Jinwoo Hong 9641a1b544 feat(mobile-web-bundle): serve the packaged mobile web bundle over RPC (OTA phase A, 3/5) (#21348)
* feat(mobile-web-bundle): serve the bundle manifest and chunks over RPC

Two paired-runtime methods on the already-authenticated connection:
`mobileWeb.bundle.manifest` returns this install's manifest plus the chunk
size it advertises, and `mobileWeb.bundle.chunk` returns one aligned range of
one asset with the whole asset's length and hash, so a single chunk describes
what it belongs to.

`path` is accepted only by exact match against a manifest member, so traversal
is unreachable rather than mitigated. Each asset's on-disk sha256 is verified
once and the verdict remembered, concurrent first readers sharing one hash.
Reads are capped at four in flight per connection, and a disconnected client
stops costing reads at the next checkpoint.

No SSH or relay proxying: a runtime answers only out of its own install.

* test(mobile-web-bundle): pin the three buildId serializers against each other

The canonical serialization exists in the builder, the packaging guard, and the
shared contract, because the two packaging scripts run on bare node before any
build output exists and cannot import TypeScript. A divergence in any one would
reject every honest bundle at packaging, or ship a bundle whose id the phone
recomputes differently and re-downloads forever. Proved red by swapping the
guard's code-unit sort for localeCompare: five of six cases fail.

Exports the guard's serializer for the test; no packaging behaviour changes.

* test(mobile-web-bundle): cover every error code and a multi-chunk paging round trip

Against a synthetic bundle in a temp dir, because the real builder's largest
asset is under one chunk and CI unit jobs never build out/mobile-web. The
fixture's script spans three chunks, its stylesheet is exactly one, and one
asset is empty, so paging, the eof boundary, and the zero-byte case are
exercised rather than assumed.

Reads in flight are held by latching `open`, so the four-per-connection cap and
an abort arriving mid-read are deterministic rather than a race with a
stopwatch. Both were proved red: dropping the abort check after verification
fails the abort case, and keying the cap on connectionId alone fails the
device-token case.

* fix(mobile-web-bundle): resolve the bundle root through the AppEnvironment port

check:runtime-electron-ratchet caught this: the resolver sat beside
getBundledWebClientRoot in src/main/startup and imported electron, and importing
it from an RPC method pulled the first electron edge into a runtime graph whose
baseline is zero. The runtime has to stay bootable on plain Node.

So it reads app.getAppPath() through the port every other runtime module already
uses, and moves next to its two callers under src/main/runtime. A host with no
environment installed has no install root, which is the same answer as having no
bundle. orcad answers getAppPath from its own install root, so a headless
runtime that carries the artifact serves it with no special case.

* test(mobile-web-bundle): cover the resolver's two probe layouts directly

Also stops exporting the manifest filename, which nothing outside the resolver
needs.

* test(mobile-web-bundle): pin both methods on the mobile allowlist

The scanner only checks mobile-used ⊆ allowlist, and no mobile source calls these
until A5, so deleting both entries left every test green.

* fix(mobile-web-bundle): keep filesystem failures inside the six error codes

An asset unlinked or truncated after its verdict was cached reached the client as
runtime_error carrying the desktop's absolute install path. Both now answer
mobile_web_bundle_asset_changed, with the cause warned host-side only. A short
positional read is the truncation case, so it throws instead of paging the client
past the end.

* refactor(mobile-web-bundle): drop the unreachable release-idempotence guard

The one caller releases exactly once in a finally; removing the flag left every
test green, so it was defensiveness against a caller that does not exist.

* test(mobile-web-bundle): prove a failed verify is not cached as a verdict

The verdict cache never invalidates, so a transient read failure remembered as a
verdict would poison the asset for the life of the process. Removing the delete
left every test green until now.

* refactor(mobile-web-bundle): delete the unsatisfiable manifest params schema

The dispatcher substitutes `{}` for absent params, so `z.null()` could never
parse; the method declares `params: null` instead. A comment on the method name
records why there is no schema.

* fix(mobile-web-bundle): fill the read window instead of failing a partial read

fs.read may answer short of what it was asked for before EOF, so the previous
check turned a legitimate partial read into a spurious asset_changed. The loop
mirrors the relay's readFullStreamChunk, which is not imported because it sits
behind the relay dispatcher's module graph; only a read returning nothing is
treated as truncation.

* refactor(mobile-web-bundle): read the disconnect idiom with the shared predicate

isClientDisconnectedError already exports exactly the check the catch needed, so
the local error class goes away and the throw returns to the repo-wide idiom. The
module doc now says asContractError is a total catch.

* test(mobile-web-bundle): pin the four branches no test was holding

Each one survived a mutation: the abort check before verification, the
per-process manifest cache, the buildId component of the verdict key, and
delete-at-zero in the admission map. The last two matter beyond hygiene — a
verdict keyed by path alone carries a failed verdict onto the next build of
index.html, and a map that never drops a key retains one pairing token per
socket.

Jinwoo Hong ad4f26cdd4 feat(build): build, verify and package the mobile web bundle with every desktop release (OTA phase A, 2/5) (#21326)
* feat(mobile-web): add the Phase A bootstrap web source

A peer of src/ so the root workspace owns it and mobile's separate lockfile
stays out of packaging. Four assets across four content types, enough to
exercise multi-asset manifest handling rather than assume it.

The page reads buildId from manifest.json at runtime: buildId hashes the asset
list that index.html belongs to, so injecting it into a hashed asset would make
that asset's hash depend on itself.

Registered as a fourth typecheck project; without it the entry would be the
only TypeScript in a release path that tsc never sees.

* feat(build): build and verify the mobile web bundle from the root workspace

Root esbuild over mobile-web/ into out/mobile-web/, content-addressed as
assets/<sha256>.<ext> with index.html the only stable name. buildId is the
sha256 of the canonical serialization of the sorted asset list, so it is a pure
function of content and usable as a cache key with no further reasoning.

The verifier builds twice into scratch dirs and compares: a timestamp, an
absolute path, or an unstable ordering fails the build when someone introduces
it, not the first time a phone gets a spurious cache miss. It also enforces the
Phase A budget of 16 assets and 256 KiB, separate from the permanent contract
ceiling.

build:release does not call build:desktop, so build:mobile-web is wired into
build:desktop, build:release, and build:release:parallel.

* feat(packaging): fail the release when the mobile web bundle is missing or stale

electron-builder only warns about a missing input, so without a beforePack
guard a release ships an app that advertises the bundle capability and then
errors on every request. The hash check, not the existence check, is what
catches a half-written or stale out/.

The source tree is excluded from app.asar; out/mobile-web ships inside it under
the existing out rules, exactly as out/web does.

* refactor(mobile-web): narrow the manifest with `in` instead of a cast

The changed-code casting gate rejects assertions, and `in` narrows the same
untrusted JSON without one.

* fix(mobile-web): move the bundle source under src/ so the root guard passes

.github/scripts/check-root-directory-entries.mjs blocks any new top-level entry
by name, so mobile-web/ could not live at the root.

The source is excluded from app.asar by the existing '!src{,/**/*}' rule; the
explicit '!src/mobile-web{,/**/*}' entry stays as a marker. out/mobile-web is
unaffected and still ships under the out rules like out/web. No tsconfig
includes src/**, so node, web, cli, and relay do not pick the tree up; it is
registered as a knip entry so audit:dead-code does not call it unused.

buildId is unchanged at 9d78435e: the builder hashes content, not paths.

* fix(build): resolve the entry-script guard through pathToFileURL

`file://${process.argv[1]}` never equals import.meta.url on Windows, where that
url is file:///C:/... So the builder exited 0 having written nothing and the
Windows packaging job failed later, at the guard, with no clue why. Every other
script in config/scripts already uses pathToFileURL; this one now does too, via
an exported predicate a posix runner can exercise with a win32 path.

The verify script had no entry guard at all, so importing its budget constants
ran the whole verification — including its process.exit — inside the test
worker. It is now a function behind the same guard.

* fix(ci): build the mobile web bundle in the PR package job

That job assembles packaging inputs step by step instead of calling
build:release, so the new beforePack guard hard-failed it.

The census test added here is the oracle: it walks every workflow job that
invokes electron-builder without --prepackaged (which short-circuits doPack
before beforePack) and requires a bundle-producing script in the same job. It
goes red on exactly pr.yml's package job when this step is removed. Ten jobs
covered; the other nine already ran build:release, build:release:parallel, or
build:desktop.

* fix(mobile-web): pin source line endings, because CRLF changes the buildId

Every text byte under src/mobile-web is hashed into an asset digest and from
there into buildId, so a CRLF checkout produces a different bundle id for the
same commit: 91af2897 instead of 9d78435e. That would make a Windows-built
desktop disagree with a mac-built one about which bundle a phone has cached.

.gitattributes pins eol=lf for the text sources and -text for the PNG, matching
the four trees already pinned for byte-hashing. The verify script asserts no
source file carries a CR, so the build fails if the pin ever stops applying
rather than silently shipping a second bundle identity.

* fix(test): census packaging jobs over raw workflow text, not re-serialized YAML

yaml.stringify folds long lines, and in dev-channel-win-build.yml's build-win the
fold landed between `electron-builder` and `--config`, so a real packaging job was
invisible to the census: 11 jobs exist, the test saw 10. Slice each job's raw source
by its parsed boundaries instead, and pin the inventory so a new packaging workflow
has to be added here on purpose.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(build): assert the script chain the packaging census trusts

The census only checks that a packaging job invokes one of ten build scripts; that
those scripts still reach build:mobile-web was asserted nowhere, so a dropped link
would leave every job looking covered while packaging failed at beforePack. Resolve
each script for real, and pin pr.yml's hand-rolled step, since that job never calls
build:release.

* fix(build): realpath the entry path before the direct-invocation compare

Node resolves symlinks in import.meta.url but not in argv[1], so `node /tmp/...`
against a /private/tmp realpath compared two different strings: the builder and the
verifier exited 0 having written and checked nothing. Same silent-success shape as
the Windows file:// bug, so the fix sits next to it, with both seams injectable.

* style(mobile-web): format bootstrap.css with oxfmt

It was the only tracked CSS failing oxfmt --check. The buildId is unchanged at
9d78435e8bb73c3341f833c20aaefbd7bfdfc414b68dadf87c1689d86728fe33, because esbuild's
CSS minifier normalises the whitespace this touches before the asset is hashed.

* fix(packaging): reject bundle files the manifest does not list

The guard only walked the manifest, so a dropped assets/stale.js passed: assets are
content-addressed, nothing ever overwrites a stale copy, and it would ship inside
asar unreachable and unverified. Require every file under out/mobile-web to be the
manifest or a listed asset.

* fix(packaging): give beforePack an explicit mobile web bundle root

The bundle guard read the repo's out/mobile-web unconditionally, so the two
arch-aware packaging tests that call the real beforePack went red in the unit-test
job, which never runs build:mobile-web. beforePack now takes the bundle root as a
second parameter defaulting to out/mobile-web, which is what electron-builder gets,
and those tests build a real bundle into a temp dir instead. The guard is neither
skipped nor made tolerant of a missing bundle.

* fix(packaging): census sees script-wrapped packers; dev verify reuses the guard

The workflow census only matched a literal `electron-builder --config` line, so
daemon-relocation-spike's `pnpm run build:unpack` (which packs and runs beforePack) was
invisible to it. Jobs now count when any `pnpm run <script>` they invoke chains to
electron-builder without --prepackaged; the spike joins the pinned list (12 jobs).

verify-mobile-web-bundle.mjs re-implemented a weaker subset of the packaging guard
(no safe-path check, no buildId recompute). It now calls assertMobileWebBundleBuilt, so a
manifest edited after the build fails at `pnpm build:mobile-web` exactly as at beforePack.
