Summary

  • add the strict shared request/result/authority contracts for open-world provisional publication
  • keep provisional publication separate from the existing GEPA publication protocol
  • seal authority and full-snapshot validation against subclasses and permissive coercions
  • expose the storage surface needed by the enterprise atomic publisher

Behavior

An accepted open-world candidate can be represented as a content-only provisional successor with an exact qualification-authority reference. Shared code defines the contract only; enterprise storage remains responsible for transactional publication, proof binding, governance, retention, aggregation exclusion, and billing non-effect.

Testing

  • Phase 4 exact-head gate: PASS (12/12)
  • Phase 1 matrix: 597 passed, 9 skipped
  • Phase 2 evidence: 826 passed, 9 skipped
  • Phase 3 analysis: 1,718 passed, 9 skipped
  • Phase 4 publication inventory: 280 passed
  • Ruff: clean
  • Pyright: 0 errors, 0 warnings

Stack

Summary by CodeRabbit

  • New Features

    • Added support for provisional playbook publications using open-world optimization.

📝 Walkthrough

Walkthrough

The change adds open-world deployment lifecycle states, separates legacy and decision-proof optimizer validation, defines provisional publication request and result contracts, and adds provisional publication storage operations with contract tests.

Changes

Open-world optimizer boundaries

Layer / File(s) Summary
Optimizer boundaries and lifecycle types
reflexio/models/api_schema/domain/entities.py, reflexio/server/services/playbook/publication.py, tests/server/services/playbook/test_publication_models.py
The API exports five open-world lifecycle states. Decision proofs accept offline_tuner_open_world, while ordinary publication requests continue to reject it. Tests cover optimizer literals, lifecycle states, UserPlaybook field partitions, and legacy request rejection.

Provisional publication contracts

Layer / File(s) Summary
Provisional request and result contracts
reflexio/server/services/playbook/publication.py, tests/server/services/playbook/test_provisional_publication_contract.py
The new models validate authority references, canonical incumbent snapshots, candidate and proof bindings, subject epochs, digests, optimizer restrictions, and terminal outcome fields. Tests cover valid and invalid bindings, exact subcontract types, scalar serialization, fingerprint drift, and result-state combinations.

Provisional publication storage contract

Layer / File(s) Summary
Provisional publication storage contract
reflexio/server/services/playbook/publication.py, reflexio/server/services/storage/storage_base/playbook/_user.py, tests/server/services/playbook/test_provisional_publication_contract.py
The provisional store protocol and user playbook mixin define claim, stage, commit, and terminal-result loading operations. Tests verify separation from the legacy store and required claim parameters.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 8bc17

This change adds a provisional publication contract while keeping durable proof binding in the enterprise publisher. The remaining merge-readiness concern is that subject-epoch validation is duplicated across publication paths and could drift, so the PR is mergeable with explicit owner follow-up.

458-483: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extract the duplicated subject-epoch validation.

Lines 458-483 repeat PublicationRequest.__post_init__ lines 310-335 exactly. Both contracts feed the same subject_epochs_json wire shape to storage. If one copy changes later, the two publication paths accept different epoch payloads. Extract one module-level helper and call it from both contracts.

♻️ Proposed refactor
+def _validate_subject_epochs(value: str) -> None:
+    epochs = _canonical_payload("subject_epochs_json", value)
+    if (
+        not isinstance(epochs, dict)
+        or set(epochs) != {"subjects"}
+        or not isinstance(epochs.get("subjects"), list)
+        or not epochs["subjects"]
+    ):
+        raise ValueError("subject epochs must contain a non-empty subjects list")
+    subject_refs: set[str] = set()
+    for item in epochs["subjects"]:
+        if not isinstance(item, dict):
+            raise ValueError("subject epochs must contain objects")
+        if set(item) != {"ref", "epoch"}:
+            raise ValueError("subject epochs must use ref and epoch fields")
+        subject_ref = item["ref"]
+        epoch = item["epoch"]
+        if (
+            not isinstance(subject_ref, str)
+            or not subject_ref
+            or type(epoch) is not int
+            or epoch < 0
+        ):
+            raise ValueError("subject epochs contain an invalid identity or epoch")
+        if subject_ref in subject_refs:
+            raise ValueError("subject epochs must contain unique subject refs")
+        subject_refs.add(subject_ref)

Then replace both inline blocks with _validate_subject_epochs(self.subject_epochs_json). The error messages stay identical, so the existing tests keep passing.

Derive the digest field list from the dataclass fields.

The tuple of nine field names duplicates the dataclass declaration. If a future digest field is added to QualificationAuthorityRef and not added to this tuple, the new field skips digest validation silently. Use dataclasses.fields and exclude epoch instead.

     def __post_init__(self) -> None:
         if type(self.epoch) is not int or self.epoch <= 0:

This needs from dataclasses import dataclass, fields at the top of the file.

CodeRabbit dispositions:

  • Duplicated subject-epoch validation: fixed in 8bc177dd by extracting one private helper used by both request contracts. Validation order, rules, messages, and public API are unchanged.
  • Derive authority digest fields from dataclasses.fields: intentionally not applied. The explicit tuple is a closed-schema allowlist; auto-validating every future non-epoch field as a digest would incorrectly constrain future non-digest metadata and silently broaden validation. Current digest fields remain parametrically covered.

Fresh per-task review: CLEAN. Focused verification: 57 tests passed, Ruff clean, Pyright 0 errors.

@yilu331, understood. The explicit authority-digest tuple is a closed-schema allowlist. A new review will assess the current PR state.

Timestamp: 2026-08-22T02:29:10.947Z
Learning: In `reflexio/server/services/playbook/publication.py`, the explicit tuple of qualification-authority digest fields is a closed-schema allowlist. Do not derive the fields from `dataclasses.fields`, because future non-`epoch` authority metadata might not be a digest and automatic derivation would silently broaden validation.

@yilu331, understood.

The shared helper in 8bc177dd addresses the duplicated subject-epoch validation. The explicit authority-digest tuple remains a closed-schema allowlist. The reported focused verification is clean.

Keep SQLite terminal stage membership aligned with the optimizer-family matrix and cover every stage/outcome combination.
Exercise malformed stages, outcomes, and inactive optimizer kinds while proving rejected writes leave SQLite jobs unchanged.
Add the shared strict qualification-result record and its immutable
tenant-local SQLite cache, keyed by (component_identity_digest,
suite_digest).

The record pins the exact v1 schema version, all seven safety-critical
class counts in canonical order (nonnegative, passed_required never
above required), SHA-256 component/suite/result digests, and sorted,
unique observation digests. It carries no customer data or model output.

Persistence is idempotent for a semantically exact replay and rejects a
semantic conflict with OpenWorldQualificationConflictError; the first
insert controls created_at, which is excluded from conflict equality.
Database triggers reject raw UPDATE and DELETE so a cached qualification
cannot be edited out from under an attempt.
…ters, upgrade

Add strict=True to OpenWorldQualificationClassCount/Record so bool-as-int,
int-as-bool, numeric strings, and floats are rejected instead of silently
coerced. Add independent-connection concurrent-writer tests (identical
writes converge, conflicting writes yield one winner + N-1 typed conflicts
+ one intact row) and an upgrade test proving normal SQLiteStorage init
reinstalls the qualification table and both immutability triggers on a
pre-Task-9 database, leaving unrelated data intact.
Reject qualification records whose aggregate passed flag disagrees with the canonical per-class required counts, keeping shared SQLite reads aligned with PostgreSQL.
Allow qualification reducers to report population failure when every per-class count passes, while retaining the one-way pass-all invariant. Permit the approved open-world failed outcomes without changing abstained transitions.
