Session-ledger summaries rotated 2026-07-29 (GA-R4 rule 3 / F1)

Moved VERBATIM out of docs/session-ledger.md to restore the 300-line cap when the 2026-07-29 close bookend was appended. Oldest-first, per GA-R4 rule 3. Nothing here is status: docs/CURRENT-STATE.md is the only status authority (GA-R1), and each summary below still points at its own archived full body.


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

  • D-137 was ADOPTED-not-built at open; all THREE tiers now exist plus enforcement (preflight P5 blocking). 17 commits af1b682..1696d08 pushed. Stage 4 stays OPEN; no stage closed.
  • Six-lens committee audited the build; FOUR converged on one root cause -- tier 2 keyed existence on host-role alone, ignoring site-key, so one site's credential satisfied every site, MASKING SEC-021's dc0 on-disk absence. 8 false greens, all reproduced and fixed.
  • Owned: ~21 inferred filenames (reported six); systemic sec-ref mis-attribution; CURRENT-STATE cited a verdict file for measurements it lacked. 2 claims WITHDRAWN.
  • Five operator rulings (GA-R5, quoted on D-137): 12-column schema; tier 1 as blocking P5; tier 2 local-blocking + stages-reached coupled by new repo-lint L12; tier 3 probe boundary; SEC-024 chmod. Ruling 4 (SEC-009 -> pointer) executed.
  • SEC-024 opened then remediated (mode), severity corrected first. SEC 19 -> 20. Ledger rotated twice (GA-R4 F1). Gauntlet 79 -> 81 GREEN; repo-lint 0-fail.
  • NEXT: live mission has NOT moved -- resume the DC1 Stage-5 chain per CURRENT-STATE. Unbuilt/unruled advice: creds-mint.sh BEFORE Stage 5 (largest minting event).
  • Full body: docs/archive/session-20260726-d137-build.md. Status ONLY in CURRENT-STATE.md.

SESSION CLOSE 2026-07-27 -- creds consolidation + STAGE 4 CLOSE-OUT (bounded, GA-R4)

  • Opened on a creds question; ended closing Stage 4. STAGE 4 IS CLOSED AND MERGED -- operator-gated merge commit 6f5701d on main (2 parents, not squashed, 77 commits), branch retired local + remote, post-merge gauntlet ALL GREEN (81) + repo-lint 0-fail on main, close recorded in CURRENT-STATE by 1023596. Next stage branches off main.
  • Creds: dc0 SEC-012 power key consolidated + .pub derived (SEC-021(b) as written -- measured first: it IS the dedicated key, and dc0 using the snap default is SEC-016's ruled design, so NO re-mint); NetBox GUI admin password consolidated (SEC-025, rows 20->21); dc1 svc .pub backfilled. Findings 13 -> 7. MAAS account set verified COMPLETE by enumeration.
  • V2 taught the ruled-deferral state -- reissuing SEC-006's token would have CONTRAVENED a standing 2026-07-13 ruling; the register was what needed changing. --ledger added; V2 had shipped with ZERO harness cases.
  • Two false greens fixed, both in controls that had passed for days: dc-mirror.sh check asserted last-sync EXISTED (dc0 FAIL, dc1 4-day-stale RUNNING both read OK); and creds-audit CLEAN x3 alongside 13 matrix findings. Lesson repo-carried in the skill.
  • Rulings (GA-R5, all quoted): G17 opened (node-side reachability split out -- powered-off nodes cannot be probed); SEC-024 retention "Keep both"; set-interface-v4 reload "a"; D-135 AMENDED (dc0 tests full mirror / dc1 tests proxy -- dc1's 330G mirror REMOVED, not paused).
  • DOCFIX-204: DoD bullet 6 was UNSATISFIABLE (D-129(iv) had ruled the opposite); 4 surfaces. Carve residue: 108 fabrics -> 17, cascade-checked. dc1 nginx purged.
  • OWNED: first draft of the pf reload sat inside the reconfigure heredoc -- would have fixed nothing in the very drop case that caused the bug. Caught pre-ship.
  • FINDING for the next session (logged, not actioned): tests/creds-matrix T24's finding-class baseline (expected-findings.txt) covers TIER 1 ONLY -- tier-2/3 classes (E1/E3/E4/V1/V2) have NO baselined red state, so a future false green there would not turn the gauntlet red. Same class as the two false greens this session fixed. Also still open from the D-137 close: creds-mint.sh is unbuilt/unruled advice and Stage 5 is the largest minting event, so it is worth ruling BEFORE the bundle deploy rather than after.
  • POST-CLOSE DURABILITY SWEEP (operator-requested): 4 transcript-only items landed on surfaces -- worst was dc-mirror.sh's dc1 row carrying NO warning that dc1 is proxy-only, so install dc1 would silently rebuild the removed apparatus + enabled timer + ~950G pull. Also: a WRONG causal claim in the mirror-gate capture superseded by appended correction (reset-failed cannot re-arm an inactive timer; the vector was a REBOOT via Persistent=yes); platform-traps section 5 added; the two-net-units coexistence claim marked REASONED-NOT- MEASURED. Capture docs/audit/queued-findings-20260727.txt. QUEUED: a runtime install guard for a non-mirror site (a comment is strictly weaker and prose-only prevention has already failed twice here).
  • Gauntlet ALL GREEN (81), repo-lint 0-fail. Full body: docs/archive/changelogs/changelog-20260727-creds-consolidation.md; stage record docs/archive/stage-records/vr1-stage4-record.md. Status ONLY in CURRENT-STATE.md.
