expanded demo fixture parses and exposes no local configured providers. * Evidence: Output showed default `openai/gpt-5.5`, 3 catalog groups, 1 safe mixture, and `configured: 0`. * Command/check: Demo fixture leakage regex over serialized parsed payload. * Result: PASS - no private path, auth JSON, `.env`, or `sk-` token-shaped substring was present. * Evidence: The command would throw on a match and exited 0. * UI product-surface check: N/A - no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. *** ### Task T007 - Preserve useHermes model query empty-state and demo behavior after parser normalization **Started**: 2026-07-02 21:14 **Completed**: 2026-07-02 21:15 **Duration**: 1 minute **Notes**: * Reviewed `useHermes` model query behavior after parser normalization. * No hook code changes were required because `parseHermesModelsResponse` returns the stable normalized `HermesModelsBody` shape. * Existing hook empty-state checks still use `catalog` model counts, preserving prior behavior. **Files Changed**: * `.spec_system/specs/phase40-session02-models-and-provider-readiness/implementation-notes.md` - Recorded T007 evidence. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/tasks.md` - Marked T007 complete after evidence was recorded. **Verification**: * Command/check: `bunx vitest run src/hooks/__tests__/use-hermes.test.tsx` * Result: PASS - hook behavior remained stable with the expanded parser shape. * Evidence: Vitest reported 1 test file passed and 12 tests passed. * Command/check: Manual BQC contract alignment review. * Result: PASS - model query consumers continue to receive one normalized response shape and do not branch on old versus upstream body variants. * Evidence: `src/hooks/use-hermes.ts` still fetches `/__hermes_models` through `parseHermesModelsResponse` and computes empty state from `data.catalog`. * UI product-surface check: N/A - no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. *** ### Task T008 - Add safe Hermes config helpers for MoA mixture discovery with malformed/missing config fail-soft behavior **Started**: 2026-07-02 21:15 **Completed**: 2026-07-02 21:19 **Duration**: 4 minutes **Notes**: * Added bounded YAML parsing for Hermes `config.yaml` using the existing `js-yaml` dependency. * Added safe MoA preset discovery from `moa.presets` with deterministic sorting and a fixed maximum row count. * Missing and malformed config now return a valid expanded model body with empty `mixtures` and `configured` arrays. **Files Changed**: * `scripts/lib/hermes-dev-bridge.ts` - Added config parsing helpers and safe MoA mixture projection. * `scripts/lib/__tests__/hermes-dev-bridge.test.ts` - Added missing/malformed config and MoA discovery coverage. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/implementation-notes.md` -

no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. *** ### Task T009 - Add configured-provider derivation from default provider, auth JSON provider keys, Hermes .env, config providers, and readiness classification **Started**: 2026-07-02 21:15 **Completed**: 2026-07-02 21:19 **Duration**: 4 minutes **Notes**: * Configured providers are derived from the default provider, readiness slug, auth JSON provider keys, Hermes `.env` API-key presence, and `providers:` entries in config YAML. * Provider aliases are expanded before output so retained AI OS and upstream provider IDs can both match catalog groups. * Env values and auth JSON payload values are never emitted; only safe provider slugs are returned. **Files Changed**: * `scripts/lib/hermes-dev-bridge.ts` - Added configured-provider derivation helpers and model endpoint wiring. * `scripts/lib/hermes-provider-readiness.ts` - Added provider alias/key helper exports consumed by the bridge. * `scripts/lib/__tests__/hermes-dev-bridge.test.ts` - Added configured-provider derivation assertions. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/implementation-notes.md` - Recorded T009 evidence. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/tasks.md` -

focused parser, bridge, and hook checks passed. * Evidence: Vitest reported 3 test files passed and 39 tests passed. * UI product-surface check: N/A - no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. *** ### Task T017 - Run TypeScript gates for app and scripts **Started**: 2026-07-02 21:23 **Completed**: 2026-07-02 21:25 **Duration**: 2 minutes **Notes**: * Initial TypeScript gate run found two contract follow-ups: a readonly tuple `includes` typing issue in provider readiness and a legacy component test fixture missing the expanded model body fields. * Fixed both issues and reran the app and script TypeScript gates successfully. **Files Changed**: * `scripts/lib/hermes-provider-readiness.ts` - Fixed provider env-key lookup typing for readonly key arrays. * `src/components/hermes/__tests__/hermes-sections.test.tsx` - Updated Hermes component model fixture to the expanded model body shape. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/implementation-notes.md` - Recorded T017 typecheck evidence. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/tasks.md` - Marked T017 complete after evidence was recorded. **Verification**: * Command/check: `bun run typecheck && bun run typecheck:scripts` * Result: PASS after fixes - app and script TypeScript gates passed. * Evidence: Final output ran `tsc --noEmit` and `tsc --noEmit -p tsconfig.scripts.json` with exit code 0. * Command/check: `bunx prettier --write scripts/lib/hermes-provider-readiness.ts src/components/hermes/__tests__/hermes-sections.test.tsx` * Result: PASS - touched files were formatted. * Evidence: Prettier reported both files unchanged after formatting. * UI product-surface check: N/A - no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. **BQC Fixes**: * Contract alignment: Updated a remaining typed component fixture so the expanded model contract is represented consistently in component tests (`src/components/hermes/__tests__/hermes-sections.test.tsx`). *** ### Task T018 - Validate ASCII, LF line endings, diff whitespace, and session artifact completeness **Started**: 2026-07-02 21:25 **Completed**: 2026-07-02 21:27 **Duration**: 2 minutes **Notes**: * ASCII check passed over touched source, test, and Session 02 spec-system files. * LF/no-CR check passed over touched source, test, and Session 02 spec-system files. * Tracked diff whitespace check passed. * Untracked session artifact whitespace check passed for Session 02 artifacts. * Task checklist shows all 18 tasks complete before the completion checklist update. * Current tracked diff is scoped to Session 02 artifacts and Hermes model/readiness source and test files. **Files Changed**: * `.spec_system/specs/phase40-session02-models-and-provider-readiness/implementation-notes.md` - Recorded T018 final artifact checks. * `.spec_system/specs/phase40-session02-models-and-provider-readiness/tasks.md` - Marked T018 and the completion checklist complete after evidence was recorded. **Verification**: * Command/check: `rg --pcre2 -n "[^\\x00-\\x7F]" src/lib/hermes-types.ts src/lib/hermes-demo-data.ts src/hooks/__tests__/use-hermes.test.tsx scripts/lib/hermes-provider-readiness.ts scripts/lib/hermes-dev-bridge.ts scripts/lib/__tests__/hermes-dev-bridge.test.ts src/lib/__tests__/hermes-types.test.ts src/components/hermes/__tests__/hermes-sections.test.tsx .spec_system/specs/phase40-session02-models-and-provider-readiness` * Result: PASS - no non-ASCII characters found. * Evidence: Command produced no output. * Command/check: `rg -n $'\\r' src/lib/hermes-types.ts src/lib/hermes-demo-data.ts src/hooks/__tests__/use-hermes.test.tsx scripts/lib/hermes-provider-readiness.ts scripts/lib/hermes-dev-bridge.ts scripts/lib/__tests__/hermes-dev-bridge.test.ts src/lib/__tests__/hermes-types.test.ts src/components/hermes/__tests__/hermes-sections.test.tsx .spec_system/specs/phase40-session02-models-and-provider-readiness` * Result: PASS - no carriage-return characters found. * Evidence: Command produced no output. * Command/check: `git diff --check` * Result: PASS - tracked diff whitespace check passed. * Evidence: Command produced no output and exited 0. * Command/check: `git diff --no-index --check /dev/null ` * Result: PASS - untracked session artifact whitespace check passed. * Evidence: Output reported `untracked_session_artifact_whitespace=pass`. * Command/check: `git diff --name-status` * Result: PASS - tracked diff scope captured. * Evidence: Output listed Session 02 artifacts, Hermes bridge/readiness source, parser/hook/component fixtures, and focused tests. * Command/check: `sed -n '1,220p' .spec_system/specs/phase40-session02-models-and-provider-readiness/tasks.md` * Result: PASS - task checklist completeness reviewed. * Evidence: Output showed T001 through T017 checked with only T018 remaining before this final update. * UI product-surface check: N/A - no route, component, or route-visible UI changed. * UI craft check: N/A - no UI changed. *** --- # Agent Instructions This documentation is published with GitBook.
