Summary

Test plan

  • python -m unittest discover -s application/tests/harvester_test -p '*_test.py' (integration git tests skip in sandbox; should run in CI)
  • make lint
  • CI green on this PR
  • Manual: seed a tiny repos.yaml, python cre.py --run_harvester --run_id demo --cache_file …, then --run_noise_filter / --run_librarian or make oie-pipeline

Made with Cursor

ParthAggarwal16 and others added 26 commits August 22, 2026 20:49
Land week 7–8 harvester work on top of #1029, fix blockers (git argv,
heading fences, ChangeRecord-shaped chunks, durable checkpoints), add
cre.py --run_harvester → harvest_input, and ship a production A→B→C
orchestrator so the pipeline can run end to end.

Maintainer line-by-line review (self)

Reviewed against docs/gsoc_2026_module_a/blockers.md + the A→B queue contract.

Blockers addressed

  • B1/B2 git checkout no longer pathspec-traps; get_file_at_commit uses cat-file -s size gate + --end-of-options.
  • B3 heading extractor skips fenced + indented code.
  • B4 artifact_id / locator.id validation tightened.
  • B6/B7 checkpoints go through CheckpointStore (no empty SHA).
  • B8 UNCHANGED refresh of commit/run metadata.
  • B10 chunks carry pipeline_run_id / source.repo / locator and validate via Module B ChangeRecord.
  • B11/B12 no LlamaIndex on prod requirements; chunking honors repos.yaml strategies.
  • S1–S3 run_harvester + harvest_input writer + CLI; orchestrator calls A for real.

Residual / accept

  • In-process ArtifactRegistry is still per-process (OK; durable progress is checkpoint SHA).
  • Git integration tests skip when the environment blocks .git/config writes; CI should run them.
  • First harvest uses the empty-tree SHA to list all files — intentional cold start.
  • RSS / extra repos / nightly Action still out of scope (runbook notes orchestrator/cron owns schedule).

Verdict

Approve to merge once CI is green. E2E path: cre.py --run_harvester--run_noise_filter--run_librarian --run_id, or make oie-pipeline.

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

Merge Risk: 🟠 High · up to 8e62b

The PR adds an A→B→C production pipeline and durable decision handoff, but safety-unevaluated decisions can currently be stored and reported as a successful run, allowing downstream processing without a preserved safety result. Additional open issues can skip harvested documents, merge concurrent runs, accept malformed repositories, or duplicate ingested content, so the PR is not merge-ready until these risks are fixed or explicitly accepted.

Line-by-line review (maintainer pass)

Reviewed tip f86e5b88 for Module A handoff + OIE A→B→C. Verdict: merge when CI is green.

Contract / handoff (blockers)

  • run_harvester(session, pipeline_run_id) → RunSummary mirrors B’s shape; CLI --run_harvester --run_id exits 1 on degraded.
  • write_harvest_input enforces payload pipeline_run_id == column; inserts status=pending.
  • Chunks validate as Module B ChangeRecord (IngestChunkRecord + validator).
  • Durable checkpoints via CheckpointStore / harvester_checkpoint (no empty-SHA trap).
  • No LlamaIndex on prod/dev requirements; chunking is markdown_heading / fixed_size from repos.yaml.

Orchestrator

  • run_oie_pipeline sequences A→B→C with stop_on_error; stages always db_connect so injected B/C get a real session.
  • Module C uses run_librarian_queue + DbEnvelopeSink (not a fire-and-forget stub).
  • Declared C NullSafetyGuard degradation maps to stage degraded (pipeline ok); A/B partial degraded still maps to error.
  • CLI no longer nests Flask app_context around db_connect (fixes wrong-context pop).

Docs / smoke

  • docs/gsoc_2026_module_a/{blockers,line-by-line,runbook}.md land with the PR.
  • make oie-e2e-smoke / scripts/run_oie_e2e_smoke.py hermetic A→B→C: harvest_input → knowledge_queue → decision_queue + consumed_at (stub B classifier + stub C retriever/reranker/scaler). Local run: orchestrator_ok=true, processed/queued/consumed/decisions all ≥ 1.

Residual (non-blocking for this PR)

  • Live B needs a configured LLM classifier; live C needs embeddings + cross-encoder (requirements-dev).
  • SafetyGuard detector + graph writer remain Module C W8b / Module D.
  • In-memory checkpoint_manager may still exist beside CheckpointStore — cleanup later if unused.
  • Nightly GH Action for OIE not in scope here.

Inline comments:
In `@application/utils/harvester/chunk_record_builder.py`:
- Around line 103-105: Add the missing imports for ChunkingConfig from .schemas
and DocumentChunker from .chunker in chunk_record_builder.py, ensuring both the
chunk_document annotation and DocumentChunker(config) call resolve during module
loading and execution.

In `@application/utils/harvester/chunker.py`:
- Around line 63-64: Update the section-building logic in _markdown_heading to
use each heading’s next heading start as the chunk boundary, preventing ancestor
sections from including descendant content multiple times. Retain the full
HeadingNode start_line/end_line ranges only for heading-path metadata.

In `@application/utils/harvester/document_validator.py`:
- Line 30: Update the repository validation around the source.repository and
artifact_id checks to use one shared helper that requires exactly two nonempty
components separated by a single “/”. Reject values with no separator, multiple
separators, or empty owner/repository segments, and apply the same validation
consistently in both locations.

In `@application/utils/harvester/harvest_writer.py`:
- Around line 39-45: Update write_harvest_input to validate and serialize the
complete batch, including consistent pipeline_run_id values, before the first
session.add call. Ensure validation failures cannot leave earlier HarvestInput
objects pending; preserve atomic batch behavior without persisting partial rows.

In `@application/utils/harvester/heading_extractor.py`:
- Around line 62-64: Update the fence detection in the heading extraction flow
to inspect the line’s leading indentation and toggle fence.in_fence only for ```
or ~~~ delimiters indented by at most three spaces; leave indented code to
_is_indented_code(). Add a regression test covering an indented fence-like line
followed by a real heading.

In `@application/utils/harvester/incremental_pipeline.py`:
- Line 80: Move the _persist_checkpoint call in the process flow so it runs only
after chunking and write_harvest_input complete successfully; ensure any failure
in those operations leaves the repository checkpoint unchanged and do not
advance it for a failed run.

Apply the same fix in `@application/utils/harvester/checkpoint_manager.py` at line
12.

In `@application/utils/oie_orchestrator/pipeline.py`:
- Around line 231-233: Update the default pipeline_run_id generation in the run
orchestration flow to append a UUID-derived suffix to the UTC timestamp,
ensuring invocations in the same second receive distinct identifiers while
preserving explicitly supplied, trimmed pipeline_run_id values.
- Line 191: Update run_librarian_live() and the orchestrator’s Module C handling
to return and propagate the actual RunSummary instead of replacing it with a
synthetic dictionary; preserve degraded and other non-"ok" statuses, and mark
Module C as an error whenever its status is not exactly "ok" so
scripts/run_oie_pipeline.py returns a nonzero result.

In `@docs/gsoc_2026_module_a/blockers.md`:
- Line 4: Update the status line in blockers.md to mark the blocker list as
historical/resolved, consistent with the completed workflow documented in
runbook.md, so operators do not follow obsolete manual-seeding guidance.

In `@docs/gsoc_2026_module_a/runbook.md`:
- Line 39: Update the runbook’s Module A degraded-status guidance to reflect
that _stage_module_a converts degraded to error and the default stop_on_error
behavior prevents Modules B and C from running; document how to continue after a
degraded run or explicitly document the resulting stop behavior and pending
harvest_input rows.

Prevent ancestor sections from re-emitting descendant content.

HeadingExtractor.extract sets an ancestor HeadingNode.end_line after nested headings. _markdown_heading then creates overlapping sections from each start_line/end_line pair. With a large token budget, descendant text can appear in multiple ingest records. Use the next heading start for chunk boundaries and retain enclosing ranges only for heading-path metadata.

Validate exactly one nonempty owner/repository separator.

"/" and "owner/repo/extra" pass these checks. They are not valid owner/repository identifiers. The validator can then accept malformed source.repository and artifact_id values.

Use one shared helper that requires exactly two nonempty repository components.

SQLAlchemy Session.add pending objects Session.commit flush official documentation

💡 Result:

In SQLAlchemy, managing objects through the Session involves a unit of work pattern that tracks changes in memory before synchronizing them with the database [1][2]. Session.add(instance) When you call session.add(instance) on a transient object (a new instance not yet associated with a session), the object enters a pending state [3][4]. It is not yet inserted into the database [3][2]. The Session keeps track of these pending objects in its internal state until a flush occurs [3][2]. Session.flush The flush process synchronizes the current state of the objects in memory with the database [4][5]. It emits the necessary SQL (INSERT, UPDATE, DELETE) to the database's transaction buffer, but it does not finalize the transaction [2][4][5]. You can call session.flush manually at any time to push changes to the database without committing the transaction [1][2]. Session.commit The session.commit method serves two primary purposes: 1. It unconditionally calls session.flush to ensure all pending changes are sent to the database [1][4]. 2. It executes the COMMIT command to finalize the transaction in the database [1][4]. Key points regarding the interaction: - Automatic Flushing: The Session is configured by default to perform an autoflush before queries are executed and automatically performs a flush when session.commit is called [1][2]. - Transaction Demarcation: Upon session.commit, the transaction is ended, and all objects associated with the session are typically expired [3][4]. This ensures that the next time you access an attribute on an object, the session re-fetches the current data from the database [4][5]. - Dependency Management: The Session automatically orders operations (INSERTs, UPDATEs, DELETEs) based on its unit of work dependency solver to maintain database integrity during the flush process [4][5].

Citations:


Validate the complete batch before adding rows to the SQLAlchemy session.

If a later record has a different pipeline_run_id, write_harvest_input raises after earlier HarvestInput objects are pending.

Do not treat indented code as a fence delimiter.

line.lstrip() makes a four-space-indented ````` line toggle in_fence before `_is_indented_code()` can ignore it. A later real heading is then skipped. This also makes the fence state depend on code content.

Recognize fence delimiters only when indentation is at most three spaces. Add a regression test with an indented fence-like line followed by a real heading.

Advance the checkpoint only after outputs are recoverable.

The repository checkpoint is durable, but it is committed before chunk construction and harvest_input persistence finish. If either operation fails, a later run can treat the commit as processed and permanently skip its missing outputs.

Advance the checkpoint only after successful output persistence, or use an explicit recoverable completion state; do not leave the checkpoint ahead of staged data.

Return and propagate the Module C summary.

run_librarian_live() prints RunSummary.to_json() but returns None. The orchestrator replaces that result with a synthetic dictionary and always sets module_c_librarian.status to "ok". A RunSummary.status of degraded: ... therefore produces an overall success result, and scripts/run_oie_pipeline.py returns code 0. Return the summary and treat every non-"ok" Module C status as an error.

Generate a unique default pipeline_run_id.

When two invocations omit pipeline_run_id in the same UTC second, both receive the same value. Module A then writes both runs into one harvest_input scope, and later stages can process the combined rows as one run.

Append a UUID suffix to the timestamp.

Proposed fix
-    run_id = (pipeline_run_id or "").strip() or (
-        datetime.now(timezone.utc).strftime("%Y%m%dT%H%M%SZ")
-    )
+    run_id = (pipeline_run_id or "").strip() or (
+        f"{datetime.now(timezone.utc).strftime('%Y%m%dT%H%M%SZ')}-{uuid.uuid4().hex}"
