 # Email Ownership Tracker
 
-This folder is the isolated workspace for the Email Ownership Tracker tool.
+Email Ownership Tracker is an isolated V1 team workspace for reviewing who owns
+email threads, when ownership changed, and which handoffs still need team
+attention. It is not wired into the main app yet.
 
 ## Ownership Boundary
 
 All work for this tool must stay inside:
 
-`text
-.\tools\v1\team\email-ownership-tracker\
-`
+```text
+tools/v1/team/email-ownership-tracker/
+```
 
 Do not wire this tool into the main app, routing, inbox architecture, wallet core, Stellar core, database schema, or existing design system unless a future integration issue explicitly allows it.
 
-See specs.md for the issue categories and contributor expectations.
+## Reviewer Setup
+
+This issue adds folder-local documentation, synthetic fixtures, and a
+zero-dependency Node contract test. Run from the repository root:
+
+```bash
+node --test tools/v1/team/email-ownership-tracker/tests/email-ownership-docs.test.mjs
+```
+
+The test validates the local fixture and documentation contract without using
+main app test helpers.
+
+## Documentation Map
+
+- `specs.md` defines the ownership review model and contributor boundary.
+- `docs/test-plan.md` lists automated and manual review checks.
+- `docs/review-notes.md` summarizes reviewer expectations and limitations.
+- `fixtures/ownership-review-cases.json` provides synthetic ownership scenarios.
+- `tests/email-ownership-docs.test.mjs` validates the fixture and documentation
+  contract.
+
+## Current Limitations
+
+- No inbox ingestion, mailbox mutation, team assignment write, notification, or
+  database persistence is included.
+- No app routing, dashboard registration, wallet, Stellar, auth, or shared
+  design-system integration is included.
+- Fixture content is synthetic and should remain folder-local.

+# Email Ownership Tracker Review Notes
+
+## What This Contribution Covers
+
+This contribution adds contributor-facing documentation and fixture coverage for
+the isolated Email Ownership Tracker folder. It gives reviewers a local
+validation path without connecting to production inbox data, assignment systems,
+or the main application.
+
+Reviewers should expect:
+
+- a repaired README and specs file for the folder-local workflow.
+- a deterministic synthetic fixture with representative ownership statuses.
+- a local Node test that validates fixture and documentation requirements.
+- clear limitations for future inbox, notification, assignment, and persistence
+  work.
+
+## What Is Out Of Scope
+
+This issue does not add:
+
+- inbox reads, mailbox writes, or mail rendering changes.
+- owner assignment side effects or notification delivery.
+- database schema changes or persistence.
+- app routing, dashboard placement, authentication, wallet, Stellar, or shared
+  design-system changes.
+- production sender, recipient, mailbox, customer, or teammate data.
+
+## Reviewer Flow
+
+1. Run the local Node test from the repository root.
+2. Inspect `fixtures/ownership-review-cases.json` and confirm all cases are
+   synthetic.
+3. Compare fixture statuses with the rules in `specs.md`.
+4. Confirm `docs/test-plan.md` names both current checks and future coverage
+   gaps.
+5. Confirm the PR changes only files inside this tool folder.
+
+## Known Limitations
+
+The fixture documents the review contract before this folder has production
+assignment behavior. A future feature issue should implement ownership state
+logic inside this folder first; main app integration should remain a separate
+follow-up after the isolated model is accepted.

+# Email Ownership Tracker Test Plan
+
+## Automated Checks
+
+Run from the repository root:
+
+```bash
+node --test tools/v1/team/email-ownership-tracker/tests/email-ownership-docs.test.mjs
+```
+
+The local test checks that:
+
+- synthetic fixture cases use stable identifiers and contain no production data.
+- all documented ownership statuses are represented.
+- unowned threads are classified as `needs-owner`.
+- transfer cases include both current and previous owners.
+- stale cases require review and include an age-based signal.
+- documentation includes setup, fixture, limitation, and review guidance.
+
+## Manual Review Checklist
+
+- Confirm all changed files stay under `tools/v1/team/email-ownership-tracker/`.
+- Confirm fixture content is synthetic and avoids real sender, recipient,
+  customer, mailbox, or teammate data.
+- Confirm the status rules in `specs.md` match the fixture vocabulary.
+- Confirm no live network calls, secrets, database writes, assignment writes,
+  notifications, inbox writes, wallet behavior, Stellar behavior, or app routing
+  changes are introduced.
+- Confirm future integration boundaries are documented instead of implemented.
+
+## Future Code Coverage
+
+When folder-local service or UI code is added, extend coverage for:
+
+- owner assignment and reassignment transitions.
+- stale ownership thresholds.
+- empty, loading, error, and success states.
+- duplicate owner changes and missing-owner warnings.
+- audit history ordering and reviewer notes.
+
+Keep future tests folder-local unless a separate integration issue explicitly
+allows app-wide coverage.

-# Email Ownership Tracker Specs
+## Fixture Contract
 
-## Purpose
+Synthetic ownership cases should include:
 
-Track ownership history.
+- `id`: stable fixture-local identifier.
+- `threadId`: synthetic email thread identifier.
+- `subject`: synthetic thread subject.
+- `currentOwner`: assigned team member or an empty string when unowned.
+- `previousOwner`: previous team member or null.
+- `department`: team responsible for the current next step.
+- `lastChangedAt`: ISO timestamp for the latest ownership change.
+- `ageHours`: hours since the latest ownership update.
+- `signals`: local reasons for the ownership status.
+- `ownershipStatus`: `owned`, `needs-owner`, `transfer-pending`, or `stale`.
+- `reviewRequired`: true unless ownership is healthy.
+- `nextAction`: reviewable guidance for the team.
+- `containsProductionData`: false for all local fixtures.
 
-## Contributor boundary
+## Status Rules
+
+- `owned`: a named owner is attached and the thread is recent.
+- `needs-owner`: no owner is assigned.
+- `transfer-pending`: ownership is being handed from one teammate to another.
+- `stale`: a named owner exists, but ownership has not changed recently enough.
+
+## Contributor Boundary
 
 All work for this tool should stay in:
 
-$dir/
+```text
+tools/v1/team/email-ownership-tracker/
+```
+
+Do not add inbox writes, mailbox mutations, assignment side effects,
+notifications, database persistence, app routes, wallet behavior, Stellar
+behavior, auth changes, or shared design system changes in this issue.
