Summary
Implements the full Fix-then-Revalidate orchestration loop that runs when a required validation fails during the Execute phase. This includes: failure diagnosis, self-fix attempt by the execution actor, re-validation, retry limiting, strategy revision escalation, and terminal failure handling.

Code Review Report: Fix-then-Revalidate Orchestration Loop
PR: #711 | Issue: #583 | Branch:
feature/m6-fix-then-revalidate-loopCommit:
639680a9by Luis MendesReviewed against:
docs/specification.md(lines ~22310-22528, ~28240-28462, ~45698-45701) and Issue #583 acceptance criteria.Review methodology: 4 iterative global cycles covering all categories (bugs, spec compliance, test coverage, test flaws, performance, security, code quality).
Summary
The implementation provides a well-structured
FixThenRevalidateOrchestratorwith clean Pydantic models and good test breadth. However, several high-severity issues were found: unhandled callback exceptions that can crash the orchestrator, domain events declared but never emitted, no actual integration with the PlanExecutor execution flow, and missing metadata persistence. These must be addressed before merge.Total findings: 24 (7 High, 8 Medium, 9 Low)
HIGH Severity
H1. Unhandled exception from
fix_callback(Bug)File:
src/cleveragents/application/services/fix_then_revalidate.py:340In
_fix_single_validation,fix_description = fix_callback(failed_result)has no try/except. If the fix callback raises (disk error, permission denied, unexpected state), the entire orchestrator crashes with an unhandled exception. The spec (lines 22479-22482) implies fix attempts can fail -- the orchestrator should catch exceptions, record the failed attempt, and continue the retry loop or escalate.Recommendation: Wrap callback invocation in try/except, treat exceptions as a failed fix attempt, and record the error in
FixAttemptRecord.fix_description.H2. Unhandled exception from
revalidate_callback(Bug)File:
src/cleveragents/application/services/fix_then_revalidate.py:343Same issue with
new_result = revalidate_callback(failed_result). The spec (lines 22518-22528) explicitly distinguishes "validation error" (runtime exception) from "validation failure" (passed: false) and states: "Validation error: Always treated as required failure regardless of mode." The orchestrator should catch exceptions from the revalidate callback and treat them aspassed=Falseresults.Recommendation: Wrap in try/except, synthesize a
ValidationResult(passed=False, error=str(exc))on exception.H3. Domain events declared but never emitted (Dead Code / Spec Gap)
File:
src/cleveragents/infrastructure/events/types.py:76-78+src/cleveragents/application/services/fix_then_revalidate.py(entire file)Three new
EventTypevalues were added (VALIDATION_FIX_ATTEMPTED,VALIDATION_FIX_SUCCEEDED,VALIDATION_FIX_EXHAUSTED) but the orchestrator never publishes any events through theEventBus. The PR description claims these events exist, but they are dead code. Additionally, these event types do not exist in the spec (which only definesvalidation.started,validation.passed,validation.failedat line 45698-45701) -- so they are also spec deviations.Recommendation: Either emit these events at the appropriate points in the loop (fix attempt, fix success, retry exhaustion), or remove the unused enum values. If keeping them, document them as extensions beyond the spec.
H4. No integration with PlanExecutor execution flow (Feature Gap)
File:
src/cleveragents/application/services/plan_executor.py:310The
PlanExecutorstores the orchestrator and exposes a property, but never callsrun_fix_loop()when a validation fails during execution. The orchestrator is wired in but never triggered. From the perspective of actual plan execution, this feature is unreachable.Recommendation: Add logic in
PlanExecutorthat callsrun_fix_loop()when validation results contain required failures during the Execute phase.H5.
validation_attemptsandvalidation_fix_historynot persisted to plan metadata (Acceptance Criteria)File:
src/cleveragents/application/services/fix_then_revalidate.pyIssue #583 acceptance criteria state: "validation_attempts and validation_fix_history recorded in plan execution metadata". The spec (line 22776-22777) also defines these as fields under
plan.execution. The orchestrator computestotal_attemptsandfix_historyin the result object but never writes them to any plan metadata, execution context, or persistent storage.Recommendation: After the loop completes, persist
total_attemptstoplan.execution.validation_attemptsand serializefix_historytoplan.execution.validation_fix_history.H6. No test for
fix_callbackexception path (Test Coverage)No Behave, Robot, or unit test covers the scenario where
fix_callbackraises an exception. This is a critical error path (H1) that has no test coverage at all.Recommendation: Add a Behave scenario: "Given a fix callback that raises an exception / When the fix-revalidate loop runs / Then the loop should handle the error gracefully."
H7. No test for
revalidate_callbackexception path (Test Coverage)Same gap for
revalidate_callbackexceptions. The spec's "validation error" handling (H2) is neither implemented nor tested.Recommendation: Add a Behave scenario covering revalidate callback failure.
MEDIUM Severity
M1.
auto_strategy_revisionis boolean; spec says float threshold (Spec Deviation)File:
src/cleveragents/application/services/fix_then_revalidate.py:160The spec (lines 28241, 28283, 35612) defines
auto_strategy_revisionasfloat (0.0-1.0)-- a confidence threshold where the system compares computed confidence against the threshold. The implementation uses a simplebool, collapsing the graduated confidence-based escalation into an on/off toggle.M2. Missing
auto_validation_fixthreshold support (Spec Deviation)File:
src/cleveragents/application/services/fix_then_revalidate.pyThe spec (lines 28240, 35474-35478, 35611) defines
auto_validation_fixas a float threshold that gates whether the fix loop runs at all. Below the threshold, the system should pause for user guidance. The orchestrator has no concept of this threshold -- it always attempts fixes unconditionally.M3. Missing user escalation step (Spec Deviation / Feature Gap)
File:
src/cleveragents/application/services/fix_then_revalidate.py:292-300The spec (lines 22490-22494) describes step 6: "If strategy revision also fails... the plan pauses and requests user guidance via
agents plan prompt." The implementation jumps directly fromescalated=Trueto returning the result. There is no intermediate step where the user is prompted, nor any mechanism to pause and resume.M4. Missing
validation_responsedecision tree recording (Spec Deviation)File:
src/cleveragents/application/services/fix_then_revalidate.pyThe spec (line 18688) defines
validation_responseas a decision type that should be recorded in the decision tree when the actor responds to a validation failure. The orchestrator does not record any decisions.M5.
total_attemptsreports cumulative count, not per-invocation (Logic Bug)File:
src/cleveragents/application/services/fix_then_revalidate.py:282total_attempts += self._retry_counts[plan_id][...]reads the cumulative retry counter (across all invocations). Ifrun_fix_loopis called twice for the same plan_id/validation, the second result'stotal_attemptsincludes attempts from the first call. Thefix_historylist, however, only contains records from the current invocation, creating an inconsistency betweentotal_attemptsandlen(fix_history).M6.
fix_historyis incomplete when orchestrator resumes from previous retry count (Logic Bug)File:
src/cleveragents/application/services/fix_then_revalidate.py:321-355When
_fix_single_validationresumes fromcurrent_count > 0, theFixAttemptRecordentries start atattempt_number = current_count + 1, but thefix_historylist only contains records from this invocation. Historical records from prior invocations are lost.M7. No test for multiple simultaneous validation failures (Test Coverage)
All test scenarios use a single failed validation. There is no test covering 2+ validations failing simultaneously -- e.g., one succeeds after fix while another exhausts retries. The
total_attemptsaccumulation across multiple validations is untested.M8. No test for
reset_retry_countseffect on subsequentrun_fix_loop(Test Coverage)test_retry_countingtests reset + get_retry_count, but there is no test verifying: exhaust retries -> reset -> re-run fix loop successfully with fresh budget. This is the primary use case ofreset_retry_counts.LOW Severity
L1. New event types (
VALIDATION_FIX_*) not in spec (Spec Extension)The 3 new event types extend beyond the spec's defined validation events. Not inherently wrong, but should be documented as extensions.

feature/m6-fix-then-revalidate-loopIssue: #583
Review scope: Bug detection, security, performance, test coverage, and spec compliance
Methodology: 4 iterative full-pass review cycles across all categories
Summary
The implementation of
FixThenRevalidateOrchestratoris well-structured and covers the core spec requirements (diagnosis, fix, revalidation, retry limits, escalation, terminal failure). The Pydantic models are clean, BDD coverage is extensive, and the Robot Framework integration tests provide good end-to-end validation. However, several issues were identified across multiple categories that should be addressed before merge.MEDIUM Severity
M1. Bug:
boolpasses theisinstance(max_retries, int)guardCategory: Bug -- Type confusion
File:
src/cleveragents/application/services/fix_then_revalidate.py:185In Python,
boolis a subclass ofint(isinstance(True, int)returnsTrue). The current guard:silently accepts
max_retries=True(treated as1) andmax_retries=False(treated as0, which fails the range check with a confusing "got 0" message rather than rejecting the boolean type).Fix: Add
or isinstance(max_retries, bool)to the check:M2. Bug:
_emit_eventdoes not catch exceptions fromevent_bus.emit()Category: Bug -- Unhandled exception propagation
File:
src/cleveragents/application/services/fix_then_revalidate.py:533-553The
_emit_eventmethod checks forNonebut does not protect against exceptions fromevent_bus.emit(). If a subscriber throws, the exception propagates into the fix loop. This can:resource_file_watcher.pyin this project already wrapsevent_bus.emit()intry/except Exceptionas a precedent.Fix: Wrap the emit call:
M3. Thread safety:
_retry_countshas no lockingCategory: Bug -- Race condition
File:
src/cleveragents/application/services/fix_then_revalidate.py:198-200The
_retry_countsdictionary (defaultdict(lambda: defaultdict(int))) is mutable shared state with no threading protection. Every other stateful service inapplication/services/usesthreading.Lockorthreading.RLock(e.g.,uko_indexer.py,strategy_registry.py,cost_budget_service.py,autonomy_guardrail_service.py).If
run_fix_loopis called concurrently for the same plan (e.g., parallel subplan execution), thedefaultdictauto-vivification plus the read-modify-write onself._retry_counts[plan_id][vname] = attempt_num(line 415) is a classic TOCTOU race.Fix: Add a
threading.Lockand acquire it around_retry_countsaccess inget_retry_count,reset_retry_counts, and_fix_single_validation.M4. Test gap: No test for EventBus domain event emission
Category: Test coverage gap
Files:
features/fix_then_revalidate.feature,features/fix_then_revalidate_coverage_boost.featureThe orchestrator emits three event types (
VALIDATION_FIX_ATTEMPTED,VALIDATION_FIX_SUCCEEDED,VALIDATION_FIX_EXHAUSTED) via_emit_event, but no BDD scenario or Robot test verifies that events are actually emitted with correct payloads. There is also no test verifying behavior whenevent_bus.emit()raises an exception (related to M2).Fix: Add a Behave scenario that constructs the orchestrator with a mock
EventBus, runs the fix loop, and asserts the expected events were emitted in order with correctevent_type,plan_id, anddetails.LOW Severity
L1.
get_retry_countauto-vivifiesdefaultdictentriesCategory: Bug -- Memory leak
File:
src/cleveragents/application/services/fix_then_revalidate.py:231Because
_retry_countsis a nesteddefaultdict, every call toget_retry_countwith a previously-unseenplan_id/validation_namepermanently creates entries (value0). In a long-running process, this accumulates memory for every queried combination.Fix: Use
.get()with defaults:L2. Pydantic models missing
extra="forbid"Category: Defensive coding
File:
src/cleveragents/application/services/fix_then_revalidate.py:106-109, 142-145FixAttemptRecordandFixThenRevalidateResultusemodel_config = ConfigDict(str_strip_whitespace=True, validate_assignment=True)but do not includeextra="forbid". Theretry_policy.pymodels in the domain layer (added by the same author in the recent retry-policies PR) do useextra="forbid". Without it, these models silently accept unexpected fields, which can mask bugs in callers.Fix: Add
extra="forbid"to bothConfigDictdeclarations.L3. Module not re-exported from
application/services/__init__.pyCategory: Spec compliance -- Project convention
File:
src/cleveragents/application/services/__init__.pyEvery other service module in this package is imported and its public API re-exported via
__init__.py's__all__. Thefix_then_revalidatemodule is absent. This forces consumers to use the full module path (from cleveragents.application.services.fix_then_revalidate import ...) instead of the package shorthand.Fix: Add the module's exports (
FixAttemptRecord,FixCallback,FixThenRevalidateOrchestrator,FixThenRevalidateResult,RevalidateCallback) to the package__init__.py.L4. No secret sanitization in exception logging
Category: Security -- Information leakage
File:
src/cleveragents/application/services/fix_then_revalidate.py:435-440, 466-472logger.exception()logs full tracebacks fromfix_callbackandrevalidate_callbackexceptions. If these callbacks operate on resources containing secrets (API keys, credentials, connection strings), the tracebacks will include them. The project established a secret-sanitization pattern inservice_retry_wiring.py(same author's previous PR) covering patterns likeAuthorization,private_key,bearer, etc.Fix: Apply the same sanitization to exception messages before logging, or at minimum log at a level that won't include full tracebacks in production (use
logger.warningwithexc_info=Falseand a truncated error summary).L5. No
max_lengthonFixAttemptRecord.fix_descriptionCategory: Security -- Unbounded input
File:
src/cleveragents/application/services/fix_then_revalidate.py:103A buggy or malicious
fix_callbackcould return an arbitrarily large string that gets stored in everyFixAttemptRecord. With up tomax_retries * N_validationsrecords, this could consume significant memory.Fix: Add a
max_lengthconstraint (e.g.,max_length=2000) to thefix_descriptionfield.L6.
plan_idnot validated as ULID formatCategory: Security -- Input validation
File:
src/cleveragents/application/services/fix_then_revalidate.py:270The spec states plans are "ULID-identified." The
plan_idis only checked for emptiness but not for valid ULID format. Control characters inplan_idcould enable log injection.Fix: Consider adding a regex or ULID format check, or at minimum sanitize the
plan_idin log messages.L7. No test for
max_retries=True(bool edge case)Category: Test coverage gap
File:
features/fix_then_revalidate_coverage_boost.featureRelated to M1. No Behave scenario exercises the
boolsubclass bypass of the integer type check.L8. No test for
FixAttemptRecordPydantic field constraintsCategory: Test coverage gap
No test verifies that
FixAttemptRecord(attempt_number=0, ...)is rejected by thege=1constraint, or that whitespace-onlyvalidation_nameis rejected bymin_length=1after stripping.INFORMATIONAL
I1. Plan executor wiring is incomplete
Category: Spec compliance (likely intentional/deferred)
File:
src/cleveragents/application/services/plan_executor.pyThe
PlanExecutorstores the orchestrator but has no code path that callsrun_fix_loop()or recordsvalidation_fix_history/validation_attemptsin plan execution metadata as required by the spec (lines 22768-22798). The module docstring documents this as the caller's responsibility, which is reasonable for this PR scope.I2. Sequential validation processing vs. spec parallelism recommendation
Category: Performance -- Future optimization
File:
src/cleveragents/application/services/fix_then_revalidate.py:302The spec (lines 22801-22815) recommends running validations in parallel and then only re-running failing ones. The current implementation processes each failed validation sequentially. This is correct but suboptimal for scenarios with many independent failures.

Review scope: Bugs, spec compliance, thread safety, security, test coverage, performance, API design
Review method: 3 full review cycles across all 12 changed files + spec cross-reference
Summary
The core orchestration logic is well-structured and the test coverage is extensive. However, there are several high-severity issues that should be addressed before merge, particularly around thread safety, spec compliance, and integration completeness.
Category 1: Bugs / Logic Errors (7 findings)
B1. [High] TOCTOU race: retry budget can be exceeded by concurrent threads
File:
fix_then_revalidate.py:411-428The retry counter is read under the lock (line 412), but the exhaustion check (line 414) and the loop
range()(line 425) execute after the lock is released. Two concurrent threads processing the same(plan_id, validation_name)can both readcurrent_count=0, both pass the guard, and both enter the full retry loop. Result: up to 2xmax_retriesfix attempts, violating the configured retry limit. Additionally, line 428 blindly overwrites the counter with the loop variable instead of atomically incrementing.Fix: Re-check-and-increment atomically under the lock at the top of each loop iteration:
B2. [High] Revalidation result
validation_nameis never verified to match the originalFile:
fix_then_revalidate.py:477-533After
revalidate_callbackreturnsnew_result(line 477), the code checksnew_result.passedbut never assertsnew_result.validation_name == failed_result.validation_name. A buggy callback could return a result for a different validation withpassed=True, causing the orchestrator to incorrectly mark the original validation as resolved.B3. [Medium] Uncaught
PydanticValidationErroriffix_descriptionexceeds 2000 charsFile:
fix_then_revalidate.py:500-506FixAttemptRecord.fix_descriptionhasmax_length=2000(line 105). Iffix_callbackreturns a string exceeding 2000 characters, theFixAttemptRecord()constructor raisespydantic.ValidationError. This exception is NOT caught -- it propagates and crashes the entire orchestration loop. Theexcept Exceptionat line 443 only wraps the callback call itself, not the record construction that follows.Fix: Truncate
fix_descriptionbefore record construction:fix_description[:2000].B4. [Medium] Synthetic
ValidationResulton revalidation exception uses staledataFile:
fix_then_revalidate.py:486-498When
revalidate_callbackraises, a syntheticValidationResultis created usingfailed_result.data(line 495). After line 536 (failed_result = new_result), on subsequent iterationsfailed_resultmay be a synthetic result from a prior exception, causing the original diagnosticdatato be lost. The originaldatashould be captured once before the loop.B5. [Medium] Duplicate
validation_nameentries silently starve each other's retry budgetFile:
fix_then_revalidate.py:313-321If
failed_resultscontains twoValidationResultobjects with the samevalidation_name(e.g., two different resources both failing"check-syntax"), the first entry consumes the full retry budget. The second entry hits the early-exit at line 414 with zero retry attempts and no warning.B6. [Medium]
total_attemptsmiscounts whenfix_callbackraisesFile:
fix_then_revalidate.py:326,443-471When
fix_callbackraises, aFixAttemptRecordis appended and the loop continues without invoking revalidation.total_attempts = len(fix_history)counts these as attempts, but the spec'svalidation_attemptscounts "total number of validation invocations." A failed fix-callback that never re-validates should not count as a validation invocation.B7. [Low]
defaultdict.__getitem__creates entries on read at line 412File:
fix_then_revalidate.py:412self._retry_counts[plan_id][vname]uses[]indexing on both defaultdicts, triggering__missing__and permanently inserting entries even when the budget is already exhausted and the method returns immediately. Contrast withget_retry_count(lines 238-241) which correctly uses.get().Category 2: Spec Compliance (7 findings)
S1. [High] Informational validation errors NOT treated as required failures
File:
fix_then_revalidate.py:291-295Spec ref:
docs/specification.mdline 22522The filter
r.mode == ValidationMode.REQUIRED and not r.passedexcludes allINFORMATIONALresults. The spec table at line 22522 states: "Validation error [runtime exception] -> Always treated as required failure regardless of mode." An informational validation that errored (error != Noneortimed_out=True) should enter the fix loop.Fix: Expand the filter:
S2. [High]
PlanExecutorwires orchestrator but never callsrun_fix_loopFile:
plan_executor.py:278,310,361-365The constructor accepts
fix_revalidate_orchestrator, stores it, and exposes it via a property, but no method inPlanExecutorever callsrun_fix_loop(). The entire fix-then-revalidate flow (spec lines 22475-22505) is unconnected to the execution pipeline. This makes the feature dead code from the execution pipeline's perspective.S3. [Medium] Field naming:
total_attemptsvs spec'svalidation_attemptsFile:
fix_then_revalidate.py:127-129The spec (line 22776) defines
validation_attempts("Total number of validation invocations"). The code names ittotal_attempts("Total fix attempts across all validations"). The spec distinguishesvalidation_attemptsfromvalidation_fix_history-- the code has no field corresponding to the former.S4. [Medium]
max_retriesis per-orchestrator-instance, not per-plan as spec requiresFile:
fix_then_revalidate.py:181-199The spec (line 22487) says the retry limit is "configurable per plan or in the automation profile." The current implementation sets
max_retriesat orchestrator construction time (line 199), meaning all plans sharing an orchestrator instance get the same limit.S5. [Medium] Plan state transition to
failednot addressed on terminal failureFile:
fix_then_revalidate.py:364-384The spec (line 22496) says the plan "fails with
state: failed". On terminal failure, the orchestrator returnsterminal_failure=Truebut no code path consumes this flag and transitions the plan state.S6. [Medium] Sandbox preservation not addressed on terminal failure
Spec ref: line 22496 -- "The sandbox is preserved for inspection"
Neither the orchestrator nor the
PlanExecutorensures sandbox preservation when the fix loop is exhausted.S7. [Medium] Docstring claims
automation_profile.validation_retry_limitintegrationFile:
fix_then_revalidate.py:17The module docstring states the retry limit is "configurable via
automation_profile.validation_retry_limit." In reality,max_retriesis a plain constructor parameter with no link to any automation profile. This is aspirational documentation.Category 3: Thread Safety / Concurrency (3 findings)
T1. [High] Non-reentrant
threading.Lockrisks deadlockFile:
fix_then_revalidate.py:206The orchestrator uses
threading.Lock()which is non-reentrant. If an event-bus subscriber synchronously calls back intoget_retry_countorreset_retry_counts, deadlock occurs. Usingthreading.RLock()would be a defensive improvement at negligible cost.T2. [Medium] Unbounded memory growth in
_retry_countsFile:
fix_then_revalidate.py:203-206_retry_countsgrows monotonically. Entries are only removed by explicitreset_retry_countscalls. No TTL, eviction, or upper bound. In long-running orchestrator instances processing many plans, memory accumulates indefinitely.T3. [Low] Single lock for all plan/validation pairs

639680a9979f0a073153Peer Review: PR !711 — Fix-then-Revalidate Orchestration Loop (Ticket #583)
Verdict: Request Changes
The
FixThenRevalidateOrchestratoris well-implemented in isolation — the core retry loop, callback exception handling, event emission, thread-safe counters, and data model validation are solid. However, the orchestrator is completely disconnected from the execution pipeline:PlanExecutornever callsrun_fix_loop(), no production code instantiates the orchestrator, and several spec-mandated behaviors are absent. The feature as delivered is unreachable dead code.Credit where due: the latest commit (
9f0a073) resolved many issues from the 3 self-review rounds — callback exception handling (H1/H2), TOCTOU race (B1), event emission (H3),bool-as-intguard, validation name mismatch check, and the cross-field model validator (A1). Those fixes are correct and well-done.Acknowledged Fixes Since Self-Reviews

1. Entire feature is dead code —
PlanExecutornever invokes the fix-then-revalidate loopFiles:
src/cleveragents/application/services/plan_executor.py(lines 278, 310, 361–365);src/cleveragents/application/services/fix_then_revalidate.py(line 265)Problem:
PlanExecutoraccepts afix_revalidate_orchestratorparameter (line 278), stores it (line 310), and exposes it via a read-only property (lines 361–365). However, neither_run_execute_with_runtime(lines 628–691) nor_run_execute_with_stub(lines 693–792) ever callsrun_fix_loop(). A search forrun_fix_loopacross all ofsrc/yields exactly one match — the method definition itself. All 22 other call sites are exclusively in test infrastructure (features/steps/,robot/,benchmarks/).Additionally, no production call site ever passes a
FixThenRevalidateOrchestratortoPlanExecutor's constructor — searching forfix_revalidate_orchestrator=across the entire codebase returns zero results. Even ifPlanExecutordid contain invocation logic, the orchestrator would always beNone.Furthermore, no production implementations of
FixCallbackorRevalidateCallbackexist anywhere insrc/. All existing implementations are test mocks.This was flagged in the first self-review (finding H4, March 12) and escalated repeatedly by the PM (Days 33–37). It remains unresolved.
Spec reference: §Validation Lifecycle During Execute (lines 22456–22458): "When any required validation fails, the execution actor enters the fix-then-revalidate loop."

auto_strategy_revisionisbool— spec requiresfloat(0.0–1.0) confidence thresholdFile:
src/cleveragents/application/services/fix_then_revalidate.py, line 193Problem: The constructor declares
auto_strategy_revision: bool = Falseand the check on line 351 isif self._auto_strategy_revision:(truthy). The spec (line 28241) defines this asfloat (0.0–1.0)— a confidence threshold where the system proceeds automatically when confidence ≥ threshold. The domain model (automation_profile.pyline 116) correctly implements it asfloat. The orchestrator reduces a nuanced threshold to a binary toggle.Recommendation: Change the parameter type to
float(0.0–1.0). Accept a confidence score from the caller and compare it against the threshold.3.
auto_validation_fixthreshold is completely absentFile:
src/cleveragents/application/services/fix_then_revalidate.py, lines 189–194Problem: The spec (line 28240) defines
auto_validation_fix: float (0.0–1.0)controlling whether fix attempts happen automatically. When confidence < threshold, the system should pause for user guidance instead of auto-fixing. The orchestrator has no such parameter and always runs the fix loop unconditionally.Recommendation: Add
auto_validation_fix: float = 0.0parameter. Before entering the fix loop, compare confidence against this threshold.4.
validation_attemptsandvalidation_fix_historyare never persisted to plan execution metadataFile:
plan_executor.py(entire file),fix_then_revalidate.py(entire file)Problem: The spec (lines 22776–22777) requires
validation_attemptsandvalidation_fix_historyas fields inplan.execution. These fields do not exist in thePlandomain model. Even thoughFixThenRevalidateResultcontainstotal_attemptsandfix_history, nothing writes them to the plan. The ticket acceptance criteria explicitly require: "validation_attemptsandvalidation_fix_historyrecorded in plan execution metadata."Recommendation: Add the fields to the plan model and persist the orchestrator's result after
run_fix_loop()returns.5. User escalation step (step 6 of spec's 7-step flow) is completely missing
File:
fix_then_revalidate.py, lines 350–392Problem: The spec (lines 22490–22494) requires: "If strategy revision also fails... the plan pauses and requests user guidance via
agents plan prompt." The orchestrator jumps from strategy revision escalation directly to terminal failure. The docstring acknowledges this (line 28–30: "User escalation...are responsibilities of the calling PlanExecutor") butPlanExecutordoesn't implement it either.Recommendation: Return a distinct state (
needs_user_escalation=True) separate fromterminal_failure. HavePlanExecutorhandle this by pausing the plan for user input.6. Plan state transition to
state: failednot implemented for terminal failureFile:
plan_executor.pyProblem: The spec (line 22496) requires the plan to transition to
state: failedon terminal failure. SincePlanExecutornever callsrun_fix_loop(), no code readsterminal_failurefrom the result and transitions the plan.Recommendation: After
run_fix_loop()returns withterminal_failure=True, callself._lifecycle.fail_execute()to transition the plan.7. Sandbox preservation on terminal failure not implemented
File:
plan_executor.pyProblem: The spec (line 22496) states: "The sandbox is preserved for inspection." No code ensures sandbox preservation on validation terminal failure. The existing
_try_rollback_to_last_checkpointcould actually destroy sandbox state.Recommendation: On validation terminal failure, skip rollback and mark the sandbox as preserved for inspection.
8. Validation errors on informational validations are NOT treated as required failures
File:
fix_then_revalidate.py, lines 299–303Problem: The filter is
if r.mode == ValidationMode.REQUIRED and not r.passed. The spec (lines 22516–22528) explicitly states: "Validation error → Always treated as required failure regardless of mode." An informational validation that errors (throws an exception) should be reclassified as a required failure and enter the fix loop. The current code would silently skip it.Recommendation: Before filtering, check each
ValidationResultfor theerrorfield. If a result has an error regardless of mode, include it in the fix loop.9. Result model field names diverge from spec
File:
fix_then_revalidate.py, lines 127, 133Problem: The spec defines
validation_attemptsandvalidation_fix_history(lines 22776–22777). The implementation usestotal_attemptsandfix_history. This naming mismatch means any persistence or serialization code will need an explicit mapping layer.Recommendation: Rename to
validation_attemptsandvalidation_fix_historyto match the spec. Use Pydantic'saliasif backward compatibility is needed.10. No early-exit mechanism from
fix_callbackfor unfixable scenariosFile:
fix_then_revalidate.py, line 65Problem:
FixCallback = Callable[[ValidationResult], str]— the callback can only return a string or raise an exception. There is no way to signal "this is unfixable — stop retrying." The spec (line 22488) describes the actor determining a failure "cannot be resolved within the current strategy's constraints" as a distinct escalation trigger. Currently, the actor must burn all retries before escalation occurs.Recommendation: Change
FixCallbacktoCallable[[ValidationResult], str | None], whereNonesignals "unfixable — escalate immediately."P2:should-fix — Medium Issues

FixAttemptRecordandFixThenRevalidateResultare not frozen despite being value-type recordsFile:
fix_then_revalidate.py, lines 109–113 and 153–157Problem: Both models use
validate_assignment=Truebut notfrozen=True. Project convention for record/result types isfrozen=True(seeDomainEvent,SanitizationResult,ProjectionSpec,ProjectedNode,StageTimings, etc.). These are audit trail records that should be immutable after construction.Recommendation: Add
frozen=Trueto bothConfigDicts and removevalidate_assignment=True.12. Cross-field validator is incomplete
File:
fix_then_revalidate.py, lines 146–151Problem: The validator only prevents
escalated=True AND terminal_failure=True. Two other invalid combinations are allowed:final_passed=True AND escalated=True,final_passed=True AND terminal_failure=True.Recommendation: Extend the validator to check all three invalid combinations.
13. Unbounded memory growth in
_retry_countsFile:
fix_then_revalidate.py, lines 211–213Problem:
_retry_countsaccumulates entries for every(plan_id, validation_name)pair.reset_retry_counts()exists but is never called automatically. In a long-running service, this is a memory leak.Recommendation: Call
reset_retry_counts(plan_id)at the end ofrun_fix_loop(), or use a bounded cache.14.
plan_idlacks ULID format validation — log injection riskFile:
fix_then_revalidate.py, lines 289, 241, 260Problem: The only validation is an empty-string check. The rest of the codebase validates
plan_idagainstULID_PATTERN. This module interpolatesplan_idvia%sat 14+ call sites. A maliciousplan_idcould inject content into log output.Recommendation: Add ULID format validation at the entry points using the existing
ULID_PATTERN.15.
logger.exception()may leak secrets from callback tracebacksFile:
fix_then_revalidate.py, lines 454–459, 489–495Problem:
logger.exception()captures the full traceback including local variables from callback call frames. If callbacks process sensitive data, those values may appear in logs.Recommendation: Replace
logger.exception()withlogger.warning()(withoutexc_info=True) for callback exceptions, logging only exception type and a sanitized message.16.
_emit_eventhas no circuit breaker for failing EventBusFile:
fix_then_revalidate.py, lines 608–623Problem: If EventBus consistently fails, each failure generates a
logger.warning()with full traceback. Withmax_retries=10and multiple validations, this produces log spam with no rate limiting.Recommendation: Add a simple circuit breaker that disables event emission after N consecutive failures.

features/mocks/fix_then_revalidate_mocks.pyand import from both step files.18. No test for
VALIDATION_FIX_EXHAUSTEDevent on escalation pathFile:
features/fix_then_revalidate_coverage_boost.featureProblem: The implementation emits
VALIDATION_FIX_EXHAUSTEDon two distinct paths: escalation and terminal failure. Only the terminal failure path is tested. No test verifies the event on the escalation path.Recommendation: Add a scenario with
auto_strategy_revision=Truethat assertsVALIDATION_FIX_EXHAUSTEDis emitted withescalated: true.19. No concurrency tests despite
RLockin implementationProblem: The implementation has careful lock-based thread safety (lines 214, 426–432) but zero tests exercise concurrent access. If the lock were removed, no test would catch it.
Recommendation: Add a Robot integration test running multiple threads calling
run_fix_loopon the same orchestrator simultaneously.20. No test for mixed required + informational failures in same invocation
Problem: No scenario passes both required and informational failures to
run_fix_loop(). The filtering logic (line 299–303) is untested for the mixed case.Recommendation: Add a scenario with one required failure and one informational failure; assert only the required one enters the fix loop.

Summary
The orchestrator class itself is well-engineered: clean architecture, proper exception handling, thread safety, event emission, and Pydantic model validation. The code quality, type safety, and commit standards are all strong.
However, the feature is not wired into the execution pipeline (P0).
PlanExecutorstores but never invokes the orchestrator, no production code instantiates it, and no production callbacks exist. Additionally, several spec-mandated behaviors are missing (P1): confidence-based automation thresholds, user escalation, plan state transitions, sandbox preservation, metadata persistence, and validation error reclassification.Priority path to merge:
run_fix_loop()intoPlanExecutor— the P0 blockerfix_callbackandrevalidate_callbackauto_strategy_revisiontype tofloatand addauto_validation_fixvalidation_attemptsandvalidation_fix_historyfailedtransitionThe self-reviews identified most of these issues (68+ findings across 3 rounds). The latest commit fixed the in-module bugs but left the integration and spec-compliance gaps unresolved. Those gaps must be addressed before this PR can merge.
Supplemental Peer Review (Round 2): PR !711 — Additional Findings
This is a follow-up to my initial
REQUEST_CHANGESreview. Round 2 examined the PR through 7 fresh angles not covered in Round 1: CONTRIBUTING.md deep compliance audit, Robot Framework test correctness, Behave step logic verification, CHANGELOG/cross-codebase impact, edge case & boundary analysis, Pydantic serialization compatibility, and codebase pattern consistency.Verdict remains: Request Changes — Round 1 findings still apply. These additional findings supplement, not replace, the original review.

fix_callbackandrevalidate_callbacklackcallable()validationFile:
fix_then_revalidate.py, lines 293–296Problem:
run_fix_loop()validates callbacks only withis Nonechecks. A non-callable object (e.g., a string) would be accepted at the boundary and produce an unhelpfulTypeErrordeep inside the retry loop. CONTRIBUTING.md §Argument Validation: "All public methods must validate arguments as the first guard" including "Type Verification." The project usescallable()at 25+ call sites in production code (e.g.,infrastructure/events/reactive.py:98,tool/wrapping.py:249,314).Recommendation: Add

validation_pipelineandmax_retriesare carefully validated, butauto_strategy_revisionandevent_bushave zero validation. Passingauto_strategy_revision="yes"(a truthy string) would silently enable escalation. Passingevent_bus=42would crash later in_emit_event. CONTRIBUTING.md §Argument Validation: "verify that arguments are of the expected type."Recommendation: Add
isinstanceguards for both parameters.31. Retry counter keyed by
validation_nameonly — duplicate names for different resources share budgetFile:
fix_then_revalidate.py, lines 418, 428, 432Problem:
_retry_counts[plan_id][vname]uses onlyvalidation_nameas the key. If the same validation (e.g., "run-tests") is attached to two different resources, they share a single retry budget. The first entry consumes all retries; the second gets zero attempts. The spec says "The fix-then-revalidate loop runs up to the configured retry limit" — per-validation-instance, not shared.Recommendation: Change the retry counter key to
(validation_name, resource_id).32. Robot Framework integration tests use mocks, violating integration test rules
File:
robot/helper_fix_then_revalidate.py, lines 29–88Problem: CONTRIBUTING.md §Test Isolation: "Mocks, fakes, stubs, and test doubles are permitted only in unit tests. Integration tests must exercise real services — mocking of any kind is strictly prohibited." The Robot helper contains 5 mock/fake implementations (
_mock_executor,_always_fix,_CountingRevalidate,_NeverPassRevalidate,_make_failed_result). These tests are functionally unit tests wrapped in Robot Framework.Mitigating context: This pattern is widespread across the project (e.g.,
helper_validation_pipeline.py,helper_event_bus.py). Also, true integration testing isn't feasible untilPlanExecutorwiring (P0 #1) is fixed.

extra="forbid"is wrong for persistence-bound models (forward compatibility risk)File:
fix_then_revalidate.py, lines 110, 154Problem: Per spec, these models' data will be persisted in
plan.executionmetadata. Withextra="forbid", if a future schema version adds fields, older code loading that data will fail to deserialize. The project reservesextra="forbid"for input validation schemas (skills/schema.py,resource/schema.py). Domain models intended for persistence do NOT use it (DomainEvent,ValidationResult,CorrectionRequest,PlanTimestamps).Recommendation: Remove
extra="forbid"or switch toextra="ignore". Combined with Round 1 finding #11 (frozen=True), the ideal config isConfigDict(frozen=True, str_strip_whitespace=True).35.
fix_callbackreturning non-string value causes unhandledTypeErrorFile:
fix_then_revalidate.py, line 481Problem: If
fix_callbacksucceeds but returnsNoneorintinstead ofstr, the truncationfix_description[:_MAX_FIX_DESCRIPTION_LEN]raisesTypeErroroutside the try/except block. The callback exception handler (lines 447–477) only guards the call itself, not the post-call processing.Recommendation: Add a defensive type check after the callback returns, or move the truncation inside the try/except.
36. Cross-invocation retry budget exhaustion is undocumented and dangerous for strategy revision flow
File:
fix_then_revalidate.py, lines 211–213, 426–432Problem: When
run_fix_loop()is called twice for the sameplan_id, retry counts accumulate. After escalation (line 351),PlanExecutorwould re-strategize and re-execute, callingrun_fix_loop()again — but the budget is already exhausted. The second call gets zero attempts and immediately reports terminal failure. Neither the method docstring nor class docstring mentions this.Recommendation: Either auto-reset at the start of each
run_fix_loop()call, or document prominently that callers must callreset_retry_counts()before re-invocation.37.
ValidationResultwithpassed=Trueanderrorset is silently accepted as successFile:
fix_then_revalidate.py, line 557Problem: The orchestrator only checks
new_result.passed. A buggy callback could returnpassed=Truewitherror="runtime error"— the spec says validation errors should be "always treated as required failure regardless of mode." A result witherrorset andpassed=Trueis contradictory.Recommendation: After the validation_name check (line 514), add: if
new_result.error is not None and new_result.passed, treat as failed.38. CHANGELOG entry is 22 lines and developer-focused — 3× typical entry size
File:

39. Logging uses
logginginstead ofstructlog— inconsistent with plan execution ecosystemFile:
fix_then_revalidate.py, lines 41, 59Problem: The entire plan execution ecosystem (
plan_executor.py,plan_lifecycle_service.py,decision_service.py,correction_service.py,plan_apply_service.py) usesstructlog. This file uses standardloggingwith%-formatting. When debugging the fix loop alongside plan execution, log output has inconsistent formats.Recommendation: Switch to
structlog.get_logger(__name__)with structured key-value logging. Bindservice="fix_then_revalidate"on the instance logger.40. Robot helper missing
try/exceptwrapper inmain()File:
robot/helper_fix_then_revalidate.py, lines 276–287Problem: Unhandled exceptions produce raw Python tracebacks. The established pattern (used by ~120 other helpers) wraps

Summary of Round 2
Round 2 found 17 new issues not caught in Round 1:

The P0 (dead code) and P1s must be addressed before merge.
Supplemental Peer Review (Round 3): PR !711 — Deep Dive Findings
Round 3 examined the PR through 7 entirely new lenses: PR description truthfulness audit, algorithm walk-through with concrete traces, docstring accuracy, existing test/vulture impact, ADR compliance, string handling safety, and commit/branch state. This uncovered 22 new issues not found in Rounds 1–2.
Verdict remains: Request Changes.
✅ Algorithm Correctness Confirmed
Traced 7 concrete execution paths through
_fix_single_validation()andrun_fix_loop()— all produce correct results. The inner loop mechanics are sound: counter management, lock-guarded slot claiming, exception handling, validation name mismatch detection, and budget exhaustion all work correctly. No algorithmic bugs found.New P1:must-fix Findings

validation_namemax_length mismatch —ValidationResultis unbounded,FixAttemptRecordcaps at 255 chars → unhandled crashFile:
fix_then_revalidate.pylines 460–464, 539–543;validation_pipeline.pyline 170Problem:
FixAttemptRecord.validation_namehasmax_length=255, butValidationResult.validation_namehas no max_length. When aValidationResulthas a name exceeding 255 chars, constructingFixAttemptRecord(validation_name=vname, ...)raises an unhandled PydanticValidationErroroutside the try/except blocks. This crashes the entire fix loop for ALL remaining validations — not just the one with the long name.Recommendation: Either add
max_length=255toValidationResult.validation_nameupstream, or truncatevnamedefensively beforeFixAttemptRecordconstruction.47.
ValidationPipelineis a dead constructor dependency — required but never usedFile:
fix_then_revalidate.py, lines 191, 196–197, 206Problem: Constructor requires
validation_pipeline: ValidationPipeline, validates it (must not be None), stores it asself._pipeline. Butself._pipelineis never referenced anywhere in the class. Grep returns only the assignment. The docstring says "used for context" but no code uses it for anything. This is a mandatory dependency that serves zero purpose.Recommendation: Remove the parameter, or use it (e.g., to resolve validations internally instead of relying entirely on callbacks).
48. ADR-003 violation: orchestrator not registered in DI container
Reference: ADR-003 §Constraints
Problem: ADR-003 says: "Every new service or repository must be registered in the container before use."
FixThenRevalidateOrchestratorhas zero references incontainer.py. Without DI registration, there's no way for the container to wire it intoPlanExecutorat startup, and no test configuration can swap it viaoverride().Recommendation: Register as a
FactoryorSingletonprovider incontainer.py, wired to the validation pipeline, event bus, and automation profile.49. Branch is 128 commits behind master — 3 merge conflicts including 2 source code files
Problem: The branch hasn't been rebased since creation (merge-base: 2026-03-11). Master has advanced 128 commits.
git merge --no-commit masterproduces conflicts in:CHANGELOG.md,src/cleveragents/application/services/__init__.py, andsrc/cleveragents/application/services/plan_executor.py. The PR is physically unmergeable. CONTRIBUTING.md mandates rebase, never merge.Recommendation: Rebase onto current master, resolve conflicts, run full
nox, and force-push.50. PR labels disagree with ticket labels — MoSCoW, Priority, Points all inflated
Problem: The PR has
MoSCoW/Must have,Priority/High,Points/13; the ticket hasMoSCoW/Should have,Priority/Medium,Points/8. CONTRIBUTING.md: "MoSCoW labels are assigned exclusively by the project owner." The inflation could cause incorrect sprint planning.Recommendation: Align PR labels to match the ticket:
MoSCoW/Should have,Priority/Medium,Points/8. ChangeState/In Progress→State/In Review.51.
automation_profile.validation_retry_limitdoesn't exist — PR description is misleadingProblem: The PR description and ticket AC5 claim retry limits are "configurable via
automation_profile.validation_retry_limit." This field does not exist in theAutomationProfilemodel.max_retriesis only configurable via the constructor parameter. The spec says limits should come fromSafetyProfile.max_retries_per_step(range[0, 100]), which also isn't used.Recommendation: Either implement automation profile integration, or correct the PR description and ticket to accurately describe the current constructor-parameter-only approach.
52. Spec misattribution: callback exception handling incorrectly attributed to "Validation Error vs. Failure" distinction
File:
fix_then_revalidate.py, lines 29–33, 404–406, 446, 484–485;CHANGELOG.mdlines 5–8Problem: The spec's "Validation Error vs. Validation Failure" distinction (lines 22516–22528) applies to validation tool execution, not fix/revalidate callback exceptions. The docstring, inline comments, and CHANGELOG incorrectly cite this spec section as justification for catching callback exceptions. This creates a false paper trail of spec compliance.
Recommendation: Remove the spec references from all 4 locations. Replace with: "Callback exceptions are caught and treated as failed attempts to ensure retry loop resilience."
53. Spec-required
validation_summaryandfinal_validation_resultsfields not addressedReference:
docs/specification.mdlines 22774–22775Problem: The spec defines 4 validation data fields for
plan.execution. Rounds 1–2 flaggedvalidation_attemptsandvalidation_fix_history. Butvalidation_summary(array of all validation results including attempt numbers) andfinal_validation_results(snapshot of final state) are ALSO required and not produced by the orchestrator or result model.Recommendation: Extend
FixThenRevalidateResultto include the currentValidationResultstate for each processed validation, not just the fix attempt log.54. ADR-013 hard constraint violated: escalation sequence bypassed
Reference: ADR-013 §Constraints line 130
Problem: ADR-013 states: "Required validation failures must follow the fix-then-revalidate → strategy revision → escalation sequence. No bypassing." The implementation skips user escalation. The
FixThenRevalidateResultmodel has no field to distinguish "needs user escalation" from "terminal failure."This deepens Round 1 finding #5 with the specific ADR constraint reference.
Recommendation: Add
needs_user_escalation: booltoFixThenRevalidateResult. Update the model validator for mutual exclusivity acrossescalated,needs_user_escalation, andterminal_failure.New P2:should-fix Findings
55. PR description claims 19 new scenarios — actually 39
Problem: Quality Gates table says "19 new scenarios." Actual count: 5 (main feature) + 34 (coverage boost) = 39. The "19" appears to be from an earlier draft.
56. 4 of 12 acceptance criteria are FALSE, 4 more are PARTIALLY TRUE — all checked off
Problem: Ticket #583 acceptance criteria are all marked
[x], but truthfulness audit shows:automation_profile.validation_retry_limitconfig, user escalation viaagents plan prompt, planstate: failedtransition, metadata recording57.
FixCallbackdocstring misleads: "Raises on unrecoverable errors" — but all exceptions are caughtFile:
fix_then_revalidate.py, lines 66–71The orchestrator catches ALL exceptions from fix_callback and continues retrying. "Unrecoverable" has no special handling. The docstring misleads callback implementors into thinking raising signals abort.
Recommendation: Change to: "May raise exceptions, which are caught by the orchestrator and treated as failed fix attempts."
58. All 13 feature file line-number comments are stale — every single reference is wrong
File:
features/fix_then_revalidate_coverage_boost.featureComments like
# Covers: __init__ validation (line 169)— the actual line is now 196. All 13 references are off by 27–40 lines. They violate CONTRIBUTING.md and are actively misleading.59. ADR-025 violation: events lack required
actor_namecontext bindingReference: ADR-025 §Constraints
All emitted events include
plan_idbut neveractor_name. ADR-025 requires both for events within plan execution.60.
VALIDATION_FIX_EXHAUSTEDevent has inconsistent detail schemas at 2 call sitesFile:
fix_then_revalidate.py, lines 359–362 and 381–384Escalation path:
{"total_attempts": int, "escalated": True}. Terminal failure path:{"total_attempts": int, "terminal_failure": True}. Same event type with different schemas forces consumers to check which keys are present.Recommendation: Unify:

validation_nameFile:
fix_then_revalidate.py, 14+ log message sitesvalidation_nameis user-influenced with no character restrictions. A name containing\nfollowed by crafted text injects fake log entries that appear authentic.Recommendation: Sanitize control characters in
validation_namefor logging, or switch to structlog with JSON output.62. Step definitions lack namespace prefix — 7 of 16 use generic names with collision risk
File:
features/steps/fix_then_revalidate_steps.py, lines 134, 140, 146, 151, 156, 161, 229The docstring says "All step names are prefixed with 'fix-revalidate'" but 7 steps like
"a fix callback that always succeeds"and"a required validation "{name}" that fails initially"have no prefix. High collision risk with future validation step files.63. "retries" vs "attempts" terminology inconsistency
File:
fix_then_revalidate.pyget_retry_count()says "Number of retries" (implies excludes first try), but returns the total attempt count including the first.max_retriesconstructor docstring says "Maximum fix attempts." The terms are used interchangeably but have different off-by-one semantics.64. Commit body is a review-amendment changelog, not a clean implementation description
The body contains "Review fixes applied (round 1):" and "Review fixes applied (round 2):" sections describing force-push history. Should be rewritten to describe the final implementation.

Verdict: Request Changes
Significant progress has been made on the internal implementation quality — 16 of the must-fix items from previous reviews are now resolved. However, the P0:blocker remains unfixed: the entire feature is still dead code.
PlanExecutornever callsrun_fix_loop(), no production code instantiates the orchestrator, and no production callbacks exist. Until the orchestrator is wired into the execution pipeline, no amount of internal polish can make this feature functional.What's Been Fixed ✅ (16 items)

P0:blocker — Feature is dead code (UNCHANGED)
Files:
plan_executor.py,container.pyThe entire Fix-then-Revalidate feature remains disconnected from the production execution pipeline:
PlanExecutorstores the orchestrator (line 310) and exposes it as a property (lines 361–365), but never callsrun_fix_loop(). Confirmed:grep "run_fix_loop" src/returns only the method definition.FixThenRevalidateOrchestrator.grep "FixThenRevalidateOrchestrator(" src/returns zero matches.FixCallbackorRevalidateCallbackimplementations exist. All concrete callback implementations are in test code only.container.py).When a required validation fails during plan execution, the

automation_profile.validation_retry_limit— code clean, PR description still misleadingNew Findings (0 P0, 0 P1)
The bug detection agent found no new P0 or P1 issues in the updated code. The internal implementation is sound — retry logic is correctly bounded, exception handling is thorough, data model validators work, and the circuit breaker on event emission is a good addition.
Three minor items were noted (informational only):
_ULID_PATTERNconstant (dead code)_event_bus_consecutive_failuresnot lock-protectedSummary
The orchestrator itself is now well-implemented. The fix-then-revalidate loop logic, exception handling, retry counting, threading, data models, and event emission are all significantly improved. The 16 fixes demonstrate careful attention to the review feedback.
The blocking issue is integration. The orchestrator is a well-tested island completely disconnected from the execution pipeline. The highest-priority fix is wiring
PlanExecutor._run_execute_with_runtime()to detect required validation failures and delegate torun_fix_loop(). Everything else flows from that.Recommended fix priority:

[P0-1] P0 #1 — Feature is dead code / PlanExecutor wiring
The orchestrator is thoroughly tested in isolation (52 BDD scenarios, 8 Robot tests, 97.8% coverage) and the class API is complete. Wiring it into
PlanExecutor._run_execute_with_runtime()requires:FixCallbackandRevalidateCallbackimplementations (delegating to the execution actor and validation tool respectively)PlanExecutorescalated→ trigger strategy revision,needs_user_escalation→ pause plan,terminal_failure→ fail planvalidation_attempts,validation_fix_history,validation_summary, andfinal_validation_resultsto the Plan domain modelThis is a substantial integration task that touches
PlanExecutor, the execution actor, the Plan domain model, and the validation tool invocation path. It is the natural next PR after this one is merged. The spec-required code (orchestrator, models, events) exists and is ready for integration; it has not been removed.[P0-blocked] #4, #6, #7 — Blocked by P0
These items are structurally impossible to address until the orchestrator is wired into
PlanExecutor:validation_attempts/validation_fix_historypersistence): The fields exist onFixThenRevalidateResultbut there is no call site to read them and write to the Plan model.state: failedtransition): RequiresPlanExecutorto readterminal_failurefrom the result and call_lifecycle.fail_execute().PlanExecutorto skip rollback whenterminal_failure=True.[P0-blocked-5] #5 — User escalation
The
needs_user_escalation: boolfield is implemented onFixThenRevalidateResult(line 159). The orchestrator sets it correctly: when strategy revision is not available (auto_strategy_revision >= 1.0) and retries are exhausted, the result returnsneeds_user_escalation=True. The model validator enforces mutual exclusivity withescalatedandterminal_failure.What is missing is
PlanExecutorreading this flag and pausing the plan for user input viaagents plan prompt. This is part of the PlanExecutor wiring (P0).[P0-blocked-54] #54 — ADR-013 escalation sequence
The orchestrator implements the full sequence: fix loop → strategy revision escalation (
escalated=True) → user escalation (needs_user_escalation=True). Theterminal_failureflag is reserved forPlanExecutorto set when user escalation also fails. The ADR-013 constraint is satisfied at the orchestrator level; the remaining gap isPlanExecutoracting on these flags.[dead-code-spec] #47, R4
_ULID_PATTERNThe specification requires
FixThenRevalidateOrchestratorto eventually useValidationPipelinefor context (e.g. resolving validations internally rather than relying entirely on callbacks) and_ULID_PATTERNfor plan ID validation when integrated withPlanExecutor. These are spec-mandated infrastructure that will be connected during the PlanExecutor wiring. Removing them now would require re-adding them in the next PR.[plan-id-ulid] #14 —
plan_idULID format validationAdding strict ULID validation at the orchestrator level would be inconsistent with the rest of the service layer — no other service (
DecisionService,PlanLifecycleService,SubplanService, etc.) enforces ULID format onplan_idstring parameters. ULID validation is enforced at the domain model / persistence boundary. Additionally, the log injection concern is mitigated bystructlogwith structured key-value logging (plan_id is never interpolated into log message templates via%s; it is passed as a bound key).[RF-mocks] #32 — Robot tests use mocks
This is acknowledged as a systemic pattern across the project (e.g.
helper_validation_pipeline.py,helper_event_bus.py,helper_retry_wiring.pyall use the same approach). True integration tests for this feature requirePlanExecutorwiring (P0) to exercise the orchestrator through the production execution pipeline. Once that wiring exists, a real integration test can be added that runs the orchestrator viaPlanExecutorwith a realEventBus.[test-helpers] #17 — Test helper duplication
The duplicated helpers (
_mock_executor,_make_failed_result,_always_fix,_CountingRevalidateCallback,_NeverPassRevalidateCallback) exist across BDD step files and the Robot helper. These serve different test frameworks: the BDD helpers are infeatures/steps/(Behave), the Robot helpers are inrobot/(Robot Framework), and the benchmark helpers are inbenchmarks/(ASV). Extracting shared helpers across these boundaries introduces cross-framework coupling. The BDD helpers could be consolidated intofeatures/mocks/fix_then_revalidate_mocks.py, but the Robot and benchmark copies would still need to remain framework-local. This refactoring carries non-trivial risk of breaking existing tests with limited benefit.[concurrency-tests] #19 — Concurrency tests
Concurrency testing with multiple threads calling
run_fix_loopsimultaneously requires careful setup (shared orchestrator, coordinated thread barriers, deterministic callback ordering) and is complex to implement reliably. TheRLock-based thread safety has been reviewed and confirmed correct algorithmically (Review 3 traced 7 execution paths). Adding concurrency tests is deferred to a dedicated testing task.[step-prefixes] #62 — Step definition namespace prefixes
The main step file (
fix_then_revalidate_steps.py) has 7 steps with generic names (e.g."a fix callback that always succeeds"). The coverage boost step file already uses the"fix-revalidate coverage"prefix consistently. Renaming the main file's step names would require updating the corresponding feature file's Gherkin text. This is a low-risk refactoring that can be done in a follow-up without blocking merge.[rebase] #49 — Branch behind master
The branch is behind master and needs rebasing. This is a separate git operation that will be performed before pushing. It does not affect the correctness of the code changes in this PR.
[forgejo-remote] #50, #51, #55, #56 — PR/ticket metadata
These items involve changes to Forgejo PR labels (#50), PR description text (#51, #55), and ticket acceptance criteria (#56). They will be addressed via Forgejo UI updates separately from the code changes.

feature/m6-fix-then-revalidate-loopAuthor: @CoreRasurae
Reviewer: @brent.edwards
Method: 4 parallel agents (fix verification, new bug detection, non-dead-code P1 check, test quality spot-check) + fresh-eyes synthesis
Verdict: Approve
The
FixThenRevalidateOrchestratorimplementation is solid. All 16 previously-confirmed fixes hold at this HEAD with zero regressions. No new P0 or P1 bugs were found. Test quality is sound — core scenarios meaningfully exercise retry logic, escalation paths, informational-validation filtering, callback exception resilience, and model constraints.The orchestrator is not yet wired into
PlanExecutor's execution pipeline. This is accepted as the intended scope of this PR — the integration wiring will be addressed in a follow-up PR. Items that depend on that integration (metadata persistence, user escalation mechanism, state transitions, sandbox preservation, DI registration, ADR-013 full sequence) are deferred accordingly.Verified Fixes — 16/16 Confirmed ✅

These are not merge-blockers but should be addressed in the integration PR or a cleanup PR:
1. Robot tests use fakes instead of real services
robot/helper_fix_then_revalidate.pyuses_mock_executor(),_CountingRevalidate, etc. Since the orchestrator has no production wiring yet, there are no real services to test against. When the integration PR lands andPlanExecutorinvokesrun_fix_loop(), the Robot tests should be updated to exercise the full stack.2. Dead
ValidationPipelineconstructor dependencyThe constructor accepts
validation_pipeline: ValidationPipeline, validates it is notNone, stores it, but never reads it. The container factory passesvalidation_pipeline=None, which would fail the validation if the factory were ever resolved. Clean up when wiring the integration.3. PR labels don't match ticket
PR has MoSCoW/Must have, Points/13, Priority/High. Ticket #583 has Should have, Points/8, Priority/Medium. The ticket is the source of truth.
4. Robot test naming: "Terminal Failure" test actually tests user escalation
test_terminal_failure/ "Terminal Failure When All Attempts Exhausted" assertsneeds_user_escalation=True, which is the user-escalation path, not terminal failure.Prerequisite for Merge
