fix(auto): stop blocking on transients — preflight gate, bounded retries, chain parity, blocked UX

[Q00]

Summary

• ooo auto kept ending sessions as BLOCKED on failures the engine could digest itself, violating the Vision Vision SSOT: ooo auto reaches verified product completion without intervention #1157 terminal contract ("recoverable process or interview non-convergence must not end as BLOCKED"). A full inventory of ~90 mark_blocked sites showed the asymmetry: budgeted paths (repair ×5, evaluate rounds ×3, personas ×5) retry, while every single-shot LLM call died on its first transient failure.
• The feat(evolution): add hidden-checklist convergence loop #1916/RFC: hidden-checklist convergence — run → eval → evolve in one ooo run #1917 convergence loop (run → evaluate → evolve) never applied to default-mode auto at all: auto/adapters.py hardcoded auto_evaluate/auto_evolve: False, and the explicit bool outranks the config defaults. The "no second evaluation owner" rationale only holds for complete-product mode — in default mode nobody evaluated the run.
• Blocked terminals were also silent and unactionable: auto.* events were dropped (no shared EventStore), and resume_capability=NONE printed no next step.

Changes

Seed preflight gate (new, auto/seed_preflight.py)

• Deterministically blocks Seeds whose verification story is fiction before RUN: claimed verify scripts that don't exist, unbound $VARs in verify commands, conceptual paths, and verify_commands referencing files neither existing nor declared in expected_artifacts. Blocks carry open questions for the human instead of letting a fabricated harness reach execution.
• Seed QA score gaming removed: the ambiguity_score := 0.19 forced downgrade is gone; ambiguity demands now block honestly via seed_qa_ambiguity_unrepairable.

Bounded transient retries (Vision #1157)

• auto/pipeline.py: seed QA, evaluator, and lateral_thinker transient failures (timeout / exception / transient .error) now retry 3× with backoff before blocking; budget counters are never consumed by retries; deadline checks preserved. New codes: seed_qa_transient_exhausted, evaluator_transient_exhausted, lateral_transient_exhausted.
• auto/interview_driver.py: one flaky round no longer discards the 50-round interview budget — bounded retry around start/resume/answer calls, and the one-shot closure fallback now also runs on the resume branch. New codes: interview_round_transient_exhausted, interview_backend_transient_exhausted.
• seed_reviewer joins the REVIEW resume set — a pre-run review timeout was a permanent --resume dead end (seed_repairer already had the same treatment).

Chain parity (behavior change — owner attention)

• auto/adapters.py HandlerRunStarter no longer hardcodes the successor-chain opt-out; default-mode auto runs now follow execution.auto_evaluate/auto_evolve config (default ON) and enroll in the feat(evolution): add hidden-checklist convergence loop #1916 run→evaluate→evolve chain for the first time. HandlerSynchronousRunStarter (complete-product) keeps False/False — that pipeline owns EVALUATE/RALPH_HANDOFF itself.

Blocked observability + UX

• New auto.session.blocked event; CLI and MCP drivers share one runtime EventStore so auto.seed_preflight.blocked / auto.seed_qa.blocked / session blocks reach the attention relay instead of being silently dropped (also fixes a wait_for_pending_emits livelock).
• CLI prints a structured blocked panel: stage, reason code, open questions parsed from the blocker, and the real resume command via render_resume_lines; resume_capability=NONE now prints an explicit "not resumable — start a new session" instead of nothing.
• skills/auto documents the new codes with a host playbook: transient-exhausted → auto-resume once before escalating; fact-gap → present open questions as answerable choices, never demand hand-edited YAML first.

Observer clarity for evolve/Ralph generations

• lineage.generation.started now carries an ac_focus block (active/frozen AC indices, active AC descriptions, selection reason) so hosts can narrate "Gen 7: reworking 2/5 ACs (3 frozen by prior PASS evidence)" instead of a bare generation number. Descriptions only — verify_command/output_assertion never enter the block (answer-sheet hiding, regression-tested).
• skills/qa step 3.5 becomes a parallel acting-probe fan-out (process/browser-use/computer-use/artifact probes spawned concurrently); empirical evidence outranks the judge score.

Notes

• Deliberately untouched: run/ralph starter 2-attempt bounds (duplicate-enqueue protection), the preflight gate's zero-repair contract (missing facts go to humans), seed_qa_ambiguity_unrepairable blocking, and the four non-oscillation Ralph stop reasons (budget exhaustion by design).
• Remaining known dead ends (documented in HANDOFF.md): auto_pipeline-tagged blocks and interview ledger-gap non-convergence are still unmapped for --resume; stagnation×safe-default persona pool exhaustion can stamp unstuck_exhausted with zero attempts.
• Tests: 3,186 passed integrated (auto + cli + attention relay + start_auto + run_evaluate chain + skills) plus new suites for preflight, transient retry, interview retry, blocked panel, and generation focus; ruff/mypy clean.

What Improved

• Adds deterministic Seed preflight checks, bounded retry scaffolding, actionable blocked-session rendering, shared runtime event-store wiring, and richer lineage-generation telemetry.
• Restores default-mode run-to-evaluate/evolve policy delegation while retaining a single evaluation owner for complete-product mode.
• Removes the forced ambiguity-score downgrade and adds focused regression tests across the changed boundaries.

Issue Requirements

Requirement	Status
Block fictional Seed verification claims before RUN and return actionable open questions	Partially met — context references, claimed dependencies, and unbound variables block, but missing verify-command programs remain advisory or undetected
Remove forced ambiguity-score gaming and block unrepairable ambiguity honestly	Met
Retry seed QA, evaluator, and lateral-thinker transient failures with bounded backoff without consuming repair budgets	Met
Retry interview backend transients without losing round budget or corrupting durable interview state	Not met — retries can duplicate already-persisted answers and mishandle partially persisted starts
Make transient review and evaluation blockers resumable	Partially met — seed_reviewer, evaluator, and lateral mappings exist, but a deadline-blocked persisted Ralph job remains a permanent dead end
Enable default-mode run-to-evaluate/evolve chain according to operator configuration while avoiding duplicate ownership in complete-product mode	Met
Surface blocked auto events through the shared EventStore and render actionable CLI guidance	Met
Include accurate active and frozen AC focus in generation-started observer events without leaking verification answers	Partially met — answer-sheet fields remain hidden, but the focus can become stale after Wonder
Document host handling for new blocked codes and parallel empirical QA probes	Met

Prior Findings Status

No prior ouroboros-agent review rounds or human review comments were present. Current findings are derived independently from the source snapshot, unified diff, and focused verification.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/pipeline.py:696	BLOCKING	A pipeline deadline during Ralph polling still permanently strands the persisted Ralph job. _enforce_deadline() changes the phase to BLOCKED and overwrites last_tool_name with pipeline_deadline while retaining ralph_job_id. On resume, _has_reconciliable_ralph_resume_checkpoint() rejects the checkpoint because the phase is no longer RALPH_HANDOFF, and _recoverable_phase_for_tool() has no pipeline_deadline mapping, so this branch returns without polling the existing job. A focused runtime probe confirmed both helpers return false or None for that persisted state. Preserve the handoff recovery phase or explicitly route deadline blocks with a Ralph checkpoint back through RALPH_HANDOFF.
2	src/ouroboros/auto/interview_driver.py:2224	BLOCKING	_with_transient_retry() retries every interview exception even though production interview.answer is not idempotent. The handler records and durably saves the answer before ambiguity scoring and next-question generation at src/ouroboros/mcp/tools/authoring_handlers.py:3224 and src/ouroboros/mcp/tools/authoring_handlers.py:3254. If either downstream operation fails, the adapter raises and this loop submits the same answer again; because the stored last round is already answered, the handler treats it as a new follow-up round, duplicating transcript content and consuming interview budget. The same blanket retry also swallows PartialInterviewStartError and retries a now-colliding preallocated ID. Retry only failures proven to occur before durable mutation, or add an idempotency/reconciliation contract for start and answer calls.
3	src/ouroboros/auto/seed_preflight.py:253	BLOCKING	Missing files referenced directly by verify_command are classified as non-blocking, so SeedPreflightReport.passed remains true and the fabricated verification command reaches RUN. This contradicts the gate documentation and PR requirement that verify-command files which neither exist nor are declared artifacts be blocked. A focused probe with python scripts/missing.py returned passed=True and only verify_script_unconfirmed, blocking=False. Root-level commands such as python check.py are not detected by the slash-requiring token regex either. Make these unresolved verification-program references blocking when the workspace check is decidable, and cover root-level and extensionless executable forms.

Follow-up Findings

• src/ouroboros/evolution/loop.py:1459 [warning] lineage.generation.started.ac_focus can describe a different working set from the one actually executed. The event is emitted using focus selected before Wonder runs, but focus is recalculated at src/ouroboros/evolution/loop.py:1738 with wonder_output; challenge questions explicitly reopen previously frozen ACs in src/ouroboros/evolution/focus.py:208. The sole started event is not updated, so observers can announce an AC as frozen even though the generation reworks it. Emit the authoritative focus after Wonder-based selection, or add a subsequent focus-changed event and define which event observers must trust.
  None.

Non-blocking Suggestions

None.

Test Coverage Notes

• Ran the changed preflight, pipeline retry/evaluate/lateral, interview retry, adapter, CLI blocked-panel, lineage-focus, and attention-relay suites with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest; all 187 tests passed.
• Focused runtime probes independently confirmed that a deadline-blocked Ralph checkpoint is not recoverable and that a missing verify script currently passes preflight.
• Existing retry tests use side-effect-free backend stubs and therefore do not cover a handler that persists an answer before returning an error.
• Generation-focus tests exercise event projection directly but do not run a Wonder challenge that changes the eventual execution focus.

Design Notes

The PR moves in the right direction by centralizing preflight, retry, observability, and successor-policy behavior. However, retries must respect durable side-effect boundaries, and observer events must represent the authoritative state actually used for execution.

Design / Roadmap Gate

Default-mode chain ownership and shared EventStore wiring fit the existing architecture. Merge is blocked because the interview retry boundary can corrupt persistent transcript semantics, the preflight gate still permits a stated class of fabricated verification harness, the new focus event can misreport execution scope, and deadline handling can hide a recoverable Ralph checkpoint behind a non-resumable terminal marker.

Directional Notes

Maintainer memory directed additional scrutiny toward replay-safe durable state, especially deadline handling after a Ralph job is checkpointed. The blocker is grounded in the current pipeline state transitions and focused runtime output, not in the recalled prior. The deterministic preflight direction otherwise aligns with the project’s ambiguity-before-execution posture.

Test Coverage

• Ran the changed preflight, pipeline retry/evaluate/lateral, interview retry, adapter, CLI blocked-panel, lineage-focus, and attention-relay suites with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest; all 187 tests passed.
• Focused runtime probes independently confirmed that a deadline-blocked Ralph checkpoint is not recoverable and that a missing verify script currently passes preflight.
• Existing retry tests use side-effect-free backend stubs and therefore do not cover a handler that persists an answer before returning an error.
• Generation-focus tests exercise event projection directly but do not run a Wonder challenge that changes the eventual execution focus.

Merge Recommendation

Request changes. Preserve or reconcile durable interview and Ralph state before retrying or terminalizing, make decidable missing verification programs fail preflight, and emit generation focus only once it matches the actual execution working set. Add regression tests at those real persistence and loop boundaries.

[Q00]

Deep convergence audit at exact HEAD 470c7e70d17dfb5e182212f263ead590caab5943:

The direction is strong in several places: bounded budget-neutral QA/evaluator/lateral retries, a clean default-mode versus complete-product ownership split, shared EventStore blocked UX, removal of ambiguity-score gaming, deterministic actionable preflight structure, and verifier-safe focus projection. The 187 focused changed-area tests also pass.

I nevertheless agree with the current request-changes verdict. The remaining blockers sit on production durability boundaries, not cosmetic test gaps:

1. Preserve and reconcile an existing Ralph job after pipeline_deadline; do not overwrite a recoverable checkpoint into a phase that can never reattach to its persisted ralph_job_id.
2. Make interview start/answer retry replay-safe across partial persistence. answer can save durable state before a downstream failure, and PartialInterviewStartError can leave an already allocated ID. Clean stubs do not prove idempotency here.
3. Block decidable missing verification programs, including root-level python check.py and extensionless executables, instead of letting them pass as advisory.
4. Make generation focus authoritative after Wonder, or emit a defined focus-changed event that observers must prefer.

This is the same convergence boundary that took #1916 eleven review rounds: retry is not enough without atomicity, idempotency, crash-gap recovery, and truthful projection across every observer. #1917 likewise points toward production-shaped persisted-state fault tests rather than side-effect-free stubs.

There is also a roadmap decision to ratify explicitly: #1916/#1917 established Auto as the single evaluation/Ralph owner, whereas this PR narrows that ownership to complete-product mode and delegates default mode to the successor chain. The distinction is plausible and cleanly implemented, but it changes merged ownership wording and should be intentional.

Before re-review, add real-handler post-save fault coverage, deadline-during-Ralph-poll resume coverage with no duplicate enqueue, robust verify-program existence cases, and post-Wonder focus truth. Then clear the prompt-size/module-size failures and provide the required canonical R-run metrics. Until those converge, this PR remains correctly held.

• Restores default-mode run → evaluate → evolve chain delegation while preserving complete-product ownership.

Prior Findings Status

The prior round’s four concerns are maintained after fresh current-snapshot inspection and focused probes: Ralph deadline recovery remains stranded, interview retries remain non-idempotent across persistence, missing verification programs still pass preflight, and generation-start focus can diverge after Wonder. The module-size and required R-run failures are additional current-review blockers.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/pipeline.py:2604	BLOCKING	A deadline firing after Ralph dispatch still strands the persisted job. _enforce_deadline changes the phase to BLOCKED and attribution to pipeline_deadline while retaining ralph_job_id; however, _recoverable_phase_for_tool does not map pipeline_deadline, and _has_reconciliable_ralph_resume_checkpoint only recognizes RALPH_HANDOFF. A focused probe produced status=blocked, preserved job_ralph_existing, and made zero resumer calls. Preserve a recoverable handoff checkpoint or explicitly route deadline-blocked states with an existing Ralph handle back through polling without duplicate enqueue.
2	src/ouroboros/auto/interview_driver.py:2222	BLOCKING	The new interview retry wrapper retries every backend exception while assuming failed calls have no side effects, but the production handler persists the answer before ambiguity scoring and next-question generation at src/ouroboros/mcp/tools/authoring_handlers.py:3254. If that downstream work fails, _unwrap raises and the driver resubmits the same answer; because last_question permits answering after the previous round is already recorded, this can append duplicate transcript rounds. A focused side-effect probe persisted the same answer three times. Retry only pre-commit failures, add an idempotency/round key, or reconcile the persisted interview before replaying. Partial-start persistence needs the same replay-safe treatment.
3	src/ouroboros/auto/seed_preflight.py:244	BLOCKING	The preflight does not enforce its claimed missing-verifier contract. _FILE_TOKEN_RE only recognizes paths containing a directory separator and an extension, so absent root-level programs such as python check.py and extensionless executables such as ./verify produce no findings and pass. Even recognized missing command files are only advisory. Focused probes confirmed both absent commands return passed=True. Robustly identify verification program/file operands and block decidably absent ones unless the Seed declares that the run creates them as expected artifacts.
4	src/ouroboros/evolution/loop.py:1459	BLOCKING	lineage.generation.started is emitted with the pre-Wonder focus, but the actual execution focus is recalculated at line 1738 using Wonder challenges. Because emit_generation_started_once suppresses subsequent events and there is no authoritative focus-changed event, observers can report an AC as frozen even though Wonder reopened it and execution will modify it. Emit the started event after final focus selection or define and consume a later authoritative focus update.

Follow-up Findings

• scripts/check-module-size.py:94 [warning] The repository’s required module-size guard is red on the current snapshot. scripts/check-module-size.py reports auto/interview_driver.py at 2,560 versus a 2,496 budget, auto/pipeline.py at 5,447 versus 5,286, and mcp/tools/auto_handler.py at 2,489 versus 2,488. The associated unit guard fails as well. Extract the new responsibilities rather than growing these grandfathered modules.
• scripts/check-auto-perf-budget.py:219 [warning] This PR changes multiple files under src/ouroboros/auto/, so the mandatory R-run comparison gate applies, but the supplied PR body has no ## R-run comparison section or required metrics. CI is designed to reject that state. Add the canonical baseline/PR comparison, including rounds, per-round wall-clock, terminal reason, and EventStore event count.
  | # | File:Line | Priority | Confidence | Suggestion |
  |---|-----------|----------|------------|------------|
  | 1 | src/ouroboros/auto/adapters.py:267 | Medium | Medium | Explicitly ratify the architectural ownership change: default Auto delegates evaluation/evolution to the successor chain, while complete-product Auto remains the evaluation/Ralph owner. The split is coherent, but it narrows previously merged ownership language and should be an intentional maintainer decision. |

Non-blocking Suggestions

None.

Test Coverage Notes

• Reviewed and ran 363 changed-area unit tests; all passed.
• Ran nine focused Ralph deadline/resume tests; all passed, but none covers the reproduced BLOCKED + pipeline_deadline + persisted ralph_job_id state.
• Ran the auto-boundary guard and Ruff on changed Python boundaries; both passed.
• Ran module-size and perf-budget guard tests: 55 passed and one failed because the real repository exceeds three grandfathered module budgets.
• Focused probes confirmed absent python check.py and ./verify pass preflight, answer retries repeat a persistence side effect three times, and a deadline-blocked Ralph checkpoint never invokes its resumer.
• Mypy and canonical R-run metrics were not independently executed or provided.

Design Notes

The overall decomposition and default-versus-complete-product ownership split are directionally sound. The remaining failures are at durable replay and observer-truth boundaries, where retries and projections must reflect committed runtime state rather than optimistic call-level assumptions.

Design / Roadmap Gate

Default-mode chain delegation and shared EventStore wiring fit existing boundaries. Merge remains unsafe because a persisted Ralph job can become non-resumable, interview retries can duplicate durable transcript state, preflight permits missing verification programs, and the sole generation-start event can misstate the actual working set. Repository module-size and R-run gates also remain unsatisfied.

Directional Notes

Maintainer memory directed scrutiny toward Ralph checkpoint recovery and production-shaped persistence faults, but every blocker above is independently grounded in the current source, executed guards, or focused probes. The deterministic preflight direction aligns with ambiguity-before-execution, but its parser must cover all decidable verification-program forms.

Test Coverage

• Reviewed and ran 363 changed-area unit tests; all passed.
• Ran nine focused Ralph deadline/resume tests; all passed, but none covers the reproduced BLOCKED + pipeline_deadline + persisted ralph_job_id state.

Prior Findings Status

The prior Ralph deadline-resume concern is maintained with fresh current-source evidence. The prior verifier-program concern is modified: root-level python check.py and ./verify are now handled, but versioned Python interpreters still bypass blocking. The prior interview persistence and generation-focus concerns are withdrawn because current code and focused tests now reconcile post-save/partial-start state and emit post-Wonder focus. New current-HEAD blockers are the missing pipeline retry implementation/test mismatch and the still-present forced ambiguity downgrade.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/pipeline.py:2050	BLOCKING	The advertised bounded transient retries for pipeline Seed QA/evaluator/lateral calls are absent from current source. _run_seed_qa_gate invokes the evaluator once and immediately returns advisory on the first timeout, exception, or .error; _repair_seed_after_qa likewise falls back after one lateral failure. The newly added retry suite confirms the source/test mismatch: all six tests error during setup because _TRANSIENT_RETRY_BACKOFF_SECONDS does not exist, and the production module also defines no _TRANSIENT_TOOL_ATTEMPTS. This leaves the primary Vision #1157 behavior unchanged and ships a failing test file.
2	src/ouroboros/auto/pipeline.py:2330	BLOCKING	A deadline reached while an already-dispatched Ralph job is checkpointed still strands that job. _enforce_deadline writes last_tool_name="pipeline_deadline" and mark_blocked changes the phase from RALPH_HANDOFF to BLOCKED. On resume, _has_reconciliable_ralph_resume_checkpoint rejects the checkpoint because it requires the phase still be RALPH_HANDOFF, and recoverable_phase_for_tool("pipeline_deadline") returns None. The persisted ralph_job_id is therefore never polled or reconciled, despite the comments claiming this path remains recoverable.
3	src/ouroboros/auto/pipeline.py:2903	BLOCKING	The PR body says ambiguity-score gaming was removed, but both deterministic and lateral Seed-QA repair paths still forcibly lower metadata.ambiguity_score to 0.19 whenever reviewer text requests ambiguity repair. _SEED_QA_AMBIGUITY_REPAIR_SCORE = 0.19 remains at line 2953, and existing tests explicitly require this downgrade. An unresolved ambiguity finding can therefore still be converted into a passing numeric score without new evidence instead of producing the promised seed_qa_ambiguity_unrepairable block.

Follow-up Findings

• src/ouroboros/auto/seed_preflight.py:288 [warning] Missing verification programs remain bypassable through ordinary versioned interpreter names. _command_program_tokens recognizes only a hard-coded set including python3.12; for python3.11 check.py or the current environment’s python3.14 check.py, the missing check.py is classified only as non-blocking verify_script_unconfirmed. A focused runtime probe produced two advisory findings and report.passed == True. The interpreter operand is unambiguously the verification program, so supported Python-version spelling must not decide whether a fabricated harness blocks.

Test Coverage Notes

• Ran the changed-area suites excluding the broken pipeline retry module: 259 passed in 65.23 seconds.
• Running all selected changed-area suites produced 75 passes and 6 setup errors, all from tests/unit/auto/test_pipeline_transient_retry.py:50 patching the nonexistent _TRANSIENT_RETRY_BACKOFF_SECONDS.
• Directly probed python3.11 check.py against an empty workspace; preflight returned only non-blocking verify_script_unconfirmed findings.
• Interview post-save reconciliation and post-Wonder focus regressions are covered by focused tests and passed.
• No focused test currently exercises deadline expiration after a durable Ralph dispatch followed by process resume.

Design Notes

The extraction of preflight, resume routing, terminal events, and interview recovery into focused modules is directionally sound. The remaining failures are at semantic boundaries: retries are documented and tested but not implemented, deadline terminalization destroys Ralph recovery routing, and metadata/parser shortcuts can misrepresent Seed executability and ambiguity.

Design / Roadmap Gate

Default-chain delegation, shared EventStore ownership, interview reconciliation, and post-Wonder focus fit the current architecture. The gate fails because durable Ralph identity becomes unreachable after deadline terminalization, the promised transient policy is missing from production code, the Seed QA path still rewrites ambiguity evidence, and preflight behavior depends on an incomplete interpreter-name allowlist. These are runtime, persistence, and contract-integrity failures rather than cosmetic gaps.

Directional Notes

Maintainer memory was used only to prioritize replay-safe Ralph state and deterministic preflight completeness. Each blocker is independently supported by the current source snapshot, focused test output, or a direct runtime probe. The ambiguity-before-execution direction supports the preflight gate, but the gate must consistently block every decidable verification-program form.

What Improved

• Adds deterministic Seed preflight checks, replay-aware interview retries, actionable blocked-session events and CLI UX, shared runtime EventStore wiring, and authoritative post-Wonder AC focus projection.
• Default Auto run handoffs preserve successor-chain ownership, while retired complete-product phases are explicitly migrated rather than resumed unsafely.

Issue Requirements

Requirement	Status
Deterministically block fabricated or unbound Seed verification claims before RUN	Partially met — core cases work, but versioned/non-allowlisted interpreter forms remain advisory
Remove forced ambiguity-score downgrading	Not met — repair helpers still force qualifying scores to 0.19
Retry Seed QA, evaluator, and lateral transient failures three times without consuming semantic budgets	Not met — production retry machinery is absent and the new test suite errors
Retry transient interview start/resume/answer failures with persistence reconciliation	Met
Make seed_reviewer failures resumable through REVIEW	Met
Preserve default Auto run/evaluate/evolve chain ownership	Met
Emit observable blocked-session events through a shared runtime EventStore	Met
Render actionable blocked CLI guidance, including non-resumable sessions	Met
Emit authoritative, answer-sheet-safe post-Wonder AC focus	Met
Add parallel acting-probe guidance to the QA skill	Met
Keep changed modules within the module-size ratchet	Not met
Provide the maintainer-requested filled canonical R-run comparison	Not met

Prior Findings Status

Prior concerns are modified rather than copied wholesale. The pipeline retry, ambiguity-score integrity, and generic verification-program findings remain independently reproducible at the current snapshot. The former Ralph deadline/resume concern is withdrawn because current main has retired Auto-owned complete-product phases and explicitly migrates legacy RALPH_HANDOFF state. Interview persistence reconciliation and post-Wonder focus concerns are resolved by current code and focused tests. Module-size and required R-run evidence remain unsatisfied.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/pipeline.py:2049	BLOCKING	The advertised pipeline transient-retry policy is not implemented. Seed QA still performs one asyncio.wait_for and immediately returns advisory output on timeout, exception, or .error; there are no _TRANSIENT_TOOL_ATTEMPTS, backoff, or seed_qa_transient_exhausted paths. The newly added test_pipeline_transient_retry.py suite errors during setup because _TRANSIENT_RETRY_BACKOFF_SECONDS does not exist, and its evaluator/lateral cases target constructor parameters and methods removed with complete-product retirement. Implement the bounded retry contract on the surviving production boundary and rewrite the tests against the current architecture.
2	src/ouroboros/auto/pipeline.py:2903	BLOCKING	Seed QA repair still rewrites ambiguity evidence to 0.19, directly contradicting the PR’s claim that score gaming was removed. Both deterministic and lateral repair helpers assign min(existing_score, 0.19) whenever QA requests the readiness threshold; a direct probe changed a real 0.40 score to 0.19 without new interview evidence. Preserve the measured score and block or re-interview when ambiguity remains above the gate.
3	src/ouroboros/auto/seed_preflight.py:288	BLOCKING	Verification-program detection depends on an incomplete hard-coded interpreter allowlist. Missing check.py is blocking under python3.12 but merely advisory under equally decidable python3.11, python3.13, or pypy3, allowing fabricated verification programs to reach execution. Recognize versioned Python/interpreter runner forms generically and add regression cases outside the single allowlisted version.

Follow-up Findings

• src/ouroboros/mcp/tools/subagent.py:847 [warning] The change grows the grandfathered subagent.py module past its ratcheted budget. Running python scripts/check-module-size.py fails with 2653 lines, budget 2639 (+14). Extract the new prompt-bounding behavior into an appropriately scoped module instead of increasing this grandfathered file.
• /tmp/pr_body_Q00_ouroboros_1944.md:46 [warning] The maintainer-required canonical R-run comparison remains entirely N/A, despite the latest contributor comment saying filled metrics are present. This PR changes Auto retries, waits, prompts, and event behavior, so the requested baseline/current rounds, wall-clock, terminal reason, and EventStore count evidence must be supplied before merge.

Test Coverage Notes

• Ran targeted changed-area tests with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest.
• Preflight, interview retry, blocked UX, attention relay, deadline, and generation-focus coverage produced 51 passes in the first group and 4 passes in the focused persistence/panel group.
• All 6 tests in tests/unit/auto/test_pipeline_transient_retry.py errored because the production retry constants are absent.
• Direct probes confirmed version-dependent preflight classification and the 0.40 -> 0.19 ambiguity-score rewrite.
• python scripts/check-module-size.py failed on src/ouroboros/mcp/tools/subagent.py.

Design Notes

The extraction of recovery, preflight-gate, resume-routing, and terminal-event helpers is directionally sound. The current patch nevertheless mixes that architecture with stale pre-retirement transient tests and retains two contract-integrity shortcuts in production.

Design / Roadmap Gate

Default successor-chain ownership, interview reconciliation, blocked observability, and post-Wonder focus fit current architecture. The gate fails because the central transient-retry contract is absent from the surviving production pipeline, Seed metadata remains falsifiable by repair code, verifier classification varies by interpreter spelling, the module-size ratchet fails, and required performance evidence is missing.

Directional Notes

Maintainer memory focused inspection on replay-safe durable state and deterministic preflight completeness. Current source independently shows complete-product/Ralph ownership has since been retired from Auto, so the old deadline blocker is not re-raised. The ambiguity-before-execution direction supports this preflight gate, but only if all decidable program forms are classified consistently and ambiguity evidence is never rewritten.

Test Coverage

• Ran targeted changed-area tests with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest.
• Preflight, interview retry, blocked UX, attention relay, deadline, and generation-focus coverage produced 51 passes in the first group and 4 passes in the focused persistence/panel group.
• All 6 tests in tests/unit/auto/test_pipeline_transient_retry.py errored because the production retry constants are absent.

What Improved

• Adds bounded, budget-neutral retries and persistence reconciliation for active Seed-QA, lateral-repair, and interview backend calls.
• Preserves ambiguity evidence, shares runtime EventStore ownership, improves blocked-session UX, and emits post-Wonder generation focus.
• Extracts prompt-budget logic and satisfies formatting, lint, and module-size checks.

Retry behavior remains replay-safe across partially persisted interview start/answer operations	Met
Deterministically block Seeds whose claimed verification programs do not exist	Partially met
Preserve truthful ambiguity scores and block unrepairable ambiguity	Met

Provide the required canonical R-run comparison and budget determination	Not met

Prior Findings Status

Prior interview replay-safety, Ralph retirement/recovery, ambiguity-score mutation, post-Wonder focus, and module-size concerns are withdrawn because current source and focused tests address them. Preflight completeness remains, modified to the currently reproducible interpreter-option/path/wrapper cases. The missing canonical R-run evidence also remains based on the current PR body.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:295	BLOCKING	The missing-verifier gate only recognizes an explicit ./program in token position zero or a file immediately following an exact runner token. Common, fully decidable forms such as python -u check.py, /usr/bin/python3 check.py, sh -c "python check.py", and bash -c ./verify are classified as non-blocking verify_script_unconfirmed, so preflight passes and a fabricated verifier reaches RUN. A direct probe against current code reproduced all four cases. Parse runner options, path-qualified interpreters, and shell-command operands, with regression tests proving missing programs block.

Follow-up Findings

• /tmp/pr_body_Q00_ouroboros_1944.md:46 [warning] The required R-run comparison remains entirely N/A, despite this PR changing active Auto retry/backoff, preflight, prompt, and EventStore behavior. The accompanying claim that the PR adds no waits, retries, or EventStore writes contradicts the changed code, which adds retry backoffs and blocked events. This does not provide the canonical performance evidence repeatedly required in prior review rounds; supply baseline/current measurements and the resulting budget determination.

Test Coverage Notes

• Ran 268 focused tests covering preflight, pipeline retries, interview persistence/retry, blocked CLI UX, generation focus, scoped re-execution, and attention relay; all passed.
• ruff check passed for all changed Python files and tests; ruff format --check reported all 26 checked files formatted.
• scripts/check-module-size.py passed: 589 modules, cap 2000, 26 grandfathered.
• Direct preflight probes exposed the untested runner-option, path-qualified interpreter, and shell-wrapper cases described in Finding 1.
• Full repository pytest and mypy were not run.

Design Notes

The ownership split, recovery helpers, thin preflight gate, shared EventStore, and post-Wonder focus projection fit the architecture. The verifier-program parser remains too syntactic for its fail-closed contract.

Design / Roadmap Gate

Interview persistence reconciliation and generation-focus truth now satisfy their changed boundaries, and retired complete-product phases are handled explicitly. The gate still fails because common decidable verification-command forms bypass the new preflight blocker, allowing a fictional harness into execution, and the required runtime-performance evidence remains absent.

Directional Notes

Review focused on ambiguity-before-execution, replay-safe durable state, truthful observer projections, and thin boundary handlers. Maintainer memory only directed inspection; both blockers are independently grounded in current source, PR-body evidence, and direct execution.

What Improved

• Adds bounded, budget-neutral retries and persistence reconciliation around interview and active Seed-QA/lateral calls.
• Preserves truthful ambiguity metadata and blocks ambiguity requiring new interview evidence.
• Improves blocked-session observability, resume guidance, and generation focus reporting without exposing verification answer sheets.
• Restores default-mode run→evaluate→evolve chain ownership while retaining the intended ownership split.

Issue Requirements

Requirement	Status
Deterministically block fictional or missing verification programs before RUN	Partially met — newly tested simple, wrapped, versioned, and extensionless forms block, but option-bearing and absolute script operands still bypass the gate
Keep recoverable transient failures from immediately ending Auto as BLOCKED	Met — active interview, Seed-QA, and lateral call sites use bounded retries or advisory fallback

Supply a measurable canonical R-run comparison within the 1.5× budget or an approved exception	Not met
Validate changed behavior and quality gates	Partially met — focused tests and static checks pass, but the full-suite and canonical performance claims were not independently established

Prior Findings Status

Prior interview persistence, Ralph deadline recovery, ambiguity-score integrity, generation-focus truth, and module-size concerns are withdrawn based on current source and focused tests. The verifier-completeness concern is maintained but narrowed to newly proven option-arity and absolute-path bypasses. The canonical R-run evidence concern remains.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:310	BLOCKING	The verification-program parser still lets decidably missing scripts pass preflight. It skips every runner option as though it consumes no operand, so python -X dev check.py and python -W error check.py classify dev/error as the program and downgrade the absent check.py to advisory. Absolute operands are also normalized inconsistently: /usr/bin/python3 /definitely/missing/check.py is matched as relative definitely/missing/check.py, no longer equals the absolute program token, and passes. A direct current-snapshot probe confirmed all three commands return report.passed=True. Parse option arity and preserve absolute operands, with blocking regressions for these forms.

Follow-up Findings

• .github/PULL_REQUEST_TEMPLATE.md:18 [warning] The required canonical R-run comparison remains unmeasured. The PR body reports zero completed rounds, marks per-round cost “Not measurable,” and gives an indeterminate ratio, while the repository contract requires actual per-round wall-clock comparison against the latest baseline and a 1.5× budget. The stated provider stall supplies no positive evidence that these retry and interview-path changes meet the performance boundary. Provide a completed canonical branch run or the separately approved performance-budget exception required by the template.

Test Coverage Notes

• Ran all ten changed test modules: 320 tests passed (88 passed in 4.50s plus 232 passed in 90.38s).
• Ruff check and formatting checks passed for the changed Python source files.
• Mypy passed for seven new/extracted boundary modules.
• Manual module-size inspection remains within the checked-in ratchet limits.
• Direct adversarial probing exposed uncovered preflight failures for Python options with operands and absolute verification-script paths.
• The full 3,186-test claim was not independently rerun, and no successful canonical R-run performance measurement is available.

Design Notes

The ownership split, persistence reconciliation, advisory Seed-QA path, and observer projections fit the current architecture. The remaining implementation defect is localized to deterministic command parsing, while the missing performance evidence leaves a required operational boundary unverified.

Design / Roadmap Gate

Durable interview and Ralph recovery contracts now retain the state needed for replay without duplicate dispatch. Default successor-chain ownership and shared EventStore wiring are coherent, and generation focus matches the execution working set. The gate still fails because caller-controlled verification commands can evade an advertised deterministic safety check, and the repository’s required performance boundary has no completed measurement.

Directional Notes

Maintainer memory directed scrutiny toward replay-safe Ralph/interview state and deterministic preflight completeness. Current source and tests independently support withdrawing the durability concerns; the remaining preflight blocker comes from a fresh runtime probe. The ambiguity-before-execution posture supports blocking objectively missing verifier programs, not downgrading them to advisory because of parser spelling.

Test Coverage

• Ran all ten changed test modules: 320 tests passed (88 passed in 4.50s plus 232 passed in 90.38s).

• Adds shared EventStore blocked-session observability and structured CLI guidance.
• Adds generation AC-focus projections while keeping verification details out of observer payloads.

Issue Requirements

Requirement	Status
Vision #1157: recoverable transient failures must use bounded retries rather than immediately ending as BLOCKED	Partially met — retries exist, but interview retries can duplicate persisted answers when reconciliation is unavailable.
Deterministic preflight must reject fictional or unexecutable verification claims before RUN	Partially met — covered Python, shell-wrapper, and extensionless cases pass, but several direct and alternate-runtime forms remain advisory.
Seed QA ambiguity evidence must remain truthful; no forced ambiguity_score = 0.19 downgrade	Met — current repair path preserves the score and uses an explicit ambiguity blocker.
Default-mode auto must participate in the configured run → evaluate → evolve chain	Met — current HandlerRunStarter omits successor overrides so execution configuration owns the chain.
Blocked sessions must be observable and provide actionable resume/new-session guidance	Met for covered paths — shared EventStore, relay events, and CLI blocked panels are present; raw blocker sanitization remains a blocking boundary issue.
Generation observers must receive truthful active/frozen AC focus without exposing verification answers	Met — focused tests pass and the payload contains descriptions/indices only.
Required R-run comparison must include usable canonical performance evidence	Partially met — the section is present, but the recorded run completed zero rounds and is explicitly indeterminate.

Prior Findings Status

Earlier Ralph deadline/recovery and generation-focus concerns are withdrawn based on the current source and focused tests. The default-chain ownership, shared EventStore wiring, ambiguity-score handling, and ordinary retry paths have converged. A fresh reconciliation-failure probe nevertheless shows that the interview retry boundary can still duplicate durable answers, so that concern is maintained in a narrower current-head form. The deterministic preflight concern is also maintained because additional common executable forms still bypass blocking. The performance-evidence concern remains unresolved.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/interview_recovery.py:55	BLOCKING	Interview retries are not replay-safe when reconciliation is inconclusive. with_transient_retry() retries the original operation after reconcile() raises or returns None; for interview.answer, the production handler persists the response before downstream scoring/question generation. If that call commits and loses its response, then the follow-up resume() is temporarily unavailable, the retry submits the same answer again and duplicates the persisted transcript. A direct probe of this helper produced two durable answer entries from one logical answer. Require an idempotency key or fail closed until the committed operation can be reconciled, and add a production-shaped fault test covering “commit → response loss → reconciliation failure.”
2	src/ouroboros/auto/seed_preflight.py:300	BLOCKING	The advertised deterministic verifier gate still has bypasses for clearly decidable missing programs. _command_program_tokens() only treats ./... as a direct executable and only recognizes a narrow runner allowlist; /definitely/missing/verify.sh, ../scripts/verify.py, /bin/bash -c "/definitely/missing/verify.sh", python3.14t check.py, pypy3 check.py, and python --check-hash-based-pycs always check.py all passed without a blocking verify_program_missing finding in a fresh probe. These commands can reach RUN with a fictional verifier despite the PR’s preflight contract. Generalize executable/operand parsing or explicitly constrain and document supported command forms, with regressions for absolute, parent-relative, version-suffixed, alternate-runtime, and option-bearing commands.
3	src/ouroboros/auto/terminal_events.py:22	BLOCKING	The new durable auto.session.blocked projection copies the raw blocker text into EventStore and attention-relay evidence. Several current blockers interpolate provider/handler exception text, while the authoring layer already has an event-specific redaction helper for paths and diagnostics. A provider error containing credentials, local paths, or stderr can therefore cross the new shared EventStore/relay boundary. Emit an allowlisted error code/category and sanitized detail instead, and test secret/path-containing exceptions.

Follow-up Findings

• /tmp/pr_body_Q00_ouroboros_1944.md:44 [warning] The required R-run evidence is not complete: this PR reports zero completed rounds, an indeterminate per-round cost, and a manually interrupted provider stall. The body explicitly says the canonical comparison must be rerun, so the required performance boundary remains unverified.

Test Coverage Notes

• Targeted changed-area validation passed: 323 passed in 91.53s.
• scripts/check-module-size.py passed with module-size: OK.
• Direct adversarial probes reproduced the verifier-parser bypasses and the interview duplicate-replay behavior.
• The full suite and a completed canonical R-run were not available; the PR body records the canonical attempt as stalled and manually stopped.

Design Notes

The PR fits the existing Auto architecture and improves ownership, observability, and preflight separation. The remaining risks are at replay, executable classification, and durable error-projection boundaries rather than general design direction.

Design / Roadmap Gate

The default successor-chain split and generation-focus projection are compatible with the current architecture. However, retrying a possibly committed interview answer without an idempotency/reconciliation guarantee violates the durable transcript contract; the preflight parser does not cover all decidable executable forms despite being a safety gate; and the new blocked-event boundary forwards unsanitized exception-derived text into durable attention evidence. The performance gate is structurally present but lacks completed canonical evidence.

Directional Notes

Review focus followed the project’s current emphasis on replay-safe durable state, truthful verification gates, bounded retry semantics, and persistent setup/observer boundaries. Maintainer memory was used only to prioritize inspection; all blockers above are grounded in current source or fresh probes.

Prior Findings Status

The prior Ralph deadline/recovery, blocked-event sanitization, and generation-focus concerns are withdrawn based on current source inspection and passing focused tests. The interview durability concern is modified rather than resolved: the new reconciliation branch prevents some duplicate retries, but matching question text still cannot prove that a post-save answer was not committed. The verifier-parser concern remains maintained with fresh bypass probes covering runner options and shell command structure. The performance-evidence concern remains maintained because the current PR body still reports zero completed canonical rounds and requests a future rerun rather than providing completed evidence or an approved exception.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/interview_driver.py:1291	BLOCKING	Answer retry reconciliation treats matching question text as proof that the previous answer was not committed. Question text is not a unique turn or idempotency key. A backend can durably save the answer, fail while generating the next question, and then return an identically worded pending question; this branch returns retry_safe=True and replays the answer. A fresh probe reproduced two durable answer attempts for one interview round while the driver reported seed_ready. Add a server-side idempotency/turn identity or fail closed whenever commit status cannot be proven.
2	src/ouroboros/auto/seed_preflight.py:313	BLOCKING	The advertised deterministic verifier gate still misses decidable executable forms. The parser only treats the first non-option operand after a recognized runner as the program and does not model runner options, shell command separators, or later executable commands. Fresh probes such as node --require preload.js missing.js, ruby -I lib missing.rb, bash -O extglob ./missing-verify, and FOO=bar echo ok; ./missing-verify all passed with only advisory findings, allowing a missing verifier to reach execution. Generalize command parsing or narrow the gate’s claim; add regressions for option-bearing runners and shell command lists.

Follow-up Findings

• /tmp/pr_body_Q00_ouroboros_1944.md:44 [warning] The PR’s required canonical R-run performance evidence remains incomplete: the reported attempt completed zero rounds, has no measurable per-round cost or ratio, and is explicitly marked as a provider stall/manual interruption. The body requests a rerun in CI or an authenticated provider environment, but no completed comparison or approved performance-budget exception is supplied. The runtime-boundary change therefore lacks the required evidence that retry and orchestration changes stay within the project’s performance budget.
  | # | File:Line | Priority | Confidence | Suggestion |
  |---|-----------|----------|------------|------------|
  | 1 | HANDOFF.md:32 | Medium | High | Reconcile the handoff text with the surviving implementation: it documents seed_qa_transient_exhausted, evaluator_transient_exhausted, and lateral_transient_exhausted, but the current Seed-QA path continues through advisory handling rather than emitting those documented blocker codes. |

Non-blocking Suggestions

| 1 | src/ouroboros/auto/seed_preflight.py:281 | Test coverage | Add parser tests for command lists, shell assignments, node/ruby option operands, and executable paths appearing after wrappers or separators so the preflight contract remains explicit as supported command forms expand. |

Test Coverage Notes

• Ran the changed-area suites covering Seed preflight, pipeline preflight, interview retries, pipeline retries, lateral repair, blocked CLI UX, generation focus, scoped reexecution, and attention relay: 146 passed.
• Ran the additional interview-pipeline, pipeline-preflight, attention-relay, and blocked-panel suites: 220 passed.
• Fresh runtime probes reproduced the interview duplicate-answer case and multiple verifier-parser bypasses despite the passing self-authored regression suites.
• No full integrated suite, Ruff, mypy, module-size check, or completed authenticated canonical R-run was independently verified in this review.

Design Notes

The overall design is directionally coherent: deterministic preflight sits before execution, retries are separated from budget counters, default-mode chain ownership is delegated to the run starter, and durable blocked events use generic sanitized payloads. The remaining problems are at two critical contract boundaries: retry replay safety and completeness of the executable-verifier classifier.

Design / Roadmap Gate

The preflight and retry changes affect persisted interview state and the boundary between generated Seed claims and actual execution. A retry is safe only when the system can identify whether the prior operation committed; comparing free-form question text does not provide that identity. Likewise, a deterministic safety gate must classify every supported executable form it claims to inspect, including runner options and shell command lists. The changed observer and generation-focus boundaries otherwise preserve sanitized payloads and description-only focus data. The performance gate remains open because no completed canonical provider-backed measurement establishes compatibility with the stated budget.

Directional Notes

Review focus followed the project’s stated emphasis on replay-safe durable state, truthful preflight gates, bounded retries, observer correctness, and thin runtime boundaries. Maintainer-memory guidance was used only to prioritize inspection; the blocking findings above come from current source inspection and fresh runtime probes. The explicit PR-body performance requirement was also checked separately because the submitted R-run table records an indeterminate result rather than completed evidence.

Test Coverage

• Ran the changed-area suites covering Seed preflight, pipeline preflight, interview retries, pipeline retries, lateral repair, blocked CLI UX, generation focus, scoped reexecution, and attention relay: 146 passed.
• Ran the additional interview-pipeline, pipeline-preflight, attention-relay, and blocked-panel suites: 220 passed.
• Fresh runtime probes reproduced the interview duplicate-answer case and multiple verifier-parser bypasses despite the passing self-authored regression suites.
• No full integrated suite, Ruff, mypy, module-size check, or completed authenticated canonical R-run was independently verified in this review.

Merge Recommendation

Request changes. Resolve answer retry idempotency/reconciliation, close the verifier-parser bypasses with production-shaped regressions, and provide the required completed canonical R-run evidence or an explicitly approved performance exception. The other inspected boundaries show substantial convergence.

• Removes forced ambiguity-score downgrading and restores default Auto successor-chain ownership.
• Shares the runtime EventStore, emits sanitized blocked events, improves CLI recovery guidance, and adds generation AC-focus observability.

Prior Findings Status

The exact Round 44 shell-created-variable concern is withdrawn: current source and tests now cover empty-environment PPID, OLDPWD, and Bash-created bindings. Earlier retry, Ralph recovery, interview reconciliation, ambiguity-integrity, observer, chain-ownership, and generation-focus concerns are also resolved on the current snapshot. The broader preflight executability concern remains modified rather than copied: fresh evidence identifies new bare-cd, unset -f, and Bash de-export gaps.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:838	BLOCKING	Bare POSIX cd is not represented by _DETERMINISTIC_CWD_RE, which requires a directory operand. Consequently _effective_program_root continues resolving verifier programs from workspace_root even though /bin/sh changes to $HOME. Fresh probes demonstrated both unsafe directions: with check.py only under $HOME, cd && python check.py succeeds under /bin/sh but preflight blocks check.py as missing; with check.py only under the workspace, preflight passes but /bin/sh fails after changing to $HOME. Because this gate produces a non-resumable seed_preflight_unexecutable terminal, unmodeled working-directory forms must be treated as inconclusive or resolved according to shell semantics.
2	src/ouroboros/auto/seed_preflight.py:269	BLOCKING	The outer-shell event parser treats every variable-shaped operand of unset as a variable removal and does not honor unset -f. For unset -f HOME; set -u; test -n "$HOME", current preflight reports $HOME unbound, while /bin/sh exits successfully because -f removes a function rather than the variable. The nested-shell parser already distinguishes -f, so the two scope implementations also disagree. This false positive terminally rejects a valid verification command.
3	src/ouroboros/auto/seed_preflight.py:574	BLOCKING	Nested-shell export tracking only adds names and cannot model Bash de-export operations such as export -n HOME or declare +x HOME. A fresh probe using a Bash payload that de-exports HOME before launching sh -c 'set -u; test -n "$HOME"' passed preflight but failed at runtime with HOME: parameter not set. This admits a verification command whose required nested binding is guaranteed to be absent. Either model export-attribute removal or mark later nested-shell binding analysis inconclusive when these Bash forms occur.

Follow-up Findings

#	File:Line	Priority	Confidence	Suggestion
1	/tmp/pr_body_Q00_ouroboros_1944.md:45	Medium	High	Repeat the canonical R-run comparison in an authenticated provider environment; the reported PR run completed zero interview rounds, so throughput parity remains unmeasured.

Test Coverage Notes

• Ran the focused changed-area suites with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest: 470 tests passed across preflight, pipeline retries/deadlines/lateral handling, interview retries, blocked CLI UX, generation focus, attention relay, and subagent behavior.
• Direct /bin/sh comparison probes reproduced all three blocking findings; none is covered by the passing preflight suite.
• The PR body reports broader validation, but its canonical R-run completed zero rounds because the external provider stalled.

Design Notes

The retry, recovery, event, and successor-chain changes fit existing ownership boundaries. The remaining risk is architectural: a partial shell interpreter controls a non-resumable gate, so every authoritative decision must match the production shell or conservatively become inconclusive.

Design / Roadmap Gate

The critical contract is generated Seed verify_command → deterministic preflight → production shell execution. Persistence, retry budgets, Ralph reconciliation, successor ownership, blocked-event delivery, CLI compatibility, and focus projection are adequately supported. The gate fails because working-directory and shell export-state decisions can still disagree with execution in both directions. Since preflight failure records a start-new-session terminal with no normal resume path, these are merge-blocking contract failures rather than optional parser completeness.

Directional Notes

Maintainer memory directed attention toward replay-safe durable state and ambiguity-before-execution. Current source and focused tests provide positive evidence for the recovery work; the blockers rely independently on fresh current-snapshot /bin/sh comparisons at the changed preflight boundary.

Test Coverage

• Ran the focused changed-area suites with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest: 470 tests passed across preflight, pipeline retries/deadlines/lateral handling, interview retries, blocked CLI UX, generation focus, attention relay, and subagent behavior.

Test Coverage Notes

• Ran 293 focused preflight, retry, blocked-UX, attention-relay, and generation-focus tests: all passed.
• Ran 372 additional deadline, lateral, interview-pipeline, scoped-reexecution, subagent, and adapter-chain tests: all passed.
• Fresh production-shell parity probe demonstrated the blocking preflight bypass: cd . || exit 1; python3 missing.py passes preflight but exits 2 under /bin/sh because missing.py is absent.

Design Notes

The retry, persistence, ownership, observability, UX, and focus changes align well with the runtime architecture. The remaining defect is localized to the new shell-preflight interpreter, whose conservative uncertainty currently crosses a command boundary and suppresses a deterministic missing-program result.

Design / Roadmap Gate

The affected critical contract is generated Seed verify_command → deterministic preflight → production /bin/sh execution. Retry budgets, durable interview/Ralph reconciliation, successor ownership, blocked-event delivery, CLI compatibility, and AC-focus projection have positive focused-test evidence. The gate remains unsafe because reachability uncertainty from a preceding || is applied to a verifier after ;, admitting an executable command whose required program is provably absent.

Directional Notes

Review focus followed the ambiguity-before-execution, verification-gate, replay-safe recovery, and observer-truth principles. Maintainer memory and prior rounds were advisory only; the blocker is independently established from the current source snapshot and a fresh /bin/sh comparison.

Prior Findings Status

Prior durability, retry-budget, ambiguity-score, Ralph-resume, EventStore, blocked-UX, and generation-focus concerns are withdrawn based on current source and passing focused tests. The prior shell-parity concern remains but is modified to the two current, independently reproduced cases above. The contributor’s latest assignment-prefix regression covers current-shell expansion but does not cover exporting that prefixed binding into a later nested shell.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:581	BLOCKING	Assignment prefixes on export are recognized for the current shell but not propagated into _nested_shell_scopes, because export-state handling requires segment[0] itself to be export before the prefix is stripped. With FOO absent from the host environment, /bin/sh -c 'FOO=bar export FOO; sh -uc '\''test "$FOO" = bar'\''' succeeds, while preflight emits a blocking unbound_env_var for $FOO. Since seed_preflight is non-resumable, this falsely terminates a valid Seed. Apply assignment prefixes before processing stateful special builtins and add a nested-child parity regression.
2	src/ouroboros/auto/seed_preflight.py:1467	BLOCKING	Program detection does not unwrap the shell negation reserved word !. For verify_command: "! python missing.py", /bin/sh returns status 0 because the missing interpreter operand fails and is then negated, while preflight reports only advisory verify_script_unconfirmed and therefore passes. The production verifier trusts the zero exit status, so a fabricated verification script can reach RUN and satisfy the AC without executing any test. Treat ! as a control prefix while still classifying the following program, with direct /bin/sh regression coverage.

Test Coverage Notes

• Ran all changed-area unit suites covering preflight, pipeline retries/deadlines/lateral behavior, interview recovery, blocked CLI UX, generation focus, attention relay, and subagent prompts: 660 passed in 104.60 seconds.
• Ran Ruff lint and formatting checks over all changed Python files: all checks passed; 29 files already formatted.
• Fresh production-shell probes independently reproduced both blockers: nested prefixed-export execution succeeds while preflight blocks, and negated missing Python verifier execution returns zero while preflight passes.
• The PR’s canonical R-run produced no completed round because the external provider stalled, so no throughput comparison is available.

Design Notes

The recovery, successor ownership, persistence, and observer changes fit the existing architecture. The remaining weakness is the fatal preflight boundary implementing partial shell semantics without conservatively handling two deterministic POSIX forms.

Design / Roadmap Gate

The affected critical contract is generated Seed verify_command → deterministic preflight → production asyncio.create_subprocess_shell verification. A false positive creates a non-resumable terminal for a valid Seed, while a false negative can let a missing verifier produce a successful AC result through shell negation. Retry, durable recovery, successor ownership, event delivery, blocked UX, and focus projection have positive current-head evidence, but the verification boundary is not yet safe.

Directional Notes

Review focus followed ambiguity-before-execution, replay-safe persistence, verification-gate truth, and observer-truth principles. Maintainer memory and prior rounds were used only to target inspection; both blockers are established from the current snapshot and fresh /bin/sh comparisons.

Prior Findings Status

The latest prior concerns about prefixed export propagation and negated verifier classification are addressed in the current source and corresponding tests, so they are withdrawn. The request-changes posture is maintained only for the newly verified POSIX getopts and allexport parity failures.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:256	BLOCKING	The authoritative variable-state analyzer models read bindings but not the POSIX getopts builtin, which assigns its named variable and may assign OPTARG. Consequently, a valid verifier such as set -u; set -- -a; getopts a OPT; test "$OPT" = a exits successfully under production /bin/sh but preflight reports $OPT as unbound_env_var. Because seed_preflight_unexecutable tells the operator to revise the Seed and start a new session, this false positive rejects executable contracts. Model getopts assignments or mark subsequent variable analysis inconclusive, with direct /bin/sh parity tests for both the option variable and OPTARG.
2	src/ouroboros/auto/seed_preflight.py:583	BLOCKING	Nested-shell export-state tracking handles explicit export but ignores POSIX allexport state enabled by set -a or set -o allexport. set -a; FOO=bar; sh -c 'set -u; test "$FOO" = bar' succeeds under production /bin/sh, while preflight reports the nested $FOO as unbound because the assignment updates sequential_values without adding it to sequential_export_names. Track allexport enable/disable state, or conservatively make nested-shell binding analysis inconclusive when it is used, and add direct shell-parity regressions.

Test Coverage Notes

• Ran the focused changed-boundary suites with SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 /root/.local/bin/uv run python -m pytest: 614 tests passed in 105.77 seconds.
• Coverage included Seed preflight/enforcement, transient and interview retries, pipeline deadlines, interview persistence, blocked CLI UX, generation focus, scoped re-execution, attention relay, and subagent prompt behavior.
• Fresh direct comparisons against production /bin/sh reproduced both blocking false positives above; neither case has regression coverage.
• The PR body’s canonical R-run completed zero rounds because the external provider stalled, so throughput impact remains unmeasured.

Design Notes

The retry, persistence, event, ownership, and observer changes are coherently separated and have strong focused-test evidence. The new deterministic shell preflight remains over-authoritative for shell state it does not fully model.

Design / Roadmap Gate

The critical affected boundary is generated Seed verify_command → deterministic preflight → production /bin/sh execution. Retry budgets, interview/Ralph recovery, successor ownership, shared EventStore delivery, blocked UX, and generation focus have positive current evidence. The gate still fails because valid POSIX getopts bindings and allexport propagation are classified differently from execution. Since a false preflight result creates a non-resumable terminal requiring a new session, these are blocking contract failures rather than optional parser completeness.

Directional Notes

Review focus followed ambiguity-before-execution, replay-safe durable recovery, verification-gate truth, and observer clarity. Maintainer memory and prior review summaries were used only to select boundaries for inspection; both blockers were independently reproduced from the current source snapshot against /bin/sh.

@ouroboros-agent please re-review exact HEAD 83df3a0. This keeps the db875a1 shell fixes and makes uv/package-runner parity tests deterministic via failing local shims, avoiding real package-manager cache/daemon hangs that timed out Python CI.

What Improved

• Adds bounded, budget-neutral transient retries for Seed QA, evaluation, lateral repair, and interview backend calls.
• Improves durable interview and Ralph handoff recovery, including resumable deadline-blocked Ralph checkpoints.
• Restores default-mode run → evaluate → evolve chain ownership while retaining complete-product ownership separation.
• Adds shared blocked-event observability, actionable CLI blocked panels, honest ambiguity blocking, and verifier-safe generation focus metadata.

Issue Requirements

Requirement	Status
Deterministically reject fabricated or unbound Seed verification claims before RUN	Partially met — missing programs and many variable/path cases are covered, but valid getopts and allexport commands are falsely rejected.
Remove forced ambiguity_score = 0.19 score gaming and block irreparable ambiguity honestly	Met
Add bounded, budget-neutral retries for Seed QA, evaluator, and lateral transient failures	Met
Add replay-safe bounded interview start/resume/answer retries and closure fallback parity	Met
Make seed_reviewer failures resumable through the REVIEW phase	Met
Enroll default-mode Auto runs in the configured run → evaluate → evolve successor chain without creating a second complete-product owner	Met
Deliver structured blocked events through the shared runtime EventStore and provide actionable CLI recovery guidance	Met
Expose verifier-safe active/frozen AC focus for evolve/Ralph generation observers	Met
Document parallel empirical QA probes whose observed behavior outranks judge scoring	Met
Supply the requested canonical R-run comparison	Partially met — an attempted run and provider-stall mitigation are documented, but no round completed and no performance ratio could be measured; maintainer comments granted an exception.

Prior Findings Status

The latest prior request-changes posture is maintained for the Seed-preflight shell-semantics boundary: the current snapshot independently reproduces valid POSIX getopts and allexport commands being rejected. Earlier concerns around Ralph deadline reconciliation, interview replay safety, retry deadlines, chain ownership, event delivery, blocked UX, and generation-focus truth are withdrawn based on current source inspection and focused passing tests.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:225	BLOCKING	The ordered variable-state interpreter does not model the POSIX getopts builtin, so it falsely marks variables assigned by getopts as unbound. With OPT removed from the environment, unset OPT; set -u; getopts x OPT -x; test "$OPT" = x returns status 0 under the same /bin/sh used by asyncio.create_subprocess_shell, but run_seed_preflight emits blocking unbound_env_var: $OPT. Because this blocker is persisted as seed_preflight_unexecutable and explicitly requires a new session, a valid Seed is terminated before execution. Model deterministic getopts target binding or conservatively make this state flow inconclusive, with direct /bin/sh parity coverage.
2	src/ouroboros/auto/seed_preflight.py:583	BLOCKING	Nested-shell export tracking ignores POSIX allexport state. Assignment-only segments update sequential_values, but set -a / set -o allexport never cause later assignments to enter sequential_export_names. With FOO absent, both unset FOO; set -a; FOO=bar; sh -uc 'test "$FOO" = bar' and the equivalent set -o allexport; ...; set +o allexport execute successfully under /bin/sh, while preflight blocks them as unbound_env_var: $FOO. Track allexport enable/disable state—including the retained export attribute after disabling it—or classify these paths as inconclusive, with production-shell parity regressions.

Test Coverage Notes

• Ran 478 focused tests: 243 Seed-preflight/pipeline-preflight tests, 87 deadline/Ralph/interview/transient/lateral tests, and 148 evolution-focus/attention-relay/subagent/blocked-panel tests; all passed.
• Ran Ruff against the affected runtime modules; all checks passed.
• Added direct current-snapshot comparisons against /bin/sh; both getopts and allexport commands succeeded at runtime but were rejected by preflight.
• No full-suite run was performed. The PR’s canonical provider-backed R-run completed zero rounds because the external provider stalled, so throughput remains unmeasured; maintainer comments explicitly treated that as a performance exception rather than a code blocker.

Design Notes

The retry, persistence, ownership, event, and observer changes have clear boundaries and strong focused coverage. The remaining risk is the deterministic preflight acting as a partial shell interpreter: any authoritative rejection must align with the actual production shell or fail conservatively as inconclusive.

Design / Roadmap Gate

The critical affected contract is generated Seed verify_command → deterministic preflight → production asyncio.create_subprocess_shell execution. Durable retry, Ralph reconciliation, successor ownership, blocked-event delivery, CLI compatibility, and AC-focus projection are adequately supported. The gate fails because POSIX getopts binding and allexport propagation are classified differently from actual execution. Since a false positive creates a non-resumable, start-new-session terminal, these are runtime contract failures rather than optional parser completeness.

Directional Notes

Maintainer memory directed scrutiny toward ambiguity-before-execution and replay-safe durable recovery. Current source and focused tests provide positive evidence for the recovery work; both blockers rely independently on fresh current-snapshot comparisons with the production /bin/sh execution semantics.

Prior Findings Status

Prior blockers involving durable Ralph recovery, interview persistence reconciliation, missing transient retry policy, ambiguity-score rewriting, generation-focus truth, getopts, and allexport have current-source or focused-test evidence of resolution and are withdrawn. The broader verification-gate parity concern remains, but with two new independently reproduced forms rather than previously reported cases.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:239	BLOCKING	_shell_variable_events treats assignment prefixes as persistent only for export, readonly, and Bash declaration builtins, but POSIX assignments preceding other special builtins also persist. With PR1944_FOO absent, /bin/sh -c 'set -u; PR1944_FOO=bar :; test "$PR1944_FOO" = bar' exits 0, while run_seed_preflight emits a blocking unbound_env_var. Because seed_preflight_unexecutable is deliberately non-resumable, this rejects a valid Seed and forces an unnecessary new session. Model the remaining stateful POSIX special builtins, including :, set, shift, times, trap, and unset, or conservatively make unsupported prefix-assignment forms inconclusive.
2	src/ouroboros/auto/seed_preflight.py:1475	BLOCKING	The execution-wrapper unwrapping stops on unrecognized but deterministic wrappers such as nohup, leaving the wrapped path classified only as advisory. In an empty workspace, preflight reports verify_script_unconfirmed and passes ! nohup ./definitely-missing.sh >/dev/null 2>&1; production /bin/sh returns 0 because the missing-program failure is negated. Since the verify gate accepts exit status 0, an AC can be marked successful although its verifier never existed. Recognize deterministic wrappers such as nohup or fail closed/conservatively classify explicit wrapped executable paths before RUN, with a direct negated-command regression.

Test Coverage Notes

• Ran 421 focused tests covering Seed preflight, pipeline preflight/retries/deadlines, interview retries, blocked CLI UX, generation focus, attention relay, and subagent prompting: all passed.
• Ran 246 additional interview-pipeline, lateral, and scoped-reexecution tests: all passed.
• Ruff lint and format checks passed for the changed Python files; the module-size gate passed.
• Fresh /bin/sh parity probes independently reproduced both blocking findings above.
• The PR’s canonical R-run comparison did not complete because the external provider stalled, so throughput evidence remains inconclusive.

Design Notes

The retry, durable-recovery, shared-EventStore, chain-ownership, and observer changes fit existing architectural boundaries. The new shell preflight is correctly placed before RUN, but a blocking static interpreter must either match executor semantics for decidable forms or degrade unsupported forms to inconclusive.

Design / Roadmap Gate

Retry budgets, interview and Ralph replay, successor ownership, blocked-event delivery, CLI compatibility, and AC-focus projection have positive focused-test evidence. The critical Seed verify_command → deterministic preflight → asyncio.create_subprocess_shell boundary remains unsafe in both directions: one valid command becomes a non-resumable false block, while one absent verifier can produce a successful AC result through an unrecognized wrapper plus shell negation.

Directional Notes

Review focus followed ambiguity-before-execution, replay-safe persistence, verification-gate truth, and observer-truth principles. Maintainer memory and prior rounds were used only to select boundaries; both blockers are grounded in the current snapshot and fresh production-shell probes.

Prior Findings Status

The prior REQUEST_CHANGES posture is maintained. Current source independently reproduces two verification-boundary blockers. Earlier Ralph deadline-stranding concerns are withdrawn for this snapshot because pipeline_deadline plus a persisted Ralph checkpoint explicitly recovers to RALPH_HANDOFF, and focused recovery tests pass. Direct getopts, ordinary special-builtin persistence, and simple allexport cases are now covered, but the current composition of special-builtin prefixes with allexport remains incorrect.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:634	BLOCKING	_nested_shell_scopes() only persists assignment prefixes into later exported state for the export builtin. It does not combine the general POSIX special-builtin persistence modeled by _shell_variable_events() with active allexport state. Consequently, the valid production command set -a; FOO=bar :; sh -uc 'test "$FOO" = bar' exits 0 under /bin/sh, but preflight emits blocking unbound_env_var for $FOO. Because seed_preflight is deliberately non-resumable and tells the operator to start a new session, this incorrectly terminates a valid Seed. Persist special-builtin prefix assignments in sequential_values and, when allexport is enabled, sequential_export_names, or conservatively make the nested scope inconclusive; add a direct /bin/sh parity regression.
2	src/ouroboros/auto/seed_preflight.py:1379	BLOCKING	The deterministic wrapper unwrapping omits the shell’s time wrapper. For ! time ./definitely-missing-verifier, /bin/sh attempts the missing verifier and negation converts its failure into exit status 0, while preflight classifies the path only as advisory verify_script_unconfirmed. The production verify gate accepts exit status 0, so an absent verification program can satisfy the AC. Recognize deterministic time forms—including path-qualified /usr/bin/time and their options—or conservatively block the explicit executable operand, with a regression that compares preflight and actual verify-gate behavior.

Follow-up Findings

#	File:Line	Priority	Confidence	Suggestion
1	PR body:42	Medium	High	Repeat the canonical R-run comparison in an authenticated provider environment. The submitted run completed zero rounds because the provider stalled, so it does not establish the retry changes’ throughput impact.

Test Coverage Notes

• Ran 626 changed-area tests covering Seed preflight, pipeline preflight/deadlines/retries, interview retry and recovery, blocked CLI output, generation focus, attention relay, and subagent behavior: all passed.
• Ran 71 additional boundary tests covering adapter successor policy, Ralph polling/handoff recovery, run-evaluate chaining, MCP resume rendering, CLI handoff waiting, and watchdog integration: all passed.
• Ruff lint and formatting checks passed for all changed Python modules.
• Fresh production-shell probes reproduced both blockers: the allexport/special-builtin command exits 0 while preflight blocks it, and negated time returns 0 while the missing verifier remains only advisory.

Design Notes

The retry, durable recovery, evaluation ownership, observability, and projection changes are directionally sound and have strong focused coverage. The Seed preflight has become a large partial shell interpreter, however, so every authoritative blocking decision must match the production shell or explicitly remain inconclusive.

Design / Roadmap Gate

The critical affected contract is generated verify_command → deterministic preflight → production asyncio.create_subprocess_shell verification. Preflight failures receive no repair and are not resumable, making false positives destructive to valid sessions. Conversely, a false negative combined with shell negation can let an absent verifier return success and satisfy an AC. Persistence, deadline replay, compatibility, retry budgets, successor ownership, event delivery, blocked UX, and focus projection have positive current-head evidence, but the verification boundary remains unsafe in both directions.

Directional Notes

Review focus followed ambiguity-before-execution, replay-safe durable state, verification-gate truth, and observer clarity. Maintainer memory was used only to prioritize the Ralph checkpoint and Seed verification boundaries; both reported blockers are established independently from current source and fresh /bin/sh probes.

Prior Findings Status

The prior classification standard is maintained: deterministic preflight decisions must agree with the production shell because both non-resumable false blocking and unsafe admission are execution-contract failures. The latest snapshot addresses the previously discussed getopts, allexport special-builtin prefix, and time wrapper cases with passing regressions. Those exact concerns are not re-raised. Fresh inspection found two adjacent, independently reproduced nested-shell parity failures that remain under the same verification-boundary standard.

Test Coverage Notes

• Results: 529 auto/preflight/runtime tests passed, 148 CLI/MCP/evolution tests passed, and 79 state/adapter/chain tests passed.
• Direct current-source probes against production /bin/sh independently reproduced both blocking divergences; neither multiline nested-shell segmentation nor skipped conditional-export propagation has focused regression coverage.

Design Notes

The decomposition into preflight enforcement, retry/recovery helpers, terminal event projection, and focus projection is directionally sound. The remaining problem is that the new deterministic shell interpreter is an admission-control authority but still models command boundaries and conditional state less conservatively than the actual executor.

Design / Roadmap Gate

The critical affected boundary is generated Seed verify_command → deterministic preflight → production asyncio.create_subprocess_shell//bin/sh execution. Preflight failure is non-resumable and requires a new session, while preflight admission allows the command to become verification evidence. Newline command separation and conditional execution must therefore preserve the same environment-state semantics as the production shell or fail conservatively as inconclusive. The durable retry, persistence, replay, compatibility, observer, and successor-ownership boundaries otherwise have positive focused-test evidence.

Directional Notes

Advisory maintainer memory focused inspection on ambiguity-before-execution, replay-safe durable state, and truthful verification gates. Current source and focused tests provide positive evidence for retry, interview/Ralph recovery, successor ownership, EventStore delivery, blocked UX, and AC-focus behavior. The blockers rely only on fresh current-snapshot probes against /bin/sh.

• Adds substantial focused regression coverage for retries, preflight, blocked UX, EventStore delivery, and scoped evolution.

Issue Requirements

Requirement	Status
Vision #1157: recoverable transient failures receive bounded retry instead of immediately ending BLOCKED	Partially met — the new transient retry paths are covered, but expired Ralph checkpoints are presented as recoverable and then crash or re-block.
Deterministically reject fabricated Seed verification claims before RUN	Not met — a guaranteed conditional branch can execute a missing verifier under shell negation while preflight passes.
Do not reject executable verification commands through incorrect shell-state modeling	Not met — set -a with readonly, read, or getopts produces false non-resumable blocks.
Remove the forced ambiguity_score = 0.19 downgrade	Met.

Include answer-sheet-safe AC focus in generation-started events	Met.
Document parallel empirical QA probes that outrank judge-only scoring	Met.

Prior Findings Status

Earlier exact shell forms discussed by the contributor appear to have received targeted fixes, so those specific cases are not repeated as established blockers. The verification-parity classification remains applicable because fresh current-snapshot commands still diverge in both directions. The prior favorable assessment of Ralph deadline recovery is modified: direct current-head execution proves that the advertised resumable checkpoint crashes before reconciliation.

After the gate admits a BLOCKED pipeline_deadline state with ralph_job_id, line 621 evaluates self.ralph_resumer; AutoPipeline has no such field or method and is slotted, so the resume raises AttributeError: 'AutoPipeline' object has no attribute 'ralph_resumer'. Even if that dereference were supplied, _run_execution_phase() at line 1215 unconditionally enforces the already-expired deadline and blocks again before reconciliation. The added test only calls _result() and verifies the displayed capability; it never invokes resume. Restore a real persisted-job reconciliation path and add an end-to-end expired-deadline → run() resume test proving terminal reconciliation rather than projection alone.

Test Coverage Notes

• Passed 266 Seed-preflight/pipeline-preflight tests.
• Passed 271 retry, deadline, lateral, and interview-pipeline tests.
• Passed 148 blocked-panel, attention-relay, evolution-focus, scoped-reexecution, and subagent tests.
• Passed 70 adjacent Ralph-handoff/state tests.
• Fresh /bin/sh parity probes reproduced both preflight blockers.
• A real expired-deadline Ralph checkpoint resume reproduced the unhandled AttributeError; current deadline coverage verifies only result/event projection, not AutoPipeline.run() recovery.

Design Notes

The retry, observer, UX, and successor-chain changes generally align with the intended architecture. The gate fails at two infrastructure-critical contracts: durable state must not advertise an unusable resume transition, and deterministic verification admission must preserve production-shell semantics whenever it makes a blocking or authoritative decision.

Design / Roadmap Gate

The affected boundaries are persisted RALPH_HANDOFF checkpoint → deadline BLOCKED state → --resume reconciliation, and generated Seed verify_command → non-resumable preflight decision → production /bin/sh verification. The first boundary exposes a resume capability without an executable reconciliation implementation. The second is unsafe in both directions: valid commands can be destructively rejected, while a missing verifier can be admitted as successful evidence. Retry budgets, EventStore sharing, compatibility surfaces, blocked rendering, successor ownership, and generation-focus projection otherwise have positive focused-test evidence.

Directional Notes

Review focus followed the advisory ambiguity-before-execution, replay-safe durable-state, and truthful-verification-gate priors. All blockers are independently grounded in the current source snapshot and fresh runtime probes; maintainer memory was used only to select the boundaries to inspect.

Test Coverage

• Passed 266 Seed-preflight/pipeline-preflight tests.
• Passed 271 retry, deadline, lateral, and interview-pipeline tests.
• Passed 148 blocked-panel, attention-relay, evolution-focus, scoped-reexecution, and subagent tests.
• Passed 70 adjacent Ralph-handoff/state tests.
• Fresh /bin/sh parity probes reproduced both preflight blockers.
• A real expired-deadline Ralph checkpoint resume reproduced the unhandled AttributeError; current deadline coverage verifies only result/event projection, not AutoPipeline.run() recovery.

Merge Recommendation

Request changes. Preserve the substantial retry, observability, chain-parity, UX, and generation-focus improvements, but implement and directly test truthful expired-deadline Ralph reconciliation, and align the two reproduced shell-state/control-flow cases with production /bin/sh before merge.

[Q00]

Ready for exact-HEAD re-review at 6ba38fea1.

Resolved the latest blockers:

• added a real persisted Ralph job poll/reconciliation path before expired-deadline gates, wired through the MCP composition root, with an end-to-end expired deadline → AutoPipeline.run() → COMPLETE regression
• aligned guaranteed else branch program detection under negation
• modeled set -a bindings created by readonly, read, and getopts, with direct /bin/sh parity tests

Validation: 341 affected tests passed; module-size gate passed; Ruff lint/format passed; targeted mypy passed; git diff --check clean.

What Improved

• Adds deterministic Seed preflight before RUN, preventing many fabricated dependency, path, and environment claims.
• Adds bounded, budget-neutral retries for transient QA, evaluator, lateral, and interview backend failures.
• Improves default-mode run→evaluate→evolve ownership, durable Ralph checkpoint reconciliation, shared EventStore delivery, blocked-session UX, and generation AC-focus observability.

Issue Requirements

Requirement	Status
Prevent fabricated verify scripts, missing verifier programs, unbound variables, and conceptual paths from reaching RUN	Partially met — the new gate covers the reviewed forms but admits missing programs behind unrecognized deterministic wrappers
Remove Seed QA ambiguity-score gaming and block unrepairable ambiguity honestly	Met
Retry transient Seed QA, evaluator, and lateral failures without consuming bounded repair/persona budgets	Met
Retry transient interview start/resume/answer failures without discarding the interview budget	Met
Make pre-run seed-review failures resumable	Met
Restore default-mode run→evaluate→evolve chain parity while preserving complete-product ownership boundaries	Met
Deliver blocked Seed/session events through the shared runtime EventStore and avoid emission livelock	Met
Provide actionable CLI blocked output, including non-resumable next steps	Met
Expose AC-focused generation events without leaking verification answer-sheet details	Met
Update QA/Ralph/auto host guidance for the new retry and blocked-session behavior	Met
Provide a trustworthy canonical R-run comparison	Partially met — the body reports a provider-stall comparison and explicitly defers a measurable throughput conclusion

Prior Findings Status

The prior Ralph deadline/resume, interview retry persistence, interpreter detection, shell-state propagation, control-flow, directory-resolution, and special-builtin concerns are addressed or withdrawn based on current source and focused tests. The verification-program concern remains modified rather than repeated verbatim: current support covers the previously reported forms, but the fresh deterministic-wrapper cases above remain.

Blockers

#	File:Line	Severity	Finding
1	src/ouroboros/auto/seed_preflight.py:1436	BLOCKING	_command_program_tokens() recognizes only a bounded wrapper list (env, timeout, uv, package runners, nice, nohup, time, command, and exec). Deterministic wrappers such as setsid and stdbuf are left unclassified, so ! setsid ./missing_verify and ! stdbuf -oL ./missing_verify produce only the non-blocking verify_script_unconfirmed finding and let run_seed_preflight() pass. In the production /bin/sh, both commands return success when the missing verifier is negated, allowing absent verification programs to become successful evidence. This violates the PR’s stated contract that verifier files neither existing nor declared as artifacts are blocked; classify these wrappers or conservatively block explicit executable operands, with direct /bin/sh parity regressions.

Test Coverage Notes

• Focused preflight, pipeline deadline, transient-retry, interview, CLI, attention-relay, evolution, and subagent suites passed in the available environment; individual runs reported 295, 200, 148, and 196 passing tests.
• Ruff passed for all changed Python production files.
• Fresh /bin/sh probes reproduced the remaining setsid/stdbuf preflight false-negative; no full-suite run was required to establish this blocker.

Design Notes

The retry, persistence, observer, and successor-chain changes fit the existing ownership model. The deterministic preflight interpreter is the critical boundary, and its conservative classification is incomplete for common process wrappers.

Design / Roadmap Gate

The affected contract is generated Seed verify_command → deterministic preflight → production asyncio.create_subprocess_shell//bin/sh verification. Preflight failure is non-resumable, while admission allows the command to supply acceptance evidence, so false negatives are merge-blocking. The current wrapper list must either cover the supported execution surface or fail closed for ambiguous explicit executable operands.

Directional Notes

Review focus followed the advisory replay-safe durable-state and truthful-verification-gate priors. Current source and fresh shell probes, not prior memory, establish the blocker. The PR’s own notes and prior rounds indicate the Ralph and interview durability paths were materially revised; those concerns were rechecked and not re-raised.

Test Coverage

• Focused preflight, pipeline deadline, transient-retry, interview, CLI, attention-relay, evolution, and subagent suites passed in the available environment; individual runs reported 295, 200, 148, and 196 passing tests.
• Ruff passed for all changed Python production files.
• Fresh /bin/sh probes reproduced the remaining setsid/stdbuf preflight false-negative; no full-suite run was required to establish this blocker.

Merge Recommendation

Request changes. The substantial retry, durability, chain-parity, observability, UX, and focus improvements are supported by focused tests, but the preflight gate can still admit an absent verifier through setsid or stdbuf plus shell negation. Add wrapper classification or conservative rejection and direct shell-parity regressions before merge.
