Summary

Implement the Assay experiment runner and close the review findings, with the
primary agent integrating and independently reviewing delegated work.

  • Immutable subjects, snapshots, authorization plans, and durable object store.
  • Complete typed execution/evaluation failure paths, live adapter configuration
    binding, bounded scheduling, cancellation cleanup, and recoverable persistence
    failure manifests.
  • Run-scoped PAA evidence and operating records with explicit cost coverage.
  • Offline pinned-schema, provenance, coordinate, closure, and completeness
    verification; exact export and reproducible report reconstruction.
  • Seeded paired scalar bootstrap, ordinal sign and classification correctness
    tests, fixed reporting threshold, explicit improvement direction, declared
    Holm family, duplicate rejection, and subject drift protection.
  • Local consistency materializer/evaluator and synthetic full-pipeline acceptance.
  • Packaged JSON schemas, CLI, public immutable dependency pins, and Python
    3.12/3.13 CI.

Prerequisites

Dependencies point at these exact reviewed commits, not sibling directories or
moving branch tips. Merge upstream PRs first; pins remain reproducible.

Validation

  • Assay Ruff and strict source mypy pass.
  • 75 tests pass in the isolated Python 3.13 install. Tests exercise failure,
    drift, accounting, malformed schema/records,
    omitted failed-worker skips, bundle insertion, report recomputation, and CLI.
  • Source distribution and wheel build; wheel includes schemas and py.typed.
  • Source distribution installed using Python 3.13 and a fresh dependency cache,
    downloading public Git-pinned dependencies without sibling checkouts.
  • Jig: 1,173 tests. PAA: 766 runtime/conformance + 89 package tests.

Explicit boundaries

Acceptance uses a synthetic coding worker, not a paid or production experiment.
Callers supply production repository/task adapters and ambiguity judges. Jig's
included adapter consumes explicitly materialized prompt strings and requires
stable resource configuration. Preparation stages and component-level operating
cost aggregation are rejected, not silently approximated. Offline verification
is relative to the supplied plan and does not attest producer identity or prove
that unrecorded real-world attempts never occurred.

Existing ignored comms/ design notes and unrelated Jig local files remain
untouched/unpublished. See docs/remediation-plan.md and README for details.

Summary by CodeRabbit

  • New Features

Merge Risk: 🟡 Moderate · up to 8c34b

The new canonical-reference handling is ready, but unresolved execution, report, schema, and durability issues can still produce unavailable runs or unreliable offline results. Resolve or explicitly accept these risks before merge.

src/assay/investigations/consistency.py (1)

114-124: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Nested call sites can still receive an automatic verdict.

The module docstring states that indirection needs the configured judge. ast.walk(function) collects calls from the full subtree of the single return statement. A source such as def implement(value): return (lambda v: normalize_name(v))(value) satisfies straight and sets helper_used, so it is classified as reused without adjudication. Restrict the automatic path to calls in the return expression, or state this limit in the docstring.

src/assay/models.py (1)

51-52: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Consider deep-freezing the dict payloads.

frozen=True blocks attribute rebinding only. The worker, intervention, and conditions dicts stay mutable, and worker_identity returns the caller's dict object unchanged. A caller that keeps a reference can mutate an Arm after it is hashed and stored, so the stored content address no longer matches the in-memory object.

A copy in the validator, or a frozen mapping type, restores the immutability guarantee. The same pattern applies to EvaluatorDeclaration.configuration and StudySnapshot.pricing_assumptions.

Move the assay.execution import behind TYPE_CHECKING.

EvaluationResult and WorkerResult appear only in return annotations, and from __future__ import annotations defers their evaluation. src/assay/execution.py does not import assay.protocols, so this is an unnecessary runtime dependency rather than an existing import cycle.

Use the package version instead of the literal "0.1.0".

build_report rejects any config whose engine_version differs from assay.__version__ (src/assay/report_engine.py Lines 98-99). This literal breaks the test at the next version bump. tests/test_consistency.py imports __version__ for the same field.

both schemas: schemas/assay-evaluation-failure.schema.json (lines 51-55) and
schemas/assay-execution-outcome.schema.json (lines 57-61). Keep the existing
schema_version definitions unchanged.

In `@schemas/assay-execution-outcome.schema.json`:
- Around line 66-72: Update the schema’s status-dependent validation by adding
JSON Schema if/then conditions: when status is “succeeded”, require non-null
output_ref; when status is “failed”, require non-null error_type and
error_message and disallow non-null output_ref. Preserve the existing status
enum and property definitions.

In `@schemas/assay-execution-plan.schema.json`:
- Around line 213-221: Update the arm_cost_estimates object schema to set
additionalProperties to false, ensuring every key must match its existing
identifier pattern and use the PriceEstimate definition; if this schema is
generated, make the corresponding change in its generator.

In `@src/assay/adapters/jig.py`:
- Line 78: Update JigWorker.run around the run_agent call to enforce a mandatory
positive adapter-level timeout for each attempt, allowing TimeoutError to
propagate for run_cell to convert into a durable WorkerFailure. Also include the
same timeout_s value in configuration() so the deadline is authorized with the
arm.

In `@src/assay/canonical.py`:
- Around line 16-17: Update _validate to reject strings containing invalid or
unpaired Unicode surrogates by validating their UTF-8 encodability, and ensure
canonical_json exposes the established CanonicalizationError rather than leaking
UnicodeEncodeError. Preserve validation for valid strings and existing handling
for None, booleans, and integers.

In `@src/assay/models.py`:
- Around line 260-261: Update the failed-outcome validation in ExecutionOutcome
so an empty error_message is rejected the same way as an empty error_type.
Preserve the existing checks that failed outcomes have no output and include
both required error fields.

In `@src/assay/report_engine.py`:
- Around line 383-385: Update the group amount accumulation near totals and
group["amounts"] to retain Decimal values instead of converting each increment
to float; initialize missing amounts as Decimal and add amount directly. Convert
accumulated group totals to floats only when constructing by_stage_arm,
preserving Decimal precision throughout aggregation.

In `@src/assay/reporting.py`:
- Around line 136-141: Update the Holm adjustment flow around numeric and
adjusted_values so _holm receives only non-None p-values from interim, excluding
descriptive-only comparisons. Preserve result ordering and assign adjusted
values back only to comparisons with a p_value, leaving untested comparisons’
adjusted value as None.

In `@src/assay/store.py`:
- Line 49: Replace the recursive mkdir call in the target directory creation
flow with one-level-at-a-time directory creation, and fsync each directory’s
parent immediately after creating its entry. Preserve existing-directory
handling and ensure the complete hierarchy is durable before publishing the
object.

In `@src/assay/verify.py`:
- Around line 400-408: Update verify_bundle to scan the entire bundle root
rather than only store.objects, rejecting unexpected files such as root-level
notes.json while preserving valid object-entry validation. Refine the
bundle_closure mismatch handling so missing objects report a missing-objects
message, while extra-object mismatches retain an extra-objects message.

Require schema_version in both persisted-record schemas.

A missing schema_version passes JSON Schema because default does not insert properties. The offline verifier then rejects execution records and does not recognize evaluation-failure records as failure records.

Add "schema_version" to required in both schemas:

Enforce the invariant selected by status.

When status is "succeeded", require a non-null output_ref. When status is "failed", require non-null error_type and error_message, and reject a non-null output_ref. Add JSON Schema if/then conditions for these rules.

Close arm_cost_estimates to non-matching keys.

patternProperties does not reject unmatched keys. ExecutionPlan.arm_cost_estimates uses dict[Identifier, PriceEstimate], so _bad arm is rejected by the model but accepted by this schema without validating its value. Add additionalProperties: false. If the schema is generated, update the generator.

Add a mandatory per-attempt deadline to run_agent.

JigWorker.run awaits run_agent without a deadline. AgentConfig.soft_deadline_s only limits new tool turns; it does not bound an in-flight provider call. A stalled call holds an execute_plan dispatch slot and can prevent manifest persistence when all slots are occupied.

Use a positive adapter-level deadline. run_cell will convert TimeoutError into a durable WorkerFailure.

Convert invalid Unicode into CanonicalizationError.

_validate accepts unpaired Unicode surrogates. The later UTF-8 encoding then raises UnicodeEncodeError. This bypasses the public canonicalization error type for input such as json.loads('"\\ud800"').

Reject an empty error_message on failed outcomes.

The guard treats error_type and error_message differently. not self.error_type rejects an empty string, but self.error_message is None accepts one. A failed ExecutionOutcome can then be recorded with error_message="", which defeats the typed failure record.

Keep a Decimal accumulator for each stage/arm.

Accounting accepts any finite non-negative float. For one group with 1e16, 1.0, and 1.0, the repeated round-trip produces 1e16, while the Decimal total produces 1.0000000000000002e16. Store group totals as Decimal and convert them only when building by_stage_arm; report verification recomputes the same path and will not detect this mismatch.

Exclude untested comparisons from the Holm family.

Line 136 substitutes 1.0 for every comparison that did not reach the n >= 10 gate, then passes the padded list to _holm. The placeholders increase total inside _holm, so each tested comparison gets the multiplier (n_all - rank) instead of (n_tested - rank).

Example: one tested candidate with p_value = 0.03 and two descriptive-only candidates produce adjusted = 0.09 instead of 0.03. The decision at Line 144 then reports no_detected_difference instead of different.

Untested hypotheses are not members of the multiplicity family. Correct the family to the comparisons that produced a p-value.

Persist each newly created directory level.

When mkdir(parents=True) creates .assay, objects, or sha256, the later fsync on target.parent does not persist the new entries in their parent directories. Create directories one level at a time and fsync each parent after adding a directory entry. Otherwise, a power loss can remove the directory hierarchy and the published object.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Set an upper bound for bootstrap_samples.

bootstrap_paired() allocates samples observed sums and performs samples * n draws for each stream. The report configuration permits an arbitrarily large integer. A small untrusted bundle can therefore exhaust memory or CPU during offline verification.

Enforce one protocol-wide maximum in StatisticalProfile, its JSON schema, and this runtime boundary.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Perform exact subtraction before paired inference. Both report paths can convert valid finite endpoint values into an infinite binary64 delta before the exact arithmetic begins.

  • src/assay/reporting.py#L142-L146: construct each candidate-minus-reference difference from exact binary64 ratios.
  • src/assay/report_engine.py#L253-L253: use the same exact difference representation before calling the shared inference functions.

Review details

Suppressed comments (2)

src/assay/models.py:24

  • frozen=True only prevents reassignment of model attributes; the nested dictionaries in Arm, EvaluatorDeclaration, StudySnapshot, and related models remain writable. For example, snapshot.arms[0].worker["version"] = ... succeeds after a plan is compiled, so the public snapshot/plan objects are not actually immutable as this contract requires. Use deeply immutable nested values or freeze/defensively copy them at model boundaries.
class WireModel(BaseModel):
    model_config = ConfigDict(extra="forbid", frozen=True, allow_inf_nan=False)

src/assay/verify.py:57

  • _references treats every string beginning with sha256: as an object edge, but free-form values such as Subject.label and task text are not constrained to exclude that prefix. A legitimate label, category, or description equal to a hash-looking string is consequently treated as a missing object and causes snapshot/manifest verification to fail. Restrict closure traversal to schema-declared reference fields or reserve and validate this prefix consistently.

Implemented the approved latest-round fixes in ed5ac80 (Harden artifact lineage and governed run verification).

Addressed

  • Evidence verification now requires content-addressed sources and the authoritative execution/task/worker-configuration/evaluator-basis/declared-detail lineage. Regression tests rehash dependent records so stale hashes cannot mask a semantic failure.
  • Known input/output/trace/detail artifacts must decode as canonical JSON. Invalid realization inputs fail preflight before execution.
  • Cross-run reports require compatible task/scope/contracts, selected declarations, repeat and scheduling settings, runtime versions, and pricing context. Compatible population shards and complementary exclusions remain supported.
  • Recoverable accounting-write failures list missing operating coordinates explicitly. Consistent partial manifests report incomplete_run without contradictory completeness errors; they remain ineligible for complete-run reporting/export.
  • CLI export handles ObjectIntegrityError as export_failed.
  • Governed JSON mappings and arrays are recursively owned and read-only, including copied model updates; serialized model dumps remain detached and mutable.
  • Bootstrap samples are bounded to 100–100,000 consistently in the model, generated schema, and statistical entry points. This bounds replicate allocation, not total verification CPU across arbitrarily large studies.
  • Schema checking, construction, and resolution share a draft-07 default while honoring explicitly declared supported dialects. Schema-edge discovery uses the resolver's dialect-aware subresource rules.
  • README now includes uv installation; remediation documentation names paired-v2.
  • Closure traversal follows field-assigned artifact roles instead of arbitrary hash-looking strings. Extension JSON declares dependencies through the reserved assay_object_refs array. Shared object bytes are tracked separately per traversal role. The convention and migration implications are documented in docs/object-references.md.

Validation

  • Python 3.12: 151 tests passed (61 new regression cases).
  • Python 3.13: 149 tests passed, plus the two final schema-keyword regression cases passed separately.
  • Ruff, mypy (21 source files), generated-schema drift check, and git diff --check passed.
  • Wheel and source distribution built successfully; wheel includes the new modules and seven published schemas.

Intentionally outstanding

  • Exact endpoint subtraction (triage item 11) remains open and unchanged. Overflow requires extreme opposite-sign endpoints; bounded experiment scores are not exposed to this failure. Current behavior fails reporting rather than verifying a silently incorrect result. The recommended small follow-up is an explicit out-of-range-delta error while retaining paired-v2; exact endpoint arithmetic would need a separately versioned profile and a policy for final effects/intervals outside binary64 range. That follow-up has not been approved or implemented.
  • The optional schema-test refactor (item 13) was not applied.
  • Assay's Jig/PAA dependency pins remain unchanged; the upstream PRs have merged, but this commit does not update their revisions.
  • This summary covers the approved latest round, not closure of every finding from earlier rounds. No review threads have been automatically resolved.
