Summary
Aligned the
agents actor runcommand signature with the specification by introducing positionalNAMEandPROMPTarguments. The spec defines:Previously the command used
--config/-cand--prompt/-poptions, which meant the spec's documented examples could not be typed verbatim on the CLI.Changes

feature/m4-actor-run-signature(commit6f05be2c) plus close connections to surrounding code.Reference: Issue #901, specification
docs/specification.mdlines 273–278 and 4560–4616.Method: 3 full review cycles across all problem categories (bugs, error handling, security, performance, test coverage, test flaws, spec compliance, conventions) until no new findings emerged.
Summary
The PR correctly aligns the
actor runCLI signature with the specification by introducing positionalNAMEandPROMPTarguments, making--config/-coptional, and adding registry-based actor resolution. The spec compliance is accurate. However, 4 high-severity issues and 5 medium-severity issues were found, primarily around error handling, resource management, and test coverage gaps.Finding count: 4 High, 5 Medium, 4 Low
P1 — HIGH (Must Fix)
P1-1: Bare
except Exceptionmasks infrastructure errorsFiles:
actor.py:60,actor_run.py:37actor_registry.get(name)raisesNotFoundError(ResourceNotFoundError) when an actor is not found (seeactor_service.py:72). The current code catches all exceptions:This swallows
DatabaseError,OperationalError,TypeError,AttributeError, and any other exception — all producing the misleading message "Actor 'X' not found in registry". A database connectivity failure would be silently misreported as "not found".actor.pyalready importsNotFoundErrorat line 20 but does not use it here.CONTRIBUTING.md §Exception Propagation (lines 496–504): "Do not use bare catch-all exception handlers without re-raising unless you have specific recovery logic."
Fix: Catch
NotFoundErrorspecifically. Let other exceptions propagate to the existingexcept CleverAgentsError/except Exceptionhandlers inrun():P1-2: Container/registry initialization errors produce raw traceback
Files:
actor.py:55–56(outsidetry),actor_run.py:32–33(outsidetry)get_container()andcontainer.actor_registry()are called outside thetry/exceptblock inside_resolve_config_files. Furthermore,_resolve_config_filesitself is called outside thetryblock inrun()(actor.py:162,actor_run.py:139):If the database is not initialized, or the DI container is misconfigured,
get_container()oractor_registry()will raise an unhandled exception producing a raw traceback instead of a user-friendly error message.Fix: Either move the
_resolve_config_files(...)call inside the existingtryblock inrun(), or wrap the container initialization calls within_resolve_config_files's own try/except with a clear error message (e.g., "Failed to initialize actor registry. Runagents initfirst.").P1-3: Temporary files never cleaned up (resource leak)
Files:
actor.py:75–80,actor_run.py:53–58delete=Falsecreates a file that persists indefinitely. There is no cleanup mechanism — noatexit.register, nofinallyblock, no context manager in the caller. Over time, repeated CLI invocations accumulate orphaned.yamlfiles in the system temp directory.Fix: Register cleanup, e.g.:
Or add cleanup in a
finallyblock in therun()function afterReactiveCleverAgentsApphas consumed the file.P1-4: Missing CHANGELOG.md entry
CONTRIBUTING.md §Pull Request Process (line 265): "The PR must include an update to the changelog file."
The diff contains no changes to
CHANGELOG.md. Other merged PRs on master consistently include changelog entries (see PRs #971, #973, #1050, #1051, #1052, #811).Fix: Add an entry under
## Unreleaseddescribing the CLI signature change.P2 — MEDIUM (Should Fix)
P2-1:
_resolve_config_filesduplicated between two filesFiles:
actor.py:42–80,actor_run.py:16–58The function is duplicated verbatim (38 lines of identical logic) across both files. The only difference is that
actor_run.pylazily importsget_containerwhileactor.pyuses the pre-existing module-level import.Review Playbook classifies "minor code duplication" as P2 (Medium — should-fix).
Fix: Extract to a shared utility (e.g.,
cleveragents.cli.commands._resolve_utils). This also resolves P3-2 (inconsistent imports) and partially addresses P3-3 (actor.py line count).P2-2: No guard for
config_blobbeingNoneFiles:
actor.py:67–71,actor_run.py:44–49If the actor has neither
yaml_textnor a validconfig_blob(i.e.,config_blobisNone),yaml.dump(None)produces'null\n'— an invalid YAML configuration that will causeReactiveCleverAgentsAppto fail with a confusing downstream error.Fix: Guard against
None:P2-3: No test exercises the real
_resolve_config_filesregistry pathFiles:
actor_run_signature_steps.py,helper_actor_run_signature.pyAll BDD and Robot tests for registry-based resolution mock
_resolve_config_filesentirely:The actual function logic — registry lookup, yaml_text extraction, temp file creation — is never tested. Bugs in the real registry call, YAML serialization, or temp file creation would go undetected.
Fix: Add at least one integration-level test that exercises the real
_resolve_config_fileswith a mockedactor_registry(injected via the DI container), not the entire function.P2-4: No test for the
yaml_text→config_blobfallback branchFiles:
actor.py:68–71,actor_run.py:45–49The
if not yaml_text:branch that falls back toyaml.dump(actor.config_blob)is untested. This code path would execute when an actor is registered viaactor addwith a config that doesn't preserve raw YAML text.Fix: Add a scenario where the mocked actor has
yaml_text=None(or"") but a validconfig_blob, verifying the serialization fallback works correctly.P2-5: Missing
@coveragetags on new BDD scenariosFile:
actor_run_signature.featureAll 7 new scenarios lack tags. The project has 193+ feature files using
@coveragetags as a convention for scenarios that exist primarily to increase code coverage.Fix: Add appropriate tags, e.g.:
P3 — LOW (Nice to Have)
P3-1: Robot tests missing
timeoutandon_timeout=killFile:
actor_run_signature.robotThree
Run Processcalls have notimeoutoron_timeout=kill:The project-wide convention (used in the majority of
.robotfiles) istimeout=120s on_timeout=kill. The CHANGELOG (line 374) explicitly references adding timeouts as a fix. Note:skill_actor_run.robotalso lacks these, so the pattern is pre-existing in one peer file.P3-2: Inconsistent import style between
actor.pyandactor_run.pyactor.pyimportsget_containerat module level (line 15, pre-existing).actor_run.pyimports it lazily inside_resolve_config_fileswith a comment: "Lazy import to avoid circular dependency at module level." Additionally,yamlandtempfileare lazily imported in both files without documented circular dependency justification. This inconsistency resolves naturally if P2-1 (extraction) is implemented.P3-3:
actor.pyline count continues to grow (739 lines)CONTRIBUTING.md §Modular Design (line 399): "Keep files under 500 lines."
The file was 679 lines on master, now 739 (+60 for
_resolve_config_files+ new positional arg declarations). This is a pre-existing issue (acknowledged in PR #971) but worsened by this PR. Resolving P2-1 (extraction to a shared module) would reclaim ~40 lines.P3-4: Test mock functions duplicate production error message text
Files:
actor_run_signature_steps.py:29–32,helper_actor_run_signature.py:122–125The
_not_found_resolvetest helpers hardcode the exact production error message. If the production message changes, the mocks will produce stale output. The assertion ("not found in registry" in combined) is substring-based and somewhat resilient, but the mock-to-production coupling adds maintenance burden.Spec Compliance

6c913f93Summary
The PR correctly introduces positional
NAMEandPROMPTarguments toagents actor run, aligning the CLI with the specification. The shared_resolve_actor.pymodule eliminates duplication betweenactor.pyandactor_run.py. Backward compatibility via--configis preserved. The CHANGELOG entry is thorough.After three full review cycles across all categories (bugs, security, performance, test coverage, test flaws, code quality), 9 findings were identified. None are critical blockers, but 3 are medium-severity items worth addressing before merge.
Findings by Severity
P2 — Medium Severity (3 findings)
actor_run.pyactor_run.pycatchesCleverAgentsExceptionwhileactor.pycatchesCleverAgentsError. The new_resolve_config_filescall introduces registry/container access (get_container(),container.actor_registry()) that can raiseInfrastructureError,DatabaseError, etc. These inherit fromCleverAgentsError, not fromCleverAgentsException, so inactor_run.pythey fall through to the genericexcept Exceptionhandler producing a less user-friendly"Unexpected error: ..."message with exit code 3 instead of the expected"Error: ..."with exit code 2. The root asymmetry is pre-existing, but this PR adds a new code path that is more likely to trigger infrastructure errors than the old config-file-only path. Suggested fix: changeactor_run.py:162fromexcept CleverAgentsExceptiontoexcept CleverAgentsError, matchingactor.py:189._resolve_actor.pyyaml.dumpused instead ofyaml.safe_dump. The codebase predominantly usesyaml.safe_dump(5 occurrences:materializers.py,repl.py,actor/schema.py,persona/registry.py) vsyaml.dump(3 occurrences).yaml.safe_dumprefuses to serialize arbitrary Python objects and only emits standard YAML types. Ifconfig_blobever contained unexpected types (e.g., datetime, Pydantic model),yaml.dumpwould silently produce Python-specific YAML tags (!!python/object:), whileyaml.safe_dumpwould raiseRepresenterError— failing fast per ADR-005 principles. Suggested fix: replaceyaml.dump(config_blob, default_flow_style=False)withyaml.safe_dump(config_blob, default_flow_style=False)._resolve_actor.py_resolve_config_files. The docstring documents that "Other exceptions fromget_container()orcontainer.actor_registry()are not caught here so callers can handle infrastructure failures in their owntryblocks." No test verifies this contract. Combined with P2-1, an infrastructure error inactor_run.pywould produce wrong behavior (exit code 3 instead of 2). Suggested fix: add a BDD scenario whereget_container()raisesInfrastructureErrorand verify it propagates to the caller.P3 — Low Severity (6 findings)

TheActormodel definesconfig_blobwithdefault_factory=dict, so newly created actors haveconfig_blob = {}.

Suggested fix: add a Robot test case (or helper function) exercising registry resolution viaactor_app.actor_run_signature_steps.pynamebeing empty string. Edge case:agents actor run "" "my prompt"would reachactor_registry.get("")with unpredictable behavior. A defensive test would validate the error path.

If the real message changes, these mocks won't catch the drift. This is partially mitigated by theresolve_config_filesunit tests that exercise the real function. Suggested fix: extract the error message to a constant in_resolve_actor.pyand reference it from test mocks, or rely solely on the unit tests for message validation and use a looser match in integration tests._resolve_actor.pygetattron known Pydantic model fields.getattr(actor, "yaml_text", None)andgetattr(actor, "config_blob", None)are used, butyaml_textandconfig_blobare declared fields on theActorPydantic model (with defaultsNoneanddict()respectively). Direct access (actor.yaml_text,actor.config_blob) would be cleaner, provide better type-checker coverage, and would surface model changes at type-check time instead of silently defaulting. Suggested fix: replace withactor.yaml_textandactor.config_blob.Not Flagged (Verified Correct)

The PR correctly implements the core requirement: aligning
agents actor runwith the specification's positional<NAME> <PROMPT>arguments, extracting shared resolution logic into_resolve_actor.py, and preserving--config/-cas an optional backward-compatibility fallback. Two rounds of review fixes are well-integrated. However, one critical issue was found that blocks merge: 48 invocations across 9 Robot test files still use the removed-pflag and will break on merge.Findings by Severity
P1 — Critical (Blocks Merge)
actor runinvocations still use the removed-pflag. The PR removes--prompt/-pfrom bothactor.pyandactor_run.py, but onlyrxpy_route_validation.robotandhelper_skill_actor_run.pywere updated. The following Robot files still pass-pas the prompt option and will fail with"Error: No such option: -p"after merge.Affected files and counts:

-p <PROMPT>to the new positional<NAME> <PROMPT>pattern (matching what was done forrxpy_route_validation.robot). Since these Robot tests invoke the CLI via subprocess (python -m cleveragents actor run), they exercise the real argument parsing and will fail immediately.P2 — Medium (Should Fix)
actor.py,actor_run.py--config/-cis not in the specification foractor run. The spec (lines 4562-4566) lists no--configoption. While issue #901 AC explicitly accepts keeping it as optional, the deviation is not documented. This codebase uses formalSD-Nnumbered deviation registries (seecli/output/__init__.pywith 29 entries). A spec deviation note should be added — either in_resolve_actor.pymodule docstring oractor.py— to prevent future contributors from treating this as an oversight.actor.py,actor_run.py--configsays "fallback" but the option takes precedence.help="YAML config paths (fallback: load from file instead of registry)"— the parenthetical implies--configis used when registry lookup fails.

Summary
The PR correctly aligns the
agents actor runcommand signature with the specification by introducing positionalNAMEandPROMPTarguments, extracting shared resolution logic to_resolve_actor.py, updating 9 Robot test files, and adding comprehensive BDD + Robot tests. The implementation is solid overall. The findings below are organized by severity.Findings
P2 — Medium Severity
_resolve_actor.py:73yaml.safe_dumpfailure on non-serializableconfig_blob. Ifconfig_blobcontains types thatyaml.safe_dumpcannot serialize (e.g., custom objects,set,datetime), ayaml.RepresenterErrorpropagates uncaught throughresolve_config_files. This bypasses the user-friendlytyper.echoerror path and could surface as a raw traceback to the user. Theexcept CleverAgentsErrorin the caller would NOT catch it (sinceRepresenterErroris not aCleverAgentsError). Suggested fix: Either wrapyaml.safe_dump()in atry/except yaml.YAMLErrorthat emits a user-friendly message and raisestyper.Exit(code=2), or add a BDD scenario confirming the error propagates to the genericexcept Exceptionhandler in the caller.features/steps/actor_run_signature_steps.py:318import yamlin step definition. The commit message states "P3-8: Moved 5 inline imports to module level per CONTRIBUTING.md §1292-1294", but thisimport yamlinsidestep_temp_file_from_config_blobwas left inline. This is inconsistent with the stated convention. Suggested fix: Moveimport yamlto the module level with the other imports.robot/helper_actor_run_signature.py:75,112,149assertwithout descriptive message in Robot helper. Three assertions (assert "config response" in result.output,assert "registry response" in result.output,assert "actor-app registry response" in result.output) produce a bareAssertionErroron failure without diagnostic context. The Robot Framework log would show onlyAssertionErrorwith no indication of what was expected vs. actual. Other assertions in the same file use theif/print(stderr)/sys.exit(1)pattern which gives much better diagnostics. Suggested fix: Add descriptive messages:assert "config response" in result.output, f"Expected 'config response' in output, got: {result.output}", or convert to theif/print/sys.exitpattern used elsewhere in the file.P3 — Low Severity
_resolve_actor.py:81atexithandler accumulation. Each call toresolve_config_filesregisters a newatexithandler viaatexit.register(lambda ...). If the function is called multiple times in the same process (unlikely for CLI, possible in test suites that exercise the real function), handlers accumulate in theatexitcallback list. Impact: Negligible for CLI usage. For test scenarios,context.add_cleanup()is already used in the BDD steps, so theatexithandlers are redundant in that context. No action required — noting for awareness._resolve_actor.py:81atexitcleanup removes temp files. The temp file cleanup relies onatexit, which only runs at interpreter exit. There is no BDD or Robot test that verifies the temp file is actually deleted after the process ends. This is inherently difficult to test in-process. Impact: Low — temp files are small, in the OS temp directory, and cleaned up on reboot.--help) could surface unexpected behavior. Impact: Low — Typer's argument parser is well-tested and--can be used to separate flags from positional args._resolve_actor.py:64.strip()onyaml_text. TheActorPydantic model hasstr_strip_whitespace=Truein itsConfigDict(actor.py:79), soactor.yaml_textis already stripped by Pydantic before it reaches this code. The explicit.strip()is a no-op. Impact: None — belt-and-suspenders approach is harmless. Noting for documentation clarity.Observations (Informational, No Action Required)
CleverAgentsExceptiontoCleverAgentsErroris verified correct. PR #971 hadactor_run.pyusingexcept CleverAgentsException(narrower). This PR changes both files toexcept CleverAgentsError(the root base class). Verified via exception hierarchy:CleverAgentsExceptioninherits fromCleverAgentsError. The broadening is necessary becauseInfrastructureError(which can be raised byget_container()during registry resolution) inherits directly fromCleverAgentsError, NOT fromCleverAgentsException. Without this change, infrastructure errors from the new registry resolution path would fall through to the genericexcept Exceptionhandler instead of getting a user-friendly message. The change is intentional, well-reasoned, and correctly documented in the commit message (round 2 P2-1).--config/-cspec deviation is properly documented. The spec (§277) definesactor runwith NO--configoption. The implementation preserves--configas an optional convenience, documented in_resolve_actor.py:7-14with references to spec lines 4562-4566 and issue #901 AC.--configis provided. Users who previously usedagents actor run -c config.yaml -p "prompt"must now provide a NAME:agents actor run -c config.yaml any-name "prompt". The NAME is ignored when--configis present, but Typer still requires it. This is correct per spec (NAME is always required). The CHANGELOG documents this breaking change.run()function is still duplicated betweenactor.pyandactor_run.py. This was noted as a pre-existing known limitation in PR #971. The new_resolve_actor.pyextraction reduces duplication for the resolution logic. Full deduplication of the_execute()closure is deferred.Positive Aspects

Scope: Code changes in branch
feature/m4-actor-run-signaturevsmaster(commit8342e296) plus close connections to surrounding code.References: Issue #901, Specification §4560-4579 (
agents actor run),docs/specification.mdline 277.Methodology: 4 full review cycles across all categories (bugs, security, performance, test coverage, code quality).
Summary
The implementation is solid. The
actor runcommand signature is correctly aligned with the specification's<NAME> <PROMPT>positional arguments. The shared_resolve_actor.pymodule is well-structured, exception handling is properly ordered, the spec deviation for--configis clearly documented, and the 48 migrated Robot test invocations are consistent. All 17 new BDD scenarios and 4 Robot tests exercise the core paths.8 findings identified across 4 review cycles. None are critical. 4 are medium (P3), 4 are low (P4).
P3 — Medium Severity
P3-1 [Test Coverage] No BDD scenario for whitespace-only
yaml_textLocation:
_resolve_actor.py:64, missing inactor_run_signature.featureThe
.strip()guard (documented in commit round 3 as fix P3-1) handles whitespace-onlyyaml_textcorrectly (e.g.," \n "→ stripped to""→ falls through toconfig_blob), but there is no BDD scenario specifically exercising this path. Current tests only use the empty string"".Risk: A regression removing
.strip()would not cause any test failure.Suggested fix: Add a scenario like:
with
mock_actor.yaml_text = " \n "andmock_actor.config_blob = {"name": "ws-actor", "type": "custom"}.P3-2 [Test Coverage] Config-precedence tests don't verify registry was NOT consulted
Location:
actor_run_signature_steps.py:111-132(actor_app),actor_run_signature_steps.py:156-176(actor_run_app)The "Config flag takes precedence" scenarios verify
exit_code == 0and thatrun_single_shotwas called, but they do not assert thatactor_registry.get()was never invoked. The tests pass because the real_resolve_config_filesreturns early when config is non-empty, but a spy on the registry would make the precedence assertion explicit and guard against future regressions.Risk: If someone accidentally changes
_resolve_config_filesto always consult the registry (even when--configis provided), these tests would still pass.Suggested fix: In the config-precedence tests, wrap with an additional mock on
_resolve_actor.get_containerand assertactor_registry.get.assert_not_called()after invocation. Alternatively, patch_resolve_config_fileswith a spy that records whether the registry path was taken.P3-3 [Test Coverage] No test for multiple
--configfiles combined with positional NAMELocation: Missing in
actor_run_signature.featureThe
configparameter islist[Path] | Nonesupporting repeated--config, but no test exercises providing two or more config files alongside the positional NAME argument (e.g.,--config a.yaml --config b.yaml my-actor "prompt"). The_resolve_config_filesfunction returns the config list as-is when non-empty (regardless of length), but the Typer argument parsing interaction with multiple options + positional args deserves explicit coverage.Suggested fix: Add a scenario that invokes with
["run", "--config", path_a, "--config", path_b, "my-actor", "prompt"]and asserts both config files are passed toReactiveCleverAgentsApp.P3-4 [Resource Management]
atexithandlers accumulate per call in same-process usageLocation:
_resolve_actor.py:89Each invocation of
resolve_config_files(without--config) registers a newatexithandler. In CLI usage (one process per command invocation) this is harmless — at most 1 handler per process. However, in test suites running multiple scenarios viaCliRunnerin the same Python process,atexithandlers accumulate without bound. Each is a trivial lambda, but theatexit._exithandlerslist grows with every call.Suggested fix: Track temp paths in a module-level set and register a single
atexithandler that iterates and cleans all paths:Then in
resolve_config_files:_temp_files.add(tmp.name)instead of registering a new handler each time.P4 — Low Severity
P4-1 [Test Coverage] Error message content not verified in exit-code-only tests
Location:
actor_run_signature_steps.py:355-357,383-385,498-500The "no-configuration-data", "not-found", and "serialisation error" BDD scenarios only assert
exit_code == 2without checking the actual error message substring (e.g.,"has no configuration data","not found in registry","could not be serialised"). If the message text becomes incorrect or misleading, the tests would not detect it.Suggested fix: Add
assert "no configuration data" in combined(or equivalent) alongside the exit code check, similar to howstep_actor_run_registry_not_foundalready checks"not found in registry" in combined.P4-2 [Test Coverage] No Robot test for
actor_appunknown-name error pathLocation:
actor_run_signature.robotRobot tests cover the
actor_run_apperror path ("Unknown Actor Name Error") and theactor_apphappy path ("Actor App Registry Resolution"), but there is no Robot test for theactor_apperror path (unknown name → exit code 2 viaactor_app). BDD does cover this path via the "Error when actor name not found in registry" scenario.Suggested fix: Add a Robot test case "Actor App Unknown Name Error" using the helper with a new sub-command that exercises the
actor_apperror path.P4-3 [Test Maintainability]
_not_found_resolvemock duplicates production error message formatLocation:
actor_run_signature_steps.py:33-39,helper_actor_run_signature.py:174-179Both the BDD steps and Robot helper define a
_not_found_resolvemock that hardcodes the same error message format as_resolve_actor.py:58-61. If the production message changes, these mocks would silently diverge while tests still pass (assertions use substring matching on the mock's message, not the production code's actual output).Suggested fix: Consider importing a constant or helper from
_resolve_actor.pyfor the error message format, or restructure the mock to delegate to the real function with a mocked registry that raisesNotFoundError.P4-4 [Security] User-controlled actor name interpolated in error messages without sanitization
Location:
_resolve_actor.py:58-61,68-71,76-79The
nameparameter (user-controlled CLI input) is interpolated directly intotyper.echo()without sanitization. Ifnamecontains ANSI escape codes or terminal control sequences, they would render in the user's terminal. The risk is low for local CLI usage (the user controls their own input) but should be considered if error messages are ever logged to shared contexts (server mode, web dashboards, CI logs).Suggested fix: Apply
strip_terminal_escapes()(or equivalent) tonamebefore interpolation, or note this as a known limitation for local-only CLI usage.Findings Not Raised (Verified Correct)

Verdict: Request Changes
The implementation is solid from a spec compliance and correctness perspective — all ticket acceptance criteria are satisfied, the CLI signature matches the specification, and the production code is well-structured after 5 prior review rounds. However, two major quality issues must be addressed before merge: a new test file that significantly exceeds the 500-line limit and an excessively verbose CHANGELOG entry. Additionally, the PR has merge conflicts with

The PR is currently not mergeable due to conflicts with
master(noted by @freemo in comments on Day 42 and Day 43). This must be resolved via rebase before any merge can happen.Summary
The core implementation is strong: the CLI signature correctly matches the specification, shared
_resolve_actor.pycleanly eliminates code duplication for the resolution logic, exception handling is properly ordered and narrowed, all 48+ Robot test migrations are complete, and 22 BDD + 5 Robot test scenarios provide solid coverage. All prior review round issues have been addressed.The remaining issues are primarily about project standards compliance (file length, CHANGELOG format, commit email) and test robustness improvements. After resolving the two major items and the merge conflicts, this PR should be ready for approval.

Merge conflict with
master— The PR is currently not mergeable (noted by @freemo on Day 42 and Day 43). A rebase is required before merge. This is an operational concern, not a code quality issue.Summary
This PR is the result of 6 thorough review rounds, and it shows. The core implementation is strong: the CLI signature correctly matches the specification, the shared
_resolve_actor.pymodule cleanly eliminates code duplication for actor resolution logic, exception handling is properly ordered and narrowed,yaml.safe_dumpprevents YAML injection, input sanitization protects error messages from terminal control sequences, temp file management usesatexitwith proper tracking, and all 56+ Robot test migrations and 25 BDD test updates are complete and consistent. The 23 BDD scenarios and 5 Robot integration tests provide comprehensive coverage including edge cases (whitespace yaml_text, empty config_blob, YAML serialization failure, infrastructure error propagation, cleanup verification). All prior review issues from 5 rounds have been addressed.The remaining findings are all minor (test hardening, pre-existing file size, defensive improvements) or nits. None affect runtime correctness or spec compliance. The PR is ready to merge after resolving the merge conflict with
master.Review: APPROVED
