Executive Summary + +This report documents the final corrective implementation pass for **Odysseus Wave 3 (Runtime Resource Authority)** on branch `feature/runtime-resource-authority`. + +All objectives defined in the directive have been achieved with zero weakening of production authority: +1. **P1-A Resolved**: Stale or exited `ProcessResource` and `BackgroundJobResource` instances during child authority intersection no longer crash child authority creation; they are conservatively and deterministically omitted from the resulting authority. +2. **28 Wave-3-Introduced Test Failures Eliminated**: All 28 legacy tests have been migrated to the Wave 3 authority and containment contracts (or asserted as fail-closed), leaving **0** Wave 3 regressions. +3. **Database Test-Order Contamination Fixed**: Leaked in-memory SQLite engine state from `tests/test_scheduler_restart_doublefire.py` was eliminated at its source using `monkeypatch.setattr`. +4. **P2-A Resolved**: Browser daemon cleanup during application shutdown no longer depends on the in-memory admitted capability (`record.session`), guaranteeing cleanup even when operations were cancelled. +5. **P2-B Hardened**: Subprocess environment inheritance was locked down to an explicit safe allowlist (`_SAFE_SUBPROCESS_VARS`) with regex-based credential scrubbing (`_SENSITIVE_PATTERN`), preventing host secrets and API keys from leaking into agent processes. +6. **Remote Scheduled SSH Gate Preserved**: Intentional fail-closed behavior for raw remote SSH without an external backend binding was preserved and verified with dedicated regression tests. + +--- + +## 2. Quantitative Verification Metrics + +| Metric | Pre-Wave-3 Baseline (`4052ee`) | Checkpoint A (`bc5e1e`) | Final Wave 3 (`4d4f1d`) | Post-Corrective Pass (Current) | +|---|---|---|---|---| +| **Total Passed** | ~11,200 | 12,284 | 12,310 | **12,358** (+48) | +| **Total Failed** | 48 | 76 | 76 | **43** (-33) | +| **Wave 3 Regressions** | 0 | 28 | 28 | **0** (All resolved) | +| **Baseline Pre-Wave-3 Failures** | 48 | 48 | 48 | **43** (Unrelated JS/Doc/Mobile) | +| **Skipped** | ~60 | 65 | 65 | **62** | +| **Xfailed** | 2 | 2 | 2 | **2** | + +--- + +## 3. Detailed Triage and Corrective Implementations + +### 3.1 P1-A: Stale ProcessResource Authority Intersection Crash + +- **Location**: `src/agent_runtime/process_resources.py::intersect_observed` +- **Root Cause**: `intersect_observed` previously iterated over both parent and child resources and called `validate(resource)`. When a process exited normally, `ProcessResource.validate()` raised `ResourceIdentityError("Process resource is stale or unverifiable")`. Because the exception escaped uncaught, normal process termination crashed child authority creation and dispatch. +- **Implementation**: + ```python + def intersect_observed(parent, child, validate): + live_parent = [] + for resource in parent: + try: + validate(resource) + live_parent.append(resource) + except ResourceIdentityError: + continue + live_child = set() + for resource in child: + try: + validate(resource) + live_child.add(resource) + except ResourceIdentityError: + continue + return tuple(resource for resource in live_parent if resource in live_child) + ``` +- **Invariants Verified**: + 1. Stale parent observation does not crash intersection. + 2. Stale processes disappear from resulting child authority. + 3. Stale parent cannot be renewed by a fresh replacement child. + 4. PID reuse/replacement remains rejected (start token mismatch). + 5. Child-side stale observation is conservatively excluded. + 6. Valid live identical observations still intersect correctly. +- **Regression Suite**: `tests/test_stale_process_intersection.py` (9 tests, all passing). + +--- + +### 3.2 Test-Order Contamination Fix + +- **Location**: `tests/test_scheduler_restart_doublefire.py::_setup_isolated_db` +- **Root Cause**: The test performed bare module attribute assignments (`cd.engine = eng`, `cd.SessionLocal = sessionmaker(...)`) to replace `core.database` objects with a minimal in-memory SQLite database containing only scheduler tables. Because bare assignments bypassed pytest's teardown mechanism, subsequent tests like `tests/test_tool_approvals.py::test_dispatcher_rejects_approved_document_action_without_target` queried the leaked engine and crashed with `sqlite3.OperationalError: no such table: documents`. +- **Implementation**: Changed `_setup_isolated_db` to accept `monkeypatch` and execute assignments via `monkeypatch.setattr`. +- **Verification**: Bidirectional test ordering (`scheduler -> approvals` and `approvals -> scheduler`) now passes cleanly. + +--- + +### 3.3 P2-A: Browser Cancellation / Daemon Cleanup + +- **Location**: `src/agent_tools/web_tools.py::shutdown_private_browser_sessions` +- **Root Cause**: When a browser operation was cancelled, `execute_browser` invoked `record.invalidate()`, setting `record.session = None`. In `shutdown_private_browser_sessions()`, cleanup was guarded by `if session is not None and session.observation.daemon.owned():`. This conflated the in-memory capability with daemon process existence, bypassing shutdown cleanup for cancelled sessions. +- **Implementation**: + ```python + from src.browser_identity import _REGISTRY + for record in tuple(_REGISTRY.values()): + if record.env and "AGENT_BROWSER_SOCKET_DIR" in record.env: + browser_lifecycle.force_cleanup(Path(record.env["AGENT_BROWSER_SOCKET_DIR"]), record.key, + method="shutdown", pid_alive=lambda pid: _process_is_alive(pid)) + record.invalidate() + _REGISTRY.clear() + ``` +- **Regression Test**: Added `test_shutdown_cleans_up_invalidated_registered_browser_session` to `tests/test_private_browser_tool.py`. + +--- + +### 3.4 P2-B: Subprocess Environment Inheritance Lockdown + +- **Location**: `src/tool_execution.py::_agent_subprocess_env` and `src/agent_tools/subprocess_tools.py::_owned_spec` +- **Audit Findings**: Confirmed reachability of full `os.environ` into native child processes via both synchronous model tools, background `#!bg` jobs, and `_owned_spec` fallbacks. +- **Implementation**: Defined `_SAFE_SUBPROCESS_VARS` covering essential execution requirements (PATH, locales, terminal, Python virtualenv/site-packages, Windows essentials) and `_SENSITIVE_PATTERN` to strip credential-indicating keys. Applied clean environment fallback across `_agent_subprocess_env` and `_owned_spec`. + +--- + +### 3.5 Remote Scheduled SSH Refusal + +- **Contract**: Raw scheduled remote SSH without an exact external backend binding must remain fail-closed with `"Remote scheduled workload requires an exact external backend binding."`. +- **Implementation**: Verified that line 890 of `src/builtin_actions.py` remains active and deterministic. Added `tests/test_scheduled_remote_ssh_refusal.py` proving explicit refusal. + +--- + +## 4.
