+- **Android Chat and Voice use tablet space intentionally.** Expanded layouts keep introductions, transcripts, composer controls, and status chrome on readable centered rails, while landscape Voice Focus separates identity controls from conversation activity without changing phone or portrait interaction behavior.

+### Fixed

+- **Windows desktop updates keep the installed CLI and UI on one release.** `hermes-relay update` now detects a colocated management UI, reports both installed versions, and uses the verified bundle installer to replace and restart the affected surfaces together. Explicit CLI-only installations retain the standalone binary updater.

 # Hermes-Relay — Dev Log

+## 2026-09-01 — Exact-tree release artifact promotion
+
+Android Play preflight now packages the signed sideload APK, Play AAB, R8
+mappings, manifest, and public checksums as one immutable tree-keyed artifact.
+Stable approval revalidates and publishes those exact bytes instead of
+recompiling the release after Play accepted the draft. Final DEX and native
+compatibility checks still run against the promoted package.
+
+Required CI records a separate short-lived proof keyed to the complete Git
+tree. Canonical `dev` to `main` promotion reuses that proof only when the
+simulated merge tree is byte-identical; missing evidence or any tree change
+falls back to the full path-aware matrix. Local Android release iteration now
+uses a metadata-and-presentation lane, and a coordinated approval workflow can
+start independent Android, Plugin, and CLI+UI release jobs concurrently.
+The Windows tray lane also carries an exact-source Cargo/target cache from
+trusted branch CI into the tag installer build, with lockfile-scoped incremental
+fallback when tray sources change.
+
+## 2026-09-01 — Unified Windows desktop update contract
+
+The desktop updater now treats a detected Windows management UI as an installed
+bundle rather than updating only the CLI executable. Update checks compare the
+embedded CLI version with the tray executable's product version, expose the
+selected `cli` or `cli_ui` target in JSON, and route drift repair through the
+checksum-verified NSIS installer. Windows installations without the tray keep
+the standalone cooperative CLI swap.
+
+Bundle updates wait for the invoking CLI to exit, stop installer-owned CLI,
+daemon, and tray processes, then restore only the daemon and tray processes that
+were running before the update. Focused tests cover bundle detection, installer
+selection, drift reporting, headless preservation, and stopped-tray behavior.

+## ADR 72 — Plugin and CLI+UI release tags are approval-created
+
+**Status:** Accepted (2026-09-01).
+
+**Context.** Plugin and CLI+UI tag workflows correctly rejected stable tags
+outside `main` and prerelease tags outside `dev`, but that validation occurred
+only after an operator pushed the tag. The CLI+UI release recipe also told
+operators to tag a prerelease from `main`, contradicting the canonical branch
+contract. A rejected tag therefore left a failed check on an otherwise healthy
+release commit and required destructive tag recovery before publication.
+
+**Decision.** The normal Plugin and CLI+UI release path validates first and
+creates the tag second. A single manual approval workflow:
+
+- always runs the trusted workflow definition from `main`, then selects the
+  exact `origin/main` tip for stable versions or `origin/dev` for prereleases;
+- verifies the surface-owned version metadata and matching changelog heading;
+- refuses an existing tag, then creates the exact `server-v*` or `desktop-v*`
+  ref at the validated commit; and
+- dispatches the trusted release workflow from `main`, whose jobs explicitly
+  check out and revalidate that immutable tag.
+
+Direct tag pushes remain a recovery path and retain the same fail-closed
+metadata and branch-containment checks. Approval does not weaken release tests,
+change stable/prerelease source branches, or combine the independently
+versioned Plugin and CLI+UI artifacts.
+
+**Consequences.** Routine releases cannot create a known-invalid tag before
+discovering a branch mismatch. A tag created with `GITHUB_TOKEN` does not
+recursively trigger Actions, so approval explicitly dispatches the release
+workflow and the release workflow supports both tag-push and approved-dispatch
+events. The workflow must exist on `main` before the approval surface is used.
+

+
+## ADR 73 — Release promotion reuses immutable exact-tree evidence
+
+**Status:** Accepted (2026-09-01).
+
+**Context.** A coordinated release previously compiled Android up to four
+times: local release verification, release-prep PR CI, private Play preflight,
+and public tag publication. The canonical `dev` to `main` PR also repeated the
+same path-aware matrix even when its synthetic merge produced the exact Git
+tree already tested before integration. Rebuilding identical source increased
+elapsed time without adding byte-level provenance.
+
+**Decision.** Release evidence is content-addressed by Git tree and promoted
+only through immutable GitHub Actions artifacts.
+
+- Play preflight is the one stable Android signing/build authority. It stores
+  the exact signed sideload APK, Play AAB, both R8 mappings, a manifest with
+  version/commit/tree/size/hash metadata, and checksums for public assets.
+- Stable Android publication downloads that artifact by immutable ID, verifies
+  its successful trusted workflow run and full manifest, reruns package-level
+  DEX/native checks, promotes the existing Play draft, and publishes the same
+  APK/AAB bytes. Prerelease candidates retain their independent build path.
+- Every successful Required-checks run stores a small tree-keyed proof after
+  all selected jobs pass. A canonical `dev` to `main` PR may reuse it only when
+  the simulated merge tree equals the `dev` tree exactly. Missing proof or any
+  content change automatically runs the ordinary matrix.
+- Local Android release iteration runs metadata and release-presentation tests;
+  exact pushed commits still require CI and Play preflight.
+- A coordinated approval workflow dispatches independently validated surface
+  approvals concurrently; it does not combine tags or artifact contracts.
+- Trusted desktop CI and the CLI+UI release workflow share a lockfile- and
+  exact-source-keyed Rust/Tauri target cache. Release tags may restore the
+  default branch's exact build state; cache misses retain the full build path.
+
+**Consequences.** Stable Android bytes are built once, evidence reuse fails
+closed on tree or hash drift, and release PRs avoid duplicate work without
+weakening branch protection. Actions artifact retention becomes part of the
+release window: expired evidence causes a safe rebuild/fallback, never an
+approval bypass.

Client-side capability shipped in alpha.6; server-side prompt-context consumption is on the way (see [ROADMAP.md](https://github.com/Codename-11/hermes-relay/blob/main/ROADMAP.md#desktop-track-parallel-lane-to-android--experimental)).

 4. **POSIX (macOS / Linux):** atomic `fs.rename` over the running binary. The running process keeps the old inode open, so `hermes-relay daemon` (if running) keeps serving until restarted; the next `hermes-relay <verb>` invocation picks up the new binary.
-5. **Windows:** can't replace a running `.exe`, so the updater writes to `<bin>.new.exe` and `finalizePendingUpdate()` runs at the top of `main()` on every subsequent invocation to rename it into place. Result: the swap completes the **next** time you run `hermes-relay`.
