**Started**: 2026-07-03 01:06 **Completed**: 2026-07-03 01:07 **Duration**: 1 minute

**Notes**:

* Established a clean focused test baseline before command endpoint edits.
* The focused suite already covers sanitizer, bridge, parser, and admin hook behavior around the files this session will modify.

**Files Changed**:

* `.spec_system/specs/phase40-session05-command-endpoint/implementation-notes.md` - Recorded baseline test evidence.
* `.spec_system/specs/phase40-session05-command-endpoint/tasks.md` - Marked T002 complete.

### Task T003 - Inspect admin bridge endpoint registration, resolver, executor, hook, parser, and sanitizer owners

**Started**: 2026-07-03 01:07 **Completed**: 2026-07-03 01:09 **Duration**: 2 minutes

**Notes**:

* Confirmed `ENDPOINTS` in `scripts/lib/hermes-admin-bridge.ts` is the bridge-local route registry that Vite consumes through `registerHermesAdminBridge()`.
* Confirmed `resolveHermesCommand()` is currently chat-specific because both source-entrypoint and wrapper fallback prefixes include `chat`.
* Confirmed `executeCommand()` already uses non-shell `spawn()`, bounded stdout/stderr buffers, timeouts, inherited Python env cleanup, and shared `sanitizeBridgeOutput()`.
* Confirmed `src/lib/hermes-admin-types.ts` owns parser contracts and `src/hooks/use-hermes-admin.ts` owns admin mutation views and duplicate in-flight guards.
* Confirmed `scripts/lib/sanitize.ts` already preserves safe provider/model words and redacts command-like unsafe output, so sanitizer edits should be fixture-driven only.

**Files Changed**:

* `.spec_system/specs/phase40-session05-command-endpoint/implementation-notes.md` - Recorded owner inspection evidence.
* `.spec_system/specs/phase40-session05-command-endpoint/tasks.md` - Marked T003 complete.

**Verification**:

* Command/check: `rg -n "ENDPOINTS|resolveHermesCommand|executeCommand|__hermes_chat|sanitizeBridgeOutput|readJsonBody|assertAdmin|registerHermesAdminBridge|spawn" scripts/lib/hermes-admin-bridge.ts`
  * Result: PASS - Located route registry, body parser, resolver, executor, chat handler, and bridge registration.
  * Evidence: `ENDPOINTS` at line 365, `resolveHermesCommand()` at line 995, `executeCommand()` at line 1111, `registerHermesAdminBridge()` at line 2501.
* Command/check: `sed -n '960,1170p' scripts/lib/hermes-admin-bridge.ts`
  * Result: PASS - Resolver/executor ownership inspected.
  * Evidence: Resolver hard-codes `chat`; executor sanitizes stdout/stderr and supports timeout/output caps.
* Command/check: `sed -n '260,980p' src/hooks/use-hermes-admin.ts` and `sed -n '260,980p' src/lib/hermes-admin-types.ts`
  * Result: PASS - Hook and parser ownership inspected.
  * Evidence: Hook has scoped mutation guard helpers; parser has record/string/boolean/number readers and response parser pattern.
* Command/check: `sed -n '1,620p' scripts/lib/__tests__/hermes-admin-bridge.test.ts`, `sed -n '1,620p' src/hooks/__tests__/use-hermes-admin.test.tsx`, and matching parser/sanitizer test reads
  * Result: PASS - Existing focused test patterns inspected before edits.
  * Evidence: Bridge tests use `createRoutes()` and captured spawn; hook tests use `renderHook()`, mocked fetch, and mutation state checks.
* UI product-surface check: N/A - Owner inspection only; no user-facing route changed.
* UI craft check: N/A - Owner inspection only; no visual UI changed.

  * Result: PASS - Existing parser suite still passes after adding command contracts.
  * Evidence: 1 test file passed; 6 tests passed.
* Command/check: Targeted inspection of `src/lib/hermes-admin-types.ts`
  * Result: PASS - Parser rejects malformed response shape and unknown command names through `HermesAdminParseError`.
  * Evidence: `readHermesCommandName()` and `parseHermesCommandResponse()` added beside existing parser helpers.
* UI product-surface check: N/A - Parser/type contract only; no user-facing route changed.
* UI craft check: N/A - Parser/type contract only; no visual UI changed.

**Started**: 2026-07-03 01:11 **Completed**: 2026-07-03 01:12 **Duration**: 1 minute

**Notes**:

* Added bridge-local command metadata for `version`, `status`, `insights --days 30`, `doctor`, and `update --yes`.
* Added per-command labels and timeouts of 20s, 25s, 30s, 60s, and 300s.
* Added `readHermesCommandDefinition()` to reject unknown commands before spawn and require explicit `update` confirmation.
* Added command failure response helpers that keep details inside sanitized JSON error arrays.
* BQC: Trust boundary enforcement and failure path completeness are covered by explicit schema checks and controlled error mapping before process execution.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Added command allowlist metadata, request parsing, confirmation enforcement, and command error helpers.

### Task T007 - Refactor Hermes source-entrypoint and CLI fallback resolution

**Started**: 2026-07-03 01:11 **Completed**: 2026-07-03 01:13 **Duration**: 2 minutes

**Notes**:

* Refactored `resolveHermesCommand()` to accept a subcommand while defaulting to `chat`.
* Source-entrypoint resolution now returns `[main.py, subcommand]`; wrapper and detected CLI fallback return `[subcommand]`.
* Existing chat and mission optimize callers still use the default `chat` prefix, preserving prior argv ordering.
* BQC: Contract alignment verified by keeping a default compatible resolver signature and running existing bridge argv tests.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Made Hermes resolution subcommand-aware without changing current chat call sites.
* `.spec_system/specs/phase40-session05-command-endpoint/implementation-notes.md` - Recorded task evidence.

  * Evidence: 1 test file passed; 44 tests passed.
* Command/check: Targeted inspection of `scripts/lib/hermes-admin-bridge.ts`
  * Result: PASS - `resolveHermesCommand(options, subcommand = "chat")` uses the selected subcommand for source and wrapper paths.
  * Evidence: Source prefix is `[sourceMain, subcommand]`; wrapper prefix is `[subcommand]`.
* UI product-surface check: N/A - Resolver/backend contract only; no visible command menu added.
* UI craft check: N/A - Resolver/backend contract only; no visual UI changed.

***

### Task T008 - Add command-output sanitizer fixtures

**Started**: 2026-07-03 01:13 **Completed**: 2026-07-03 01:14 **Duration**: 1 minute

**Notes**:

* Added command-output fixtures for ANSI stripping, home-path redaction, email redaction, bridge ID redaction, key-value secret redaction, and bearer redaction.
* Added negative coverage that preserves safe Hermes command words, provider slugs, model IDs, and normal status prose.
* No `scripts/lib/sanitize.ts` production change was needed because the existing shared sanitizer passed the new fixtures.
* BQC: Error information boundaries verified for command-output-shaped strings without broadening false positives.

**Files Changed**:

* `scripts/lib/__tests__/sanitize.test.ts` - Added command-output redaction and safe negative fixtures.
* `.spec_system/specs/phase40-session05-command-endpoint/implementation-notes.md` - Recorded task evidence.

### Task T009 - Register POST `/__hermes_cmd` with bridge gates

**Started**: 2026-07-03 01:14 **Completed**: 2026-07-03 01:18 **Duration**: 4 minutes

**Notes**:

* Registered `/__hermes_cmd` in the bridge-local `ENDPOINTS` list.
* The handler uses existing `requirePreflight()` with `POST` and admin mode required, preserving method, loopback/Host, token, and admin gates.
* JSON body parsing remains behind preflight and uses the existing body-size bounded `readJsonBody()`.
* BQC: Trust boundary enforcement remains at the bridge boundary before JSON parsing and before spawn.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Added `/__hermes_cmd` endpoint registration and handler preflight.
* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Added command endpoint gate coverage and route inventory coverage.

* UI product-surface check: N/A - Endpoint-only change; no command menu or visible UI added.
* UI craft check: N/A - Endpoint-only change; no visual UI changed.

***

### Task T010 - Implement command request parsing and `update` confirmation

**Started**: 2026-07-03 01:14 **Completed**: 2026-07-03 01:19 **Duration**: 5 minutes

**Notes**:

* Added schema-style parsing for an object payload with an allowlisted `command` field.
* Unknown command names return `invalid_payload` before resolving or spawning Hermes.
* `update` requires explicit confirmation through the existing confirmation helper and maps missing confirmation to `conflict`.
* BQC: Trust boundary enforcement and mutation safety verified by rejecting non-allowlisted input and requiring confirmation for the mutating command.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Added command payload parser and confirmation check.
* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Added invalid JSON, unknown command, and missing update confirmation coverage.

### Task T011 - Execute allowed Hermes commands through argv arrays, safe env, caps, and timeouts

**Started**: 2026-07-03 01:14 **Completed**: 2026-07-03 01:20 **Duration**: 6 minutes

**Notes**:

* Command handler resolves Hermes by subcommand and invokes `executeCommand()` with explicit argv arrays.
* Added terminal-safe command env flags while preserving inherited Python env stripping through `createSpawnEnv()`.
* Execution uses existing output caps and per-command timeouts from allowlist metadata.
* BQC: External dependency resilience verified by timeout-bounded process execution; trust boundary enforcement verified by no shell option and exact argv assertions.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Wired command execution through the existing non-shell executor with command env and timeout metadata.
* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Added source-entrypoint argv, CLI fallback argv, env cleanup, timeout, and `update --yes` coverage.

### Task T012 - Map command success and failure results to sanitized JSON

**Started**: 2026-07-03 01:14 **Completed**: 2026-07-03 01:21 **Duration**: 7 minutes

**Notes**:

* Successful commands return typed JSON with `ok`, `command`, `label`, `code`, `timedOut: false`, `stdout`, and `stderr`.
* Timeouts return `ok: false`, `code: "timeout"`, status 504, and do not expose command success fields.
* Non-zero exits return controlled `internal_error` responses with sanitized detail strings.
* Missing binary and spawn failure return controlled `hermes_unavailable` responses.
* BQC: Failure path completeness and error information boundaries verified across timeout, non-zero, missing binary, and spawn failure paths.

**Files Changed**:

* Command/check: Targeted inspection of command timeout and non-zero tests
  * Result: PASS - Timeout response is `ok: false`, has no `command` success field, kills with `SIGTERM`, and redacts partial stdout.
  * Evidence: Non-zero detail tests redact `/home/alice`, account IDs, and secret values in `errors`.
* UI product-surface check: N/A - Endpoint-only change; no command menu or visible UI added.
* UI craft check: N/A - Endpoint-only change; no visual UI changed.

### Task T015 - Preserve existing admin behavior after endpoint and resolver changes

**Started**: 2026-07-03 01:21 **Completed**: 2026-07-03 01:24 **Duration**: 3 minutes

**Notes**:

* Existing chat, mission, Pantheon, document, image, and Obsidian admin behavior remains covered by the focused bridge and hook suites.
* The command resolver defaults to `chat`, so current chat and mission optimize call sites preserve prior argv construction.
* No direct `vite.config.ts` route-specific middleware was added; the bridge-local registration pattern remains intact.
* BQC: Contract alignment verified by the full focused suite spanning bridge runtime behavior, parser contracts, sanitizer behavior, and hook state.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - Kept existing bridge registration pattern and default chat resolver behavior.
* `scripts/lib/__tests__/hermes-admin-bridge.test.ts` - Existing admin behavior regression coverage remains passing with command endpoint added.

## 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-session05-command-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.
