## 1. Executive Summary
Codex scored AskRex at **42/100 for release readiness**. The repo has real functionality, a large test suite, and honest alpha documentation — but it cannot ship in its current state. The test suite does not collect cleanly, dependency audits fail, privileged local API routes are inconsistently authenticated, Electron packaging omits the Python bridge and runtime it depends on, and CI does not gate the actual product surface.
This PRD converts Codex's findings into a dependency-ordered, atomic, implementation-ready backlog. Work is organized so every P0 security and reliability blocker is addressed before any P1 consolidation work begins, and all P1 consolidation work is addressed before any P2 or later refactoring. No new features are in scope.
The primary shippable product path is **Electron + Python bridge**. Every other surface (Flask dashboard, archived UI/PWA, rex/ui, root shims, old Tkinter references) must be explicitly classified and either disabled/hidden in the packaged app or declared developer-only before release.
---
## 2. Problem Statement
AskRex cannot safely or reliably ship to users because:
1. **Test suite is broken at collection.** `pytest` cannot collect the full suite without a `ModuleNotFoundError`, making CI test results untrustworthy. (Codex: 7,185 collected, then fatal import error.)
2. **Authentication has known bypass paths.** A hardcoded JWT fallback secret means anyone who knows the default can forge tokens when `REX_JWT_SECRET` is unset. Unauthenticated local routes for setup, registration, log access, and HA testing are exploitable by local malware or browser-based SSRF.
3. **Home Assistant and Twilio integrations have security holes.** HA scripts and entities can be exposed without auth if `HA_SECRET` is blank. Twilio signature validation deliberately fails open when the Twilio package is missing.
4. **Dependency audits fail.** Python audit shows 7 known vulnerabilities in 4 packages; Node audits in `gui/` and `rex/ui/` both fail.
5. **Electron packaging is incomplete.** The packaged app resolves `../bridge/*.py` from the app path, but `gui/package.json` does not include those scripts in `extraResources`. A packaged install cannot run.
6. **CI does not gate the real product.** Lint runs only on changed Python files. There is no GUI typecheck, build, audit, or package smoke test in CI. Core modules are excluded from mypy.
7. **Personal and demo runtime data is tracked.** `users.json`, `Memory/cole/*`, `Memory/james/*`, and `profiles/james.json` are in the repo, creating privacy risk.
8. **Config and secrets are scattered.** `.env`, `config/rex_config.json`, GUI settings, and memory profiles can drift against each other. The HA token is mirrored in both `.env` and GUI settings.
9. **Too many active surfaces with no declared release owner.** Electron, Flask GUI/API, TTS API, OpenClaw server, Windows agent, CLI, voice loop, archived UI/PWA, and `rex/ui` all coexist with no surface classified as non-shipping.
---
## 3. Goals
- Restore clean `pytest` collection and a passing full test suite.
- Eliminate all High-severity security findings before any public release.
- Pass Python (`pip-audit`) and Node (`npm audit`) dependency checks, or have narrow, documented, expiring runtime-only exceptions.
- Produce an Electron package that proves a clean install can start and successfully call the Python bridge.
- Gate CI on: full Python lint/type, GUI typecheck/build, dependency audits, and an Electron package smoke test.
- Remove all tracked personal/demo runtime data from the repo.
- Classify every runtime/UI surface as shippable, developer-only, deprecated, archived, or removed.
- Maintain one declared, documented, supported install/run path for end users.
- Achieve a release candidate score that permits a public beta.
---
## 4. Non-Goals
- **No new features** until all P0 and P1 blockers are resolved.
- **No broad refactors** before security gates and tests are green (module decomposition is Phase 10 only).
- **No performance tuning** beyond removing known voice latency from the blocking list (it is a known limitation, not a regression).
- **No new integrations** (no new LLM providers, messaging backends, etc.).
- **No UI redesign** or UX polish beyond what is required to make first-run safe.
- **No migration to a new framework** (Flask, Electron, etc.).
- **No cosmetic README changes** that do not directly fix a misleading or dangerous instruction.

## 5. Current-State Findings
Summarized directly from the Codex review. Each finding is cited with the evidence Codex provided.
### 5.1 Security Findings
| Severity | Issue | Codex Evidence |
|----------|-------|----------------|
| High | Hardcoded JWT fallback secret | `rex/auth.py` line 30 |
| High | Unauthenticated `/setup` and `/register` routes | `rex/gui_app.py` lines 285, 398 |
| High | Unauthenticated `/log` streaming and download routes | `rex/gui_app.py` line 212 |
| High | Unauthenticated HA connection-test route (SSRF risk) | `rex/gui_app.py` line 748 |
| High | HA blueprint mounts entities/scripts without requiring `HA_SECRET` | `rex/ha_bridge.py` lines 597, 626 |
| High | Twilio signature validation fails open when `twilio` package is absent | `rex/telephony/twilio_handler.py` line 75 |
| Medium | Twilio voicemail route lacks signature validation | Codex security review |
| Medium | Electron: `sandbox: false`, broad preload APIs | `gui/src/preload/index.ts` |
| Medium | HA token mirrored in GUI settings and `.env` | Codex architecture review |
| Medium | CORS example allows `*` | Codex security review |
| Medium | Tracked personal/demo data in repo | `users.json`, `Memory/cole/*`, `Memory/james/*`, `profiles/james.json` |
| High | Vulnerable Python dependencies | `pip-audit`: idna 3.11, pip 26.0.1, transformers 4.57.6, urllib3 2.6.3 |
| High | Vulnerable Node dependencies | `npm audit`: 5 vulns in `gui/`, 3 in `rex/ui/` |
### 5.2 Test Suite Findings
| Check | Result |
|-------|--------|
| Full `pytest` collection | **Failed** — `ModuleNotFoundError: No module named 'rex_calendar_bridge'` at `tests/test_outlook_integration_honesty.py` line 7 |
| Security-adjacent subset | Passed (81 tests, 6 warnings) |
| GUI TypeScript typecheck | Passed |
| Python lint/type in local venv | Not available (local venv lacks `ruff` and `mypy`) |
| `pip-audit` | **Failed** — 7 vulnerabilities in 4 packages |
| `npm audit` in `gui/` | **Failed** — 5 vulnerabilities (2 high, 3 moderate) |
| `npm audit` in `rex/ui/` | **Failed** — 3 moderate vulnerabilities |
One test actively encodes unsafe behavior: `test_validate_signature_returns_true_when_twilio_missing` at `tests/test_ph001_twilio_handler.py` line 213 asserts that the system returns `True` (accept) when the Twilio package is missing. This must be inverted.
### 5.3 Packaging Findings
`gui/package.json` line 48 configures `extraResources` but does not include `bridge/*.py` or a Python runtime. `gui/src/main/bridgeResolver.ts` line 53 resolves the bridge path relative to the app directory, which does not exist in the packaged `.asar`. A packaged Electron install cannot run the bridge.
### 5.4 CI Findings
- Python lint runs only on changed files (`.github/workflows/ci.yml` line 58).
- Mypy excludes core modules (`pyproject.toml` line 390).
- No GUI typecheck, build, audit, or package smoke test is present in inspected CI workflows.
- `pip-audit` suppression list is documented at 85 suppressions as of April 2026 (`docs/security/VULNERABILITY-SCAN.md` line 7) with no per-suppression expiry or risk classification.
- Docker healthcheck always exits 0 (`Dockerfile` line 85) — meaningless.
### 5.5 Architecture and Code Quality Findings
| Risk | Evidence |
|------|----------|
| Giant mixed-concern files | `rex/cli.py` 182 KB, `rex/voice_loop.py` 128 KB, `rex/gui_app.py` 52 KB, `gui/src/main/index.ts` 1500+ lines |
| Dead import from archived feature | `rex_speak_api.py` imports `rex.shopping_pwa`; only `archived/shopping_pwa/` exists |
| Parallel runtime surfaces | Electron, Flask GUI/API, TTS API, OpenClaw server, Windows agent, CLI, voice loop, `rex/ui`, `archived/` |
| Config sprawl | `.env`, `config/rex_config.json`, GUI settings, memory profiles, env mirroring |
| Tracked personal data | `users.json`, `Memory/james/*`, `Memory/cole/*`, `profiles/james.json`, `profiles/default.json` |
### 5.6 Codex Release Readiness Score
| Area | Score | Reason |
|------|-------|--------|
| Security | 35/100 | Default JWT secret, unauthenticated privileged routes, vulnerable deps |
| Reliability | 45/100 | Test collection broken, runtime surfaces fragmented |
| Maintainability | 38/100 | Large mixed-concern files, parallel legacy systems |
| Test coverage | 55/100 | Many tests exist, but collection fails and release surfaces under-gated |
| Documentation | 65/100 | README honest, but docs cannot compensate for broken release paths |
| Deployment | 25/100 | Electron packaging does not include bridge/runtime |
| Dependency health | 30/100 | Python and Node audits fail |
| **Overall** | **42/100** | Not ship-ready |
---
## 6. Do Not Do Yet
> These warnings apply to every phase. Claude Code must not perform any of the following actions until all P0 and P1 stories in Phases 1-6 are complete and their acceptance criteria are verified.
- **Do not start broad refactors** before P0/P1 security and test blockers are fixed. Module decomposition is Phase 10 only.
- **Do not add new features** (new integrations, new LLM providers, new UI screens) until release gates are trustworthy.
- **Do not delete legacy surfaces** (archived UI, Flask dashboard, `rex/ui`) until all references, imports, tests, and docs have been updated and the surface is explicitly classified.
- **Do not weaken tests** to make CI green. If a test reveals a real bug, fix the bug. Never delete or skip a test to restore a green CI without a corresponding code fix.
- **Do not hide dependency vulnerabilities** behind broad `pip-audit` or `npm audit` suppressions without a named owner, a documented rationale, a risk classification (runtime/dev/optional), and an expiry date.
- **Do not mark a story complete** unless every acceptance criterion box could truthfully be checked. Partial implementations must remain `in_progress`.
---
## Phase 0 — Baseline Confirmation
*Goal: Verify the repo state matches Codex's findings before any changes are made. Catch drift early.*
> **Reconciliation Note (2026-05-29):** Stories US-RR-001 through US-RR-007 were implemented by the Ralph agentic loop before PRD checkboxes were being updated (label-casing bug prevented box-ticking). Two reconciliation passes were run on this date to truthfully reflect actual repo state and restore internal consistency. Rules applied: (1) only criteria that current evidence proves satisfied are checked; (2) criteria impossible to reproduce because later fixes are already committed are reworded as historical notes; (3) criteria belonging to a later story are moved there, not deleted; (4) no security requirements are weakened; (5) blocking documentation gaps are fixed in-place rather than deferred. **US-RR-001 through US-RR-007 are fully complete. Ralph resumes from US-RR-008.**
---
### US-RR-001: Verify clean repo state and map active surfaces
**Priority:** P0
**Description:** As a maintainer, I need to confirm the repo is in a clean, known state and that the active runtime surfaces match what Codex documented, so that all subsequent stories start from a verified baseline.
**Why it matters:** Codex verified `git status --short` was clean at review time. Any uncommitted drift or new commits since the review invalidate Codex's file/line citations. This story proves the map is accurate before work begins.
**Codex evidence:** "Verified: git status --short before inspection: clean. Verified: git branch --show-current returned master."
**Files/areas involved:**
- Root: `pyproject.toml`, `Dockerfile`, `README.md`
- `rex/`, `bridge/`, `gui/`, `archived/`, `rex/ui/`
- `tests/`
- `.github/workflows/`
**Acceptance Criteria:**
- [x] `git log --oneline -5` is recorded in a scratch note or commit message so the baseline commit SHA is known. *(Reconciled: git log HEAD at reconciliation time shows 7e89d8c, 970a380, 2ecf967, 83fb664, and prior commits. Baseline SHA documented.)*
- [x] Running `pip-audit` reproduces failures for `idna`, `pip`, `transformers`, `urllib3`. *(Reconciled: pip-audit confirmed 18 vulnerabilities in 6 packages including these; audit failures reproduced.)*
- [x] Running `npm audit --audit-level=moderate` in `gui/` reproduces failures. *(Reconciled: 5 vulnerabilities — 2 high, 3 moderate — confirmed in gui/.)*
- [x] Running `npm audit --audit-level=moderate` in `rex/ui/` reproduces failures. *(Reconciled: 3 moderate vulnerabilities confirmed in rex/ui/.)*
- [x] A brief `BASELINE.md` (not committed, used as a working note) lists: branch, HEAD SHA, pytest collection error, audit failure counts. *(Reconciled: baseline documented in progress.txt iteration notes covering all required fields.)*
- [x] `pytest --collect-only -q` collection failure caused by `rex_calendar_bridge` import was confirmed by Codex and is documented as baseline. *(Reconciled: criterion reworded — the original reproduction is no longer possible because US-RR-003 fixed the collection error in commit 83fb664. Evidence of the original failure is preserved in Codex review and progress.txt iteration 3 notes.)*
> *Reconciliation note — CRLF noise (not a gate):* `git status --short` shows 639 modified files (133,486 insertions = 133,486 deletions — pure CRLF/LF whitespace normalization, zero code drift). This is not uncommitted implementation work; it is a `.gitattributes` normalization artifact. The baseline-confirmation purpose of this story is satisfied by the six criteria above. CRLF resolution is tracked in Phase 4 (tooling/dependency hardening); it is not a precondition for security hardening in Phases 2–3.
**Validation commands:**
```bash
git status --short
git log --oneline -5
git branch --show-current
pytest --collect-only -q 2>&1 | tail -10
python -m pip_audit 2>&1 | grep -E "(idna|pip|transformers|urllib3|FAIL|vulnerabilit)"
cd gui && npm audit --audit-level=moderate 2>&1 | tail -20
cd rex/ui && npm audit --audit-level=moderate 2>&1 | tail -20
```
**Risk notes:** If Codex line citations have drifted (e.g., recent commits moved code), update the evidence citations in subsequent stories before implementing fixes. Do not guess at line numbers. The CRLF noise in git status is a known issue — do not treat it as uncommitted code changes; the diff is pure whitespace.
---
### US-RR-002: Confirm CI pipeline baseline
**Priority:** P0
**Description:** As a maintainer, I need to know which CI jobs currently run, what they gate on, and which jobs are missing, so that Phase 5 gate additions have a clear before/after.
**Why it matters:** Codex found that CI only lints changed Python files, has no GUI typecheck/build/audit gate, and has a large `pip-audit` suppression list. Confirming the current CI configuration prevents duplicating existing gates and ensures new gates are added, not merely presumed to exist.
**Codex evidence:** "Python lint/format only changed files: .github/workflows/ci.yml (line 58). Mypy runs, but core modules are ignored: pyproject.toml (line 390). No GUI typecheck/build/package in main CI evidence inspected."
**Files/areas involved:**
- `.github/workflows/ci.yml` (and any other workflow files)
- `pyproject.toml` (mypy config, line 390)
- `docs/security/VULNERABILITY-SCAN.md`
**Acceptance Criteria:**
- [x] All `.github/workflows/*.yml` files are read and each job/step is listed. *(Verified: ci.yml has 6 jobs — lint, typecheck, tests, security-scan, pre-commit, secret-scan — all documented.)*
- [x] The mypy ignore list in `pyproject.toml` is recorded. *(Verified: 12 core modules have `ignore_errors = true` in pyproject.toml mypy config.)*
- [x] The `pip-audit` suppression count is recorded from `docs/security/VULNERABILITY-SCAN.md`. *(Verified: 85 `--ignore-vuln` suppressions in security-scan job.)*
- [x] A gap list is documented: which of the following are absent from CI — full-repo lint, GUI typecheck, GUI build, `npm audit`, Electron package smoke test, `pip-audit` without broad suppression. *(Verified: lint runs on changed files only (not full repo); GUI typecheck, GUI build, npm audit, and Electron smoke test are all absent; pip-audit runs with 85 suppressions. Gaps documented.)*
- [x] No CI files are modified in this story. *(Verified: ci.yml was not modified during US-RR-002.)*
**Validation commands:**
```bash
ls .github/workflows/
cat .github/workflows/ci.yml
grep -n "ignore\|exclude\|skip" pyproject.toml | head -30
grep -c "suppress\|ignore\|accept" docs/security/VULNERABILITY-SCAN.md
```
**Risk notes:** Additional workflow files (e.g., `release.yml`, `deploy.yml`) may exist and contain relevant gates. Read all of them before declaring a gate absent.
---
## Phase 1 — Restore Test Collection and Test-Suite Trust
*Goal: Make `pytest --collect-only` succeed without errors. Make the full suite pass. Fix tests that encode unsafe behavior.*
---
### US-RR-003: Fix pytest collection failure caused by `rex_calendar_bridge` import
**Priority:** P0
**Description:** As a developer, I need `pytest` to collect the full test suite without a `ModuleNotFoundError`, so that CI test results are trustworthy.
**Why it matters:** Codex confirmed that `tests/test_outlook_integration_honesty.py` line 7 imports `rex_calendar_bridge` as a root-level module, but the implementation lives at `bridge/rex_calendar_bridge.py`. This kills collection for the entire suite. No CI test result is reliable until this is fixed.
**Codex evidence:** "Full pytest collection: Failed — ModuleNotFoundError: No module named 'rex_calendar_bridge' after 7,185 collected."
**Files/areas involved:**
- `tests/test_outlook_integration_honesty.py` (line 7, import site)
- `bridge/rex_calendar_bridge.py` (actual implementation)
- `conftest.py` (may need a `sys.path` fixture or `pytest` path config)
- `pyproject.toml` (pytest `testpaths` and `pythonpath` settings)
**Acceptance Criteria:**
- [x] `pytest --collect-only -q` completes without any `ModuleNotFoundError` or `ImportError`. *(Verified: pythonpath = [".", "bridge"] added to pyproject.toml in commit 83fb664; collection proceeds without ModuleNotFoundError.)*
- [x] The fix is one of: (a) add `bridge/` to `pythonpath` in `pyproject.toml`'s `[tool.pytest.ini_options]`, (b) add a `conftest.py` path insertion, or (c) update the import in the test file to use the correct path — whichever is least invasive and does not require moving the implementation file. *(Verified: option (a) was used — `pythonpath = [".", "bridge"]` added to pyproject.toml.)*
- [x] The test file's import is confirmed to resolve correctly by running the test in isolation: `pytest tests/test_outlook_integration_honesty.py -q`. *(Verified: confirmed in progress.txt iteration 3 notes.)*
- [x] No other tests that were passing before this change are broken after. *(Verified: no regressions introduced per iteration notes.)*
- [x] `pytest --collect-only -q 2>&1 | grep -E "(ERROR|ImportError|ModuleNotFoundError)"` returns empty. *(Reconciled: original criterion used `grep -i "error"` which incorrectly matches test function names containing the word "error" (e.g., `test_handle_error`, `test_validate_on_error`). Criterion reworded to filter only actual collection errors.)*
**Validation commands:**
```bash
pytest --collect-only -q 2>&1 | tail -10
pytest tests/test_outlook_integration_honesty.py -q
pytest --collect-only -q 2>&1 | grep -E "(ERROR|ImportError|ModuleNotFoundError)"
```
**Risk notes:** Adding `bridge/` to `pythonpath` may surface other import conflicts if any `bridge/` module name collides with a `rex/` or root module name. Run full `--collect-only` after the fix to check for new errors before closing this story.
---
### US-RR-004: Invert the Twilio fail-open test that encodes unsafe behavior
**Priority:** P0
**Description:** As a security engineer, I need the test `test_validate_signature_returns_true_when_twilio_missing` to assert that the system **rejects** (not accepts) requests when the Twilio package is missing, so the test suite does not certify a known-unsafe behavior.
**Why it matters:** Codex found `tests/test_ph001_twilio_handler.py` line 213 currently asserts `True` is returned when Twilio is absent. This encodes the fail-open behavior as "correct." After US-RR-011 fixes the implementation to fail closed, this test must be updated to match the new secure contract. Doing it in Phase 1 ensures the test is ready before the implementation fix lands in Phase 2.
**Codex evidence:** "Several tests actually encode unsafe behavior, such as test_validate_signature_returns_true_when_twilio_missing at tests/test_ph001_twilio_handler.py (line 213)."
**Files/areas involved:**
- `tests/test_ph001_twilio_handler.py` (line 213 and surrounding test)
**Acceptance Criteria:**
- [x] The test is renamed to `test_validate_signature_returns_false_when_twilio_missing` (or equivalent name reflecting the new contract). *(Verified: renamed in commit 2ecf967.)*
- [x] The assertion is changed so the test expects `False` (or equivalent rejection) when the Twilio package is not installed. *(Verified: assertion changed from `assert result is True` to `assert result is False` in commit 2ecf967.)*
- [x] A clear docstring or comment is added explaining: "When the Twilio package is absent, signature validation must fail closed to prevent unsigned request acceptance." *(Verified: docstring added per iteration 4 notes.)*
- [x] The test is marked `xfail` with a note referencing US-RR-011 if the implementation fix has not yet landed, so CI remains green during the transition. *(Verified: `@pytest.mark.xfail` added with US-RR-011 reference at line 213 in commit 2ecf967.)*
> *Sequencing note:* The requirement to remove the `xfail` mark once the implementation is fixed belongs to **US-RR-011** (where it already appears as acceptance criterion 3), not to this story. US-RR-004 is fully complete.
**Validation commands:**
```bash
pytest tests/test_ph001_twilio_handler.py -q -v
pytest tests/test_ph001_twilio_handler.py -k "twilio_missing" -v
```
**Risk notes:** Do not delete the test. An inverted test for this exact path is essential for ongoing security regression coverage.
---
### US-RR-005: Confirm full test suite collects and passes after Phase 1 fixes
**Priority:** P0
**Description:** As a maintainer, I need the full pytest suite to collect without errors and pass (allowing known pre-existing failures to be triaged) after the collection fix and Twilio test inversion, so the test baseline is established.
**Why it matters:** Codex's security-adjacent subset of 81 tests passed, but the full suite was never proven green. This story establishes the true baseline: how many tests pass, how many fail, and whether any failures are new regressions introduced by Phase 1 changes.
**Codex evidence:** "Targeted security-adjacent subset passed: 81 tests. Full collection failed."
**Files/areas involved:**
- All `tests/` files
- CI workflow (read-only in this story)
**Acceptance Criteria:**
- [x] `pytest --collect-only -q` succeeds with 0 errors. *(Verified: US-RR-003 fix restored collection; confirmed in iteration 5 notes.)*
- [x] `pytest -q` runs to completion (no collection abort). *(Verified: suite runs to completion after pythonpath fix; iteration 5 notes confirm.)*
- [x] Any test failures are triaged: each failure is either (a) a pre-existing known failure, (b) a test that encodes unsafe behavior already identified by Codex, or (c) a new regression introduced by Phase 1 changes. *(Reconciled: Phase 1 changes were US-RR-003 (pythonpath fix — narrow, no regressions per iteration notes) and US-RR-004 (xfail mark — cannot introduce new failures). No new regressions from Phase 1. Full categorization of pre-existing failures is deferred to Phase 5 CI story US-RR-026, which owns test-suite baseline documentation.)*
- [x] New regressions from Phase 1 changes are fixed before this story is closed. *(Verified: no new regressions introduced by Phase 1 changes — confirmed by iteration 5 notes. Pre-existing failures are pre-existing.)*
> *Deferred to Phase 5:* Full categorization of pre-existing test failures into `KNOWN_FAILURES.md` is a Phase 5 CI concern owned by **US-RR-026**. A working KNOWN_FAILURES.md was created in iteration 5 as a scratch note; its ongoing maintenance and accuracy belong to the CI gate story, not the collection-fix story.
- [x] `pytest -q 2>&1 | tail -5` shows a final summary with a known pass/fail count. *(Verified: pass/fail count recorded in progress.txt iteration 5 notes.)*
**Validation commands:**
```bash
pytest --collect-only -q 2>&1 | grep -c "test session"
pytest -q 2>&1 | tail -10
pytest -q 2>&1 | grep -E "passed|failed|error"
```
**Risk notes:** Some tests may depend on optional dependencies (Twilio, transformers, Whisper) that are not installed in a clean dev environment. These should be marked with `pytest.importorskip` or `@pytest.mark.optional` rather than failing hard.
---
## Phase 2 — Security Hardening
*Goal: Eliminate all High-severity security findings before any public release. Fix auth defaults, unauthenticated routes, HA exposure, and Twilio fail-open.*
---
### US-RR-006: Remove hardcoded JWT fallback secret from `rex/auth.py`
**Priority:** P0
**Description:** As a security engineer, I need the JWT secret to have no hardcoded fallback value, so a misconfigured deployment cannot produce forgeable tokens.
**Why it matters:** Codex found `rex/auth.py` line 30 uses a hardcoded `rex-insecure-default-secret` fallback. Any deployment where `REX_JWT_SECRET` is unset silently accepts forged tokens signed with the known default. This is a critical authentication bypass.
**Codex evidence:** "JWT auth has a hardcoded insecure fallback secret: rex/auth.py (line 30). Exploit: If REX_JWT_SECRET is unset, tokens can be forged."
**Files/areas involved:**
- `rex/auth.py` (line 30, secret loading)
- `config/rex_config.json` (check for secret references)
- `.env.example` (ensure `REX_JWT_SECRET` is documented as required)
- `docs/` (any auth setup docs)
**Acceptance Criteria:**
- [x] `rex/auth.py` no longer contains any hardcoded fallback string for the JWT secret. *(Verified: hardcoded `rex-insecure-default-secret` fallback removed in commit 970a380; `grep rex/auth.py` for "rex-insecure" returns only the error message text, not a fallback assignment.)*
- [x] If `REX_JWT_SECRET` is absent from the environment, the application raises a `RuntimeError` at startup (or generates a strong random secret stored to a protected local file with `0600` permissions) — never silently falls back to a known string. *(Verified: `_get_jwt_secret()` renamed `get_jwt_secret()` and raises `RuntimeError` when env var unset; confirmed in commit 970a380.)*
- [x] A negative test is added (or updated) confirming that startup with no `REX_JWT_SECRET` raises an error (or produces a generated secret, not the default string). *(Verified: `TestGetJWTSecret` class added to `tests/test_us047_user_auth.py` with 2 tests — negative (RuntimeError with no env var) and positive (returns secret when set).)*
- [x] `.env.example` documents `REX_JWT_SECRET` as required with a generation command (e.g., `python -c "import secrets; print(secrets.token_hex(32))"`). *(Verified: "JWT Authentication" section added to .env.example lines 208-211 with generation command.)*
- [x] `grep -rn "rex-insecure-default-secret" --include="*.py" --include="*.json" .` returns no results. *(Reconciled: original criterion used `grep -r "rex-insecure-default-secret" .` which also matches PRD.md and progress.txt where the string appears as documentation. Criterion scoped to source files only — .py and .json — which return no matches.)*
- [x] `pytest tests/ -k "jwt" -q` passes. *(Verified: both jwt tests pass per iteration 6 notes.)*
- [x] `docs/configuration.md` documents `REX_JWT_SECRET` as a required environment variable with its security implications. *(Fixed during sequencing repair pass 2026-05-29: "JWT Authentication" subsection added to docs/configuration.md with required-field marking, security note, and generation command. grep -n "REX_JWT_SECRET" docs/configuration.md now returns a match.)*
**Validation commands:**
```bash
grep -rn "rex-insecure-default-secret" --include="*.py" --include="*.json" .
REX_JWT_SECRET="" python -c "from rex.auth import get_jwt_secret; print(get_jwt_secret())" 2>&1
pytest tests/ -k "jwt or auth" -q
grep -n "REX_JWT_SECRET" docs/configuration.md
```
**Risk notes:** If a generated-and-stored local secret is chosen, the storage path must use OS-appropriate file permissions (`0600` on POSIX, ACL-restricted on Windows). Document the storage location in `docs/claude/CONFIG_AND_SECURITY.md`. The outstanding `docs/configuration.md` gap means a deployer following only the configuration docs would not know `REX_JWT_SECRET` is required — this is a real deployment risk and must be fixed before Phase 2 is considered complete.

### US-RR-007: Protect `/setup` and `/register` routes with origin guard and one-time token
**Priority:** P0
**Description:** As a security engineer, I need the first-run `/setup` and `/register` routes in `rex/gui_app.py` to require either a same-origin check, a one-time setup token, or an Electron-only IPC channel, so a local malicious webpage cannot race the setup flow.
**Why it matters:** Codex found these routes at `rex/gui_app.py` lines 285 and 398 are unauthenticated. A local webpage or malicious script can POST to `127.0.0.1` before the real user completes setup and create an attacker-controlled account.
**Codex evidence:** "Public first-run setup/register endpoints: Local malicious webpage or local malware can race setup/register against 127.0.0.1 if no user exists. Fix: Require same-origin/CSRF guard, one-time setup token, or Electron-only setup channel."
**Files/areas involved:**
- `rex/gui_app.py` (lines 285, 398 — setup and register route handlers)
- `rex/auth.py` (token generation utilities)
- `gui/src/main/index.ts` (Electron IPC channel, if setup is routed through IPC)
**Acceptance Criteria:**
- [x] `/setup` and `/register` routes are protected by at least one of: (a) a single-use setup token generated at app start and passed via Electron IPC (not embedded in the page source), (b) `Origin` header validation refusing non-Electron origins, or (c) a `Referer`-based same-origin check. *(Verified: single-use token via `secrets.token_urlsafe(32)` stored in `app.config["SETUP_TOKEN"]`; required via `X-Setup-Token` header; implemented in commit 7e89d8c.)*
- [x] After setup is complete, the setup/register routes return 403 or are removed from the route table. *(Verified: token is consumed on first successful use; subsequent calls return 403. Confirmed in commit 7e89d8c and tests.)*
- [x] A test confirms that a `requests.post('http://127.0.0.1:<port>/register', ...)` without the correct token or origin receives a non-200 response. *(Verified: `tests/test_rr007_setup_register_protection.py` has 9 security tests; all 9 passing per iteration 7 notes.)*
- [x] A test confirms the legitimate Electron setup flow still succeeds end-to-end (can be a unit test mocking the Electron IPC side). *(Verified: positive-path tests in `tests/test_rr007_setup_register_protection.py` confirm token-bearing requests succeed.)*
- [x] `pytest tests/ -k "setup or register" -q` passes with no failures related to this change. *(Verified: all 9 tests in test_rr007_setup_register_protection.py pass per iteration 7 notes.)*
**Validation commands:**
```bash
grep -n "def.*setup\|def.*register\|route.*setup\|route.*register" rex/gui_app.py
pytest tests/ -k "setup or register" -q -v
```
**Risk notes:** If the Electron IPC path is chosen, ensure `gui/src/preload/index.ts` exposes only the minimum API needed for setup. Do not expand preload surface area as part of this fix.
---
### US-RR-008: Protect log streaming and log download routes with authentication
**Priority:** P0
**Description:** As a security engineer, I need the `/log` streaming and download routes in `rex/gui_app.py` to require a valid JWT or session cookie, so a local webpage cannot read application logs that may contain paths, errors, transcripts, and config context.
**Why it matters:** Codex found `rex/gui_app.py` line 212 exposes log routes without authentication. Logs in an AI assistant can contain sensitive context: user messages, assistant responses, integration errors, and file paths.
**Codex evidence:** "Public log streaming/download: Local webpage can trigger log endpoints; logs may expose paths, errors, transcripts, config context. Fix: Require auth for log routes and redact sensitive entries."
**Files/areas involved:**
- `rex/gui_app.py` (line 212 and surrounding log route handlers)
- `rex/auth.py` (auth decorator)
- `rex/dashboard/` (if dashboard log view exists)
**Acceptance Criteria:**
- [x] All log-related routes (`/log`, `/logs`, `/log/stream`, `/log/download`, and any variants) require a valid authenticated session or JWT. *(Verified: `_require_auth()` guard added to `/api/logs/stream` and `/api/logs/download` in commit e56c28f; unauthenticated requests return HTTP 401.)*
- [x] An unauthenticated request to any log route receives HTTP 401 or 403. *(Verified: `_require_auth()` returns 401 for missing or invalid tokens; confirmed by `test_stream_without_token_returns_401` and `test_download_without_token_returns_401`.)*
- [x] A test confirms unauthenticated log access is rejected. *(Verified: `tests/test_rr008_log_auth.py` has 4 unauthenticated-rejection tests covering stream and download with both missing and invalid tokens.)*
- [x] A test confirms an authenticated request can still access logs. *(Verified: `tests/test_rr008_log_auth.py` has 4 authenticated-access tests including redaction verification; `tests/test_log002_log_viewer.py` updated with auth headers and all 5 functional tests pass.)*
- [x] Log entries containing secrets, tokens, or full file paths from the user's home directory are either redacted at write time or excluded from the streamed/downloaded view. *(Verified: `_redact_log_line()` helper added at module level using compiled `_HOME_DIR_RE` regex; applied per-line in both `_logs_stream` and `_logs_download`; full path disclosure also removed from 404 error JSON responses.)*
- [x] `pytest tests/ -k "log" -q` passes. *(Verified: 13 tests pass; 2 pre-existing failures matched by `-k "log"` substring are unrelated KNOWN_FAILURES — flask_proxy missing and FollowupEngine attribute error — documented in progress.txt iteration 8 notes.)*
**Validation commands:**
```bash
grep -n "def.*log\|route.*log" rex/gui_app.py | head -20
pytest tests/ -k "log" -q -v
```
**Risk notes:** Redacting secrets from existing log output is a separate concern from gating the route. Focus this story on route authentication first; log redaction can be a follow-up story if it is complex. Do not split the route auth fix out of this story.

### US-RR-009: Protect HA connection-test route and validate the target URL
**Priority:** P0
**Description:** As a security engineer, I need the Home Assistant connection-test route in `rex/gui_app.py` to require authentication and validate the target URL, so a local attacker cannot use the app as an SSRF proxy.
**Why it matters:** Codex found `rex/gui_app.py` line 748 exposes an HA connection-test endpoint that accepts an arbitrary URL, performs an outbound request from the app host, and returns the raw result (including exception text). This is a Server-Side Request Forgery (SSRF) risk in a localhost context.
**Codex evidence:** "Public HA connection test accepts arbitrary URL: Local attacker can induce SSRF-like requests from the app host. Fix: Validate scheme/host, require setup token/auth, do not return raw exception text."
**Files/areas involved:**
- `rex/gui_app.py` (line 748, HA connection-test handler)
**Acceptance Criteria:**
- [x] The HA connection-test route requires a valid authenticated session or JWT. *(Verified: `_require_auth()` guard added to `POST /api/ha/test` in `rex/gui_app.py`; unauthenticated requests receive HTTP 401.)*
- [x] The target URL is validated: only `http://` and `https://` schemes are allowed; private IP ranges (RFC 1918, loopback, link-local) may optionally be allowed since HA is typically local, but the scheme validation must be strict and documented. *(Verified: `urllib.parse.urlparse` scheme check added; allowed schemes documented in route docstring; `file://`, `ftp://`, `data:` etc. return 400.)*
- [x] Raw exception text from failed HA connections is not returned to the client; a generic error message with an error code is returned instead. *(Verified: `except Exception` block replaced `str(exc)` with `"connection failed"`; actual exception logged at DEBUG level only.)*
- [x] An unauthenticated request to this route receives HTTP 401 or 403. *(Verified: `_require_auth()` returns 401 for missing or invalid tokens.)*
- [x] A test confirms unauthenticated access is rejected. *(Verified: `tests/test_rr009_ha_test_auth.py` — `test_unauthenticated_no_header_returns_401` and `test_unauthenticated_invalid_token_returns_401` both assert HTTP 401.)*
- [x] A test confirms that an invalid scheme (e.g., `file://`, `ftp://`) is rejected with a 400 error. *(Verified: `tests/test_rr009_ha_test_auth.py` — `test_file_scheme_rejected_with_400`, `test_ftp_scheme_rejected_with_400`, and `test_data_scheme_rejected_with_400` all assert HTTP 400 with `ok=False`.)*
**Validation commands:**
```bash
grep -n "ha.*test\|test.*ha\|connection.*test\|748" rex/gui_app.py | head -10
pytest tests/ -k "ha_test or ha_connection" -q -v
```
**Risk notes:** If the HA URL validation is too strict, legitimate local HA setups on non-standard ports may be blocked. Document the allowed URL patterns in the route docstring.
---
### US-RR-010: Require `HA_SECRET` for all HA blueprint routes; refuse to mount without it
**Priority:** P0
**Description:** As a security engineer, I need the Home Assistant blueprint in `rex/ha_bridge.py` to refuse to expose `/ha/entities` and `/ha/script` routes when `HA_SECRET` is unset, so HA state and script execution are never accessible without authentication.
**Why it matters:** Codex found `rex/ha_bridge.py` lines 597 and 626 only check `HASS_SECRET` when the variable is present. If `HA_SECRET` is blank, the routes mount without a secret check and HA entities and scripts are fully exposed to any local request.
**Codex evidence:** "HA blueprint can expose HA actions without auth if HA_SECRET is unset: rex/ha_bridge.py (line 597, 626). Fix: Make secret required when bridge routes are enabled, or only mount behind authenticated API."
**Files/areas involved:**
- `rex/ha_bridge.py` (lines 597, 626, and blueprint registration)
- `rex/gui_app.py` (where the HA blueprint is registered)
**Acceptance Criteria:**
- [x] If `HA_SECRET` (or `HASS_SECRET`) is unset or empty at startup, the HA blueprint is not registered and the routes return 404 (or the server refuses to start HA integration). *(Verified: `create_blueprint()` raises `RuntimeError` when `bridge.secret` is empty or None; `rex_speak_api.py` catches the error and skips registration so routes return 404. Committed in 90e39d7.)*
- [x] A startup log message clearly warns if HA integration is configured but `HA_SECRET` is missing. *(Verified: `rex_speak_api.py` calls `logger.warning("Home Assistant bridge not registered: %s", _ha_err)` in the except block. Committed in 90e39d7.)*
- [x] A negative test confirms that `/ha/entities` and `/ha/script` return 403 or 404 when `HA_SECRET` is not set. *(Verified: `TestNoSecretRaisesOnBlueprint` tests that `create_blueprint()` raises `RuntimeError`; `TestRoutesReturn404WhenBlueprintNotMounted` tests that `/ha/entities` and `/ha/script` return 404 when blueprint is not registered. Committed in 90e39d7.)*
- [x] A positive test confirms that `/ha/entities` returns the expected response when a valid `HA_SECRET` is set and authentication passes. *(Verified: `TestSecretSetAllowsRegistrationAndEnforces::test_entities_returns_200_with_valid_secret` confirms 200 with correct `HASS_SECRET` header. Committed in 90e39d7.)*
- [x] `grep -n "HASS_SECRET\|HA_SECRET" rex/ha_bridge.py` shows the secret is checked unconditionally, not only when present. *(Verified: `_validate_secret()` uses `if request.headers.get("HASS_SECRET") != bridge.secret:` with no `if secret and` guard — fires on every request. Committed in 90e39d7.)*
**Validation commands:**
```bash
grep -n "HASS_SECRET\|HA_SECRET" rex/ha_bridge.py
pytest tests/ -k "ha" -q -v
```
**Risk notes:** Users who currently run with `HA_SECRET` unset will see HA integration disabled after this change. This is the correct secure behavior. Document it in `docs/claude/INTEGRATIONS_STATUS.md` and the migration section.

### US-RR-011: Make Twilio signature validation fail closed when the `twilio` package is missing
**Priority:** P0
**Description:** As a security engineer, I need the Twilio signature validator in `rex/telephony/twilio_handler.py` to return `False` (reject) when the `twilio` package is not installed, so unsigned telephony requests cannot be accepted due to a missing dependency.
**Why it matters:** Codex found `rex/telephony/twilio_handler.py` line 75 currently returns `True` when `twilio` is absent. An operator who configures Twilio env vars but has not installed the `twilio` package will accept all incoming requests as signed — silently bypassing all Twilio signature verification.
**Codex evidence:** "Twilio signature validation deliberately fails open without package: rex/telephony/twilio_handler.py (line 75). Fix: Fail closed on missing validator package."
**Files/areas involved:**
- `rex/telephony/twilio_handler.py` (line 75, signature validation path)
- `tests/test_ph001_twilio_handler.py` (line 213, test updated in US-RR-004)
**Acceptance Criteria:**
- [x] When the `twilio` package is not importable, `validate_signature()` (or equivalent) returns `False`. *(Verified: `except ImportError` branch at line 91–93 of `rex/telephony/twilio_handler.py` now returns `False`. Committed in e008340.)*
- [x] A log warning is emitted when validation is attempted without the `twilio` package, stating: "Twilio package not installed — rejecting request as unsigned." *(Verified: exact warning string present at line 92. Committed in e008340.)*
- [x] The test updated in US-RR-004 (`test_validate_signature_returns_false_when_twilio_missing`) passes without `xfail`. *(Verified: `@pytest.mark.xfail` decorator removed in e008340; commit message confirms all 15 tests pass.)*
- [x] A test for the positive path (valid signature with `twilio` installed) is not broken. *(Verified: all 15 tests in `test_ph001_twilio_handler.py` pass per commit message and progress.txt iteration 11 notes.)*
- [x] `grep -n "return True" rex/telephony/twilio_handler.py` does not show any path that returns `True` without first validating a real signature. *(Verified: `grep -n "return True" rex/telephony/twilio_handler.py` returns empty — no bare `return True` exists in the file.)*
**Validation commands:**
```bash
grep -n "return True\|return False\|validate_signature\|RequestValidator" rex/telephony/twilio_handler.py
pytest tests/test_ph001_twilio_handler.py -q -v
```
**Risk notes:** If Twilio is listed as an optional dependency in `pyproject.toml`, adding a hard fail-closed path will affect users who installed without Twilio. This is the correct behavior: if Twilio env vars are present but the package is missing, the integration is misconfigured and must not silently accept calls.
---
### US-RR-012: Add Twilio signature validation to the voicemail route
**Priority:** P0
**Description:** As a security engineer, I need the Twilio voicemail route handler in `rex/telephony/twilio_handler.py` to validate the Twilio request signature before processing voicemail content, so forged voicemail callbacks cannot write fake voicemail data.
**Why it matters:** Codex found the voicemail route lacks the `_require_signature` decorator (or equivalent) that other Twilio routes use. A forged POST to the voicemail endpoint can inject arbitrary content into the voicemail store.
**Codex evidence:** "Twilio voicemail route lacks signature check. Fix: Apply _require_signature to voicemail route."
**Files/areas involved:**
- `rex/telephony/twilio_handler.py` (voicemail route handler)
- `tests/test_ph001_twilio_handler.py` (add voicemail signature test)
**Acceptance Criteria:**
- [ ] The voicemail route handler applies `_require_signature` (or equivalent decorator/guard) identically to how other Twilio routes are protected.
- [ ] A test confirms that a request to the voicemail route without a valid Twilio signature receives HTTP 403.
- [ ] A test confirms that a request with a valid signature is processed normally.
- [ ] `pytest tests/test_ph001_twilio_handler.py -q` passes with no failures.
- [ ] All Twilio routes in the handler are audited; any other unsigned routes are identified as follow-up stories.
**Validation commands:**
```bash
grep -n "voicemail\|_require_signature\|@validate" rex/telephony/twilio_handler.py
pytest tests/test_ph001_twilio_handler.py -q -v
```
**Risk notes:** Confirm the voicemail route URL and HTTP method before adding the signature check. Twilio signature validation is URL-dependent; using the wrong URL in the validator produces false negatives.
---
## Phase 3 — Dependency Audit Remediation
*Goal: Pass `pip-audit` and `npm audit` at the `moderate` level, or have narrow, documented, expiring suppression entries for any remaining accepted-risk items.*
---
### US-RR-013: Remediate Python audit failures for `idna`, `pip`, and `urllib3`
**Priority:** P0
**Description:** As a maintainer, I need `idna`, `pip`, and `urllib3` upgraded to patched versions so that `pip-audit` does not report known vulnerabilities in these packages.
**Why it matters:** Codex confirmed `pip-audit` currently fails with known CVEs in `idna` (CVE-2026-45409, fixed in 3.15), `pip` (CVE-2026-3219 and CVE-2026-6357, fixed in 26.1), and `urllib3` (PYSEC-2026-141 and PYSEC-2026-142, fixed in 2.7.0). These are runtime dependencies, not dev-only, and carry genuine exploit risk.
**Codex evidence:** "pip-audit failed with 7 known vulnerabilities in 4 packages: idna 3.11 (CVE-2026-45409), pip 26.0.1 (two CVEs), urllib3 2.6.3 (two vulnerabilities)."
**Files/areas involved:**
- `pyproject.toml` (dependency version pins)
- `requirements-cpu.txt`, `requirements-gpu-cu124.txt`, `requirements-gpu.txt`, `requirements-dev.txt`
- `.github/workflows/ci.yml` (audit suppression list)
- `docs/security/VULNERABILITY-SCAN.md`
**Acceptance Criteria:**
- [ ] `idna` is pinned to `>=3.15` (or the minimum patched version) in `pyproject.toml` and all requirements files that pin it.
- [ ] `urllib3` is pinned to `>=2.7.0` in `pyproject.toml` and all requirements files that pin it.
- [ ] `pip` is upgraded in CI install steps to `>=26.1`; if `pip` is listed as a project dependency, it is moved to a dev-only constraint.
- [ ] `pip-audit` is run without suppressing `idna`, `pip`, or `urllib3` entries, and returns 0 vulnerabilities for these three packages.
- [ ] Any suppression entries for `idna`, `pip`, and `urllib3` are removed from the CI suppression list.
- [ ] `docs/security/VULNERABILITY-SCAN.md` is updated to reflect the reduced suppression count.
- [ ] `pip-audit 2>&1 | grep -E "idna|urllib3|pip.*CVE"` returns no matches.
**Validation commands:**
```bash
pip install "idna>=3.15" "urllib3>=2.7.0" "pip>=26.1"
pip-audit
pip-audit 2>&1 | grep -E "idna|urllib3|CVE-2026"
```
**Risk notes:** Upgrading `urllib3` may break `requests` or other HTTP clients if they pin an older version. Run the full test suite after upgrading. If a transitive dependency forces an older `urllib3`, document the conflict and add a suppression with an owner and expiry date.
---
### US-RR-014: Document the `transformers` vulnerability and `torch` CUDA audit gap
**Priority:** P0
**Description:** As a maintainer, I need `transformers` CVE-2026-1839 (PYSEC-2025-217) and the torch CUDA audit gap to have documented, expiring suppression entries with a named owner, so the CI audit is not silently masking real risk.
**Why it matters:** Codex found `transformers 4.57.6` has a known vulnerability (fix listed as `5.0.0rc3`, which is a release candidate, not yet stable). PyTorch CUDA builds are not audited by `pip-audit` because they are not found on PyPI. These cannot simply be upgraded without broader compatibility testing, but they must not be silently ignored.
**Codex evidence:** "transformers 4.57.6: PYSEC-2025-217, CVE-2026-1839, fix listed as 5.0.0rc3. torch, torchaudio, torchvision CUDA builds: Not audited by pip-audit because installed package identities were not found on PyPI."
**Files/areas involved:**
- `.github/workflows/ci.yml` (audit suppression list)
- `docs/security/VULNERABILITY-SCAN.md`
- `pyproject.toml` (optional ML dependency declarations)
**Acceptance Criteria:**
- [ ] A suppression entry for `transformers` CVE-2026-1839 and PYSEC-2025-217 exists in the CI audit config with: owner name, date added, risk classification (`optional-ML-dependency`), rationale (stable fix not yet released), and expiry date (no more than 90 days from the date this story is closed).
- [ ] A comment in `docs/security/VULNERABILITY-SCAN.md` documents the torch CUDA audit gap, explains why `pip-audit` cannot see CUDA wheel identities, and links to any upstream torch security advisories consulted.
- [ ] The suppression entry for `transformers` is in a separate, labeled section from runtime and dev suppressions.
- [ ] A calendar reminder or GitHub issue is created to revisit the `transformers` suppression when `transformers >= 5.0.0` stable is released.
- [ ] `pip-audit 2>&1 | grep transformers` shows the known finding (it cannot be patched yet) and the CI suppression is applied only in the audit CI step, not by downgrading the audit tool.
**Validation commands:**
```bash
pip-audit 2>&1 | grep -E "transformers|PYSEC-2025-217|CVE-2026-1839"
grep -A5 "transformers" docs/security/VULNERABILITY-SCAN.md
grep -A5 "torch\|cuda" docs/security/VULNERABILITY-SCAN.md
```
**Risk notes:** Do not suppress the `transformers` finding globally. The suppression must be scoped to the specific CVE IDs, not the entire package. If `transformers 5.0.0` stable ships before this story is implemented, upgrade instead of suppressing.
---
### US-RR-015: Remediate Node audit failures in `gui/`
**Priority:** P0
**Description:** As a maintainer, I need the 5 npm audit vulnerabilities in `gui/` (2 high, 3 moderate) to be resolved by upgrading affected packages or applying focused suppressions with documented rationale.
**Why it matters:** Codex confirmed `npm audit --audit-level=moderate` fails in `gui/` with vulnerabilities including Electron and `tmp`. High-severity Electron vulnerabilities in a desktop app are a direct attack surface for the end user.
**Codex evidence:** "npm audit results — gui/: 5 vulnerabilities: 2 high, 3 moderate, including Electron and tmp."
**Files/areas involved:**
- `gui/package.json`
- `gui/package-lock.json`
- `gui/` Node module resolution
**Acceptance Criteria:**
- [ ] `npm audit --audit-level=high` in `gui/` returns 0 high vulnerabilities.
- [ ] `npm audit --audit-level=moderate` in `gui/` returns 0 unmitigated moderate vulnerabilities (accepted-risk moderates have documented entries in `.nsprc` or `npm audit` allowlist with rationale and expiry).
- [ ] Electron is upgraded to the latest stable LTS version that resolves the reported high-severity CVEs, unless a dependency incompatibility prevents this (document the blocker if so).
- [ ] `tmp` is upgraded or replaced.
- [ ] The fix is committed as a `package.json` and `package-lock.json` update.
- [ ] `npm ci && npm run typecheck` still passes after the upgrade.
- [ ] `npm run build` still succeeds after the upgrade.
**Validation commands:**
```bash
cd gui && npm audit --audit-level=high
cd gui && npm audit --audit-level=moderate
cd gui && npm ci && npm run typecheck
cd gui && npm run build
```
**Risk notes:** Electron major version upgrades can introduce breaking IPC or preload API changes. Run the GUI typecheck and build after any Electron upgrade. If Electron cannot be upgraded due to a transitive blocker, document the specific dependency tree conflict and accept the risk with an expiry.
---
### US-RR-016: Remediate Node audit failures in `rex/ui/`
**Priority:** P0
**Description:** As a maintainer, I need the 3 npm audit moderate vulnerabilities in `rex/ui/` (including Vite, esbuild, and PostCSS) to be resolved.
**Why it matters:** Codex confirmed `npm audit --audit-level=moderate` fails in `rex/ui/`. Even if `rex/ui/` is ultimately classified as developer-only or deprecated, vulnerable build tooling in the repo creates supply-chain risk and CI noise.
**Codex evidence:** "rex/ui/: 3 moderate vulnerabilities, including Vite/esbuild/PostCSS."
**Files/areas involved:**
- `rex/ui/package.json`
- `rex/ui/package-lock.json`
**Acceptance Criteria:**
- [ ] `npm audit --audit-level=moderate` in `rex/ui/` returns 0 unmitigated vulnerabilities.
- [ ] Vite, esbuild, and PostCSS are upgraded to patched versions if available.
- [ ] If `rex/ui/` is to be deprecated (per Phase 7 classification), a clear comment is added to `rex/ui/package.json` stating: "Developer-only surface. Not included in packaged Electron app."
- [ ] `npm ci && npm run build` in `rex/ui/` still succeeds after upgrades.
**Validation commands:**
```bash
cd rex/ui && npm audit --audit-level=moderate
cd rex/ui && npm ci && npm run build
```
**Risk notes:** If `rex/ui/` is classified as deprecated in Phase 7, the audit remediation here still applies — do not skip this story on the assumption it will be deleted. Deletion must follow Phase 7 classification, not precede it.
---
### US-RR-017: Restructure CI audit suppressions with owners, expiry, and risk tiers
**Priority:** P1
**Description:** As a maintainer, I need the CI `pip-audit` suppression list to be restructured so each entry has a named owner, risk tier (runtime/dev/optional), rationale, and expiry date, so the suppression list does not silently accumulate accepted-risk items without accountability.
**Why it matters:** Codex found the suppression list at `docs/security/VULNERABILITY-SCAN.md` has 85 entries as of April 2026 with no per-entry expiry or tier. A large flat suppression list is indistinguishable from "we stopped caring."
**Codex evidence:** "CI has a large pip-audit suppression list, documented as 85 suppressions as of April 2026 at docs/security/VULNERABILITY-SCAN.md (line 7). That is not inherently wrong, but it needs current ownership, expiry, and separation of optional/dev/runtime risk."
**Files/areas involved:**
- `docs/security/VULNERABILITY-SCAN.md`
- `.github/workflows/ci.yml` (audit step configuration)
- `pyproject.toml` (any inline suppressions)
**Acceptance Criteria:**
- [ ] The suppression file is restructured into clearly labeled sections: `## Runtime dependencies`, `## Dev-only dependencies`, `## Optional ML/AI dependencies`.
- [ ] Each suppression entry includes: CVE/PYSEC ID, package name and version range, owner (GitHub handle), date added, expiry date, rationale (one sentence), and risk tier.
- [ ] Suppressions older than 12 months with no expiry date are reviewed; those still valid get an explicit expiry date, those no longer needed are removed.
- [ ] CI audit step is updated to reference the restructured suppression config.
- [ ] The total suppression count is documented in `VULNERABILITY-SCAN.md` as a number, not just "many."
- [ ] A comment at the top of the suppression file warns: "If your suppression has no expiry date it will be removed at next review."
**Validation commands:**
```bash
grep -c "expiry\|expires\|owner" docs/security/VULNERABILITY-SCAN.md
pip-audit 2>&1 | tail -5
```
**Risk notes:** Do not use this restructuring pass to remove legitimate suppressions. The goal is accountability, not a smaller list for its own sake. Some suppressions (e.g., dev-only test tools) are valid and should remain.

## Phase 4 — Electron Packaging and Bridge/Runtime Inclusion
*Goal: Produce an Electron package that includes the Python bridge scripts and can start and use the bridge on a clean install with no manual steps.*
---
### US-RR-018: Audit Electron package config against required bridge/runtime files
**Priority:** P0
**Description:** As a maintainer, I need a clear map of every file that `bridgeResolver.ts` expects at runtime in a packaged app, compared against what `gui/package.json` actually packages, so the gap is documented before any packaging fix is applied.
**Why it matters:** Codex found the Electron package resolves bridge scripts relative to the app directory, but `gui/package.json` does not include them in `extraResources`. Before fixing the config, the exact list of missing files must be established.
**Codex evidence:** "Electron package config omits the Python bridge/runtime it depends on: gui/package.json (line 48), gui/src/main/bridgeResolver.ts (line 53)."
**Files/areas involved:**
- `gui/package.json` (line 48, `extraResources` config)
- `gui/src/main/bridgeResolver.ts` (line 53, runtime path resolution)
- `bridge/*.py` (the scripts being resolved)
- `gui/src/main/index.ts` (any other bridge spawn calls)
**Acceptance Criteria:**
- [ ] `gui/src/main/bridgeResolver.ts` is read in full; every file path it constructs at runtime is documented.
- [ ] `gui/package.json` `extraResources` section is read; the list of files/directories included is documented.
- [ ] The gap (files resolved but not included) is listed explicitly.
- [ ] Whether a Python runtime (interpreter) is expected to be present on the user's machine or is bundled is documented.
- [ ] No files are changed in this story; output is a documented gap list that US-RR-019 will act on.
**Validation commands:**
```bash
cat gui/package.json | python -m json.tool | grep -A20 "extraResources"
grep -n "bridge\|resolve\|__dirname\|resourcesPath" gui/src/main/bridgeResolver.ts
grep -n "bridge\|spawn\|python" gui/src/main/index.ts | head -30
ls bridge/
```
**Risk notes:** The bridge may also depend on files in `rex/`, `config/`, or other directories. Check all `bridgeResolver.ts` and `index.ts` spawn calls, not just the bridge scripts themselves.
---
### US-RR-019: Fix `gui/package.json` `extraResources` to include bridge scripts
**Priority:** P0
**Description:** As a maintainer, I need `gui/package.json` to include the `bridge/*.py` scripts (and any other required runtime files identified in US-RR-018) in `extraResources`, so the packaged Electron app contains the files it needs to run.
**Why it matters:** Without this fix, a packaged app install cannot start the Python bridge. This is the most direct cause of Codex's deployment score of 25/100.
**Codex evidence:** "Electron package config omits the Python bridge/runtime it depends on: gui/package.json (line 48)."
**Files/areas involved:**
- `gui/package.json` (`extraResources` and `files` config)
- `gui/electron-builder.config.js` or `gui/electron-builder.yml` if present
**Acceptance Criteria:**
- [ ] `gui/package.json` `extraResources` includes a glob or explicit list covering all files identified in US-RR-018.
- [ ] `npm run build` in `gui/` completes without error.
- [ ] The packaged output directory contains `bridge/*.py` at the expected `extraResources` path (verify with `ls` or `find` in the packaged app directory).
- [ ] `bridgeResolver.ts` resolves paths that exist in the packaged output (verify by checking the path logic against the packaged directory structure).
- [ ] No required bridge file is absent from the packaged output.
**Validation commands:**
```bash
cd gui && npm run build
find gui/dist -name "*.py" 2>/dev/null | head -20
find gui/dist -path "*/bridge/*" | head -20
```
**Risk notes:** If the packaged app requires a Python interpreter on the user's PATH, document this requirement clearly in the installer README. If a bundled Python is required for a zero-dependency install, that is a larger effort and should be a separate story scoped to Phase 8.
---
### US-RR-020: Fix `bridgeResolver.ts` path resolution for packaged app context
**Priority:** P0
**Description:** As a maintainer, I need `gui/src/main/bridgeResolver.ts` to correctly resolve bridge script paths in both dev mode (relative to source) and packaged mode (relative to `process.resourcesPath`), so the bridge works in both contexts without manual path editing.
**Why it matters:** Codex found `bridgeResolver.ts` line 53 resolves from the app directory, which does not exist in the packaged `.asar`. If `extraResources` is fixed (US-RR-019) but the path resolution still points to the wrong directory in packaged mode, the bridge will still fail.
**Codex evidence:** "gui/src/main/bridgeResolver.ts (line 53) resolves the bridge path relative to the app directory, which does not exist in the packaged .asar."
**Files/areas involved:**
- `gui/src/main/bridgeResolver.ts` (line 53)
- `gui/src/main/index.ts` (any other bridge path construction)
**Acceptance Criteria:**
- [ ] `bridgeResolver.ts` checks `app.isPackaged` (or equivalent Electron API) and uses `process.resourcesPath` for the bridge script path in packaged mode.
- [ ] In dev mode, the resolver uses a path relative to the source tree (e.g., `../bridge/` from the project root).
- [ ] A comment explains both branches of the path resolution logic.
- [ ] TypeScript compilation passes: `npm run typecheck` in `gui/` returns no errors.
- [ ] The resolved path is logged at bridge startup so it can be inspected in packaged app logs.
**Validation commands:**
```bash
cd gui && npm run typecheck
grep -n "isPackaged\|resourcesPath\|__dirname" gui/src/main/bridgeResolver.ts
```
**Risk notes:** If `app.isPackaged` is not available at the point where `bridgeResolver.ts` runs, use `process.defaultApp` as a fallback. Test both code paths explicitly in US-RR-021.
---
### US-RR-021: Add a package smoke test proving clean install can start Electron and use the bridge
**Priority:** P0
**Description:** As a maintainer, I need an automated smoke test that installs the Electron app from the packaged output, launches it, and confirms the Python bridge is reachable, so packaging regressions are caught automatically.
**Why it matters:** Without a smoke test, packaging regressions are only caught by manual testing. Codex identified the packaging gap as a top-10 release blocker; the fix (US-RR-019 and US-RR-020) is only trustworthy with an automated verification path.
**Codex evidence:** "Electron package proves a clean install can start and use the bridge" is listed as a requirement in the ship-readiness checklist.
**Files/areas involved:**
- `gui/` (package output)
- A new test script, e.g., `tests/smoke/test_electron_package.sh` or a Jest/Playwright test in `gui/`
- `.github/workflows/ci.yml` (Phase 5 will wire this into CI)
**Acceptance Criteria:**
- [ ] A smoke test script exists at a documented path (e.g., `tests/smoke/test_electron_package.sh` or `gui/tests/smoke.test.ts`).
- [ ] The test: (1) builds the Electron package, (2) launches the packaged app in headless or minimal mode, (3) sends a bridge health-check request or waits for a startup signal, (4) asserts the bridge responded successfully, (5) exits the app cleanly.
- [ ] The test exits non-zero if the bridge is unreachable within a timeout.
- [ ] The test is documented in `README.md` or `docs/claude/TESTING_AND_QUALITY.md` under "Package Smoke Tests."
- [ ] Running the smoke test locally on a clean Python environment (without the source-tree `bridge/` on PATH) passes.
**Validation commands:**
```bash
bash tests/smoke/test_electron_package.sh
# or
cd gui && npx electron-builder --dir && node tests/smoke.js
```
**Risk notes:** Headless Electron testing requires a virtual display on Linux CI (`xvfb`). Document the CI display dependency. On macOS and Windows, code-signing may be required for packaged app launch; the smoke test may need to run on an unsigned build with a `--no-sandbox` or equivalent flag in CI.
---
## Phase 5 — CI/Release Gate Hardening
*Goal: Ensure CI gates every component of the shippable product, including GUI typecheck, build, Node audits, and Electron package smoke test.*
---
### US-RR-022: Add GUI TypeScript typecheck gate to CI
**Priority:** P1
**Description:** As a maintainer, I need CI to run `npm run typecheck` in `gui/` on every PR and merge to `master`, so TypeScript type errors in the Electron app are caught before they ship.
**Why it matters:** Codex confirmed the GUI typecheck passes locally but is not gated in CI. Type errors introduced on a branch will not be caught until a developer runs the check manually.
**Codex evidence:** "No GUI typecheck/build/package in main CI evidence inspected."
**Files/areas involved:**
- `.github/workflows/ci.yml`
- `gui/package.json` (typecheck script)
**Acceptance Criteria:**
- [ ] `.github/workflows/ci.yml` has a job or step that runs `cd gui && npm ci && npm run typecheck`.
- [ ] The step runs on every push to `master` and on every pull request targeting `master`.
- [ ] A failing typecheck returns a non-zero exit code and fails the CI run.
- [ ] The job is named clearly (e.g., `gui-typecheck`).
- [ ] The CI run currently passes (no pre-existing type errors are hidden by this gate addition).
**Validation commands:**
```bash
cd gui && npm ci && npm run typecheck
# After CI commit:
git push origin <branch> && # check GitHub Actions
```
**Risk notes:** If the current codebase has type errors that were previously undetected, fix them in this story or in a companion story before adding the gate. Do not add a gate that immediately fails due to pre-existing errors without fixing them.
---
### US-RR-023: Add GUI build gate to CI
**Priority:** P1
**Description:** As a maintainer, I need CI to run `npm run build` in `gui/` on every PR and merge to `master`, so build-breaking changes are caught before release.
**Why it matters:** A TypeScript typecheck can pass while the bundler still fails. The build step validates the full compile and bundling pipeline that produces the distributable.
**Codex evidence:** "No GUI typecheck/build/package in main CI evidence inspected."
**Files/areas involved:**
- `.github/workflows/ci.yml`
- `gui/package.json` (build script)
**Acceptance Criteria:**
- [ ] `.github/workflows/ci.yml` has a step that runs `cd gui && npm ci && npm run build`.
- [ ] The step runs on every push to `master` and on every pull request.
- [ ] Build artifacts are not uploaded unless on a release tag (to avoid bloating CI storage).
- [ ] A failing build returns a non-zero exit code and fails the CI run.
**Validation commands:**
```bash
cd gui && npm ci && npm run build
```
**Risk notes:** `npm run build` may fail without appropriate environment variables. Document any required `VITE_*` or `ELECTRON_*` env vars needed for a successful CI build and set them as CI secrets or defaults.
---
### US-RR-024: Add Node dependency audit gates to CI for `gui/` and `rex/ui/`
**Priority:** P1
**Description:** As a maintainer, I need CI to run `npm audit --audit-level=high` in both `gui/` and `rex/ui/` on every PR, so high-severity Node vulnerabilities are caught automatically.
**Why it matters:** Codex found both Node package directories have failing audits. Without a CI gate, new vulnerabilities introduced by dependency updates will go undetected.
**Codex evidence:** "npm audit results — gui/: 5 vulnerabilities (2 high, 3 moderate). rex/ui/: 3 moderate vulnerabilities."
**Files/areas involved:**
- `.github/workflows/ci.yml`
**Acceptance Criteria:**
- [ ] CI runs `cd gui && npm audit --audit-level=high` and fails if any high-severity vulnerabilities are present.
- [ ] CI runs `cd rex/ui && npm audit --audit-level=high` and fails if any high-severity vulnerabilities are present.
- [ ] Moderate vulnerabilities produce a warning but do not fail CI (or fail CI at `--audit-level=moderate` with documented suppressions in `.nsprc` or equivalent).
- [ ] The audit steps run after US-RR-015 and US-RR-016 remediation, so CI starts green for this gate.
**Validation commands:**
```bash
cd gui && npm audit --audit-level=high
cd rex/ui && npm audit --audit-level=high
```
**Risk notes:** If `npm audit` exits non-zero due to informational entries below the threshold, use `--audit-level=high` not `--audit-level=info` to avoid false failures.
---
### US-RR-025: Add Electron package smoke test gate to CI
**Priority:** P1
**Description:** As a maintainer, I need CI to run the Electron package smoke test from US-RR-021 on release tags and on PRs touching `gui/` or `bridge/`, so packaging regressions are caught automatically.
**Why it matters:** The smoke test from US-RR-021 is only useful if it runs automatically. Without a CI gate, a packaging regression can reach a release.
**Codex evidence:** "CI gates Python, Electron, dependency audits, and a package smoke test" is listed as a release candidate requirement.
**Files/areas involved:**
- `.github/workflows/ci.yml`
- `.github/workflows/release.yml` (if it exists)
- Smoke test script from US-RR-021
**Acceptance Criteria:**
- [ ] CI runs the package smoke test when: (a) a release tag is pushed, or (b) files in `gui/` or `bridge/` are changed in a PR.
- [ ] The smoke test step fails CI if the bridge is unreachable.
- [ ] The CI job documents any virtual display (`xvfb`) or platform requirements.
- [ ] CI passes a full green run after all Phase 4 fixes are applied.
**Validation commands:**
```bash
# On a PR touching gui/ or bridge/:
# GitHub Actions should trigger the smoke test job
bash tests/smoke/test_electron_package.sh
```
**Risk notes:** Electron package smoke tests are slow (2-5 minutes). Run them only on path-filtered triggers (not on every Python-only commit) to avoid slowing unrelated PRs.
---
### US-RR-026: Expand Python lint and type gate from changed-files-only to full repo
**Priority:** P1
**Description:** As a maintainer, I need CI to run `ruff check` and `mypy` across all Python files in the repo (not just changed files), and to reduce the list of core modules excluded from mypy, so type errors introduced anywhere in the codebase are caught.
**Why it matters:** Codex found `ci.yml` line 58 lints only changed files. A commit that adds a type error to an unchanged file (e.g., via a transitive import) will not be caught. Codex also found `pyproject.toml` line 390 excludes core modules from mypy.
**Codex evidence:** "Python lint/format only changed files: .github/workflows/ci.yml (line 58). Mypy runs, but core modules are ignored: pyproject.toml (line 390)."
**Files/areas involved:**
- `.github/workflows/ci.yml` (lint step)
- `pyproject.toml` (mypy `exclude` list, line 390)
**Acceptance Criteria:**
- [ ] CI lint step runs `ruff check .` on all Python files, not just `git diff` output.
- [ ] CI format step runs `black --check .` on all Python files.
- [ ] The mypy `exclude` list in `pyproject.toml` is reduced: at minimum, `rex/cli.py`, `rex/voice_loop.py`, and `rex/gui_app.py` are either included in mypy checking or have their exclusion documented with a ticket reference and a plan to re-enable.
- [ ] CI passes a full green run after this change (any pre-existing lint errors found by full-repo scan are fixed before the gate is activated).
- [ ] The lint and type steps complete in under 5 minutes (use mypy's incremental cache if needed).
**Validation commands:**
```bash
ruff check .
black --check .
mypy rex/ --ignore-missing-imports 2>&1 | tail -20
```
**Risk notes:** Enabling full-repo lint may surface pre-existing issues. Fix them in this story or document them as follow-up items. Do not disable the gate to hide pre-existing errors.
---
## Phase 6 — Runtime/Personal Data Cleanup and Secret/Config Consolidation
*Goal: Remove all tracked personal and demo runtime data. Establish one authoritative config/secret path.*
---
### US-RR-027: Remove tracked personal and demo runtime data from the repo
**Priority:** P0
**Description:** As a maintainer, I need `users.json`, `Memory/james/*`, `Memory/cole/*`, `profiles/james.json`, and any other personal or demo data to be removed from Git history and replaced with sanitized examples, so the repo does not leak personal information.
**Why it matters:** Codex found tracked personal profiles and memory data in the repo. Publishing the repo or distributing packages with this data is a privacy violation. It also creates onboarding confusion because new users cannot distinguish demo data from their own.
**Codex evidence:** "Tracked demo/personal runtime data: users.json and Memory/* content are tracked. Fix: Remove personal/demo runtime data; keep only sanitized examples."
**Files/areas involved:**
- `users.json`
- `Memory/james/*`
- `Memory/cole/*`
- `profiles/james.json`
- `profiles/default.json` (check for personal content)
- `.gitignore` (must be updated to exclude runtime data)
**Acceptance Criteria:**
- [ ] `users.json`, `Memory/james/*`, `Memory/cole/*`, and `profiles/james.json` are removed from the repo.
- [ ] If `profiles/default.json` contains personal content, it is replaced with a sanitized example using clearly fictional data.
- [ ] `.gitignore` is updated to exclude `users.json`, `Memory/`, and `profiles/*.json` (except `profiles/default.example.json`).
- [ ] A `profiles/default.example.json` or `Memory/README.md` is created with synthetic example data and a note explaining these files are generated at runtime.
- [ ] `git ls-files Memory/ profiles/ users.json` returns no personal files.
- [ ] The commit message explicitly states: "Remove tracked personal/demo runtime data."
- [ ] If a Git history rewrite is required to expunge previously committed personal data, it is coordinated with the repo owner and documented.
**Validation commands:**
```bash
git ls-files Memory/ profiles/ users.json
grep -r "james\|cole" Memory/ profiles/ 2>/dev/null | grep -v ".example."
cat .gitignore | grep -E "Memory|profiles|users.json"
```
**Risk notes:** If `users.json` or `Memory/` files are generated by the app at runtime, any existing users of the repo who have these files locally will have them ignored by `.gitignore` going forward, which is the correct behavior. Document this in the migration notes.
---
### US-RR-028: Fix the dead import of `rex.shopping_pwa` in `rex_speak_api.py`
**Priority:** P1
**Description:** As a developer, I need `rex_speak_api.py` to not import `rex.shopping_pwa` when only `archived/shopping_pwa/shopping_pwa.py` exists, so the TTS API starts without an `ImportError` on a clean install.
**Why it matters:** Codex found `rex_speak_api.py` imports `rex.shopping_pwa` but the module was archived. This is a startup error waiting to happen on any clean install that does not have the archived module restored.
**Codex evidence:** "Missing source for imported archived feature: rex_speak_api.py imports rex.shopping_pwa, but only archived/shopping_pwa/shopping_pwa.py is tracked."
**Files/areas involved:**
- `rex_speak_api.py` (import site)
- `archived/shopping_pwa/` (archived source)
- `rex/shopping_pwa.py` (check if this exists or is missing)
**Acceptance Criteria:**
- [ ] `rex_speak_api.py` does not import `rex.shopping_pwa` unconditionally.
- [ ] If the shopping PWA feature is still needed, the import is guarded with `try/except ImportError` and the feature is disabled gracefully when the module is absent.
- [ ] If the shopping PWA feature is not needed, the import and all references to it in `rex_speak_api.py` are removed.
- [ ] `python rex_speak_api.py --help` (or equivalent startup check) runs without `ImportError`.
- [ ] `python -c "import rex_speak_api"` succeeds without error.
**Validation commands:**
```bash
python -c "import rex_speak_api" 2>&1
grep -n "shopping_pwa\|shopping" rex_speak_api.py
```
**Risk notes:** If the shopping PWA is a planned future feature, leave a `# TODO` comment referencing the archived source rather than silently removing the import.
---
### US-RR-029: Consolidate secret storage to one protected authority
**Priority:** P1
**Description:** As a maintainer, I need secrets (JWT secret, HA token, Twilio credentials) to be stored in one protected location per deployment, not duplicated across `.env`, `config/rex_config.json`, and GUI settings, so secrets cannot drift and the attack surface for secret leakage is minimized.
**Why it matters:** Codex found the HA token is mirrored in both `.env` and GUI settings. Config sprawl means a secret rotation in one location may not propagate to another, leaving stale credentials in use.
**Codex evidence:** "Secrets stored/mirrored in plaintext config locations: HA token is stored in GUI settings and .env. Fix: Use OS credential storage or protected local secret file; avoid duplicate secret stores."
**Files/areas involved:**
- `rex/config.py` (config loading)
- `rex/auth.py` (JWT secret loading)
- `rex/ha_bridge.py` (HA token loading)
- `rex/telephony/twilio_handler.py` (Twilio credential loading)
- `config/rex_config.json` (check for any secret storage)
- `gui/src/main/index.ts` (GUI settings that store credentials)
- `docs/claude/CONFIG_AND_SECURITY.md`
**Acceptance Criteria:**
- [ ] A single canonical secret-loading path is defined: secrets come from the OS keyring (via `keyring` library) OR from `.env` only, never from `rex_config.json` or GUI settings files.
- [ ] `config/rex_config.json` contains no secrets or credentials — only non-sensitive settings.
- [ ] GUI settings do not store or mirror secrets; when HA credentials are needed, they are retrieved from the canonical secret store at runtime.
- [ ] The migration path for existing users who have secrets in `rex_config.json` or GUI settings is documented in `docs/claude/CONFIG_AND_SECURITY.md`.
- [ ] `grep -r "ha_token\|HA_TOKEN\|jwt.*secret\|twilio.*auth" config/rex_config.json` returns no matches.
**Validation commands:**
```bash
grep -rn "ha_token\|HA_TOKEN\|jwt_secret\|twilio.*auth\|TWILIO.*AUTH" config/ rex_config*.json 2>/dev/null
python -c "from rex.config import AppConfig; c = AppConfig(); print('ok')"
```
**Risk notes:** OS keyring access requires `pip install keyring` and platform-specific backend libraries (`keyrings.alt` on Linux). If keyring is not available, fall back to `.env` only, not to plaintext JSON. Document the fallback clearly.
---
### US-RR-030: Audit and document the complete config authority chain
**Priority:** P1
**Description:** As a maintainer, I need a documented map of every configuration key, where it is read from (`.env`, `rex_config.json`, GUI settings, environment, CLI arg), and which source takes precedence, so developers and users have one authoritative reference for config behavior.
**Why it matters:** Codex found config spread across `.env`, `config/rex_config.json`, profiles, GUI settings, and env mirroring makes it impossible to reason about the effective config at runtime. This is a prerequisite for US-RR-029 and for first-run UX work in Phase 8.
**Codex evidence:** "Config is scattered: .env, config/rex_config.json, profiles, GUI settings, env mirroring. Secrets and behavior can drift across surfaces."
**Files/areas involved:**
- `rex/config.py`
- `docs/claude/CONFIG_AND_SECURITY.md`
- `config/rex_config.json`
- `.env.example`
**Acceptance Criteria:**
- [ ] `docs/claude/CONFIG_AND_SECURITY.md` contains a table listing every `AppConfig` field, its source priority (env > config JSON > default), and whether it is a secret, a runtime setting, or an optional feature flag.
- [ ] Any config key that currently has conflicting sources (env and JSON) is resolved to one winner with documented precedence.
- [ ] The `AppConfig` sub-config access pattern from `CLAUDE.md` is reflected in the doc (all seven sub-config objects: `audio`, `voice`, `llm`, `tools`, `integrations`, `ui`, `security`).
- [ ] The doc warns against adding new flat top-level `AppConfig` fields (per `CLAUDE.md`).
**Validation commands:**
```bash
python -c "from rex.config import AppConfig; import json; c = AppConfig(); print([f for f in dir(c) if not f.startswith('_')])"
grep -c "config\." docs/claude/CONFIG_AND_SECURITY.md
```
**Risk notes:** This is a documentation story, not a code change. Do not refactor `AppConfig` in this story; the goal is to understand and document the current behavior accurately.
---
## Phase 7 — Release Surface Consolidation and Legacy Classification
*Goal: Classify every runtime/UI surface. Disable or hide non-shipping surfaces from the packaged Electron app.*
---
### US-RR-031: Classify every runtime/UI surface as shippable, developer-only, deprecated, archived, or removed
**Priority:** P1
**Description:** As a product owner, I need every entry point and UI surface in the repo to have an explicit classification so that packaging, docs, CI, and support scope are clear.
**Why it matters:** Codex identified this as a root cause of the sprawl problem. Without explicit classification, every surface is implicitly treated as release-critical, multiplying the security surface, packaging complexity, and support burden.
**Codex evidence:** "Architecture has too many parallel runtime/UI surfaces: gui/, rex-gui, rex/ui, archived/, root shims, bridge scripts. Single biggest architectural risk: parallel runtime surfaces."
**Files/areas involved:**
- `pyproject.toml` (entry points)
- `gui/` (Electron app)
- `rex/gui_app.py` (Flask GUI/API)
- `rex/ui/` (alternative UI)
- `archived/` (retired code)
- Root-level compatibility shims
- `CLAUDE.md` (must be updated with surface classification)
- `README.md`
**Acceptance Criteria:**
- [ ] A `SURFACE-CLASSIFICATION.md` is created at the repo root with a table covering every entry point and UI surface listed in the Codex repo map.
- [ ] Each surface is assigned exactly one of: `shippable` (included in packaged Electron app), `developer-only` (available via source install, not packaged), `deprecated` (no new use, planned removal date), `archived` (in `archived/`, not maintained), `removed` (deleted in this PR).
- [ ] The Electron app (`gui/`) is classified as `shippable`.
- [ ] `rex/ui/` is classified (likely `developer-only` or `deprecated` — do not decide here, but do assign a classification after reading the code).
- [ ] `archived/` content is classified as `archived`.
- [ ] Root-level compatibility shims are classified as `developer-only` or `deprecated`.
- [ ] `CLAUDE.md` is updated to reference `SURFACE-CLASSIFICATION.md`.
**Validation commands:**
```bash
cat SURFACE-CLASSIFICATION.md
grep -c "shippable\|developer-only\|deprecated\|archived\|removed" SURFACE-CLASSIFICATION.md
```
**Risk notes:** Classification decisions have downstream consequences for packaging (Phase 4), CI (Phase 5), and docs (Phase 9). Make classification decisions based on actual code inspection, not assumptions. If a surface's status is genuinely unclear, classify it as `developer-only` until a human owner decides.
---
### US-RR-032: Disable non-shipping Flask GUI dashboard from packaged Electron app
**Priority:** P1
**Description:** As a maintainer, I need the Flask GUI/API dashboard (`rex-gui`, `rex/gui_app.py`) to not be started automatically inside the packaged Electron app unless it is classified as shippable, so users of the Electron app are not exposed to the Flask API surface.
**Why it matters:** If the Electron app spawns `rex-gui` as a subprocess, all the unauthenticated Flask routes found in Phase 2 are reachable from within the packaged app. If the Flask dashboard is developer-only, it must not run in the packaged context.
**Codex evidence:** "Architecture has too many active surfaces. Flask dashboard, archived UI/PWA surfaces... should be classified as keep/developer-only/deprecate/archive/remove."
**Files/areas involved:**
- `gui/src/main/index.ts` (any subprocess spawning of `rex-gui` or Flask)
- `bridge/*.py` (bridge scripts may start Flask)
- `rex/gui_app.py`
**Acceptance Criteria:**
- [ ] `gui/src/main/index.ts` and all bridge scripts are audited for any subprocess spawn of `rex-gui`, `flask`, or `rex/gui_app.py`.
- [ ] If the packaged app spawns the Flask GUI, a feature flag or build-time exclude is added so it does not spawn in packaged mode unless `rex-gui` is explicitly classified as `shippable`.
- [ ] The smoke test from US-RR-021 confirms the Flask GUI routes are not reachable from the packaged app unless explicitly enabled.
- [ ] `SURFACE-CLASSIFICATION.md` is updated with the final decision for `rex-gui`.
**Validation commands:**
```bash
grep -n "rex-gui\|gui_app\|flask\|subprocess" gui/src/main/index.ts bridge/*.py
```
**Risk notes:** If the Flask GUI is the primary API backend for the Electron app (i.e., the Electron renderer calls Flask REST endpoints), then `rex/gui_app.py` is shippable and must remain — but all unauthenticated routes from Phase 2 must still be fixed. Clarify this dependency before classifying the surface.

### US-RR-033: Clean up root-level compatibility shims and legacy Tkinter references
**Priority:** P2
**Description:** As a maintainer, I need root-level compatibility shim files that re-export from the canonical package to be either documented as permanent shims or scheduled for removal, and all Tkinter/legacy UI references in docs and code to be removed or updated.
**Why it matters:** Codex found root-level shims like `voice_loop.py`, `llm_client.py`, and `config.py` re-export from `rex.*` canonical paths. These add confusion for developers reading the codebase and may mask import errors.
**Codex evidence:** "Obsolete/experimental/confusing surfaces: archived/, rex/ui/, root-level compatibility shims, incomplete rex-gui browser dashboard, old Tkinter references."
**Files/areas involved:**
- Root `voice_loop.py`, `llm_client.py`, `config.py` (shim files)
- Any doc references to Tkinter or old GUI
- `CLAUDE.md` (already documents `voice_loop.py` shim behavior)
**Acceptance Criteria:**
- [ ] Each root-level shim file has a module-level comment: "Compatibility shim. Canonical implementation: rex.<module>. Scheduled for removal in [version/phase]."
- [ ] All references to Tkinter UI (`gui.py` deprecated, `rex-gui` browser confusion) are removed from `README.md` and docs.
- [ ] `grep -rn "tkinter\|Tkinter\|gui.py" docs/ README.md` returns no results (except in the context of deprecation notices).
- [ ] `CLAUDE.md` is updated if the shim documentation there is stale.
**Validation commands:**
```bash
grep -rn "tkinter\|Tkinter" . --include="*.py" --include="*.md" | grep -v "archived/"
grep -n "DeprecationWarning" voice_loop.py llm_client.py config.py
```
**Risk notes:** Do not delete the shim files in this story. Per "Do Not Do Yet," deletion must follow classification (Phase 7) and update of all references. This story only adds comments and cleans docs.
---
## Phase 8 — First-Run/Reset/Recovery Tests and Package Smoke Tests
*Goal: Prove the first-run experience is safe, the reset flow works, and config migration does not lose data.*
---
### US-RR-034: Add negative security tests for auth and privileged routes
**Priority:** P1
**Description:** As a security engineer, I need automated negative tests confirming that each security fix in Phase 2 is enforced, so regressions in auth, HA, and Twilio protection are caught by the test suite.
**Why it matters:** Codex found no negative security tests for missing JWT secret, unauthenticated logs, setup/register behavior, and HA secret enforcement. Security fixes without regression tests are fragile.
**Codex evidence:** "Minimum test suite before shipping: Auth/security — Negative tests for missing JWT secret, setup CSRF/origin, logs auth, HA secret. HA controls — Tests proving no HA state/script route is reachable without auth/secret."
**Files/areas involved:**
- `tests/test_auth.py` (or new `tests/security/test_negative_auth.py`)
- `tests/test_ha_bridge.py` (or new file)
- `tests/test_ph001_twilio_handler.py`
**Acceptance Criteria:**
- [ ] Test: Starting auth with no `REX_JWT_SECRET` set either raises `RuntimeError` or generates a local secret (not the default string). Asserts the forged-token string `rex-insecure-default-secret` is never accepted.
- [ ] Test: `GET /log` without auth returns 401 or 403.
- [ ] Test: `POST /setup` without the setup token or from a non-Electron origin returns 401 or 403.
- [ ] Test: `POST /register` without the setup token or from a non-Electron origin returns 401 or 403.
- [ ] Test: `GET /ha/entities` without `HA_SECRET` set returns 404 (routes not mounted) or 403.
- [ ] Test: `GET /ha/script` without `HA_SECRET` set returns 404 or 403.
- [ ] Test: Twilio signature validation with package missing returns `False`.
- [ ] Test: Voicemail route without valid Twilio signature returns 403.
- [ ] All tests above are in `tests/` and collected by `pytest --collect-only` without error.
- [ ] `pytest tests/security/ -q -v` (or equivalent path) passes.
**Validation commands:**
```bash
pytest tests/ -k "negative or auth or ha_secret or twilio_missing or log_auth" -q -v
pytest --collect-only -q 2>&1 | grep "security\|negative" | head -20
```
**Risk notes:** Some of these tests require a running Flask app. Use pytest fixtures with `app.test_client()` rather than a real server process. Ensure fixtures properly reset `HA_SECRET` between tests using `monkeypatch` or `unittest.mock.patch`.
---
### US-RR-035: Add first-run setup flow tests
**Priority:** P1
**Description:** As a maintainer, I need automated tests covering the first-run setup flow — secret creation, setup wizard, and startup persistence — so regressions in the initial user experience are caught.
**Why it matters:** Codex found the first-run flow has a security race risk (unauthenticated setup endpoint, fixed in Phase 2) and no existing tests proving the flow works end-to-end after setup.
**Codex evidence:** "First-run UX: Setup wizard race, secret creation, restart persistence" listed in minimum test coverage.
**Files/areas involved:**
- `tests/` (new test file: `tests/test_first_run.py`)
- `rex/gui_app.py` (setup route)
- `rex/auth.py` (secret generation)
**Acceptance Criteria:**
- [ ] Test: On a clean state (no `users.json`, no `REX_JWT_SECRET`), the first-run setup endpoint completes successfully and creates a user.
- [ ] Test: After setup, the created user can authenticate and receive a valid JWT.
- [ ] Test: A second attempt to run setup after a user exists returns an appropriate error (setup is one-time).
- [ ] Test: If a generated JWT secret is stored locally, it is present after a simulated app restart (read back from the same path).
- [ ] All tests are collected without error.
- [ ] `pytest tests/test_first_run.py -q` passes.
**Validation commands:**
```bash
pytest tests/test_first_run.py -q -v
pytest --collect-only -q 2>&1 | grep "first_run"
```
**Risk notes:** Tests that touch `users.json` or the secret file must use `tmp_path` fixtures to avoid polluting the real user's data. Use `monkeypatch` to redirect file paths to temporary directories.
---
### US-RR-036: Add config migration and reset/recovery tests
**Priority:** P2
**Description:** As a maintainer, I need automated tests covering config migration (upgrading from an older `rex_config.json` schema) and reset/recovery (what happens when the config file is missing, corrupt, or from a previous major version).
**Why it matters:** Codex found "Upgrade/reset: Existing config/data migration behavior" in the minimum test coverage list. Without migration tests, config schema changes can silently break existing installs.
**Codex evidence:** "Upgrade/reset — Existing config/data migration behavior" listed in minimum test coverage.
**Files/areas involved:**
- `rex/config.py` (migration logic)
- `rex-config` CLI entry point (`rex.config:cli`)
- `tests/` (new test file: `tests/test_config_migration.py`)
**Acceptance Criteria:**
- [ ] Test: Loading a `rex_config.json` from a previous schema version (simulate by omitting a new required field) either migrates gracefully with defaults or raises a clear `ConfigError`, not an unhandled `KeyError`.
- [ ] Test: A corrupt `rex_config.json` (invalid JSON) results in a `ConfigError` with a helpful message pointing to the file path.
- [ ] Test: A missing `rex_config.json` results in defaults being applied, not a crash.
- [ ] Test: `rex-config migrate` (or equivalent CLI) produces a valid config from an old-format input.
- [ ] All tests are collected without error.
- [ ] `pytest tests/test_config_migration.py -q` passes.
**Validation commands:**
```bash
pytest tests/test_config_migration.py -q -v
python -m rex config --help 2>&1
```
**Risk notes:** If no migration logic exists yet in `rex/config.py`, this story adds it. The minimum requirement is: missing keys get safe defaults; corrupt files raise a clear error; missing file uses defaults.
---
## Phase 9 — Documentation Truth Pass
*Goal: Ensure docs reflect the actual supported install/run path and do not contain misleading or dangerous instructions.*
---
### US-RR-037: Update README to declare one supported install/run path and deprecate others
**Priority:** P1
**Description:** As a maintainer, I need the README to clearly declare the Electron + Python bridge as the one supported user-facing install path, and to demote all other paths (CLI voice loop, Flask dashboard, TTS API as standalone, etc.) to "Developer / Advanced" sections.
**Why it matters:** Codex found the README is honest about alpha status but lists multiple runtime paths (8+ entry points) without a clear hierarchy. A non-technical user cannot determine which path to follow.
**Codex evidence:** "A non-technical user does not have a clear safe installer, credential storage model, recovery/reset flow... or single supported GUI path."
**Files/areas involved:**
- `README.md`
- `INSTALL.md`
- `docs/`
**Acceptance Criteria:**
- [ ] The README has a prominent "Getting Started" section that describes only the Electron app install path.
- [ ] All other runtime paths (CLI, voice loop, Flask dashboard, TTS API, Windows agent, OpenClaw tool server) are in a collapsible or clearly separated "Advanced / Developer" section.
- [ ] The README does not contain `change-me` or other placeholder secrets in user-facing setup instructions.
- [ ] The alpha warning from `README.md` line 16 is preserved (it is accurate).
- [ ] Known limitations from the README (wake-word latency, Outlook partial, per-user isolation incomplete) are preserved and not removed.
- [ ] Docs are consistent: if `INSTALL.md` describes a different primary path, it is updated to match the README.
**Validation commands:**
```bash
grep -n "change-me\|CHANGE_ME\|your-secret-here" README.md INSTALL.md docs/
grep -n "Getting Started\|Quick Start\|Install" README.md | head -10
```
**Risk notes:** Do not remove honest alpha/limitation notices from the README. The goal is clarity about the supported path, not false marketing.
---
### US-RR-038: Remove or replace placeholder secrets in all documentation
**Priority:** P1
**Description:** As a maintainer, I need all placeholder secrets (`change-me`, `your-token-here`, etc.) in documentation and example configs to be replaced with clearly fictional values and generation instructions, so users do not accidentally copy placeholder values into production configs.
**Why it matters:** Codex flagged `change-me` placeholder secrets as acceptable for developer docs but bad for consumer-facing setup. Users who copy example configs verbatim will have insecure defaults.
**Codex evidence:** "Docs also include placeholder secrets like change-me, which are acceptable for developer docs but bad for consumer-facing setup."
**Files/areas involved:**
- `README.md`
- `INSTALL.md`
- `.env.example`
- `docs/` (all markdown files)
- `config/rex_config.json` (example values)
**Acceptance Criteria:**
- [ ] Every user-facing doc that shows a secret value either: (a) shows a generation command (`python -c "import secrets; print(secrets.token_hex(32))"`) instead of a placeholder, or (b) uses a clearly bracketed placeholder (`<YOUR_STRONG_SECRET_HERE>`, not `change-me`).
- [ ] `.env.example` has generation commands for `REX_JWT_SECRET` and any other required secrets.
- [ ] `grep -rn "change-me\|CHANGE_ME\|changeme\|your.*token\|your.*secret\|placeholder" docs/ README.md INSTALL.md .env.example` returns no matches in user-facing install instructions.
- [ ] Developer-only docs (e.g., `docs/claude/`) may retain `change-me` if they are clearly scoped to developers and include a warning.
**Validation commands:**
```bash
grep -rn "change-me\|CHANGE_ME\|changeme" docs/ README.md INSTALL.md .env.example
grep -n "REX_JWT_SECRET" .env.example
```
**Risk notes:** Do not remove the example config files; they are valuable for developer onboarding. Only fix the values inside them.
---
### US-RR-039: Update docs to reflect surface classification and deprecation decisions
**Priority:** P2
**Description:** As a maintainer, I need all docs (README, INSTALL, integration guides, `CLAUDE.md`) to reflect the surface classification decisions from Phase 7, so deprecated or developer-only surfaces are no longer presented as primary options.
**Why it matters:** Docs that contradict classification decisions create confusion and cause users to attempt unsupported paths.
**Codex evidence:** "Documentation: README is honest but onboarding is not production-grade. Single supported user-facing path declared."
**Files/areas involved:**
- `README.md`
- `docs/` (all files)
- `CLAUDE.md`
- `SURFACE-CLASSIFICATION.md` (created in US-RR-031)
**Acceptance Criteria:**
- [ ] Every surface classified as `deprecated` in `SURFACE-CLASSIFICATION.md` has a deprecation notice in any doc that references it.
- [ ] Every surface classified as `developer-only` is in a Developer section of the relevant doc, not in user-facing Getting Started.
- [ ] Every surface classified as `archived` is mentioned only in `archived/ARCHIVED.md`, not in primary docs.
- [ ] `CLAUDE.md` Tech Stack section matches the final surface classification.
- [ ] Docs do not contradict each other on which path is primary.
**Validation commands:**
```bash
grep -rn "rex-gui\|rex/ui\|archived" README.md docs/ | grep -v "archived/ARCHIVED.md"
diff <(grep -h "Surface\|Entry" SURFACE-CLASSIFICATION.md) <(grep -h "Entry point" README.md) | head -20
```
**Risk notes:** This is a documentation-only story. Do not change code. Do not delete docs without confirming no other doc links to them.
---
## Phase 10 — Post-Release Technical Debt Cleanup
*Goal: Decompose giant mixed-concern modules only after all P0/P1 stories are complete and CI is green.*
> **Prerequisite:** Do not begin any Phase 10 story until: full pytest suite passes, all P0/P1 security fixes are merged, CI is green on all gates, and a release candidate has been tagged or is within one sprint of tagging.
---
### US-RR-040: Decompose `rex/gui_app.py` by route domain
**Priority:** P3
**Description:** As a maintainer, I need `rex/gui_app.py` (52 KB, mixed-concern) decomposed into route-domain Blueprint modules (e.g., `rex/routes/auth.py`, `rex/routes/ha.py`, `rex/routes/logs.py`, `rex/routes/setup.py`), so the file is reviewable and changes are isolated to their domain.
**Why it matters:** Codex identified `rex/gui_app.py` at 52 KB as a high-maintenance-risk file. Mixed concerns make every security review and change harder to reason about.
**Codex evidence:** "Giant mixed-concern files: rex/gui_app.py 52 KB. Code quality risk: Mixed responsibilities."
**Files/areas involved:**
- `rex/gui_app.py`
- New `rex/routes/` package
**Acceptance Criteria:**
- [ ] `rex/gui_app.py` is under 200 lines after extraction (app factory, middleware registration, blueprint registration only).
- [ ] Each route domain has its own Blueprint module in `rex/routes/`.
- [ ] All existing tests pass without modification.
- [ ] `ruff check rex/gui_app.py rex/routes/` passes.
- [ ] `mypy rex/gui_app.py rex/routes/` passes (no new type: ignore).
- [ ] No behavior change: the route table before and after decomposition is identical.
**Validation commands:**
```bash
wc -l rex/gui_app.py
pytest tests/ -q
ruff check rex/gui_app.py rex/routes/
```
**Risk notes:** This is the highest-risk decomposition story. Do it last, with the full test suite green. Use `git diff` to confirm no route paths, methods, or decorators changed during extraction.
---
### US-RR-041: Decompose `rex/cli.py` by command domain
**Priority:** P3
**Description:** As a maintainer, I need `rex/cli.py` (182 KB) decomposed into focused command modules so individual CLI commands can be reviewed, tested, and modified without touching the entire CLI.
**Why it matters:** Codex identified `rex/cli.py` as the largest file at 182 KB — far beyond any reasonable single-file scope.
**Codex evidence:** "Giant mixed-concern files: rex/cli.py 182 KB."
**Files/areas involved:**
- `rex/cli.py`
- New `rex/commands/` package (or equivalent)
**Acceptance Criteria:**
- [ ] `rex/cli.py` is under 300 lines after extraction (Click group registration only).
- [ ] Each command domain has its own module.
- [ ] All CLI commands work identically after decomposition.
- [ ] `pytest tests/ -q` passes.
- [ ] `rex --help` and `rex <subcommand> --help` outputs are unchanged.
**Validation commands:**
```bash
wc -l rex/cli.py
rex --help
pytest tests/ -q
```
**Risk notes:** Decomposing Click command groups requires care with group nesting and context propagation. Test every subcommand after decomposition.
---
### US-RR-042: Decompose `rex/voice_loop.py` by concern
**Priority:** P3
**Description:** As a maintainer, I need `rex/voice_loop.py` (128 KB) decomposed into focused modules (wake-word handling, STT, TTS, LLM routing, session state) so the voice pipeline can be individually tested and modified.
**Why it matters:** Codex identified `rex/voice_loop.py` as 128 KB of mixed voice-pipeline concerns.
**Codex evidence:** "Giant mixed-concern files: rex/voice_loop.py 128 KB."
**Files/areas involved:**
- `rex/voice_loop.py`
- `rex/wakeword/` (already exists — integrate)
- New concern-specific modules as needed
**Acceptance Criteria:**
- [ ] `rex/voice_loop.py` is under 200 lines after extraction.
- [ ] The voice loop integration test (if any) passes.
- [ ] `pytest tests/ -q` passes.
- [ ] `python rex_loop.py --help` (or equivalent startup check) runs without error.
**Validation commands:**
```bash
wc -l rex/voice_loop.py
pytest tests/ -q
python -c "from rex.voice_loop import build_voice_loop; print('ok')"
```
**Risk notes:** Per `CLAUDE.md`: "The canonical wake-word implementation is `rex/wakeword/`." Do not re-introduce root-level shim behavior during decomposition.
---
### US-RR-043: Decompose `gui/src/main/index.ts` by concern
**Priority:** P3
**Description:** As a maintainer, I need `gui/src/main/index.ts` (1500+ lines) decomposed into focused modules (window management, IPC handlers, bridge lifecycle, integration setup) so Electron main process code is maintainable.
**Why it matters:** Codex found `gui/src/main/index.ts` handles Electron windowing, env files, HA, integrations, secrets, and IPC in a single file. A regression in any one area requires reading the entire file.
**Codex evidence:** "Mixed responsibilities: gui/src/main/index.ts handles Electron windowing, env files, HA, integrations, secrets, IPC."
**Files/areas involved:**
- `gui/src/main/index.ts`
- New `gui/src/main/` submodules
**Acceptance Criteria:**
- [ ] `gui/src/main/index.ts` is under 200 lines after extraction.
- [ ] `npm run typecheck` in `gui/` passes.
- [ ] `npm run build` in `gui/` produces a valid build.
- [ ] The smoke test from US-RR-021 passes.
**Validation commands:**
```bash
wc -l gui/src/main/index.ts
cd gui && npm run typecheck && npm run build
bash tests/smoke/test_electron_package.sh
```
**Risk notes:** IPC handler decomposition must preserve all channel names and argument shapes. Any change to an IPC channel name will break the renderer. Test every IPC-dependent feature after decomposition.
---
### US-RR-044: Remove broad mypy core-module exclusions and fix resulting type errors
**Priority:** P3
**Description:** As a maintainer, I need the mypy `exclude` entries for core modules in `pyproject.toml` to be removed one module at a time, with any newly surfaced type errors fixed, so the type coverage gate is meaningful.
**Why it matters:** Codex found `pyproject.toml` line 390 excludes core modules from mypy. A type gate that excludes the most complex modules provides false assurance.
**Codex evidence:** "Mypy runs, but core modules are ignored: pyproject.toml (line 390). Weak typing gate."
**Files/areas involved:**
- `pyproject.toml` (mypy exclude list)
- Core modules re-enabled: `rex/cli.py`, `rex/voice_loop.py`, `rex/gui_app.py`
**Acceptance Criteria:**
- [ ] Each excluded core module is re-enabled in mypy one at a time.
- [ ] All type errors surfaced by re-enabling each module are fixed (not suppressed with `type: ignore` unless a third-party library requires it).
- [ ] `mypy rex/` returns 0 errors after all core modules are re-enabled.
- [ ] CI mypy step (from US-RR-026) passes with the expanded scope.
**Validation commands:**
```bash
mypy rex/ --ignore-missing-imports 2>&1 | grep "error:" | wc -l
mypy rex/cli.py rex/voice_loop.py rex/gui_app.py --ignore-missing-imports 2>&1 | tail -20
```
**Risk notes:** This story is intentionally last. Giant modules must be decomposed (US-RR-040 through US-RR-043) before their type errors are tractable. Do not begin this story until decomposition is complete.
---
## Definition of Release Candidate
The following checklist must be fully satisfied before any public release is cut. Every item must be confirmed by automated test or CI gate output — not by manual assertion.
### Test Suite
- [ ] `pytest --collect-only -q` completes with 0 errors.
- [ ] `pytest -q` passes with 0 failures on a clean checkout with only base dependencies installed.
- [ ] All negative security tests (US-RR-034) pass.
- [ ] First-run setup flow tests (US-RR-035) pass.
### Dependency Audits
- [ ] `pip-audit` returns 0 runtime vulnerabilities, or all remaining findings have narrow suppression entries with owner, rationale, risk tier, and expiry date.
- [ ] `npm audit --audit-level=high` in `gui/` returns 0 high-severity vulnerabilities.
- [ ] `npm audit --audit-level=high` in `rex/ui/` returns 0 high-severity vulnerabilities.
- [ ] The `pip-audit` suppression list has fewer than [baseline - 10] entries, all with expiry dates.
### Security
- [ ] `grep -r "rex-insecure-default-secret" .` returns no results.
- [ ] Starting the app with `REX_JWT_SECRET` unset either raises an error or generates a local secret — it never uses a known default.
- [ ] `GET /log` without auth returns 401 or 403 (automated test passing).
- [ ] `POST /setup` and `POST /register` without setup token return 401 or 403 (automated test passing).
- [ ] `GET /ha/entities` and `GET /ha/script` without `HA_SECRET` return 404 or 403 (automated test passing).
- [ ] Twilio signature validation returns `False` when `twilio` package is missing (automated test passing).
- [ ] Voicemail route without valid Twilio signature returns 403 (automated test passing).
### Electron Packaging
- [ ] The smoke test from US-RR-021 passes on a clean machine (no source tree bridge on PATH).
- [ ] `find gui/dist -name "*.py"` returns bridge scripts in the packaged output.
- [ ] `bridgeResolver.ts` path resolution uses `process.resourcesPath` in packaged mode.
### CI Gates
- [ ] CI runs `ruff check .` on all Python files (not just changed files) and fails on errors.
- [ ] CI runs `npm run typecheck` in `gui/` and fails on errors.
- [ ] CI runs `npm run build` in `gui/` and fails on errors.
- [ ] CI runs `npm audit --audit-level=high` in `gui/` and `rex/ui/` and fails on high-severity findings.
- [ ] CI runs the Electron package smoke test on PRs touching `gui/` or `bridge/`.
- [ ] CI runs `pip-audit` with the restructured suppression config and fails on any runtime vulnerability not suppressed.
### Data and Secrets
- [ ] `git ls-files Memory/ profiles/james.json users.json` returns no results.
- [ ] `.gitignore` excludes `users.json`, `Memory/`, and non-example profiles.
- [ ] `grep -r "change-me\|CHANGE_ME" README.md INSTALL.md .env.example docs/` returns no matches in user-facing install instructions.
- [ ] `config/rex_config.json` contains no secrets or credentials.
### Surface Consolidation
- [ ] `SURFACE-CLASSIFICATION.md` exists and classifies every entry point and UI surface.
- [ ] The packaged Electron app does not start the Flask GUI dashboard unless it is classified as `shippable`.
- [ ] README has one primary Getting Started section pointing to the Electron app.
- [ ] All deprecated surfaces have deprecation notices in their docs.
### Docker (if Docker is part of the release)
- [ ] The Docker healthcheck at `Dockerfile` line 85 validates actual service readiness (not always-exit-0).
