+### Status block — Phase E2 (deploy + verify)
+
+- 2026-05-10T03:48+02:00 — Phase E2 complete; v1.4.16 LIVE at
+  https://healthlog.bombeck.io.
+  - **GHCR**: BOTH runs `success` — Wave-C C3 fix (drop arm64 from
+    main-branch publish) was effective. Run `25616783583` (tag) +
+    `25616782255` (main) both green.
+  - **Image digest**: `ace7d441f47b…` (v1.4.15) → `05f8a126d639…`
+    (v1.4.16). Visibly changed.
+  - **/api/version transition**: `1.4.15` → `1.4.16` at
+    `2026-05-10T03:45:58+02:00` (1 s after host-side retag returned;
+    well under 5 min cap).
+  - **Coolify auto-deploy**: NO — same race as v1.4.14/v1.4.15.
+    Coolify fired on chore(release) commit at `01:40:17Z` BEFORE
+    GHCR finished, so pulled stale local `:latest`. Ran
+    retag-on-host fallback (`docker pull :1.4.16 && docker tag
+    :1.4.16 :latest && docker compose up -d app`).
+  - **Smoke (14 routes, Marc's session)**: 13/14 200; `/dashboard`
+    404 expected (root `/` is the dashboard, no `/dashboard` route
+    exists — same response shape on v1.4.15, NOT a regression).
+  - **GH release**: https://github.com/MBombeck/HealthLog/releases/tag/v1.4.16
+    (created via `gh release create v1.4.16`, notes from
+    `sed -n '3,171p' CHANGELOG.md`; awk recipe in the phase-E2 brief
+    had a precedence issue and only captured the version header — sed
+    range-extract used instead).
+  - **Outstanding for v1.5**: Coolify auto-deploy race (Marc-side UI
+    flip per `docs/audit/v1416-auto-deploy-fix.md`); arm64 reinstatement
+    via native `ubuntu-24.04-arm` matrix (currently amd64-only post-C3).
+  - Detailed report: `.planning/phase-E2-report.md`.
+
+### Status block — Phase E1 (verify + tag)
+
+- 2026-05-10T03:40+02:00 — Phase E1 complete on origin/main.
+  - Verification: `pnpm typecheck` 0 errors, `pnpm lint` 0 errors / 12
+    pre-existing warnings, `pnpm test` 1540/1540 (192 files, 4.29s),
+    `pnpm test:integration` 59/59 (16 files, 8.35s). `pnpm format:check`
+    skipped per project convention (not in CI; `pnpm format` corrupts
+    `.planning/` markdown list-markers — already observed in Phase 0).
+    `pnpm build` + `pnpm e2e` deferred to CI Docker (Node 22).
+  - Release commit: `d443c22 chore(release): v1.4.16` (package.json
+    1.4.15→1.4.16 + CHANGELOG entry, English-only per Marc's "alles
+    Englisch" note).
+  - Tag pushed: `v1.4.16` (annotated, message `HealthLog v1.4.16`).
+  - Push: `5e89382..d443c22 main -> main` + `[new tag] v1.4.16` to
+    `github.com:MBombeck/HealthLog.git`.
+  - GHCR run: id `25616783583` (Build & Publish Docker Image on

+# HealthLog v1.4.16 — Release Summary
+
+## Marc-Brief
+
+✅ Live: v1.4.16 on `https://healthlog.bombeck.io` — image digest
+`sha256:05f8a126d639…` (was v1.4.15: `ace7d441f47b…`), `/api/version`
+returns `1.4.16`.
+
+🆕 **What's new**
+
+- AI insights now show **WHY** each recommendation appears — data
+  window, comparison, deviation — with a confidence meter and a
+  thumbs feedback control on every rec.
+- Medical citations on relevant recommendations (AHA / ESH / ESC /
+  WHO / DGE), opening the source guideline in a new tab.
+- Multi-provider AI fallback chain configurable in Settings → AI
+  (Codex / OpenAI direct / Anthropic / Local / Admin OpenAI).
+- Apple-Health-style chart polish: gradients, rich tooltips, in-target
+  shading, 90-day median personal baseline, mood emoji glyphs.
+- Comparison overlay on charts, tiles, and the AI summary: "vs. last
+  month" / "vs. last year" with delta callout.
+- New Settings → Export consolidates doctor-report PDF + measurements
+  / medications / mood CSV + full JSON backup in one page.
+- Achievements page (`/achievements`) plus dashboard preview card.
+- Onboarding tour for new users (skippable, replayable).
+- Admin host-load chart, app-log preview with JSON inspector, and
+  AI-quality dashboard.
+- Backup full lifecycle — restore, download, upload, audit trail.
+
+🔧 **What's fixed**
+
+- BD-Zielbereich percentage finally counts in-range readings (predicate
+  was too narrow — was always 0% on normotensive data).
+- Trend on "all" filter shows a meaningful split-half delta instead of 0.
+- Top-tile selector actually filters now (widget enum bug; layout PUT
+  silently 422'd).
+- Login overview no longer strips umlauts ("Nürnberg", "München",
+  "Düsseldorf", "Köln").
+- `/admin/api-tokens` table is responsive on mobile (card list at <md).
+- Skip-link no longer blocks logo click.
+- Cached AI insights replaced when regenerated (no stale dashboard).
+
+⚙️ **Infrastructure**
+
+- `docker-publish` main-branch hang fixed — root cause was qemu-arm64
+  SIGILL during multi-arch emulation; arm64 dropped from main publish.
+  Native ARM runner matrix planned for v1.5.
+- CI integration tests + e2e workflows green again.
+
+⚠️ **Hard-Reload** (`Cmd+Shift+R`) for SW reset.
+📚 **Docs site updated** — three new deep-dive pages: AI Insights —
+How It Works, Comparison Views, Provider Configuration.
+🎯 **v1.5 roadmap**: see `.planning/phase-D-product-lead-review.md`.

+## What was deferred + why
+
+Full backlog: `.planning/v15-backlog.md`. Highlights:
+
+- **11 HIGH from QA → v1.5 backlog**: H3 strict B5b/B5c/B5d wiring
+  into `/api/insights/generate`, H4 `findRecommendationsMissingRationale()`
+  is a no-op on parsed payload, H7 comparison overlay single-period
+  audit, H8 ai-section seedKey race-window, design H5 hero gradient
+  bump, design H8 DE fallback-chain row overflow, senior-dev H1 (`src/lib/ai/`
+  19 flat files re-shape), senior-dev H2 (`<InsightAdvisorCard>` 690 LOC
+  god-component split), senior-dev H3 (`<RecommendationCard>` 417 LOC
+  split), code-review H5 + H6 cumulative duplication. Sized in the
+  product-lead review.
+- **2 simplify-no items**: F1 `runWithFallback` test-only (delete and
+  migrate or wire to strict variant — Marc's call), F8
+  `RecommendationCard.normalise()` indirection (mechanical rewrite
+  spans 8+ JSX sites).
+- **Native ARM runner matrix** for `docker-publish` — qemu-arm64
+  SIGILL forced amd64-only on main; native `ubuntu-24.04-arm` matrix
+  is the v1.5 plan.
+- **Coolify image-digest auto-deploy** — still on git-push trigger;
+  deferred per Marc's "leave it" call. Marc-side UI flip is the 5-min
+  realistic fix per `docs/audit/v1416-auto-deploy-fix.md`.
+- **Cross-user feedback aggregation prompt-tuning ratchet** — B5e
+  set up the storage and the daily aggregator; the prompt-mutation
+  loop itself is v1.4.17 / v1.5 work.
+- **Dedicated `/insights/compare` page** — B8 deferred this; the
+  overlay-on-charts ships in v1.4.16. i18n keys
+  `comparison.insightsCallout.{lastMonth,lastYear}` reserved so the
+  future component drops in clean.
+- **Senior-dev H1 + H2 splits from v1.4.15** — both still open;
+  carry forward into v1.4.17 architectural pass.
+- **Mood-chart H3 (chart-presentation) from v1.4.15** — chart-
+  ownership rule keeps this with charts owners; pick up next time
+  a chart-presentation pass runs.
+
+---
+
+## CI / Test status
+
+- `pnpm typecheck` — 0 errors.
+- `pnpm lint` — 0 errors / 12 pre-existing warnings.
+- `pnpm test` — **1539 unit tests** green (started v1.4.16 marathon
+  at ~1048; +491 net across A/B/C/D/E waves).
+- `pnpm test:integration` — **59 / 59** green (was 31 at v1.4.15).
+- `pnpm format:check` — not in CI; new files prettier-formatted via
+  `c63cddc` style sweep.
+- `pnpm build` + `pnpm e2e` — deferred to CI Docker (Node 22) per
+  project convention; CI runs green.
+
+---
+
+## Production state
+
+- **URL**: `https://healthlog.bombeck.io`
+- **`/api/version`**: `1.4.16` ✓
+- **Image digest**:
+  `sha256:05f8a126d63962d9a4af4769de830d3fee022d634787e811b4339ee464420daa`
+  (was v1.4.15: `sha256:ace7d441f47bd8c69fd0c5e2417b7f6c53bc387aa10c9aa541ad5e6321e9581d`)
+- **Smoke** (14 routes, Marc's session): 200 across `/`, `/insights`,
+  `/auth/login`, `/settings/integrations`, `/settings/notifications`,
+  `/settings/ai`, `/settings/export`, `/admin`, `/admin/users`,
+  `/admin/backups`, `/admin/system-status`, `/admin/app-logs`,
+  `/achievements`. `/dashboard` 404 expected — HealthLog's dashboard
+  lives at `/` (PWA convention), there is no `/dashboard` route in
+  the App Router tree (NOT a regression — same shape on v1.4.15).
+- **Deploy method**: GHCR-tag-build `:1.4.16` succeeded (Wave-C C3
+  fix dropped arm64 on main and made BOTH GHCR runs green for the
+  first time since v1.4.13). Coolify auto-deploy fired on the
+  `chore(release)` commit before GHCR finished and pulled the host's
+  stale local `:latest` cache; retag-on-host fallback (`docker pull
+  :1.4.16 && docker tag :1.4.16 :latest && docker compose up -d app`)
+  flipped `/api/version` 1 s after the up command returned.
+- **Coolify auto-deploy**: still fires on every git-push (deferred
+  per Marc's call); v1.5 plan in `docs/audit/v1416-auto-deploy-fix.md`.
+- **GitHub release**: https://github.com/MBombeck/HealthLog/releases/tag/v1.4.16
+- **Tag naming** (unchanged since v1.4.14): GHCR-OCI tag is `:1.4.16`
+  (no `v` prefix); git tag is `v1.4.16`.
+
+---
+
+## Docs / Landing
+
+- **healthlog-docs** (Starlight) — 44 pages, three new deep-dive
+  routes:
+  - `/insights/how-it-works/` — recommendation card walk-through,
+    deterministic confidence computation, fallback hard-fail policy,
+    "low confidence" semantics, feedback usage today + planned,
+    per-user privacy.
+  - `/dashboard/comparison/` — toggle UX, forward-shift overlay
+    semantics, what vs.-last-month / vs.-last-year actually compute,
+    sparse-data handling, deferred follow-ups.
+  - `/settings/ai-providers/` — setup paths for all five providers,
+    fallback-chain editor, test-connection, credential storage table.
+- **healthlog-landing** (Next.js) — `softwareVersion 1.4.15 →
+  1.4.16` in JSON-LD; AI-insights hero card rewritten as "AI insights
+  that show their work" leading with explainability + confidence +
+  citations; capability badges row picks up two new badges.

+
+## v1.5 strategic outlook
+
+The Product-Lead review at `.planning/phase-D-product-lead-review.md`
+contains the full v1.5 roadmap and is the strategic plan for v1.5.
+Top items to look at:
+
+1. **Coolify image-digest trigger** (C.1) — replaces git-push churn.
+   5-min Marc-side UI toggle.
+2. **Native ARM runner matrix** (C.2) — re-add `linux/arm64` to
+   GHCR matrix via native `ubuntu-24.04-arm` runner.
+3. **Cross-user feedback ratchet → prompt-tuning** (C.3) — append
+   per-(severity × confidence_band) "OMIT" / "REPHRASE" rules to
+   PROMPT_VERSION when a bucket's helpful-rate drops below threshold.
+4. **Dedicated `/insights/compare` page** (C.4) — sticky baseline
+   picker + `aiInsightResponseSchema.comparison` field +
+   `<InsightsComparisonCallout>` above the recs grid.
+5. **iOS native client API contract freeze** (C.7) — versioned
+   `/api/v1/` router, `POST /api/measurements/bulk` for offline-queue
+   replay, document the 24h access / 90d refresh defaults so iOS
+   doesn't surprise-fail at 24h+ε.
+6. **Apple Health import via iOS** (C.11a) — XML parse + map +
+   bulk endpoint; the natural pipe is the iOS app.
+7. (See review §C.5 streaming + A/B + per-user prompt prefix, §C.6
+   charts library decision, §C.8 security hardening sweep, §C.9
+   performance, §C.10 S3 backup push, §C.11 Garmin / Oura
+   integrations.)
+
+Marc's recommended 6-week focus pick from the review: **C.1 + C.2 +
+C.4 + C.7 + C.10 + C.11a Apple Health**.

+
+## Hard-Reload reminder
+
+`Cmd+Shift+R` (Mac) / `Ctrl+Shift+R` (Linux/Win) — the new service
+worker otherwise still serves v1.4.15 chunks from cache. One-shot is
+enough.
