… stale "pinned" doc claims (BACKLOG #338) The engine's TLS key-exchange (KEX) groups are INHERITED from OpenSSL's default group list, not pinned to the approved set. harden_kex_groups pins nothing until SSLContext.set_groups lands in Python 3.15, so on every interpreter this project currently runs on the approved pin is inert. This is documentation accuracy plus observability -- it changes no live TLS behaviour (the TLS 1.2+ floor is the enforced control), and on a NOT-DEPLOYED beta there is no exposure today; the pin is a future 3.15 hardening. Two parts: 1. Report-only surfacing. New pure helper config/tls_policy.kex_groups_report() builds a throwaway probe context and asks the ONE authority, harden_kex_groups, what it manages to pin -- so the read-out can never drift from what the connectors actually do. It returns "inherited (...)" on a pre-3.15 interpreter and "pinned: ..." on 3.15+. Surfaced as an additive SecurityPosture.kex_groups field (str | None, default None), wired in create_app beside fips_attestation(), rendered as a status-page row in the web console beside the FIPS/OpenSSL rows. Report-only: it reflects, and changes, no TLS behaviour. 2. Three doc-accuracy edits correcting restatements that still read as "pinned": CONTAINER-EXPOSURE-EVALUATION.md (verification table), ASVS-L2-PHASE0-CHANGES.md (PQC roadmap row), and #200's Closes line in docs/archive/backlog/BACKLOG-CLOSED.md (11.6.2 annotated PARTIAL). Each links to PHI.md's data-in-transit section, the single source of record for the measured accepted set, rather than restating it. The two Python-3.15 tripwire tests in test_tls_policy.py that fire when set_groups/get_groups land are left untouched -- they are the signal to actually set the pin. Engine UI seam bumped 17 -> 18: the golden seam snapshot introspects SecurityPosture's field set, so a purely additive field trips the handshake; SUPPORTED_ENGINE_SEAMS and the golden snapshot updated to match. Tests: test_tls_policy.test_kex_groups_report_reports_inherited_today (the helper reports inherited + names the approved list, never "pinned:"); test_api_auth.test_security_posture_reports_kex_groups (the field flows through the MONITORING_READ-gated, audited posture route and matches the helper); a status-builder assertion that the console renders the row. All three falsified: blanking the helper reddens the two report tests (assert 'inherited' in ''); removing the console row reddens the status-builder test (assert 'key-exchange' in html).
Flip the #338 status banner from filed/not-started to shipped, now that the report-only kex_groups posture field and the three doc-accuracy corrections have landed. The banner records that the KEX groups are documented as inherited (the pin is inert until Python 3.15) plus the report-only surfacing behind engine seam v18. Banner line only, under the #338 heading, verified by number. The ranked table, the four census distribution lines, and every other item's banner are untouched. The census was NOT recomputed.

Fixes BACKLOG #338. Adds a REPORT-ONLY TLS kex_groups posture field, 3 doc-accuracy edits, and
bumps the webconsole seam.
⛔ THIS PR OWNS THE SEAM BUMP:
_ui_seam17 -> 18 andSUPPORTED_ENGINE_SEAMS{17} -> {18}. Theseam is a SINGLE INTEGER, so if any other pending PR also bumped it the two could not both land
unrebased. No other branch in this campaign bumps it, and this PR is deliberately sequenced LAST so
the bump lands on top of everything else rather than forcing rebases beneath it.
Report-only by design: it surfaces posture without enforcing it.
({18} == 18) must be run FROM THE WORKTREE'S OWN CWD. A --rootdir-only run imports a DIFFERENT
worktree's messagefoundry package and false-fails on the new symbol -- a red result caused by the
harness rather than the code, which is the same class as a green result caused by the harness.
VERIFIED: engine-side 140 passed, console render 2 passed, seam coherence confirmed.
