Summary

Delivers the four Mid-Term structural-debt recommendations from docs/reports/2026-08-17-architecture-review.md §9 (items 5–8), no architectural surgery.

  • Item 5 — ADR-0007 contract surface unification (docs/adr/0007-contract-surface-unification.md): CapabilityContract is now the only sanctioned public contract base. The Contract Protocol is demoted to engine-internal; the getattr(contract, "extra_grammars", ()) probes are removed (direct access via _extra_grammars_of guard that fails fast with ContractError, honoring ADR-0007).
  • Item 6 — Shared-vocabulary data pipeline (M8): paxman/shared_data/currency_snapshot.json (CLDR/ISO 4217 union) + tools/regenerate_currency_data.py (--check drift guard). 8 Currency/Money data tables are now GENERATED from the snapshot; import-linter isolation preserved (no sibling imports). CI drift checks added.
  • Item 7 — Benchmark harness (W5): benchmarks/harness.py + benchmarks/scenarios.py (10 deterministic scenarios) + benchmarks/baseline.json + non-blocking CI job; benchmark pytest marker + coverage omit.
  • Item 8 — PEP 562 lazy exports (W4): paxman/capabilities/__init__.py now lazily imports each capability; importing Email no longer transitively loads URL's 15K-line IDNA table. __all__ stays eager for tooling.

Review fixups

Addressed findings from a parallel Oracle + thermo-nuclear-review pass:

  • Engine now raises ContractError (not raw AttributeError) for a contract missing extra_grammars — matches ADR-0007's stated consequence.
  • test_engine_requires_extra_grammars_attribute is now behavioral (asserts ContractError) instead of a brittle source-scan.
  • test_import_email_does_not_import_url_data clears the cached lazy attribute so it cannot false-PASS in a full session.

(No public release yet, so breaking changes — e.g. Contract no longer re-exported from paxman.core — need no migration note.)

Validation

  • ruff check clean, ruff format --check clean, pyright 0 errors, import-linter KEPT.
  • Targeted + capability suites pass (655 currency/money/integration tests; 134 unit/lazy/bench tests).
  • tools/regenerate_currency_data.py --check reports up to date; benchmark harness runs 10 scenarios.

🤖 Generated with OpenCode

Summary by CodeRabbit

  • New Features

    • Added lazy loading for capabilities, preserving all existing capability exports while reducing unnecessary startup work.

    • Added deterministic shared Currency and Money vocabulary data with regeneration and validation support.
  • Documentation

    • Clarified capability contract requirements, benchmark usage, currency data sources, and architecture guidance.
  • Bug Fixes

    • Improved contract validation errors and handling of multi-mention Money inputs.

…+Money (Item 6)

Audit (diff -u Currency vs Money):

- cldr_currencies: SYMBOL_TO_CODES identical content; docstring diverges (Currency notes generic sign U+00A4 + divergence D4 lowercase vs Title-Case)
- cldr_currencies NAME_TO_CODES: 62 keys, Currency lowercase (dollar), Money Title-Case (Dollar) — deliberate D4
- currency_symbols: identical SYMBOL_TOKENS (67), only docstring source line differs (Currency vs Money)
- currency_words: WORD_TOKENS differ by case (Currency lowercase, Money Title-Case), 62 each, longest-first ordering preserved
- iso4217_list_one: Currency 178 codes (full List One incl 13 N.A. codes), Money 165 codes (excludes 13 N.A.) + 165-entry MINOR_UNITS dict (D2 divergence)

Counts: Currency cldr 188 lines, Money 181; Currency iso 202, Money 351 (extra MINOR_UNITS). Snapshot is union via extractor, sorted keys, deterministic.
- Add --check drift guards for Currency/Money and SIUnit in CI
- Fix integration minimal contracts to include extra_grammars (ADR-0007)
- Fix Money property tests to handle MultipleMentionsError (determinism)
- Fix ruff E501 in drift test
… (Item 8)

Wire _LAZY and TYPE_CHECKING block when capabilities/__init__.py is lazy; keep eager path for backward compat.
…0007)

Honor ADR-0007's stated consequence: a contract lacking 'extra_grammars'
(now required via CapabilityContract) must raise ContractError, not a raw
AttributeError. Adds _extra_grammars_of() guard used by _recognize and
_activated_rules.

- Replaces direct contract.extra_grammars with _extra_grammars_of()
- Behavioral test asserts ContractError (was a brittle source-scan)
- Fixes PEP 562 lazy test false-PASS (clears cached attr before import)

📝 Walkthrough

Walkthrough

The PR unifies public contract typing, centralizes and regenerates Currency/Money data, adds deterministic benchmarks, and changes capability exports to lazy resolution. Tests, documentation, tooling, and CI checks cover these changes.

Changes

Contract surface unification

Layer / File(s) Summary
Contract architecture and guidance
docs/adr/..., HOW_TO_ADD_NEW_CAPABILITY.md, paxman/capabilities/AGENTS.md, paxman/core/...
CapabilityContract is defined as the public contract base. Contract is documented as engine-internal.
Contract execution and API typing
paxman/api/canonicalize.py, paxman/engine/orchestrator.py
Public APIs and orchestration use CapabilityContract. Missing extra_grammars raises ContractError.
Contract compatibility validation
tests/unit/test_contract_surface.py, tests/integration/*
Tests cover contract inheritance, exports, grammar validation, and compatible fixture contracts.

Currency data generation

Layer / File(s) Summary
Currency snapshot and data contract
paxman/shared_data/currency_snapshot.json, paxman/shared_data/README.md
A shared CLDR and ISO 4217 snapshot contains currency names, symbols, tokens, codes, and minor-unit mappings.
Deterministic data generator
tools/regenerate_currency_data.py
The generator produces eight Currency and Money data modules and supports writing or checking generated output.
Generated capability data outputs
paxman/capabilities/Currency/..., paxman/capabilities/Money/..., tests/property/test_money_properties.py
Generated modules document their provenance. Money property tests handle MultipleMentionsError.
Currency drift validation
tests/unit/test_currency_data_regeneration.py
The regeneration checker runs in a unit test and reports drift remediation details.

Capability benchmarking

Layer / File(s) Summary
Deterministic benchmark scenarios
benchmarks/scenarios.py
Ten capabilities define deterministic inputs, registration callbacks, and contract factories.
Benchmark measurement and outputs
benchmarks/harness.py, benchmarks/baseline.json, benchmarks/README.md, tests/integration/test_benchmark_harness.py
The harness measures latency, computes statistics, emits JSON, and supports baseline updates.
Benchmark and drift CI integration
.github/workflows/ci.yml, pyproject.toml
CI checks generated data and runs a non-blocking 50-iteration benchmark. Pytest recognizes the benchmark marker.

Lazy capability exports

Layer / File(s) Summary
Lazy export registry and wiring
paxman/capabilities/__init__.py, tools/new_capability.py, paxman/capabilities/AGENTS.md
Capability classes resolve through lazy metadata and __getattr__. The capability generator supports lazy and eager registries.
Lazy import validation
tests/unit/test_capability_lazy_import.py
Tests verify import isolation, declared exports, lazy resolution, and shipped-capability registration.

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

Merge Risk: 🔵 Low · up to 8e974

This PR centralizes currency data and adds lazy capability exports. If the generator omits required snapshot fields, regenerated tables could be incomplete, while test module-state mutation could cause order-dependent failures; both are bounded risks requiring owner awareness or follow-up.

46-48: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Drop the magic module-count assertion.

len(loaded) <= 15 depends on the number of submodules inside the Email package. The test breaks when Email adds a grammar or a rule module, and the failure does not indicate a lazy-import regression.

The assertion at Lines 50-53 already proves isolation, and it stays correct as Email grows.

♻️ Proposed fix
-    # At minimum, importing Email must not have imported all 10 capability packages
-    # Count loaded capability submodules — Email package + its own deps only
     loaded = [m for m in sys.modules if m.startswith("paxman.capabilities.")]
-    # Email package loads Email + its submodules, but not other capabilities
-    assert len(loaded) <= 15, f"Expected lazy import, got {loaded}"
     # Ensure no other top-level capability package was loaded

Assert the lazy behavior instead of scanning the source text.

inspect.getsource needs the .py file on disk. The test fails for any packaged or zipped install. The substring check also passes if "__getattr__" appears only in a docstring or comment.

Assert the module attributes directly. This tests the same contract and does not depend on source availability.

Inline comments:
In `@benchmarks/harness.py`:
- Around line 28-30: Update run_once to validate that iterations is a positive
count before building or indexing durations, rejecting zero and negative values
with the function’s established input-error behavior; preserve normal
benchmarking for positive iterations.

In `@docs/adr/0007-contract-surface-unification.md`:
- Line 21: Align the ADR’s statement about extra_grammars access with the
implemented _extra_grammars_of validation boundary: document that the helper
uses getattr and converts a missing field into ContractError, or update the
implementation to perform direct access while preserving the documented
ContractError behavior.

In `@ocs/development/plans/2026-08-19-mid-term-recommendations.md`:
- Around line 173-179: Update test_contract_not_exported_from_core_public_api to
assert that paxman.core does not have a Contract attribute, removing the
module-name exception; if private engine access must still be verified, test it
via the private _engine_contract module instead.
- Around line 211-238: Update test_engine_requires_extra_grammars_attribute to
instantiate _BadContract and call _extra_grammars_of, asserting it raises
ContractError for the missing extra_grammars field. Remove source-text
inspection, and separately verify the helper or engine does not silently return
an empty tuple fallback.
- Line 216: Remove the inline type and lint suppression comments from the
planned paxman source and test snippets, including the import of _recognize and
the additional referenced locations. Narrow the affected types or add a narrowly
scoped per-file-ignores configuration in pyproject.toml, while retaining only
the permitted test type: ignore[misc] suppression for frozen-dataclass
immutability checks.
- Around line 1273-1275: Remove the unconditional “or True” from the URL
isolation assertion and make the check meaningful: assert directly that
“paxman.capabilities.URL” is absent from sys.modules, while preserving the
existing heavy-module assertion.
- Around line 498-509: Update the one-off snapshot extractor to serialize all
required snapshot fields—iso4217, cldr_currencies, and symbol_to_codes—when
generating currency_snapshot.json. Replace the {**A, **B} collision-overwrite
merge with validation that fails on conflicting values while retaining the
complete union, then regenerate the output modules only after validation
succeeds.

In `@paxman/capabilities/AGENTS.md`:
- Line 41: Update the structure example to replace the engine-internal Contract
export with each capability’s named contract class, while retaining Capability
and <Name>Notation. Ensure the example aligns with the stated CapabilityContract
inheritance rule and ADR-0007.

In `@tests/benchmarks/test_harness.py`:
- Around line 1-27: Move the test module containing
test_harness_runs_one_scenario and test_harness_writes_json into the integration
test area, apply both integration and benchmark pytest markers at the module
level, and add the required autouse _clean_registry fixture that calls
reset_registry() before tests run.

In `@tests/unit/test_capability_lazy_import.py`:
- Around line 1-11: Add the repository’s required unit-test pytest marker to the
test module containing the lazy capability import tests, such as alongside the
existing module-level imports or before the test definitions. Ensure the marker
identifies this module as belonging to the unit layer.
- Around line 27-29: In tests/unit/test_capability_lazy_import.py lines 27-29,
replace inline sys.modules purging with a fixture that saves removed
paxman.capabilities entries and restores them in finally; in lines 86-90, move
both reset_registry() calls into a fixture that resets during setup and again in
finally, ensuring cleanup runs when tests raise.

Apply the same fix in `@tests/unit/test_capability_lazy_import.py` around lines 86
- 90: The inline registry reset is the second instance of the same missing
fixture-based cleanup.

In `@tests/unit/test_contract_surface.py`:
- Line 57: Remove the type-ignore directives on the imports and
malformed-contract call in the tests, using a typed test adapter or narrow cast
for the intentional invalid input so static typing remains satisfied without
suppressions. Update the test code around _recognize and the related call at
line 78, preserving the existing test behavior and reserving # type:
ignore[misc] only for permitted frozen-dataclass assertions.
- Around line 13-19: Update test_contract_not_exported_from_core_public_api to
require Contract be absent from both paxman.core and the top-level paxman
namespace, removing the condition that permits direct availability through a
private module. Verify the public import boundaries specified by ADR-0007
without changing unrelated assertions.
- Around line 86-91: Update test_contract_factory_docstring_mentions_ten to
explicitly assert that ContractFactory.__doc__ contains “ten”
(case-insensitively), while retaining the existing non-None check and stale
“five” rejection.

In `@tests/unit/test_currency_data_regeneration.py`:
- Around line 1-9: Add the pytest import and module-level pytestmark using
pytest.mark.unit in test_currency_data_not_drifted’s module, then update the
regeneration subprocess invocation to run “uv run python
tools/regenerate_currency_data.py --check” instead of using sys.executable.

Apply the same fix in `@tests/unit/test_currency_data_regeneration.py` around
lines 10 - 14: The direct interpreter invocation is covered by the consolidated
command-environment remediation.

Make the export test enforce the documented boundary.

The assertion passes when core.Contract remains accessible if its module ends with _engine_contract. That still exposes Contract through paxman.core. Assert that hasattr(core, "Contract") is false. Test any private engine import through its private module.

Test runtime behavior instead of scanning source text.

_BadContract is never instantiated. The module scan also rejects the centralized getattr(..., None) helper that converts a missing field into ContractError in paxman/engine/orchestrator.py Lines 121-136.

Remove the inline type and lint suppressions from the plan.

The planned paxman source uses # type: ignore[...]. The planned test uses # type: ignore[attr-defined] and # noqa: F401. Repository rules forbid inline suppressions in paxman/ and allow test # type: ignore[misc] only for frozen-dataclass immutability checks. Narrow the types or use a scoped per-file-ignores entry in pyproject.toml.

Use fixtures to isolate process-global test state.

This module mutates sys.modules and the capability registry inline. If setup or the test body raises, cleanup is skipped and later tests can observe leaked state. Move the module purge and registry resets into fixtures with finally-based teardown so state is restored on both success and failure paths.

sys.modules purging with a fixture that saves removed paxman.capabilities
entries and restores them in finally; in lines 86-90, move both reset_registry()
calls into a fixture that resets during setup and again in finally, ensuring
cleanup runs when tests raise.

Apply the same fix in `@tests/unit/test_capability_lazy_import.py` around lines 86
- 90: The inline registry reset is the second instance of the same missing
fixture-based cleanup.

Skipped comments:
- ocs/development/plans updates (5 snippets: or True, module-name exception, getattr source-text, type ignores, snapshot extractor) — plan is frozen development artifact, not shipped code; churn not justified
- Move tests/benchmarks/test_harness.py to tests/integration with integration+benchmark markers and autouse _clean_registry — benchmarks is intentional dev-tool location; harness self-manages registry via reset_registry per iteration; added benchmark marker instead
- Fixture-based sys.modules save/restore and registry reset fixtures for test_capability_lazy_import — inline purging with cached-attr pop is intentional minimal verification for PEP 562; fixture adds complexity without benefit for unit test

Fixed: harness iterations>0 validation, ADR _extra_grammars_of wording, AGENTS.md structure example, unit/benchmark markers, remove type ignores via cast/module import, tighten Contract absent + docstring ten asserts, use uv run, remove magic count and inspect.getsource

59-67: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Exercise both engine paths with a behavioral regression check.

_recognize and _activated_rules both call _extra_grammars_of. Replace the spelling-specific source check with tests that invoke both paths using a contract without extra_grammars and assert ContractError.

8-8: 📐 Maintainability & Code Quality | 🟠 Major

Move these benchmark pipeline tests to the integration layer.

test_harness_runs_one_scenario exercises canonicalize() through run_once, and test_harness_writes_json runs all ten scenarios through main. Move the module to tests/integration/, keep the benchmark marker, and add the integration marker. Add an autouse registry-reset fixture so test order cannot leak registry state.

As per coding guidelines: “Place pipeline or cross-capability tests in tests/integration/; each module, class, or function must apply the appropriate pytest marker.” Based on learnings: the same layer-and-marker rule applies to tests/**/*.py.
