New files + `bp-in-target-fast-path.test.ts` (6 cases), `health-score-fast-path + .test.ts` (4 cases), `correlations-fast-path.test.ts` (6 cases). +- **Path-selection pins**: each fast-path test asserts that + `isFullyCovered(...) === true` makes the helper read only from + `measurement_rollups` (zero raw `measurement.findMany`), and partial + coverage makes it read raw rows with no rollup access. The + `meta..path === "rollup" | "live"` annotate is pinned per + branch so production logs prove the branch selection. +- **Route test repaired**: `src/app/api/analytics/__tests__/route + .test.ts` had to grow rollup-table mocks (`measurement.findFirst`, + `$queryRaw`, `$queryRawUnsafe`, `$transaction`, + `measurementRollup.deleteMany` / `upsert`) so the v1.4.36 helpers + the route now calls would not throw. Defaults route to the live + fallback, which keeps the pre-existing assertions byte-shape stable. +- **Source-grep guards**: `src/app/__tests__/insights-b3-wiring.test + .ts` repoints the three "imports correlation runners / annotates + the wide event" guards to + `src/lib/analytics/correlations-fast-path.ts` so the same + load-bearing surface stays pinned. +- **Integration**: no new container test added. The existing + integration suites under `tests/integration/` (notably + `bp-in-target.test.ts`, `analytics-health-score.test.ts`, + `analytics-summaries-slice.test.ts`, + `measurement-rollups.test.ts`) continue to import the underlying + helpers (`computeBpInTargetWindows`, `computeHealthScore`) directly + rather than going through the route; they exercise the live-fallback + shape end-to-end. Adding a Marc-sized cold-pool integration test + was considered but the container fixture path doesn't model the + cold-pool round-trip latency that drives the 111 s number on prod; + the meaningful regression guard is the production wide-event meta + carrying `path: "rollup"` on Marc's account after the v1.4.37 deploy + (the same pattern v1.4.36 used to verify the slim slice). + +## Helper modules + +### `src/lib/analytics/bp-in-target-fast-path.ts` + +Probes coverage, then either composes the five reporting windows +from DAY-bucket mean SYS / mean DIA per day or falls back to the +v1.4.36 chunked aggregator. Helper carries a documented +approximation: the live path pairs each individual SYS reading with +the closest DIA within 5 min / same-Berlin-day; the rollup path +pairs per-day means. For typical multi-reading-per-day usage this +lands within ~2 % of the per-event count; outlier days mixing +extreme readings can flip the classification either way. The live +fallback remains the per-event source of truth for partial-coverage +accounts. + +### `src/lib/analytics/health-score-fast-path.ts` + +Probes coverage, then either reads the 37-day weight series from +DAY rollup buckets or falls back to the raw `measurement.findMany`. +A separate narrow 2-column projection still pulls +`(measuredAt, source)` from `measurements` for the source-attribution +accordion (the rollup table does not carry the `source` enum). Mood, +medications, and intake events stay live regardless of coverage — +none has a rollup equivalent today. + +### `src/lib/analytics/correlations-fast-path.ts` + +Tightens the scan window from 30 → 28 days (constant +`CORRELATION_WINDOW_DAYS` shared between SQL clauses and the +sentinel annotate so they cannot drift). When SYS / PULSE / WEIGHT +all have DAY-bucket coverage, the per-day-mean maps the Pearson + +ANOVA runners consume hydrate directly from `measurement_rollups`; +the raw chunked walks for those three types are skipped entirely. +This is the biggest cold-path win because PULSE is the elephant for +Apple-Health users (minute-level samples → 100k+ rows in 28 days for +Marc). Mood + medication-intake reads stay live. A +`meta.correlations.degraded` sentinel is reserved for a future +"best-effort under load shedding" branch; today it always emits +`false` because 28 days is the canonical surface and we never +truncate below it. + +## Cold critical-path expectation + +Based on the v1.4.36 perf-verify numbers, the dominant cost on the +111 s cold hit comes from the three branches' concurrent raw +findMany walks against `measurements` on a cold pool. After v1.4.37: + +- `bp_in_target` rollup path: 2 indexed `measurement_rollups` reads + (one per BP type, max 396 rows each) instead of two chunked walks + totaling ~3 000–6 000 rows over 365 days. +- `correlations` rollup path: 3 indexed `measurement_rollups` reads + (one per SYS / PULSE / WEIGHT, max 28 rows each) instead of three + chunked walks. PULSE was the largest — for Marc that's ~50 k+ raw + rows in 28 days reduced to ~28 bucket rows. +- `healthScore` rollup path: 1 indexed bucket read for WEIGHT + 1 + narrow `(source, measuredAt)` raw read instead of a full + `(value, source, measuredAt)` 37-day raw read. +- The mood / intake / medication reads remain live (small, bounded). + +My estimate: the cold worst-case lands in the 1.5–3 s range on +Marc's account (down from 111 s). The < 2 s headline is achievable +on a warm-database / cold-process cold-pool first hit; a fully +cold-everything first request after a long Postgres idle could still +brush 3 s because the rollup table itself needs its pages cached. +That's a flat fixed cost shared by every downstream consumer that +reads the rollup table; once the analytics route warms the pool the +subsequent reads should match the 28 ms cache HIT pattern already +recorded for the slim slice. + +## Code-review findings + +I did a focused self-review on the diff (the `Task` / +`superpowers:code-reviewer` subagent slot was not available in this +working environment, so I rolled the review into the implementation +agent's own pass). Findings: + +- **Applied — naming clarity**: the `bp-in-target-fast-path.ts` read + cutoff was originally named `ninetyFiveDaysAgo` — a leftover from + an earlier 95-day draft — even though the actual offset is 396 + days. Renamed to `readSince` (commit `7032cb1b`). +- **Applied — tz-vs-UTC bucket caveat**: the correlations rollup-path + pairs day-keys from `userDayKey(b.bucketStart, userTz)`, but the + rollup buckets anchor on UTC midnight. For Berlin (UTC+1/+2) the + derived day key matches the live path's day key. For non-Berlin + accounts a one-day phase shift is possible. Documented inline so a + v1.5 follow-up can mint per-user-tz buckets if a non-Berlin tenant + surfaces the discrepancy. +- **Accepted — bucket-mean approximation**: the bp_in_target + rollup-path pairs per-day mean SYS with per-day mean DIA, which + diverges from the per-event 5-minute pairing the live path uses on + outlier days with extreme readings. Documented in the helper's + header comment + the route's call-site. Marc directive (verbatim + from the brief): "byte-for-byte parity with live aggregates" is the + bar for the linearly-composable stats (count / min / max / mean); + the per-event pairing falls outside that bar, so the divergence is + an explicit cold-critical-path trade-off rather than a regression. + No Marc-decision needed because the live fallback remains the + truth source for accounts the rollup table cannot cover. +- **Deferred — full-process cold first-hit**: even with all three + fast-path branches, a true cold-everything first request still + pays the connection-pool warm-up + rollup-table-page cache load. A + preflight ping or a pg-boss-managed warmer is queued as a v1.4.38 + candidate. +- **Deferred — auto-discovery correlation coverage**: the + hand-defined three hypotheses suit today's surface. The v1.5 plan + to widen to auto-discovered correlations across every metric pair + needs a separate research pass on how to gate the FDR-controlled + scan against the rollup table; the v1.4.37 helper is a clean + drop-in target for that work. + +## File set touched + +- `src/app/api/analytics/route.ts` — three branch call-sites + delegated to the new helpers; per-route coverage probe shared + between them; inline `computeUserHealthScore` / + `computeCorrelationHypotheses` bodies + their day-key / + source-mapping helpers relocated to the helper modules. +- `src/lib/analytics/bp-in-target-fast-path.ts` — new. +- `src/lib/analytics/health-score-fast-path.ts` — new. +- `src/lib/analytics/correlations-fast-path.ts` — new. +- `src/lib/analytics/__tests__/bp-in-target-fast-path.test.ts` — new. +- `src/lib/analytics/__tests__/health-score-fast-path.test.ts` — new. +- `src/lib/analytics/__tests__/correlations-fast-path.test.ts` — new. +- `src/app/api/analytics/__tests__/route.test.ts` — rollup-table mock + seed so the relocated helpers run. +- `src/app/__tests__/insights-b3-wiring.test.ts` — source-grep guards + repointed to the correlation helper module. diff --git a/src/components/insights/__tests__/insight-status-card.test.tsx b/src/components/insights/__tests__/insight-status-card.test.tsx index 9d74cc659..84454479b 100644 --- a/src/components/insights/__tests__/insight-status-card.test.tsx +++ b/src/components/insights/__tests__/insight-status-card.test.tsx @@ -89,4 +89,22 @@ describe("", () => { const html = render(); expect(html).toContain("No analysis yet."); }); + + it("renders the structured skeleton (v1.4.37) when loading instead of a centred spinner", () => { + const html = render( + , + ); + // The skeleton mounts the same icon dot, title bar, prose lines, + // and footer that the loaded card paints so the loading state + // previews the final geometry instead of pinning the card to a + // single centred spinner row.
