Document read-only on-box verification via start-cli

Record the installed-version / package logs / attach+sqlite3 commands used to
verify ALTERs and persisted data on the box, so future sessions verify
directly instead of deferring to the StartOS web UI.

+**Verify on-box state read-only via `start-cli`** (the same host config) instead of punting to the StartOS web UI — used this way to confirm the 1.2.0:4/:5 ALTERs and a persisted set:
+- `start-cli package installed-version proof-of-work` — what version the box actually runs.
+- `start-cli package logs proof-of-work --limit N | grep -iE "adding missing column|as nextjs|error"` — confirms boot ALTERs ran (each logs once) and the non-root launch.
+- `start-cli package attach proof-of-work -- sqlite3 /data/app.db "<SELECT …>"` — read-only query of the live app DB (e.g. confirm a new column exists / a value persisted). **SELECT only**; never mutate prod data this way.

 `npm run db:seed` (= `tsx prisma/seed.ts`) seeds **only the `InstanceSettings` singleton** — deliberately NO users and NO curated library (the library attaches at admin-creation and via the boot-time ensure). It is **live, not dead** — invoked at Docker image-build time (`start9/0.4/Dockerfile`) and the local-dev first-run path. `npm run create-admin` (= `tsx scripts/create-admin.ts`) is the local-dev equivalent of the StartOS "Set admin credentials" action: creates the first admin + seeds their library; `--force` to reset/promote an existing account. Runtime first-boot/upgrade seeding is handled separately by `docker_entrypoint.sh`.

 - **Bump the version BEFORE building the s9pk** — Start9 0.4 won't recognize a rebuild as an update otherwise.
 - **Schema changes are additive ALTERs in `docker_entrypoint.sh`**, guarded by `PRAGMA table_info` checks. Keep `schema.prisma` in sync as the mirror, but the entrypoint is what migrates live `/data`. Never write a destructive migration.
 - **Adding a first-class numeric set metric** (precedent: `watts`, 1.2.0:4): mirror `calories` end-to-end — `schema.prisma` column + `prisma generate`; guarded additive `ALTER` in `docker_entrypoint.sh`; zod field + insert in all **5 set-write paths** (`workouts` POST, `workouts/[id]` PATCH, `workouts/[id]/sets`, `workouts/import/save`, `me/import`); `SetRow.tsx` (`show*`/state/`emitUpdate`/`buildSummary`/`firstField`/input) + `WorkoutForm.tsx` (set interfaces, `buildPayload`, `handleUpdateSet`, `initial*` prop, has-data checks); read summary in `app/main/workouts/[id]/page.tsx` + edit mapping in `app/main/workouts/new/page.tsx`; CSV export/parse + `page-csv` payload; field-option label lists (`lib/exerciseOptions.ts`, `app/main/exercises/[id]/page.tsx`, `ExercisePicker.tsx`). The `inputFields` token == the column name; the human label lives in those option lists (token `watts` → "Avg. watts"). `me/export` rides the 1:1 Prisma dump automatically. Add a round-trip test in `tests/routes-crud.test.ts`.
+- **Logged-set effort is Gear or RPE, by cardio-ness** (1.2.0:5): the effort select is always shown (not an `inputFields` token). Cardio exercises log breathing **Gear** (`SetLog.gear`, 1–5); everything else logs **RPE** (`SetLog.rpe`, 6–10). The switch is `isCardioExercise(exercise)` (`lib/exerciseOptions.ts`): `type === "cardio"` OR `muscleGroups` contains "cardio". `SetRow` takes an `isCardio` prop (from `WorkoutForm`) and renders one; both are always emitted (the hidden one stays empty). Distinct from program/AI **target**-RPE (`ProgramExercise.rpe`), which is unrelated and unaffected.
 - **Commit subject** = `vX.Y.Z:N — short summary`, imperative, body explains the *why*.
 - **Git remote is self-hosted** (a private Start9 registry + a FileBrowser artifact host), NOT GitHub. The actual registry/file-host URLs are constants in `~/.proof-of-work/{publish,unpublish}.sh`; FileBrowser creds live in `~/.keysat/filebrowser.env` (outside the repo, gitignored). Default branch is `master`.
 - **Authorization tiers**: whole-instance routes (`settings/{export,import}-db`) are **admin-only** (`!user.isAdmin → 403`); per-user data routes scope by `user.id`. Custom-URL AI providers (Ollama, OpenAI-compatible — anything with `requiresBaseUrl`) are **admin-only** (SSRF surface); fixed-URL cloud providers (claude/openai/gemini) stay per-user. Gate the server route AND hide the control in the UI.

 ## Current state
 
-Latest version is **1.2.0:4** — **avg. watts is now a first-class set field**: promotes average watts (assault bike / rower / ski erg) from a free-text `customMetrics` JSON entry to a real nullable `SetLog.watts` column, written through every set path (create / PATCH / add-sets / import-save / account-import) and shown everywhere as "Avg. watts" with a numeric input. This is the **first schema change in the 1.2.0 line**: the column is added by the boot-time additive `ALTER` in `docker_entrypoint.sh` (guarded, idempotent); legacy watts in `customMetrics` stays readable and migrates to the column on next save (no data migration). Internal token/column is `watts` (matches the existing assault-bike `inputFields` token + legacy `customMetrics` key → zero exercise migration); only ever *displayed* as "Avg. watts". **Built + sideloaded** to the StartOS box (`immense-voyage.local`, 2026-06-16, on `master`) as `proof-of-work_x86_64.s9pk` (80M, git `390aaf5`). Verified before build: tsc clean (app + packaging), lint clean (only pre-existing warnings), **223 tests pass**, `next build` succeeds. Registry empty, **publishing parked** (sideload-only via `make install`).
+Latest version is **1.2.0:5** — **Gear replaces RPE as the cardio effort field**: cardio exercises now log a breathing "Gear" (1–5, Brian MacKenzie) select instead of RPE (6–10); strength keeps RPE. An exercise is cardio when its equipment `type` is "cardio" **or** its `muscleGroups` contains "cardio" (`isCardioExercise` in `lib/exerciseOptions.ts`) — so Assault Bike (type "assault bike") qualifies, as do Box jump & Soccer (both tagged cardio). New nullable `SetLog.gear` column via boot-time guarded `ALTER`; plumbed through all 5 set-write paths, summary/edit views, CSV/JSON import-export. Program/AI **target**-RPE is a separate concept and untouched. **Built + sideloaded** (`immense-voyage.local`, 2026-06-16, `master`) as `proof-of-work_x86_64.s9pk` (80M, git `4be489d`).

-Recent prior ships (1.2.0 line): **1.2.0:3** — P3 hardening (login timing oracle + `exerciseId` ownership). **1.2.0:2** — iOS Safari login/signup first-tap retry (`lib/retryAction.ts`). **1.2.0:1** — Next 15 / React 19 upgrade. (1.2.0:1–3 had no schema/data change.)
+**Confirmed on-box (2026-06-16, via `start-cli`):** box runs `1.2.0:5`; entrypoint logged `adding missing column SetLog.gear` and (earlier boot) `SetLog.watts`, each once; app launches `as nextjs` with no permission errors (clears the 1.2.0:3 / long-standing 1.1.0:9 non-root check). App DB shows an Assault Bike set saved with `gear=1` and no `rpe` — Gear select renders + persists for cardio, RPE for strength. Recent prior ships (1.2.0 line): **1.2.0:3** P3 hardening (login timing oracle + `exerciseId` ownership); **1.2.0:2** iOS Safari login first-tap retry; **1.2.0:1** Next 15 / React 19 upgrade.
 
-**Pending on-box check:** confirm 1.2.0:4 boots clean in StartOS → Logs — on the existing-data upgrade path the entrypoint logs `adding missing column SetLog.watts` (one-shot; no-op thereafter), no permission errors — and that logging an Assault Bike set with Avg. watts saves and displays as `157 W`. Still also pending from earlier ships: the 1.2.0:3 non-root boot (entrypoint logs `launching … as nextjs`, app writes `/data` as uid 1001 — also clears the long-standing 1.1.0:9 non-root check), **and** the 1.2.0:2 Safari first-tap proof (log in from Safari on iPhone/iPad; first Sign In tap works — `-1005` in Web Inspector confirms the retry path, anything else points at a proxy↔container keep-alive mismatch).
+**No on-box checks pending.** Known bug (tracked in `ROADMAP.md` → Known bugs): the **1.2.0:2** Safari first-tap retry did NOT fix the mobile-Safari first-login failure — reproduced on 1.2.0:5, first tap shows "An unexpected error occurred", second tap works. Diagnosis captured; the fix is gated on one data point — the first failed request's error code from Safari Web Inspector (`-1005` → client delayed-retry; `502`/`503` → Node keep-alive tuning).

+- **Mobile-Safari first-login-tap fails ("An unexpected error occurred"); second tap works.** Reproduced on iPhone/iPad Safari against 1.2.0:5 (desktop Safari untested — user declined). The first Sign In tap fails, a second manual tap succeeds. **1.2.0:2's `retryOnTransportError` does NOT fix it.** Diagnosis so far: `LoginForm` only surfaces that error when *both* the initial action call and its in-tap retry throw, so the immediate retry isn't escaping the bad connection — only a fresh user-initiated tap does. Box app logs show no server-side error/500/reset around the attempt, so it's a transport-layer failure, not an app bug.
+  - **Gating data (do this first):** capture the first failed request's error in Safari Web Inspector (iOS→Mac, Network/Console tab). The code picks the fix:
+    - `-1005` "The network connection was lost" → client-side stale keep-alive socket. Fix = a *delayed* retry (let Safari tear down the dead socket before retrying), not the current instant one.
+    - `502`/`503` → StartOS-proxy↔Node keep-alive mismatch (Node closing idle conns the proxy reuses). Fix = raise Node `keepAliveTimeout`/`headersTimeout` server-side; a client retry only masks it.
