Scope

This PR adds shared vocabulary and compatibility foundations only. It does not compose or run the enterprise offline tuner, publish candidates, or add online observation.

Test Plan

  • Exact-head focused shared and enterprise remediation gate: 276 tests passed.
  • Enterprise Phase 3 gate consuming this exact shared commit: 1602 passed, 14 expected skips.
  • Enterprise Phase 2 regression gate: 790 passed, 14 expected skips.
  • Scoped Ruff, format, and Pyright checks passed.

Summary by CodeRabbit

  • New Features

    • Added discovery and held-out analysis stages to optimization workflows.
    • Added outcomes for missing hypotheses, analyst qualification, failed evidence, stale incumbents, governance invalidation, and infrastructure failures.
    • Added discovery memos, candidates, attempt decisions, and immutable qualification records.
    • Exposed provider request guard errors through the public interface.
  • Bug Fixes

    • Improved optimizer-specific workflow transitions and terminal outcome validation.

📝 Walkthrough

Walkthrough

The change adds open-world optimization stages, outcomes, artifacts, and qualification records. SQLite supports optimizer-specific lifecycle transitions and immutable qualification caching. The change also exports ProviderRequestGuardError through the LLM public surfaces.

Changes

Open-world optimization lifecycle

Layer / File(s) Summary
Optimization identities and SQLite contracts
reflexio/models/api_schema/domain/entities.py, reflexio/server/services/storage/sqlite_storage/_base.py
Adds open-world stages, terminal outcomes, artifact kinds, and SQLite migration and fresh-install constraints.
Optimizer-specific transition rules
reflexio/server/services/storage/sqlite_storage/playbook/_optimization.py, reflexio/server/services/storage/storage_base/playbook/_optimization.py, tests/server/services/storage/..., tests/models/test_open_world_optimization_identity.py
Applies optimizer-specific stage and terminal-outcome rules. Tests cover valid transitions, invalid requests, lease fencing, settled jobs, migrations, and artifact round trips.
Qualification record contract and cache
reflexio/models/api_schema/domain/entities.py, reflexio/server/services/storage/..., tests/models/test_open_world_qualification_record.py, tests/server/services/storage/sqlite_storage/test_open_world_qualification_cache.py
Adds strict immutable qualification models and SQLite persistence keyed by component and suite digests. Tests cover validation, idempotent writes, conflicts, concurrency, upgrades, and immutable storage.

LLM error export surface

Layer / File(s) Summary
ProviderRequestGuardError public export
reflexio/server/llm/__init__.py, reflexio/server/llm/litellm_client.py, tests/server/llm/test_litellm_client_surface.py
Exports ProviderRequestGuardError from the LiteLLM client and LLM package. Tests verify the public export identity.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to bcc49

This change adds open-world analysis states and persistence compatibility, but a held-out analysis path may still bypass replay evaluation, which could allow qualification decisions without the intended validation. The PR should not merge until that behavior is fixed or explicitly accepted by the owner.

1103-1192: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff

Optional: expose matrix cases as parameters instead of nested loops.

The nested loops build roughly 600 cases inside one test function. A failure stops the whole matrix at the first bad cell and reports no case identifier. Precomputing the cases into a list and passing them to pytest.mark.parametrize gives one test per cell, readable ids, and full-matrix results on failure. The same pattern applies to test_invalid_stage_inputs_leave_sqlite_job_unchanged and test_optimizer_kind_stage_matrix_is_exact.

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.

883-898: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Couple the active-stage map to the terminal-outcome map.

_ACTIVE_STAGES_BY_OPTIMIZER.get(optimizer_kind, ()) can return an empty tuple. The code then builds stage IN (), which is invalid SQL in SQLite.

This path is unreachable today. The preceding check at Line 828 already returns False for any optimizer kind that is absent from _TERMINAL_OUTCOMES_BY_OPTIMIZER, and both maps declare the same two kinds. The hazard appears only if a future change adds a family to one map and not the other.

Add an explicit guard so the two maps cannot drift silently.

3518-3539: 🗄️ Data Integrity & Integration | 🔵 Trivial

Plan for unbounded growth of the qualification cache.

The BEFORE DELETE trigger blocks every row removal. The table therefore grows by one row for each new (component_identity_digest, suite_digest) pair and never shrinks. Each analyst rebuild or suite revision adds a permanent row.

The rows are content-free digests, so this is not a privacy risk. Plan an offline archival or table-rebuild procedure before the row count becomes operationally relevant.

Name the failing combination in the matrix assertions.

Both tests iterate nested loops. If one combination fails, pytest reports a single test name. The report does not state which optimizer_kind, current_stage, terminal_stage, or outcome produced the failure. The reader must re-run and instrument the loop.

Add the combination to the assertion message. This keeps one test id and avoids a large parametrize expansion.

♻️ Example for the stage matrix
                 assert (
                     storage.advance_playbook_optimization_stage(

Assert that the rebuild restores the unique indexes.

The test proves that the widened optimizer-kind allowlist is applied. The rebuild in _enforce_playbook_optimization_job_constraints also drops the original table and must recreate uq_poj_active_discovery, uq_poj_active_attempt, uq_poj_active_target, idx_poj_target, and idx_poj_status. Add an assertion on sqlite_master so an index regression during a future rebuild is caught here.

Consider a single predecessor per stage.

Every entry repeats the same stage twice, for example ("evidence_frozen", "evidence_frozen"). The duplication exists only to fill the two fixed ? placeholders at Line 846. The terminal branch at Line 884 already builds placeholders dynamically. Using a variable-length tuple and the same dynamic placeholder join removes the duplication and makes the intent clear.

Assert the persisted row, not only the returned object.

The test asserts optimizer_kind on the value returned by create_or_get_playbook_optimization_job. That value can come from the in-memory input model. Reload the job so the assertion proves that SQLite accepted and stored offline_tuner_open_world.

💚 Proposed change
     saved = storage.create_or_get_playbook_optimization_job(open_world_job)
 
     assert saved.optimizer_kind == "offline_tuner_open_world"
+    reloaded = storage.get_playbook_optimization_job(saved.job_id)
+    assert reloaded is not None
+    assert reloaded.optimizer_kind == "offline_tuner_open_world"
+    assert reloaded.stage == "evidence_frozen"
