Final line counts: Memory card 503, Obsidian bridge 296, formatting helper 36. * No unrelated validation failures were observed. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Refactored to keep the Memory read surface cohesive. * `src/components/hermes/hermes-obsidian-bridge.tsx` - Added focused Obsidian bridge component. * `src/components/hermes/hermes-memory-format.ts` - Added shared bounded text/path/error helpers. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T021 complete and completed the checklist. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded final validation results. **Validation Results**: * `bunx vitest run src/components/hermes/__tests__/hermes-sections.test.tsx src/hooks/__tests__/use-hermes-admin.test.tsx src/lib/__tests__/hermes-admin-types.test.ts scripts/lib/__tests__/hermes-admin-bridge.test.ts` - passed, 4 files, 106 tests. * `bun run typecheck` - passed. * `bun run lint` - passed. * ASCII validation over touched files - passed. **BQC Fixes**: * Failure path completeness: Focused tests cover memory, sessions, profiles, and Obsidian non-success states. * Error information boundaries: ASCII and focused tests verify bounded/redacted Obsidian error display paths. * Contract alignment: Typecheck and parser/hook/bridge tests verify UI contracts remain aligned with existing Hermes bridge shapes. *** ## Design Decisions ### Decision 1: Split Obsidian bridge into a focused module **Context**: The initial Memory card implementation grew beyond the project guideline for moderately sized modules. **Options Considered**: 1. Keep all Memory and Obsidian logic in `hermes-memory-card.tsx` - simpler import graph, but the file reached 817 lines and mixed read rendering with write controls. 2. Split Obsidian bridge and shared formatting helpers into local Hermes modules - keeps the Memory card centered on read composition while preserving the same public component API. **Chosen**: Option 2. **Rationale**: The Obsidian bridge is a separate admin write surface with persistence, confirmation, and mutation feedback. Moving it into `hermes-obsidian-bridge.tsx` keeps responsibilities cohesive without widening bridge behavior. *** ### Task T020 - Add Obsidian admin hook coverage **Started**: 2026-06-02 04:23 **Completed**: 2026-06-02 04:24 **Duration**: 1 minutes **Notes**: * Existing hook tests already confirmed Obsidian payload shape includes `confirm: "obsidian"`. * Added a dedicated duplicate-write test for `obsidian.connectVault()` while the first Obsidian request is in flight. * Focused hook test command passed: `bunx vitest run src/hooks/__tests__/use-hermes-admin.test.tsx`. **Files Changed**: * `src/hooks/__tests__/use-hermes-admin.test.tsx` - Added Obsidian duplicate-write coverage. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T020 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded hook test notes. **BQC Fixes**: * Duplicate action prevention: Hook tests now assert only one `/__hermes_obsidian` request is sent during concurrent connect attempts. *** ### Task T019 - Extend Memory component tests **Started**: 2026-06-02 04:22 **Completed**: 2026-06-02 04:23 **Duration**: 1 minutes **Notes**: * Updated Memory component tests for expanded props. * Added coverage for memory layers, SOUL cleanup, conversation states, profile fallbacks, Obsidian disabled/confirm/pending/success/error states, sanitized error output, and disconnect reset. * Focused component test command passed: `bunx vitest run src/components/hermes/__tests__/hermes-sections.test.tsx`. **Files Changed**: * `src/components/hermes/__tests__/hermes-sections.test.tsx` - Added expanded Memory component coverage. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T019 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded component test notes. **BQC Fixes**: * Failure path completeness: Component tests now assert Memory, sessions, profiles, and Obsidian failure states. * Duplicate action prevention: Component tests assert confirmation and disabled controls before write calls. *** ### Task T018 - Add accessibility labels and keyboard support **Started**: 2026-06-02 04:21 **Completed**: 2026-06-02 04:22 **Duration**: 1 minutes **Notes**: * Added accessible labels for memory layers, profile summary cards, budget rings, vault input helper copy, and confirmation checkbox. * Used native form, input, checkbox, and button semantics for keyboard support. * Preserved focus-visible ring styling on actionable controls. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added labels and keyboard-friendly controls. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T018 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded accessibility notes. **BQC Fixes**: * Accessibility and platform compliance: Interactive controls use native elements, labels, focus states, and descriptive ARIA where visual-only elements exist. *** ### Task T017 - Preserve read and write gating **Started**: 2026-06-02 04:20 **Completed**: 2026-06-02 04:21 **Duration**: 1 minutes **Notes**: * Demo mode continues to pass fixture views and disables admin through `useHermesAdmin({ enabled: !demoMode })`. * Live mode continues to use token-gated `memory`, `sessions`, and `profiles` hook views. * Updated the footer copy to include Obsidian writes in the admin-gated write surface list. **Files Changed**: * `src/components/hermes/hermes-read-only-page.tsx` - Preserved live/demo gating and updated write-surface copy. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T017 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded gating notes. **BQC Fixes**: * Trust boundary enforcement: Demo mode does not enable Obsidian writes and live sensitive reads remain token-gated by `useHermes`. *** ### Task T016 - Render Obsidian mutation and reset states **Started**: 2026-06-02 04:19 **Completed**: 2026-06-02 04:20 **Duration**: 1 minutes **Notes**: * Added pending status through the bridge status chip and connect-button spinner. * Added sanitized success and error feedback, persisted connected state, and explicit disconnect control. * Reset confirmation and old mutation feedback on vault path changes, demo/live changes, and disconnect. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added Obsidian mutation feedback and state reset behavior. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T016 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded mutation state notes. **BQC Fixes**: * State freshness on re-entry: Confirmation and result visibility reset when the path or mode changes and when disconnecting. * Error information boundaries: Success and error states display `[local path]/name` style labels or redacted errors only. *** ### Task T015 - Add Obsidian bridge controls **Started**: 2026-06-02 04:18 **Completed**: 2026-06-02 04:19 **Duration**: 1 minutes **Notes**: * Added vault-path input, explicit confirmation checkbox, admin-disabled hint copy, and connect button. * Derived connect availability from demo mode, offline state, token failure, admin state, path presence, confirmation, and in-flight mutation state. * Disabled path edits and submissions during pending Obsidian mutation state. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added guarded Obsidian controls. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T015 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded Obsidian control notes. **BQC Fixes**: * Duplicate action prevention: The connect button is disabled during pending writes and the hook still rejects concurrent writes. * Trust boundary enforcement: The UI cannot call `connectVault` without admin readiness, token readiness, path input, and confirmation. *** ### Task T014 - Add profile memory grid **Started**: 2026-06-02 04:17 **Completed**: 2026-06-02 04:18 **Duration**: 1 minutes **Notes**: * Added `ProfileMemoryGrid` using the existing token-gated profiles view. * Rendered active/standby status, model, gateway, alias, and distribution with bounded null fallbacks. * Avoided rendering raw profile memory bodies or any fields outside the exposed summary contract. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added profile memory grid. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T014 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded profile grid notes. **BQC Fixes**: * Trust boundary enforcement: The grid renders only the parser-backed `HermesProfileSummary` fields. * Contract alignment: Empty, error, offline, and token-failure profile states use the shared query view contract. *** ### Task T013 - Add conversation-history callout **Started**: 2026-06-02 04:16 **Completed**: 2026-06-02 04:17 **Duration**: 1 minutes **Notes**: * Added `ConversationHistoryCallout` using the existing token-gated sessions view. * Rendered session count, loaded count, latest update label, and a bounded latest-session preview. * Added explicit idle, loading, empty, error, offline, and token-failure state blocks independent from curated memory. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added conversation-history callout. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T013 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded conversation callout notes. **BQC Fixes**: * Failure path completeness: Sessions errors and token failures now have their own visible failure path inside Memory. *** ### Task T012 - Add SOUL prose rendering **Started**: 2026-06-02 04:15 **Completed**: 2026-06-02 04:16 **Duration**: 1 minutes **Notes**: * Added SOUL-specific cleanup for template-only files, frontmatter, HTML comments, and placeholder lines. * Rendered SOUL as bounded prose with a separate empty fallback and no character-budget ring. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Implemented SOUL cleanup and prose rendering. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T012 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded SOUL rendering notes. **BQC Fixes**: * Error information boundaries: SOUL rendering strips template and comment noise before display. *** ### Task T011 - Add USER and MEMORY budgeted sections **Started**: 2026-06-02 04:14 **Completed**: 2026-06-02 04:15 **Duration**: 1 minutes **Notes**: * Added USER and MEMORY section splitting with a maximum section count and per-section character bound. * Added accessible character-budget rings with percent, count, and limit labels. * Added explicit empty cards when a memory file is missing or has no renderable sections. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Implemented bounded USER/MEMORY rendering and budget indicators. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T011 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded budgeted section notes. **BQC Fixes**: * Accessibility and platform compliance: Budget rings expose descriptive `aria-label` text instead of relying on visual rings only. *** ### Task T010 - Upgrade Memory tab layout and states **Started**: 2026-06-02 04:11 **Completed**: 2026-06-02 04:14 **Duration**: 3 minutes **Notes**: * Replaced the single excerpt grid with a Memory manuscript panel containing memory layers, conversation history, profile memory, and Obsidian bridge blocks. * Added shared state-copy handling for idle, loading, empty, error, offline, token-failure, success, and demo paths. * Ran focused ESLint on the edited component files after formatting; no lint errors remained. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Implemented the expanded Memory layout and state blocks. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T010 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded layout notes. **BQC Fixes**: * Failure path completeness: Non-success Memory states now render caller-visible state blocks instead of blank or partial panels. *** ### Task T009 - Wire read-only page Memory props **Started**: 2026-06-02 04:10 **Completed**: 2026-06-02 04:11 **Duration**: 1 minutes **Notes**: * Added live/demo `profiles` view derivation beside the existing `memory` and `sessions` views. * Passed `sessions`, `profiles`, and `admin` into `HermesMemoryCard` while preserving existing demo/live reset behavior. **Files Changed**: * `src/components/hermes/hermes-read-only-page.tsx` - Wired expanded Memory props. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T009 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded wiring notes. **BQC Fixes**: * Contract alignment: Demo and live Memory props are now derived from the same hook-shaped `HermesQueryView` contracts. *** ### Task T008 - Add Memory test fixtures **Started**: 2026-06-02 04:09 **Completed**: 2026-06-02 04:10 **Duration**: 1 minutes **Notes**: * Added `HermesProfilesBody` fixture data with active, standby, and missing-field profile summaries. * Added reusable `memoryProps()` and `obsidianAdminFixture()` helpers for focused Memory component tests. **Files Changed**: * `src/components/hermes/__tests__/hermes-sections.test.tsx` - Added Memory/profile/admin fixtures for expanded Memory card tests. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T008 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded fixture notes. **BQC Fixes**: * Contract alignment: Test fixtures model the exact `HermesProfilesBody` and `UseHermesAdminResult` contracts consumed by the component. *** ### Task T007 - Extend Hermes demo profile fixtures **Started**: 2026-06-02 04:08 **Completed**: 2026-06-02 04:09 **Duration**: 1 minutes **Notes**: * Added a demo profile with null model, gateway, alias, and distribution fields so the Memory profile grid exercises fallback rendering in demo mode. **Files Changed**: * `src/lib/hermes-demo-data.ts` - Added a fallback-oriented demo profile. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T007 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded fixture update notes. **BQC Fixes**: * Contract alignment: Demo data still matches `HermesProfilesBody` and uses only safe summary fields. *** ### Task T006 - Define Obsidian bridge helpers **Started**: 2026-06-02 04:07 **Completed**: 2026-06-02 04:08 **Duration**: 1 minutes **Notes**: * Added local vault-path persistence with guarded `localStorage` access and an AI OS namespaced key. * Added persisted connected state, disconnect handling, and confirmation reset on vault path or demo/live changes. * Added sanitized success and error display helpers so the UI shows bounded local-path labels instead of raw private paths or command output. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added Obsidian persistence, confirmation, sanitization, and reset helpers. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T006 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded Obsidian helper notes. **BQC Fixes**: * State freshness on re-entry: Confirmation and old mutation feedback reset on vault-path and mode changes, and disconnect clears connected state. * Error information boundaries: Success and error feedback use sanitized local path labels. *** ### Task T005 - Define memory layer helpers **Started**: 2026-06-02 04:06 **Completed**: 2026-06-02 04:07 **Duration**: 1 minutes **Notes**: * Added layer metadata for USER, MEMORY, and SOUL. * Added bounded section splitting for USER and MEMORY, including support for the upstream section separator through an ASCII escape. * Added SOUL cleanup for frontmatter, HTML comments, template placeholders, template-only state, and bounded prose rendering. * Added character-budget percentage and path/error/status formatting helpers. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added memory layer helper functions and bounded display helpers. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T005 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded helper implementation notes. **BQC Fixes**: * Error information boundaries: Local filesystem paths and long token-like strings are redacted in error output. * Contract alignment: Layer helpers consume only the parser-backed `HermesMemoryBody` fields already exposed by the bridge. *** ### Task T004 - Extend Memory card props and disabled-state derivation **Started**: 2026-06-02 04:02 **Completed**: 2026-06-02 04:06 **Duration**: 4 minutes **Notes**: * Expanded `HermesMemoryCard` props to accept `memory`, `sessions`, `profiles`, `admin`, and `demoMode` contracts. * Added exhaustive Obsidian disabled-state derivation for demo mode, offline state, token failure, admin-disabled state, admin-not-ready state, empty path, missing confirmation, and in-flight mutation. * Kept the Memory card controlled by existing hook contracts with no ad hoc endpoint calls. **Files Changed**: * `src/components/hermes/hermes-memory-card.tsx` - Added expanded props and guarded Obsidian disabled-state derivation. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T004 complete and updated progress. * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded implementation notes. **BQC Fixes**: * Duplicate action prevention: Connect submission is disabled while the Obsidian mutation is in flight, and the existing hook rejects concurrent writes. * Trust boundary enforcement: UI write capability is derived from admin status, token state, browser online state, explicit confirmation, and hook mutation state. *** ### Task T003 - Map current Memory card gaps **Started**: 2026-06-02 04:01 **Completed**: 2026-06-02 04:02 **Duration**: 1 minutes **Notes**: * Current `HermesMemoryCard` accepts only `view` and `demoMode`, so it cannot render sessions, profiles, or Obsidian admin state. * Current layer UI renders simple excerpt cards and does not split USER/MEMORY sections, clean SOUL frontmatter/template/comment noise, or show bounded budget feedback beyond raw counts. * Current state handling covers only the memory view and does not include separate conversation-history or profile-grid states. * Current card has no vault path persistence, confirmation checkbox, disconnect state, pending/success/error feedback, or duplicate-trigger UI prevention for Obsidian. **Files Changed**: * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded the gap map before code edits. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T003 complete and updated progress. **BQC Fixes**: * Contract alignment: Identified required prop expansion before editing so new UI remains tied to existing hook contracts. * State freshness on re-entry: Flagged vault confirmation/result reset as required implementation work. *** ### Task T002 - Verify existing hook contracts for reuse **Started**: 2026-06-02 04:00 **Completed**: 2026-06-02 04:01 **Duration**: 1 minutes **Notes**: * Verified `useHermes()` already exposes `memory`, `sessions`, and `profiles` as `HermesQueryView` values with idle, loading, empty, error, offline, token-failure, success, and demo state semantics. * Verified sensitive reads are gated by `sensitiveReadsEnabled`, which requires browser mode, online state, Hermes ready state, a local token, and no token query failure. * Verified `useHermesAdmin()` already exposes `obsidian.connectVault(vaultPath)` and sends `{ vaultPath, confirm: "obsidian" }` through `/__hermes_obsidian`. * Verified the admin hook prevents duplicate Obsidian writes with `obsidianInFlightRef`, mutation pending state, and `canUseAdmin`. **Files Changed**: * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Recorded hook contract findings. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T002 complete and updated progress. **BQC Fixes**: * Duplicate action prevention: Confirmed the hook-level Obsidian mutation path already rejects concurrent writes. * Contract alignment: Confirmed the UI can consume existing `HermesQueryView`, `HermesProfilesBody`, `HermesSessionsBody`, and `UseHermesAdminResult` contracts without endpoint drift. *** ### Task T001 - Resolve upstream Memory anchors and write-safety assumptions **Started**: 2026-06-02 03:59 **Completed**: 2026-06-02 04:00 **Duration**: 1 minutes **Notes**: * Reviewed the v2.3 `HermesMemorySection` anchor in `/home/aiwithapex/projects/claudeos/claude-os-v2.3/src/routes/agents.hermes.tsx`. * Confirmed the target composition: USER, MEMORY, and SOUL manuscript layers, a separate conversation-history strip, profile memory grid, and Obsidian bridge. * Confirmed this session must not widen bridge behavior. The existing `useHermesAdmin().obsidian.connectVault()` path owns the write and sends the required confirmation payload. * Obsidian safety assumptions remain: local dev bridge, loopback enforcement, token requirement, admin gate, allow-listed write behavior, path confinement, explicit confirmation, and no raw command output in UI. **Files Changed**: * `.spec_system/specs/phase18-session01-memory-upgrade-write/implementation-notes.md` - Created the session implementation log and recorded upstream anchor findings. * `.spec_system/specs/phase18-session01-memory-upgrade-write/tasks.md` - Marked T001 complete and updated progress. **BQC Fixes**: * Trust boundary enforcement: Kept the implementation plan bound to existing parser-backed read views and the existing admin mutation instead of adding ad hoc fetches. *** ## Task Log ### 2026-06-02 - Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready *** --- # Agent Instructions This documentation is published with GitBook.
