Two consumers measured the 0.3.1 URL-shape rule against real corpora on the
same day. Record what they found, and pin the dispositions both of them
inferred wrongly.
Percent-escape FP: zero occurrences across both corpora (0/347 external URLs
in a 527-document vendor-docs corpus, 0/81 in a capture store). This bounds
the shape rather than closing it -- a consumer that slugs filenames from
titles produces %20 systematically, and that corpus is still unmeasured.
Query FP: the over-block that actually occurs. The two corpora hit disjoint
benign populations -- 16/16 publisher-authored utm_* tracking versus 35/35
content identity (?v=, ?channel_id=) where the parameter IS the resource.
An allowlist keyed on tracking-parameter names resolves the first entirely
and the second not at all, so no parameter-level remedy covers both. That
is input to the 0.4.0 axis-separation scope, not a fix here.
Both consumers reported dispositions they had inferred rather than run, and
both were wrong: a query-carrying link is MEDIUM, so it is held or warned,
never hard-failed. tests/test_wiring.py now pins that, plus the active-tag
gate -- counting raw HTML tags overcounts what the gate flags, since
formatting markup is inert and only name/on*=/URL-attr tags are active.
593 passed.
Module 11 (final) — the top-level wiring. The library never makes the model call
(no SDK imported by the core), so the public surface is the toolkit plus two
library-side bookends around the caller's tool-less transform (Form 1, chosen
with the operator over an export-only toolkit and a full orchestrator — the
bookends fit existing pipelines with least friction, encode the two halves the
library can stand for, and impose no control flow):
- prepare_input(text, source=INPUT) -> PreparedInput(fenced, nonce, report):
§6 steps 1-2, sanitize THEN fence (carrier can never smuggle a forged
delimiter). Merged report carries both steps' findings; renders no disposition.
- screen_output(text, policy, *, provenance, transform_failed) -> DispositionResult:
§6 steps 6-7, scan_output under guard() so a scanner error fails CLOSED
(FAIL_SECURE, never a silent persist). transform_failed routes the compound
forced-fallback rule.
- __all__ exports the full framework-agnostic surface: detectors, result types,
disposition machinery + presets, contract asserters, the grounding seam.
Docs: README refreshed from the stale "brief / pre-implementation" line to a v0.1
alpha status with a Form-1 quickstart, the §6 adopt-this checklist, and an honest
-limitations section (structural unsolvability at the text layer; semantic
poisoning invisible to lexicon+entropy; text-only, no multimodal). CHANGELOG
seeded; CLAUDE.md remote/status lines corrected (remote IS set, no longer
brief-stage).
10 wiring tests (public surface, prepare_input compose, screen_output fail-closed
+ compound). 189 green (showcase + corpora follow).
