Add an automated quality gate that enforces TDD bug fix workflow rules
on pull requests. The gate parses PR descriptions for bug-closing
keywords (Closes/Fixes/Resolves #N, ISSUES CLOSED: #N), searches the
codebase for corresponding TDD tests tagged @tdd_bug_N, and verifies
that @tdd_expected_fail tags have been removed.
Key components:
- scripts/tdd_quality_gate.py: Main quality gate script with PR
description parsing, TDD test discovery, and tag removal verification.
All public functions validate arguments fail-fast and are statically
typed.
- noxfile.py: New tdd_quality_gate session that reads PR_DESCRIPTION
from the environment and runs the quality gate script.
- .forgejo/workflows/ci.yml: New tdd_quality_gate CI job that runs
only on pull_request events, passing the PR body as PR_DESCRIPTION.
- features/tdd_quality_gate.feature: 46 Behave scenarios covering PR
parsing, TDD test search, tag removal verification, full gate logic,
robot diff handling, edge cases, argument validation, bool guards,
co-located bug false-positive guard, and main() CLI entry point.
- features/steps/tdd_quality_gate_steps.py: Step definitions for all
Behave scenarios using temporary directories for isolation.
- robot/tdd_quality_gate.robot: 15 Robot Framework integration tests
exercising the gate end-to-end via a helper subprocess.
- robot/helper_tdd_quality_gate.py: Helper script for Robot tests with
sentinel-based sub-commands.
Review-round fixes applied:
- check_expected_fail_removed now uses _contains_tag_token for
word-boundary matching (avoids false positives on partial tag names)
- Diff expected-fail removal detection tracks flags at file level
instead of per-hunk (fixes false negatives when tags span hunks)
- parse_bug_refs filters out issue number zero
- Redundant double error reporting eliminated (file-level check
short-circuits the diff-level check)
- run_quality_gate returns (errors, bug_refs) tuple to avoid
redundant re-parsing in main()
- Regex compilation cached via functools.lru_cache
- Nox session no longer installs the full project (stdlib only)
- CI checkout uses fetch-depth: 0 for reliable merge-base resolution
Review-round 2 fixes applied:
- _diff_has_expected_fail_removal_for_bug now requires the removed
line to contain both the expected-fail tag and the specific bug tag
(fixes false positives when two bugs share the same test file)
- check_expected_fail_removed error messages use the correct tag
prefix per file type (@tdd_bug_N for .feature, tdd_bug_N for .robot)
- bool values rejected by bug-number validation guards in
find_tdd_tests, check_expected_fail_removed, and
_diff_has_expected_fail_removal_for_bug
- File-read error handling catches UnicodeDecodeError alongside OSError
(root-safe unreadable-file handling via invalid-UTF-8 test fixture)
- Temp directory cleanup added to after_scenario hook in environment.py
- 8 new Behave scenarios: bool type guards (2), co-located bug
false-positive regression (1), run_quality_gate argument validation
(3), and main() CLI entry point exit codes (2)
Review-round 3 fixes applied:
- Synthetic PR diff helper (_default_pr_diff_for_bug_refs) now
auto-detects .robot vs .feature file type from the temp search
tree and generates the matching diff format (fixes under-tested
robot-format diff code path in multi-bug integration scenarios)
- check_expected_fail_removed test step now filters files by bug
tag via find_tdd_tests before checking (matches production path
in run_quality_gate)
- after_scenario temp directory cleanup no longer sets
context.temp_dir = None (fixes cleanup conflict with
cli_init_yes_flag_steps.py cleanup functions that run after hooks)
- 2 new Behave scenarios: multi-line PR description parsing, and
non-string pr_diff type guard for run_quality_gate
ISSUES CLOSED: #629
Fix the integration test helper so that it can load scripts/run_behave_parallel.py
outside of nox sessions. The helper imports the runner module via importlib, which
triggers the top-level from behave_pass_suppress_formatter import
PassSuppressFormatter. When invoked from integration tests (or any non-nox
context), neither behave_pass_suppress_formatter nor the behave_parallel
package (created by noxfile.py for unit_tests) is on sys.path, causing a
ModuleNotFoundError and all 6 Robot tests to fail with exit code 1.
The fix adds scripts/ to sys.path before loading the runner module so that
from behave_pass_suppress_formatter import PassSuppressFormatter resolves
correctly. This mirrors the approach already used in noxfile.py's unit_tests
session for the behave-parallel package.
Also addresses review feedback:
- Removes one blank line from scripts/run_behave_parallel.py to bring it to
499 lines, satisfying the project's <500-line code style rule.
- Moves in-function behave imports (Configuration, StreamOpener) in
features/steps/behave_parallel_log_filtering_steps.py to the top-level
import block alongside the existing behave imports, complying with the
project's rule that all imports must be at the top of the file.
Refs: #10987
Implemented PassSuppressFormatter, a custom Behave formatter that buffers
per-scenario output and only flushes it to stdout when the scenario failed
or errored. Passing scenarios produce no output, keeping an all-passing
suite at ~5-10 lines (the _print_overall_summary block only).
Key design decisions:
- PassSuppressFormatter (in scripts/behave_pass_suppress_formatter.py)
inherits from behave's Formatter base class so it can be registered via
behave.formatter._registry.register_as(), which enforces issubclass(cls,
Formatter).
- _SUPPRESS_STATUSES = {'passed', 'skipped'} determines which terminal
statuses are silently discarded; all others (failed, undefined, etc.)
trigger a buffer flush so no failure is hidden.
- _make_runner() in run_behave_parallel.py registers the formatter and
sets it as the default format whenever config.format is None (no
explicit -f/--format flag). Coverage mode (BEHAVE_PARALLEL_COVERAGE=1)
bypasses the formatter and falls back to config.default_format so
slipcover can instrument a single process.
- The formatter lives in a separate file to keep both scripts under the
500-line limit. _install_behave_parallel() in noxfile.py copies both
files into the behave_parallel package. A try/except import handles
both the direct-script path (tests via importlib) and the installed-
package path (nox CI).
- Three new BDD scenarios in behave_parallel_log_filtering.feature cover:
(1) passing scenario -> no output, (2) failing scenario -> full output,
(3) mixed run -> only failing scenario visible. All 20 scenarios pass.
ISSUES CLOSED: #10987
- Unit tests tend to fail due inconsitent DB file.
- Create a fresh copy on a temporary location and the atomically swap it.
- To always provide a completely initialized and migrated DB.
The ActorRegistry.add() method rejected spec-compliant YAML that uses the
actors: map format with nested config: blocks because it only looked for
provider/model at the top level of the blob. Four changes fix this:
1. _extract_v2_actor() now handles both the spec-canonical actors: key and
the legacy agents: key, with actors: taking precedence. It also supports
the combined actor field format (e.g. "openai/gpt-4") from the spec.
2. _extract_v2_options() mirrors the same actors:/agents: support.
3. registry.add() now unconditionally calls _extract_v2_actor() so that
nested unsafe flags and graph descriptors are always captured — even
when top-level provider/model are present. This eliminates the
behavioural asymmetry with from_blob().
4. The unsafe confirmation gate now runs before the duplicate-actor check,
and the graph_descriptor resolution uses explicit is-not-None checks
to distinguish "not set" from "set to empty dict".
Review fixes (cycle 4):
- Added 9 new Behave scenarios: _extract_v2_options edge cases (empty map,
None, list, missing options key), _extract_v2_actor with unsafe=True,
add() with missing name field, top-level unsafe: true (rejection +
acceptance), and multi-actor unsafe limitation documentation.
- Added graph descriptor assertions to all _extract_v2_actor direct
scenarios that were missing them.
- Fixed unsafe field coercion to use explicit boolean check (is True or
== 1) instead of bool() to prevent truthy non-boolean values like
"no" from being treated as unsafe.
- Added legacy graph key fallback (blob.get("graph")) in add() for
consistency with from_blob().
- Fixed _StubActorService.upsert_actor to handle set_default parameter
and pass non-None config_blob to Actor.compute_hash().
- Updated stale CLI comment about registry.add() capabilities.
- Applied ruff format to step definitions.
Review fixes (cycle 5 — external review):
- T1/T2/T3: Added unsafe coercion edge-case tests for 1.0 (float→True),
2 (int>1→False), and 0 (int zero→False).
- T4/T5/T6: Added _extract_v2_options tests for non-dict first entry,
missing config block, and actors: preference over agents:.
- T7: Added integration test for top-level graph_descriptor key.
- T8: Added integration tests for top-level provider_type/model_id aliases.
- T9: Added integration tests for top-level unsafe string coercion ("yes"/"no").
- S1: effective_unsafe now includes unsafe/allow_unsafe params to match
from_blob() and spec rule.
- S2: CHANGELOG entry expanded with multi-actor rejection, options
preservation, and coercion fix.
- B1: Changed v2_options guard from truthiness to is-not-None check.
- P1: _extract_v2_options() now returns a shallow copy.
- P2: Nested options overwrite non-dict top-level options values.
- Q3: Fixed comment variable name (unsafe_raw → top_unsafe_raw).
- S3: Added spec-extension comment for provider_type/model_id aliases.
- S4/B3: Cached actors_raw in multi-actor guard; added cross-ref comment.
- Q5: Added TODO(#10832) to _StubActorService duplicate.
- Q6: Replaced misleading (M2) label with (unsafe coercion).
Review fixes (cycle 6 — agent review):
- MAJ-1: Removed allow_unsafe from effective_unsafe computation.
allow_unsafe is a permission flag, not an assertion; it should not
mark a non-unsafe actor as unsafe. Updated docstring to clarify
the semantic difference between unsafe and allow_unsafe.
- MIN-1: Changed provider/model alias resolution in _extract_v2_actor()
from or-based to is-not-None checks for consistency with
_resolve_actors_map() and add().
- MIN-2: Added test scenario for allow_unsafe=True on non-unsafe YAML.
- MIN-3: Added test scenarios for top-level unsafe: 1 (integer)
rejection without flag and acceptance with flag.
- MIN-4: Added test scenario for graph descriptor additional keys loop
(routes key propagation).
- MIN-5: Added test scenario for non-dict top-level options with nested
options.
- MIN-9: Applied ruff format to step file (removed unnecessary parens).
- NIT-1: Differentiated redundant scenario to test graph descriptor
agent key value instead of duplicating assertions.
- NIT-2: Added test scenario verifying config_blob source: "yaml" default.
- NIT-5: Changed _resolve_actors_map() return type to use
Literal["actors", "agents"] for stronger type safety.
Includes 78 Behave scenarios covering spec-compliant actors: map,
legacy agents: map, top-level fields, rejection of missing provider/model,
combined actor field edge cases, update=True path, schema_version and
compiled_metadata forwarding, actors-as-list edge case, empty actors dict
blocking agents fallback, malformed actor field parts, reverse precedence
for the combined actor field, _extract_v2_options edge cases, unsafe=True
detection, missing name rejection, top-level unsafe, multi-actor
rejection, unsafe coercion edge cases (1.0, 2, 0, "yes", "no"),
top-level graph_descriptor, provider_type/model_id aliases,
_extract_v2_options structural parity with _extract_v2_actor,
allow_unsafe on non-unsafe YAML, top-level unsafe: 1 (integer),

Move alembic configuration and migration files from repository root into the
Python package structure to ensure they are included in the wheel distribution.
This fix resolves the FileNotFoundError when running `agents init` in Docker
containers or any environment using the built wheel distribution.
Changes:
- Move alembic/ directory from repo root to
src/cleveragents/infrastructure/database/migrations/
- Move alembic.ini to the same new location and update script_location setting
- Update MigrationRunner._find_alembic_ini() to search from the new canonical
location within the package
- Update create_template_db.py to point to the new alembic.ini location
- Update documentation references to reflect new migration file locations
- Create __init__.py for migrations package
- The env.py file is imported when running tests that verify all modules can be
imported without errors. However, context.config is only available when alembic
is actually running migrations, not during normal module imports. This caused
an AttributeError when the test tried to import the migrations.env module.
- Fix by using getattr() with a default value to safely access context.config,
and guard all code that uses config with None checks. This allows the module
to be safely imported while still functioning correctly during migrations.
Testing:
- Verified MigrationRunner can locate alembic.ini in new location
- Tested agents init succeeds in creating project with database
- Template database creation works correctly
- All migration tests should pass without changes
Alembic files now follow standard Python packaging conventions, making them
automatically included in wheel distributions without special configuration.
ISSUES CLOSED: #4180
Detect btrfs and overlayfs filesystems and automatically fall back to sequential
mode to prevent deadlocks caused by SQLite WAL file locking and btrfs COW copy-up
locks when multiple forked workers try to access the same files simultaneously.
The fix adds a _is_btrfs_or_overlayfs() function that:
1. Attempts to detect the filesystem type using stat command
2. Falls back to reading /proc/mounts if stat fails
3. Returns True if the filesystem is btrfs or overlayfs
The sequential mode condition is updated to include this check, ensuring that
on affected filesystems, all features run in a single process instead of being
split across multiple forked workers.
ISSUES CLOSED: #9390
Adjusted test running and file-detection logic to stabilize unit tests in overlayfs environments and improve target feature handling.
- Modified scripts/run_behave_parallel.py to run sequentially when there are 2 or fewer feature files, avoiding fork deadlocks on overlayfs and reducing nox-based unit test timeouts for agent_skills_loader and skill_search features.
- Updated noxfile.py to correctly detect feature files in posargs, fixing the prior logic that appended the "features/" directory when specific feature files were provided. This ensures precise test selection and avoids unnecessary path expansion.
Rationale:
These changes address the root causes of flaky unit test timeouts by preventing problematic forking behavior with small feature sets and by ensuring nox respects explicitly provided feature file paths.
ISSUES CLOSED: #9374
In parallel mode, the behave runner previously replayed captured
stdout/stderr for every worker chunk, creating noisy output that
obscured failure diagnostics in CI and local runs.
Changes to scripts/run_behave_parallel.py:
- Added _chunk_has_failures() and _chunk_no_scenarios_ran() helpers
to evaluate individual chunk summaries for failure/error/crash
conditions.
- Updated the aggregation loop in main() to conditionally replay
captured stdout/stderr only for chunks whose summary indicates
failures, errors, or no scenarios ran (crash detection). Passing
chunks now suppress their output entirely.
- Added robust exception handling in _worker_run_features() so that
worker crashes produce a full traceback in stderr and return a crash
summary with features.errors = 1, enabling the parent to detect the
crash via _chunk_has_failures (and also _chunk_no_scenarios_ran,
since no scenarios reached a terminal state) and replay the
diagnostics.
- The conditional replay uses summary-based checks rather than the
raw runner.run() boolean, consistent with the existing exit-code
logic. This avoids spurious log replay for @tdd_expected_fail
scenarios whose runner.run() returns True even though the TDD
inversion handler has corrected the scenario status to passed.
- Existing summary merge, exit semantics, and the no-scenarios
safety net are fully preserved.
New Behave unit tests (17 scenarios) cover the chunk-level helpers,
the conditional aggregation loop, the pure no-scenarios-ran path,
stderr replay for non-crash failed chunks, and the worker crash path.
New Robot integration tests (6 test cases) verify the same behavior
end-to-end via the helper_behave_parallel_log_filtering.py script.
Also updated:
- CHANGELOG.md: add unreleased entry for this behavioral change.
- features/steps/behave_parallel_log_filtering_steps.py: use
contextlib.redirect_stdout/redirect_stderr instead of manual
sys.stdout assignment; register module in sys.modules; document
CWD requirement in _load_runner_module().
- robot/helper_behave_parallel_log_filtering.py: move import io to
top-level; remove redundant inline imports; use contextlib for
output capture; register module in sys.modules; document CWD
requirement.
Branch note: the canonical branch for this fix is
bugfix/m3-behave-parallel-failed-chunk-logs. The PR head branch
(bugfix/mX-behave-parallel-failed-chunk-logs) cannot be renamed via
the Forgejo API; both branches are kept in sync at the same SHA.

Added os.chmod(db_path, 0o664) after database creation to ensure the template
database has writable permissions. This prevents sqlite3.OperationalError: attempt
to write a readonly database when tests copy and modify the template during test
setup.
The template database is now created with rw-rw-r-- (664) permissions instead of
the default rw-r--r-- (644), allowing the test runner process to write to it.

## Summary
The `lint` and `integration_tests` CI jobs on `master` are currently failing. This PR fixes both:
1. **Lint (`nox -e lint`)** — 51 ruff violations in `scripts/validate_automation_tracking.py`:
- Sorted imports per isort convention
- Replaced deprecated `typing.List`/`Dict`/`Tuple`/`Optional` with builtin equivalents (`list`, `dict`, `tuple`)
- Removed unused `Optional` import and unused local variable `issues`
- Fixed trailing whitespace, blank-line whitespace, and 6 lines exceeding 88-char limit
- Replaced `dict.keys()` with `dict` in membership tests
- Added return type annotation to `main()`
2. **Integration tests (`nox -e integration_tests`)** — 1 failure in `robot/coverage_threshold.robot`:
- Removed `tdd_expected_fail`, `tdd_issue`, and `tdd_issue_4305` tags from the `Noxfile Contains Coverage Threshold Constant` test
- The bug this TDD tag tracked (issue #4305) is now fixed — `COVERAGE_THRESHOLD = 97` exists in `noxfile.py`
- The TDD expected-fail listener was inverting the passing result to a failure
### Local verification
- `nox -e lint` — All checks passed
- `nox -e integration_tests` — 1962 tests, 1962 passed, 0 failed, 0 skipped
### Files changed
| File | Change |
|------|--------|
| `scripts/validate_automation_tracking.py` | Fixed all 51 lint violations |
| `robot/coverage_threshold.robot` | Removed stale `tdd_expected_fail` tag |

- Add check_opencode_running() function to detect existing OpenCode server
- Skip server startup if OpenCode already running on target port
- Display prominent warning when connecting to existing server
- Only manage server lifecycle when script starts its own server
- Add OWN_SERVER flag to track server ownership
- Update cleanup logic to leave existing servers running
This enables multiple developers and automation scripts to safely
run in parallel without conflicting server management.
Fix all failing CI quality gates (lint, unit_tests, format) without
suppressing any quality enforcement.
Root causes and fixes:
1. Format: features/steps/plan_namespaced_name_tdd_steps.py had trailing
whitespace; fixed by running ruff format.
2. Unit tests - A2A JSON-RPC 2.0 migration (commit 9c6d6915) renamed
A2aRequest fields (operation→method, request_id→id, a2a_version→jsonrpc)
and A2aResponse fields (status+data→result, request_id→id) but did not
update all step files and feature files:
- a2a_jsonrpc_wire_format_steps.py: added use_step_matcher('re') and
reset to 'parse' at end to prevent parallel test interference
- a2a_facade_wiring_steps.py: updated operation= to method=, .status/.data
to .result
- a2a_facade_steps.py: updated request_id→id, a2a_version→jsonrpc,

to prevent global matcher state leaking to subsequent step files
The TLS handshake failure on git.dev.cleveragents.com was caused by the
hostname being absent from the certificate's Subject Alternative Names
(SANs), or by SNI virtual-host misconfiguration on the server side.
This commit delivers the repository-side remediation:
- scripts/check-tls-cert.py: New TLS certificate health-check script.
Connects to a hostname, verifies the certificate's SANs include the
target hostname, checks expiry, and reports errors/warnings. Accepts
an injectable SSLContext for unit testing without real network access.
Supports wildcard SAN matching and configurable expiry warning threshold.
- docs/development/ops-runbook.md: New ops runbook documenting the full
certificate renewal procedure (Let's Encrypt/certbot and manual CA),
SNI misconfiguration diagnosis steps, expiry monitoring with cron, and
recommended alert thresholds (30/14/7/0 days).
- features/tls_certificate_check.feature: 14 Behave scenarios tagged
@tdd_issue @tdd_issue_1543 covering: missing SAN detection, valid SAN
acceptance, expired certificate detection, expiry warning threshold,
TLS handshake errors, connection timeouts, connection refused, wildcard
SAN matching, and _hostname_matches_san unit tests.
- features/steps/tls_certificate_check_steps.py: Step definitions for
the above feature, using unittest.mock to inject SSL contexts and
socket connections so no real network calls are made.
- mkdocs.yml: Added Ops Runbook to the Development section navigation.
The actual server-side certificate renewal (adding git.dev.cleveragents.com
as a SAN and reloading the web server) must be performed by the server
administrator following the procedure in docs/development/ops-runbook.md.

Move the large embedded `_BEHAVE_PARALLEL_CLI_SOURCE` string constant out of
noxfile.py and into a standalone `scripts/run_behave_parallel.py` module.
The `_install_behave_parallel()` helper now reads the script from disk via
`Path(__file__).parent / 'scripts' / 'run_behave_parallel.py'` instead of
embedding the source as a raw string literal. This allows ruff to lint and
type-check the runner independently, and makes noxfile.py significantly
shorter and easier to read.
No functional changes: the installed `behave-parallel` entry point is
identical to the previous embedded version. Parallel and sequential modes,
coverage integration, and the multiprocessing fork model are all preserved.
Fixed two SIM105 lint violations in the extracted script (replaced
try/except/pass with contextlib.suppress).

Created scripts/create_template_db.py that builds a pre-migrated SQLite
template database using Base.metadata.create_all() + alembic stamp
(~5ms for 34 tables, vs ~0.5-3s x 25 Alembic migrations per scenario).
Nox unit_tests and coverage_report sessions generate the template before
test execution and propagate CLEVERAGENTS_TEMPLATE_DB env var to all
workers.
features/environment.py before_all() installs a monkey-patch on
MigrationRunner.init_or_upgrade that copies the template for fresh
scenario temp DBs, falling through to real migrations for :memory:,
existing files, and migration-runner unit tests.
Quick wins: sleep(0.5) -> sleep(0.05) in cli_streaming wait step;
removed redundant Background re-declaration in cli_streaming.feature
