Live-app fix (Place Footprints / routing dead in Chrome): submodule
bumps carry the coroutine ownership fix (kicad 012d95ecb4) and the
handler-exception survival fix (wxwidgets 1b5f0e31f4).
Emscripten-6 fallout:
- occ/ngspice worker wrappers: mainScriptUrlOrBlob was removed
upstream; pthread children re-run the wrapper blob, so an em-pthread
realm now importScripts the glue and gets out of the way (before:
recursive service boots, pool never fills, silent 180s boot hangs —
every occ spec and ngspice bg_run).
- Makefile.wasm: -sASYNCIFY frankenlinks on the no-wx coroutine repro
targets ported to -sJSPI (the JSPI-only libcontext crashed at first
yield under them); mainloop/gl repro pages drive their tick through a
promising export (emscripten_set_main_loop callbacks cannot suspend);
retired inject-dyncall-shims lines removed (targets were unbuildable
since Phase 8); $stringToNewUTF8 force-included (the EM_ASM value
bridge aborted the runtime on the first decoded exception).
- fiber-park levers: neither embind shape can drive suspending levers
(plain throws on strict-JSPI Firefox; emscripten::async() re-executes
its invoker on settle) — kept sync for manual Chromium probing, spec
coverage moved to the jspi-coroutine harness (18 cases).
Suite work:
- Playwright 1.61.1 -> 1.62.1 (Firefox 153: JSPI on by default).
- fiber-resume-park.spec retired -> coroutine-lifecycle.spec: census
gate over boot / board load / chooser open / cancel (deterministically
red on the pre-fix build).
- Blind asyncify-era pins re-keyed: quasimodal-strand + wait-beacons
beacon regexes, footprint-chooser-close liveness -> wx parking-timer
heartbeat (scheduler counters idle flat on Firefox).
- occ/ngspice test providers: 60s boot timeout + worker error
surfacing (a worker death used to be a silent 180s timeout).
- Harness pages: stale 9.99 config dir -> 10.0 (library_manager wxCHECK
noise, chooser had no libraries).
- gal-webgl harness: missing artifacts rebuilt (boost/glm extracted to
the host sysroot), PgmOrNull stub added for the rebased GAL.
- jspi-scheduler: clean-shutdown console line restored (app-quit
contract), quarantine never yanks SP from a live window.
Gates: test:e2e 699 passed / 0 failed (wx-chromium, kicad-firefox,
kicad-chromium, jspi-firefox, coroutine-firefox); web ff/cr/mobile 71
passed; lint:ci-coverage 166, lint:determinism 163, screenshots
manifest 492 current, corpus 7/7, tools:contract green. Offline
screenshot baselines show expected mass drift from the engine bump —
re-baseline (screenshots:noise -> promote) is a follow-up.

Phase 8 in the parent repo. Deleted: asyncify-scheduler.js, apply-asyncify.sh,
apply-finalize.sh, inject-dyncall-shims.sh, asyncify-imports/removelist.txt,
the wasm-opt/finalize stub pair, scripts/binaryen-hoist-pass/ (the fork stays
a dormant submodule; removal is a follow-up), bench/wasm-opt-bench.sh (README
marked historical), wasm/shims/context_sleep.cpp, and the sched-context
harness app + Makefile targets.
PCBJAM_ASYNC_BACKEND is gone: build-wx-wasm.sh hardcodes the jspi stamp
(still force-cleans pre-migration trees), build-kicad-target.sh gives editors
the JSPI link surface and the CLIs nothing (they pin ASYNCIFY=0), the stub
dance is replaced by an unconditional .real-restore, build-wasm-test.sh lost
its whole post-link loop, docker/build.sh's postprocess is the ENV shim only,
and Makefile.wasm links every app JSPI with the scheduler shim as a tracked
prerequisite. pcbjam_async_policy.h keys on __EMSCRIPTEN__.
jspi-scheduler.js: wxWasmMainLoopPump dropped from the wrap census (the
export died with the D5 detach); inert [TRACE] instrumentation removed.
CI: wasm-build.yml rewritten for the single-cache pipeline (one output cache
keyed on compile inputs; post-processed bytes cached after the shim);
opt_level input removed from both callers. wasm-cache-hash.mjs inputs now
cover patch-env-shim.mjs + jspi-scheduler.js + jspi-exports.txt.

wasm/shims/context_sleep.cpp: a main-thread nanosleep whose frame stands on a
scheduler context that OWNS the stack arms a mailbox wake and yield_parks that
context instead of suspending the stack in place. It lives in the sleep
primitive rather than in tool_manager.cpp on purpose - KiCad and the wx core
stay untouched (CLAUDE.md's fork rule) and the whole K7 class moves at once,
not just TOOL_MANAGER::RunSynchronousAction's spin loop.
MEASURED AT D-ON, and it is NOT what unblocks Phase D. The four canvas-tool
specs still fail, but the trace now names a different cause: the fatal swap is
old=<libcontext ROOT> new=<tool coroutine> with mouseEventHandlerFunc above it
- a DOM mouse handler entering wasm DIRECTLY on the main stack, bypassing the
tick. So one coroutine is entered two ways: by the tick through the dispatch
context as a STAR TRANSFER, and by DOM handlers as a DIRECT SYMMETRIC SWAP. A
capture written by one path cannot be rewound by the other -> index out of
bounds in doRewind. That is section 7 rule 5 (partial migration is worse than
none) in its purest measured form, and it is why the harness stays green: its
coroutines are only ever entered from one place.
So the next increment is the DOM event entries (mouse/key/wheel/resize must
hand their events to the dispatch context as the tick does), not another park
site. It subsumes the one-root work too: with no dispatch on the main stack,
resolve_root_identity() always answers "the running context".
Landing state: STAR_DISPATCH=0, kicad 139 passed / 1 (pre-existing occ-probe)
= baseline, with the sleep shim in and inert.

Phase B increment recorded in §10. The wx battery is GREEN at D-on (395/1,
the 1 pre-existing) with dispatch contexts, context waits and star transfers
all live - the first clean battery of the migration. Gaps 1 and 2 from the
D-on probe are closed (terminal coroutine finish; wake/refusal semantics),
and a third containment was found and added: an exception escaping a handler
propagates out through drain()'s fiber swap and would otherwise leave the
registry mid-transition, dead-pumping every later wait. Shim carries the new
abandon call; .ci-cache-epoch -> 12.
THE BOUNDARY: on the full KiCad suite D-on loses four canvas-tool specs
(draw-wires, draw-lines, move-with-m, presence-locks move) to `index out of
bounds` in doRewind - the blue screen itself. Real tool coroutines park IN
PLACE inside their bodies, and a star transfer over an already-parked stack
rewinds state the fiber layer cannot see; the harness's coroutines yield
cleanly, so it goes green while KiCad does not (the doc-19 lesson again:
the harness models the shape, not the parks). So D cannot carry KiCad until
the tool-body park sites are contexts too - C+E completion, which §5 already
ordered before the flip. This measurement makes that ordering non-negotiable.
Landing state verified: STAR_DISPATCH=0, kicad 139 passed / 1 (pre-existing
occ-probe glb) = the Phase A baseline exactly, wx battery 395/1.

NOT GREEN. resolveWait marks a context-parked waiter ready and arms a pump
instead of resolving a promise nobody awaits.
The doc records the measured correction: DoRun parks the MAIN stack every
frame in wxWasmYieldToBrowser, which doc 21 called safe-by-construction only
because dispatch also ran there. With the scheduler swapping contexts from the
tick, those interleave over one currData - overlapped-wake, the exact class
this work exists to remove. So the main loop must become a context (D5) and
the bridges (E) join the same flip: D5+D+C+B+E land together.

Post-gate scrubs: vestigial 'startModal' removed from ASYNCIFY_IMPORTS

SHIM_DISABLE_HANDLESLEEP ablation skip, and the
SHIM_DISABLE_TRAMPOLINE_HEAL ablation skip are gone, and
scripts/common/shims/handlesleep.js is deleted (the scheduler subsumed

The editor reported nothing when a session died. Evidence lived only in-tab —
an 800-line React array behind a "Show console" button — so diagnosis meant
asking a user to paste a screenshot.
Better Stack's Error Tracking ingests the Sentry wire protocol, so this runs
the stock @sentry/browser against a Better Stack DSN. Sentry.init installs its
own window error/unhandledrejection handlers, so uncaught main-thread errors
and the wasm traps that escape emscripten's DOM event handlers are captured
with no instrumentation at the throw sites. Not their JS tag: it has no
beforeSend or fingerprint hooks, its runtime spawns workers from cross-origin
CDN hosts (this page is COEP: require-corp), and it ships session replay on by
default — which on a CAD canvas records customers' board geometry.
@sentry/browser is imported in exactly one file so the vendor stays swappable,
mirroring how lib/analytics.ts isolates Plausible.
Also replaces the terminal-signature regex with a shared, unit-tested predicate
(wasm/terminal-error.ts) used by BOTH the fatal overlay and the reporter, so
they cannot disagree. The regex was a type check written as a string match and
had three live holes: `RuntimeError` was listed but never appears IN
`.message`; Chrome's bare "unreachable" and "null function" matched nothing
(the v0.1.20 prod log is exactly those); and narrowing "table index is out of
bounds" to `\bindex out of bounds` for Firefox in 197f317 silently stopped
matching Chrome's spelling. Checking the TYPE — every trap in this family is a
WebAssembly.RuntimeError — covers all engines and ends the spelling chase; the
message patterns remain as a fallback for paths that lose the Error object,
such as a worker ErrorEvent crossing the realm boundary with error: null.
197f317's pthread-worker tap, promote() and Firefox findings are kept as-is.
Notes:
- Off unless VITE_ERRORS_DSN is set AND VITE_ALLOW_USER_OVERRIDE !== "1" (dev
servers and every Playwright harness set the latter, and production builds
never do), so a production DSN in a local .env still cannot report. With no
DSN the whole SDK is const-folded out: 1,193,080 vs 1,282,463 bytes of JS.
- browserApiErrors integration removed. It wraps setTimeout/rAF/addEventListener
in try/catch, which is exactly how KiCad-on-Emscripten drives its main loop.
- Console breadcrumbs off (collab/debug.ts's clog fires per Yjs update and would
evict the ring before any crash); dom/fetch/navigation breadcrumbs kept.
- beforeSend redacts token/apiKey/Bearer — collab/provider.ts puts the collab
token in the y-partyserver URL, so a connection-failure string carries a live
credential — and guards the cascade: one wedge produced 8 errors in prod, and
after the first terminal event the rest are dropped into cascade_count.
Verified end to end against the real EU host from a cross-origin-isolated page:
POST /api/<id>/envelope/ -> 200, and 4 terminal throws produce 1 event
(control: 1 throw, same count).
Privacy policy 9, cookie policy 6 and the licenses page are updated: Better
Stack is disclosed as an EU processor, and the licenses page now describes the
browser app's own JS dependencies, which it never did.

Every repo moved from emergence-engineering/ to PCBJam/, but the published
source pointers still named the old org. GitHub's transfer redirect resolves
them (all six checked, 301 -> 200), so nothing is broken today — but it stops
working the moment anyone creates a repo at an old path, and a GPLv3
corresponding-source pointer is a poor thing to leave depending on a redirect.
CI never passes --repo, so the hardcoded default is what actually ships: the
editor's version badge on editor.pcbjam.com has been linking users to the old
org for their source.
Covers the source pointers (licenses.md, terms.md 12.4, REPO_URL and its doc
comment, the three build-script --repo defaults, the site footer's build-commit
link) and the two "our GitHub" org links. Bumps the pcbjam-shared pointer for
the same fix there.
Deliberately untouched: emergence-engineering.com, the company domain behind
contact@ and the EE credit block — the trailing slash in the substitution keeps
it out. And docs/security-audit-glm/, which describes a finding rather than
linking anywhere.

The prod differential ladder finished: staged byte VOLUME on a warm load is
the only trigger left (V1a siblings-without-lib-tables dies, V1b +120 files
survives, V1c sibling KiCad files renamed byte-for-byte dies, V1d Leonardo +
123MB of inert markdown dies on loads 3-4; 14MB never dies). 3D models,
collab/ydoc/presence, lib tables, sibling KiCad handling and file count are
all exonerated — volume only loads the dice on the underlying race.
That made the crash reproducible locally for the first time in six campaigns:
a persistent browser profile + a 110MB project fails every warm load with the
exact prod signature. Iteration is now ~12 minutes instead of a release cycle.
Shim: every fiber switch now records the departing side's remaining asyncify
buffer and its recorded rewind entry (rem=/rf=), which is what identified the
unrewindable capture and disproved buffer overflow. The deferral family is
closed for good — a microtask-deferred retry on a clean empty stack died
identically to the nested rewind, because the suspension is broken at write
time, not by nesting.
Shell: log the origin stack when wx reports the top window destroyed. That
notification fires from ~wxTopLevelWindowWasm for ANY top-level window, so a
transient frame dying mid-load navigates the user out of the editor — a real
bug in its own right, found while chasing the empty flight-recorder dumps.

The 96-event recorder ring holds under a second of history at idle tick rate
(~110Hz), so settle-time collision pressure scrolls out before any poll can
read it — the prod dumps only caught the kill because the trap froze the
moment. Scroll-proof totals since boot: every finishContextSwitch increments
fcsTotal; every root entry inside a sleep-wake window increments rootHotTotal
(the fatal precondition). Both appear in the [wx-asyncify] STATE line, i.e.
in every trap auto-dump, every __wxAsyncifyDump() call, and every blue-screen
console — turning ANY prod load (crashing or clean) into a dose measurement
for the differential-repro experiment (which project ingredient generates
collision windows: siblings, 3D models, libs).

v0.1.24 in prod, doubly convicted the same morning: the Leonardo open
crawled/hung (open:settled result=failed at the 60s escape, heap never past
256MB — every main-loop iteration runs INSIDE its yield-wake extent, so the
"root-owned wake" scope matched thousands of legitimate nested coroutine
Call/returns per open, each paying a deferred macrotask, throttled to ≥1s in
a background tab), AND the Nano crashed 22ms after deferrals=1 fired.
Harmful and insufficient: the fatal nested-rewind interleave and the benign
bulk are observationally identical at this layer — no discriminator exists.
Retired (second and final retraction, async/16 round 5). What stays shipped
and clean: consume-once root suspensions, the internally-parked quarantine +
laundering check, the flight recorder + beacons, the WSOD floor, the
pendingSleeps leak fix (confirmed by pendingSleeps=[] in the Nano dump). The
rare nested-rewind crash is ACCEPTED and fully observable until the
structural fix — the design-B fiber-first runtime (async/06,12,13), where
one scheduler owns every suspension and this interleave cannot exist.

The v0.1.23 flight recorder caught the kill live (console-export-2026-8-1_19-16-8):
dozens of benign fiber round-trips at w=0, the yield cycling healthily on its
buffer — then "fcs … ROOT w=1" and the trap, state frozen at Rewinding with
currData=root+20. The fatal condition, observed rather than inferred: a fiber
round-trip inside the ROOT's OWN sleep-wake continuation re-suspends and
re-rewinds the root nested inside its live wake rewind. Consume-once passed
correctly — it guards a different corruption and stays.
The round-3 deferral was aimed right but unscoped (taxed fiber-owned wakes,
flaked S4). Final form: every fresh sleep is tagged root- or fiber-owned
(fiber ⇔ started inside a finishContextSwitch fiber slice or a fiber-owned
wake; root entries don't count as slices); finishContextSwitch(root) defers
one macrotask ONLY while a root-owned wake is live (Asyncify.__wakingRoot).
Beacon: root-entry-deferred. Verified inert where it must be: zero beacons
across all 13 drift-trio-scenarios logs (26/26 + 25/26-then-26/26 stress —
the single miss carried no beacons, i.e. the pre-existing under-load flake).
Also: resume re-entries no longer push sleep contexts (the v0.1.23 dump
carried ~380 leaked zero-linked entries), and wake events in the recorder are
tagged R/f for ownership.

The deferral (9ca2ac1) modeled the wrong condition and taxed every parked
fiber completion with a macrotask hop: under CI load that stretched
three-client apply chains and flaked drift-trio S4 twice consecutively
(26/26 green locally under stress) — retracted.
The actual fatal state, readable in all four prod stacks once seen: a SECOND
rewind of the same root suspension. Root suspends once per fiber_swap out of
it; two parked fibers completing against one root suspension epoch (a tool
fiber + a collab fiber both waking around open:settled) each drive
finishContextSwitch(root) — the second rewinds already-consumed data →
"unreachable executed" → poisoned runtime, with the wake-side "index out of
bounds" as the sibling symptom.
Cure: stop exempting root from the validity check the shim already keeps.
First consumption proceeds synchronously — zero added latency anywhere; the
second is refused ([wx-asyncify] "root suspension already consumed") — the
yielded fiber stays properly suspended and resumable, root continues via its
real pending resume, libcontext's ghost-epoch contract enforced one layer
lower. Root remains exempt only from the internally-parked quarantine (its
yield park is routine).

v0.1.22 still trapped with BOTH guards silent: the fatal rewind's target is
the ROOT context, which layer 2 exempted. All four prod stacks are the same
collision — a fiber completes its yield-back to main while main's sleep-wake
rewind is still on the stack (maybeStopUnwind → trampoline →
finishContextSwitch → doRewind(root) → unreachable), two "resume main" paths
interleaved in one tick; the 8ms-earlier "index out of bounds" is the wake
side of the same event.
Root entry is legal and constant in healthy flow; only the wake-window
overlap is fatal. So: serialize, don't refuse. The shim marks the
synchronous wake window (Asyncify.__inSleepWake around wakeUp) and DEFERS a
root finishContextSwitch landing inside it by one macrotask
([wx-asyncify] root-entry-deferred beacon, trampoline retry) — an ordering
change only, nothing dropped. Suspension recording happens before the
deferral branch, so the yielding fiber's validity survives the wake chain
nulling currData.
Plus a flight recorder: a 96-entry ring of asyncify/fiber events (sleeps,
wakes, every context switch with ROOT/wake-depth, refusals, deferrals),
silent in normal operation, auto-dumped with full machine state next to the
first trap signature in the console; window.__wxAsyncifyDump() on demand.
The next prod export reads like a black box, not a stack-shape puzzle.

v0.1.21 still trapped with ZERO jump-refused beacons: the fatal swap PASSED
the C++ swap_suspended guard. Mechanism (async/16 round 2): a fresh JS entry
executing while g_current_context still points at a parked fiber gets
attributed to that fiber — fiber_swap writes a fresh, valid-LOOKING foreign
suspension into the parked fiber's struct and re-marks the flag. The flag
lies; the resume rewinds garbage.
This guard tracks truth at the emscripten-fiber layer (handlesleep.js wraps
Fibers.finishContextSwitch):
- valid suspensions = real swap-outs (currData == oldFiber+20 when the
trampoline runs), consumed on rewind;
- internally-parked = an entered slice that ended in a handleSleep park
(currData set, no nextFiber) — quarantined until a GENUINE swap-out,
where genuine means the fiber's pending sleep has resolved
(__pendingSleepContexts), so a laundering write cannot lift it;
- entering a quarantined or suspension-less fiber is REFUSED
([wx-asyncify] fiber-resume-refused, ghost contract).
The ROOT context is exempt from quarantine and refusal: its rewound
continuation runs the whole main loop, whose routine yield park says nothing
about a fiber body — the first build of this guard quarantined main off that
signal and starved every coroutine return (19 collab e2e reds, empty
results). Root = the old side of the first switch ever.

The shim has been silently restoring Asyncify.currData across overlapping
parks since it was written — so a prod console dump could never say whether
the #9153 family fired, mislinked, or was bypassed. Rate-limited [wx-asyncify]
reporting, calibrated against the timer-park e2e (2 rounds, 2026-07-31):
- concurrent-park: a FRESH park (state 0) starting while another chain's
currData is live. state-2 entries are NOT reported — every legal resume
re-enters handleSleep while Rewinding (~100/s measured on a healthy run).
- reentrant-state: handleSleep entered mid-unwind (state 1) — never observed;
if it ever fires it IS the bug.
- aliased-wake-live / overlapped-wake: the restore actually repairing —
dangerous (other chain still parked) vs benign (other chain done). The
e2e observed 8 live cross-restores in one run, all survived.
Console.log only, no printf plumbing needed; stacks name the parker

The v0.1.14.1 release gate died in "Build wxWidgets (wxUniversal WASM)" with
"No rule to make target 3rdparty/pcre/src/pcre2_chartables.c". Nothing in the
tree changed wx — the submodule is the same SHA that released fine as v0.1.13
— and the two main CI runs on this tree built wx and went on to run e2e. The
restored build-wasm/wxwidgets cache is the variable: pcre's makefile rm's that
path and re-links it to pcre2_chartables.c.dist at configure time, so a cache
captured around that window restores a tree whose pcre rule cannot be
satisfied from a clean checkout.
CI's wx cache key hashes scripts/build-wx-wasm.sh, so a header edit is the
lever that discards it. Documented as an explicit epoch counter there, since
the next person hitting this will not guess that editing a build script is how
you evict a cache.

Two consecutive publish-libs runs died on runner-side CF API flakiness (a 502
mid-put, then 'terminated' on the first probe). Gets and puts now retry with
backoff; a definitive missing-object error still returns null immediately.

A CF API 502 on the manifest.json probe made publish-libs misdetect an
already-published tag as unpublished and start a full republish (byte-identical
immutable content, so harmless — but ~30 min of redundant uploads before a
second 502 killed it). Only wrangler's definitive missing-object error now
reads as absent; anything else throws.

Cold loads on versioned CDN deploys now show a consent card (editor MB +
symbol/footprint lib figures, downloaded-now vs on-demand) and wait for OK
before any big fetch; warm loads skip it and show truthful stages (loading
from cache / Compiling / Starting KiCad) instead of the first-download line.
- wasm-assets: resolveWasmMeta (bundle/ver/sizes), download-completion marker
keyed by content-addressed bundle/ver, update wording, auto-download opt-out,
HEAD size fallback
- boot: manifest raw size as the progress total (fixes the br/gzip
Content-Length mismatch), marker written after download+instantiate succeed
- cdn-source: syncState() — IDB warmth peek + sizes.json cold sums
- synced-source: syncState() from the backend envelope's sync refs (private
platform); remote-source passes libSchema.sync through
- publish-wasm: manifest schema 2 with per-bundle sizes (registry-persisted,
reuse + snapshot modes); publish-libs: sizes.json sibling key + top-up mode
- fixed 4 stale unit tests (bundle mapping, session-identity email)

brotli q11 over the ~320MB wasm set ran serially on one core (~0.4MB/s),
dominating the release publish job. Compress every to-be-uploaded file
concurrently on the libuv threadpool (compressBytesAsync + UV_THREADPOOL_SIZE
sized to the machine), so wall time drops from sum-of-files to roughly the
largest single file (kicad_editor.wasm): 329s for the full set locally vs
~11.5min of CPU. Upload ordering invariants unchanged: meta.json still last
per tool, registry last overall; moved-tag guard and reuse path untouched.
Also adds BROTLI_PARAM_SIZE_HINT and moves the publish-wasm job to
ubicloud-standard-8 so there is a core per file.
Verified byte-identical CDN layout vs the old script (local driver, pinned
builtAt), blob roundtrip to source sha, reuse + --from-registry modes.

Redirects from emergence-engineering still work, but fresh clones and CI
checkouts should reference the real home.

Vercel was doing the apex->www 308 itself (its "redirect to www" project
setting), so nothing about Cloudflare requires a redirect — the behaviour
just disappears with Vercel. Rather than rebuild it with a zone Redirect
Rule plus a proxied placeholder record, attach pcbjam.com as a SECOND
custom domain on pcbjam-site. Both hosts serve the site and the pages
already emit canonical=www, which is what consolidates them for search.
That drops the riskiest artefact in the migration. Redirect Rules are
zone-scoped and run BEFORE Workers/Pages routing, so a `contains` match
instead of `eq` would 308 app./editor./demo./api. to www — breaking the
product API, not just a marketing page. The sibling hosts are also the
reason this was worth avoiding rather than merely guarding.
APEX_MODE (lib/common.sh) selects the topology, defaulting to `serve`.
08-verify-prod.sh now dispatches through assert_apex: in serve mode it
requires the apex to answer 200 with no hop, to not be a stale Vercel
response, to declare canonical=www, and to expose /api/waitlist. The
`redirect` mode and 07's rules/apex phases are kept for the alternative.
08 also checks the attached domains via wrangler rather than the REST API,
so the whole serve-mode path needs only `wrangler login` — no zone scopes
at all.
Comments that explained themselves via the old redirect are corrected:
astro.config.mjs, web/standalone/src/lib/config.ts and
scripts/deploy/build-demo.mjs. The demo keeps posting to www — not because
the apex redirects, but because a CORS preflight cannot follow one, so
aiming at a host that might ever redirect is a latent breakage.

Two generic (manufacturer-agnostic) pcbnew-side subcommands for platform
manufacturing plugins: --ipc356 (IPC-D-356 netlist via IPC356D_WRITER) and
--fab-components (board metrics + per-footprint placement/BOM JSON —
absolute board coords, consumers apply their own conventions). Bumps the
kicad submodule for the diet keep-back of export_d356.cpp.
Also closes a CI cache gap: wasm-cache-hash never hashed wasm/**, so a
pure wasm/cli change would cache-hit stale output — { dir: "wasm" } is
now an input (busts the cache once on landing).

VITE_APP_URL (build-editor --app-base, set to app.pcbjam.com in release CI)
turns on a redirect gate in App: home, project overview and mgmt-only paths
bounce to the mgmt app preserving path+search; tool boots, file deep-links,
lib editors and the @local pseudo-scope stay local. Unset (dev/demo) keeps
today's behavior. Policy is a pure helper (lib/redirect.ts) + vitest table.

The wasm-opt bench VM cloud-init seed carried a committed console/SSH password
and enabled SSH password auth. setup-vm.sh already requires and injects an SSH
pubkey, so lock the password (lock_passwd: true) and disable SSH password auth
(ssh_pwauth: false).

All pcbjam properties now load the same new-format Plausible script
(https://plausible.io/js/pa-KjNS9YmidydULZTstsjRg.js — one dashboard,
segment by hostname) instead of per-domain data-domain sites:
- site: replace Vercel Analytics with the pa- snippet in BaseLayout
(is:inline, prod-only, crossorigin="anonymous" for the COEP
require-corp routes in vercel.json); drop @vercel/analytics dep.
Legal pages (cookies/privacy) rewritten Vercel -> Plausible.
- standalone: initAnalytics() rewritten for the new script format
(queue shim + plausible.init(), async, no data-domain). The gate is
now VITE_PLAUSIBLE_SRC (script URL, deploy-time opt-in) — unset means
no tracking, so dev checkouts and third-party GPL builds stay clean.
VITE_PLAUSIBLE_DOMAIN is gone.
- deploy: build-demo/build-editor --plausible now takes the script URL;
release.yml/deploy-demo.yml hardcode the (public) pa- URL, so the
repo Actions variable PLAUSIBLE_DOMAIN is no longer used.
Verified: standalone tsc + vite build (pa- URL present with env, absent
without, crossOrigin kept); astro build has the snippet on all layout
pages and no vercel/insights references; astro dev stays untracked.

New wasm/cli/sym_convert_stubs.cpp: first-definition-wins overrides
(--allow-multiple-definition) severing schematic load/save, the KIFONT
factory (drops newstroke + freetype/harfbuzz), and the four UI virtuals
whose bodies reference pruned typeinfo/data. New
wasm/bindings/sym_convert_embind.cpp: no-op kicadCollabOnSave so the
converter stops linking eeschema's embind object (and --bind) that rooted
the editor surface from .init_array. build-kicad-target.sh: per-app
EMBIND_LINK_FLAG + sym_convert now uses its own embind TU. Bumps kicad
(kiface prune, gated). Output byte-identical on the qa corpus.

New release.yml job `deploy-editor` (parallel to deploy-demo, same per-tag
WASM manifest): builds the standalone in REMOTE mode via the new
scripts/deploy/build-editor.mjs — projects/libs/auth from the closed API
(VITE_API_BASE_URL=https://api.pcbjam.com, VITE_LIBS_SOURCE=synced), Yjs
board rooms through the API host's path route (VITE_YJS_ENDPOINT=api origin,
doc source ydoc) — and ships it to the pcbjam-editor Pages project. The
demo deploy is unchanged. The closed stack itself (api./app.pcbjam.com)
deploys from pcbjam-private; when both sides change, that repo tags first.

The merged kicad_editor bundle made the chooser's footprint side reachable
from a schematic session; this wires up the data:
- boot.ts/constants.ts: every kicad_editor frame seeds BOTH sym-lib-table and
fp-lib-table (+ placeholder files; a created user lib joins both lists) —
the eeschema frame used to write fp-lib-table empty, leaving the selector
dead. TOOL_LIB_KIND remains only the presync/primary-kind lever.
- publish-libs.ts + kicad-pretty.ts: publish fp-index.json per tag —
[name, uniquePadCount] per footprint (countUniquePads mirrors KiCad's
GetUniquePadCount(DO_NOT_INCLUDE_NPTH)); index-only top-up mode for
already-published immutable tags.
- source.ts/cdn-source.ts: new bridge op "index" (source-global, dispatched
before the lib-id parse) + LibsSource.getFpIndex; the CDN source fetches
<tag>/fp-index.json once (404 ⇒ null ⇒ C++ default-only fallback).
- dev-demo.mjs: --libs-local serves a local publish-libs layout same-origin
at /libs-cdn (mirrors --models-local).
- tests/web/eeschema-fp-selector.spec.ts: e2e — chooser opens in --frame=sch,
selector fills from ONE index crossing, clicking a row per-item-gets the
body and the cross-face GAL preview renders; adaptive for index-less
sources (asserts crash-free default-only selector).
Submodule bumps: kicad (index-backed filterFootprints + preview AsyncLoad
fix + modal-pump crash guard), wxwidgets (modal pump logs e.stack).
