Add four CLI-based integration test cases to the M5 E2E verification suite
that exercise the exact commands from the v3.4.0 milestone description via
real subprocess calls to `python -m cleveragents`.
CLI test cases:
- CLI Project Create Large Project: `agents project create local/large-project`
- CLI Resource Add Git Checkout: `agents resource add git-checkout ...`
- CLI Project Link Resource: `agents project link-resource ...`
- CLI Project Show Displays Linked Resource: `agents project show ...`
Each test creates an isolated temp directory with its own CLEVERAGENTS_HOME,
initialises a workspace via `agents init`, runs the target CLI command as a
subprocess with `on_timeout=kill`, asserts zero exit code and verifies
expected output, then tears down the temp directory.
Bug fix: ProjectResourceLinkRepository.create_link() and remove_link() only
called session.flush() without session.commit(), causing linked resource data
to be silently lost between sessions. Added session.commit() to both methods,
plus finally: session.close() to match the session-factory lifecycle pattern
used by all other mutating repository methods. Added session.refresh() and
session.expunge() before return in create_link() so the returned ORM instance
is fully loaded and usable in detached state after session close.
Regression guard: Added two cross-session persistence Behave scenarios
(project_repository.feature) that open a new session from the same engine
after create_link/remove_link and verify the operation was durably committed.
Test improvements from review feedback (rounds 1 and 2):
- Per-test CLEVERAGENTS_HOME isolation via env: override on all Run Process
calls to prevent shared state between tests.
- Stronger ULID-based assertions: CLI tests capture the resource_id ULID from
resource show output and verify the exact ID in project show output.
- Regex-based branch assertion (branch.*main) instead of generic string match.
- Test 4 differentiated from Test 3 by verifying resource show independently
after linking and asserting the specific resource ULID.
- Documentation noting context tier and ACMS criteria are validated at the
Python API level via helper_m5_e2e_verification.py.
- Updated ProjectResourceLinkRepository class docstring documenting commit
and close behaviour of mutating methods.
- CHANGELOG entry for both test additions and production bug fix.
- Redundant Library imports removed, --format plain on project list, comments
explaining fake repo directories, standardised Run Process line style.
Context/ACMS CLI coverage is intentionally not added because the CLI does not
yet expose dedicated context/ACMS inspection commands. These criteria are
validated at the Python API level via helper_m5_e2e_verification.py.
