 ## [Unreleased]
 
 ### Added
+- **Gigs (the career verb, frontend)** — book a gig from any opened passport:
+  a gig poster proposes the setlist (re-roll for a different bill; save or
+  copy the poster as a PNG), "Play the gig" hands the set to the play queue
+  with the venue on stage, a floating strip tracks the set, and finishing it
+  logs dated entries with per-song accuracies in the passport book — with an
+  encore celebration (crowd eruption + confetti) when the whole set clears
+  the bar, and a summary poster to share. Quitting mid-set simply abandons
+  it: no log, no fail state.
+- **Career on the Profile and Home pages** — the Profile gains a passport
+  wall (earned-badge covers per instrument, hours, gig count; absent until a
+  passport exists), injected through the same mount-point + rendered-event
+  seam the achievements plugin uses (now documented in docs/plugin-v3-ui.md).
+  The home page's plugin-count stat tile becomes a career trading card
+  (badges, hours, the closest stamp ask, foil shine) with the old stat as the
+  built-in fallback when career has no state. Earned passports gain **Save
+  card / Copy card** — a natively-drawn PNG passport card, downloadable or
+  copied straight to the clipboard for pasting outside the app (shared
+  `blob-io` helpers replace the download idiom previously duplicated in
+  settings-io and diagnostics-export).
+- **Gigs (backend)** — career mode gains its verb: `POST
+  /api/plugins/career/gigs/propose` builds a playable setlist for an
+  instrument+genre (your qualifying songs plus a couple of stakes songs near
+  the bar; a young passport fills from unplayed genre songs — the first gig
+  is how stubs start; re-roll by calling again), naming the room your stars
+  can book. `POST /gigs` logs a **completed** set — per-song accuracies read
+  from the set's own freshly-recorded stats, an encore flag at the
+  data-driven bar (avg ≥ 75%) — into the career state; abandoned sets never
+  log (no fail state: the gig you finished is the gig you played). Passports
+  carry their gig log; instruments their gig count.
+
+### Changed
+- **The full mix is a stem** (#933) — core no longer depends on `original_audio:`, a
+  top-level manifest key this repo invented (#583) that the feedpak spec never had.
+  The format already carried the pre-separation mixdown as a stem; feedpak 1.15.0
+  (feedpak-spec#53) reserves the id **`full`** for it, so that is where core reads it
+  from now.
+
+  `full` is a mixdown, not a layer — it already contains every instrument — so
+  `load_song()` lifts it OUT of `LoadedSloppak.stems` onto `LoadedSloppak.full_mix`.
+  Nothing that sums stems or renders one fader per stem can see it, which is what
+  makes retaining it safe; leaving it in the list would double the whole song and
+  leave "guitar" audible with the guitar fader muted. That trap is exactly why the
+  packer invented the key instead of putting the mixdown where the format says it
+  goes — the bug was in the reader, and this fixes the reader.
+
+  Consequences worth knowing:
+  - The highway WS `song_info` frame gains `full_mix_url` / `has_full_mix`.
+    `original_audio_url` / `has_original_audio` remain as **deprecated aliases**
+    (same values) for one release so a client built against the old frame keeps
+    working; they go with the fallback below (#945).
+  - `stems` on `song_info`, and `stem_ids` / `stem_count` in the library index, now
+    describe *instrument* stems only — a separated pack that retains its mixdown no
+    longer advertises a bogus "full" stem chip or an inflated stem count.
+  - Audio fingerprinting (`lib/enrichment.py`) now resolves the mixdown the same
+    way, which **widens** its coverage: it previously returned `None` for any pack
+    without the invented key, so fingerprinting silently did nothing for the
+    overwhelming majority of packs.
+  - Core still **reads** `original_audio:` as a deprecated fallback, because every
+    pack written before the spec caught up carries it and would otherwise lose its
+    pristine mix. `tools/migrate_full_mix_stem.py` rewrites those packs into the
+    spec shape (moves `original/full.ogg` → `stems/full.ogg`, adds the `full` stem
+    at `default: off`, drops the key); the fallback and the aliases are removed once
+    they are migrated (#945).
+
+### Added
+- **Genres fall back to MusicBrainz enrichment** — the effective genre now
+  resolves override → pack genre → the enrichment match's primary genre
+  (matched or user-pinned manual rows only). Converted packs rarely carry a `genres` manifest key,
+  which starved the library genre facet and career passports on real
+  libraries; with the fallback, every enriched song's genre is browsable and
+  passport-able immediately, and coverage grows as enrichment runs.
 - **Badge ceremony in the venue** — earning a genre badge now stages a moment:
   the crowd layer erupts (new public `v3VenueCrowd.celebrate()` — instant
   ecstatic loop bypassing the stability/dwell hysteresis, plus a cheer stinger;

+## Injecting into core shells (profile, dashboard)

+Core screens that accept plugin sections render **mount points** — usually
+empty, sometimes holding core's own **fallback content** (the Dashboard's

+DOM event, because their `innerHTML` swap wipes anything previously injected.

+| Settings | `v3:settings-rendered` | per-plugin `settings.html` panels |

+Rules: inject on every event (the mount is fresh), keep the section

+  - it never evicts the song the caller just asked for,
+  - an evicted song is dropped from _source_cache too (otherwise the media route
+    keeps serving a path that no longer exists and 404s every stem instead of
+    re-unpacking),
+  - get_cached_source_dir() self-heals if the cache dir is deleted by hand,
+  - read_member_bytes() reads one file WITHOUT unpacking anything.

+#!/usr/bin/env python3
+"""Migrate packs off the deprecated `original_audio:` key — the full mix is a stem.
+
+Before feedpak 1.15.0 reserved the stem id `full`, spec §5.3 said the mixdown was
+"commonly replaced" by the per-instrument stems when a pack was split — so after
+separation it had nowhere to live. This repo worked around that by inventing a
+top-level `original_audio:` manifest key pointing at a parallel `original/`
+directory (#583). The key was never in the spec, and #933 removed core's
+dependence on it: the mixdown is a stem, and its id is `full`.
+
+This rewrites a pack into the shape the spec now defines:
+
+    original/full.ogg                  ->  stems/full.ogg          (entry moved)
+    original_audio: original/full.ogg  ->  stems: [{id: full, file: stems/full.ogg,
+                                                    default: 'off'}, ...]
+
+`default: 'off'` is what makes the retained mixdown safe: a reader that honours
+`default` (normative since feedpak 1.0.0) will not play it on open, so it never
+doubles the mix even in a reader that predates the reserved id.
+
+Nothing else in the pack is touched — every other key, file and stem is preserved
+verbatim, and `feedpak_version` is stamped to the version the result conforms to.
+
+The rewrite is atomic per pack: a new archive is built beside the original and
+renamed over it only on success, so an interrupted run leaves every pack either
+fully migrated or untouched — never truncated.
+
+Idempotent: a pack that already carries a `full` stem and no `original_audio:` is
+reported as `skip` and left alone, so a partial run can simply be re-run.
+
+Usage:
+    python tools/migrate_full_mix_stem.py --dry-run /path/to/packs   # report only
+    python tools/migrate_full_mix_stem.py /path/to/packs             # migrate
+    python tools/migrate_full_mix_stem.py --verify /path/to/packs    # check results
+
+Exit status is 0 only when every pack ended up in the migrated shape (or was
+already there).
