Answers the independent review in SECURITY_ANALYSIS.md: both critical findings,
all twelve high, all eighteen medium, and the lower-severity plan drift. The
headline defects were a write path whose lifecycle and version checks sat
outside the serialized operation, an unterminated frontmatter block that was
"repaired" into a new note, delayed embeddings landing on reused chunk ids, and
a startup that could not bind its listeners while the embedding backend was
unreachable.

Also in here, found while deploying rather than by the review:

- Referrer-Policy: no-referrer made browsers send `Origin: null` on form
  submissions, so the CSRF guard refused every write in the UI. It had never
  worked in a browser on any build; the tests missed it by setting Origin by
  hand.
- Renaming a note orphaned its inbound links at the next reindex of each source,
  silently and long after the rename.
- An idempotency claim abandoned by a cancelled request wedged its request_id
  for the full 24h TTL.

The UI is translated to English and rebuilt around design tokens, and the test
suite grows from 227 to 406, including the deterministic concurrency and barrier
tests the review asked for.

`{reason, source, created, resolved}` here and the indexer rewrites the `flags` table from it on

# Security, Correctness, and Plan-Drift Analysis
Date: 2026-09-12
Reviewed revision: `4cb9639` (`master`)
Reference contract: `PLAN.md`
Scope: `src/mdmem`, `tests`, `eval`, `deploy`, `Containerfile`, `README.md`
## Executive summary
The current test suite is green (`227 passed`) and `ruff check src tests` passes, but important
concurrency, data-integrity, authentication, and recovery behavior remains untested. This review
found:
- 2 critical findings
- 12 high-severity findings
- 18 medium-severity findings
- several lower-severity plan and coverage gaps
The two most urgent defects are:
1. lifecycle/version decisions are made before the service write lock is acquired, allowing
concurrent requests to resurrect rejected notes, overwrite accepted edits, or recreate a
deleted note; and
2. an unterminated frontmatter block is still classified as a new hand-written note and
destructively rewritten.
The next tier is dominated by stale embedding races, filename/frontmatter identity split-brain,
idempotency races, secret leakage through secondary write channels, and startup behavior that can
prevent the documented lexical-only degradation mode.
Severity here measures likely impact to confidentiality, integrity, availability, or the core
human-promotion trust boundary. It is not a CVSS score. No fixes were made as part of this review.
## Method
The review combined independent passes over storage/retrieval, service/MCP, and UI/deployment/eval,
then rechecked findings against the current working tree and `PLAN.md`. High-impact claims were
confirmed with controlled temporary-vault reproductions. No production vault or configured live
index was used.
Representative observed results included:
- reject/update race: `reject -> archive`, then stale update -> `inbox`; final body was the agent's
text and `rejected` was gone;
- two concurrent identical `memory_write` calls with one `request_id` created two distinct notes;
- delayed old embedding and new embedding both used chunk ID `1`; the old vector was stored against
the new chunk and `vec_pending` became `0`;
- deleting a closing `---` renamed and rewrote an active fact, changed its type to `note`, emptied
its tags, and moved the former frontmatter into the body without reporting an error;
- a valid allowed `Origin` paired with `Host: evil.example` was accepted;
- signed ID tokens with `exp: NaN`, `exp: Infinity`, multiple audiences plus a mismatched `azp`, and
a missing `sub` were accepted;
- a note written during the scan-to-watcher startup gap remained on disk but absent from the index;
- `MCP_TOKEN=...`, `AWS_SECRET_ACCESS_KEY=...`, `github_pat_...`, `glpat-...`, `npm_...`, and `hf_...`
examples all evaded the secret scanner.
## Critical findings
### C-01 — Lifecycle and optimistic-version checks are outside the serialized operation
Affected code: `src/mdmem/service.py:465-545`, `572-605`, `613-619`, `655-719`
Plan: §2.4, §6 single-writer rule, §9 optimistic versioning, §14.10
`update_note`, `approve`, `reject`, `edit`, and `hard_delete` read the note and make lifecycle or
version decisions before acquiring `_write_lock`. Only the eventual `_persist` or deletion block
is serialized. A queued operation therefore acts on a stale `Note` object after an earlier queued
operation has changed the canonical file.
Confirmed consequences:
- Two concurrent inbox updates with the same `expected_version` both succeed; one silently
overwrites the other and one returned version is stale immediately.
- A rejected note can be rewritten back into `inbox`, losing `rejected: true`.
- An update queued behind `hard_delete` can recreate the deleted ULID and file after deletion
reported success.
- An agent update queued behind approval can move an owner-approved note back to inbox with the
agent's text.
Required regression coverage: deterministic barrier tests for update/update, reject/update,
approve/update, archive/update, edit/update, and delete/update. The read, validation, mutation,
file write, and synchronous index update must be one serialized operation.
### C-02 — Missing closing frontmatter delimiter causes destructive “repair”
Affected code: `src/mdmem/notes.py:67-95`, `src/mdmem/index.py:264-305`
Plan: §4 identity/frontmatter preservation, §6.3 safe parsing, §14.25/§14.26
Strict parsing only raises for malformed YAML after the frontmatter regex has matched both
delimiters. If the closing `---` is missing, both lenient and strict parsing return an empty map.
`read_and_fix` then treats an existing canonical note as a clean hand-written note.
In the reproduction, an indexed active `fact` was renamed and rewritten, its real title was
replaced by the old filename stem, tags were erased, and the former YAML became body text. The
degraded metadata also replaced the good index row. Clearing `superseded_by` this way can make an
obsolete fact searchable again. The history snapshot made during repair contains the already
broken text and is not a dependable last-good recovery point.
Required regression coverage: remove only the closing delimiter, then exercise both full scan and
watcher sync. The file, path, identity, and last-good index row must remain unchanged while a clear
error is reported.
## High-severity findings
### H-01 — Delayed embeddings can be attached to newer text
Affected code: `src/mdmem/index.py:24-29,61-127,360-367`,
`src/mdmem/service.py:227-242,714-719`
Plan: §6 single-writer consistency, §7 recovery, §14.7
`PendingEmbed` records `key_hash`, but `_embed_items` discards it and `store_vectors` stores solely
by numeric chunk ID. Embedding happens after `_write_lock` is released. Reindexing deletes and
reinserts chunks, and SQLite can immediately reuse the old integer ID.
A delayed response for hash A can therefore overwrite the vector for current hash B and mark B as
complete. This affects ordinary writes, background retries, and `reembed_all`. If the old ID is not
reused, the code may instead attempt to create an orphan vec row.
Required regression: hold an old embed request open, complete an edit/reindex, then release it.
Store a vector only when both chunk ID and `embed_text_hash` still match in the same transaction.
### H-02 — Filename/frontmatter disagreement creates identity and lifecycle split-brain
Affected code: `src/mdmem/vaultio.py:55-69`, `src/mdmem/index.py:210-305`,
`src/mdmem/db.py:25-32`
Plan: §4 identity and folder lifecycle source of truth
`read_and_fix` trusts any syntactically valid frontmatter ULID without checking the ULID encoded in
the filename. Confirmed failure modes:
- Editing a canonical file's frontmatter ID to another ULID makes indexing fail on the unique path
constraint while preserving a stale row under the filename ID. The file's new ID cannot be found
by `Vault.find`.
- An active original plus an archive copy carrying the original frontmatter ID is accepted with no
conflict; last-file-wins indexing can hide the active original as archived while `Vault.find`
still reads the active file.
- A file such as `active/manual.md` with a valid frontmatter ID is indexed, but `Vault.find(id)` and
`memory_get` cannot locate it because lookup uses the filename ID.
Required regression: reject mismatched IDs and duplicate lifecycle copies without changing the
last-good row. Also test valid-frontmatter-ID files with noncanonical names.
### H-03 — Normal vault deletion leaves inbound links invisibly dangling
Affected code: `src/mdmem/index.py:153-158`, `src/mdmem/service.py:180-190`
Plan: §5 unresolved links, §6 vanished-file handling, §10 health report
The UI hard-delete path now reindexes inbound sources, but `Indexer.remove`—used by ordinary
filesystem deletion through scan/watcher—deletes only outgoing links. Inbound rows retain the
deleted ULID rather than reverting to `unresolved:<target>`, so the unresolved health count remains
zero and the broken reference is invisible until its source is reindexed for another reason.
Required regression: delete a target through both scan and watcher paths; surviving source links
must become unresolved and flags for the vanished note must be handled explicitly.
### H-04 — Service updates can write NFC to disk while indexing NFD
Affected code: `src/mdmem/notes.py:98-130`, `src/mdmem/vaultio.py:88-119`,
`src/mdmem/service.py:531-545,655-684,714-719`
Plan: §4 and §14.8 NFC normalization
`dumps` normalizes a deep copy, not the live `Note`. `_persist` writes the normalized serialization
and then indexes the original object. An inbox update with NFD text produced NFC on disk but NFD in
`chunks.body` and in the embedding input. Because the indexed file hash is the canonical disk hash,
the watcher considers the service event already handled and does not repair the mismatch.
Required regression: update and UI-edit with NFD in body, frontmatter, relations, and link targets;
assert the live note, disk, chunks, FTS/trigram text, links, and embedding input all use NFC.
### H-05 — Scan-to-watcher startup gap can permanently miss changes
Affected code: `src/mdmem/service.py:117-157`
Plan: §6 startup scan/watcher, P1 live-edit latency
The watcher starts only after scan, secret scan, self-test, and pending embeddings. A file changed
after its scan pass but before watcher registration emits no event. A controlled reproduction wrote
a second valid note while `embed_pending` was blocked; after startup finished, the file existed but
the note was not indexed.
Required regression: mutate a file after initial scan while startup embedding is paused. Start
watching before reconciliation or run a final scan after watcher registration.
### H-06 — A Bifrost outage can put Kubernetes into a cold-start restart loop
Affected code: `src/mdmem/server.py:67-72`, `src/mdmem/service.py:117-157`,
`src/mdmem/embed.py:160-199`, `deploy/kubernetes/apps/apps/mdmem/mdmem/app/deployment.yaml:58-69`
Plan: §7, §13a.3, §14.17 lexical-only degradation
The process awaits `svc.start()` before either listener binds. Startup synchronously awaits an
embedding self-test and pending embeddings. Each can spend three 60-second attempts. The deployment
has liveness starting after 30 seconds, no `startupProbe`, and the default failure threshold.
Kubernetes can kill the pod before `/healthz` ever binds, repeatedly preventing the promised
lexical-only mode.
Required regression: start the real server with a blocking/blackholed embedder and prove liveness,
readiness, and lexical search bind before the probe deadline. Deployment tests must cover the
startup probe budget.
### H-07 — Common explicit credential forms evade the secret scanner
Affected code: `src/mdmem/secrets.py:11-29`
Plan: §9 and §14.12
The generic assignment regex requires a word boundary before names such as `token` and `secret`.
Because underscore is a word character, common environment variable names evade it. Provider
patterns are also incomplete. Confirmed misses include `MCP_TOKEN=...`,
`AWS_SECRET_ACCESS_KEY=...`, `OPENAI_API_KEY=...`, `GITHUB_TOKEN=...`, `github_pat_...`, `glpat-...`,
`npm_...`, and `hf_...`.
Required regression: current provider token formats and standard environment assignments,
including `export`, quoting, mixed case where applicable, and every serialized note field.
### H-08 — Secondary persistent channels bypass secret rejection and can leak into audit
Affected code: `src/mdmem/service.py:556-569`, `src/mdmem/mcp_server.py:90-128,350-354`
Plan: §4 untrusted `source`, §9 audit, §14.12
`flag.reason` is agent-controlled and persisted in SQLite without a scan. `request_id` is stored and
logged raw without a size or secret check. Audit `source` is copied from self-reported note metadata
before note validation. A write rejected for `source.harness=AKIAIOSFODNN7EXAMPLE` still copied that
full key into `audit.jsonl`; the same value in a flag reason was stored and returned by `memory_get`.
This is also provenance confusion: the audit UI presents an untrusted, caller-asserted source as
attribution.
Required regression: inspect the audit file after rejected source/request ID values, and test flag
reason storage. Store bounded/redacted identifiers, not unchecked caller strings.
### H-09 — Idempotency is race-prone and has inconsistent key semantics
Affected code: `src/mdmem/mcp_server.py:83-129`, `src/mdmem/db.py:58-59`,
`src/mdmem/service.py:777-813`
Plan: §9 replay guarantee
The guard performs `get -> side effect -> put` without synchronization. Two concurrent identical
writes with one request ID both missed and created different notes. Concurrent different arguments
also both succeeded instead of returning `IDEMPOTENCY_CONFLICT`.
The table primary key is `request_id`, while lookup treats `(request_id, tool)` as the key.
`INSERT OR REPLACE` for a second tool deletes the first tool's replay record. Replaying the original
operation can then repeat its side effect.
Required regression: concurrent same/different arguments, same ID across tools, in-progress
requests, and failure after mutation but before idempotency persistence. Claim and commit an
idempotency key atomically before performing a mutating operation.
### H-10 — Revision approval has no target-version or target-lifecycle check
Affected code: `src/mdmem/service.py:494-528,572-605`
Plan: §2.4 and §9 revision review
A proposal records only `revises`, not the version it was based on. `_merge_revision` blindly loads
the current target and overwrites it. Confirmed outcomes:
- active v1 -> agent proposal v2 -> owner edit v3 -> approve proposal results in v2, silently losing
the newer owner edit;
- active target -> proposal -> reject/archive target -> approve proposal rewrites the archived
target while retaining rejection state, so a later restore promotes the agent text.
Required regression: target edited, archived, rejected, deleted, or superseded after proposal
creation. Approval should refuse stale proposals or require an explicit owner conflict resolution.
### H-11 — Supersede proposals bypass lifecycle and exclusivity invariants
Affected code: `src/mdmem/service.py:548-554,572-593`
Plan: §2.4, §2.6, §9
`supersede` accepts archived, rejected, inbox, and already-superseded targets. A rejected item can be
re-proposed through this path despite the explicit archived-note guard on update. Two successor
proposals can also both be approved: both remain active and point back to the old fact, while the
old note's singular `superseded_by` points only to the second. Search can expose contradictory
“current” facts.
Required regression: archived/rejected/inbox/already-superseded/nonexistent targets, concurrent and
sequential competing successors, and bidirectional chain consistency.
### H-12 — Zero and non-finite embeddings are accepted as healthy
Affected code: `src/mdmem/embed.py:39-42,178-188`, `src/mdmem/search.py:72-74`
Plan: §2.1 known all-zero failure, §7 startup self-test, §14.1
Normalization leaves zero vectors at zero and propagates NaN/Infinity. Shape checks accept them,
including during startup self-test. Two zero vectors have distance zero, which search converts to
cosine `1.0`, creating a falsely perfect semantic match.
Required regression: zero, NaN, and infinite vectors for self-test, documents, and queries. Invalid
vectors must not be cached or stored, and search must degrade to lexical.
## Medium-severity findings
### M-01 — Flags violate the Markdown source-of-truth and recovery contract
Affected code: `src/mdmem/db.py:53-56`, `src/mdmem/service.py:556-569`
Plan: §0 Markdown canonical; SQLite rebuildable
Flags exist only in SQLite. Deleting/rebuilding `index.db` from an unchanged vault changes
`flags_for(id)` from populated to empty. Either make flags canonical in Markdown or explicitly
change the backup/recovery contract and back up this mutable database state.
Missing test: flags survive full index recreation.
### M-02 — Temporal values are unvalidated strings compared lexicographically
Affected code: `src/mdmem/service.py:417-450`, `src/mdmem/search.py:194-199,327-332`
Plan: §2.6, §4 UTC timestamps, §8 filters
Malformed values, offsets, and `valid_from >= valid_until` are accepted. Lexical comparison is not
instant comparison: for example, equivalent offset and `Z` timestamps can filter differently.
Missing tests: RFC3339 validity, UTC normalization, ordering, equivalent instants, and boundary
semantics for stored values and search arguments.
### M-03 — Unicode and trigram lexical hits are not merged by better rank
Affected code: `src/mdmem/search.py:120-150`
Plan: §8.1
The implementation mixes raw BM25 magnitudes from different FTS tables and ignores trigram whenever
the same chunk has a unicode61 hit. This does not implement “keep the better rank per chunk.”
Missing test: controlled rank lists where a chunk is rank 50 in unicode61 and rank 1 in trigram.
### M-04 — Late link resolution misses equivalent slug spellings
Affected code: `src/mdmem/index.py:182-207`
Plan: §5 exact-title then slug resolution
Initial resolution slugifies a target, but late resolution updates only two literal unresolved
keys. `[[Later Note]]` remains unresolved when a later note titled `Later Note` arrives, although
both slugify identically.
Missing tests: whitespace, punctuation, capitalization, and umlaut variants on forward links.
### M-05 — Search accepts invalid bounds and can exceed `max_chars`
Affected code: `src/mdmem/search.py:303-318`
Plan: §8.7, §14.11
The first result is always emitted even when it exceeds the requested budget; zero or negative
budgets still return one result. A negative internal `k` uses Python slicing and can return nearly
all candidates. The current test explicitly permits an 800-character overrun, contradicting the
plan.
Missing tests: `k <= 0`, `max_chars <= 0`, oversized first title/snippet, exact-budget boundary, and
structured MCP validation.
### M-06 — One long token bypasses the chunk target
Affected code: `src/mdmem/chunker.py:50-89`
Plan: §6.4
`_split_words` does not split a single token longer than the limit. Agent content can reach 8,000
characters and hand-authored notes are unbounded, producing oversized chunks.
Missing test: a no-whitespace token larger than the chunk limit, with bounded lossless output.
### M-07 — `is_ulid` accepts overflow encodings rejected by the ULID library
Affected code: `src/mdmem/ids.py:13,38-39`
Plan: §4/§6 valid identity
Validation checks only length and alphabet. Values such as
`ZZZZZZZZZZZZZZZZZZZZZZZZZZ` pass but `ULID.from_str` rejects them as overflow.
Missing property: `is_ulid(value)` implies successful parsing by the canonical ULID implementation.
### M-08 — OIDC claim validation accepts non-finite expiry, missing subject, and bad `azp`
Affected code: `src/mdmem/ui/auth.py:210-245`
Plan: §10 fail closed
Signed tokens with `exp: NaN` and `exp: Infinity` pass because any int/float is accepted and
non-finite comparisons do not expire them. `sub` is not required, allowing an empty-subject session.
When `aud` contains multiple values, `azp` is not required or checked; a token with mdmem among its
audiences but `azp` naming another client was accepted.
Missing tests: finite expiry, required nonempty subject, and multi-audience authorized-party rules.
### M-09 — Scalar group claim is accepted contrary to the fail-closed plan
Affected code: `src/mdmem/ui/auth.py:60-90`, `tests/test_ui_auth.py:59-60`
Plan: §10, P4, §14.21
The code converts a scalar string group to a list, and a test deliberately blesses it. The plan
requires a present-but-wrong-type group claim to return 403.
Required change to coverage: only `list[str]` should pass; scalar, null, mapping, and mixed lists
must fail.
### M-10 — UI POST protection still does not validate Host
Affected code: `src/mdmem/ui/app.py:85-105,464-480`
Plan: §10 Origin/Host allowlist
The recent Origin/Referer fix correctly rejects headerless writes, but when configured origins are
present, Host is ignored. A request with allowed `Origin` and `Host: evil.example` was accepted.
Missing tests: invalid Host with valid Origin, proxy-forwarded host behavior, and the exact deployed
host allowlist.
### M-11 — JWKS is cached forever, breaking key rotation until restart
Affected code: `src/mdmem/ui/auth.py:149-165`
Plan: §10 operationally reliable OIDC
An unknown `kid` does not trigger one forced JWKS refresh. New logins fail after PocketID signing-key
rotation until the pod restarts.
Missing test: cache key A, publish key B, present a B-signed token, and verify one refresh succeeds.
### M-12 — Audit hashes omit actual arguments and unexpected errors vanish
Affected code: `src/mdmem/mcp_server.py:83-129,167,335-339`
Plan: §9 every tool call logged with argument hash, source, latency, IDs
Search hashes only query and `k`, omitting filters. Flag hashes only ID, omitting reason. Different
calls therefore receive identical audit fingerprints. `_guard` catches only `MdmemError`; an
injected database/programming exception produced no audit entry at all.
Missing tests: vary every argument and require a hash change; inject unexpected exceptions and
require `ok:false`, latency, request ID, and a bounded error class.
### M-13 — `memory_flag` is non-idempotent
Affected code: `src/mdmem/mcp_server.py:328-339`
Plan: §9 idempotency
The mutating flag tool has no `request_id`. A transport retry creates duplicate review items. Search
and get also omit the plan's broadly stated optional request ID, though they have no side effect.
Missing test: replaying one flag request creates exactly one flag.
### M-14 — Evaluation can recommend a variant with a catastrophic category regression
Affected code: `src/mdmem/evalharness.py:340-372`
Plan: §11 “without a regression in any category beyond noise”
`pick_default` checks only overall nDCG and confidence intervals. It never examines `per_category`.
Missing test: a candidate with a clear overall win but severe temporal or update regression must
remain unselected.
### M-15 — Eval output is not standards-compliant JSON
Affected code: `src/mdmem/evalharness.py:90-117,160-174,395-425`,
`eval/results/2026-09-12-synthetic-smoke.json:538-541`
Plan: §11 committed JSON result artifact
Unavailable metrics remain `float("nan")`; `json.dumps` emits raw `NaN`, which RFC 8259 does not
permit. The test named as a CLI writer test manually writes a different object and never calls
`run_eval_cli`, leaving serialization false-green.
Missing test: invoke the actual CLI and parse with a strict JSON parser; unavailable values should
serialize as `null`.
### M-16 — Eval latency is order-biased by a shared embedding cache
Affected code: `src/mdmem/evalharness.py:293-312`, `src/mdmem/service.py:99-115`
Plan: §11 fair ablation comparison
Each variant gets an isolated index but retains the configured `cache_db`. The first real-model
variant pays query embedding latency while later variants reuse cached query embeddings, making p95
latency incomparable.
Missing test: instrument backend query calls and prove equivalent cache state or perform an explicit
warm-up excluded from every variant's timing.
### M-17 — Required Prometheus signals are absent
Affected code: `src/mdmem/ui/app.py:75-145`
Plan: §13a.7
Embedding error count, search-latency histogram, and MCP calls by tool/outcome are not exported.
Search/write totals are Gauges rather than Counters. Existing tests only check that generic metrics
exist and omit note content.
Missing test: scrape and assert all required metric families and bounded label cardinality.
### M-18 — UI state filtering and state transitions do not enforce the displayed workflow
Affected code: `src/mdmem/ui/app.py:261-300`, `src/mdmem/service.py:638-653`
Plan: §2.4, §10 Search filters and review workflow
Search `state=inbox` includes both active and inbox notes, while `state=archive` includes active,
inbox, and archive. In addition, the generic state endpoint can promote an inbox revision or
supersede proposal directly to active, bypassing `approve` merge/chain behavior if called manually.
Missing tests: exact results for every state filter and forbidden lifecycle transitions that must
go through approval.
## Lower-severity plan drift and test-suite gaps
- Health has no “run eval” action required by §10 (`src/mdmem/ui/templates/health.html`,
`src/mdmem/ui/app.py:443-460`).
- History compares one snapshot only to current, not any two revisions as required by §10
(`src/mdmem/ui/app.py:313-324`).
- Browse does not offer sorting by tags as required by §10.
- Health audit rows do not display the recorded `source` field.
- “Edit & approve” converts an intentionally empty body to `None`, approving the old body instead
(`src/mdmem/ui/app.py:235-239`). Empty must be saved or explicitly rejected, not ignored.
- `AuditLog.recent` reads persisted history only while its in-memory list is completely empty. After
restart and one new call, Health shows only that call rather than the last 100 across restart
(`src/mdmem/logging.py:77-92`).
- `memory_supersede` omits relations, validity bounds, and source metadata available to
`memory_write`; either complete the §9 schema or narrow the contract.
- Bearer configuration accepts whitespace/non-ASCII values that clients cannot reliably present;
startup should validate a trimmed ASCII token with an explicit minimum length.
- `validate_id` is dead code. ID arguments have no schema pattern or maximum length and are echoed
in `NOT_FOUND` responses.
- The session test named “round trip and expiry” never advances time or tests expiration.
- No route-level OIDC test covers discovery, state, PKCE, nonce carriage, callback errors, cookie
flags, expiry, logout, or signing-key rotation.
- The OIDC HTTP client created in `build_ui_app` has no application shutdown hook calling
`OidcClient.aclose`.
- CLI tests cover help/version but not serve, doctor, reindex, eval, contradictory mode flags,
startup failures, or graceful shutdown.
- The note round-trip property test generates a body but does not assert its round trip and does not
property-test arbitrary unknown-key order/comments.
- The clean manifest template is not directly buildable: `app/kustomization.yaml` references the
intentionally absent encrypted `secret.yaml`; image digest and PocketID client ID remain release
placeholders. These are documented setup blockers, but there is no CI smoke test for the rendered
deployment overlay.
- The only committed evaluation is a synthetic fake-embedding smoke run. It proves harness wiring,
not the P5 acceptance criterion of 50–100 real labelled queries and a production-model tuning
report.
## Test integrity assessment
The suite is useful for sequential happy paths but systematically underrepresents interleavings,
recovery from canonical Markdown, deployment startup, and strict external-format validation.
Highest-value missing test groups, in order:
1. deterministic service concurrency tests around the whole read/check/write operation;
2. chunk-hash-guarded embedding races, including background retry and re-embed;
3. malformed frontmatter delimiter and filename/frontmatter identity conflict cases;
4. startup with a blocked embedding backend plus a mutation during watcher registration;
5. concurrent idempotency and crash-between-side-effect-and-record cases;
6. secret scanning and audit redaction across every persistent channel;
7. full OIDC route tests with strict claims and signing-key rotation;
8. actual CLI eval serialization through a strict JSON parser;
9. disaster rebuild proving all canonical state survives; and
10. deployment render/probe smoke tests.
Some current tests actively encode plan drift rather than merely omitting it:
- `tests/test_ui_auth.py` accepts a scalar group claim despite §14.21;
- `tests/test_search.py` permits the first result to exceed `max_chars` by up to one snippet;
- `tests/test_evalharness.py::test_cli_reports_and_writes_a_json_file` does not invoke the CLI it
names.
## Recommended remediation order
1. Serialize lifecycle/version operations end-to-end and add deterministic race tests.
2. Reject unterminated/mismatched frontmatter without touching the file or last-good index.
3. Guard vector writes by chunk ID plus embedding-text hash.
4. Make startup bind in lexical mode independently of Bifrost and close the scan/watch gap.
5. Make idempotency atomic and reconcile its database key.
6. Close all secret-bearing secondary channels and redact audit fields.
7. Enforce revision/supersede target version, lifecycle, and exclusivity.
8. Validate embeddings, timestamps, ULIDs, OIDC claims, Host, and response bounds.
9. Restore the Markdown-only recovery guarantee for flags or explicitly redesign it.
10. Repair eval selection/serialization/fairness, observability, and the lower-priority UI drift.
## Baseline notes
The following earlier findings are fixed in the reviewed revision and are intentionally not listed
as open defects above: full-field note secret scanning, mandatory `expected_version`, archived-note
update rejection in the sequential case, approval validation, audit-file wiring, ordinary
hard-delete link repair, background retry of pending vectors, safe re-embed on a simple outage,
trigram backfill after toggling it off/on, missing-Origin CSRF rejection, nonce/`exp`/`iat` presence
checks, eval index isolation, reciprocal synthetic supersede data, connection/cache shutdown, and
the direct fusion formula tests.

`rrf`, `rrf-inbox-1.0` and `rrf-bm25-flat` report the *same* nDCG@10 in that run.
That is expected here and is not the shared-state corruption an earlier report had:
none of the 12 seeded notes sit in `inbox/`, so the inbox weight has nothing to
act on, and the two lexical subchannels are fused by ordinal rank (§8.1), so a
BM25 weight change only moves the score if it reorders the hits — on a corpus this
small, flat weights do not.
The abstention F1 in that run is 0 because `MIN_SCORE` is unset by default, so
the two `abstain` queries still return their best (wrong) match. The calibration

"""Kick off the eval harness (§10) without blocking the request.
`run_eval_cli` drives its own `asyncio.run(...)`, so it cannot be
awaited from inside this request's event loop. FastAPI's
BackgroundTasks runs a plain (non-async) callable in a worker thread
via `run_in_threadpool`, which gives it a loop-free thread to call
`asyncio.run` from and keeps the response fast.
Both the query set and the report live on the data volume, not in the
working directory: the pod runs with `readOnlyRootFilesystem: true`
(§13a.3), so a relative `eval/results/...` path would fail at the write
with nothing but a log line to show for it.
