Sharing earned Feats on the (forthcoming) public wall is strictly opt-in,
default OFF, with a binding data-minimization contract.
- Onboarding (static/v3/profile.js): a new opt-in step (now a 5-step wizard)
after song-directory / before paths — publishes only display name + earned
Feats, never songs/skills/scores; off by default.
- Settings (plugins/achievements/settings.html, System tab via
settings.category): the same toggle + a "Remove me from the wall" button
(POST remove-me — wipes local synced state offline + enqueues removal).
- Core (server.py): achievements_enabled (bool, default false) in
_default_settings + /api/settings validation + _RESETTABLE_SETTINGS_KEYS;
mirrored to localStorage in app.js loadSettings().
- Data-minimization gate: engine.build_wall_payload is the single explicit-dict
serializer; key-set is EXACTLY {display_name, player_hash, achievement_id,
unlocked_at}, achievement_id always a Feat id. Enqueue is gated on
opted-in AND profile identity (reused player_hash); competency never
enqueues (integration law).
Verified natively: settings round-trip + validation + remove-me; opted-in
activity enqueues exactly one 4-field Feat payload; Playwright confirms the
5-step wizard + opt-in card (default unchecked), zero console errors.
29 plugin tests + new settings tests pass.

Adds the Achievements & Feats of Power local engine, fully offline.
Core (static/v3/profile.js): the Profile screen becomes tabbed exactly
like v3 Settings (.fb-tabbar/.fb-tab/.fb-tabpanel, active tab persisted in
localStorage 'v3-profile-tab'). A Profile (main) tab carries the existing
cards + a Feats trophy-shelf mount (#v3-profile-feats-slot, earned-only),
and an Achievements tab carries a plugin mount
(#v3-profile-achievements-mount) + empty-state note. A new
`v3:profile-rendered` event fires after every render so the plugin
re-injects (mirrors v3:settings-rendered).
New bundled plugin (plugins/achievements/): SQLite engine
(unlocks/counters/comp_ledger/sync_queue) with pure threshold/criterion
math in the testable sibling engine.py (P-V); routes activity/
report-unlock/report-criterion/catalog/earned/feats/remove-me. Feats read
activity counters only (batched song:ended POST; notes only when notedetect
present — graceful degradation); competency Achievements evaluate from
progression events only — the integration law, never crossed. Catalogue is
always shown (locked=greyed), grouped by the real progression paths
(Global/Guitar/Bass/Drums/Keys, auto-extending) with per-category earned
badges. Versioned window.feedBack.achievements registration API with the
__feedBackAchievementsPending load-order queue + achievements:ready event.
Verified natively (uvicorn) end-to-end + Playwright (tabbar, earned-only
Feats shelf, greyed catalogue, registration API, zero console errors);
24 plugin tests pass incl. the integration-law assertion.
Opt-in/privacy/data-min gate (PR2) and the hosted wall (PR3) follow.
