Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Directory structure ready * [x] Bun available * [x] Project-local React, TypeScript, and Vitest dependencies present *** ### Task T001 - Verify prerequisites and admin bridge scope **Started**: 2026-06-09 16:08 **Completed**: 2026-06-09 16:09 **Duration**: 1 minute **Notes**: * Verified Sessions 03 and 05 are completed in `.spec_system/state.json`. * Verified `/__token` is a loopback-only GET endpoint returning `{ token }` without logging token values. * Verified `useKnowledgeGraphAdmin` exports status, ingest, and remove views with tokenized writes and duplicate write prevention. * Confirmed the Session 06 PRD stub scope matches ingest UI, connect prompt, starter chips, mini stats, and tests. **Files Changed**: * `.spec_system/specs/phase26-session06-ingest-ui-connect-prompt-starter-chips/implementation-notes.md` - Created implementation log. **BQC Fixes**: * None; inspection task only. ### Task T004 - Create Knowledge Graph token query hook **Started**: 2026-06-09 16:11 **Completed**: 2026-06-09 16:15 **Duration**: 4 minutes **Notes**: * Added a narrow `/__token` hook with typed idle, loading, success, offline, demo, and error states. * Added a parser guard for non-object, missing, empty, or non-string token responses. * Kept token values out of status/error text and relied on React Query's abort signal for cleanup. **Files Changed**: * `src/hooks/use-knowledge-graph-token.ts` - Added token query hook and response parser. **BQC Fixes**: * Trust boundary: malformed token responses fail closed before reaching the admin hook. * Failure path completeness: token fetch and parser failures surface explicit UI-consumable error text. ### Task T005 - Create safe connect prompt builder and starter definitions **Started**: 2026-06-09 16:15 **Completed**: 2026-06-09 16:18 **Duration**: 3 minutes **Notes**: * Added a pure prompt builder with registry path and active project insertion. * Added deterministic starter-question definitions for overview, load-bearing files, change impact, and risk scan. * Replaced upstream shell/script registration guidance with AI OS UI-mediated registration instructions. **Files Changed**: * `src/lib/knowledge-graph-connect-prompt.ts` - Added prompt builder, registry-path helper, and starter question constants. **BQC Fixes**: * Error information boundaries: copied prompt avoids auth headers, bridge route names, and raw command instructions. * Trust boundary: new project registration guidance stays on the AI OS UI/admin path. ### Task T006 - Create Knowledge Graph mini stat tile **Started**: 2026-06-09 16:18 **Completed**: 2026-06-09 16:20 **Duration**: 2 minutes **Notes**: * Added a reusable compact stat tile with stable minimum height, tabular value text, and truncation. * Kept the component presentational and dependency-free beyond existing utilities. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-mini-stat.tsx` - Added reusable mini stat component. **BQC Fixes**: * Accessibility and platform compliance: stat text stays readable without interactive semantics. * Contract alignment: component accepts plain React values and optional accent/class props for existing gallery and rail contexts. ### Task T007 - Define ingest card props and state model **Started**: 2026-06-09 16:20 **Completed**: 2026-06-09 16:28 **Duration**: 8 minutes **Notes**: * Added `KnowledgeGraphIngestCard` props around the read view, token view, admin view, and post-write refresh callback. * Added a derived gate model for ready, loading, demo, offline, admin-disabled, token-failure, graphify-missing, and error states. * Added local form, confirmation, and in-flight refs to support reset on close/re-entry and duplicate-trigger prevention. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-ingest-card.tsx` - Added ingest card contract, gate model, and local state skeleton with behavior. **BQC Fixes**: * State freshness on re-entry: local input, confirmation, and form errors reset on close/re-entry. * Duplicate action prevention: local in-flight refs complement the admin hook's write guard. ### Task T008 - Define connect prompt card props and clipboard state **Started**: 2026-06-09 16:28 **Completed**: 2026-06-09 16:33 **Duration**: 5 minutes **Notes**: * Added a collapsible `KnowledgeGraphConnectPrompt` component with registry, project, graph, accent, and class props. * Added clipboard success, textarea fallback, and redacted error states. * Reset copy state on collapse and prompt input changes. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-connect-prompt.tsx` - Added connect prompt component. **BQC Fixes**: * Failure path completeness: clipboard API and fallback failures surface visible redacted copy guidance. * Error information boundaries: clipboard errors do not expose raw exception details. ### Task T009 - Define starter chip event dispatch helpers **Started**: 2026-06-09 16:33 **Completed**: 2026-06-09 16:36 **Duration**: 3 minutes **Notes**: * Added `KnowledgeGraphStarterChips` with deterministic question rendering and accessible buttons. * Added `dispatchKnowledgeGraphStarterQuestion` to emit `hermes-chat-prefill` with prompt text as event detail. * Kept the future chat anchor optional; missing anchor is a clean no-op after event dispatch. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-starter-chips.tsx` - Added starter chip component and dispatch helper. **BQC Fixes**: * Accessibility and platform compliance: starter actions are native focusable buttons with explicit labels. * State freshness on re-entry: repeated clicks dispatch fresh events without storing component state. ### Task T010 - Implement ingest card gate states and UI **Started**: 2026-06-09 16:36 **Completed**: 2026-06-09 16:40 **Duration**: 4 minutes **Notes**: * Implemented collapsed and expanded ingest UI with path/URL input, optional display name, status details, and active graph context. * Surfaced loading, empty registry, error, offline, demo, admin-disabled, token-failure, and graphify-missing states from typed view data. * Kept unavailable states visible and non-mutating rather than silently hiding controls. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-ingest-card.tsx` - Added ingest UI and explicit state copy. **BQC Fixes**: * Failure path completeness: every disabled or failed gate has visible operator-facing detail. * Accessibility and platform compliance: controls use labels, status text, and focus-visible styles. ### Task T011 - Implement hook-mediated ingest submit **Started**: 2026-06-09 16:40 **Completed**: 2026-06-09 16:41 **Duration**: 1 minute **Notes**: * Implemented submit through `admin.ingest.run` only; no component-owned bridge fetches were added. * Trimmed path input, omitted empty optional display names, cleared successful input, and left failed input available for correction. * Added local in-flight guard and disabled controls while admin mutations are pending. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-ingest-card.tsx` - Added ingest submit behavior. **BQC Fixes**: * Duplicate action prevention: ref guard and disabled controls block double-submit races. * Trust boundary: all mutation transport remains inside `useKnowledgeGraphAdmin`. ### Task T012 - Implement active graph remove action **Started**: 2026-06-09 16:41 **Completed**: 2026-06-09 16:42 **Duration**: 1 minute **Notes**: * Added confirm-before-remove behavior for the active graph. * Revalidates `activeProject.id` against `activeProjectId` before calling `admin.remove.run`. * Disables remove while writes are pending and calls the page refresh callback after successful removal. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-ingest-card.tsx` - Added remove confirmation and hook-mediated remove action. **BQC Fixes**: * State freshness on re-entry: remove confirmation resets when state changes, closes, or succeeds. * Contract alignment: remove sends only the active id through the existing admin mutation view. ### Task T013 - Implement copyable connect-with-Hermes prompt card **Started**: 2026-06-09 16:42 **Completed**: 2026-06-09 16:43 **Duration**: 1 minute **Notes**: * Implemented safe prompt preview and copy behavior through the pure prompt builder. * Added clipboard API success, textarea fallback, copied state timeout, and redacted failure text. * Copied output avoids auth values, auth header names, curl, and private bridge mutation paths. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-connect-prompt.tsx` - Added prompt preview and copy behavior. * `src/lib/knowledge-graph-connect-prompt.ts` - Supplies safe copied prompt text. **BQC Fixes**: * Error information boundaries: copy failures never expose browser exception detail. * Trust boundary: prompt guides new project registration through the AI OS UI. ### Task T014 - Implement starter-question chips **Started**: 2026-06-09 16:43 **Completed**: 2026-06-09 16:44 **Duration**: 1 minute **Notes**: * Implemented starter chips from deterministic prompt definitions. * Dispatches `hermes-chat-prefill` with prompt text and preserves page state. * Optional scroll target is checked at click time and missing anchors are ignored. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-starter-chips.tsx` - Added starter chip rendering and dispatch behavior. **BQC Fixes**: * Accessibility and platform compliance: chips are keyboard-focusable native buttons with clear labels. * Failure path completeness: absent chat anchor is a no-op rather than an exception. ### Task T015 - Wire token/admin hooks and new cards into page **Started**: 2026-06-09 16:44 **Completed**: 2026-06-09 16:50 **Duration**: 6 minutes **Notes**: * `KnowledgeGraphPage` now composes `useKnowledgeGraphToken` and `useKnowledgeGraphAdmin`. * Passed read, token, admin, and refetch views into the gallery-hosted ingest card. * Added starter chips and connect prompt composition without changing the route file. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-page.tsx` - Wired token/admin hooks, starter chips, connect prompt, and refetch handoff. * `src/components/knowledge-graph/knowledge-graph-project-gallery.tsx` - Accepts token/admin/refresh props and renders the ingest card. **BQC Fixes**: * Contract alignment: write UI consumes the established admin hook contract instead of direct endpoint fetches. * State freshness on re-entry: post-write refresh callback lets the read hook reconcile registry and active selection. ### Task T016 - Reuse mini stat tile in gallery and side rail **Started**: 2026-06-09 16:50 **Completed**: 2026-06-09 16:51 **Duration**: 1 minute **Notes**: * Replaced gallery metric markup with `KnowledgeGraphMiniStat`. * Replaced side rail graph and savings metrics with the same stat tile. * Preserved existing read fallback, selection, and rail behavior. **Files Changed**: * `src/components/knowledge-graph/knowledge-graph-project-gallery.tsx` - Uses mini stat tiles in project cards and hosts ingest card. * `src/components/knowledge-graph/knowledge-graph-side-rail.tsx` - Uses mini stat tiles for graph and savings metrics. **BQC Fixes**: * Contract alignment: shared visual component only changes presentation, not read-state behavior. * Accessibility and platform compliance: metric tiles remain non-interactive inside existing controls/sections. ### Task T017 - Write token hook and prompt builder tests **Started**: 2026-06-09 16:51 **Completed**: 2026-06-09 16:58 **Duration**: 7 minutes **Notes**: * Added token hook coverage for success, malformed response, fetch failure, demo/offline disabled states, and abort cleanup. * Added prompt builder coverage for registry path insertion, graph path insertion, project wording, starter definitions, and forbidden unsafe text. **Files Changed**: * `src/hooks/__tests__/use-knowledge-graph-token.test.tsx` - Added token hook tests. * `src/lib/__tests__/knowledge-graph-connect-prompt.test.ts` - Added prompt builder and starter definition tests. **BQC Fixes**: * Failure path completeness: tests assert token failure states and abort cleanup. * Error information boundaries: prompt tests assert auth and direct mutation details are absent. ### Task T018 - Write ingest card behavior tests **Started**: 2026-06-09 16:58 **Completed**: 2026-06-09 17:08 **Duration**: 10 minutes **Notes**: * Added component tests for local path ingest, GitHub URL ingest, duplicate submit prevention, active graph remove, gate states, and close/reopen reset. * Test doubles assert the component calls `ingest.run` and `remove.run` rather than bridge endpoints. **Files Changed**: * `src/components/knowledge-graph/__tests__/knowledge-graph-ingest-card.test.tsx` - Added ingest card coverage. **BQC Fixes**: * Duplicate action prevention: tests assert repeated submit clicks call ingest once. * State freshness on re-entry: tests assert local form state resets after close/reopen. ### Task T019 - Write connect prompt, starter chip, and page composition tests **Started**: 2026-06-09 17:08 **Completed**: 2026-06-09 17:17 **Duration**: 9 minutes **Notes**: * Added connect prompt tests for expand/copy success, textarea fallback, redacted error text, and forbidden copied text. * Added starter chip tests for deterministic labels, repeated event dispatch, and optional chat-anchor scrolling. * Extended page tests with mocked token/admin hooks and composition assertions for ingest, prompt, and chips. **Files Changed**: * `src/components/knowledge-graph/__tests__/knowledge-graph-connect-prompt.test.tsx` - Added connect prompt tests. * `src/components/knowledge-graph/__tests__/knowledge-graph-starter-chips.test.tsx` - Added starter chip tests. * `src/components/knowledge-graph/__tests__/knowledge-graph-page.test.tsx` - Added token/admin mocks and composition assertions. **BQC Fixes**: * Failure path completeness: copy fallback and failure states are tested. * Contract alignment: page tests verify new components compose with existing fallback/read surface. ### Task T020 - Run focused tests and validate ASCII **Started**: 2026-06-09 17:17 **Completed**: 2026-06-09 17:22 **Duration**: 5 minutes **Notes**: * Ran the focused Session 06 Vitest command; 6 test files and 32 tests passed. * Ran `bun run typecheck`; TypeScript passed after correcting the clipboard mock signature. * Scanned all Session 06 source, test, task, and implementation-note files for non-ASCII characters; no findings. * No adjacent admin-hook expectation changes were required because UI tests verify component-to-hook contracts and existing admin-hook tests already cover graphify-missing and invalidation behavior. **Files Changed**: * `src/components/knowledge-graph/__tests__/knowledge-graph-connect-prompt.test.tsx` - Corrected clipboard mock typing found by typecheck. * `.spec_system/specs/phase26-session06-ingest-ui-connect-prompt-starter-chips/implementation-notes.md` - Logged verification results. * `.spec_system/specs/phase26-session06-ingest-ui-connect-prompt-starter-chips/tasks.md` - Marked final task and completion checklist. **BQC Fixes**: * Contract alignment: typecheck verified hook/component/test interfaces. * Accessibility and platform compliance: focused component tests verified accessible labels and button interactions. *** ## Verification * `bun run test -- src/hooks/__tests__/use-knowledge-graph-token.test.tsx src/lib/__tests__/knowledge-graph-connect-prompt.test.ts src/components/knowledge-graph/__tests__/knowledge-graph-ingest-card.test.tsx src/components/knowledge-graph/__tests__/knowledge-graph-connect-prompt.test.tsx src/components/knowledge-graph/__tests__/knowledge-graph-starter-chips.test.tsx src/components/knowledge-graph/__tests__/knowledge-graph-page.test.tsx` - Passed, 6 files / 32 tests. * `bun run typecheck` - Passed. * ASCII scan for Session 06 files - Passed. ### Task T002 - Inspect upstream Knowledge Graph UI behavior **Started**: 2026-06-09 16:09 **Completed**: 2026-06-09 16:10 **Duration**: 1 minute **Notes**: * Reviewed the Claude OS v2.4 reference route for ingest, mini stats, connect prompt, and starter chips. * Identified AI OS adaptations: remove direct component mutation fetches, replace tokenless script registration guidance, and dispatch starter events without importing chat. * Kept upstream review behavior-only; no upstream code was copied into the AI OS implementation. **Files Changed**: * `.spec_system/specs/phase26-session06-ingest-ui-connect-prompt-starter-chips/implementation-notes.md` - Logged upstream review. **BQC Fixes**: * Trust boundary: flagged upstream direct write instructions as unsafe for AI OS prompt adaptation. ### Task T003 - Confirm current Knowledge Graph page composition **Started**: 2026-06-09 16:10 **Completed**: 2026-06-09 16:11 **Duration**: 1 minute **Notes**: * Confirmed `KnowledgeGraphPage` composes hero, gallery, panel, and side rail from `useKnowledgeGraph`. * Confirmed existing page tests cover loaded, fallback, project selection, renderer callback, and selected-node behavior. * Confirmed the page has no write-capable UI before this session. **Files Changed**: * `.spec_system/specs/phase26-session06-ingest-ui-connect-prompt-starter-chips/implementation-notes.md` - Logged page baseline review. **BQC Fixes**: * None; inspection task only. --- # Agent Instructions This documentation is published with GitBook.
