**Notes**:

* Added MoA save constants, internal payload types, and `setup_required` bridge error-code support.
* Added exact-key validation for the root payload and nested aggregator/reference model objects.
* Added bounded validation for preset name, provider, model, one to three references, root temperatures, `max_tokens`, and optional `enabled`.

**Files Changed**:

* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Added MoA save invalid-payload tests and fixture helper.
* `scripts/lib/hermes-admin-bridge.ts` - Added the MoA save route scaffold used by route-level validation tests.

* The merge copies existing `moa` keys and existing `moa.presets`, then replaces only the named preset and `moa.default_preset`.
* Added route-level success coverage proving unrelated top-level config, unrelated MoA keys, and existing presets survive the save.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Added MoA preset merge helpers and handler merge call.

* Tightened temp-write cleanup so a temp-name collision does not remove a pre-existing file.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Added safe MoA save response and controlled write-failure behavior.
* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Added success response-shape and write-failure safety coverage.

**Verification**:

* Command/check: `bunx vitest run scripts/lib/__tests__/hermes-admin-bridge.test.ts`
  * Result: PASS - bridge tests pass with safe response and write-failure coverage.
  * Evidence: 1 test file passed, 54 tests passed.
* Command/check: BQC failure-path and error-boundary review

* Wired `savePreset` to POST `/__hermes_moa_save` with the MoA save request type and response parser.
* Added a dedicated `moaInFlightRef` and scoped mutation call for duplicate-trigger prevention while save is in flight.
* Invalidates Hermes model data after a successful save so later selector UI can refresh MoA presets.

**Files Changed**:

* `src/hooks/use-hermes-admin.ts` - Added MoA save imports, action interface, mutation, in-flight guard, and hook result group.

**Verification**:

* Command/check: `bunx vitest run src/hooks/__tests__/use-hermes-admin.test.tsx`
  * Result: PASS - existing hook behavior still passes after the new action group.
  * Evidence: 1 test file passed, 35 tests passed.
* Command/check: BQC duplicate action and contract alignment review
  * Result: PASS - MoA save has its own in-flight ref, mutation view, typed request, response parser, and query invalidation on success.

## Post-Completion Verification

### 2026-07-03 02:18 - Formatting And Final Checks

**Notes**:

* Ran Prettier on touched source and test files. It reformatted `scripts/lib/hermes-admin-bridge.ts` and `scripts/lib/__tests__/hermes-admin-bridge.test.ts`; other touched files were unchanged.
* Re-ran the focused suite, typechecks, diff whitespace check, and ASCII/CRLF scan after formatting.

**Verification**:

* Command/check: `bunx prettier --write scripts/lib/hermes-admin-bridge.ts scripts/lib/__tests__/hermes-admin-bridge.test.ts src/lib/hermes-admin-types.ts src/lib/__tests__/hermes-admin-types.test.ts src/hooks/use-hermes-admin.ts src/hooks/__tests__/use-hermes-admin.test.tsx src/components/hermes/__tests__/hermes-documents-gallery.test.tsx src/components/hermes/__tests__/hermes-mission-control.test.tsx src/components/hermes/__tests__/hermes-sections.test.tsx src/components/hermes/chat/__tests__/hermes-chat-tab.test.tsx src/components/hermes/intelligence/__tests__/intelligence-portal.test.tsx src/components/knowledge-graph/__tests__/knowledge-graph-grounded-chat.test.tsx`
  * Result: PASS - formatting completed successfully.
  * Evidence: Prettier exited with code 0.
* Command/check: `bunx vitest run scripts/lib/__tests__/hermes-admin-bridge.test.ts src/lib/__tests__/hermes-admin-types.test.ts src/hooks/__tests__/use-hermes-admin.test.tsx`
  * Result: PASS - focused suite still passes after formatting.
  * Evidence: 3 test files passed, 101 tests passed.
* Command/check: `bun run typecheck:scripts && bun run typecheck`
  * Result: PASS - script and app typechecks still pass after formatting.
  * Evidence: both TypeScript commands exited with code 0.
* Command/check: `git diff --check`
  * Result: PASS - no whitespace errors reported.
  * Evidence: command exited with code 0 and no output.
* Command/check: `rg -n --pcre2 '[^\\x00-\\x7F]|\\r' [changed source/test/session files] || true`
  * Result: PASS - no non-ASCII or CRLF matches in changed files.
  * Evidence: command produced no matches.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase40-session06-moa-save-endpoint/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
