### Task T001 - Resolve GitHub sync auth assumption

**Started**: 2026-06-02 03:11 **Completed**: 2026-06-02 03:12 **Duration**: 1 minute

**Notes**:

* Resolved that Pantheon sync uses the existing local bridge contract and the local git environment.
* No managed GitHub token flow is added in this session.
* The UI must keep sync behind admin mode, the per-run local token, and an explicit confirmation step.
* Sync errors must be bounded and must not expose raw command output, credentials, repo diffs, or private filesystem paths beyond the typed mirror-root label already returned by the bridge.

**Files Changed**:

* `.spec_system/specs/phase17-session03-pantheon-upgrade-write/implementation-notes.md` - Documented the GitHub sync auth decision.

**BQC Fixes**:

* Trust boundary enforcement: recorded sync confirmation and admin-token gating requirements before enabling the write UI.

***

## Design Decisions

### Decision 1: Pantheon sync uses local git auth

**Context**: The Phase 16 bridge already owns the sync endpoint and executes git via args-array commands in the local environment. **Options Considered**:

1. Add a managed GitHub token flow in the UI - broader threat model and outside this session scope.
2. Reuse the existing bridge contract and local git environment - matches Phase 16 contracts and keeps auth responsibility local.

**Chosen**: Reuse the existing bridge contract and local git environment. **Rationale**: The session is a UI wiring session. Managed token storage would introduce new credential handling, persistence, and audit requirements that are explicitly out of scope.

### Task T002 - Verify Hermes hook and admin contracts

**Started**: 2026-06-02 03:12 **Completed**: 2026-06-02 03:13 **Duration**: 1 minute

**Notes**:

* Confirmed `useHermes` already exposes `pantheon`, `pantheonTemplates`, and `models` as typed `HermesQueryView` contracts.
* Confirmed `useHermesAdmin` already exposes `personas` actions for validate, install defaults, create, update, and delete.
* Confirmed `useHermesAdmin` exposes `pantheonSync.syncMirror(mirrorRoot?)` and sends `{ confirm: "sync" }`.
* Confirmed duplicate-trigger prevention already exists in the hook through scoped in-flight refs.

**Files Changed**:

* `.spec_system/specs/phase17-session03-pantheon-upgrade-write/implementation-notes.md` - Captured contract verification.

**BQC Fixes**:

* Duplicate action prevention: verified hook-level in-flight guards before adding UI actions.
* Contract alignment: verified the UI can consume existing parser-backed types without new endpoint calls.

***

### Task T003 - Map Pantheon state paths and admin gates

**Started**: 2026-06-02 03:13 **Completed**: 2026-06-02 03:14 **Duration**: 1 minute

**Notes**:

* Current `HermesPantheon` accepts only `view` and `demoMode`, renders state blocks for non-data states, and maps persona cards directly from `view.data.personas`.
* `HermesReadOnlyPage` already creates live/demo views and owns the `useHermesAdmin` result, so Pantheon can receive admin, templates, and models from the page without new fetching.
* Admin availability is represented by `admin.status`, `admin.adminEnabled`, `admin.canUseAdmin`, and mutation views that surface offline, token-failure, and disabled states.

**Files Changed**:

* `.spec_system/specs/phase17-session03-pantheon-upgrade-write/implementation-notes.md` - Captured the existing Pantheon state and gate map.

**BQC Fixes**:

* State freshness on re-entry: identified that persona/template state must reset when selection changes or the edit surface closes.

***

### Task T004 - Define Pantheon presentation helpers

**Started**: 2026-06-02 03:14 **Completed**: 2026-06-02 03:16 **Duration**: 2 minutes

**Notes**:

* Added helper coverage for view-state copy, template-state copy, avatar initials, bounded errors, model keys, draft IDs, and YAML model replacement.
* Kept state switches exhaustive for known Hermes query states.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added presentation, state, and formatting helpers.

**BQC Fixes**:

* Failure path completeness: all Pantheon and template query states render explicit copy.
* Error information boundaries: sync/admin errors are redacted and length-bounded before display.

***

### Task T005 - Extend Pantheon props and disabled-state derivation

**Started**: 2026-06-02 03:16 **Completed**: 2026-06-02 03:16 **Duration**: 1 minute

**Notes**:

* Extended Pantheon props to accept templates, models, admin actions, and demo mode.
* Derived write-disabled states from demo mode, `admin.canUseAdmin`, and mutation pending flags.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added template/model/admin props and gate derivation.

**BQC Fixes**:

* Duplicate action prevention: write and sync buttons disable while corresponding mutations are pending.
* Trust boundary enforcement: all writes are disabled unless the admin hook reports usable admin state.

***

### Task T006 - Build YAML draft helpers and re-entry reset

**Started**: 2026-06-02 03:16 **Completed**: 2026-06-02 03:17 **Duration**: 1 minute

**Notes**:

* Added persona, template, and custom draft builders.
* Added state reset on persona/template selection, close, and disappearing selected records.
* Focus moves to the YAML editor when an edit surface opens.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added draft builders, local edit state, reset paths, and editor focus.

**BQC Fixes**:

* State freshness on re-entry: stale selection, validation labels, and draft YAML are reset when context changes.
* Accessibility and platform compliance: the editor receives focus after selection.

***

### Task T007 - Add sync metadata and bounded result formatting

**Started**: 2026-06-02 03:17 **Completed**: 2026-06-02 03:17 **Duration**: 1 minute

**Notes**:

* Added sync step metadata, local-git auth copy, success summary, and redacted error display.
* Sync success reports file count and push status without echoing command output or raw paths.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added sync formatting and step metadata.

**BQC Fixes**:

* Error information boundaries: sync errors are redacted and bounded.
* External dependency resilience: sync has visible pending, success, and failure states.

***

### Task T009 - Wire page data into Pantheon

**Started**: 2026-06-02 03:17 **Completed**: 2026-06-02 03:18 **Duration**: 1 minute

**Notes**:

* Passed live/demo templates, models, and admin contracts into `HermesPantheon`.
* Preserved demo mode by using `HERMES_DEMO_PANTHEON_TEMPLATES`.

**Files Changed**:

* `src/components/hermes/hermes-read-only-page.tsx` - Added Pantheon template demo view and props.

**BQC Fixes**:

* Contract alignment: page wiring passes existing hook contracts directly into the view.

***

### Task T010 - Upgrade persona catalog cards and mode states

**Started**: 2026-06-02 03:18 **Completed**: 2026-06-02 03:18 **Duration**: 1 minute

**Notes**:

* Replaced read-only cards with selectable catalog cards, metadata chips, field fallbacks, and empty/error/offline/token state blocks.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added rich selectable catalog rendering.

**BQC Fixes**:

* Accessibility and platform compliance: persona cards are keyboard-focusable buttons with pressed state and labels.
* Failure path completeness: empty catalog data can still render templates and add-persona actions.

***

### Task T011 - Add persona write controls

**Started**: 2026-06-02 03:18 **Completed**: 2026-06-02 03:18 **Duration**: 1 minute

**Notes**:

* Added validate, create, update, delete, and install-defaults controls using `admin.personas`.
* Added visible action status and sanitized result messages.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added persona write controls and result rendering.

**BQC Fixes**:

* Duplicate action prevention: persona controls disable while `admin.personas.isMutating` is true.
* Trust boundary enforcement: controls are gated by demo/admin/token state.

***

### Task T012 - Add template picker and add-persona tile

**Started**: 2026-06-02 03:18 **Completed**: 2026-06-02 03:18 **Duration**: 1 minute

**Notes**:

* Added template tiles that seed YAML drafts and a custom add-persona tile.
* Template, persona, and custom paths each reset local action state.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added template picker and custom draft tile.

**BQC Fixes**:

* State freshness on re-entry: template and custom draft selection clears stale validation/action state.

***

### Task T013 - Add model dropdown/default-model controls

**Started**: 2026-06-02 03:18 **Completed**: 2026-06-02 03:18 **Duration**: 1 minute

**Notes**:

* Added model options from the declared `HermesModelsBody` catalog and configured default.
* Added an apply-to-draft control and fallback copy for loading/empty model states.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added model option derivation and draft model replacement.

**BQC Fixes**:

* Contract alignment: model choices come from typed hook data instead of ad hoc endpoint calls.

***

### Task T014 - Add GitHub sync panel

**Started**: 2026-06-02 03:18 **Completed**: 2026-06-02 03:19 **Duration**: 1 minute

**Notes**:

* Added confirmation checkbox, optional mirror-root input, step cards, pending state, success state, and bounded error state.
* The sync action calls only `admin.pantheonSync.syncMirror`.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added GitHub mirror sync panel.

**BQC Fixes**:

* Duplicate action prevention: sync button disables while the sync mutation is pending.
* Trust boundary enforcement: confirmation and admin gate are required before sync can run.
* Error information boundaries: sync results do not render raw command output or repo diffs.

***

### Task T015 - Preserve demo-mode templates and admin gating

**Started**: 2026-06-02 03:19 **Completed**: 2026-06-02 03:19 **Duration**: 1 minute

**Notes**:

* Added demo template data to the Pantheon tab and kept admin disabled in demo mode through the existing page-level admin hook options.

**Files Changed**:

* `src/components/hermes/hermes-read-only-page.tsx` - Passed demo/live templates into Pantheon.
* `src/components/hermes/hermes-pantheon.tsx` - Rendered demo write-gate copy.

**BQC Fixes**:

* Trust boundary enforcement: demo mode keeps all write controls disabled.

***

### Task T016 - Add accessible controls

**Started**: 2026-06-02 03:19 **Completed**: 2026-06-02 03:19 **Duration**: 1 minute

**Notes**:

* Added labels for persona cards, templates, draft editor, model select, mirror-root input, sync confirmation, and action buttons.
* Added focus behavior for opened edit contexts.

**Files Changed**:

* `src/components/hermes/hermes-pantheon.tsx` - Added labels, pressed states, and focus handling.

**BQC Fixes**:

* Accessibility and platform compliance: interactive controls expose labels, focus rings, and keyboard-operable button/select/input semantics.

***

### Task T008 - Add Pantheon test fixtures

**Started**: 2026-06-02 03:19 **Completed**: 2026-06-02 03:21 **Duration**: 2 minutes

**Notes**:

* Added Pantheon template fixtures and a reusable Pantheon render props helper.
* Extended admin fixtures through existing persona and sync mutation mocks.

**Files Changed**:

* `src/components/hermes/__tests__/hermes-sections.test.tsx` - Added template data and Pantheon prop helper.

**BQC Fixes**:

* Contract alignment: fixtures use typed `HermesPantheonTemplatesBody`, `HermesModelsBody`, and `UseHermesAdminResult` shapes.

***

### Task T017 - Extend Pantheon component tests

**Started**: 2026-06-02 03:21 **Completed**: 2026-06-02 03:23 **Duration**: 2 minutes

**Notes**:

* Added coverage for rich catalog rendering, template draft seeding, persona write calls, disabled admin hints, sync confirmation, and redacted sync errors.
* Updated existing Pantheon state tests for the expanded prop contract.

**Files Changed**:

* `src/components/hermes/__tests__/hermes-sections.test.tsx` - Added Pantheon workflow assertions.

**BQC Fixes**:

* Duplicate action prevention: component tests assert sync remains disabled until confirmation.
* Trust boundary enforcement: tests assert admin-disabled controls are disabled.
* Error information boundaries: tests assert sync local paths are redacted.

***

### Task T018 - Add admin hook sync duplicate coverage

**Started**: 2026-06-02 03:23 **Completed**: 2026-06-02 03:24 **Duration**: 1 minute

**Notes**:

* Confirmed existing hook coverage sends `{ confirm: "sync" }`.
* Added duplicate-trigger coverage for `pantheonSync.syncMirror` while a request is in flight.

**Files Changed**:

* `src/hooks/__tests__/use-hermes-admin.test.tsx` - Added Pantheon sync in-flight guard test.

**BQC Fixes**:

* Duplicate action prevention: hook test verifies only one sync request can run at a time.
* Contract alignment: hook test verifies sync request body includes the confirmation payload and mirror root.

***

### Task T019 - Run focused Hermes tests, typecheck, and lint

**Started**: 2026-06-02 03:24 **Completed**: 2026-06-02 03:26 **Duration**: 2 minutes

**Notes**:

* Focused Hermes component/admin-hook tests passed.
* Scripted typecheck passed.
* Full lint initially found two mechanical `no-unused-expressions` errors in `src/components/hermes/chat/chat-composer.tsx`; replaced short-circuit assignments with `if` statements and reran lint successfully.
* Full lint still reports pre-existing fast-refresh warnings in Hermes primitive/status files, but exits successfully with no errors.

**Files Changed**:

* `src/components/hermes/chat/chat-composer.tsx` - Replaced two short-circuit input resets with explicit `if` statements.
* `.spec_system/specs/phase17-session03-pantheon-upgrade-write/implementation-notes.md` - Recorded verification results.

**BQC Fixes**:

* Failure path completeness: upload input cleanup remains explicit in unsupported-file and finally paths.

***

### Task T020 - Record mode matrix and ASCII validation

**Started**: 2026-06-02 03:26 **Completed**: 2026-06-02 03:27 **Duration**: 1 minute

**Notes**:

* Mode coverage recorded from component tests and code review:
  * Demo mode: demo fixtures flow through Pantheon templates and writes remain disabled.
  * Live/read-ready: catalog, templates, model controls, persona writes, and sync render from typed hook/admin contracts.
  * Setup/admin-disabled: admin-disabled banner and disabled persona/sync actions render.
  * Offline/token/error/empty/loading: Pantheon and template state-copy switches render explicit state blocks.
  * Pending/success/error mutation states: persona and sync action status render visible feedback without raw command output.
* ASCII validation passed for touched source, test, and session files.
* LF validation passed for touched source, test, and session files.

**Files Changed**:

* `.spec_system/specs/phase17-session03-pantheon-upgrade-write/implementation-notes.md` - Recorded mode matrix and encoding validation.

**BQC Fixes**:

* Failure path completeness: documented coverage for offline, token, endpoint-error, empty, loading, pending, success, and error states.
* Error information boundaries: documented sync output redaction and no raw command output exposure.
