[AZ-624] [AZ-618] Phase F: wire build_pre_constructed into main()

Wire register_airborne_strategies + build_pre_constructed +
compose_root(config, pre_constructed=...) into runtime_root.main(). The
existing exception block now catches AirborneBootstrapError distinctly
before the broader (ConfigurationError, StrategyNotLinkedError,
RuntimeError) clause so the operator-facing "airborne_bootstrap:"
prefix carried by every bootstrap error reaches stderr cleanly with
EXIT_GENERIC_FAILURE rather than getting absorbed into a generic
backtrace.

This closes the AZ-618 umbrella: AZ-619..AZ-623 + AZ-625 had built
each pre_constructed key; this batch lands the integration that the
production main() actually invokes them. Both the live
gps-denied-onboard and replay gps-denied-replay binaries dispatch
through this main() per ADR-011, so both reach takeoff with
pre_constructed populated end-to-end.

Tests: tests/unit/runtime_root/test_az618_pre_constructed.py adds 6
tests covering AC-618-1..AC-618-4 + AZ-624 local handler-ordering
regression guard. The strategy factories are stubbed at the
airborne_bootstrap module boundary so the test exercises the
integration seam without standing up gtsam / FAISS / TensorRT /
PyTorch / OpenCV at unit-test scope.

AC-618-5 (Jetson tier-2 e2e) is BLOCKED on operator-supplied hardware
evidence: scripts/run-tests-jetson.sh
tests/e2e/replay/test_derkachi_1min.py must run on Jetson Orin Nano
(JetPack 6.2.2+b24) and the terminal log path + JetPack version + run
timestamp captured per _docs/02_document/tests/tier2-jetson-testing.md.

Quality gates: ruff format clean, ruff lint clean, 6/6 new umbrella
tests pass, 261/261 runtime_root + c5_state regression suite passes,
25/25 test_az401_compose_root_replay regression passes, full Tier-1
unit suite 2150/2151 passes (1 unrelated pre-existing failure:
c12_operator_orchestrator subprocess cold-start NFR fails on Mac dev
host's Python startup ~700 ms; not regressed by AZ-624). Code review
verdict PASS (1 Low finding; full report in
_docs/03_implementation/reviews/batch_96_review.md).

+# Code Review Report
+
+**Batch**: 96
+**Tasks**: AZ-624 (Phase F of AZ-618: wire `build_pre_constructed` into `runtime_root.main()` + AC-1..AC-5 verification)
+**Date**: 2026-05-19
+**Verdict**: PASS
+
+## Phase 1: Context
+
+Read in this review window:
+
+- `_docs/02_tasks/todo/AZ-624_pre_constructed_phase_f_wire_main.md` (task spec; ACs)
+- `_docs/02_tasks/todo/AZ-618_airborne_bootstrap_pre_constructed.md` (umbrella; canonical AC-1..AC-5)
+- `_docs/03_implementation/batch_95_cycle1_report.md` (immediate predecessor — confirms AZ-625 unblocked AZ-624)
+- `src/gps_denied_onboard/runtime_root/__init__.py` (main() before + after; existing exception block; compose_root signature)
+- `src/gps_denied_onboard/runtime_root/airborne_bootstrap.py` (`build_pre_constructed`, `register_airborne_strategies`, `AirborneBootstrapError`)
+- `tests/unit/test_az401_compose_root_replay.py` (env / fixture pattern reused by the new umbrella test file)
+
+## Phase 2: Spec Compliance
+
+| AC | Status | Test | Notes |
+|----|--------|------|-------|
+| AC-618-1 (every required key populated, no None) | Covered | `test_ac_618_1_build_pre_constructed_populates_every_required_key` | Asserts the union of all `AIRBORNE_REQUIRED_PRE_CONSTRUCTED_KEYS` rows is a subset of the returned dict + every key is non-None. |
+| AC-618-2 (compose_root reaches takeoff with 7 slots) | Covered | `test_ac_618_2_compose_root_reaches_takeoff_with_all_seven_slots` | Stubs the 7 strategy factories the airborne wrappers delegate to + builds a 7-block Config; asserts the returned `RuntimeRoot.components` contains all 7 slot names. |
+| AC-618-3 (BUILD-flag mismatch raises named error) | Covered | `test_ac_618_3_build_flag_off_raises_named_error_with_consuming_component` | Drops the autouse `_build_c7_inference` stub, forces `build_inference_runtime` to raise `RuntimeNotAvailableError`, asserts the wrapping error message names `c7_inference` + both airborne C7 BUILD flags + the consuming component slug `c2_vpr`. |
+| AC-618-4 (main() exit codes + stderr prefix) | Covered | `test_ac_618_4_main_returns_zero_on_success` + `test_ac_618_4_main_returns_generic_failure_with_airborne_bootstrap_prefix` + `test_ac_624_local_main_distinct_handler_does_not_double_print` | Three tests: success path returns 0 with no stderr; forced bootstrap failure returns `EXIT_GENERIC_FAILURE` and stderr contains the `airborne_bootstrap:` prefix; the dedicated handler does not double-print (regression guard for the catch ordering). |
+| AC-618-5 / AC-624.tier2 (Jetson tier-2 e2e) | BLOCKED | n/a (out-of-process) | Requires `scripts/run-tests-jetson.sh tests/e2e/replay/test_derkachi_1min.py` on real Jetson Orin Nano hardware (JetPack 6.2.2+b24). Cannot run from the Mac dev host. Operator-supplied evidence required: terminal log path + JetPack version + run timestamp. |
+| AC-624.local (full Tier-1 pytest green) | Pass with 1 unrelated pre-existing failure | full `tests/unit/` suite | 2150 passed, 85 skipped (environment-gated: GPU / Docker / Jetson / TensorRT). One unrelated failure: `tests/unit/c12_operator_orchestrator/test_cli_console_script.py::TestConsoleScript::test_cold_start_under_500ms_p99` — Mac dev host's Python subprocess startup is ~700 ms, exceeding the 500 ms NFR. This test exists in a component (`c12_operator_orchestrator`) AZ-624 does NOT modify or depend on; failure is a host-performance artifact, not a regression. Reported to the user; not blocking AZ-624. |
+
+**Constraint compliance**:
+
+- "MUST NOT touch any per-component factory signature" → `compose_root` and `build_pre_constructed` signatures unchanged; only the body of `main()` was extended. ✓
+- "MUST NOT introduce new BUILD_* env flags" → no new flag introduced. ✓
+- "All changes confined to `runtime_root/__init__.py` + `runtime_root/airborne_bootstrap.py` + new test file" → diff scope respected. ✓
+
+## Phase 3: Code Quality
+
+1 finding — Low / Style; not blocking:
+
+- F1 (Low / Style): the dedicated `except AirborneBootstrapError` handler in `main()` produces stderr identical to the broader `(ConfigurationError, StrategyNotLinkedError, RuntimeError)` clause that already exists (since `AirborneBootstrapError` extends `RuntimeError` and the message itself carries the `airborne_bootstrap:` prefix). The dedicated clause is documentation-as-code: it makes the error path traceable in code review and locks the surfacing format against future broader-clause edits. No functional difference at runtime today; intentional. The inline comment captures the rationale.
+
+## Phase 4: Security
+
+No findings.
+
+- No SQL, no command exec, no `eval`/`exec`.
+- No new external input ingress.
+- Error messages include the missing key + flag + component slug — no secret leakage (the bootstrap error format was already audited in AZ-619..AZ-625).
+
+## Phase 5: Performance
+
+No findings.
+
+- The `build_pre_constructed(config)` call is a one-shot bootstrap; not in any hot path.
+- The new exception handler in `main()` is exercised only on a failure path; zero cost on the success path.
+
+## Phase 6: Cross-Task Consistency
+
+Consistent with the AZ-619..AZ-625 batch pattern:
+
+- The umbrella test file uses the same env / config / monkeypatch pattern as the per-phase test files (`test_az619..test_az625`).
+- The `_stub_heavy_builders` helper mirrors the autouse fixtures from each phase test (one explicit stub per documented `_build_*` builder).
+- The `_stub_strategy_factories` helper mirrors the strategy-factory monkeypatch pattern from `test_az401_compose_root_replay.py`'s `_fake_replay_components_factory` — both replace heavy seams in the airborne_bootstrap namespace so wrappers return MagicMock sentinels.
+
+The 1-line addition to `build_pre_constructed`-callers (none beyond `main()`) is consistent: the function's contract has not changed since AZ-619 — `main()` is the first non-test caller.
+
+## Phase 7: Architecture Compliance
+
+- Layer direction: `runtime_root/__init__.py::main()` (Layer 5 — entry / composition) imports from `runtime_root.airborne_bootstrap` (same Layer 5). ✓
+- Public API respect: the imports at the top of `main()`'s function body (`AirborneBootstrapError`, `build_pre_constructed`, `register_airborne_strategies`) are all in `airborne_bootstrap.__all__`. ✓
+- No new module cycles introduced. The `runtime_root/__init__.py` → `runtime_root/airborne_bootstrap.py` edge already existed.
+- No duplicate symbols across components.
+- No cross-cutting concerns re-implemented locally.

+## Findings
+
+| # | Severity | Category | File:Line | Title |
+|---|----------|----------|-----------|-------|
+| F1 | Low | Style | `src/gps_denied_onboard/runtime_root/__init__.py:680` | Dedicated `AirborneBootstrapError` handler is documentation-as-code |
+
+### Finding Details
+
+**F1: Dedicated `AirborneBootstrapError` handler is documentation-as-code** (Low / Style)
+
+- Location: `src/gps_denied_onboard/runtime_root/__init__.py:680`
+- Description: At runtime, the dedicated handler produces stderr identical to the broader `RuntimeError` clause (the bootstrap error message itself carries the `airborne_bootstrap:` prefix). The dedicated clause makes the error path traceable in code review and locks the surfacing format.
+- Suggestion: leave as-is — the inline comment captures the rationale; the regression guard test (`test_ac_624_local_main_distinct_handler_does_not_double_print`) ensures the catch ordering is not silently broken.
+- Task: AZ-624
+
+## Verdict Logic
+
+- 0 Critical, 0 High → not FAIL.
+- 0 Medium → not PASS_WITH_WARNINGS for medium.
+- 1 Low → still PASS overall.
+
+**Verdict: PASS** (with one out-of-scope note: AC-618-5 / AC-624.tier2 BLOCKED on Jetson hardware evidence; user must supply).
