feat(07.1): session revocation on privilege change — CR-01/CR-02/CR-03

- revoke_all_refresh_tokens: add skip_token_hash optional param (exclude
  current session while revoking others)
- change_password, enable_totp, disable_totp: call revoke with skip hash
  derived from refresh cookie; return sessions_revoked in response and
  write to audit log metadata_
- 3 new tests: test_{change_password,enable_totp,disable_totp}_revokes_other_sessions
  — all PASSED; 373 total passing, 0 regressions
- Frontend toasts: SettingsAccountTab + TotpEnrollment show
  "Other sessions have been terminated." when sessions_revoked > 0
- Companion fixes: rate_limiting get_client_ip refactor, deps/auth.py
  request.state.current_user, locustfile refresh-token task removal
- Version bump: 0.1.0 → 0.1.1

+# Plan 07.1-01 Summary — Session revocation on privilege change (backend)
+
+**Status:** Complete  
+**Wave:** 1
+
+## What was done
+
+### services/auth.py
+- Extended `revoke_all_refresh_tokens` signature: added `skip_token_hash: Optional[str] = None`
+- When `skip_token_hash` is set, the WHERE clause excludes that token (`RefreshToken.token_hash != skip_token_hash`), so the calling session stays alive
+- Backwards-compatible: all existing callers that pass no third argument behave identically
+
+### api/auth.py
+- `change_password`: derives skip hash from refresh cookie → calls `revoke_all_refresh_tokens` with skip → extends audit log `metadata_` with `sessions_revoked` → returns `{"message": "Password updated", "sessions_revoked": revoked}`
+- `enable_totp`: same pattern → returns `{"backup_codes": plain_codes, "sessions_revoked": revoked}`
+- `disable_totp`: same pattern → returns `{"message": "TOTP disabled", "sessions_revoked": revoked}`
+- `logout_all` handler: unchanged (intentionally revokes all sessions without skip)
+
+## Verification
+
+```

+
+**Status:** Complete  
+**Wave:** 2
+
+## What was done
+
+### backend/tests/test_auth_api.py
+- Added `RefreshToken` to imports from `db.models`
+- Appended 3 new `@pytest.mark.asyncio` tests:
+  - `test_change_password_revokes_other_sessions`: inserts a second RefreshToken, calls change-password, asserts `sessions_revoked >= 1` and the row is revoked
+  - `test_enable_totp_revokes_other_sessions`: same pattern for totp/enable (mocks `verify_totp` and `store_backup_codes`)
+  - `test_disable_totp_revokes_other_sessions`: same pattern for DELETE /api/auth/totp
+
+### frontend/src/components/settings/SettingsAccountTab.vue
+- Added `sessionRevokedToast = ref(false)`
+- Added a fixed top-right toast (same visual pattern as SettingsView OAuth toast)
+- `changePassword()`: captures API response, shows toast for 5s when `sessions_revoked > 0`
+- `disableTotp()`: captures API response, shows toast for 5s when `sessions_revoked > 0`
+
+### frontend/src/components/auth/TotpEnrollment.vue
+- Added `sessionRevokedToast = ref(false)`
+- Added an inline (non-fixed) alert block at the top of the component template
+- `confirmEnrollment()`: checks `data.sessions_revoked > 0` and shows the inline alert for 5s

 ```
 
+---
+
+## Documentation Protocol (Non-Negotiable)
+
+Every major development step — completing a plan, fixing a significant bug, or shipping a new feature — must end with documentation and a commit. "Major step" means any plan execution (`/gsd:execute-phase`) or standalone feature work that changes user-facing behaviour, the API surface, environment variables, or the architectural rules.
+
+### After completing each plan or phase
+
+1. **Update `CLAUDE.md`** (this file):
+   - Update the "Current state" line in the GSD Workflow section to reflect what was just completed.
+   - Update the shared module map if new shared helpers were introduced.
+   - Update the code standards if new non-negotiable rules were established.
+
+2. **Update `README.md`** if any of the following changed:
+   - New user-facing features (add to the Features section).
+   - New or changed environment variables (update the env var table).
+   - New cloud storage backend, AI provider, or API endpoint group.
+   - Changed service URLs, port numbers, or startup procedure.
+   - Changed version number (`backend/main.py` and `frontend/package.json` are the sources of truth).
+
+3. **Version bump rule**: increment the patch segment of the version in `backend/main.py` and `frontend/package.json` after every plan that ships user-facing changes (e.g. `0.1.0` → `0.1.1`). Increment the minor segment after completing a full phase (e.g. `0.1.0` → `0.2.0`). Do not jump to `1.0.0` until the project owner explicitly signs off on a production-ready release.
+
+---
+
+## Git Protocol (Non-Negotiable)
+
+After every major development step, save the work to the repository with an atomic commit and push. Do not accumulate multiple plan's changes into one commit — each plan gets its own commit.
+
+### Commit sequence
+
+```bash
+# 1. Stage all changed files (be explicit — avoid -A when sensitive files may exist)
+git add backend/ frontend/ CLAUDE.md README.md RUNBOOK.md SECURITY.md docker-compose.yml
+
+# 2. Commit with a descriptive message following this format:
+#    <type>(<scope>): <short summary>
+#    where type = feat | fix | docs | refactor | test | chore | security
+git commit -m "feat(phase-N): short description of what was shipped"
+
+# 3. Push to the remote repository immediately
+git push origin main
+```
+
+### Commit types
+
+| Type | When to use |
+|------|-------------|
+| `feat` | New user-facing feature or endpoint |
+| `fix` | Bug fix (root-cause, ≤50 lines) |
+| `docs` | CLAUDE.md, README.md, RUNBOOK.md, or SECURITY.md only |
+| `refactor` | Internal restructuring with no behaviour change |
+| `test` | Adding or fixing tests only |
+| `chore` | Dependencies, CI, build config |
+| `security` | Security hardening, CVE fixes, auth changes |
+
+### When to commit
+
+| Event | Action |
+|-------|--------|
+| Plan execution complete (`/gsd:execute-phase`) | Commit + push immediately after tests pass |
+| Documentation update (CLAUDE.md / README.md) | Commit + push in the same operation as the code it documents |
+| Bug fix during a phase | Commit the fix separately before continuing the plan |
+| Security gate findings resolved | Commit + push before marking the phase complete |
+| Version bump | Part of the plan's commit — not a separate commit |
+
+### Commit message examples
+
+```bash
+git commit -m "feat(07-ai): GenericOpenAIProvider + Anthropic json_schema + Celery retry backoff"
+git commit -m "fix(quota): atomic decrement on document delete — regression test added"
+git commit -m "docs(readme): add cloud storage backend table + alpha status warning"
+git commit -m "security(headers): add X-Correlation-ID + Referrer-Policy to SecurityHeadersMiddleware"
+git commit -m "chore(deps): bump PyMuPDF to 1.26.7 — resolves read-only filesystem issue"
+```
+

+
 ## Testing Protocol (Non-Negotiable)
 
 Every feature, function, and bug fix requires tests. No phase or plan may advance until all tests pass.
