No-QA generation runs and TEI-P5 retrieval (4.3.2)

[leynos]

Summary

This implementation completes roadmap task 4.3.2 — No-QA generation runs
and TEI-P5 retrieval, the second half of the source-to-script REST vertical
slice defined in ADR 009.

The design and build phases are complete. The living ExecPlan records all
milestone decisions, discoveries, progress, and validation evidence:

docs/execplans/4-3-2-no-qa-generation-runs-and-tei-p5-retrieval.md

Implemented behaviour

An integration client can now:

1. Create an idempotent run with quality_mode=draft_without_qa, a rationale,
   and actor metadata.
2. Poll durable run state and the append-only event log until terminal.
3. Generate from ingestion sources plus bound host and guest profiles.
4. Persist validated, revisioned canonical TEI with skipped-QA provenance.
5. Retrieve a JSON TEI envelope or download application/tei+xml with an ETag
   and attachment metadata.

Identical idempotent replays preserve the run id, Location, and
Retry-After; changed bodies conflict. Provider and TEI failures become
classified terminal run state.

Architecture

• GenerationRunLauncher isolates scheduling from durable execution state; the
  first adapter runs in-process with bounded concurrency and shutdown draining.
• Generation runs, events, claims, leases, error categories, and TEI revisions
  persist through SQLAlchemy adapters and Alembic migrations.
• DraftScriptGenerator isolates the single-pass LLM draft policy from the
  launcher and its future roadmap 4.4.1 successor.
• ADR 016 records execution, episode materialization, optimistic persistence,
  recovery hooks, HTTP status choices, and content negotiation.

Validation

• make check-fmt
• make typecheck
• make lint — Pylint 10.00/10
• make check-migrations
• make test — 1,076 passed, 1 skipped
• make markdownlint
• make nixie
• Vidai Mock behavioural slice — 7 passed with vidaimock 0.1.3
• CodeRabbit milestone reviews — zero findings after each reviewed milestone

Summary by Sourcery

Deliver the no-QA source-to-script REST slice from ready ingestion jobs through durable generation runs and downloadable TEI-P5 drafts.

New Features:

• Add REST endpoints for creating, polling, and inspecting no-QA generation runs from ready ingestion jobs.
• Generate and persist validated TEI-P5 drafts with skipped-QA provenance, revision metadata, source content, and presenter profile context.
• Support JSON TEI envelopes and downloadable application/tei+xml representations with content negotiation, ETags, conditional requests, and attachment metadata.

Bug Fixes:

• Preserve idempotent generation-run response metadata and scope idempotency keys by principal.
• Prevent duplicate execution and materialization through conditional claims, transactional association, optimistic TEI revisions, and serialized shutdown handling.
• Classify provider, TEI, persistence, overload, and cancellation failures as durable terminal run state and events.

Enhancements:

• Introduce an in-process bounded generation launcher with detached units of work, leases, lifecycle events, cost recording, tracing, and structured metrics.
• Extend canonical generation-run and episode models, storage ports, SQLAlchemy repositories, and migrations for durable run, event, and TEI persistence.
• Add runtime configuration and composition wiring for OpenAI-compatible draft generation, pricing snapshots, observability, and ordered resource shutdown.

Documentation:

• Document the no-QA generation workflow, TEI retrieval contract, launcher architecture, operational limitations, and manual expired-lease recovery procedure.
• Record the implementation decisions in ADR 016 and mark roadmap item 4.3.2 complete.

Tests:

• Add unit, integration, concurrency, persistence, observability, and Vidai Mock behavioural coverage for the complete no-QA source-to-script flow.

Chores:

• Refine generation-run ports and adapter structure while preserving checkpoint support and existing intake API behaviour.

Poem

Runs wake, drafts take flight,
TEI gains a revisioned write.
Events record each state transition,
Polling serves the run condition.
XML returns with headers bright,
QA waits for later review.

Merge Risk: 🟡 Moderate · up to f8994

The generation-run flow still risks incorrect state and error reporting, and its concurrency guarantees are not adequately demonstrated; the required quality gate also remains failing. These issues should be fixed or explicitly accepted before merging.

Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

• Ignore

❌ Failed checks (1 error, 6 warnings, 3 inconclusive)

Check name	Status	Explanation	Resolution
Security And Privacy	❌ Error	New run/event/TEI routes read by UUID without resource checks, while create_app_from_env relies on default PermitAll; this exposes run metadata, events, and raw TEI to unauthenticated callers.	Require policy-backed authorisation in production. Enforce principal ownership for run, event, ingestion, and episode access, and derive the audit actor from the authenticated principal.
User-Facing Documentation	⚠️ Warning	The PR adds new generation-run and TEI REST behaviour, but provides no n+1 migration document; the project version is 0.1.0 and the README still says the user guide is coming soon.	Add a 0.2.0 migration document and update the README to signpost the new no-QA generation and TEI retrieval workflow.
Testing (Property / Proof)	⚠️ Warning	Flag the gap: the PR adds SQL claims, event sequencing, pagination, idempotency, and launcher state transitions, but adds no Hypothesis generators for these paths; only existing in-memory propertie...	Add substantive Hypothesis state-machine tests for SQL and launcher behaviour, varying event batches, principals, pages, leases, capacity, interleavings, and shutdown transitions.
Domain Architecture	⚠️ Warning	The new generation_persistence.py imports SQLAlchemy IntegrityError and inspects source_documents_pkey and driver messages, so application/domain logic depends on ORM and storage details.	Move duplicate-race detection and rollback into the SQLAlchemy adapter. Expose a domain-shaped result or exception, then remove SQLAlchemy imports and constraint strings from generation_persistence.py.
Observability	⚠️ Warning	New polling, event-listing, and TEI GET handlers cross the storage boundary but have no spans; only run creation and launcher execution call start_span.	Inject TracerPort into all new GET resources and wrap storage and representation operations with bounded operation, outcome, and failure-category attributes.
Performance And Resource Use	⚠️ Warning	The new launcher activates blocking FilesystemObjectStore reads on async tasks, while source materialisation collects all pages and uploaded bytes without a source-count/read bound.	Enforce total source/count and byte limits, avoid b"".join for unbounded reads, and move blocking filesystem access to an appropriate blocking pool or async adapter.
Concurrency And State	⚠️ Warning	The new launcher holds the SQL run-row lock after claim while awaiting source hydration and binding queries; uploaded hydration uses blocking filesystem I/O, and no lock-contention test covers this...	Commit the claim before source and binding I/O, then load inputs in a separate UOW. Add a barrier test proving delayed hydration does not block concurrent run-state operations.
Testing (Overall)	❓ Inconclusive	Investigation is still in progress; no final assessment has been submitted.	Continue reviewing the changed behaviour and its substantive tests.
Developer Documentation	❓ Inconclusive	Investigation started; no verdict yet.	Inspect the pull-request diff and the developer, design, roadmap, and execplan documents before deciding.
Unit Architecture	❓ Inconclusive	Initial evidence is not yet sufficient to assess whether the changed units violate the explicit architecture conditions.	Inspect the pull-request diff and changed query, command, runtime, and API paths for hidden side-effects or non-injected dependencies.

Excess Number of Function Arguments

tests/test_generation_run_port_contract.py: NoopGenerationRunPort.update_run_status has 6 arguments, max arguments = 4
episodic/canonical/adapters/generation_runs.py: InMemoryGenerationRunStore.update_run_status has 6 arguments, max arguments = 4
episodic/canonical/generation_run_ports.py: GenerationRunRepository.update_run_status has 6 arguments, max arguments = 4
episodic/canonical/storage/generation_runs.py: SqlAlchemyGenerationRunStore.update_run_status has 6 arguments, max arguments = 4

Why does this problem occur?

Functions with many arguments indicate either a) low cohesion where the function has too many responsibilities, or b) a missing abstraction that encapsulates those arguments.
The threshold for the Python language is 4 function arguments.

How to fix it?

Start by investigating the responsibilities of the function. Make sure it doesn't do too many things, in which case it should be split into smaller and more cohesive functions. Consider the refactoring INTRODUCE PARAMETER OBJECT to encapsulate arguments that refer to the same logical concept.

Overall Code Complexity

episodic/canonical/adapters/generation_runs.py:

What lead to degradation?

This module has a mean cyclomatic complexity of 4.10 across 10 functions. The mean complexity threshold is 4

Why does this problem occur?

Overall Code Complexity is measured by the mean cyclomatic complexity across all functions in the file. The lower the number, the better.
Cyclomatic complexity is a function level metric that measures the number of logical branches (if-else, loops, etc.). Cyclomatic complexity is a rough complexity measure, but useful as a way of estimating the minimum number of unit tests you would need. As such, prefer functions with low cyclomatic complexity (2-3 branches).

How to fix it?

You address the overall cyclomatic complexity by a) modularizing the code, and b) abstract away the complexity. Let's look at some examples:
Modularizing the Code: Do an X-Ray and inspect the local hotspots. Are there any complex conditional expressions? If yes, then do a DECOMPOSE CONDITIONAL refactoring. Extract the conditional logic into a separate function and put a good name on that function. This clarifies the intent and makes the original function easier to read. Repeat until all complex conditional expressions have been simplified.

Code Duplication

tests/test_generation_run_port_contract_support.py:

What lead to degradation?

The module contains 7 functions with similar structure: NoopGenerationRunPort.cancel_checkpoint,NoopGenerationRunPort.get_checkpoint,NoopGenerationRunPort.get_run,NoopGenerationRunPort.list_events and 3 more functions

Why does this problem occur?

Duplicated code often leads to code that's harder to change since the same logical change has to be done in multiple functions. More duplication gives lower code health.

How to fix it?

A certain degree of duplicated code might be acceptable. The problems start when it is the same behavior that is duplicated across the functions in the module, ie. a violation of the Don't Repeat Yourself (DRY) principle. DRY violations lead to code that is changed together in predictable patterns, which is both expensive and risky. DRY violations can be identified using CodeScene's X-Ray analysis to detect clusters of change coupled functions with high code similarity. Read More
Once you have identified the similarities across functions, look to extract and encapsulate the concept that varies into its own function(s). These shared abstractions can then be re-used, which minimizes the amount of duplication and simplifies change.

episodic/canonical/generation_persistence.py — _project_source_documents, _require_projected_source_documents
episodic/canonical/generation_persistence.py — add _projected_source_document_ids

Apply a focused refactor. Do not suppress this diagnostic.

I validated the current codegraph at revision 99fa7a29c91573eef36215be494dac3f517ee734.

The duplication is real. Both functions load all persisted SourceDocument records for sources[0].ingestion_job_id and build a set[uuid.UUID] of document IDs. The functions then perform different operations:

• _project_source_documents skips already-persisted deterministic IDs before it resolves uploads and inserts source documents.
• _require_projected_source_documents verifies that a duplicate-key race left every expected deterministic ID durable after rollback.

Keep both functions. Extract only the repeated read-and-project operation into this private helper:

async def _projected_source_document_ids(
    uow: CanonicalUnitOfWork,
    ingestion_job_id: uuid.UUID,
) -> set[uuid.UUID]:
    """Return persisted source-document IDs for one ingestion job."""
    return {
        document.id
        for document in await uow.source_documents.list_for_job(ingestion_job_id)
    }

Update _project_source_documents:

existing_document_ids = await _projected_source_document_ids(
    uow,
    sources[0].ingestion_job_id,
)

Update _require_projected_source_documents:

projected_ids = await _projected_source_document_ids(
    uow,
    sources[0].ingestion_job_id,
)

Preserve the existing order and boundaries:

1. Keep _project_source_documents before the projection commit().
2. Keep IntegrityError handling in materialise_episode_from_ingestion.
3. Keep rollback() before _require_projected_source_documents.
4. Keep _require_projected_source_documents limited to duplicate-key recovery.
5. Do not merge insertion and post-race verification into one function.
6. Do not alter deterministic uuid.uuid5(episode_id, str(source.id)) generation.

The existing tests already cover the important behaviour. In particular, test_materialise_verifies_duplicate_projection_rows requires two source-document reads: one stale pre-insert read and one post-rollback verification read. The helper must preserve both calls.

• Extract the common persisted-source-document-ID query.
• Preserve projection, rollback, and duplicate-race verification behaviour.
• Run the focused persistence, failure, and concurrency tests.

AI coding agent prompt

Remove the confirmed duplicate query structure in the generation-persistence module.

Target file and symbols:
- `episodic/canonical/generation_persistence.py`
  - `_project_source_documents`
  - `_require_projected_source_documents`
  - add `_projected_source_document_ids`

Validated current revision:
- `99fa7a29c91573eef36215be494dac3f517ee734`

Current-codegraph facts:
- `_project_source_documents` is on Lines 221-250.
- `_require_projected_source_documents` is on Lines 252-267.
- Both functions call:
  `uow.source_documents.list_for_job(sources[0].ingestion_job_id)`.
- Both functions derive a set of persisted `SourceDocument.id` values.
- `_project_source_documents` uses that set to skip existing deterministic
  source-document projections before upload lookup and insertion.
- `_require_projected_source_documents` uses that set after a duplicate-key
  rollback to verify that all deterministic projections exist.
- The two functions have different responsibilities. Keep them separate.

Required changes:
1. Add this private helper near the two target functions:

   ```python
   async def _projected_source_document_ids(
       uow: CanonicalUnitOfWork,
       ingestion_job_id: uuid.UUID,
   ) -> set[uuid.UUID]:
       """Return persisted source-document IDs for one ingestion job."""
       return {
           document.id
           for document in await uow.source_documents.list_for_job(ingestion_job_id)
       }
   ```

2. In `_project_source_documents`, replace the inline repository query and
   set comprehension with:

   ```python
   existing_document_ids = await _projected_source_document_ids(
       uow,
       sources[0].ingestion_job_id,
   )
   ```

3. In `_require_projected_source_documents`, replace the inline repository
   query and set comprehension with:

   ```python
   projected_ids = await _projected_source_document_ids(
       uow,
       sources[0].ingestion_job_id,
   )
   ```

4. Preserve all existing behaviour:
   - keep `_project_source_documents` and `_require_projected_source_documents`
     as separate functions;
   - keep deterministic IDs as `uuid.uuid5(episode_id, str(source.id))`;
   - keep upload resolution only in `_project_source_documents`;
   - keep `SourceDocumentProjectionError` and its missing-ID calculation;
   - keep the `IntegrityError` handler and rollback in
     `materialise_episode_from_ingestion`;
   - keep post-rollback verification limited to duplicate
     `source_documents` primary-key errors;
   - keep source paging before the ingestion-job lock;
   - do not change public interfaces or transaction boundaries.

5. Do not add a cache. The projection path and duplicate-race verification path
   require separate database reads.

6. Add tests only if existing tests do not cover the helper through the public
   flow. Keep the patch limited to the persistence module unless a focused test
   needs adjustment.

Validation:
1. Run:
   - `uv run pytest tests/test_generation_persistence.py`
   - `uv run pytest tests/test_generation_persistence_failures.py`
   - `uv run pytest tests/test_generation_persistence_locking.py`
2. Run the formatter, linter, and type checker for the changed module.
3. Confirm that
   `test_materialise_verifies_duplicate_projection_rows` still observes two
   source-document reads.

Deliver:
- A minimal patch.
- A validation report with exact commands and results.
- A short statement that the helper shares only the persisted-ID query and
  preserves separate projection and duplicate-race verification responsibilities.

Build the message before calling super().

Assign the formatted message to a local message variable. Pass that variable
to super().__init__().

Proposed fix

     def __init__(self, ingestion_job_id: uuid.UUID) -> None:
         """Initialize an ingestion-job persistence error."""
         self.ingestion_job_id = ingestion_job_id
-        super().__init__(
-            self.message_template.format(ingestion_job_id=ingestion_job_id)
-        )
+        message = self.message_template.format(ingestion_job_id=ingestion_job_id)
+        super().__init__(message)

As per coding guidelines, “Construct exception messages in a variable and pass
one message object to the exception constructor, rather than embedding direct
strings or f-strings in the constructor call.”

Type the session_factory fixture directly.

Change session_factory: object to async_sessionmaker[AsyncSession]. Remove
the immediate typ.cast() and use session_factory directly.

As per coding guidelines, “Use typing everywhere.” As per path instructions,
“All code must have clear type hints using modern style”.
