 # Hermes-Relay — Dev Log

+## 2026-08-27 — Fixed issue ownership and bounded PR intake
+
+The automated issue first-response lane now assigns only `Codename-11` when the
+maintainer is absent. The assignee is fixed in the write wrapper rather than
+chosen by webhook or model output, and represents follow-up ownership only—not
+acceptance, priority, implementation, or a release promise.
+
+A separate pull-request route now handles external-contributor, non-bot,
+non-draft `opened`, `reopened`, and `ready_for_review` events. Owner-authored
+`Codename-11` PRs are dropped before model dispatch. Eligible PRs are read from
+live metadata plus trusted `dev` policy/template without executing contributor
+code; the route applies only bounded area/intake labels and posts one
+App-authored intake reply. It cannot approve, request changes, merge, close,
+assign, request reviewers, push, edit PR text, rerun CI, select
+`review-candidate`, or claim correctness. The external-contributor production
+canary retained its exact head/base/open state and proved marker idempotency.
+
+## 2026-08-26 — Canonical pull request intake contract
+
+The repository now supplies one pull request template derived from the structure
+already used by successful Android, plugin, desktop, docs, release, and salvage
+PRs. It asks for a concise summary, focused changes, exact verification, visual
+evidence when applicable, compatibility/risk notes, contributor lineage, and the
+existing cross-surface checklist.
+
+Checkboxes require evidence or an explicit N/A rationale. The template does not
+turn every surface into a mandatory test lane, does not replace CI or maintainer
+review, and keeps normal work targeting `dev` while preserving the documented
+release/hotfix exceptions.
+
+## 2026-08-26 — Bounded public issue triage contract
+
+New GitHub issues may receive one clearly identified Hermes-Relay automated
+triage response grounded in the live report, current code and documentation,
+related open/closed issues, and verified public release state. The lane may add
+existing type/area labels, request focused sanitized diagnostics, and flag a
+thread for maintainer review.
+
+The automated path is intentionally not an issue-lifecycle owner: it cannot
+close, assign, milestone, prioritize, promise a fix/release/timeline, or continue
+replying after the first response. Replies identify themselves as automated and
+explicitly hand the remaining decision to a maintainer. Contributor guidance and
+agent instructions carry the same boundary.
+
+Public labels and comments are attributed to the repository-scoped
+`hermes-relay-triage[bot]` GitHub App rather than a maintainer's personal
+account. The App identity does not expand the bounded action contract.

+#### Generate release copy from the verified changes
+
+When release copy is generated with an agent, this section is the canonical
+authoring contract; do not maintain a separate prompt file.
+
+1. Read the exact Android version/SHA, the Android-only entries selected from
+   `[Unreleased]`, the implemented behavior, and any compatibility or security
+   boundary that users must understand. Do not generate from commit titles or
+   a mixed-surface changelog block alone.
+2. Before editing release files, show a temporary coverage ledger in the task
+   output. Map every selected source change to exactly one placement:
+   `hero`, `secondary`, or `full-only`. Include the change kind (`feature`,
+   `change`, or `fix`) and a short reason. The ledger is review evidence, not a
+   committed public artifact; no selected source item may disappear silently.
+3. Choose exactly one `hero`: the strongest user-facing reason to care about
+   the release. Its summary is one plain-language outcome, and its 1–3 bullets
+   are distinct user benefits rather than implementation steps or filler.
+4. Use `secondary` for other important user-visible features and fixes. The
+   `toastDigest` counts only these items, excluding the hero. Preview the
+   strongest 1–2 secondary items in short phrases. If there are no legitimate
+   secondary items, set both counts to `0` and `preview` to `[]`; the app hides
+   the footer. Never invent an item to satisfy the layout.
+5. Use `full-only` for technically relevant details that belong in
+   `RELEASE_NOTES.md` or `CHANGELOG.md` but would make the collapsed update card
+   noisy. Preserve user-relevant trust and compatibility limits; omit branches,
+   worktrees, CI mechanics, debugging history, and private/operator context.
+6. Write each surface for its audience:
+   - `RELEASE_NOTES.md`: concise Summary plus Added/Changed/Fixed; keep the
+     deterministic Download and Install/Verify scaffolding intact.
+   - `CHANGELOG.md`: complete, crisp public history for the released surface.
+   - `changelog.json`: curated hero, optional improvements, digest, Play copy,
+     and compatibility `sections` for older clients.
+   - `playNotes`: Android-only themes within the rendered 500-character limit.
+7. Before presenting the draft, check that wording begins with user outcomes,
+   avoids unexplained implementation terminology, uses exact public product
+   names, makes no unverified device claim, and passes the public-distribution
+   scrub below.

-/**
- * Clean text-flow chat mode — a full-screen, minimalist third presentation of
- * the agent surface (alongside normal chat and the voice overlay).
- *
- * Centered morphing sphere, a calm themed text flow ([AgentTextFlow]) instead
- * of a persistent transcript, and a thin composer. Mirrors the voice overlay's
- * centered-sphere + bottom-content skeleton (`VoiceModeOverlay.kt:262-280`).
- *
- * Exit is an **explicit control** (top-corner dismiss + system back) — never
- * any-tap, because the in-mode composer needs taps. All mode state lives in
- * the caller as plain UI-local state; this is a presentation over the same
- * conversation, not new ViewModel state.
- *
- * Honors the ambient-visualization preference independently from motion.
- * When visible, [animationEnabled] and OS reduce-motion pause the sphere on a
- * static frame; TalkBack keeps the text readable and announced.
