dtourolleandClaude Opus 5 eaafacc3fb Give the phone the model it had no way to obtain
Face indexing was compiled into the APK all along — dr-ui takes dr-face with
`inference` on every target, so SCRFD, alignment, MBF, calibration and
clustering were all in there. What was missing was the weights, and on Android
there was no way to supply them.

Route C (docs/faces.md §2.2) says the user obtains the model and the app loads
it. On a desktop that is a real gesture: drop two files in
~/.local/share/darkroom/models/ and indexing starts working. On Android it is
not a gesture at all. `internal_data_path` is app-private, `run-as` needs a
debuggable build, and the in-app fetch route C specifies was never built — so
the settings page reported "no face model is installed" on every launch with
nothing behind the message. Not "off until you supply weights"; off.

So the shape-fixed pair goes into LFS under the APK's assets, assemble-apk.sh
copies it into the package, and `android_main` unpacks it to the shared models
directory before anything asks whether a model is present.

Three things that are not incidental:

The models directory is now shared across accounts rather than per-account.
Weights are identified by `faces.model_id`, not by who is signed in, so two
accounts had no reason to hold two copies — and the unpack runs before any
session exists to key a per-account path off. `face_models` still prefers a
per-account directory when one is populated, so anyone mid-migration keeps the
ability to pin one library to its own pair.

The unpack writes under a temporary name and renames. `face_models` decides
availability on `is_file()` alone, so a copy truncated by the process being
killed would leave a file that passes that test and fails inside tract —
reported to the user as a broken model rather than a missing one.

assemble-apk.sh refuses an LFS pointer. At ~130 bytes it looks exactly like a
model to `cp`, and unchecked it reaches the device and fails in the graph
loader instead of telling someone to run `git lfs pull` — the same guard
dr-segment's build script applies to yolo26n-seg.onnx.

The licensing half is unchanged and recorded in §2.2a: the InsightFace grant is
research-only, this is a private repository and a self-installed build, and
these files come back out before anything is published. The weights are still
not a cargo build input — dr-face has no `models/` directory and no
`embedded-model` feature, and nothing in the build reads them. The APK assembly
step copies two files and is the only thing in the tree that knows they exist.

Verified on device: both models unpack on first launch (2524817 and 13616095
bytes) and the APK carries them at assets/models/.

The APK has been debug-signed with a key generated on the spot, which is
right for putting a build on a test device and useless for anything else:
a different signature every run, so nothing can ever update in place.

Four secrets now select a real signature -- ANDROID_KEYSTORE_BASE64 and
its password, alias and key password. The names are JellyTau's, because
that repo already signs its Android build this way against this same
runner and one convention across both is one thing to remember.

Absence of the secrets is not an error. A fork or a branch build has no
access to them and should still produce an installable APK, so the debug
path stays exactly as it was. The reverse is an error: if a keystore is
supplied and cannot be read, the build fails rather than quietly falling
back to a debug key, because a release that is silently debug-signed is
worse than no release.

Passwords reach apksigner and keytool as `env:`, never `pass:`. `pass:`
puts the password in the process table for anything on the box to read.
The keystore is written to a 0700 mktemp directory and never into the
workspace, which is both what actions/cache saves and what the upload
step globs.

Also: upload-artifact drops from v4 to v3. v4 was a guess about what this
Gitea supports. v3 is what JellyTau uploads its APK with on this runner
today, which makes it the version known to work rather than the one that
ought to.

dtourolleandClaude Opus 5 5741ec5e00 Lift the APK assembly out of package.sh so CI can run it too
package.sh does two things: it decides how the host reaches the image, and
it assembles an APK once inside it. Only the first half is host-specific.
CI already runs in that image, so the second half was about to be copied
into a workflow step -- two copies of aapt2/zipalign/apksigner ordering,
drifting apart at whatever rate the toolchain moves.

So it moves to docker/android/assemble-apk.sh, which assumes it is inside
the image and takes its paths from the environment, because the callers
disagree about them: the container mounts the repo at /work, the runner
checks it out wherever it likes. Every default reproduces what package.sh
did, so the host path is unchanged.

Two things stop being hard-coded on the way. The build-tools version and
the compile SDK are resolved from what is installed rather than written
out as 36.0.0 and android-36 -- the versions are Dockerfile ARGs, and a
second copy is a second thing to miss when they move. --min-sdk-version
now comes from that same ARG instead of a literal 28, which is the number
the API-level check in CI already reads.

The intermediates are removed at the end. They were harmless in a cache
directory nobody looks at; beside a published artefact they are four more
files for a glob to pick up by mistake.
