sync_markdown_queries deletes rows that were never markdown-backed
sync_markdown_queries forgets every row whose source is not in _NON_MARKDOWN_SOURCES = {seed, view, legacy} and whose nl_query is absent from knowledge/sql/. But source:user is not a synonym for "came from markdown" — it is just the default source for any pair that doesn't say otherwise. Two live paths produce source:user rows with no markdown file, and both now lose data on the next wren memory index.
1. wren memory load <file>.yml — a documented, non-deprecated command that writes no markdown and defaults source to "user" (sources = Counter(p.get("source", "user") ...) → load_queries → tags = "source:user").
# this branch
$ wren memory load pairs.yml
Loaded 1 pair(s) (1 new).
$ wren memory index
Indexed 0 pair(s) from knowledge/sql/. Forgot 1 stale pair(s).
$ wren memory list
No pairs found.
# identical steps on main (8d23753e)
$ wren memory index
Indexed 0 schema items.
$ wren memory list
Revenue by region | SELECT region, SUM(amount) FROM o GROUP BY region | source:user
Showing 1-1 of 1 pairs.
The YAML file may live anywhere, or have been deleted after the import — there is nothing for a later index to restore from.
2. Existing users whose queries.yml has already been consumed. The new source: legacy tag only helps while queries.yml is still on disk. A user who imported it on an older version (rows land as source:user) and then removed the file loses those rows on their first index after upgrading:
# index on main with queries.yml present → row stored as source:user
# user removes queries.yml, upgrades, runs index on this branch:
Indexed 0 pair(s) from knowledge/sql/. Forgot 1 stale pair(s).
$ wren memory list
No pairs found.
The in-place upgrade path where queries.yml is still present does self-heal (forget → reload as source:legacy; second run clean, check reports "In sync.") — I verified that separately. It is only the consumed-and-removed case that is unrecoverable, and that is the expected end state for a file the code itself describes as transitional.
Worth naming explicitly: check() previously only reported these as drift. Turning that report into an unconditional delete is the actual change in blast radius, and neither the PR description nor the CLI output warns that anything is being destroyed permanently.
Suggested directions, in order of preference:
- Track provenance instead of inferring it. Tag rows written by the markdown sync distinctly (e.g.
source:markdown, or record the originatingpath—load_query_pairsalready returns it) and forget only rows carrying that provenance. "Don't delete what you didn't write" removes the whole class of bug rather than enumerating exemptions. - Minimal stopgap (still leaves a hole for an explicit
source: userinside a loaded YAML): defaultwren memory loadto a non-markdown source and add it to_NON_MARKDOWN_SOURCES. - Either way, consider making the destructive step opt-in for one release (
index --prune, or list what would be dropped and require a flag), since existing indexes containsource:userrows of unknowable provenance.
Verification behind the above: real CLI runs on this branch and on main with WREN_MEMORY_BACKEND=lancedb and WREN_EMBEDDING_MODEL=paraphrase-MiniLM-L3-v2; pytest tests/unit/test_memory.py → 105 passed on this branch.
…m source
sync_markdown_queries's forget step scoped its stale scan to any row whose
source wasn't in {seed, view, legacy}, which is not the same set as "rows
this sync wrote". source:user is also what wren memory load gives a pair
with no source of its own, and what a pre-source:legacy queries.yml import
already carried, so both lost their data permanently on the next
wren memory index even though neither was ever markdown-backed.
Tag every row the sync's own upsert writes with an explicit
_MARKDOWN_SYNC_TAG token (kept separate from the source: tag) and scope the
forget scan to that tag instead of the source exclusion list, so the sync
only ever deletes a row it wrote itself. list_queries, count_queries_by_source,
dump_queries and forget_queries_by_source filtered on an exact match against
the whole tags string, which the extra token would have broken for every
markdown-synced row; switched them to parse the source token instead.
Adds coverage for a view row surviving the same way seed/legacy already did,
for the wren memory load scenario, for a pre-upgrade queries.yml import with
the file already gone, and for --source filtering across the new tag.

You're right. source:user isn't evidence of markdown backing, it's also what wren memory load defaults to and what a pre-source:legacy queries.yml import already carried. Went with your first option. sync_markdown_queries's own upsert now tags every row it writes with an explicit provenance marker separate from the source: tag, and the forget scan is scoped to that marker instead of the seed/view/legacy exclusion list, so it only ever deletes a row it wrote itself. wren memory load rows and pre-upgrade legacy imports never carry it. That marker broke list_queries/count_queries_by_source/dump_queries/forget_queries_by_source, which matched tags by exact string equality against "source:X" and would have gone blind to every markdown-synced row with --source user. Fixed all four to parse the source token instead. Skipped the opt-in-for-a-release suggestion: the provenance fix already narrows the delete to what this method wrote, which was the actual bug, so I left that bigger change for you to weigh in on. Tested: reproduced your wren memory load repro on unpatched code (same "Forgot 1 stale pair(s)" then "No pairs found"), confirmed it survives on the fix. Full tests/unit/test_memory.py: 110 passed, including the seed-collision test unchanged. Added coverage for a view row, the load scenario, a pre-upgrade queries.yml row with the file gone, and --source filtering against a tagged row. ruff clean, CI green. Not checked: wren memory check still infers "not markdown-backed" the old way, so it can call a load row stale even though index is now a no-op for it. Left that for a follow-up. Also haven't tried this outside Linux. |

Reviewed against origin/main (4d167fc) vs head 79980f1, with the memory extras installed and the CLI exercised end to end. The root cause is correctly identified and sync_markdown_queries is the right home for the fix — the headline behaviour works (Indexed 1 pair(s) from knowledge/sql/. Forgot 1 stale pair(s)., and the deleted pair stops surfacing in recall).
Two blocking issues, both from one structural gap: the write path records markdown provenance via _MARKDOWN_SYNC_TAG, while check() still infers it from the source: name. One is a user-visible regression on the documented wren memory export migration path; the other silently widens what wren memory forget --source user deletes. Details and suggested changes are inline — five of them compose into one coherent end state, so please apply them together.
Two regression tests are still missing; these both fail on this branch as it stands and pass with the inline changes applied:

(For what it's worth I don't reproduce the 3 test_served_content_guard.py failures the description mentions — they pass here.)
Two smaller notes, no action needed. forget_queries_by_source swapped an atomic table.delete(where) for a full-table read-modify-overwrite; that's defensible now that it shares the forget_queries_by_ids mechanism, but it loses atomicity and load_queries(overwrite=True) now does one full rewrite per distinct source — worth a line saying why that's acceptable. And LanceDBIndex.rebuild() has no production caller (tests only), so "three call sites" in the description is really two plus an interface method.
…c's own provenance tag check() and the write path defined "markdown-backed" two different ways. check() inferred it from source (excluding seed/view/legacy), while sync_markdown_queries records it explicitly via _MARKDOWN_SYNC_TAG. A source:legacy pair exported by `wren memory export` lands in knowledge/sql/ as source: legacy, which check() then excludes from its own indexed set, so it reads as permanently "not indexed" and no repeated `index` run can clear it. Switch check() to read the same provenance tag the sync itself writes. Separately, the --source filters (list/count/dump/forget) moved to _tag_source(tags) == source, which defaulted an untagged row to "user". A wren memory store / MCP store_query pair carries the caller's own free-form tags (or none), so a bare --source user, including forget, swept those rows up too. _tag_source now returns None for a row with no source: token, and a new cli._parse_source keeps the "user" display default for list/export output; it is not the same predicate as the delete-scoping one. Also drops _NON_MARKDOWN_SOURCES, whose only consumer was removed by the check() change, and corrects two comments left describing the old source-exclusion reasoning. Adds regression coverage for both: an export-then-index-then-check round trip, and --source filtering across store/load/sync-tagged rows mixed with untagged ones.

Appreciate you catching the seed-collision regression and then the source:user gap, tracking provenance directly instead of inferring it is a much cleaner fix than what I had. |

Root cause
MemoryStore.load_queries(pairs, upsert=True)upserts every pair in the batch bynl_query, but never removes a row whosenl_queryis no longer in the batch. Thethree call sites that treat
knowledge/sql/*.mdas the complete source of truth forquery_history(cli.py'sindexandwatchcommands, andindex_backend.py'sLanceDBIndex.rebuild) all pass the current markdown pairs straight through thisupsert-only call, so a deleted or renamed example is never forgotten and keeps
surfacing in semantic recall.
check()already computes exactly this drift (stale = indexed_user - md_nls) and tells the user to fix it by runningindex, butindexdoes not actually clear it.
Fix
Add
MemoryStore.sync_markdown_queries(pairs): upserts as before, then lists thecurrent rows and forgets any whose source is not
seed/viewand whosenl_queryisabsent from
pairs, mirroringcheck()'s own "stale" definition on the write pathinstead of only the read-only report. The three call sites above now use it.
Verification
tests/unit/test_memory.py(TestMarkdownSourcedIndex):deleting a markdown example and re-syncing forgets the row and it no longer recalls;
seed/view rows survive a sync even though they have no markdown file; deleting every
markdown example forgets every markdown-sourced row;
