🟢 Low brainlayer/enrichment_controller.py:495
The per_chunk_delay sleep at lines 517-518 only staggers task submission to the thread pool, not API call execution. With ENRICH_CONCURRENCY=10 workers running concurrently, the actual Gemini request rate can spike to ~10× the intended rate_per_second limit. With the default 5.0 RPS this yields ~50 RPS at the API, risking quota exhaustion or rate-limit errors. Consider throttling at the point of API call (e.g., semaphore-permit acquisition around client.models.generate_content) so the limit bounds concurrent execution, not just submission pacing.

Inline comments:
In `@src/brainlayer/enrichment_controller.py`:
- Around line 502-518: The bug is that duplicates in the same candidates batch
can both observe is_duplicate=False because all tasks are queued before any
content_hash writes; modify the submission loop in the ThreadPoolExecutor block
so you pre-deduplicate or "reserve" hashes before calling executor.submit:
compute a per-batch seen set (e.g., seen_hashes) for the candidate content_hash
(or call a reserve_content_hash(content_hash) helper) and skip or mark
is_duplicate=True for subsequent identical chunks prior to submit; ensure this
change touches the loop that builds futures (references: candidates,
_enrich_single_chunk, is_duplicate, futures, per_chunk_delay,
ENRICH_CONCURRENCY) so only one in-flight worker exists per content hash.
- Around line 520-532: The loop that handles futures in enrich_realtime calls
_apply_enrichment outside any exception handling so a DB write error (e.g.,
apsw.BusyError) will abort the whole run; wrap the call to
_apply_enrichment(chunk, data, store) inside a try/except that catches general
exceptions and specifically handles SQLITE_BUSY/apsw.BusyError with retry logic
(backoff and limited retries) and ensures the worker uses its own DB connection;
on failure increment result.failed, append the error to result.errors with
f"{chunk['id']}: {err}", and call _emit_enrichment_error("realtime",
chunk["id"], str(err))—preserve existing result.enriched increment only on
success.
- Line 47: ENRICH_CONCURRENCY should be validated and defaulted instead of
directly casting the env var; change the module-level assignment for
ENRICH_CONCURRENCY to parse os.environ.get("BRAINLAYER_ENRICH_CONCURRENCY")
inside a try/except, ensure the parsed value is an int > 0, and fall back to 10
if parsing fails or the value is <= 0; also emit a warning or info via the
existing logger when falling back so callers constructing ThreadPoolExecutor
using ENRICH_CONCURRENCY will never receive invalid (non-positive) values.
In `@tests/test_concurrent_enrichment.py`:
- Around line 29-85: The test for enrich_realtime currently only verifies that
two chunks are processed sequentially, not enforcing concurrency. To properly
test concurrency in enrich_realtime, modify the FakeClient or the mocked methods
to use a threading.Barrier or Event to block inside generate_content until both
chunks have been submitted. This will ensure multiple submit calls happen before
any apply runs, exposing concurrency behavior. Update the test to assert that
processing truly overlaps or that _apply_enrichment is called only after
multiple concurrent submissions, thus exercising the concurrency contract
introduced by enrich_realtime.

499-500: No changes needed. The code already uses per-thread readonly connections for duplicate checks. The_read_cursor()method invector_store.pyreturns a cursor from_get_read_conn(), which usesthreading.local()to maintain separate connections per worker thread. Each thread creates its own readonly connection with a 30-second busy timeout, ensuring workers do not share the main store connection.

Validate BRAINLAYER_ENRICH_CONCURRENCY before using it.
A non-integer value now raises during module import, and 0/negative values fail later when ThreadPoolExecutor is constructed. This should parse as a positive integer with a fallback instead of crashing the controller on a bad env var.

Same-batch duplicate chunks can now double-hit Gemini.
All candidates are queued before any content_hash write happens, so two identical chunks in the same candidates list can both observe is_duplicate=False and both call the API. The old sequential flow would let the second copy see the first write and skip. Reserve hashes before submit() (or pre-deduplicate the batch) so only one in-flight worker exists per content hash.

One apply/write failure now aborts the whole realtime run.
_enrich_single_chunk() normalizes API/prompt failures into per-chunk statuses, but _apply_enrichment() is now outside any try/except. A single apsw.BusyError or other DB write failure will raise out of enrich_realtime(), skip the remaining futures, and suppress the completion event instead of incrementing result.failed.

This test still passes if enrich_realtime() regresses to a sequential loop.
The assertions only prove that two chunks are eventually processed. They do not prove overlap, parallel submission, or catch the same-batch duplicate race that this refactor introduces. Please gate the fake client with a threading.Barrier/Event pair (or assert multiple submit() calls happen before the first apply) so the PR’s concurrency contract is actually exercised.
As per coding guidelines: "Flag risky DB or concurrency changes explicitly and do not hand-wave lock behavior".

In `@tests/test_concurrent_enrichment.py` around lines 29 - 85, The test for
enrich_realtime currently only verifies that two chunks are processed
sequentially, not enforcing concurrency. To properly test concurrency in
enrich_realtime, modify the FakeClient or the mocked methods to use a
threading.Barrier or Event to block inside generate_content until both chunks
have been submitted. This will ensure multiple submit calls happen before any
apply runs, exposing concurrency behavior. Update the test to assert that
processing truly overlaps or that _apply_enrichment is called only after
multiple concurrent submissions, thus exercising the concurrency contract
introduced by enrich_realtime.

550-554:⚠️ Potential issue | 🟠 MajorFix xfail on latency SLO test — but the proposed solution won't work in CI
The concern is valid: without
xfail_strict=truein pytest config, this unconditional xfail allows assertion failures to silently pass in CI. However, the proposed solution usesos.getenv("CI") == "true", which GitHub Actions does not set; the condition would always be False.Better alternatives:
- Use
os.getenv("GITHUB_ACTIONS") == "true"instead, or- Enable
xfail_strict=trueinpyproject.tomlunder[tool.pytest.ini_options]to catch unexpected passes, or- Remove the xfail marker entirely — the other two latency tests (
test_deep_mode_under_500ms,test_entity_query_under_500ms) manage without it.Also: register the
livemarker inpyproject.toml:markersto avoid unregistered-marker warnings.🤖 Prompt for AI Agents

Learning: In `src/brainlayer/enrichment_controller.py`, the `parallel` parameter in `enrich_local()` is intentionally kept in the function signature (currently unused, suppressed with `# noqa: ARG001`) for API stability. Parallel local enrichment via a thread pool or process pool is planned for a future iteration. Do not flag this as dead code requiring removal.

Timestamp: 2026-04-04T15:22:02.740Z
Learning: In `hooks/brainlayer-prompt-search.py` (Python), `record_injection_event()` is explicitly best-effort telemetry: silent `except sqlite3.Error: pass` is intentional — table non-existence or lock failures are acceptable silent failures. `sqlite3.connect(timeout=2)` is the file-open timeout; `PRAGMA busy_timeout` governs per-statement lock-wait. The `DEADLINE_MS` (450ms) guard applies only to the FTS search phase, not to this side-channel write.

Profiling showed each enrichment chunk takes ~1.8s (1.0s API + 0.8s DB write), but we're only using 30 RPM of 10,000 RPM available. Concurrent API calls unlock the remaining capacity.
