SESSION CLOSE 2026-08-02 (part 2, GA-R4 bookend): queued backlog cleared, mirror root-caused, D-139 step 6 EXECUTED ...

DURABILITY TRIAD, MEASURED: vcloud 0 uncommitted / 0 unpushed; voffice1 SYNCED (was 1
behind -- it is the D-128 Plane-2 host where preflight runs); dc0 rack ~/repo-stage all 13
tracked files MATCH the repo, so the D-138 deploy client is in sync. That last check is the
one that caught the stale VIP overlay at the previous close.

GATES, quoted: repo-lint 0 fail / 1 warn (legacy D-001..018 ASCII carve-out); run-tests-all
GAUNTLET: ALL GREEN (98 harnesses), 97 -> 98 for the one harness added with its manifest
recorded deliberately; ledger-scan 3 open decisions, 28 open SEC (none opened this session),
next-free D-141 / DOCFIX-208 / BUNDLEFIX-053. RECONCILED: DOCFIX 207 -> 208 matches the one
number assigned; SEC unchanged at 28 matches zero rows opened; manifest 97 -> 98 matches the
one harness added.

WHAT THE SESSION DID: closed sweep F1 (rack deploy input re-staged) and F6 (maasdb proven
uncorrupted by a full-table pg_dump); diagnosed then ROOT-CAUSED F2 -- one of nine
archive.ubuntu.com backends hangs on a single dep11 object while serving its siblings, the
resolver rotates, 11/12 fetches succeed, and apt is unaffected because it fetches the .xz;
graduated F3/F4/F5 to platform-traps and script-authoring; assigned DOCFIX-207; and EXECUTED
D-139 step 6 -- 26 GUA VIP addresses created, 26 ULA addresses + 9 prefixes deprecated,
nothing deleted, plus 4 of 5 MAAS ULA subnets removed with the fifth HELD because it carries
the juju controller's and the MAAS region's only recorded v6.

CLOSE SWEEP: docs/audit/queued-findings-20260802-step6-queued-items.txt -- SIX FIRST
SURFACE, each grep-proven absent from every repo surface first. Highest-consequence: a broad
Bash(ssh vr1-dc0-maas *) allow rule in gitignored state, and -- found by tracing consequence
-- four destructive MAAS deletes that matched NO ask rule, because the committed rules pin
the `maas admin` profile and the double-quoted form while this session used
`maas vr1-dc0-region` in single quotes. Consent was given separately, so nothing was
bypassed, but the GATE did not fire; same rule-fails-to-MATCH class as the 2026-07-30 DHCP
cutover, now RECURRING rather than one-off.

GA-R7 MEMORY REVIEW: CLEAN -- zero entries claiming operator policy, priority or posture.
One update: instrument-currency gains instance THIRTEEN, a new shape (a comparison that
could never match, returning a clean ZERO) plus the meta-lesson that writing the rule down
does not inoculate against it -- three checkers that could not fail shipped in the same
session that landed the rule, and none was caught by re-reading my own work.

LEDGER ROTATED (GA-R4 rule 3): 294 lines would have breached the 300 cap; the TWO oldest
closed summaries moved VERBATIM to docs/archive/session-ledger-rotated-20260802b.md; ledger
now 287. No orphaned session -- rule 7 is a no-op. NO STAGE OPENED OR CLOSED; Stage 5
remains OPEN and this is a session bookend.

NEXT SESSION'S FIRST ITEM: the preflight-P2 / phase4 machines-overlay asymmetry -- P2
validates a merged input the deploy never passes -- then the bundle deploy.
