Output gate step 3 now runs scan_secret_egress over every decoded base64
blob's plaintext, not only scan_lexicon. A base64-wrapped credential that
formerly vanished (decode fed the lexicon, which has no secret patterns)
now surfaces as decoded:egress:* carrying the blob offset. Evidence stays
length-only, so the decoded finding never leaks the secret value.
Hex-wrapped secrets remain a documented honest-limit (entropy exposes
decoded plaintext for base64 only). README honest-limits + CLAUDE.md
Kontekst updated; 3 tests added (347 passed, was 344).
A received OKF bundle MAY legitimately carry index.md (directory listing, read
first under progressive disclosure) and log.md (update history) at any level
(spec §3.1/§6/§7). import_bundle previously hard-rejected those basenames in the
T4 path gate, so a conformant third-party bundle was over-blocked in full
(FAIL_SECURE) — and because the reject fired before scan_concept, index.md's
body (the highest-priority injection surface) was never scanned.
import_bundle now defaults allow_reserved=True: reserved basenames are scanned
as structural files (path-safety checks — traversal / absolute / backslash / .md
— still apply). The shadow-reject (an *upload* masquerading as index.md) is
preserved: the front-end passes allow_reserved=False so a materialized upload
landing on a reserved basename is still refused. That front-end opt-in was
required to keep the shadow-reject once the default flipped (not in the plan's
Filer set; traced from the code).
- okf.py: validate_concept_path/_validate_concept/import_bundle gain the
keyword; validate_concept_path default stays False (strict standalone).
- tests: +3 (legit index/log admit; injection in index.md body caught;
okf_version frontmatter admits). Per-concept-iteration test switched to a
traversal vector; mode-b showcase's index.md surface reframed from
reserved-name-reject to index.md-body-scan.
- README honest-limits + CLAUDE.md context note the mode-b/upload distinction.
Suite: 341 -> 344 passed. Core invariant intact (dependencies=[]).
Close the EchoLeak wiring hole (CVE-2025-32711 class): markdown images/
links, reference definitions, autolinks, raw active HTML and data: URIs
now surface as report-only findings (active:*, OWASP LLM05) in
scan_output step 6, so screen_output and okf.import_bundle dispose of
them instead of admitting them with findings=[].
- new active_content.py: canonical home of the shared pattern table +
scan_active_content; neutralize refactored to import it (mutating API
and behavior unchanged, all neutralize tests pass as-is)
- images/links flagged only for absolute/protocol-relative URLs:
relative in-bundle links are legitimate wiki/OKF mechanism (principle 5)
- evidence carries defanged URLs only (hxxps://evil[.]example)
- EchoLeak vectors planted in both showcases; detach proofs cover them
- README export list + checklist step 6, CLAUDE.md context line updated
Suite: 321 -> 341 passed. Core invariant intact (dependencies=[]).
Concede the binary layer that survives text extraction as out-of-scope (a
shipped control): VBA/macros, OLE/embedded objects, OCR-needed image text,
font/render stego, encrypted files. Point to the two-stage OKF inbox showcase as
the worked example, and list the known gaps (.xlsx/.pdf deferred, .docx tables,
grouped .pptx shapes, numeric CSV -/+ FP).
Pre-release hardening from an independent adversarial review; each fixed
test-first (failing test -> fix -> green). 214 tests pass.
- entropy (M1): decode-and-rescan now runs BEFORE false-positive suppression,
so an SRI/media-prefixed injection blob is still decoded and lexicon-rescanned.
Suppression gates only the entropy finding, never the decode.
- output/disposition (M3): the invisible-carrier invariant now holds on the
persist gate. scan_output flags zero-width/BIDI presence and disposition
treats those + lexicon:unicode-tags-present as any-tier carriers, so a carrier
in model output fails secure even under a trusted policy.
- contract (M2): assert_credential_allowlist catches a bare <PROVIDER>_KEY
(e.g. STRIPE_KEY) that the old regex silently missed (fail-open). Deliberately
broad: also flags PARTITION_KEY/SORT_KEY as loud, allowlistable FPs -- fail-loud
beats fail-silent for an isolation control.
- disposition (m6): guard runs decide inside its guarded block -> total
fail-closed even on a malformed report.
- output (m4): egress placeholder suppression anchors word markers (example,
todo, ...) to a word boundary, closing a fail-open where a real secret merely
containing such a word was suppressed.

Mirror the badge convention from the ms-ai-architect plugin README — shields.io
STATIC badges (img.shields.io/badge/), which work on Forgejo where dynamic
build-status endpoints do not. Type-adapted for a library rather than a plugin:
the Platform slot becomes python-3.10+, the content-count slot becomes
tests-201-passing, plus an honest status-alpha badge.

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).
