Reframe .pdf from a 'known gap'/TODO to a deliberate concession across the
honest-limits and OKF-upload docs. A top-level .pdf drop is already refused as
an unsupported format (inbox_frontend.py raises on the else branch), not
half-scanned; adding a PDF parser + reportlab (solely to author white-on-white
test fixtures) is disproportionate for a dev-scoped showcase, and the OCR /
font-render stego carriers a PDF would smuggle are out of scope regardless.
- README honest-limits: .pdf = concession, not TODO; only the numeric CSV FP
remains a known gap.
- docs/PLAN.md: upload table .pdf row marked 'conceded'; honest-scope paragraph
names .pdf; assertions tightened to 'every accepted format'.
Closes the last format gap before v1.0 freeze (Session G). No code touched;
357 tests green.
Replace the unverified/absolute novelty statement with the defensible
four-part-contract form, verified against a focused adversarial PyPI+GitHub
survey (2026-07-15):
- BRIEF §11: 'assumed, not verified' -> verified survey with sources. Names
aig-guardian (real, query-time; blurs only the minimal-dep-library
differentiator), GuardLLM (nearest neighbour, runtime hardening, no
scan-before-persist / capability isolation / fail-secure), and ipi-scanner
(orphaned placeholder repo, recorded for honesty not as prior art).
- README: differentiator moved from 'library vs hosted/model' to the full
four-part write-time contract.
- PLAN §27-31: drop the unverifiable 'the first' superlative.
Also promotes the v1.0 session plan (PLAN-v1.md) and the cross-model review
(review-2026-07.md) into docs/ on the open/ mirror, referenced by PLAN.md's
re-sequencing addendum.
Ground-truth pass over the named flagship consumer (portfolio-optimiser's
'OKF-upload-inbox') found it does not exist as a seam: both optimiser siblings
are frozen at release, carry their own OKF layer, receive no external bundles,
and take no dependency on this guard. Defer consumer integration (stream 2)
until the guard is mature; mature it here first, Node-port-friendly. Next
concrete build is the in-repo OKF inbox showcase (mode-b import_bundle as a
receive/quarantine gate), spec'd under 'The OKF inbox showcase'.
One realistic content sample carrying many vulnerabilities at once, run through
a mock ingestion pipeline (sanitize -> lexicon+entropy+decode-rescan -> output
gate -> disposition); assert every planted vuln is caught and disposition fails
secure. Doubles as the README worked example. Added to build-order step 11 and
the test strategy; tracked as task #11. Inspiration: llm-security/examples/*.
