***

### Task T014 - Normalize existing mission store records during admin reads

**Started**: 2026-06-08 14:13 **Completed**: 2026-06-08 14:18 **Duration**: 5 minutes

**Notes**:

* Added tolerant admin-side normalization for stored mission documents and goals.
* Existing stores are normalized to include `schema_version`, bounded mission/goal counts, safe dates, optional text fallbacks, and queued fallback statuses.
* Because create, commit, tick, and clear all read the store before writing, the next authorized write persists upgraded shapes through `writeAtomicJson`.

* Failure path completeness: malformed archived records are skipped without breaking valid mission writes.
* Contract alignment: upgraded stores persist the versioned mission document shape.

***

### Task T013 - Write schema\_version on admin mission documents

**Started**: 2026-06-08 14:11 **Completed**: 2026-06-08 14:13 **Duration**: 2 minutes

**Notes**:

* Added `schema_version` to `HermesMissionDocument`.
* Set the field in `createMissionDocument`, which is shared by create, optimize preview, and commit.

**Files Changed**:

* `scripts/lib/hermes-admin-bridge.ts` - added admin mission schema version output.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T013 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded admin version output update.

**BQC Fixes**:

* Contract alignment: all admin mission write and preview responses now include the declared current schema version.
* Trust boundary enforcement: version stamping remains inside the existing loopback, token, and admin-gated bridge boundary.

***

### Task T011 - Add read-bridge coverage for v2.3-shaped stores

**Started**: 2026-06-08 14:07 **Completed**: 2026-06-08 14:11 **Duration**: 4 minutes

**Notes**:

* Added a focused read-bridge test for v2.3-shaped local mission stores without `schema_version`.
* Verified optional `done_when`, `full_prompt`, and `estimate` fields upgrade to empty strings and unknown v2.3 status values normalize to `queued`.

**Files Changed**:

* `scripts/lib/__tests__/hermes-dev-bridge.test.ts` - added legacy/v2.3 mission normalization coverage.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T011 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded coverage update.

**BQC Fixes**:

* Contract alignment: test coverage now verifies the tolerant bridge output satisfies the strict browser mission contract.

***

### Task T012 - Add read-bridge malformed and sanitized output coverage

**Started**: 2026-06-08 14:07 **Completed**: 2026-06-08 14:11 **Duration**: 4 minutes

**Notes**:

* Added read-bridge coverage for malformed archived entries, invalid active pointers, deterministic mission ordering, unknown statuses, and email redaction in mission prompts.

**Files Changed**:

* `scripts/lib/__tests__/hermes-dev-bridge.test.ts` - added malformed and sanitized mission output coverage.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T012 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded coverage update.

**BQC Fixes**:

* Failure path completeness: tests prove malformed entries do not break valid mission projection.
* Error information boundaries: tests prove sensitive email-like values are redacted from browser-visible mission output.

***

### Task T010 - Harden read-side mission store normalization

**Started**: 2026-06-08 14:04 **Completed**: 2026-06-08 14:07 **Duration**: 3 minutes

**Notes**:

* Added read-side mission store helpers for record detection, bounded normalized lists, and post-normalization active pointer validation.
* Changed count limiting so malformed local mission entries are skipped before the `MAX_MISSION_COUNT` cap is consumed.
* Added a bridge comment documenting that AI OS accepts v2.3-shaped stores but exposes the richer AI OS browser envelope.

**Files Changed**:

* `scripts/lib/hermes-dev-bridge.ts` - hardened mission list and active pointer normalization.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T010 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded store normalization update.

**BQC Fixes**:

* Failure path completeness: malformed archived entries are contained without aborting valid mission projection.
* Contract alignment: invalid active pointers become `active: null` and `mission: null` after valid summaries are preserved.

***

### Task T009 - Harden read-side mission goal normalization

**Started**: 2026-06-08 14:02 **Completed**: 2026-06-08 14:04 **Duration**: 2 minutes

**Notes**:

* Added explicit read-side helpers for mission actor, goal status, and optional text normalization.
* Missing `done_when`, `full_prompt`, and `estimate` normalize to empty strings; unknown statuses normalize to `queued`.

**Files Changed**:

* `scripts/lib/hermes-dev-bridge.ts` - added explicit goal normalization helpers.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T009 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded normalization update.

**BQC Fixes**:

* Failure path completeness: malformed optional goal fields are normalized to safe browser-visible fallbacks instead of leaking bad states.
* Contract alignment: unknown local statuses are contained before reaching strict client parsers.

* Added a Hermes Mission Control Contract section to `docs/data-contract.md`.
* Documented the AI OS `{ ok, active, mission, total, missions }` browser envelope, `schema_version: 1`, legacy in-memory upgrades, next-write persistence, and raw v2.3 `{ mission }` incompatibility.

**Files Changed**:

* `docs/data-contract.md` - documented mission version and envelope contract.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/tasks.md` - marked T008 complete.
* `.spec_system/specs/phase25-session02-mission-schema-version-legacy-compatibility/implementation-notes.md` - recorded documentation update.

**BQC Fixes**:

* Contract alignment: documentation now matches the typed AI OS mission envelope instead of raw v2.3 endpoint output.

***

## 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/phase25-session02-mission-schema-version-legacy-compatibility/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.
