From 91ce1c2047dd11f4ccbb34dfb2e7cb4df49b7bed Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Wed, 13 May 2026 09:34:14 +0300 Subject: [PATCH] [AZ-326] [AZ-327] C12 operator-tool CLI + companion SSH bringup AZ-326 (3pt): operator-tool Click CLI shell at src/gps_denied_onboard/components/c12_operator_tooling/cli.py with six subcommands (download, build-cache, upload-pending, reloc-confirm, verify-ready, set-sector); SectorClassificationStore (atomic-write JSON under ~/.azaion/onboard/sector-classifications.json); freshness-table lookup driving AC-NEW-6; EXIT_* constants; AZ-266 structured-JSON log wiring to a rotating ~/.azaion/onboard/c12-tooling.log handler; operator-tool console-script entry in pyproject.toml. AZ-327 (3pt): CompanionBringup orchestrator at src/gps_denied_onboard/components/c12_operator_tooling/companion_bringup.py that opens an SSH session against the companion (paramiko per project pin), checks the four pre-flight artifacts (Manifest, expected engines, sha256 sidecars, calibration), and returns a ReadinessReport per description.md S2; CompanionUnreachableError + ContentHashMismatchError with operator-friendly remediation hints; ParamikoSshSessionFactory + RemoteSidecarVerifier (sha256sum + cat over SSH, no bytes pulled to the workstation); paramiko>=3.4,<4.0 dep added. NFR-perf-cold-start fix: PEP 562 lazy __getattr__ in c12_operator_tooling/__init__.py and flights_api/__init__.py defers HttpxFlightsApiClient (httpx), ParamikoSshSession[Factory] (paramiko + cryptography), bbox_from_waypoints / takeoff_origin_from_flight (numpy + pyproj). cli.py imports from leaf flights_api modules. operator-tool --help cold start: ~870ms -> <200ms typical, <500ms p99. Includes 73 unit tests (incl. paramiko-version-drift smoke per AZ-327 Risk 1) + console-script integration test. All 1494 repo-wide unit tests pass; 80 skips are pre-existing environment gates.

It wires + the AZ-266 structured JSON logger to a rotating workstation-side log + file. +- AZ-327 ships `CompanionBringup` — SSH-driven pre-flight verification of + the companion's four artifacts (`Manifest.json`, expected `.engine` + files, AZ-280 `.sha256` sidecars, calibration JSON), the + `RemoteSidecarVerifier` that invokes `sha256sum` over SSH (no engine + bytes pulled back to the workstation), and the two error families + (`CompanionUnreachableError`, `ContentHashMismatchError`). + +This unblocks AZ-328 (cache-build orchestrator), AZ-329 (post-landing +upload trigger), AZ-330 (operator reloc service), and gives operators the +first end-to-end CLI surface for the C12 epic. + +## Architectural Decisions + +### 1. Click instead of Typer + +The AZ-326 task spec calls for Typer; the project pin is `click>=8.1` and +the spec's own Constraints section forbids new dependencies. Click was +chosen, preserving the user-facing surface (subcommand names, `--help` +text, exit codes, log lines) and only swapping the framework. Documented +in `cli.py`'s module docstring. + +### 2. Module placement under `components/c12_operator_tooling/` + +The AZ-326 spec suggested a top-level `src/operator_tool/` package, but +`_docs/02_document/module-layout.md` (the authoritative ownership file) +places C12 under `src/gps_denied_onboard/components/c12_operator_tooling/`, +matching the AZ-489 `FlightsApiClient` placement that already shipped. +Module-layout was treated as authoritative; the spec drift has been +recorded as a doc-only issue (no remediation task — the spec is the only +file out of sync). + +### 3. PEP 562 lazy re-exports for heavy adapters + +The AZ-326 NFR-perf-cold-start (≤500 ms p99 for `operator-tool --help`) +forbids eager-importing `paramiko`, `httpx`, or `pymavlink` at CLI +load time. Implementation: + +- `c12_operator_tooling/__init__.py` and + `flights_api/__init__.py` use a PEP 562 `__getattr__` hook to lazily + load `HttpxFlightsApiClient`, `ParamikoSshSession[Factory]`, + `bbox_from_waypoints`, and `takeoff_origin_from_flight`. Type-checking + imports are gated on `if TYPE_CHECKING:` so mypy / IDE behaviour is + unchanged. +- `cli.py` imports flights-api types directly from the leaf modules + (`flights_api.errors`, `flights_api.interface`) instead of via the + package `__init__.py`, bypassing even the lazy machinery in the hot + path. + +Effect: cold-start dropped from ≈870 ms to <200 ms typical, <500 ms p99 +on a developer laptop. `python -X importtime` confirms zero `paramiko`, +`httpx`, `cryptography`, `pyproj`, `cv2`, or `gtsam` imports at CLI +module load time. + +### 4. CLI test injection via dict `ctx.obj` + +The CLI's app callback recognises pre-populated `ctx.obj` dicts of the +form `{"config": C12Config, "logger": Logger, "services": ...}` and +preserves them. This lets unit tests inject fake service collaborators +without monkey-patching Click internals. The injection point is +documented in the app callback's docstring. + +### 5. Logger refresh on log-path change + +`_ensure_cli_logger` was originally a "first call wins" idempotent helper. +That blocked test isolation (each test writes to a different temp log +path) and would silently misbehave for any in-process operator use of +multiple `--log-path` overrides. Reworked to detect when the configured +log-path changes and to swap CLI-owned handlers atomically — same +behaviour for the common single-call path, correct behaviour for +override and test scenarios. + +## Files Changed + +### Production source (new) + +- `src/gps_denied_onboard/components/c12_operator_tooling/_types.py` — + shared DTOs and enums (`SectorClassification`, `CompanionAddress`, + `ReadinessReport`, `ReadinessOutcome`, `CompanionUnreachableReason`, + `AreaIdentifier`). +- `src/gps_denied_onboard/components/c12_operator_tooling/exit_codes.py` + — `EXIT_*` constants per AZ-326 §Outcome. +- `src/gps_denied_onboard/components/c12_operator_tooling/freshness_table.py` + — `FRESHNESS_TABLE` + `freshness_threshold_months(...)` (AC-NEW-6). +- `src/gps_denied_onboard/components/c12_operator_tooling/config.py` — + `C12Config`, `C12CompanionConfig`, `HostKeyPolicy`. +- `src/gps_denied_onboard/components/c12_operator_tooling/errors.py` — + `CompanionUnreachableError`, `ContentHashMismatchError`, both with + `remediation` properties. +- `src/gps_denied_onboard/components/c12_operator_tooling/ssh_session.py` + — `SshSession` / `SshSessionFactory` Protocols + `RemoteCommandResult`. +- `src/gps_denied_onboard/components/c12_operator_tooling/paramiko_ssh_session.py` + — concrete `paramiko.SSHClient`-backed implementation. +- `src/gps_denied_onboard/components/c12_operator_tooling/remote_sidecar_verifier.py` + — remote `sha256sum` + sidecar `cat` comparator. +- `src/gps_denied_onboard/components/c12_operator_tooling/companion_bringup.py` + — `CompanionBringup` orchestrator. +- `src/gps_denied_onboard/components/c12_operator_tooling/sector_classification_store.py` + — atomic-write JSON store (already shipped as part of preceding work). +- `src/gps_denied_onboard/components/c12_operator_tooling/cli.py` — Click + app + six subcommands + `main()` entry point. +- `src/gps_denied_onboard/components/c12_operator_tooling/__main__.py` — + module-entry shim. + +### Production source (modified) + +- `src/gps_denied_onboard/components/c12_operator_tooling/__init__.py` — + PEP 562 lazy re-exports + `register_component_block("c12_operator_tooling", C12Config)`. +- `src/gps_denied_onboard/components/c12_operator_tooling/flights_api/__init__.py` + — PEP 562 lazy re-exports for `HttpxFlightsApiClient`, `bbox_from_waypoints`, + `takeoff_origin_from_flight`. +- `src/gps_denied_onboard/runtime_root/c12_factory.py` — added + `build_sector_classification_store`, `build_companion_bringup`, + expanded `build_operator_tool` to aggregate the three services into + `OperatorToolServices`. +- `pyproject.toml` — added `paramiko>=3.4,<4.0` dependency and the + `operator-tool = "...c12_operator_tooling.cli:main"` console script + entry. + +### Tests (new) + +- `tests/unit/c12_operator_tooling/test_freshness_table.py` +- `tests/unit/c12_operator_tooling/test_exit_codes.py` +- `tests/unit/c12_operator_tooling/test_sector_classification_store.py` +- `tests/unit/c12_operator_tooling/test_cli_help_and_logging.py` +- `tests/unit/c12_operator_tooling/test_cli_build_cache.py` +- `tests/unit/c12_operator_tooling/test_cli_console_script.py` +- `tests/unit/c12_operator_tooling/test_companion_bringup.py` +- `tests/unit/c12_operator_tooling/test_paramiko_factory_smoke.py` — + Risk-1 mitigation (paramiko version-drift catch). + +## Task Results + +| Task | Status | Files Modified | Tests | AC Coverage | Issues | +|------|--------|---------------|-------|-------------|--------| +| AZ-326_c12_cli_app | Done | 12 prod + 6 tests | 73 unit + 1 integration pass | 17/17 ACs + NFR-perf-cold-start | 1 minor (see below) | +| AZ-327_c12_companion_bringup | Done | 7 prod + 2 tests | 18 unit pass | 10/10 ACs + NFR-perf-cold-call | None | + +## AC Test Coverage: All covered + +Every acceptance criterion from both task specs has a directly-validating +test (verified inline before code review). + +## Code Review Verdict: PASS_WITH_WARNINGS + +### Findings + +- **Low / Style**: `cli.py:_ensure_cli_logger` swallows `Exception` from + `handler.close()` during the log-path swap.
