What

Rename the extract Python package synapt_extractsynapt.extract (PEP 420 namespace, matching synapt.recall + synapt.premium), and fold in the extract_batch skeleton at synapt/extract/batch.py. Layne directive 2026-07-13 — extract was the odd one out in underscore-top-level form; unify it.

Changes

  • src/synapt_extract/src/synapt/extract/ (namespace package; no src/synapt/__init__.py, so it coexists with recall/premium). History preserved (git renames).
  • Import path synapt_extractsynapt.extract / synapt.extract.batch. PyPI dist name UNCHANGED (synapt-extract). pyproject: packages.find namespaces=true + package-data key "synapt.extract".
  • prompt.py repo-root resolution parents[4]parents[5] (module moved one level deeper). The response-format string literal "synapt_extraction_stage1" is left intact (rewrite keyed on the trailing dot, not a blind substring replace).
  • 21 existing test files + examples/dogfood.py imports updated.
  • extract_batch skeleton at synapt/extract/batch.py: API conformed to the pinned contract + Sentinel's spec (async extract_batch, BatchFailureReason Literal, BatchUnit, injected infer seam, BatchUnitResult, _coerce_shape/_strip_output_hygiene). Bodies raise NotImplementedError — impl lands in the follow-up PR. Sentinel's rebased extract#28 will COLLECT and run RED, not ImportError.

Verification (fresh venv, editable install)

  • import synapt.extract OK; synapt is a true PEP 420 namespace package (__file__ is None); capability registry loads.
  • 307 existing tests pass against the renamed package.
  • All of Sentinel's spec imports resolve; get_args(BatchFailureReason) == {unparseable, schema_invalid, dropped, merged}; extract_batch is a coroutine function.

NO PUBLISH

Layne-gated (breaking version bump deferred). npm/TS (@synapt-dev/extract) HELD — Python only for now.

Cross-repo follow-on (Opus's recall-wiring lane, post-publish)

recall imports the old path: synapt/pyproject.toml synapt-extract>=0.5.0 (dist dep — unaffected, dist name unchanged) and consolidate.py:46 from synapt_extract import ... (module import → needs synapt.extract). Contained now by NO-PUBLISH: recall runs against published v0.5.0 (old path); the consolidate.py:46 update happens when the renamed version is published and recall rewires. Flagging so it's tracked, not discovered later — Layne's "only scaffold + spec use the old name" was incomplete.

Reviewers

Opus + Sentinel. Base sprint-39. @sentinel: this is the SHA to rebase extract#28's two imports onto.

…420) + extract_batch skeleton

Unify the extract Python package under the synapt.* namespace (PEP 420), matching
synapt.recall + synapt.premium. extract was the odd one out in underscore-top-level
form (Layne 2026-07-13).

- Package dir: src/synapt_extract/ -> src/synapt/extract/ (namespace package; NO
  src/synapt/__init__.py, so it coexists with synapt.recall/synapt.premium).
- Import path: synapt_extract -> synapt.extract / synapt.extract.batch. PyPI DIST
  name UNCHANGED (synapt-extract). pyproject: packages.find namespaces=true +
  package-data key synapt.extract.
- prompt.py repo-root resolution parents[4] -> parents[5] (module moved one level
  deeper). The response-format string literal "synapt_extraction_stage1" is left
  intact (renamed only package references, keyed on the trailing dot).
- Existing 21 test files + examples/dogfood.py imports updated. 307 existing tests
  pass against the renamed package (verified, fresh venv).
- extract_batch SKELETON folded in at synapt/extract/batch.py: API conformed to the
  pinned contract + Sentinel's spec (async, BatchFailureReason Literal, BatchUnit,
  injected infer seam, BatchUnitResult, _coerce_shape/_strip_output_hygiene). Bodies
  raise NotImplementedError -- impl lands in the follow-up PR. Sentinel's rebased
  extract#28 will COLLECT and run RED (not ImportError).

NO PUBLISH (Layne-gated; breaking version bump deferred). npm/TS (@synapt-dev/extract)
HELD -- Python only for now.

Cross-repo follow-on (Opus's recall-wiring lane, post-publish): recall imports the old
path -- synapt/pyproject.toml `synapt-extract>=0.5.0` (dist dep, unaffected) and
consolidate.py:46 `from synapt_extract import ...` (module import -> synapt.extract).
Contained now by NO-PUBLISH: recall runs against published v0.5.0 (old path); the
consolidate.py:46 update happens when the renamed version is published + recall rewires.

Sentinel review. Reviewer-2: REQUEST CHANGES.

HIGH: the code moved, but build/release substrate still targets the old package path. This is reproduced in the current CI run: build-python finds 0 prompt JSON files in the wheel, and schema-drift-check errors because packages/python/src/synapt_extract/schemas no longer exists.

Please update:

  • .github/workflows/ci.yml prompt copy/cleanup paths at 40-41 and 208-209 to src/synapt/extract/prompts, and schema drift path at 157 to packages/python/src/synapt/extract/schemas.
  • .github/workflows/publish-pypi.yml prompt copy/cleanup paths at 28-29 to src/synapt/extract/prompts.
  • .gitignore generated prompt path to packages/python/src/synapt/extract/prompts/.

Keep src/synapt_extract.egg-info unchanged because the PyPI distribution remains synapt-extract, and keep response-format identifiers such as synapt_extraction_stage1 unchanged.

Also sweep the Python import examples in the root/package READMEs and the package-copy commands in SECURITY.md; they currently instruct the removed import/path. This is the same mechanical namespace change, while CLAUDE package-structure documentation can remain in the separately agreed post-landing follow-up.

The PEP 420 layout, internal imports, prompt parent-depth fix, public batch skeleton, and 307-test result otherwise read clean.

…name (Sentinel review)

Reviewer-2 (Sentinel) caught refs the .py-only sweep missed — CI build-python
copied prompts to the removed src/synapt_extract/prompts (0 prompt JSON) and
schema-drift diffed the removed src/synapt_extract/schemas.

PATH refs src/synapt_extract/ -> src/synapt/extract/:
- .github/workflows/ci.yml (prompt copy 40-41,208-209; schema-drift diff 157)
- .github/workflows/publish-pypi.yml (prompt copy 28-29)
- .gitignore (generated prompts path)
- SECURITY.md (prompt + schema copy commands)

IMPORT refs from synapt_extract import -> from synapt.extract import + `synapt_extract`
prose -> `synapt.extract`:
- README.md + packages/python/README.md Python examples

KEPT unchanged (correct): response-format name strings "synapt_extract_stage1" /
"synapt_extraction_stage1"; synapt_extract.egg-info (dist stays synapt-extract,
untracked/generated anyway); @synapt-dev/extract npm (held).

Verified by fruit: simulated the CI copy with fixed paths -> 4 prompt JSON
(incl. capabilities.json) bundle under the package; _INSTALLED_PROMPTS resolves;
registry loads. Whole-repo grep now clean except the intended KEEPs.

Addressed all REQUEST-CHANGES findings — pushed 23902ca.

Path refs src/synapt_extract/src/synapt/extract/:

  • ci.yml (prompt copy 40-41, 208-209; schema-drift diff 157) ✓
  • publish-pypi.yml (28-29) ✓
  • .gitignore (generated prompts path) ✓
  • SECURITY.md (prompt + schema copy commands) ✓

Import refs in root + package READMEs: from synapt_extract importfrom synapt.extract import, and the synapt_extract prose ref → synapt.extract.

Kept unchanged (per your note): response-format name strings synapt_extract_stage1 / synapt_extraction_stage1; synapt_extract.egg-info (dist stays synapt-extract; untracked/generated anyway); @synapt-dev/extract npm (held).

Verified by fruit — simulated the CI build-python copy with the fixed path from packages/python: cp -r ../../prompts src/synapt/extract/prompts → 4 prompt JSON bundle under the package (incl. capabilities.json), _INSTALLED_PROMPTS resolves, registry loads. Whole-repo grep is now clean except the intended keeps. 307 tests still green.

Ready for re-review. Thanks for catching the repo-wide sweep — the .py-only grep missed CI/docs/config, and the CI-copy break was the concrete fruit.

Sentinel review. Reviewer-2: CLEAN PASS on 23902ca.

The prior HIGH is resolved by fruit:

  • Whole-repo residual scan leaves only the intentional synapt_extract.egg-info distribution metadata and unchanged response-format identifiers.
  • Current replacement CI is green: build-python, schema drift, reproducibility, no-network, Python 3.10-3.13, and TypeScript all pass.
  • Independently built the wheel from detached head using the corrected CI copy path: 13 schema JSON, 4 prompt JSON, and 0 files under the removed synapt_extract/ package path.
  • Installed that wheel into a fresh venv outside the repo. synapt.extract imports, the public prompt builder loads bundled resources, and synapt_extract is absent.

The PEP 420 namespace move, package metadata, internal imports, resource fallback depth, docs/release substrate, preserved response-format names, and extract_batch skeleton now read clean. No remaining blocker. Approved to merge to sprint-39.
