Summary

  • Add the shared open-world evidence identity and storage contracts needed to select offline-tuner evidence deterministically.
  • Preserve finalized session outcomes and bound maintenance and retention behavior without introducing customer replay infrastructure.
  • Keep Phase 2 stacked on the restored Phase 1 evidence foundation for focused review.

Changes

  • Add open-world optimization and session-outcome identity models.
  • Add storage contracts for deterministic evidence reconstruction and playbook optimization history.
  • Harden queued metering lifecycle startup, retained outcomes, request-source compatibility, trajectory digest streaming, and fixed exposure retention.
  • Align lifecycle tests with queued metering while preserving the Phase 1 exposure-before-metering invariant.

Test Plan

  • nice -n 10 uv run python -m reflexio_ext.scripts.phase2_evidence_gate from the enterprise checkout: 693 passed, 14 expected storage-specific skips.
  • Focused conflict-sensitive route and capability tests: 29 passed.
  • Ruff and Pyright passed for the restacked conflict-sensitive shared tests.

📝 Walkthrough

Walkthrough

The changes separate strict source validation from persisted source preservation, add streaming session trajectory digests, bound SQLite migration reads, and add receipt-aware generation finalization. They also add search exposure recording and harden service startup, timeout routing, worker cleanup, sweep registration, retention behavior, and client documentation.

Changes

Session outcome contracts and persistence

Layer / File(s) Summary
Source contract and persisted models
reflexio/models/api_schema/..., reflexio/server/services/storage/sqlite_storage/_requests.py, tests/models/..., tests/server/services/storage/test_storage_contract_requests.py, AI_AGENT_INTEGRATION.md
New source inputs use strict validation. Persisted models preserve legacy source strings.
Canonical trajectory digesting
reflexio/server/services/storage/session_outcome_identity.py, tests/models/test_session_outcome_identity.py
The identity module adds shared outcome constants, canonical request normalization, and a streaming digest accumulator.
SQLite finalization and migration
reflexio/server/services/storage/sqlite_storage/..., tests/server/services/storage/...
Session outcomes use canonical snapshots, bounded reads, keyset-paginated migration, normalized nullable sources, and retention protection.
Fixed retention limits
reflexio/server/services/storage/retention.py, reflexio/server/services/storage/retention_mixin.py
Retention targets can use fixed row limits and strict age cutoffs.

Receipt-aware generation

Layer / File(s) Summary
Finalization contracts and generation plans
reflexio/server/services/deferred_learning_plan.py, reflexio/server/services/base_generation_service.py, tests/server/services/test_base_generation_service.py
Generation plans track billable counts and receipt outcomes. Persistence and emission now handle run finalization separately.
Profile and playbook receipts
reflexio/server/services/profile/service.py, reflexio/server/services/playbook/service.py
Profile and playbook writes atomically persist outputs, bookmark advances, and finalization receipts. Duplicate finalizations reuse stored results.
Durable worker handling
reflexio/server/services/durable_learning/worker.py, tests/server/services/durable_learning/test_worker.py
Committed results remain complete when post-commit effects fail. Computed agent runs are abandoned on failed persistence or superseded claims.

Search and runtime safeguards

Layer / File(s) Summary
Search exposure recording
reflexio/server/routes/search.py, tests/server/routes/test_search_exposure_boundary.py, reflexio/client/client.py, docs/lib/methods/user-playbooks.ts, tests/client/test_search.py
Production-agent searches record returned playbook exposures and enforce documented workload, identifier, and correlation-field limits.
Service and worker startup
reflexio/cli/utils.py, reflexio/server/services/search_metering_worker.py, related tests
Embedding readiness gates backend startup. Partial metering-worker startup failures clean up started threads and allow retry.
Timeout and sweep registration
reflexio/server/middleware.py, reflexio/server/services/lineage/gc_scheduler.py, related tests
Playbook aggregation receives the synchronous timeout. Sweep registration ignores duplicate callbacks.
Runtime prerequisites
README.md
The README documents the linked SQLite runtime requirement and version check.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to f6147

The change expands evidence storage and queued learning behavior, but a post-commit failure can still leave a user’s learning lock held and prevent later jobs from running; the PR also retains a documentation lint failure that should be cleaned up before merge.

93-99: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Align source normalization with the writer.

Line 95 computes str(first["source"]). The writer computes str(first["source"] or "") at Line 244. If requests.source is ever NULL, the reader produces the string "None" and the writer produces "". The equality check at Line 248 then fails and record_session_outcome returns context_changed=True for every attempt on that session.

The current requests schema declares source TEXT NOT NULL DEFAULT '', so NULL is not reachable today. Applying the same normalization in both places removes the asymmetry.

                 user_id=str(first["user_id"]),

419-420: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

The fetch-size assertion covers only the conflict call.

Line 419 rebinds guarded_connection to a new _NoFetchAllConnection. That instance owns a fresh fetch_sizes list. The assertions at Lines 437-438 therefore inspect only the third record_session_outcome call. The sizes recorded during the first and retry calls are discarded.

The no-fetchall guard still applies to all three calls, so the main invariant holds. If you want the batch-size assertion to cover every call, keep both wrappers and assert over the combined list.

♻️ Proposed change
-    guarded_connection = _NoFetchAllConnection(raw_connection)
-    cast(Any, sqlite_storage).conn = guarded_connection
+    conflict_connection = _NoFetchAllConnection(raw_connection)

Derive the expected trajectory-query count from both chunk sizes

_prefetch_canonical_session_trajectory_digests uses RETENTION_DELETE_CHUNK (500), while migration batches use size 256. The 501 test rows therefore produce two queries today. If RETENTION_DELETE_CHUNK is lowered below 256, the assertion fails even though the migration remains correct. Derive the expected count from both constants, or assert the required lower bound.

113-127: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

__getattr__ does not cover implicit dunder lookups.

Python looks up special methods on the type, not the instance, so __getattr__ will not forward __iter__ or __next__ to the wrapped cursor. If the migration code ever iterates the cursor directly (for row in cursor), the wrapper raises TypeError instead of streaming, and the failure will look unrelated to the guard. Adding an explicit __iter__ that raises the same AssertionError as fetchall keeps the intent of the double clear.

The mock relies on a fixed execute call order.

connection.execute.side_effect supplies exactly three cursors in a fixed order. Any added or reordered query inside get_session_outcome_context raises StopIteration instead of a clear failure. Consider keying the cursors by statement text so the test fails with a readable message and survives benign query additions.

The two review-body nitpicks are already addressed in current head bb9f6ae38: _NoTrajectoryFetchAllCursor.__iter__ now fails explicitly so the migration remains bound to chunked fetchmany(), and the nullable-source test now uses a SQL-aware dispatcher with a clear assertion for unexpected statements. Focused verification passed (2 passed), and there are no unresolved review threads.

- Make session outcomes immutable, conflict-aware, reconstructable
records with server-owned contract and trajectory identities.
- Record synchronous search-exposure evidence and retain it under
governance-safe lifecycle rules.
- Keep billing limited to durable learnings created by online/resumable
extraction; derived aggregation and tuning remain unmetered.

- Add durable session-outcome identity fields, canonical digest helpers,
exact-retry behavior, and conflicting-finalization rejection.
- Add synchronous search-exposure recording with deterministic

## Summary

- preserve every user-playbook exposure ingested within the fixed 14-day
evidence window, even when the generic row cap is exceeded
- separate the optional retrieval subject from the served playbook owner
so unscoped searches remain attributable without becoming join-eligible
- normalize blank retrieval subjects to the unscoped representation
while retaining fail-closed owner checks for scoped searches

## Why

The Phase 1 offline-tuner evidence foundation requires complete,
reviewable exposure evidence. Generic row-cap retention could delete
current-window events, and the original exposure envelope overloaded
playbook ownership as the retrieval subject for unscoped searches. Both
behaviors could distort later evidence eligibility and exact-user
governance.

## Behavior

- exposure rows younger than 14 days are protected from row-cap deletion
- an exposure may carry a retrieval subject and a playbook owner
independently
- blank or whitespace retrieval subjects become unscoped
- scoped retrieval still rejects a user playbook owned by another user
before persistence

## Verification

- 46 shared exposure and retention contract tests passed after rebasing
onto current `main`
- final affected enterprise matrix: 164 passed, 9 adapter-applicability
skips
- Ruff formatting/lint, Pyright, import, diff, and gitlink checks passed
- correctness, security-resilience, architecture, and
verification-testing review lenses are clean

## Summary by CodeRabbit

* **New Features**
* Exposure records now preserve the playbook owner separately from the
person retrieving it.
  * Blank retrieval identifiers are normalized consistently.
* Playbook exposure data now includes governance subject references
where available.

* **Bug Fixes**
* Prevented exposure records from being created when a playbook belongs
to a different scoped user.
  * Added safeguards for unscoped exposure scenarios.

* **Data Retention**
* Open-world evidence, including playbook exposure records, is retained
for at least 14 days before cleanup.

401-454: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff

Consider extracting the shared receipt-finalization transaction.

ProfileGenerationService._finalize_write_plan_with_outcome and PlaybookGenerationService._finalize_write_plan_with_outcome in reflexio/server/services/playbook/service.py differ only in entity_type and in where the learning ids are derived. The double receipt read, the commit scope, the _FinalizationReceiptAlreadyExistsError rollback signal, and the conflict recovery are duplicated.

A base-class template method in BaseGenerationService could own the transaction and delegate the id derivation to a small hook. That keeps the receipt protocol in one place if it changes again.

In `@README.md`:
- Around line 111-115: Update the SQLite verification command in the
prerequisites documentation to use the universally available python executable
by default instead of uv run python, or provide separate commands for PyPI and
source installations.

In `@reflexio/client/client.py`:
- Line 911: Update ReflexioClient.search_user_playbooks to accept optional
request_id and session_id parameters, document each 255-character limit, and
forward both values to _build_request so direct searches retain their
correlation identifiers.

In `@reflexio/server/services/durable_learning/worker.py`:
- Around line 208-224: Update the side-effect handling around
emit_deferred_learning_side_effects so _release_user_lock is called from a
finally block, ensuring the per-user F4 lock is released whether emission
succeeds or raises. Preserve the existing exception logging, completion logging,
and return behavior.

In `@tests/cli/test_utils.py`:
- Line 349: Update the pytest.raises call’s match pattern to use a raw
regular-expression string, preserving the existing “embedding.*ready” pattern so
Ruff RUF043 is resolved.

In `@tests/server/services/durable_learning/test_worker.py`:
- Around line 824-865: Update the post-commit emission failure test around
DurableLearningWorker._process_job to explicitly acquire and hold the F4 lock
for the first job before emit_then_raise runs, then process a later same-user
job and assert it acquires the lock successfully. Keep the existing finalization
and completed-job assertions, and ensure the test verifies the lock is released
after emit_deferred_learning_side_effects raises.
