Built fresh per turn by +`src/lib/ai/coach/snapshot.ts`. Every number in a Coach reply must +come from a snapshot field (GROUND RULE 1, 7). The snapshot carries +metric aggregates, `timeline.recent` (14-day day-level), and +`timeline.weekly` (ISO-week buckets for older days), plus optional +`weeklyContext.glp1` for GLP-1-tracked users. + +**Coach prompt versioning** — `PROMPT_VERSION = "4.25.0"` in +`src/lib/ai/prompts/insight-generator.ts`. Stamped on every +`RecommendationFeedback` + `CoachMessage` row. Bumped per system- +prompt change. See `08-locked-contracts.md` §9.2. + +**Codex** — ChatGPT OAuth provider (Marc's ChatGPT subscription). +Stored on `User.codexAccessTokenEncrypted` etc. Web-only path; iOS +does not participate. See `12-ai-coach.md` (Agent D). + +**Coolify** — Self-host deployment platform HealthLog runs on. Multi- +arch Docker image builds at GHCR. iOS team interacts with Coolify only +through staging URLs — no direct deploy access. + +--- + +## D + +**Drift-guard test** — Test that asserts a hand-curated artefact has +not silently changed (OpenAPI spec, safety-contract YAML parity, +system-prompt headings). Hard-fails CI. See `08-locked-contracts.md` +§10. + +**DLQ** — "Dead-letter queue". HealthLog's pg-boss does not use a +separate DLQ table; failed jobs flip to `state = 'failed'` in +`pgboss.job`. Operators surface via Admin → System Status. + +--- + +## E + +**Evidence block** — The `---KEYVALUES---` / `---END---` sentinel +section the Coach appends to its reply (GROUND RULE 2). iOS parser +extracts it and renders as the "What I'm looking at" collapsible +disclosure. Sentinels are LITERAL — never translated. See +`08-locked-contracts.md` §1. + +--- + +## G + +**GlitchTip** — Self-hosted Sentry-compatible error tracker. +HealthLog reports unhandled `apiHandler` errors fire-and-forget. Path +in URL is scrubbed before forwarding (no `?code=` / `?secret=` +leakage). See `src/lib/api-handler.ts:406`. + +**GLP-1** — Glucagon-like peptide-1 receptor agonist drug class +(Mounjaro/Zepbound/Trulicity = tirzepatide and dulaglutide; +Ozempic/Wegovy/Rybelsus = semaglutide; Saxenda = liraglutide). +Specialist surfaces gated on `Medication.treatmentClass = GLP1`. +See `04-data-model.md` §2.8, `glp1-knowledge.ts`. + +**GROUND RULE** — Numbered clause in the Coach + Insights system +prompts. v1.4.25 ships 15 of them; rules 9 (GLP-1 dose refusal) and +15 (drug-level refusal) are the safety-critical pair. See +`08-locked-contracts.md` §1. + +--- + +## H + +**Health Score** — Composite 0-100 wellness number on the dashboard. +Provenance is surface-side (web) — iOS displays it via the same API +endpoint. Distinct from the Withings "Vascular Age" measure +(`MeasurementType.VASCULAR_AGE`, type 155). + +**hl_onboarding** — Non-httpOnly cookie carrying `"pending"` while +`User.onboardingCompletedAt IS NULL`. Proxy reads it to short-circuit +the post-hydration redirect. iOS does not set this cookie. + +**healthlog_session** — httpOnly session cookie (web). 30-day sliding +expiry. SameSite=Lax so Withings OAuth callback works. iOS uses +Bearer tokens instead; does not set this cookie. + +--- + +## I + +**Idempotency-Key** — Header on every state-changing iOS request. +UUIDv4 string, persisted by the client until a terminal response +arrives. 24h TTL, dedup tuple `(userId, key, method, path)`. See +`17-error-handling.md` §3. + +**Insight** — Long-form chart-anchored analysis on the Insights +surface (e.g. /insights/blutdruck). Generated server-side by the +provider chain; cached on `User.insightsCachedText` until a fresh +generation evicts. Distinct from **Briefing** + **Coach**. + +--- + +## M + +**Maintainership Banner** — UI badge on `/coach` (FR/ES/IT/PL only) +flagging that the locale's Coach prompt body is AI-drafted with +ongoing human review. Links to a GitHub issue template for reporting +refusal regressions. EN + DE prompts are hand-curated; no banner. + +**MDR** — EU Medical Device Regulation (EU) 2017/745. HealthLog is +engineered to stay below the Class I "predict / advise" threshold — +no plasma concentration values, no clinical claims, no dose +recommendations. Cited verbatim in GROUND RULE 15 (drug-level +refusal). See `glp1-pk.ts:1-65` for the regulatory rationale. + +**MDCG 2021-24** — Medical Device Coordination Group guidance +document on Class I borderline products. Co-cited with MDR by GROUND +RULE 15. The HealthLog Coach explicitly references both when +refusing drug-level questions. + +**Measurement** — Single time-stamped reading row. The most-written +table in the schema. Five-axis unique key +`(userId, type, measuredAt, source, sleepStage)` plus a separate +batch dedup key `(userId, type, source, externalId)`. See +`04-data-model.md` §4.1. + +--- + +## O + +**OneCompartment PK** — One-compartment pharmacokinetic model +implemented in `src/lib/medications/glp1-pk.ts`. First-order +absorption + first-order elimination. Sufficient for the qualitative +phase chip ("rising / peak / fading") and the unit-less research-mode +AreaChart. **Two-compartment is explicitly out of scope** — it +crosses the MDR predict/advise threshold. See `glp1-pk.ts:1-65`. + +**OpenAPI hard-flip** — As of v1.4.25, `pnpm openapi:check` HARD-FAILS +CI on drift between the Zod registry (`src/lib/openapi/registry.ts`) +and `docs/api/openapi.yaml`. Was `continue-on-error: true` through +v1.4.23. iOS Swift codegen reads the committed YAML. See +`08-locked-contracts.md` §3. + +--- + +## P + +**Personal Record (PR)** — Best-ever value for a metric (`MAX` +direction: steps, VO2 max, HRV, distance, daylight; `MIN` direction: +resting HR, body fat, audio exposure). Stored on `PersonalRecord` +rows with `direction` denormalised so the read query is one indexed +pass. Detection enqueued automatically on every batch ingest. See +`04-data-model.md` §4.1, Migration 0054. + +**pg-boss** — Postgres-backed background-job queue. HealthLog runs +reminder dispatch, withings sync, host-metric sampling, PR detection, +inventory expire, audit-log cleanup, idempotency-key cleanup, and +the daily feedback aggregator on it. Failed jobs land in +`pgboss.job` with `state = 'failed'`. See `17-error-handling.md` §5. + +**PROMPT_VERSION** — `"4.25.0"`. Constant in +`src/lib/ai/prompts/insight-generator.ts`. Stamped on AI replies for +quality slicing. See `08-locked-contracts.md` §9.2. + +**Push subscription** — Web-push subscription (`PushSubscription` +model, encrypted `p256dh` + `auth`). Distinct from `Device` (APNs). +iOS does not use this — that's web-browser push. + +--- + +## R + +**Range-bar** — Dashboard tile compact chart showing a single +metric's last-N-days as a horizontal bar with the target zone shaded. +Replaces the legacy multi-line spark for v1.4.25. iOS reproduces +this from raw measurement data. + +**Refusal-probe matrix** — `src/lib/ai/prompts/safety-contracts.{en,de,fr,es,it,pl}.yaml` +plus the test driver +`src/lib/ai/prompts/__tests__/refusal-probe.test.ts`. Drives 14 +contracts × 6 locales × 20+ adversarial paraphrasings = >1680 +assertions. iOS must not break the refusals (CI-enforced server- +side). See `08-locked-contracts.md` §7. + +**Research Mode** — Per-user opt-in flag (`User.researchModeEnabled`) +gating the GLP-1 PK research-view chart. Unlocked only after the user +acknowledges the MDR disclaimer at the current version (see below). +The Coach refuses every drug-level question regardless of Research +Mode state (GROUND RULE 15 is universal). See Migration 0058. + +**RESEARCH_MODE_DISCLAIMER_VERSION** — Constant `"2026-05-14.1"` in +`src/lib/medications/glp1-pk.ts`. Format `YYYY-MM-DD.N`. Compared +byte-wise against `User.researchModeAcknowledgedVersion`. Drift forces +re-acknowledgment. See `08-locked-contracts.md` §6. + +--- + +## S + +**Sentinel observation** — Pattern of consecutive measurements that +crosses a user's threshold for the first time in the trailing +window. Insights surface flags it as `severity: "important"`. iOS +displays the flag verbatim. + +**Source-priority two-axis** — Per-user `User.sourcePriorityJson` +controlling cross-source dedup. Axis 1 = metric × source ladder; +axis 2 = metric × device-type ladder. iOS Settings → Sources surface +edits both. See Migration 0051 + W8c, `08-locked-contracts.md` §4. + +--- + +## T + +**treatmentClass** — `Medication.treatmentClass`. Enum +`MedicationCategory` (`GENERIC | GLP1`). Gates the GLP-1 surfaces +(injection picker, titration, pen inventory, side-effects, GLP-1- +aware Coach). Distinct from the clinical-taxonomy side-table +(BLOOD_PRESSURE, VITAMIN, …). See `04-data-model.md` §2.8. + +--- + +## U + +**useInsightStatus** — React hook (`src/hooks/use-insight-status.ts`) +the web surface uses to poll an Insights category's generation +status. Not used on iOS — iOS hits the insights endpoint directly +and renders the response. + +--- + +## W + +**Wide Event** — HealthLog's primary log line shape (one event per +request, structured). Built by `WideEventBuilder` +(`src/lib/logging/event-builder.ts`). Carries `http.method`, +`http.path`, `http.status`, `auth.user_id`, `auth.auth_method`, +optional `error`, optional `action.name`, optional `meta`. iOS does +not produce these directly — the server logs each incoming request. + +**Withings** — Smart-scale + watch + BP-cuff vendor. HealthLog +syncs via OAuth-3-leg + push webhook. iOS reads Withings data +through the same protected measurement endpoints (no separate +Withings flow on iOS). See `05-auth-flows.md` §4. + +**Workout** — `HKWorkout`-aligned typed entity. v1.4.25 ships the +ingest endpoint + 1:1 nested `WorkoutRoute` (GeoJSON LineString). +See `04-data-model.md` §4.2, Migration 0053. + +--- + +## Cross-reference table — where each concept is canonical + +| Term | Canonical doc-pack file | Canonical code file | +| --- | --- | --- | +| GROUND RULES 1-15 | `08-locked-contracts.md` §1 | `src/lib/ai/prompts/safety-contracts.ts` | +| Refusal-probe matrix | `08-locked-contracts.md` §7 | `src/lib/ai/prompts/safety-contracts.*.yaml` | +| Coach-Snapshot | `12-ai-coach.md` (Agent D) | `src/lib/ai/coach/snapshot.ts` | +| Measurement model | `04-data-model.md` §4.1 | `prisma/schema.prisma:363` | +| Source-priority two-axis | `08-locked-contracts.md` §4 | `src/lib/validations/source-priority.ts` | +| Bearer + refresh flow | `05-auth-flows.md` §3 | `src/lib/auth/refresh-token.ts` | +| Idempotency-Key contract | `17-error-handling.md` §3 | `src/lib/idempotency.ts` | +| Rate-limit (Postgres-anchored) | `17-error-handling.md` §4 | `src/lib/rate-limit.ts` | +| RESEARCH_MODE_DISCLAIMER_VERSION | `08-locked-contracts.md` §6 | `src/lib/medications/glp1-pk.ts:92` | +| PROMPT_VERSION (4.25.0) | `08-locked-contracts.md` §9.2 | `src/lib/ai/prompts/insight-generator.ts:34` | +| Withings webhook path-segment | `08-locked-contracts.md` §8 | `src/app/api/withings/webhook/[token]/route.ts` | +| OneCompartment PK scope-limit | `20-glossary.md` (this file) | `src/lib/medications/glp1-pk.ts:1-65` | + +--- + +## What is NOT in this file + +- **Architecture overview** → `02-architecture.md` (Agent A) +- **UI primitives, design tokens** → `09-ui-state.md` (Agent C) +- **AI provider chain, model selection** → `12-ai-coach.md` (Agent D)
