* Extract session pipeline framework, refactor verification, add UsageProcessor skeleton
Pluggable framework under services/session_pipeline/ (contract + lib + per-processor
runner) so multiple processors can read /data/user_sessions/<key>/*.jsonl on their
own cadence with full failure isolation. Verification flow becomes the first plugin;
a no-op UsageProcessor reserves the second slot pending a separate brainstorm on
extraction logic + storage shape.
Schema v28→v29: rename session_extraction_state → session_processor_state with
composite PK (processor_name, session_file). Existing rows copied over with
processor_name='verification'; legacy table dropped. Migration is idempotent and
no-ops the copy step on fresh installs that came up at the new schema.
Endpoint: /api/admin/run-verification-detector replaced by parametrized
/api/admin/run-session-processor?processor=<name>. Audit action format follows.
Scheduler JOBS: verification-detector entry split into session-processor:verification
+ session-processor:usage. SCHEDULER_VERIFICATION_DETECTOR_INTERVAL retained for
operator compatibility (drives both cadence and health-check grace window);
SCHEDULER_USAGE_PROCESSOR_INTERVAL added.
* Address PR #232 review: scan dead branch + per-processor lock
- `SessionProcessorStateRepository.scan_unprocessed_for` dead else: both
branches surfaced every jsonl, the SELECT was unused, runner MD5-rehashed
every stable session per tick. Replaced with an mtime precheck — stable
sessions (mtime <= processed_at) are filtered at scan; modified files
still surface for the runner's authoritative `file_hash` invalidation.
Naive-local comparison matches the existing health-check idiom (DuckDB
TIMESTAMP strips tz on storage).
- Per-processor advisory lock around `_run_processor` in
`/api/admin/run-session-processor`. Scheduler tick + manual admin POST
could otherwise both run, both call create_evidence on overlapping
detections, and accumulate duplicate verification_evidence rows (the
dedup short-circuit only covers create+contradiction, not evidence per
ADR Decision 3). Non-blocking acquire → 409 Conflict on concurrent
invocation; release in finally so a runner exception doesn't wedge the
processor.
Tests: two new scan unit tests (mtime filter + post-mark mtime bump), 409
endpoint test, lock-released-on-exception test. Two existing tests updated
for the new "filtered at scan" stat shape (previously asserted skipped == 1,
now scanned == 0).
* Address PR #232 review #2: parallel scheduler tick + last_run on terminal state
Two pre-existing scaffold bugs in services/scheduler/__main__.py amplified
by adding more session-pipeline jobs:
1. Serial for-loop over jobs with synchronous httpx.post(timeout=900) — a
10-minute verification run blocked every other job (data-refresh,
health-check, usage, corporate-memory) for the whole window. The PR's
stated isolation guarantee held inside the runner but broke at the
scheduler dispatch layer.
2. last_run advanced only when _call_api returned True. Permanent-failure
jobs hot-looped on every tick (30s) instead of cadence (15min).
Fix: ThreadPoolExecutor.submit per due job + per-job in_flight set so a
long-running job can't be re-launched on subsequent ticks. last_run
advances unconditionally in finally; errors still surface via _call_api
logging + audit_log on the receiving side.
_run_job extracted to module-level for unit testing. New tests:
- TestRunJobBookkeeping: advances on success / failure / unhandled raise
- TestRunLoopParallelism: in_flight protection prevents duplicate
launches across ticks for a single slow job

Devin flagged that run_session_collector still had the same audit-skip
gap I fixed in run_verification_detector and run_corporate_memory in
the previous two rounds — a PermissionError walking /home, an OSError
on /data/user_sessions mkdir, or any other unhandled exception from
collector.run() would skip the audit_log row and only show in docker
logs.
Same try/except + unhandled_error pattern as the sibling endpoints.
All three LLM-pipeline run-* endpoints now record their failures the
same way; /admin/scheduler-runs sees them. Regression test in
tests/test_admin_run_endpoints.py::TestRunSessionCollector::test_unhandled_exception_still_audits.
Devin flagged that run_corporate_memory still had the same audit-skip
gap I just fixed in run_verification_detector — if collect_all() throws
anything other than the already-translated ValueError (DuckDB lock,
network blip, unexpected SDK error), the audit_log row was never
written and /admin/scheduler-runs missed the failure.
Same try/except + unhandled_error pattern as the verification_detector
fix from 4c4dfee8. Regression test in
tests/test_admin_run_endpoints.py::TestRunCorporateMemory::test_unhandled_exception_still_audits.
run_session_collector called collector.main() which did argparse.parse_args()
on uvicorn's sys.argv (['app.main:app', '--host', ...]) → sys.exit(2) →
SystemExit(2), which inherits from BaseException, escapes FastAPI handlers,
and propagates through the thread pool. Every scheduler tick that fired the
endpoint either 500-ed or risked killing the uvicorn worker.
services/session_collector/collector.py now exposes run(dry_run, verbose)
that returns (rc, stats); main() is a thin CLI shim that parses argv and
delegates. The admin endpoint calls run() directly and audit-logs the
per-run stats (users_processed, files_copied, files_skipped) instead of
just the rc. Three regression tests in TestRunHelper.
Closes Devin Review finding on app/api/admin.py:2819 (#179).
The session-collector, verification-detector, and corporate-memory
services now run on the same scheduler-v2 model that already drives
data-refresh, health-check, script-runner, and marketplaces:
- New admin endpoints in app/api/admin.py:
POST /api/admin/run-session-collector
POST /api/admin/run-verification-detector
POST /api/admin/run-corporate-memory
All admin-gated, sync-def (FastAPI thread pool), with one audit row
per invocation. Same single-writer-of-system.duckdb pattern as the
existing /api/marketplaces/sync-all job.
- services/scheduler/__main__.py JOBS gains three entries with offset
cadences (10m / 15m / 17m, all coprime modulo the 30s tick) so the
three LLM-backed jobs don't fire on the same tick and stack their
API + DB load.
- The verification-detector endpoint surfaces the LLM factory's
fail-fast ValueError as HTTP 500 with the actionable message,
preserving the no-silent-skip contract from the previous commit.
Tests:
- tests/test_admin_run_endpoints.py covers admin gating + scheduler
registration + endpoint contract.
- tests/test_scheduler_sidecar.py existing tests continue to pass.
