docs(agents): promote v1.0.8 release learnings

Record three confirmed v1.0.8 failure modes (expo prebuild native
regressions, npm 10/11 lockfile divergence, local EAS build
preconditions) and promote each into docs/releasing.md, a new
docs/development/dependencies.md, and the release-preflight script.

## Symptom
`expo prebuild --clean` during the SDK 54 to 56 upgrade (and the
@bacons/apple-targets 0.1 to 5.0 bump) silently regressed four checked-in
native invariants. Each regression was caught only by a release gate or by
manual diffing against the last shipped tag (3fc6f8a, v1.0.7), not by
prebuild itself.
## Reproduction
Run `expo prebuild --clean` in apps/mobile against the upgraded SDK and diff
the regenerated ios/ and android/ projects against the previously committed
projects.
## Cause
1. Widget identity: apple-targets 5.x derives PRODUCT_BUNDLE_IDENTIFIER from
the target folder name, changing com.sauci.app.LiveDrawWidget to
com.sauci.app.widget, and repointed CODE_SIGN_ENTITLEMENTS to the
gitignored ios/.targets/LiveDrawWidget/generated.entitlements.
2. Android manifest lost the tools:node="remove" attributes on
READ_MEDIA_IMAGES and READ_MEDIA_VIDEO, so the built AAB regained
Play-forbidden permissions (verified via bundletool dump on the rejected
build 50 AAB).
3. iOS Info.plist gained dev-launcher-only keys NSBonjourServices
(_expo._tcp), NSLocalNetworkUsageDescription, and RCTMetroPort.
4. android/gradle.properties reset to stock -Xmx2048m
-XX:MaxMetaspaceSize=512m, causing Metaspace OOM in kspReleaseKotlin/CMake
under RN 0.85.
Separately, a package absent from the new SDK's bundledNativeModules
(expo-av) has no compatible release and fails the iOS archive (EXAV.h
imports removed ExpoModulesCore headers).
## Remediation
Fixed by restoring widget identity and tracking
targets/widget/generated.entitlements with a pinned bundleIdentifier
(604eec3); restoring manifest tools:node="remove" attributes (7aca39a);
removing the dev-launcher-only Info.plist keys (6bd04a6); raising
gradle.properties memory to 4096m/1024m (79233f5); and migrating expo-av to
expo-video/expo-audio (b8cb2add).
Extend apps/mobile/scripts/release-preflight.mjs with executable checks for
items 2 and 3 (item 1 is already covered by the existing LiveDrawWidget
preflight check; item 4 hard-fails the build by itself). Add an "After
native regeneration" checklist to docs/releasing.md.
## Evidence
`node apps/mobile/scripts/release-preflight.mjs` fails if the tracked
AndroidManifest.xml lacks tools:node="remove" on READ_MEDIA_IMAGES or
READ_MEDIA_VIDEO, or if ios/Sauci/Info.plist contains NSBonjourServices,
NSLocalNetworkUsageDescription, or RCTMetroPort.
`node --test apps/mobile/scripts/release-preflight.test.mjs` covers the new
checks.

scope: apps/mobile local EAS release builds
evidence: v1.0.8 local EAS build session, commit d8bedea
destination: docs/releasing.md
review_after: 2026-11-30
---
## Symptom
Local EAS release builds failed before native compilation for environment
reasons unrelated to the app source, and a successful iOS build left the
tracked source in a state that fails release-preflight afterward.
## Reproduction
Run `eas build --local` from a non-interactive shell without first exporting
ANDROID_HOME/ANDROID_SDK_ROOT/JAVA_HOME: fails with "SDK location not
found" because non-interactive shells do not load the user profile. Run it
with a non-empty EAS_LOCAL_BUILD_WORKINGDIR: fails with "Workingdir is not
empty". Run it outside apps/mobile: eas cannot find the project. Pipe the
build log through `tail`: the full log needed for diagnosis is lost. After a
successful iOS build, EAS auto-increment updates both Info.plists but not
the widget target's CURRENT_PROJECT_VERSION in the pbxproj, so
release-preflight fails until it is synced.
## Cause
`eas` must be installed as a global CLI (scripts call bare `eas`; eas-cli
23.0.0 verified). Non-interactive shells used for automation do not source
the profile that normally exports the Android/Java environment variables.
EAS_LOCAL_BUILD_WORKINGDIR must not exist or be empty. EAS iOS
auto-increment writes plist versions but does not touch the widget target's
pbxproj CURRENT_PROJECT_VERSION, so it drifts from the app's build number by
one increment after every successful build.
## Remediation
Before a local EAS build: verify `eas` is on PATH, explicitly export
ANDROID_HOME, ANDROID_SDK_ROOT, and JAVA_HOME (JDK 17), ensure
EAS_LOCAL_BUILD_WORKINGDIR does not exist or is empty, and run from
apps/mobile. Capture the full build log to a file rather than piping through
`tail`. After a successful build, sync the widget's CURRENT_PROJECT_VERSION
to the new build number (commit d8bedea, sed 46 to 47) and sync
ios/Podfile.lock from the successful build's working directory when
dependencies changed, since the archive's pod install resolution is
authoritative and local CocoaPods here is broken.
## Evidence
docs/releasing.md's local-build section documents the environment
preconditions and the post-build widget CURRENT_PROJECT_VERSION and
Podfile.lock sync steps; `npm run release:preflight` passes after the sync.

## Symptom
CI and the API Docker image (node 20.19.4/npm 10.8.2, per .nvmrc) broke
invisibly while a lockfile regenerated on this dev machine (node 26/npm
11.19) passed local `npm ci`. Pushes to staging bypass required status
checks, so the red CI ran unnoticed for hours.
## Reproduction
Regenerate package-lock.json with npm 11 on a wildcard-range dependency
(react-native-worklets depends on `@react-native/metro-config: "*"`), then
run `npm ci` under node 20.19.4/npm 10.8.2. npm 10 requires 0.85.3 at that
tree position; npm 11 resolves/hoists 0.87.x there. `npm ci` fails with
"Invalid: lock file's ... does not satisfy". The reverse direction also
fails: a lock regenerated by npm 10 fails `npm ci` under npm 11 with missing
platform-optional binaries (@next/swc-linux-x64-gnu breaking `next build`,
@rollup/rollup-linux-x64-gnu breaking the API Docker tsup build, lightningcss
variants breaking local npm ci), matching the npm/cli#4828-style
optional-dependency resolution gap.
## Cause
Two different npm major versions in active use (CI/Docker on npm 10, this
dev machine on npm 11) resolve wildcard/range dependencies to different
versions at the same tree position, and each npm's own platform-optional
binary selection is not portable to the other npm's lockfile.
## Remediation
Pin the wildcard-range dependency via a root package.json override
(`"@react-native/metro-config": "0.85.3"`, alongside the existing
rollup/react-native/expo pins). Pin apps/web `@next/swc` linux/darwin
binaries as direct optionalDependencies (must be bumped together with any
`next` version bump). Regenerate the lock and validate it both ways: local
`npm ci` plus `npm run verify:fast`, and
`docker run --platform linux/amd64 node:20.19.4 ... npm ci` (the
`--platform` flag is mandatory; Apple Silicon Docker otherwise runs arm64
and the platform-binary check is meaningless). After any push that bypassed
required status checks, check `gh run list --branch staging`.
## Evidence
commits 90cde4a and 9609a90 add the override and optionalDependencies pins
and record a lockfile that passes both the amd64-emulated `npm ci` under
node 20.19.4 and local `npm ci` plus `npm run verify:fast`.

# Dependency and lockfile discipline
## Two npm realities
CI runners and the API Docker image use the node version pinned in
`.nvmrc` (node 20.19.4 with npm 10.8.2). A developer machine can run a newer
npm (for example npm 11). npm 10 and npm 11 resolve wildcard or range
dependencies differently at the same place in the dependency tree, and each
npm's platform-optional binary selection is not portable to a lockfile
regenerated by the other npm. A lockfile that passes `npm ci` under one npm
major version can fail it under the other with either an "Invalid: lock
file's ... does not satisfy" error or missing platform-optional binaries
(for example `@next/swc-linux-x64-gnu` breaking `next build`,
`@rollup/rollup-linux-x64-gnu` breaking the API Docker `tsup` build, or a
missing `lightningcss` variant breaking local `npm ci`).
## Pin wildcard-range dependencies with root overrides
When a transitive dependency declares a wildcard or wide range (for example
`react-native-worklets` depending on `@react-native/metro-config: "*"`), pin
the exact version the app needs in the root `package.json` `overrides` block
rather than leaving it to whichever npm resolved the lockfile last:
```json
"overrides": {
"rollup": "4.54.0",
"react-native": "0.85.3",
"expo": "~56.0.0",
"@react-native/metro-config": "0.85.3"
}
```
## Pin platform-optional binaries that must travel with the framework version
`apps/web/package.json` pins the `@next/swc` linux and darwin binaries as
direct `optionalDependencies` so npm does not have to infer them per
platform:
```json
"optionalDependencies": {
"@next/swc-linux-x64-gnu": "15.5.24",
"@next/swc-linux-x64-musl": "15.5.24",
"@next/swc-darwin-arm64": "15.5.24"
}
```
These versions must be bumped together with any `next` version bump, or the
pinned binaries will drift from the framework version and `npm ci` or
`next build` can fail on the platform that needs the stale binary.
## Validate a regenerated lockfile both ways
After changing `overrides` or any dependency version, regenerate
`package-lock.json` and validate it under both npm majors before committing:
```bash
# Local npm (matches this machine's npm major)
npm ci
npm run verify:fast
# The CI/Docker npm major, emulated on Apple Silicon
docker run --rm --platform linux/amd64 -v "$PWD:/repo" -w /repo node:20.19.4 npm ci
```
The `--platform linux/amd64` flag is mandatory on Apple Silicon: without it,
Docker runs the arm64 image and the platform-binary check proves nothing.
## After any bypassed push
Pushes to `staging` bypass required status checks. After any such push, check
`gh run list --branch staging` to confirm CI is actually green rather than
assuming it ran and passed.
Do not pipe `npm` commands through `tail` when diagnosing a lockfile or build
failure; it can swallow the command's exit code and the detail needed to find
the root cause.

**After native regeneration:** `expo prebuild --clean` can silently regress
checked-in native invariants (confirmed during the SDK 54 to 56 upgrade). Before
committing a regenerated project:
- Diff pbxproj signing and identity keys (PRODUCT_BUNDLE_IDENTIFIER,
CODE_SIGN_ENTITLEMENTS) against the last release tag; apple-targets can derive
a widget's bundle identifier from its folder name instead of the pinned config.
- Semantic-diff Info.plist and entitlements files against the last release tag;
prebuild can reintroduce dev-launcher-only keys (NSBonjourServices,
NSLocalNetworkUsageDescription, RCTMetroPort) and drop widget entitlements.
- Check android/gradle.properties for a reset `org.gradle.jvmargs` (prebuild
resets it to the stock -Xmx2048m/512m, which OOMs release Kotlin/CMake tasks).
- Run `npm run release:preflight`; it enforces the Android manifest media
permission removal and rejects the dev-launcher-only Info.plist keys.
- Treat `expo-doctor` unmaintained-package warnings as release blockers on an
SDK upgrade: a package absent from the new SDK's bundledNativeModules can fail
