Correctness
- /api/remote never recorded source.created, so URL, GitHub and connector
sources had a source.deleted with no matching creation. All three creation
paths now go through one _audit_source_created helper.
- The prompt-cache rate divided cached tokens by a whole bucket's prompt
tokens. A bucket is a day and mixes calls whose provider reports a cache
breakdown with calls whose provider does not, so filtering buckets in the
client could not separate them and the rate was understated by however much
traffic ran on a non-reporting provider. The denominator is now computed in
SQL over the reporting rows.
- The outcome pill matched values nothing writes. Guardrails emit triggered /
not_evaluated and the device feed emits dispatched; the map had blocked /
denied / allowed, so a guardrail that fired rendered neutral grey -- the one
signal the merged feed exists to surface. Fixtures were seeding the
fictional values, so the tests passed on it too.
- Stream duration_ms timed the consumer. stream_token_usage is a generator,
so start-to-exhaustion includes the agent loop's tool handling and the SSE
client's pace; a slow browser recorded ~30s for a sub-second call. It now
accumulates only the time spent inside next().
Safety
- Activity filters failed open: an unknown facet or unparseable timestamp was
dropped, and no filter means every row, so a typo widened an audit view and
on the export streamed the full history. Both are now a 400.
- The search term was interpolated into an ILIKE pattern, so "100%" matched
everything and "q1_report" matched more than it should. Escaped.
- 0034 set actor_id NOT NULL with no default. A previous-release process
inserting mid-rollout would raise, and in admin/routes.py that insert shares
the request transaction, so a role grant beside it would roll back too.
Noise and dead code
- The per-user panel is a security panel: data-plane events file under the
actor, so an active account's routine deletes pushed a denied login out of
the 20-row window. It now excludes them; the Activity tab shows everything.
- device_audit_log had no created_at-leading index, so the merged feed
sequentially scanned that branch every page (migration 0036).
- conversation.deleted_all no longer records when nothing was deleted, and
agent.updated no longer records an empty field list.
- Dropped by_model from /admin/usage (no consumer; an extra aggregate per page
load), the duplicate filter surface on AuthEventsRepository that nothing
called, and the unreachable FLOW_LABELS.schedule entry.
- Type hints on record_event's conn and the remaining unannotated helpers.
The wrappers in docsgpt/usage.py already measured how long each call took --
for the llm_gen_finished / llm_stream_finished log lines -- and then threw the
number away. Nothing in the schema recorded it, so an operator could see what
an instance spent but never how slow it was.
Adds token_usage.duration_ms and token_usage.ttft_ms, and threads the
measurements the wrappers already take into the insert. The stream wrapper now
also stamps the moment of the first yielded chunk.
Both columns are nullable, and deliberately so: ttft_ms is NULL for a
non-streaming call and for a stream that failed before yielding anything, and
every row written before this migration is NULL too. A 0 there would drag a
p50 toward an instant first token that never happened.
