refactor(test): adopt native pytest-testmon lifecycle

[Sinity]

Summary

Replace Polylogue's bespoke seed, shard, mutation-proof, and repair registries with one automatic native pytest-testmon lifecycle owned by plain devtools verify. Every managed native pytest lane now runs under a closed-world command and environment contract, including ordinary affected selection.

Problem

The prior harness exposed several repair commands and separate state registries while still allowing stale or incomplete dependency authority. Untraceable runtime-data changes could select zero tests, deleted or moved modules could leave stale graph inputs, inherited pytest controls could suppress test bodies or narrow collection, configured discovery could omit failing tests, and linked worktrees could reuse or replace another checkout's database. Historical verification receipts could also be mistaken for current release authority.

Classifying individual pytest options was not a stable security boundary. --setup-only, --collect-only, positional selectors, --ignore-glob, --last-failed, configured addopts, configured testpaths, discovery patterns, and ambient plugins all provided independent ways to change what a managed invocation executed.

Solution

• Make plain devtools verify create, validate, copy, repair, and replace native testmon state automatically. No operator or agent seed/repair command remains.
• Replace the old shard, seed, testmon-state, and mutation-proof machinery with one native two-lane correctness corpus and one typed verification record.
• Give affected, bootstrap, and full lanes one exact positive command contract: the explicit tests root, repository-owned file/class/function patterns, an empty recursion exclusion, empty configured addopts, and only explicitly owned pytest plugins.
• Remove PYTEST_ADDOPTS and PYTEST_PLUGINS from every managed native child and disable ambient plugin autoload. Record addopts neutralization, plugin neutralization, and closed-world collection for each lane; release authority depends on those recorded invariants.
• Validate the complete generated command instead of maintaining a pytest option deny-list. Added selectors, ignores, deselection controls, positional targets, or later overrides invalidate the managed-command receipt.
• Force complete selection for untraceable package, test-runtime, and packaging changes. Exclude the intentional performance benchmark tree from correctness graph requirements.
• Treat deleted and moved Python paths as bootstrap triggers, then require post-build graph edges only for executable paths that still exist. Ordinary imports are executable; TYPE_CHECKING-only imports remain declarations.
• Bind testmon SQLite access to one no-follow checkout-owned directory descriptor through preparation, both lanes, and final inspection. Reject symlinked parents, database files, and sidecars; serialize the complete lifecycle with a checkout-local lock.
• Keep the checkout mutation monitor active through final Git HEAD and worktree fingerprint sampling on normal, preflight-failure, runner-exception, and interrupt paths. Every exceptional finalization denies release authority.
• Pin the validated native plugin range to pytest-testmon>=2.2.0,<2.3.0 and assert the private schema contract used by the inspector.
• Preserve the refactor: remove self-attesting campaign bureaucracy #3950/refactor: remove declarative artifact graph #3974 deletion set during the final rebase. Retired campaign, catalog, Beads, and evidence modules were not restored.

Verification

• direnv exec . devtools workspace verify-worktree /realm/worktrees/polylogue-native-testmon --expect-branch feature/test/native-testmon-lifecycle: isolated linked worktree verified at exact head c7556c982384dac9948f142301769088d0eee2da.
• direnv exec . devtools test tests/unit/devtools/test_verify.py tests/unit/devtools/test_testmon_bootstrap.py: 227 passed in 34.63s. This covers exact command construction, all three native modes, typed release authority, finalization paths, lifecycle locking, Git-authority monitoring, schema compatibility, change classification, plugin declarations, and symlink refusal.
• direnv exec . devtools test tests/integration/devtools/test_native_testmon_lifecycle.py -k 'production_affected_verify_neutralizes_execution_suppressing_addopts or production_verify_fails_closed_on_dynamic_pytest_plugins or managed_native_launch_keeps_state_inode_bound_during_parent_replacement or managed_native_routes_reject_replaced_cache_parent or production_verify_all_owns_complete_test_root_over_configured_testpaths or production_verify_all_neutralizes_external_pytest_addopts': 14 passed, 17 deselected in 126.43s. Real nested devtools verify invocations prove affected failing bodies execute under inherited --collect-only and --setup-only; full lanes cannot be narrowed by positional selectors, ignore globs, last-failed state, configured addopts/testpaths/discovery, or ambient plugins; dynamic repository plugin declarations fail closed; and parent replacement cannot redirect managed SQLite state.
• direnv exec . devtools verify --quick: all 10 format, lint, strict mypy, render, layering, command, schema, and promotion-audit gates passed in 28.17s. The receipt records matching initial/final head c7556c982384dac9948f142301769088d0eee2da and matching worktree fingerprints.
• git merge-base --is-ancestor b0cee7b99c36a7f8eb94bf122782255f42072709 HEAD: success. The branch is rebased onto the requested stable master.
• All 27 review threads were classified against current code, answered with concrete evidence, and resolved. The final thread was an outdated operations-layer concern on a file byte-identical between exact base and head, so it was recorded as a potentially valid base issue but non-actionable for this verifier-scoped PR. Five independent adversarial review iterations were run. Each in-scope finding was fixed and covered; the loop reached its five-iteration cap after the fifth fixes, so this does not claim an unrun sixth clean iteration.

Acceptance criteria

Criterion	Disposition	Evidence
Fresh main checkouts and linked worktrees acquire usable testmon state automatically	Satisfied	Production lifecycle tests cover absent state, main-checkout build, linked-worktree copy/rebind, malformed cache recovery, and atomic replacement.
Runtime or packaging data changes cannot yield a green zero-selection run	Satisfied	Change classification forces the complete correctness corpus, including additions and deletions.
Deleted and moved modules cannot preserve stale release authority	Satisfied	Deleted paths trigger bootstrap while post-build requirements include only extant executable paths; real deletion and rename routes are covered.
Ambient or configured pytest controls cannot suppress bodies or narrow managed authority	Satisfied	All native lanes own the exact command, environment, plugins, discovery, and explicit tests root. Production regressions observe failing parallel and load-sensitive bodies.
Parallel and serial lanes use the same authority contract	Satisfied	Both commands come from one builder and every aggregate requires both lanes to attest neutralization and closed-world collection.
Testmon state replacement is checkout-owned and race-safe	Satisfied	Parent/file/sidecar validation, no-follow directory binding, lifecycle locking, and mid-run parent replacement tests cover the production route.
Historical or exceptional receipts cannot grant current release authority	Satisfied	Typed scope compatibility remains diagnostic; checkout drift, preparation failure, runner exceptions, and interrupts finalize with release authority denied.
Manual seed, shard, and repair bureaucracy is removed	Satisfied	Legacy commands, registries, mutation-proof modules, seed-recovery suite, and scale-fixture registry remain deleted after rebasing.

Remaining scope

polylogue-lvz6 still owns final release-authority convergence. This PR supplies the automatic test-selection and baseline substrate; it does not claim that the production archive is release-ready.

Stack resolution

The branch is rebased directly onto stable master b0cee7b99c36a7f8eb94bf122782255f42072709. No further retarget or intermediate restack is required.

Exact-head review follow-up

At 43fee85a2a47512e5da9efaebde7f38bc5aaed47, all four current review findings were fixed and covered.

• Release-baseline bootstrap and --all lanes now force the full Hypothesis profile, and native environment preparation receives that explicit profile identity.
• The lifecycle lock is opened through a no-follow cache directory descriptor and checked as the same checkout-owned regular inode before it is truncated or written.
• A transient tracked-file mutation observed during changed-path classification or native preparation now makes the final exact-head receipt ineligible, even if the file is restored before pytest begins.
• Merge-train help and pending-status guidance now require a release-baseline devtools verify --all receipt; a narrow selection is explicitly described as insufficient.

Review-fix verification

• direnv exec . devtools test tests/unit/devtools/test_verify.py::test_native_testmon_lifecycle_lock_refuses_symlink_without_touching_target tests/unit/devtools/test_verify.py::test_preparation_mutation_withholds_release_authority_after_restoration tests/unit/devtools/test_merge_boundary.py::test_train_status_requires_release_baseline_guidance tests/integration/devtools/test_native_testmon_lifecycle.py::test_release_native_runs_override_a_reduced_hypothesis_profile: 5 passed in 19.50s. The production regression invokes both automatic-bootstrap and --all routes with HYPOTHESIS_PROFILE=verify, while each fixture test asserts the full 100-example profile and the receipt grants release authority.
• direnv exec . devtools verify --quick: all 10 quick gates passed in 25.78s at the exact head above.

Removing narrow-terminal from VerificationScope leaves persisted ledgers unhandled and untested. Validation now rejects any recorded scope outside the current enum, and the deleted narrow-authorization tests were not replaced, so the regression is neither prevented nor detected.

Do not discard coalesced Git authority events

When a .git/index or ref transaction restores the startup bytes before watchfiles drains its event, _record_change compares equal to _git_authority_signatures and returns. Exact-head verification then accepts an interval that changed Git authority. The existing authority tests restore the file only after _changed becomes true. Preserve event-time evidence or fail closed on authority-file events, and add coverage for restoration before event delivery.

Inline comments:
In `@CONTRIBUTING.md`:
- Around line 307-317: Update the verification documentation paragraph so it
distinguishes valid native environments, where plain devtools verify uses
pytest-testmon affected selection, from bootstrap failures or missing valid
native environments, where it runs the complete correctness corpus. Keep
devtools verify --all documented as the explicit complete-corpus option and
ensure the behavior matches the contract in CLAUDE.md.

In `@devtools/testmon_bootstrap.py`:
- Around line 436-440: Wrap the read-only connection in the inspection flow
around _readonly_uri with contextlib.closing so it closes on block exit. Also
wrap both source and destination sqlite3.connect calls in the backup flow with
contextlib.closing, ensuring all handles and sidecar mappings are released
before os.fsync and os.replace; update devtools/testmon_bootstrap.py lines
436-440 and 568-581.
- Around line 403-408: Constrain the pytest-testmon dependency in pyproject.toml
to the tested version range, keeping version 2.2.0 supported and excluding
untested future schema changes. Add a compatibility test covering
_testmon_schema_version and the private testmon.db tables/columns used by the
bootstrap logic, asserting the expected DATA_VERSION and schema shape.

In `@devtools/verify_runs.py`:
- Around line 1093-1112: Extract the repeated resource-counter scan into a
module-level _counter_delta helper near _distribution, collecting valid integer
values once and returning their max-minus-min delta or 0 when empty. Replace the
duplicated max/min logic for tree_read_bytes_delta and tree_write_bytes_delta
with calls to this helper using their respective counter keys.
- Around line 1150-1190: Extract the shared canonical-plus-event outcome merge
logic from aggregate_pytest_statistics and _terminal_outcomes_by_node into one
helper that accepts canonical outcomes and event phase reports, preserving
canonical results while filling omitted nodes from phase collapse. Update both
callers to use this helper so step statistics and pytest_aggregate compute
identical per-node terminal outcomes, including partial canonical reports.
- Around line 1307-1311: Unify pytest_aggregate field semantics across
aggregate_native_testmon_run and _history_pytest_aggregate: in
devtools/verify_runs.py lines 1307-1311, count non_green only for nodes with
reported terminal outcomes; in lines 1150-1190, extract and reuse one
terminal-outcome rule from both _terminal_outcomes_by_node and
aggregate_pytest_statistics, including partial-canonical-report merging; in
lines 183-202, emit None for corpus.digest when no nodeid list exists instead of
pairing a nonzero corpus.count with an empty-string digest.

In `@TESTING.md`:
- Around line 59-64: Update the documentation statement describing the native
environment key to specify that it includes only the repository-root conftest.py
and conftest.py files under tests/, matching _environment_input_paths in
devtools/testmon_bootstrap.py; do not claim that every conftest.py is included.

In `@tests/benchmarks/test_scale_tiers.py`:
- Around line 1-6: The scale-tier benchmark tests currently neither enable
pytest-benchmark nor record measured samples. Update the benchmark runner
configuration to pass --benchmark-enable for the nightly command, and wrap the
measured calls in the scale-tier probe tests with the benchmark fixture so
nightly-results.json receives samples.

In `@tests/integration/devtools/test_native_testmon_lifecycle.py`:
- Around line 28-31: Update the module-level pytest timeout marker to exceed the
maximum combined duration of the nested subprocess waits in the affected
lifecycle tests, including _run_plain_verify_corpus, _run_production_verify, and
the interrupted-bootstrap readiness and communication waits; preserve the
existing inner timeout budgets.
- Around line 133-135: Update _run_lane to handle a missing selection.json after
subprocess.run: include the completed process’s captured stdout and stderr in
the raised failure so pytest collection or usage errors remain visible, while
preserving normal selection payload parsing when the file exists.
- Around line 583-588: Update the process lifecycle around the started-file
assertion so it does not call process.communicate in the assertion message;
terminate the child with SIGINT first, then call communicate to collect its
output and use that output when reporting a failed started.exists() check,
ensuring the child is always cleaned up.

In `@tests/unit/devtools/test_merge_boundary.py`:
- Around line 232-247: The merge-boundary tests need coverage for persisted
verification scopes that are no longer valid enum members. Add one case
verifying a ledger with last_full_verify.verification_scope set to
"narrow-terminal" remains readable and cmd_train_status reports the train as
incomplete, plus another verifying _pending_prs_since_last_full_verify does not
grant release-baseline authority from a receipt whose scope is not
"release-baseline".

In `@tests/unit/infra/test_archive_templates.py`:
- Around line 49-54: Update the test around clone_archive_template to reopen the
original template with ArchiveStore(template) after cloning, while retaining the
existing marker and clone checks, so the source template’s usability is
explicitly verified.
- Around line 39-46: Update test_clone_rebinds_durable_bootstrap_identity to
isolate the archive root used by ArchiveStore’s writable-identity preflight:
apply the existing workspace_env fixture or patch polylogue.paths.archive_root()
to the test’s temporary workspace before constructing ArchiveStore(template),
while preserving the test’s clone assertions.

In `@tests/unit/storage/test_perf_rescue_1314.py`:
- Around line 77-81: Isolate mutations to the session-scoped bench_db_1k in
test_search_session_hits_uses_freshness_ledger_before_match and the related
tests: use a per-test copy of index.db, or reliably restore the original
freshness-ledger row after each test, so the shared database state and READY 1/1
record cannot leak between tests.

Review current code only. Audit every managed native pytest route, including affected, bootstrap, full, parallel, serial, preflight failure, runner exception, and interrupt finalization. Look for any ambient or configured pytest option, plugin, discovery setting, positional selector, state-path replacement, checkout mutation, or record-construction path that could suppress test bodies, narrow the owned tests corpus, or grant release authority without complete current evidence. Check the rebase integration between packed-ref filtering and Git-authority content signatures, and confirm the #3950/#3974 deletion set was not resurrected. Treat comments and historical heads as context rather than authority. Leave inline P0/P1/P2 findings only when current production behavior supports them; otherwise report that no legitimate gaps remain.

json.loads call to handle invalid completed.stdout and report both captured
stdout and stderr in the failure output. Ensure JSON parsing failures do not
discard the subprocess diagnostics, while preserving the existing receipt and
allow_rejection handling.
- Around line 84-90: Update _pytest_environment and _run_lane to neutralize
inherited pytest configuration for plain lanes: clear ambient PYTEST_ADDOPTS and
PYTEST_PLUGINS, pass the pytest option disabling addopts, and disable plugin
autoload to match the production path. Preserve the ability for tests to provide
intentional values explicitly through the env mapping.

@coderabbitai review

Please review exact head 9d3120c94d59a0c30d7e3ea58e22aaea2bbe8fc1. This update addresses the four current review threads: deadline-bounded plugin discovery, preserved Git-authority mutation baselines, plain-lane pytest isolation, and JSON failure diagnostics.

[coderabbitai]

@Sinity: I will review commit 9d3120c94d59a0c30d7e3ea58e22aaea2bbe8fc1 with focus on the four listed fixes.

@coderabbitai review

Exact-head review requested for 0aec21d. This update rejects hard-linked lifecycle locks and native testmon database sidecars, bounds lock acquisition, removes checkout-controlled PYTHONPATH from managed children, excludes ignored benchmark conftests from the environment digest, and keeps untraceable packaging Python inputs out of graph-edge requirements.

Focused verification: direnv exec . devtools test for 14 production regressions passed. direnv exec . devtools verify --quick passed locally and again in the pre-push hook. The requested affected route was exercised but bootstrapped a 20,368-node corpus and exposed unrelated failures in untouched core/archive tests; it was interrupted after 459 seconds, and its failed receipt is retained.

Please review this exact head only.

[coderabbitai]

@Sinity: I will review exact head 0aec21d533852de32320c5ffc380e85ff017a18b only. I will focus on the listed native testmon lifecycle and verification evidence changes.

Reject dangling database symlinks.

Path.exists() returns False for a dangling symlink. This path returns absent before lstat() can reject it. A dangling -wal already follows the fail-closed path through is_symlink().

Check data_path.is_symlink() in the absence condition. Add a regression test for a dangling primary database symlink.

Proposed fix

-    if not data_path.exists():
+    if not data_path.exists() and not data_path.is_symlink():
