refactor(grammar): staged recognition pipeline (ADR-0008) — 29 grammars to declarative PipelineGrammar - #32
Merged
Conversation
…Composer (S4)
Implements the hardest Money recognition strategy (ADR-0008 S4): a single
fused either-order regex that matches a currency lexicon token (symbol,
word, or alpha-3 code) adjacent to an amount in either order, emitting one
span-bearing RecognitionMatch per token.
- Add paxman/core/grammar/composer.py: AmountComposer stage builds the
fused regex in __post_init__ (LexiconAlternation for symbol/word, fixed
[A-Z]{3} for the code case) and emits notations via a caller-supplied
notation_fn + amount-shape classifier, guarded by a BoundaryGuard.
- Migrate Money code/symbol/word grammars from bespoke recognize() to
PipelineGrammar declarations using AmountComposer.
- Add tests/property/_legacy_money_grammars.py (verbatim legacy snapshot)
and test_money_grammar_parity to the Migration Proof Harness, proving
byte-identical RecognitionMatch parity (26 cases).
All 2517 tests pass; ruff, pyright (strict), import-linter clean.
…exStage (S3+S4+S5)

- ruff format on Phone grammars (international_00, national, tel_uri) and legacy snapshot - move development reports to docs/development/reports/
Fix review findings from parallel Oracle and thermo-nuclear audits of
ADR-0008 staged recognition pipeline (origin/main...HEAD, 64 files):
- Currency code_recognition: replace hard-coded lookaround literal with
BoundaryGuard.word_sign() composition (BoundaryGuard family D5, Thermo F-01)
and keep re import for re.Match typing.
- IPv6: use named capture (?P<addr>) instead of positional group(1) to
prevent future inner-group shifts (Thermo F-07).
- AmountComposer: make boundary required (remove _DEFAULT_LOOKBEHIND/
_DEFAULT_LOOKAHEAD dead fallback) so mis-wired Money grammars fail fast
instead of silently returning zero matches (Oracle F-05, Thermo F-05).
- PipelineGrammar: move pre short-circuit to immediately after pre stage only,
not after every stage, and early-return on whitespace-only input (Oracle F-07,
Thermo F-08).
- BoundaryGuard.ipv6_token: document as consuming anchor pair
(?:^|(?<=...)) rather than zero-width lookaround (Oracle F-03).
- Date US/European: document document-order vs legacy grouped-order change
from two finditer loops to single (\\d{4}|\\d{2}) alternation; engine sorts
by start so canonicalize() identical, direct recognize() now document-order.
Add harness tests test_us/european_date_document_order locking the new
contract and proving sorted multiset parity (Thermo F-03).
- Phone strip_separators: add unit coverage for plus=False branch
(fallback line) in all four Phone grammars (Thermo F-14).
All gates green: ruff check, ruff format, pyright 0 errors,
import-linter Capability independence KEPT, pytest 2763 passed 1 skipped,
coverage 95.81% (core 96%, capability 96%, engine 97%), generated data drift
checks pass.

Inline comments:
In `@docs/development/reports/architecture-review-2026-07-26.md`:
- Around line 142-153: The benefit statement for active_grammars incorrectly
claims that adding a grammar requires no method edit. Update the wording to
state that adding a grammar requires one dictionary entry in this property.
- Around line 176-181: Add language identifiers to every affected fenced code
block in the architecture review document, including the blocks listing paxman
directories and the additional referenced ranges; use text for plain directory
listings or the appropriate language where applicable.
In `@docs/development/reports/recognition-handling-library-research.md`:
- Around line 476-480: Update the recognition pipeline so Grammar.recognize()
produces span-bearing RecognitionMatch values, or establish an equivalent
source-map contract, and ensure RecognizedRep preserves start, end, and raw_text
alongside the notation. Do not let recognition reduce results to bare NotationT
values before this metadata reaches the engine, so uniform deduplication and
document ordering remain possible.
- Around line 494-500: Clarify the normalization contract across both documents:
in docs/development/reports/recognition-handling-library-research.md lines
494-500, either align the shared normalization seam with the current pipeline or
explicitly mark it as future migration; in HOW_TO_ADD_NEW_CAPABILITY.md lines
263-270, distinguish Country lookup-key normalization from emitted notation and
align Phone and ISBN guidance with the same ownership model.
- Around line 174-178: Revise the “Validation/formatting separation (F4)”
statement to qualify format() as purely presentation only for separator changes;
explicitly account for add_check_digit=True appending a Luhn digit to a 14-digit
IMEI, or remove the “purely presentation” characterization.
- Around line 456-457: Update the matcher comparison table to describe the
pinned matcher as selecting the “first verified candidate” rather than the “best
match per span,” preserving the surrounding ambiguity behavior and other table
entries.
In `@tests/property/test_grammar_stage_parity.py`:
- Around line 150-163: Remove the obsolete
test_curated_corpus_parity_placeholder, including its unconditional pytest.skip
and importability assertion. Also remove the unused CURATED_CORPUS definition,
since real parity cases are already covered by the per-capability lists; no
changes are needed to those existing cases.
In `@tests/unit/test_lexicon_alternation.py`:
- Around line 22-25: Update test_qualified_first_within_same_length to use two
equal-length tokens where one is qualified and the other is not, so
longest_first cannot determine the order and the qualified-first tie-break is
exercised. Keep the assertion verifying that the qualified token appears first.
In `@tests/unit/test_phone_helpers.py`:
- Around line 1-17: Apply the required pytest markers at both affected sites: in
tests/unit/test_phone_helpers.py (lines 1-17), import pytest and add
module-level pytest.mark.unit; in tests/property/test_grammar_stage_parity.py
(lines 928-956), decorate test_us_date_document_order and
test_european_date_document_order with pytest.mark.property.

502-513: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winClarify the normalization-layer ownership.
The paragraph identifies
Country/notation.py:normalize_nameas a notation-layer lookup transform, then broadly states that syntax normalization lives in the grammar layer. State the exception explicitly so future capability implementations do not move Country normalization into grammar code.Proposed wording
- syntax normalization lives in the grammar layer, semantic mapping in rules. + Country's normalize_name remains a lookup-key transform in notation; Phone + and ISBN keep syntax normalization in the grammar layer, while semantic + mapping remains in rules.🤖 Prompt for AI Agents

say it picks the first candidate accepted by the configured leniency, rather
than the first verified candidate; retain the distinction that POSSIBLE may
accept possible-but-invalid numbers and VALID is the default.
