Workspace analytics + per-model inference token usage - #241
Merged
Conversation
Adds two workspace analytics endpoints and Tier-3 inference token
accounting.
Endpoints (ViewWorkspace-gated):
- GET /workspaces/{ws}/analytics/ — snapshot: storage by file kind,
run health (status mix, error rate, avg/p95 durations), and per-model
token usage.
- GET /workspaces/{ws}/analytics/runs/timeseries/?from&to — dense daily
run series (runs/day, error rate, durations, tokens); every day in the
window is present, capped at 366 days.
Token usage (counts only, no pricing):
- New workspace_pipeline_run_usage child table, one row per (run, model);
input/output/total tokens are stored independently (a provider's total
is not necessarily input + output). The full per-recognizer report is
kept in run metadata for drill-down.
- The detection worker extracts per-model usage from the engine Audit and
persists it with the run's audit-file row and Analyzed transition in a
single transaction; the (non-transactional) audit object is written
first so a rollback leaves at worst an orphan blob, never a dangling row.
Also: PipelineRunStatus::OUTCOMES / is_outcome() for the error-rate basis
(completed or failed, excluding cancelled).

If the caller transaction rolls back after
store.put, the object has noworkspace_filesrow. The retention reaper cannot discover that object, so the stated retention cleanup does not occur. Repeated transaction failures can accumulate encrypted audit objects indefinitely.Track staged objects in durable storage for reconciliation, or add object-store lifecycle cleanup that does not depend on a database row.

- Around line 153-158: Update the documentation for the analytics query near
`RunTimeSeries` in `crates/nvisy-postgres/src/query/analytics.rs` lines 153-158
to state that it returns only days with runs and that
`RunTimeSeries::from_window` performs gap-filling; remove claims about dense
rows, `generate_series`, and `runs = 0`. Also update the cap rationale in
`crates/nvisy-server/src/handler/request/analytics.rs` lines 10-13 to reference
the response point count instead of `generate_series`.
- Around line 181-191: Update the total_bytes conversion in the StorageByKind
mapping to avoid using i64::MAX for NULL or failed BigDecimal conversions; use
the established safe zero/default behavior so WorkspaceAnalytics::from_parts can
sum per-kind totals without overflow.
- Around line 226-231: Qualify the run timestamp columns in the raw SQL
fragments used by run_durations and runs_by_day, including duration_secs and
p95, by referencing workspace_pipeline_runs.started_at and
workspace_pipeline_runs.completed_at. Apply the same qualification to every
started_at/completed_at reference in those fragments while preserving the
existing calculations.
In `@crates/nvisy-postgres/src/types/json/pipeline_run_metadata.rs`:
- Around line 20-26: Update the documentation comment for the usage field to
state that aggregate token counts are stored in and driven by the
workspace_pipeline_run_usage table, replacing the incorrect run-row
input_tokens/output_tokens reference. Keep the rest of the usage description
unchanged.
In `@crates/nvisy-server/src/handler/analytics.rs`:
- Around line 52-54: Update the endpoint description in the analytics handler to
mention the response’s token usage data, including workspace totals and the
per-model breakdown, alongside the existing stored-file and pipeline-run health
details.
In `@crates/nvisy-server/src/handler/request/analytics.rs`:
- Around line 77-81: Update AnalyticsRequest::to_timestamp to return the first
instant after self.to and revise its documentation to describe an exclusive
upper bound. In crates/nvisy-postgres/src/query/analytics.rs at lines 332-333
and 374-375, update both run-count and token filters to use
runs::started_at.lt(to); these sibling sites require direct changes.
In `@crates/nvisy-server/src/service/detection/worker.rs`:
- Around line 300-305: Update the metadata construction around RunMetadata so it
preserves the existing run metadata, including tags, before setting usage.
Decode or clone the current metadata, assign the cloned usage report, and encode
the merged RunMetadata instead of starting from Default.
- Around line 311-325: Update the completion transaction in the worker around
conn.transaction to retain the claim token and verify that the worker still owns
the run under the transaction lock before creating the audit file, calling
record_run_usage, or updating status. Make update_workspace_pipeline_run
conditional on the retained token, and exit without inserting usage or marking
the run analyzed when ownership is stale.
In `@migrations/2026-01-19-045014_pipelines/up.sql`:
- Around line 235-240: Update the usage-row uniqueness constraint near
workspace_pipeline_run_usage_run_model_key so identity includes run_id, model,
and a NULL-normalized version, allowing distinct versions while treating NULL
versions as the same identity. Preserve the existing model and version
validation constraints.

Included review availability: Your plan provides up to 10 included reviews per hour; 9 remain after this review.
Correctness: - Time-series window upper bound is now exclusive (first instant of the day after `to`); run-count and token filters use `started_at < to`, so the final day of the window is no longer dropped. Covered by new tests. - Usage-row identity is (run, model, version) via a unique index that normalizes a NULL version, so a run using one model at two versions no longer fails the batch insert on a (run, model) collision. - Reclaim staged audit objects when the finalize transaction does not commit (stale claim or error), so a rolled-back write leaves no object the row-driven reaper can never find. - Fence the analyze finalize on the held claim: a run re-claimed past the lease by another worker rolls back instead of stamping over its work. - Preserve a run's existing metadata (tags, error) when writing usage instead of overwriting from Default. Robustness / clarity: - Read the two per-day grouped statements in one transaction (same snapshot); factored into helper fns. - Table-qualify run columns in the raw-SQL duration/percentile fragments. - Storage byte total falls back to 0 (not i64::MAX) on NULL/overflow. - day_start_utc returns a 400 instead of silently widening to UNIX_EPOCH. - Fix stale docs (generate_series, run-row token columns) and add token usage to the analytics endpoint description.

- Fail path is now claim-fenced too: fail_run takes an optional claim token; on the worker path a run is failed (and its failure broadcast / webhooked) only while the claim still holds, so a worker whose lease expired mid-analysis cannot fail a run another worker now owns. The handler enqueue-failed path passes None (no claim). Adds a guarded finalize_failed_run mirroring finalize_analyzed_run. - Read the two per-day statements in a read-only, repeatable-read transaction (a consistent snapshot without holding write locks). - Extract the shared run_day() day-bucket fragment so both daily queries bucket on identical SQL and cannot drift. - Drop the stale doc paragraph on stage_analyzed_document (it no longer inserts the row) and fold the retention rationale into the current one. - Add a boundary test accepting a window exactly at MAX_WINDOW_DAYS and tighten the reject test to cap + 1.

Force UTC in run_day.
date_trunc('day', timestamptz) uses the PostgreSQL session time zone. A non-UTC session can assign runs near midnight to the wrong UTC day and misalign gap-filled API points.
Proposed fix
fn run_day() -> diesel::expression::SqlLiteral<Timestamptz> {
- diesel::dsl::sql::<Timestamptz>("date_trunc('day', workspace_pipeline_runs.started_at)")
+ diesel::dsl::sql::<Timestamptz>(
+ "date_trunc('day', workspace_pipeline_runs.started_at AT TIME ZONE 'UTC') \

Count inclusive days when enforcing window limits.
to is inclusive. A window from January 1 through January 1 plus 366 days contains 367 daily points, but this test accepts it. The default to - 30 days range also produces 31 points. This exceeds the stated 366-day cap and 30-day default.
Subtract DEFAULT_WINDOW_DAYS - 1 for the default. Reject spans where days >= MAX_WINDOW_DAYS. Update this acceptance test to use MAX_WINDOW_DAYS - 1, and update the rejection test to use MAX_WINDOW_DAYS.

Update AnalyticsWindow::resolve to count both inclusive endpoints: default the
end date using DEFAULT_WINDOW_DAYS minus one, and reject spans when the computed
day difference is greater than or equal to MAX_WINDOW_DAYS. Adjust
accepts_window_exactly_at_the_cap to use MAX_WINDOW_DAYS minus one and
rejects_window_wider_than_the_cap to use MAX_WINDOW_DAYS.

Return whether the failure transition committed.
If update_workspace_pipeline_run fails on Line 154, this function still broadcasts Failed and emits the failure webhook. The run can remain Queued while external consumers receive a terminal failure event.
Also, crates/nvisy-server/src/service/detection/worker.rs sends PipelineRunFailed after this function returns. That notification is sent even when Lines 143-146 suppress a stale worker failure.
Make fail_run return false after every stale-claim or database-error path. Return true only after the update commits. Send the worker notification only when the result is true.

Update fail_run to return a boolean commit status: return false for stale claims
and every database-error path, and true only after the failure update succeeds.
In the worker flow around fail_run, emit PipelineRunFailed only when fail_run
returns true, preventing broadcasts and webhooks for uncommitted or stale
failures.
The snapshot endpoint fired four independent reads sequentially, so a write between them could make the parts disagree (a run counted in the status histogram but its tokens missing from the usage totals) — the same inconsistency the time series already avoids. - Replace the four public repository methods (storage_by_kind, runs_by_status, run_durations, usage_by_model) with one `snapshot` method that runs them in a single read-only, repeatable-read transaction and returns an `AnalyticsSnapshot`. The trait surface is now two methods (snapshot, runs_by_day), each composing private `load_*` helpers — matching the existing runs_by_day shape. - Response assembly takes the snapshot: `from_parts` -> `from_snapshot`. - Replace the anonymous generic load tuples with named `Queryable` row structs (StorageKindRow, UsageByModelRow); load RunStatusCount and RunDurations directly instead of via a tuple + map.

Run durations were exposed in seconds as f64 (avgDurationS / p95DurationS) while every other serialized duration in the API is milliseconds as i64 (webhooks' responseTimeMs, the usage table's duration_ms). Standardize on ms + i64 so a client never has to track which endpoint uses which unit. - Response DTOs: avg_duration_s / p95_duration_s (f64 seconds) -> avg_duration_ms / p95_duration_ms (i64 ms), on both the snapshot and the per-day series. - Query layer: RunDurations and RunDayPoint carry avg_ms / p95_ms (i64); the epoch-seconds are scaled by 1000 and rounded to bigint in SQL, so the value crosses the boundary already in the API unit and type. This also removes the old _seconds/_s naming split between the query and DTO layers. - Tests updated to ms; SQL validated against Postgres.
