topkoa c485f02211 ci: track the spec's HEAD — the app conforms to the living spec
Design change, at the maintainer's direction: the gate now checks out
feedpak-spec at HEAD instead of a pinned SHA. .feedpak-spec-ref, its
40-char validation step, and the pin-bump machinery are gone.

Rationale: it is vital that the app conforms to the spec — the current
spec, not a snapshot. The pin bought determinism at the cost of a
maintenance loop (bump PRs, a PAT, weekly latency) and a window where the
gate verified against a stale spec. Tracking HEAD makes the dev flow fully
self-serve with zero upkeep: gated PR -> FEP -> spec merge -> re-run
checks -> green. Nothing to bump.

The trade-off is accepted with eyes open, and the docs state it: the
normal FEP is additive and can only loosen the gate, so it cannot redden
anyone's PR. Only a breaking spec change (rare, deliberate, MAJOR per the
spec's compatibility policy) turns PRs red repo-wide — which is the
correct org-wide signal that the app is out of conformance. The CI job
logs the spec SHA each run verified against, so any red run is
reproducible.

Failure messages now also say why it matters beyond the one PR (also at
the maintainer's direction): non-conformance that lands shows up as red CI
on every teammate's PR until it is resolved, and only its author can clear
it — the FEP route keeps everyone else unblocked. Tone softened throughout
(the exceptions-file header now explains rather than shouts).

topkoa 203f82b6fe ci: legible failures for malformed exceptions file; docs catch up
_parse_exceptions() now validates the document shape — top level must be a
mapping, 'exceptions' must be a list, each entry a mapping, and YAML parse
errors are caught — each failing with a ::error:: instead of an
AttributeError traceback. CI output must say what to fix. Parametrised
tests cover all four malformed shapes.

docs/feedpak-spec-gate.md: the Limitations section still described the
pre-flow-aware scanner (KEY_OPS, name-list-only receivers). Now states the
actual residual gaps: function-parameter manifests are recognised by name
only, and helper-mediated literal keys (song.py's
_gap_fill_manifest_absent(manifest, "album")) are unseen by both the scan
and the readers-complete guard, since they share one detector.

topkoa 0158286d06 ci: flow-aware manifest discovery — a name list missed real readers
Review found lib/routers/chart.py binding `m = load_manifest(p) or {}` and
reading eight manifest keys through it. `m` was not in MANIFEST_VARS and
`m.get` did not match the readers-complete regex, so the module was
invisible to BOTH halves of the gate — unlisted and unscanned. Same for
lib/routers/song.py (binds `manifest` from load_manifest for enrichment
gap-fill). Both are now in READERS.

The structural fix, not the name-list patch: keys_touched() now discovers
receivers flow-aware — any local assigned from load_manifest(...) is a
manifest dict, whatever it is called. MANIFEST_VARS remains only as the
fallback for manifests that arrive as function parameters (ws_highway).
A plain `m = {}` is not a receiver; test pins that.

readers-complete now reuses keys_touched() itself instead of a parallel
KEY_OPS regex — the two detectors diverged once already (that is exactly
how chart.py slipped through), so now there is one detector and one truth.

check_reverse() gets a 300s subprocess timeout: the validator executes at a
pinned SHA, but a pathological pack or validator bug should fail the job,
not hang the runner to the Actions-level timeout.

Tests: flow-aware receiver under an arbitrary name (read + write), and the
negative — a plain dict named `m` stays out of the scan. 17 pass.

topkoa 1e2ce29cf6 docs: make FEP-first impossible to miss before the gate fires
The CI gate catches spec drift at merge time; these two additions catch it
at write time, which is where "developer didn't read the spec first"
actually happens.

CLAUDE.md (Song Formats): a spec-is-sacrosanct paragraph next to the spec
pointer — the spec defines the format, the app implements it, any new
manifest key/file/directory lands in the spec first via the FEP process,
and the gate has no in-repo bypass. AI agents and contributors both hit
this while writing feedpak-touching code, not after CI reddens.

.github/pull_request_template.md (new — the repo had only issue templates):
a feedpak-surface section requiring either "doesn't touch pack I/O" or a
link to the landed FEP + the .feedpak-spec-ref bump, plus the standing
changelog/tests/DCO checklist.

topkoa b54b65d35c test: give the spec gate its own regression suite
Self-review finding: the gate is what keeps the app from drifting off the
feedpak spec, but the gate itself had zero pytest coverage — a refactor
could quietly weaken keys_touched or the allowlist logic and nothing would
notice. The protector needs protecting.

tests/test_spec_gate.py pins the load-bearing behaviours:

- read/write classification: get() reads; subscript Store and setdefault()
  write (the two forms that were blind spots in review); the
  load_manifest-wrapped get; unrelated dicts and non-literal keys ignored.
- exceptions file: duplicate keys and issue-less entries rejected.
- the closed allowlist: growth fails, shrink and steady state pass,
  bootstrap skips.
- live-tree checks, same as CI: READERS matches the codebase, and the only
  non-spec key core touches is the grandfathered original_audio.

Also fixes stale "Layer 2/3" docstrings on check_forward/check_reverse
(they are layers 3/4 since allowlist-closed landed) — the same
docs-lag-the-code class this PR's review kept catching; now the numbering
is asserted by the printed [n/4] headers next to them.

topkoa ab2e68a638 ci: resolve the allowlist baseline against the real base branch
The allowlist-closed diff hardcoded `origin main`, but ship-ci.yml also runs
this workflow for PRs into release/** and for pushes to release/**, where a
main baseline diffs against the wrong branch and can fail changes that have
nothing to do with the allowlist. It now resolves the base:

  PR   -> github.event.pull_request.base.ref (the branch it merges into)
  push -> github.ref_name (the branch itself; its tip already contains the
          change, so the diff is a no-op — enforcement happens at PR time)

Also from review, all documentation drift introduced by my own earlier
commits:

- The layer count said "three" in the module docstring, the workflow comment,
  the docs, and the changelog. There are four (allowlist-closed was added).
- The changelog listed three scanned modules; there are five.
- The docs and changelog stated the rule for keys core *reads*, omitting
  writes — which are equally gated, and land in every pack we emit.
- The CI summary line labelled grandfathered keys "pending spec", implying
  adoption is the only resolution. For original_audio it is not: the fix is
  removal. Relabelled "grandfathered (tracked debt)".
- feedpak-spec-exceptions.yml said an entry clears when core "stops reading"
  the key; the rule is "no longer reads or writes".
- Replaced a bitwise `&` over two bools with two named results and an
  explicit `and` — both checks must run (a stale READERS list and an
  undeclared key are separate failures; short-circuiting would hide one), and
  `&` reads like a typo.

topkoa d806d12c22 ci: close two blind spots in the key scan
Review found the gate was scanning less than it claimed.

READERS missed two modules that genuinely touch feedpak manifests:
lib/routers/ws_highway.py (reads `authors`) and lib/gp2notation.py (loads
manifest.yaml, stamps feedpak_version, writes the file back). Keys touched
there were going entirely unchecked.

The scan also only recognised writes done via subscript, so
`manifest.setdefault("k", v)` — exactly how gp2notation.py stamps
feedpak_version — was invisible. setdefault with a literal key now counts as
a write.

The deeper problem is that READERS is hand-maintained, and a hand-maintained
list rots; that is how both modules went unnoticed. check_readers_complete()
now re-derives the set: any module under lib/ (or server.py) that both
touches manifest keys and shows a feedpak signal must be listed, or the build
fails. It is a guard on the gate itself.

The list stays explicit rather than becoming a glob, because `manifest` is
overloaded here: lib/loosefolder.py (the loose-folder manifest.json) and
lib/diagnostics_bundle.py (the diagnostics bundle manifest) have their own
unrelated manifests, and scanning those would flag *their* keys as feedpak
drift. Both score zero on the feedpak signals, which is what keeps them out.

Now scanning 5 modules: 20 reads, 2 writes, all spec-declared.

topkoa 32d723b774 ci: close the escape hatches — the FEP process is the only route
The gate's purpose is to make a non-conforming change *not merge*, so the
person merging must stop and decide whether to take it through the format
process. The escape hatches defeated exactly that: a developer who did not
want to write a FEP could name their key `x-whatever`, or append an entry to
feedpak-spec-exceptions.yml with any issue link, and merge. Both were
self-serve and in-repo. That is a speed bump with a signed excuse note, not a
gate.

The relief valve is the FEP process itself, not something in this repo. The
spec's governance already says so: "A change is not part of the format until
it lands here."

Removed the `x-` prefix bypass. It was invented here, not in the spec — the
spec reserves no experimental namespace. Its "unknown keys are reserved for
forward-compatibility" rule is about *tolerating* other implementations'
keys, not a licence for core to mint its own.

feedpak-spec-exceptions.yml is now a CLOSED grandfather list. A new check
(allowlist-closed) diffs it against the base branch and fails any PR that
ADDS an entry; removal stays allowed, so the list can only shrink. Deleting
an entry does not by itself pass the gate — key-coverage still fails while
core reads the key, so the entry goes when the code goes.

Every failure message now points at the FEP process and at bumping
.feedpak-spec-ref to the merged spec SHA, which is the one supported way a
new manifest key reaches core.

CI fetches the base branch to diff the allowlist; the bootstrap flag covers
the one case with no baseline — the PR introducing the gate.

topkoa ceb1e143cd ci: second review pass — recurse examples, reject duplicate exceptions
Six more findings from CodeRabbit and Copilot on #934. All valid; four were
my own docs lagging the write-checking change in d0626f5.

check_forward() now discovers example packs recursively, so a pack nested
under examples/<group>/ can't slip past the "every example pack" contract.
Taken WITHOUT the suggested is_file() filter, which would have broken it: a
feedpak is dual-form — a zip (foo.feedpak) or a directory (foo.feedpak/) —
and the spec's own examples ship as directories, so is_file() would have
matched zero packs. Suffix matching covers both forms.

load_exceptions() rejects duplicate keys instead of silently keeping the
last one, which would quietly retarget the tracking issue for a piece of
debt this file exists to track.

The sloppak import is wrapped so a missing dependency produces a CI-legible
::error:: rather than a bare traceback.

Docs caught up with the code: the exceptions file header, its stale-entry
rule, and the changelog all said "reads" when the gate checks reads AND
writes.

topkoa d0626f5618 ci: address review — check writes too, pin deps, harden the spec pin
Review feedback from CodeRabbit and Copilot on #934. All six findings were
valid; one is fixed the other way round from how it was suggested.

Key-coverage now checks manifest WRITES as well as reads. Copilot correctly
spotted that `ast.walk` ignored subscript context, so
`manifest["year"] = ...` (lib/songmeta.py) scored as a read — but the fix is
not to drop writes. A key core *writes* is spec surface pointed outward: it
lands in every pack we emit, so an undeclared one seeds the ecosystem with
non-spec data. Subscripts are now classified by ctx (Store = write, Load =
read) and both sets are checked, with distinct error messages. Today: 19
reads, 2 writes, all declared.

Workflow:
- persist-credentials: false on the repo checkout — the job runs repository
  code and never pushes (CodeRabbit / zizmor artipacked).
- .feedpak-spec-ref must be a full 40-char SHA. actions/checkout resolves
  branches and tags in `ref` too, so a non-SHA there would silently un-pin
  the spec — precisely what the file exists to prevent.
- Pin jsonschema==4.26.0, for the same reason the spec SHA is pinned: an
  upstream release must not redden this job on a PR that changed neither
  this repo nor the spec.

Script:
- check_forward() guards a missing examples/ dir instead of raising an
  unhandled FileNotFoundError.
- TemporaryDirectory() instead of mkdtemp(), so a local run doesn't leak.

topkoa 0dc9fd7ba8 docs: the fix for original_audio is removal, not adoption
The spec already carries the pre-separation mixdown as a stem
({id: full, file: stems/full.ogg}), so the key added a second, redundant
location for audio to a format that already had one. Adopting it into the
spec would make that permanent; the resolution in #933 is to remove it.

No behaviour change — the gate is agnostic about which way a violation
resolves, and only insists that one of the two happens deliberately and in
the open before the code merges. This just stops the exception entry, the
changelog, and the docs from presupposing adoption.

topkoa 22332bef22 ci: gate core against the feedpak spec
feedpak is published as an open format with its own repo, normative spec,
JSON Schemas, and reference validator. That makes the spec a contract with
everyone outside this repo: third-party packers, converters, and players
build against it, and it is meant to be the complete description of a pack.

Nothing enforced that. #583 added a manifest key (`original_audio`) that
core, lib/enrichment.py, and the stems plugin all now depend on, but which
was never added to the spec — so a spec-compliant pack stopped being a
fully-working pack, the reference validator could not warn authors about a
key it had never heard of, and third-party tooling began emitting an
`original/` directory reverse-engineered from an example in a code comment.
See #933.

We cannot mechanically prove core interprets a key the way the spec means.
We can prove three surface properties, and they cover the drift that
actually happens:

  1. key-coverage — every manifest key core reads is declared in the spec's
     manifest.schema.json (AST scan of lib/sloppak.py, lib/enrichment.py,
     lib/songmeta.py).
  2. forward — core's load_song() ingests every example pack the spec ships.
  3. reverse — every pack committed here passes the spec's own
     tools/validate.py (7/7 pass today).

The spec is pinned by SHA in .feedpak-spec-ref rather than tracked from its
default branch, so a change over there cannot redden an unrelated PR here;
bump it in its own PR, where a red result is precisely the signal that core
does not satisfy the new spec.

A gate with no legitimate way to say "yes, deliberately, not yet" gets
switched off the first time it blocks a release, so there are two escape
hatches: the reserved `x-` key prefix (always permitted, and it tells every
third-party packer the key is not stable surface), and
feedpak-spec-exceptions.yml, which requires a tracking issue per entry. An
exception that goes stale — the spec caught up, or core stopped reading the
key — fails the build, so the allowlist cannot become somewhere drift
quietly accumulates. `original_audio` is seeded there against #933 so the
gate lands green and starts blocking the next instance immediately, rather
than requiring #933 to be resolved first.

Dev/CI tooling only; never on the serve or Docker path (constitution
Principle I). jsonschema is installed in the CI job, not added to
requirements.txt.

topkoa a0278bd3a7 docs(panes): the lifecycle traps — isConnected lies, and re-injection duplicates
Three more rules, all learned by shipping the bug first. Every one of them
produced a symptom that pointed nowhere near its cause.

RULE 5 REWRITTEN — `isConnected` lies about a panel that is a pane, in BOTH
directions:

  - true when the panel is not here (it is in a pane window)
  - FALSE when the panel is perfectly fine — the host detaches the element the
    moment a pop-out starts, before the new window has loaded

Code that rebuilds on that `false` builds a SECOND panel while the host still
holds the first. Docking brings both home. The one the user can see is the
original, which the module no longer points at — so its close button closes the
other, invisible panel ("the X doesn't work"), and the chip gets re-attached to
the impostor ("the pop-out icon vanished"). Two baffling symptoms, one duplicate,
nothing in the stack trace.

Ask the pane system where the element is (`panes.isOpen(id)`), not the DOM.

RULE 6 (new) — a plugin that can be re-injected must be able to remove itself.
Without a teardown the second run duplicates every observer, timer and listener —
and leaves a stale pane registration, which is worse than untidy: `element` is
resolved LAZILY at open time, so the host gets a node from a dead instance. Pop
out, and it moves a panel nobody owns. Includes the teardown people forget:
panes.unregister().

RULE 1 EXTENDED — panel-internal id lookups. document.getElementById returns null
once the panel has moved, so every update it guards silently stops happening
while the user is looking at the panel. Search from the panel instead. Elements
outside the panel never move and are fine as they are — audit which is which.

topkoa 67e6b25c43 docs(panes): best practices for plugin authors
Every rule here is something that has already gone wrong on this feature —
mostly in core's own code, twice in the two plugins that adopted it first.
They are cheap to get right up front and miserable to diagnose later,
because a broken pane almost always LOOKS perfect.

The traps, and why each one is easy to walk into:

- Your code still runs in the main window. That is exactly why moving the
  element works at all — and exactly why `document.body.appendChild(tooltip)`
  inside a popped-out panel lands in the window the user is NOT looking at.

- Don't hide your own panel when it pops out. Core hides it and leaves a
  stub. A plugin that also hides it hides the node that just moved — which is
  precisely how core's own chip shipped a blank pop-out window.

- Use `hidden` or a class, not inline `display`, for show/hide. `.fb-paned`
  forces the panel visible while it is out; when it docks and that class is
  removed, an inline `display:none` reasserts itself and the panel returns
  invisible.

- `isConnected` does not mean "docked". A panel in a pane window IS connected,
  just not to this document. The test you meant is
  `el.ownerDocument === document`.

- `element` is a function so it can be resolved late: return the LIVE node, and
  re-attach the chip if you rebuild your panel (Camera Director rebuilds on
  every mode change).

- rAF is throttled while the main window is backgrounded — which it is, whenever
  the user is looking at your pane. Event-driven panels don't care; continuously
  animating ones will stutter exactly when they are the only thing on screen.

- Don't synchronise anything. One realm, one panel. Writing sync code means
  you have misunderstood the model.

Also states what core guarantees back, including the one that cost the most to
learn: the element is evacuated BEFORE the pane window's document is destroyed,
so it comes home alive rather than as a photograph of a panel with every
listener in its subtree silently gone.

topkoa 0955f0b6f2 fix(panes): keep a pane window in step with theme + interface scale
The pane window got a ONE-TIME snapshot of the app's theme classes and the
interface-scale custom property. The app changes both at runtime — Interface
size emits `scale:changed`, the theme emits `theme:changed` /
`v3:cosmetics-applied` — so an already-open pane went on rendering at the old
scale, in the old palette, the moment the user touched either.

"Looks identical" has to keep being true, not merely start out true.

A pane window now follows those three events for as long as it is open, and
stops on unplace(). The inline style is assigned wholesale rather than merged:
unlike the class lists (where pane.html's own `fb-pane-window` must survive),
there is nothing in the pane document's inline style to preserve — and
concatenating on every change would grow the attribute without bound as the
user dragged the scale slider.

Also: the dock's focus() always smooth-scrolled, ignoring
prefers-reduced-motion — which panes.css already honours for the card's flash
animation. A smooth scroll is motion too, and someone who asked for less of it
meant this as well.

topkoa 3a50e593bf fix(panes): fail fast when the pane window is unreachable; validate opts.header
Two from review.

1. _whenReady's own comment said a SecurityError means the pop-out is not
   reachable from this realm and "no amount of waiting will fix it" — and then
   it waited the full 10s deadline anyway. Ten seconds of a detached panel and a
   half-popped-out UI, for a condition we had already diagnosed as fatal.

   It now gives up after a 1s grace instead. Not instantly, deliberately: a
   throw *during* the navigation from about:blank to /pane would otherwise take
   down a pop-out that was about to work perfectly. A second is far more than
   that transition needs and far less than a user should spend staring at a
   detached panel.

2. attachChip() took opts.header on trust. It's a public plugin API, and a
   truthy non-Element header (a selector string, a wrapper object, a ref) is an
   easy mistake — one that surfaced as a confusing DOM exception from deep
   inside core instead of a TypeError naming the offending pane.

panes.css hides an empty dock (.fb-pane-dock.is-empty { display: none }), but
the element was created without the class — so between creation and the first
card it was a visible-to-CSS, announced-to-screen-readers role="region"
landmark containing nothing.

Harmless in practice today (the dock is created lazily, on the same tick as the
card that prompted it), but the CSS contract should hold from first paint rather
than from the first _syncEmpty(), and any future caller of dock() gets the right
thing for free.

topkoa de2a42bd35 fix(panes): coerce plugin-supplied pane sizes to numbers
`spec.width` / `spec.height` are plugin-controlled, and the window host builds
window.open()'s feature string by concatenation:

    'popup,width=' + spec.width + ',height=' + spec.height

`spec.width || 380` passed anything truthy straight through. So a width of
'300,menubar=1' would not merely be an invalid size — it would inject window
features. Less dramatically, any non-numeric value produced a malformed feature
string and a pane that failed to open for no visible reason.

They now go through _size(): Number, round, reject anything not finite and
positive, clamp to 120..4000. A hostile or careless value falls back to the
default instead of reaching window.open() at all.

Verified against the obvious inputs: '300,menubar=1' -> 380 (default), '300' ->
300, 0/-50/NaN/{}/'abc' -> 380, 1e9 -> 4000, 5 -> 120.

panes.css loads last, after tailwind/style/v3, and its rules win ties. In the

Cascade order is not a detail here. "Looks identical" has to include the order

/pane to load, and only then adopts the element in. But the manager emits
`panes:opened` as soon as place() returns, and the chip reacts by putting its
"popped out" stub where the element used to be.

So for that gap the user saw BOTH: the real panel still sitting in its
original spot, and a stub next to it claiming the panel had left. On a window
that never loads, that lasts the full 10s readiness timeout.

Detach the element as soon as we commit to moving it. That is not destructive:
the node keeps its owner document, its listeners and its closures — it is
simply out of the tree, waiting for a document to be adopted into. And if the
window never loads, closePane() puts it straight back at its home, which is
exactly what the failure path already does.

The dock host has no such gap; its place() moves the element synchronously.

topkoa 82aa8a757e fix(panes): harden the persisted host map against unsafe pane ids
A pane id is plugin-controlled, and it becomes a KEY in the persisted
{ paneId: hostId } map. `__proto__` and friends are not ids, they are booby
traps:

  - `map['__proto__'] = 'window'` on a plain object corrupts the map, and
    can reach Object.prototype.
  - `map[id]` on a polluted (or hand-edited) object can return a value straight
    off the prototype chain for a pane that was never remembered at all — so a
    pane could be "restored" to a host nobody ever put it in.

Three layers, because each is a one-liner:

  - Reject `__proto__` / `constructor` / `prototype` as pane ids at
    registration, so they never reach storage.
  - Re-key whatever comes out of localStorage onto a null-prototype object, so
    a corrupt or hand-edited value cannot smuggle a prototype in.
  - Read with an own-property check.

Also from the same review:

  - Removed `window.__fbPaneWindows`. It was exposed for pane-desktop.js back
    when that file needed to reach the window handles; the rewrite dropped that
    need and nothing has referenced it since. Dead global, and its comment
    described a collaborator that no longer exists.
  - Corrected the /pane cache comment. It claimed a stale page would leave the
    window blank, which stopped being true when the readiness check gained a
    `doc.body` fallback — it would still work, just without the pane window's
    own layout. A comment that describes a failure mode the code no longer has
    is worse than no comment.

topkoa cb425ed48d fix(panes): don't hide a docked pane; don't force display; restore visibility
Six more findings from CodeRabbit on #928. Three are real bugs.

1. THE CHIP HID DOCKED PANES. `_onOpened` decided "did the pane take my
   element?" from `ownerDocument !== document`. That is true for a pane in a
   pop-out window — and false for a pane moved into the DOCK, which lives in
   this very document. So docking a pane stamped `.fb-pane-detached`
   (display:none !important) onto the panel the user was looking at, and put
   the stub next to it instead of at its home.

   The element cannot answer this question — `isConnected` is true in a pane
   window, `ownerDocument` is this one in the dock. Both were live bugs. Ask
   the manager, which knows exactly what it handed to the host:
   `panes.elementOf(id)`. That holds for every host, and for reconciling after
   the fact (detail == null), which is what a plugin rebuilding its panel
   mid-pop-out triggers.

2. `.fb-paned` FORCED `display: block !important`. A panel that is
   `display:flex` or `grid` would be silently re-laid-out while detached —
   the exact opposite of "placement only", and precisely the kind of surprise
   this feature exists to avoid. Removed.

   Making a hidden panel visible is a separate job, and it now belongs to the
   manager, which does it without touching the panel's display MODE: clear
   `hidden`, and clear an inline `display:none` if that is how the panel hides.

3. VISIBILITY IS NOW RESTORED. The hosts used to set `el.hidden = false` and
   never put it back, so the docs' "core only changes placement" was a lie and
   a panel's hidden state was quietly lost. The manager stashes both `hidden`
   and the inline `display` on open and restores them on dock: a panel that was
   closed when you opened its pane from the tray goes back to being closed; one
   that was open stays open.

Plus:

- The launcher rebuilt its whole list on every panes:opened/closed — including
  the one fired by clicking a button in that list — destroying the button under
  the user's finger and dropping focus to <body>. It now restores focus to the
  toggled pane's button.
- `_copyStyles` cloned every stylesheet link, including the panes.css that
  pane.html already loads. Skip sheets the pane document already has.
- Docs: the chip may route to the DOCK, not always a window (it goes through
  detach() → the host router). `header` precedence was documented backwards —
  an explicit `header` wins. And the visibility contract above is now written
  down rather than being a surprise.

topkoa 859b0036e5 fix(panes): review fixes — stranded elements, duplicate listener, class clobber
Three real findings from CodeRabbit on #928, all in current code.

1. closePane() adopted the element out of the pane window ONLY when its
   original home was still connected. If the panel never had a parent (a
   plugin that builds it lazily and hands it straight over) or its container
   was torn down while the pane was out (a screen change), the whole block was
   skipped — leaving the element inside a window we then close, which strips
   every listener in its subtree. That is exactly the "comes home dead" failure
   this ordering exists to prevent; the guard just moved it from the common
   path to the rare one, where it is far harder to spot.

   Adopting and re-homing are two different jobs and only one of them is
   allowed to fail. Adopt UNCONDITIONALLY — that is what rescues the element —
   and insert only when there is somewhere to insert it. With no home the
   element ends up owned by this document but not in it: detached, intact,
   listeners alive, ready for the plugin to re-insert.

2. The pane window's `beforeunload` handler was registered TWICE, comment block
   and all — a bad scripted edit on my part. Harmless (the handler is
   idempotent via panes.isOpen) but dead duplicate code. Also fixed the stale
   comment further down that still claimed there was no beforeunload listener
   at all.

3. _copyStyles ASSIGNED className on the pane document's <html> and <body>
   instead of merging. pane.html sets `class="fb-pane-window"` on <html>, and
   panes.css hangs the pane window's own chrome off exactly that — so copying
   the app's classes over it silently took the pane window's own layout with
   them. Merge both class lists, and append the interface-scale inline style
   rather than replacing the attribute.

Also guarded the docs' integration example behind a feedBack.panes check: the
doc says the API is optional, and then showed an example that would throw on a
host without it.

Not applicable (reviewed against e5cbea2, the branch's first commit, before the
rebuild): the prototype-pollution findings in pane-bridge.js and pane-mirror.js,
and the `panes[]` manifest validation in plugins/__init__.py. All three files are
gone — 188bdaa deleted the entire cross-realm bridge, mirrorGlobal, and manifest
layer when panes switched to moving the real DOM node.

topkoa 1e5282e27e fix(panes): get the element out before the pane window's document dies
Docking a popped-out panel brought it home DEAD. It rendered perfectly —
right markup, right size, right place — and every control in it was inert:
the close button, the sliders, the presets, even the pop-out chip. A
photograph of a panel.

Closing a pane window tears down its document, and the panel was still
inside it. The node itself survives (the manager holds a reference), but
every event listener in its subtree goes with the document that hosted
them. Two paths did this:

  1. closePane() called the host's unplace() — which closes the window —
     BEFORE adopting the element back. Order is now reversed, and the
     comment says why so nobody helpfully "tidies" it back.

  2. The user closing the pane window themselves was only noticed by the
     `closed` poll, which by definition runs AFTER the document is gone.
     The window now gets a `beforeunload` listener that brings the element
     home while its document is still alive.

That listener has to be attached AFTER /pane loads: window.open() hands
back a throwaway about:blank document, and anything registered on it is
discarded when the real page replaces it. This is the same trap that made
the pane window blank in the first place — adopt into about:blank and the
panel is destroyed a moment later — and it is now handled in both places.

The `closed` poll stays, but only as a last-resort net for a CRASHED pane
window, where nothing can be saved.

Also fixed while chasing this:

  - The chip stamped `.fb-pane-detached` (display:none !important) onto the
    element to hide it in the main window — and that element is the one we
    move, so the class travelled with it and blanked the pane window. The
    chip now only hides an element the pane did NOT take, and marks the hole
    with its stub otherwise. "Did not take" is an ownerDocument test, not
    isConnected: a panel sitting in a pane window IS connected, just not
    here, and a plugin that rebuilds its panel (Camera Director does, on
    every mode change) re-runs attachChip while popped out.

  - The stub was inserted "before the element", which is nowhere — the
    element has left the document. The manager now hands over the element's
    recorded home, and the stub goes there.

  - GET /pane sent no cache headers. A stale copy is especially nasty here:
    the opener waits for an element inside that page before adopting, so an
    old cached version means the pane window just sits there blank.

Verified in the desktop app: pop out, use the controls in the pane window,
dock back, use them again. Panel comes home alive.

topkoa 9e9f0fdac6 fix(panes): adopt into the real pane document, not about:blank
Both pop-outs opened blank.

window.open() returns immediately, and the window it hands back already has
a document — an `about:blank` one, whose readyState is 'complete'. So the
host cheerfully adopted the panel into THAT, it worked for a few
milliseconds, and then /pane finished loading, replaced the document, and
took the panel with it. Blank window, vanished element.

Waiting for 'load' is no better: it may already have fired for about:blank
before we could listen.

So don't trust readyState and don't trust 'load' — wait for the one thing
that exists only in the document we actually want: pane.html's
#fb-pane-root. Poll for it (guarding the cross-document window while it is
mid-swap), give up after 10s, and on failure bring the element home rather
than stranding it in a window that never loaded.

Also drop the popup's 'beforeunload' listener: it was registered on the
about:blank window and discarded along with it, so it never fired. The
`closed` poll is what notices a user shutting a pane window — as it must be
anyway, since a crashed renderer never says goodbye either.

topkoa 188bdaa837 feat(panes)!: move the real element, instead of rebuilding it
The first cut of this got the model wrong. A pane was a SECOND
implementation of the plugin's panel — its own sliders, its own styling,
driven over a cross-realm bridge (ctx, a state store, capability RPC,
mirrorGlobal, a stream sampler). Popping out gave you something that
resembled the panel you popped, and every feature it did not reimplement
(presets, tabs, EQ, language) was simply gone.

What a user wants from "pop this out" is the thing they popped out.

So: MOVE THE REAL ELEMENT. Same-origin windows can adopt each other's
nodes, and an adopted node keeps its event listeners and its closures.
The panel goes on running the plugin's own code, against the plugin's own
state, in the plugin's own realm — it is merely being DISPLAYED in another
window. Copy the app's stylesheets into that window and it looks identical
too, because it is identical.

The plugin's side collapses to two lines:

    feedBack.panes.register({ id, title, element: () => panelEl });
    feedBack.panes.attachChip(panelEl, id);

and everything comes along: the CSS, the listeners, the presets, the
state. Nothing to keep in step, because there is no second copy.

Deleted, all of it now pointless: pane-bridge (ctx + transports), pane-hub
(the cross-realm server), pane-runtime (the pane realm's boot), pane-streams
(the rAF sampler that existed because an AnalyserNode can't cross a window),
pane-mirror (mirrorGlobal), pane-plugins + the manifest `panes[]` key and its
server-side validation, panes.state(), and both built-in demo panes. ~1200
lines. None of it was wrong — it was all correct machinery for the wrong
problem.

Consequences worth knowing:

- The window MUST be opened by the renderer with window.open(), not by the
  desktop's main process: a window we did not open gives this realm no handle
  to its document, and without the handle there is nothing to adopt into.
  Electron turns the same-origin window.open() into a real BrowserWindow
  anyway (setWindowOpenHandler → 'allow'), so we get the OS window AND the
  live DOM link. The desktop side finds it by frame name.
- `.fb-paned` neutralises PLACEMENT only (position/inset/width/z-index/shadow).
  A plugin panel is nearly always a fixed overlay pinned to a corner of the
  app; alone in a 380px window that positioning is nonsense. Colours, borders,
  padding, fonts and the panel's own internal layout are untouched — the whole
  promise is that what you popped out is what you get.
- The element is returned to its EXACT home on dock: same parent, same position
  among its siblings.
- The plugin's code still runs in the main window. So a document.body
  .appendChild() inside a panel (a tooltip, a popover) lands in the main
  window, not the pane — anchor to the panel instead. And a continuously
  animating panel may run slowly while the main window is backgrounded, since
  its rAF lives there. Both documented.

topkoa 330995588c feat(panes): panes.state(id) — let a plugin apply its own pane's values
mirrorGlobal covers the case where a pane drives a plain global that some
renderer reads each frame. It does not cover the far more common one: a
plugin whose MAIN-realm code is the authority — it clamps, it persists, it
emits events, it owns the audio graph or the camera rig — and which must
therefore APPLY the pane's values itself rather than have core splat them
somewhere.

Camera Director is the case that forced this. Its brain is the sole writer
of the camera store, the sole broadcaster on splitscreen's channel, and the
only thing that clamps an axis to its legal range. A pane cannot write
window.__h3dCamCtl behind its back without desynchronising its presets, its
persistence, and the panel's own sliders — and running the brain inside the
pane realm would make it a SECOND store writer and a second broadcaster,
racing the real one.

So: `panes.state(id)` hands the main realm the open pane's store
(get/set/all/subscribe). A plugin seeds it on `panes:opened`, subscribes,
and applies what comes back through its own API. The pane stays
realm-agnostic — it only ever touches ctx.state — and the plugin stays the
single source of truth.

For that to work, the hub now broadcasts EVERY change to the store, not just
the ones a pane asked for: it subscribes to the store on connect rather than
echoing pane-originated writes by hand. A value the plugin clamps or corrects
therefore reaches the pane window immediately, and there is exactly one path
by which state arrives in a pane — so it cannot drift.

topkoa 254e26bb3a feat(panes): mirrorGlobal, manifest-declared panes, and the plugin docs
Three things a plugin needs before it can actually use panes.

## mirrorGlobal — the camera-director problem

The 3D highways read their free camera from a plain global,
`window.__h3dCamCtl` (highway_3d/FREECAM_BRIDGE.md), once per frame in
_resolveFreeCam(). A camera panel in the main window just writes that
object and the camera moves. A panel in a POP-OUT window cannot:
window.__h3dCamCtl there is a different object in a different realm, and
writing it moves nothing.

So a pane declares one field — `mirrorGlobal: '__h3dCamCtl'` — and
pane-mirror.js (main realm, where the renderers live) copies that pane's
state onto the global whenever it changes. highway_3d, keys_highway_3d
and drum_highway_3d are NOT modified and do not know panes exist.

The rule that makes it work: MUTATE THE OBJECT, NEVER REPLACE IT. A
renderer may be holding the reference, and swapping in a new object would
leave it reading an orphan. Keys the pane doesn't set are left alone
rather than deleted — the global may carry a renderer's own bookkeeping.
Closing the pane deliberately leaves the global as-is: closing the camera
panel should not snap the camera back to a default, which is exactly what
happens today (nobody clears __h3dCamCtl).

## Manifest-declared panes

    "panes": [{ "id": "camera_director", "title": "Camera Director",
                "script": "panes/camera.js", "mirrorGlobal": "__h3dCamCtl" }]

Declaring a pane beats calling panes.register() from screen.js because it
becomes openable FROM THE RAIL OR THE TRAY WITHOUT THE PLUGIN'S SCREEN
EVER HAVING BEEN VISITED — core registers a stub from the manifest and
fetches the script only when the user opens it. A pane you can only reach
by first navigating to the screen it was meant to replace is not much of a
pane.

The script sets `window.feedBackPane_<id> = { mount, unmount }`, mirroring
the existing window.feedBackViz_<id> convention, and the SAME file is what
a pop-out window loads in its own realm.

`script` is validated as a relpath under the plugin's src/ and served
through the sandboxed /api/plugins/<id>/src/ route — the containment rule
`styles` already has for assets/. Traversal, absolute paths, drive letters,
backslashes and non-.js are rejected; a bad entry is dropped with a warning
rather than failing the whole plugin, because one malformed pane should not
cost the user a working plugin.

Note the projection is written TWICE — _nav_entry() and the /api/plugins
route re-project independently — so panes had to be added to both, plus the
pending branch (a pane can be opened while its plugin is still installing
deps; the script is fetched on open, not at discovery).

## docs/plugin-panes.md

The contract, and the one rule it all hangs on: mount(root, ctx) runs in a
realm that may not have the app in it. Everything comes through ctx, or the
pane works docked and silently dies popped out.

Verified: manifest validation rejects ../.., C:\, non-.js, dupes and
missing fields while passing a good entry; /api/plugins projects panes[] for
all 20 plugins. mirrorGlobal mutates the global IN PLACE — a reference held
the way _resolveFreeCam holds it sees the change, and a renderer's own field
on that object survives — both for a local write and for a write arriving
over the channel from a pop-out realm.

pytest: 2401 passed, 8 failed — all 8 reproduce on a clean main (including
the one in tests/test_plugins.py) and are unrelated.

topkoa d508380532 feat(panes): desktop host — real windows and the system tray
Registers a `desktop` pane host at priority 20, above the browser pop-up
host (10) and the dock (0), whenever the Electron bridge exposes
feedBackDesktop.panes. A popped-out pane then gets a real BrowserWindow:
it remembers where you put it, can float above everything, minimizes to
the system tray, and appears in the tray's menu.

In a plain browser — or on an older desktop build that predates the
bridge — this file registers nothing and the browser pop-up host handles
detach exactly as before. Nothing else in the pane system changes. That
is what the host registry is for.

Two things only this realm can decide, so it owns them:

- The user closed a pane window (or it crashed). Close the pane, or the
  dialog its pop-out chip hid never comes back and the user is left with
  no way to reach their own UI.
- The tray asked to toggle a pane it has no window for. Main cannot know
  what opening one means — the pane might belong in the dock — so it asks.

Unlike a browser pop-up, this host needs no user gesture, so it sets
autoRestore: true — a pane you left popped out comes back popped out,
where you left it, on the next launch.

Pairs with got-feedback/feedBack-desktop#103.

topkoa fefb9051a4 feat(panes): pop-out windows — the pane realm, hub, and remote transport
A pane can now leave the main window entirely. Same `mount(root, ctx)`,
same file, different JS realm — which is what the ctx-only contract in the
previous commit was for.

## A purpose-built document, not the app shell with a flag on it

`GET /pane` serves static/panes/pane.html: the bridge, the runtime, and
the pane's own script. No highway, no library, no v3 shell, no <audio>,
no Tailwind.

The splitscreen follower takes the other road — it reloads the whole app
at `/?ssFollower=1` and hides what it doesn't want — and pays for it with
an anti-flash block that must run before any script parses (index.html),
bail-outs in app.js and shell.js, and ~40 lines of CSS hiding core
elements by id. It loads the entire app to throw it away. A pane window
has nothing to throw away, so it boots in milliseconds and there is
nothing to flash.

The cost is that `window.feedBack` in a pane realm is a deliberate,
documented SUBSET. The runtime installs exactly what a pane is promised —
`panes.register`, and the no-op chip/dock calls a shared script may make
at load — so a pane reaching for something it was never given fails
loudly at authoring time instead of subtly at runtime.

## The channel

BroadcastChannel('feedback-panes'), same origin. This works only because
Electron's setWindowOpenHandler returns `action: 'allow'` for same-origin
URLs: `deny` would push the window to the system browser, a different
Chromium instance, where BroadcastChannel cannot reach it and the pane
would silently never sync. That flag is load-bearing.

  hello -> snapshot   resync-on-open, always. The snapshot is the only way
                      the pane realm learns anything.
  state               main is authoritative. A pane's write is a REQUEST;
                      main applies it and echoes to every realm, so a
                      losing write self-corrects instead of splitting brain.
  rpc / rpc:reply     ctx.call() -> the capability bus, with a 10s deadline.
                      Without one, a main window that died mid-call leaves
                      the pane's promise pending forever.
  event               allowlisted bus events, JSON-safe. A CustomEvent
                      carrying a DOM node (highway:canvas-replaced does)
                      would throw on postMessage and take the channel down
                      for everyone, so detail is round-tripped through JSON.
  stream              one coalesced message per pane per frame, OVERWRITING
                      anything not yet flushed. Queueing would build a
                      backlog: Chromium throttles a backgrounded window, and
                      the main window is exactly what's backgrounded while
                      the user looks at the pane.
  sub / unsub         refcounts the main-realm sampler.
  bye                 both directions.

## The follower clock

The pane extrapolates between broadcasts: anchor + observedRate * elapsed,
capped at 2s. observedRate is learned from the broadcasts themselves
(dt/dwall) so it tracks the speed slider without being told about it, and
seeks/pauses are excluded from the fit — a jump is not a tempo. Capping it
means a dead main window decays into a frozen clock rather than one that
confidently runs away. This is splitscreen's hard-won trick, generalized:
panes just call ctx.playhead().

## Failure modes, all of them

- Main window closes -> `bye {main-closed}` and the pane says so plainly,
  rather than showing a frozen playhead that looks live. The host also
  closes its windows outright; a pane that cannot be fed should not be on
  screen.
- Pane window X'd or crashed -> a `closed` poll reaps it (a crashed
  renderer never sends `bye`), the pane closes, and the chip's dialog comes
  back. Without this the user's dialog stays hidden with no way back.
- Popup blocked -> a toast, and we bail BEFORE the manager records
  anything, so the caller's dialog stays exactly where it was.
- Nobody answers `hello` in 5s -> the window says so instead of spinning.
- A pane with no `script` is a closure in this realm and cannot honestly
  cross a window boundary. The window host declines it (canHost) and the
  router falls back to the dock.
- A browser blocks window.open() outside a user gesture, so a popped-out
  pane cannot be auto-restored on page load — it would only ever produce a
  "blocked" toast. Such a pane comes back in the DOCK, and the chip pops it
  out again on the next click. (autoRestore: false. The desktop host will
  set it true.)

Hosts may now declare `remote: true`, meaning the pane's mount() runs in
another realm: the manager then owns only the authoritative state store and
never calls mount() itself. That is the seam the Electron BrowserWindow +
tray host drops into next, with no change here.

Verified: popped Now Playing and Mixer into real windows. The pane realm has
no window.highway, no capability bus and no <audio>, yet the Mixer renders
its faders via ctx.call('audio-mix','list-faders') across the channel — and
dragging that fader IN THE PANE WINDOW moved the main window's song volume
to 55 and persisted it. Closing the pane window un-hid the mixer dialog,
removed the stub and restored the chip, while the other pane window stayed
open.

Byron GamatosandGitHub e2215df753 feat(career): bundle dive bar venue pack (#927) 2026-07-12 22:58:04 +02:00
topkoa e5cbea2e9f feat(panes): core detachable pane system + pop-out chip
The option-heavy player UIs (mixer, camera director, viz, audio routing)
all live in the rail popovers, which are exclusive: openPopFor() closes
the last one before opening the next. You cannot watch the mixer while
riding the camera, and both vanish the moment you look at the highway.

Add `window.feedBack.panes` — a core registry for live UI that is
authored once as `mount(root, ctx)` and hosted anywhere. Panes are
non-exclusive, and they survive song switches structurally: the dock is a
body child outside every .screen, so the per-song teardown never sees it.

The adoption cost for a plugin is two calls:

    feedBack.panes.register({ id, title, icon, mount, unmount });
    feedBack.panes.attachChip(myExistingDialogEl, id);

attachChip injects THE standard pop-out chip. Clicking it opens the pane
and hides the plugin's dialog, leaving a stub to bring it back. Core owns
the hide/restore, so every plugin's pop-out looks and behaves the same —
which is the point. It hides via a dedicated .fb-pane-detached class, not
.hidden/[hidden], because the dialogs we attach to already toggle those.

Everything a pane may touch arrives through `ctx` — never a global. That
is what will let the same mount() run inside a pop-out window, a separate
JS realm with no window.feedBack, no window.highway and no audio graph:

  ctx.call(domain, cmd, payload)  -> the capability bus
  ctx.on(event, fn)              -> the feedBack bus (allowlisted)
  ctx.subscribe(stream, fn)      -> playhead / meters
  ctx.state.get/set              -> persisted, main realm is the only writer
  ctx.playhead(), ctx.song(), ctx.toast(), ctx.close()

ctx tracks every subscription it hands out and drops them on unmount, so
a pane cannot leak listeners across a dock/undock cycle.

Streams exist because an AnalyserNode cannot cross a window boundary:
levels are reduced to numbers in the realm that owns the audio graph.
One shared rAF loop, refcounted against live subscriptions, dirty-checked
before fan-out, and stopped dead when the last pane closes.

Hosts register themselves with the manager rather than being imported by
it — the dock lands at priority 0 (the floor, always available), so the
OS pane window can drop in later without this code changing.

Ships two built-in panes: Now Playing (the reference pane — reads the bus,
a stream, and levels, and touches no globals) and Mixer (the same faders
as the rail, via ctx.call('audio-mix', ...), with the chip attached to the
real #mixer-control). Plus a "Panes" rail popover to open panes that have
no dialog of their own; the system tray will mirror that list.

Note the dock sits at z-index 110, not on the docs/plugin-v3-ui.md ladder
(transport 20, rail 30, popovers 40) — those live INSIDE #player's
stacking context, and #player is itself fixed at z-index 100. A dock below
100 is invisible on the one screen panes exist for. Body-level ladder:
#player 100 < dock 110 < toasts 120 < modals 200.

Pop-out windows, the system tray, manifest-declared panes and mirrorGlobal
(the window.__h3dCamCtl proxy the camera director needs) follow.

ea0ca94742 feat(career): career plugin — stars, venue tiers, pack downloads (career mode 2/3) (#907)
* feat(career): career plugin — stars from song_stats, venue tiers, pack downloads (career mode PR2)

Bundled plugin: per-song stars from best_accuracy (60/75/85% → 1/2/3★),
cumulative stars unlock bar → club → arena (data-driven venues.json).
Venue packs (UE-rendered crowd loops) download on demand to
CONFIG_DIR/plugin_uploads/career/ on a background thread with sha256 +
zip-slip validation, served via FileResponse. Career screen (promoted
sidebar entry) shows progress and pushes the active venue's manifest
into the crowd video layer (v3VenueCrowd, PR1) — degrades cleanly when
either side is absent. Pack URLs land in venues.json in PR3.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(career): keep manifest cleanup path alive on delete; badge only for installed venues

Codex preflight: nulling _appliedManifestVenue on delete skipped
pushCrowdManifest's setManifest(null) cleanup, leaving the crowd layer on
a deleted pack; and the 'playing here' badge showed for an override venue
whose pack was removed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(career): generation-guard in-flight manifest fetches

Codex preflight: a manifest fetch resolving after a newer refresh (pack
deleted, venue switched) could re-apply a stale pack over the user's
newer selection — fetches now carry a generation token and bail when
superseded.

* fix(career): exclude orphaned song_stats from star totals

Codex preflight: scans hide rather than delete stats of removed songs, so
stars now apply the same existing-song filter other stats surfaces use
(filename IN (SELECT filename FROM songs)).

Byron's progression tuning: club at 50★, arena at 150★. /state now
returns star_detail rows (title/artist joined from the library, stars,
best accuracy, next-star threshold) sorted closest-to-next-star first,
and the career screen renders a collection panel: tier summary plus a
per-song list with a 'N% to next star' practice hint.

* feat(career): venue select/unselect UX, intro manifest support, fullmatch guards

- 'Play here' now also defaults the visualization to Venue (remembering
  the prior viz); active venues show 'Leave venue' which restores it and
  sets the '__none__' override so no installed venue silently reapplies.
- Pack manifests may ship an intro block (flyover video + ambience mp3);
  files validate like loops/stingers, .mp3 added to the serving whitelist.
- Codex preflight: whitelist regexes use fullmatch (trailing-newline names
  could validate but 500 on serving).

e779c72396 feat(venue): reactive crowd video layer behind the 3D highway (career mode 1/3) (#905)
* feat(venue): reactive crowd video layer behind the 3D highway (career mode PR1)

Two crossfading video backdrop planes in the highway_3d venue background
style, driven by a new venue-crowd.js state machine that maps
v3:live-performance-state to crowd states (bored/neutral/engaged/ecstatic)
with 3s stability + 8s dwell hysteresis, plus one-shot reaction stingers
on streak milestones and end-of-song accuracy. Inert without a venue pack
manifest (career plugin, PR2) or the feedBack-venue-crowd-dev flag — the
static bg plate behaves exactly as before.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): retry renderer binding + preserve mid-stinger transitions

Codex preflight P2s: (1) videos created before highway_3d registered its
globals never reached the backdrop planes — binding is now idempotent and
retried from start/perf-event/re-activation paths; (2) a crowd-state
switch committing while a stinger played was dropped because the machine
had already advanced — it is now deferred and played when the stinger ends.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): per-video load tokens + unbind renderer on stop

Codex preflight round 2: (1) the global load token let a stinger cancel a
committed loop load on the other layer — tokens are now per-element, and a
stinger preempting an in-flight loop on its own layer requeues that loop
for when the stinger ends; (2) setManifest(null)/deactivate left the last
crowd frame bound and visible over the static plate — stop() now unbinds
both layers from the renderer and zeroes the mix.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): flush deferred loop on stinger failure, source accuracy from perf events

Codex preflight round 3: (1) a failed/timed-out stinger left a deferred
loop switch queued forever; the failure path now flushes it. (2)
stats:recorded only carries {filename, arrangement}, so the end-of-song
reaction now uses the accuracyPct from the song's last
v3:live-performance-state event (a real percentage) instead of a field
that never existed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): requeue mid-crossfade loops preempted by stingers; hard-stop on manifest swap

Codex preflight round 4: (1) idleLayer() still points at the fading-in
layer during a crossfade, so a stinger firing mid-fade overwrote the new
loop with nothing requeued — the fading loop is now tracked and requeued
like an in-flight load; (2) swapping venue packs while active now goes
through stop() so _stopGen invalidates the old manifest's in-flight loads.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): generation-gate stinger handlers; recrop on video size change

Codex preflight round 5: (1) an ended/timeout handler orphaned by stop()
could fire into a later stinger's lifecycle on the reused element — handlers
now detach unconditionally and carry a generation token; (2) the renderer
only re-applied cover-crop on camera aspect changes, so a src swap with a
different intrinsic size kept stale repeat/offset — it now recrops when
videoWidth/Height change.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): bail loop-fade completion when a stinger preempted the layer

Codex preflight round 6: the loop crossfade's completion callback could
still run between a stinger's start and its canplaythrough, promoting the
stinger's layer to active and pausing the real loop — it now bails when
the fading loop was preempted.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): keep rear video layer opaque during crossfades

Two half-transparent layers let the static bg plate bleed through (~25%
at mid-fade) — visible as a flash of the old still image on every state
transition. The crossfade is now always the front layer fading over an
opaque rear layer.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): reset active layer with mix on stop

Codex preflight: stop() zeroed the mix but left _activeLayer at 1, so a
restart flashed layer 0's stale frame until the new loop loaded.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): reset crowd mood to neutral on song load

Codex preflight: a song ending in ecstatic/bored left the next song's
crowd stuck in that mood until the hysteresis window passed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): cancel in-flight fade when a stinger preempts it

Codex preflight: the orphaned ramp kept pushing the mix toward the layer
whose src the stinger had just replaced.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): don't let null accuracy resets wipe the end-of-song value

Codex preflight: Number(null) is 0, so idle HUD resets overwrote
_lastAccuracyPct before stats:recorded consumed it, suppressing the
end-of-song stinger.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): abort stale stinger state on song load

Codex preflight: a stinger straddling a song change could fade back into
the previous song's layer or flush its pending loop.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): always detach load listeners, gate only the callback

Codex preflight: superseded loads left canplaythrough/error listeners
attached to the persistent video elements — unbounded growth over a
session.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(venue-crowd): flyover intro with crowd-ambience ducking

On song:loaded, an optional pack intro plays once: a camera flyover video
(idle layer, one-shot) with bar-crowd ambience audio that ducks out on
song:play, near the flyover's landing, or at handoff — whichever first.
Machine commits and stingers defer during the intro; stop()/song-change
abort it. Packs without an intro behave as before.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): fall back to the loop when the intro fails to load

Codex preflight: a failed/timed-out intro left the song with no crowd
loop at all.

ChrisBeWithYouandClaude Fable 5 ffc52f13ce Harden freqs_to_midis against NaN/Inf; badges read exact tuningMidis
Follow-ups to #829 (CodeRabbit's review nit + the consumer adoption the PR
body promised):

- freqs_to_midis: reject non-finite frequencies (NaN/Infinity) — a provider
  handing one through would otherwise raise inside int(round(...)) and 500
  GET /api/tunings. Tests cover nan/inf/-inf alongside the existing garbage
  cases.

- v3 instrument badge: TUNING_NOTE now prefers the exact integer midis the
  server serves (tuningMidis) over reconstructing the note from the lowest
  string's frequency via log2 against a hardcoded 440 — which can land a
  semitone off at non-440 reference pitches. Frequency path kept as the
  fallback for older cached responses.

8d3db5f42c fix(nav): nobody may monkey-patch window.showScreen — add screen:changing, make the shell listen (#924) (#925)
ship-ci / ci (push) Waiting to run
* fix(nav): the library sometimes showed the legacy screen — map 'home' inside showScreen

Testers: "randomly, when moving to the library from another menu option, the library shows the
old interface — never when a song ends."

━━━ WHAT WAS ACTUALLY HAPPENING ━━━

#home is the PRE-V3 library screen. The v3 shell replaced it with #v3-songs, and the mapping DID
exist — but only inside WRAPPERS on window.showScreen, and only for callers that go through
`window`. THREE independent parties monkey-patch it, each capturing whatever happens to be there
at the time:

    app.js publishes the raw function
      -> shell.js wraps it, adding the home -> v3-songs mapping
      -> the stems plugin wraps it AGAIN (src/main.js:1029), capturing the current value

Plugins load ASYNCHRONOUSLY. The chain links up in whatever order the race settles, and any
capture taken before shell.js installs — or any re-assignment after it — silently drops the
mapping. Hence "randomly".

AND THE INTERNAL CALLERS NEVER TOUCHED window.showScreen AT ALL. closeCurrentSong and the
Esc-from-settings shortcut call the IMPORTED showScreen, which no wrapper ever sees. Reproduced
in a browser: the unwrapped function with 'home' lands on the dead legacy screen EVERY time.

"Never when a song ends" is the tell, and it is what identified the mechanism: closeCurrentSong
resolves its target through _resolvePlayerOrigin(), which ALREADY applies this mapping. That one
path was fine — which is exactly why the bug looked random rather than total.

PRE-EXISTING, not a regression from the module carve: the onclick="showScreen('home')" links and
the wrapper-only mapping both date to 2026-06-22.

━━━ THE FIX ━━━

The guard lives inside showScreen now: ONE place, in the function every caller routes through,
instead of a chain of monkey-patches that must each remember. Wrapper order stops mattering, and
the module-internal callers are covered for the first time.

Verified in a browser: the raw, unwrapped showScreen('home') — which reproduced as #home — now
lands on #v3-songs, and cannot be undone by any wrapper order.

━━━ AND A [P1] I INTRODUCED, WHICH CODEX CAUGHT ━━━

My first cut mapped BOTH 'home' and 'v3-home', copied straight from _resolvePlayerOrigin.

That is correct THERE and wrong HERE. _resolvePlayerOrigin computes where to RETURN TO after a
song, and landing on the Songs list from the dashboard is the right behaviour. But #v3-home is
the v3 DASHBOARD — a real screen that the shell's Home nav, the onboarding tour and the dashboard
re-render listener all target. Redirecting it would have made Home unreachable.

A LEGACY ALIAS IS NOT THE SAME THING AS A RETURN TARGET. Only 'home' is mapped now, and a test
pins that: re-adding 'v3-home' to the guard fails it.

4 tests, bite-tested both ways.

* fix(nav): nobody may monkey-patch window.showScreen — add screen:changing, make the shell listen (#924)

window.showScreen was wrapped by THREE independent parties, each capturing whatever happened to be
there at the time:

    app.js publishes the raw function
      -> static/v3/shell.js wrapped it (to call syncActive, and to map home -> v3-songs)
      -> the stems plugin wrapped it AGAIN (to tear down on leaving the player)

Plugins load ASYNCHRONOUSLY, so the chain linked up in whatever order the race settled. A capture
taken before shell.js installed silently dropped the mapping it carried — and the library opened on
the dead legacy #home screen. Testers saw that as "randomly, the library shows the old interface"
(#923).

#923 fixed the symptom by moving the mapping inside showScreen. This removes the CAUSE: neither
wrapper ever needed to be one.

━━━ TWO EVENTS, AND THE DISTINCTION IS THE WHOLE POINT ━━━

    screen:changing  emitted BEFORE anything happens. "I am leaving `from`." Teardown/cancel here.
    screen:changed   emitted after the DOM and data settle. "I am on `id`." Now carries `from`.

screen:changing is new, and it exists because Codex caught me collapsing the two. The stems plugin
tore down its audio graph BEFORE showScreen did anything; screen:changed fires at the very END,
after core awaits library and provider loads — so moving the plugin onto it would have delayed
teardown behind a slow fetch, or skipped it entirely if that fetch threw, and stems would keep
playing on a non-player screen. A test pins the ordering: screen:changing must precede the first
await.

shell.js is a plain screen:changed listener now, like app.js, audio-mixer.js and tour-engine.js
already were. window.showScreen is an unwrapped function again, and tests/js/
no_showscreen_monkeypatch.test.js fails CI if anything in static/ ever assigns to it again — so the
hazard is structurally impossible rather than merely avoided.

━━━ AND A FALLBACK THAT COULD NEVER FIRE ━━━

My retry-if-the-bus-is-late path listened for `slopsmith:capabilities:ready`. Core dispatches
`feedBack:capabilities:ready` (capabilities.js:1536) — the slopsmith: name is the PRE-DMCA event
and nothing has emitted it since the rename. Codex caught it. A guard that cannot fire is worse
than no guard: it reads as protection and is decoration.

(The same dead-event bug turned out to be sitting in THREE of the stems plugin's fallbacks, where
it has silently disabled its lifecycle wiring whenever the bus was late. Fixed in
feedback-plugin-stems#38.)

VERIFIED. A/B against origin/main: the nav highlight and topbar title follow IDENTICALLY with
shell.js as a listener; screen:changing -> screen:changed fire in order with the right {id, from};
window.showScreen is unwrapped; and showScreen('home') still lands on v3-songs.

57e7db5c2a refactor(app): carve the keyboard-shortcuts subsystem into static/js/shortcuts.js (R3d) (#922)
19 declarations + 23 TOP-LEVEL STATEMENTS. 922 lines. app.js 3,243 -> 2,325 (-28%).

The panel registry, both global keydown dispatchers, the library arrow-nav, and the whole
plugin-facing shortcut API.

━━━ MOST OF THIS SUBSYSTEM WAS NOT DECLARATIONS ━━━

A declaration-seeded dependency closure reports this cluster as 10 names, 246 lines.
It is 42 statements and 922.

window.registerShortcut, createShortcutPanel, getAllShortcuts, unregisterShortcut,
clearWindowShortcuts, the panel registry, and BOTH global keydown dispatchers are bare TOP-LEVEL
STATEMENTS at app.js's top level. A call-graph scan sees NONE of them.

That blind spot has now cost three times:
  * it nearly shipped a dead library A-Z rail (#896) — 43 of library.js's exports were
    referenced only from app.js's window contract;
  * it threw "Assignment to constant variable" in the session carve (#921), where the autoplay
    gate's top-level statements wrote state that had just become a read-only import;
  * and here it under-reported the slice by 3x.

The extractor takes them by construction now — any top-level statement that TOUCHES a moved
binding comes along — and the SEED is closed to a FIXED POINT, because those statements have
their own dependencies (_modifiersMatch, _isShortcutActive, _handleLibArrowNav, _gridColumns…)
that the declaration closure never walked. Seed -> pull the statements -> the statements need
more names -> re-seed. Iterate until it stops growing.

━━━ syncLibrarySong GOES ACROSS THE SEAM, NOT THROUGH AN IMPORT ━━━

The library arrow-nav calls it on Enter. It cannot be imported: syncLibrarySong reaches
showScreen/playSong, and a module importing app.js closes a cycle. It is the ONE name here that
had to stay behind, so it comes across the host seam — which is exactly what the seam is for.
host.js throws loudly if the wiring is ever dropped, and tests/js/host_contract.test.js fails in
CI if the hook drifts.

VERIFIED. A/B against origin/main in two browsers, IDENTICAL, zero page errors — and driven for
real, not merely present: the plugin API (register / unregister / getAll / panels), THE GLOBAL
KEYDOWN DISPATCHER actually firing a registered shortcut, that same shortcut correctly SUPPRESSED
while typing in a text input, and `?` opening the help modal.

545e569ad6 refactor(app): carve the song session out of app.js — playSong, showScreen, closeCurrentSong (R3d) (#921)
36 declarations + the 4 autoplay/auto-exit gate statements. 359 lines.
app.js 3,772 -> 3,242. Bodies VERBATIM.

━━━ THIS WAS "THE UNCUTTABLE HEART", AND IT IS 359 LINES ━━━

At the start of this epic, seeding a dependency closure from count-in, from loops, from
section-practice, or from the JUCE seek shim all returned the SAME 178-function, 3,360-line set.
playSong and showScreen called each other; everything called them; nothing could be cut anywhere.
The conclusion — correct at the time — was that NO closure-based carve could touch it at any
seed, and the answer was a host seam.

That was true THEN. Every slice taken out since (transport, loops, count-in, section-practice,
the library, the edit modal, settings) removed edges, and the strongly-connected component
DISSOLVED. This closure is 36 declarations with an interface width of FOUR.

The lesson is not that the seam was wrong — the seam is what MADE this possible, by letting the
carves proceed against a cyclic core instead of stalling on it. The lesson is to RE-MEASURE. An
SCC is a fact about a graph at a moment, not a property of the code.

━━━ THE BUG NO SCAN COULD SEE, AND THE A/B DID ━━━

First cut passed every gate — no-undef clean, no-cycle clean, 1045/1045, pytest green — and
THREW IN THE BROWSER: "Assignment to constant variable."

window.feedBack.holdAutoplay / holdAutoExit and their two event handlers are TOP-LEVEL
STATEMENTS, not declarations. They WRITE this cluster's state (_autoplayHeld, _autoExitTimer, …),
and an imported binding is READ-ONLY — so left behind in app.js, every one threw the instant the
module existed.

A dependency scan that walks DECLARATIONS cannot see them. Mine didn't. This is the same blind
spot that nearly shipped a dead library A-Z rail (#896): app.js keeps its public API in top-level
statements, and a call-graph is blind to every one of them.

The extractor now finds them by construction — any top-level statement that WRITES a moved
binding comes with the carve — and the gate statements live beside the machinery they drive,
which is where they belonged anyway.

━━━ ZERO OUTSIDE WRITES, BY MOVING THE BOUNDARY RATHER THAN BUILDING MACHINERY ━━━

The autoplay scalars and the wake-lock state were written from outside the cluster, which would
have forced a setter or a state container. But the writers — _releaseAutoplay, _acquireWakeLock —
plainly belong here. Pulling them in left ZERO outside writes, so every export is a plain import.
Same move as settings (#920): measure the writers before you reach for a container.

VERIFIED. A/B against origin/main in two browsers, IDENTICAL, zero page errors — including the
autoplay gate driven end to end: a plugin HOLDS autoplay, the song loads but does not start, the
RELEASE fires it, and a stale release is a no-op. That is the exact machinery that was throwing.

84fe29688c refactor(app): carve settings into static/js/settings.js (R3d) (#920)
22 declarations, 446 lines. app.js 4,218 -> 3,772. Bodies VERBATIM.

Settings load/save, the AV-offset nudge, the default-arrangement pin, the instrument pathway,
and the app-update channel.

━━━ INTERFACE WIDTH 1, AND IT GOT THERE BY DRAWING THE BOUNDARY IN THE RIGHT PLACE ━━━

app.js calls loadSettings() and nothing else.

The first cut was NOT clean: _defaultArrangement was written from OUTSIDE the cluster, and an
imported binding is READ-ONLY, so that one write would have forced a setter or a state
container — as it did for the player (player-state.js) and the library (library-state.js).

But the writers were saveSettings and pinCurrentArrangementDefault, which ARE settings
functions. Widening the slice to include them left ZERO outside writes. Every export is now a
plain read-only import and no container is needed.

Worth naming, because I reached for a container twice before: the fix for "this binding is
written from outside" is sometimes a container, and sometimes it just means the boundary is in
the wrong place. Measure the writers before you build machinery.

━━━ handleSliderInput STAYS A HOST HOOK, DELIBERATELY ━━━

It lives in settings now (it is a settings control), but player-controls.js must NOT import it:
this module already imports player-controls (_applyMastery, _autoplayExitEnabled, …), so a
direct back-import would close a cycle. player-controls keeps reading it through the host seam,
and app.js — the root, which imports both — wires it. That is exactly what the seam is for, and
the contract test proves the wiring survived.

VERIFIED. A/B against origin/main in two browsers: the window contract, the settings screen
rendering, the AV-offset and default-arrangement controls present, and a real `input` event
dispatched on a slider — which is the path that goes through the host seam. IDENTICAL, zero
page errors.

69aac32278 refactor(app): carve the edit-song modal into static/js/edit-modal.js (R3d) (#919)
4 functions, 234 lines. app.js 4,452 -> 4,218. Bodies VERBATIM.

INTERFACE WIDTH ZERO — nothing in app.js calls into this cluster. app.js needs only the names
on the window contract, so the markup's onclick= handlers resolve. That is what makes it the
cleanest slice left.

AND IT ONLY BECAME CLEAN BECAUSE THE LIBRARY CAME OUT FIRST (#896). Every dependency the modal
has is a module now: it reads six bindings out of ./library.js (loadLibrary, loadFavorites,
loadTreeView, _removeLibCardsForFilename, libView, _lastLibSelected) plus dom.js and the L
container. Before that carve, extracting this would have dragged the whole library with it.

Checked, and it matters: the modal never WRITES any of those six. An imported binding is
READ-ONLY, so a single write would have forced a setter or a state container. Every use is a
read, so plain imports suffice.

Acyclic: edit-modal -> { dom, library-state, library }, and library imports none of them back.

VERIFIED. A/B against origin/main in two browsers: the window contract, the modal actually
OPENING off a real library row, its title and year fields rendering, and the data-edit-save
wiring (rather than an inline onclick embedding the filename — the fix this cluster's harness
exists to guard). IDENTICAL, no new page errors.
