feat(usage): count unpriced attempts in the daily rollup; v2.30.0 - #241
Conversation
An attempt with unknown cost added 0 to both cost columns, so unpriced traffic read as
free. usage_attempt_daily_v2 gains a nullable unpriced_attempts (1 per unknown-cost
attempt that used tokens; NULL = not measured, never back-filled), carried in the
contribution payload and summed by a per-kind upsert. usage_history_state.unpriced_since is
written (insert-or-update; the v2 row is created lazily) as the day after the migration.
The read path projects the measure from all four historySource parts, including the
receipts query that answers today, and reports unpriced: { attempts, since } on totals and
breakdown rows; a window wholly before since reads null, never 0. Migration
0035_unpriced_attempts (renumbered after #221's 0034).

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The raw totals query returns 0 for a window that lies wholly before unpriced_since.
The raw unpricedAttempts aggregate is count(*) filter (...). count never returns NULL. If a raw-only window, such as ?window=today on migration day, ends before since, the API returns attempts: 0 and not null. This breaks the contract in UsageUnpriced and in the docs. historySums handles the same case with a lastDay check, so the two read paths now give different results. The API rollup also turns a raw 0 combined with a history null into 0.
Add the same window check here. The window's last touched day comes from window.to - 1ms. If that day is before since, return null.
Proposed fix
const unpricedAttemptsFor = (window: UsageWindow) => {
const lastDay = new Date(window.to.getTime() - 1).toISOString().slice(0, 10)
return sql<number | null>`(case when ${unpricedSinceDate} > ${lastDay}::date then null else count(*) filter (where ...) end)::float8`
}Build the aggregates for each window in totals and breakdown.

Review summary — 35 file(s), 9 finding(s).
Critical 0 · Major 0 · Minor 9 · Nit 0
db-usage-unpriced-data-layer
Adds an unpriced_attempts measure to the daily usage rollup and history repository read path. Migration 0035 adds the columns and seeds unpriced_since; the read path masks pre-since days to null.
concern-tests
Server-side unpriced behaviour is pinned by real-HTTP tests on both serving paths plus the since passthrough; the only gap is client-side — the new addTotals unpriced merge and wire parse ship with no test.
New suites pin storage, since-gating, boundaries, repair and read paths tightly; two minor gaps: the token-less success combination is unpinned, and the state-row backup in the delete test selects unfiltered.
concern-api-contract
No contract surface breaks: the new unpriced wire field, the two nullable columns and the optional contribution-payload key are additive with a documented rollback path, and every reshaped signature (historySums(window), narrowed read returns) left no caller unupdated.
Contract verdict: the pinned read shape ({ attempts, since } with the 'infinity' sentinel and null-never-0 pre-since windows) is coherent across storage, receipts and breakdown and breaks no existing caller; one minor fragility in the state-row restore test.
concern-style-nits
Style concern: no misleading names, stale comments or dead code; two nits — a thrice-repeated magic slice(0, 9) and a last-write-wins since in the web totals fold that trusts a comment instead of checking.
Style verdict: both new test files read clearly and their comments match the behavior they assert; only nits are an unfiltered state-row save/restore and a twice-duplicated legacy payload literal.
api-usage-read (handoff)
Counts token-using unpriced attempts in the usage read and deletes the api-side two-table stitch (aggregate.ts, splitWindow/sumTotals) in favor of the db-side projection; version 2.30.0. Logic is coherent; one gap — no read-path test pins the documented legacy/request-table NULL projection.
web-usage-client (handoff)
Web client passes the new unpriced field through cleanly: null-propagating sums in addTotals, pass-through in parseTotals, EMPTY_TOTALS sentinel — consistent with the stated server rule. Risk: the client-side mapping and null branch ship with zero web-side test coverage.
db-usage-unpriced-data-layer (handoff)
Adds the unpriced-attempts measure end to end — migration 0035, payloads, additive upsert, since-gated reads — with null-means-unmeasured held consistently and tests pinning counting, gating and repair. Gap: the migration's upgrade-only ON CONFLICT branch is never executed by any test.
No findings from: api-usage-read, web-usage-client, release-bump-docs, concern-security.

minor · test The HTTP read-path tests cover only the receipts (today) and v2 closed-day projections; no test drives a legacy- or request-table-sourced window, so the documented NULL projection for those parts is unpinned and a regression reading them as 0 passes CI (kb:review/learnings). Add a usage_daily-sourced closed-day case asserting unpriced.attempts === null.

The describe block at head (lines 44-94) still contains only the receipts (today) and v2 closed-day tests; no usage_daily-sourced closed-day case asserting unpriced.attempts === null was added. The diffs since the finding touch the migration seed and a different test file, not this one.

minor · test No apps/web test pins the new unpriced mapping or addTotals's null-propagation branch, and the ui-geometry usage fixture is untyped (kb:review/pr-240), so dropping or mis-nulling the field ships green. Add a bun-test unit over parseTotals/addTotals asserting both-null → null, one-null → treated as 0, and since carried.

The diff since the finding only touches a db migration and a db integration test; apps/web/src/lib/api/usage-wire.ts is unchanged, and parseTotals still passes unpriced through as a blind passthrough (line 145) with no bun-test pinning the both-null→null, one-null→0, or since-carried behavior.

minor · test The new client-side addTotals unpriced merge (all-null stays null, measured rows coalesce to a sum) and the unpriced parse in usage-wire.ts ship with no test, so a regression that turns a pre-measurement null into a false 0 passes CI — the coverage-gap class of kb:review/pr-152. Add a unit test over sumTotals pinning both the all-null and the mixed null+measured outcomes.

Re-checked at 262533414d43: still open at apps/web/src/lib/api/usage.ts:256. The unpriced coalescing in addTotals is still untested: the diff only edited a SQL migration and a server-side integration test in packages/db/test/integration/usage-unpriced.test.ts. No unit test over sumTotals (line 207) pins the all-null or mixed null+measured outcomes, so the regression window the finding flagged remains open.

minor · test The ON CONFLICT branch runs only on upgraded installs where the v2 state row predates 0035; the fresh-DB fixture never executes it, so a regression leaves unpriced_since NULL on every upgrade and the measure dies silently (kb:review/learnings). Add a case that nulls unpriced_since on an existing v2 row and re-runs this statement, asserting it is set.

Re-checked at 262533414d43: still open at packages/db/test/integration/usage-unpriced.test.ts:58. The only test-file change adds a WHERE clause to an existing SELECT; no new test was added that nulls unpriced_since on a pre-existing v2 row and re-runs the migration to assert the ON CONFLICT branch sets it. The defect remains.

minor · bug ON CONFLICT coalesce(table.col, 0) + excluded.col for unpriced_attempts returns NULL when excluded.col is NULL, nullifying any existing non-NULL value. The 'not measured wins' comment assumes pre-measure rows only exist pre-since, which isn't enforced anywhere — a repair that pulled only pre-measure rows for an already-measured day would silently lose the measurement.

concern-tests
Four test gaps in the new unpriced measure: HTTP pre-since null projection and legacy usageDaily source path unpinned, web parseTotals and addTotals unpriced merge uncovered.
Two coverage gaps the prior reviewers' flagged regressions would slip past: the unit test only exercises token-less failure, and the integration test never proves a pre-measure NULL repair preserves an existing measurement.
concern-api-contract
The unpriced widening on the wire and the read-repository narrow are by design, but the upsert's coalesce(existing,0)+excluded actively writes NULL over measured unpriced_attempts whenever the new sum is NULL — a one-way corruption that violates the "NULL = not measured" contract the new field…
No new contract violations in the integration/unit test slice; the assertions pin the {attempts, since} shape, NULL pre-measure semantics, and idempotency correctly.

Two nits: a magic-number slice and an incomplete comment.
Test files use clear names and accurate docstrings; no comment overpromises a guarantee the assertions don't pin down.

major · bug The unpriced_attempts ON CONFLICT branch computes coalesce(table.col, 0) + excluded.col, which evaluates to NULL in standard SQL whenever excluded.col is NULL — and it is NULL whenever the group sums any payload that lacks the field (every pre-2.30.0 receipt, every request-terminal payload).

What
Unpriced traffic is counted instead of reading as $0. The usage API reports
unpriced: { attempts, since }on totals and breakdown rows.Why
An attempt whose cost basis is
unknownadded 0 to both cost columns of the daily rollup (usage-contribution-values.ts), so spend on unpriced models looked free.Changes
usage_attempt_daily_v2.unpriced_attempts bigint, nullable. NULL means not measured, and nothing is back-filled.grain(), so request rows don't carry it.usage_history_state.unpriced_since dateis written by insert-or-update as the day after the migration runs. Thev2row is created lazily, so an UPDATE alone would leave a fresh install without one.router_cost_basis_total, which also counts them; the docs say so.historySourceprojects the measure from all four parts: the v2 attempt table, NULL for the legacy and request tables, and the receipts query that answerstoday.
