SESSION CLOSE 2026-07-26 -- D-137 build + committee audit + remediation (GA-R4) ...

Bounded 15-line summary in docs/session-ledger.md; full body archived to
docs/archive/session-20260726-d137-build.md in this same commit (GA-R4
rule 2). Status remains CURRENT-STATE.md's alone (GA-R1).

GA-R4 F1 cap handled as designed: writing the close summary took the ledger
to 300 against the 300-line cap, so the next-oldest summary rotated out --
a long session forces older summaries out rather than being truncated
itself. Ledger 280/300, close summary 15/15.

GA-R7 memory review: the creds-folder-convention entry asserted the D-137
matrix was NOT BUILT, which this session falsified. Corrected, and the
reasoning-trap half kept (creds-audit CLEAN is still not evidence of
completeness, because absence is invisible to a declaration-based sweep).
Memory index line updated to match.

Stage 4 stays OPEN; no stage closed by this session. The live mission did
not move -- the DC1 Stage-5 chain is where it was at session open, and the
next session resumes it per CURRENT-STATE.

Gauntlet ALL GREEN (81), repo-lint 0-fail, ledger-scan exit 0.

session-ledger: rotate oldest-first to restore the GA-R4 cap (413 -> 280) ...

The live ledger was 413 lines against GA-R4's 300-line cap, a breach the
2026-07-25 close recorded as OWED and did not perform.

Rotated oldest-first as amendment F1 specifies: the eight summaries from
2026-07-18 through the fifth 2026-07-21 session moved VERBATIM to
docs/archive/session-ledger-rotated-20260726.md. Sessions from 2026-07-22
onward stay live. Nothing lost -- 8 moved + 8 remain = the 16 that were
there, and each rotated summary still points at its own archived full body.

TIMING: F1 binds the cap at session close; this was done mid-session at
operator direction, which is early rather than late. Rule 3's protection (an
open session's in-flight section is never rotated) is not implicated -- this
session has no in-flight section in the ledger.

Machine-derived block re-seeded from a fresh scan; fences intact. It had gone
stale: open SEC rows 19 -> 20 (SEC-024), next-free D 137 -> 138.

A status CLAIM corrected to narrative per GA-R4 rule 5: the 2026-07-26
addendum asserted D-137 implementation was "UNBLOCKED, not started" and
directed a fresh session to build it -- both falsified by this same session
hours later. Marked superseded and repointed at CURRENT-STATE, with the
original kept as the record of where that session stood.

Gauntlet ALL GREEN (80), repo-lint 0-fail, ledger-scan exit 0.
