Closes #87 (follow-on: the documented gate is referenced by source but ABSENT; conftest stubs the a2a+claude SDKs so nothing real runs; credential_helper runs every boot untested).

Problem

Issue #87 calls out a documented-but-absent test gate:

test_boot_routes.py is referenced in molecule_runtime/boot_routes.py as the contract for the build_routes pure function. The function was extracted precisely so the contract could be unit-tested without the heavy a2a-sdk / claude_agent_sdk imports — but the test file was never authored. The main.py consumer was # pragma: no cover and the only coverage was end-to-end via the responsiveness-e2e job, which is too slow for the fast unit lane.
credential_helper (the 2026-06-08 "MiniMax cred incident" — lost 39 workspaces because the helper was only mocked) was tested only via test_credential_helper_determinism.py with mocked subprocess calls. Real subprocess calls to git config, nohup, gh auth login were never exercised in CI.

Fix

Two new test files, no production code change:

tests/test_boot_routes.py (6 tests, 4-branch card/JSON-RPC contract + real-executor smoke).
tests/test_credential_helper_subprocess.py (5 tests, real subprocess).

The 4-branch contract:

Branch A — executor is not None → DefaultRequestHandler + InMemoryTaskStore.
Branch B — executor is None, adapter_error is None → not_configured_handler (generic).
Branch C — executor is None, adapter_error is set → not_configured_handler with the operator hint (the 2026-06-15 family of incidents; the operator MUST see the failure reason in canvas, not a generic "agent not configured" message).
Branch D — falsy inputs → card route still mounted (defensive guard).
Boot ordering — card route MUST be first in the returned list (Starlette resolves in order; a future re-coupling would silently bypass the PR #2756 decoupling).
Real-executor smoke — build_routes with a real a2a-sdk AgentCard + a real DefaultRequestHandler. Loudly skipped if a2a-sdk is not installed; the unit-tests lane in CI has it via pip install -e ..

The credential_helper subprocess contract:

_extract_scripts() writes real bash scripts + executable bit.
_configure_git_credential_helper() runs real git config and the result is readable back via git config --global --get (the !-prefixed shell-command convention is asserted).
_start_refresh_daemon() spawns a real nohup'd process and writes a parseable PID file.
install_credential_helper() under gitea: full no-op (the "do not install GitHub machinery" contract — regression class for the 2026-06-08 incident).
install_credential_helper() under github + token-shaped value: all three artifacts (scripts, git config, PID file) produced; the token-shaped value does NOT leak into the log output.

Test plan

New tests/test_boot_routes.py: 6 tests, all pass locally.
New tests/test_credential_helper_subprocess.py: 5 tests, all pass locally.
Full unit suite: 664 passed, 1 skipped, 0 regressions. (Integration e2e is run separately by CI's responsiveness-e2e job.)

SOP checklist

Comprehensive testing performed: Full unit suite (pytest --ignore=tests/integration) — 664 passed, 1 skipped. The new tests cover both the unit-level build_routes contract and the real-subprocess credential_helper wire that previously was only mocked. No production code changed.
Local-postgres E2E run: N/A — pure test files; no DB or runtime dep changes.
Staging-smoke verified or pending: Pending — the pip install -e . step in CI's unit-tests and responsiveness-e2e jobs already pulls the real a2a-sdk; the new test_build_routes_real_executor_smoke test will exercise the real wire on every CI run.
Root-cause not symptom: Adds the test gate that was supposed to be authored when build_routes was extracted in PR #2756. Without this gate, a future re-coupling refactor would silently bypass the decoupling and the "stuck-booting-forever" UX would re-ship. For credential_helper, the test exercises the real subprocess (the part that was mocked and missed the 2026-06-08 incident).
Five-Axis review walked: correctness / robustness / security / performance / readability. The credential_helper test asserts the token-shaped value does NOT leak into logs (security); the build_routes test asserts the card route is always first in the routes list (correctness); the 4-branch coverage is exhaustive (robustness).
No backwards-compat shim / dead code added: No shim. Test files only.
Memory consulted: feedback_no_single_source_of_truth (the test file is the SSOT for the build_routes contract), feedback_no_such_thing_as_flakes (the credential_helper subprocess test pins the wire against non-determinism — if a future refactor introduces a real regression, the test fails LOUDLY).

What this commit pins
--------------------

tests/test_boot_routes.py (6 tests, 4-branch card/JSON-RPC contract):

  - Branch A: executor present -> DefaultRequestHandler + InMemoryTaskStore
  - Branch B: executor None, no adapter_error -> not_configured_handler
  - Branch C: executor None, adapter_error set -> not_configured_handler
    (the 2026-06-15 family contract; the operator hint reaches canvas
    instead of a generic 'agent not configured' message)
  - Branch D: falsy inputs -> card route still mounted (defensive guard)
  - Boot-ordering: card route MUST be first in the returned list
    (Starlette resolves in order; a future refactor that re-couples
    the two would silently break the PR #2756 decoupling)
  - Real-executor smoke: build_routes with a REAL a2a-sdk AgentCard
    + a real DefaultRequestHandler (no mocks). Skipped LOUDLY if
    a2a-sdk is not installed; the unit-tests lane in CI has it via
    `pip install -e .` and exercises this smoke.

tests/test_credential_helper_subprocess.py (5 tests, real subprocess):

  - _extract_scripts() writes real bash scripts to
    $HOME/.molecule-runtime/scripts/ + executable bit
  - _configure_git_credential_helper() runs real `git config` and
    the result is readable back via `git config --global --get`
    (the !-prefixed shell-command convention is asserted)
  - _start_refresh_daemon() spawns a real nohup'd process and writes
    a parseable PID file
  - install_credential_helper() under gitea: full no-op (the
    'do not install GitHub machinery' contract — regression class
    for the 2026-06-08 MiniMax cred incident)
  - install_credential_helper() under github + token-shaped value:
    all three artifacts (scripts, git config, PID file) produced;
    the token-shaped value does NOT leak into the log output

The credential_helper tests retarget the module's _INSTALL_DIR and
_TOKEN_CACHE_DIR at the test's temp HOME (direct attribute
assignment, NOT importlib.reload — the latter breaks import
machinery for the parent package's other imports).

Why this is the 'real-executor smoke' the issue calls for
--------------------------------------------------------

The unit-tests job in .gitea/workflows/ci.yml already runs the test
suite after `pip install -e .` (which pulls the real a2a-sdk). The
new test_build_routes_real_executor_smoke is the integration gate for
build_routes against the real a2a types, and the
test_credential_helper_subprocess.* tests are the real-subprocess
contract for the credential helper that previously was only mocked.
The responsiveness-e2e job continues to cover the real uvicorn wire
end-to-end.

No production code changed — test files only.

APPROVED: 5-axis review complete. Correctness: tests-only change adds real coverage for the documented boot-route contract and credential-helper subprocess side effects; no production behavior changes. Robustness: covers card route presence/order, executor/not-configured branches, adapter-error path, git config side effects, daemon PID artifact, and provider no-op behavior with temp HOME isolation. Security: no secrets added; subprocess tests use token-shaped fixtures only and secret-scan is green. Performance: tests are bounded and use temp dirs/subprocess smoke rather than long-running integration flows. Readability: long but well-scoped regression tests with clear incident context. CI is green.

5-axis review: APPROVED at head a1c0045a.

Test-only PR. test_boot_routes.py pins the boot-route contract, including always-mounted agent-card route, JSON-RPC route behavior, route ordering, and a real Starlette/TestClient smoke. test_credential_helper_subprocess.py exercises real subprocess/git-config side effects under temp HOME rather than only mocked behavior. No production behavior/security/performance change; CI reported green and PR is mergeable.
