dc1 full mirror REMOVED (D-135 amendment); dc-cache-proxy.sh now owns its net layer ...

Operator clarified intent, exact utterance: "DC0 is the test of a full mirror. DC1 is the test
of the mirror proxy. DC1 needed the partially created full mirror and associated
script/files/settings removed." Recorded as a D-135 AMENDMENT 2026-07-27 -- the per-DC split
is the DELIBERATE EXPERIMENT, not an interim state. That supersedes both the "PAUSED ... kept
dormant as the fallback" record and the "DC1's proxy is REPLACED by a full mirror afterward"
claim, which sat in THREE places (D-135, CURRENT-STATE:109, dc-cache-proxy.sh:6); all corrected.

dc0 FIRST (gated): sync re-run -> OK 2026-07-27T08:43:46Z ubuntu=0 uca=0 in 20s, confirming
the transient-500 diagnosis. The fixed check now reports PASS -- trustworthy precisely because
the same check FAILED on the same rack twenty minutes earlier. Stage 4 DoD bullet 5 is now MET
for both DCs (dc0 mirror PASS, dc1 proxy PASS), node-side half at G17.

WHY THE ORDER MATTERED. Asked to weigh rip-down-and-rebuild against surgical removal, the
rebuild path turned out to be BLOCKED, not merely slower: dc-cache-proxy.sh did not own its
utility net layer -- it REUSED dc-mirror.sh's <site>-mirror-net.service and refused to install
without it. So on dc1, whose ruled path is the PROXY, three files named dc1-mirror-* (net unit,
apply helper, resolved DNS drop-in) were load-bearing FOR THE PROXY. Consequences: the recorded
removal procedure would have silently killed the proxy, the bullet-5 PASS and the Stage-5 dc1
apt path; and the proxy could not be REBUILT afterward, since nothing but `dc-mirror.sh
install` created the net layer -- rebuilding a PROXY meant reinstalling the whole MIRROR
apparatus, enabled daily debmirror timer included. Operator direction: net layer first, then
rip it all down.

1. NET LAYER MOVED: <site>-cache-proxy-net.service + -net-apply + its own resolved drop-in,
   reusing dc-mirror's proven mechanism (bridge from the libvirt net NAME at runtime, hard
   rule 3). Proxy-named so a proxy-only DC has NO mirror-named dependency. Idempotent
   replace verbs, so both net units coexist safely where a site runs both -- dc0 unaffected.
   check asserts the ARTIFACTS, not just the live address/route: asserting only the live
   effect would PASS while the layer was really the mirror's, which is the exact failure.
   Harness 20/20 (was 15). T12 REPLACED not deleted -- it asserted the superseded design, so
   it failed by design; now inverted, plus T12b-T12f. T12b is scoped to non-comment lines on
   purpose: the header's account of the removed trap cites dc-mirror.sh install, and deleting
   that history to satisfy a grep would lose why the trap existed.
2. INDEPENDENCE PROVEN BEFORE DELETING: a oneshot with RemainAfterExit=yes does not undo its
   work on stop, so stopping the mirror unit would have proven nothing. Removed the live state
   outright (addr count -> 0, default route count -> 0), applied the proxy-owned unit ALONE,
   both restored; check dc1 PASS with dc1-mirror-net.service disabled.
3. WHOLESALE REMOVAL: all mirror units, timer, sync helper, nginx vhost, resolved drop-in, the
   debmirror package, and 330G of partial mirror (33,037 files, rm -rf 47.6s; disk 339G ->
   9.0G). Zero mirror-named residue, every proxy artifact present, proxy PASS throughout and
   never down. Capture docs/audit/dc1-mirror-teardown-20260727.txt.

nginx left installed deliberately: a mirror prereq, but with the vhost gone it is a generic
server on its stock default vhost; removing the metapackage while nginx-core runs is a
half-measure and a full purge is scope creep on a rack host.

Gauntlet ALL GREEN (81), repo-lint 0-fail, dc-cache-proxy 20/20, dc-mirror 24/24.

Revert: `dc-mirror.sh install dc1` (needs debmirror reinstalled) then `sync dc1` to re-pull
~950G; git revert dc-cache-proxy.sh + harness to restore the mirror-owned layer. The 330G
partial is NOT recoverable -- deliberately, per the amendment.

G17 opened by operator ruling; Stage 4 DoD bullets 5-6 repaired (DOCFIX-204) ...

RULING (GA-R5), 2026-07-27. Question as presented: "The node-side half of bullet 5. Nodes are
powered off by the READY-handoff ruling, so no node-side probe can run as things stand. Either a
gated rescue-boot check on one node per DC now (closes it inside Stage 4), or split it into its
own gate row targeted at Stage 5 first boot (GA-R6 E3 explicitly permits this; a conditional
close is not permitted)." Operator answer, exact utterance: "split it into its own gate row".
Recorded in the G17 row of docs/CURRENT-STATE.md (the authority); pushed before dependent work.

G17 "Per-DC artifact source reachable FROM A NODE", [V], OPEN. dc0 -> curl 200 from a booted
node against the D-135 item-1 mirror; dc1 -> apt fetches through the proxy at 10.12.68.4:3142,
since dc1's ruled path is the CACHING PROXY with no node-facing mirror (D-135 amendment) and
checking it as one fails by design. Trigger: Stage 5 first boot. The row states that G17 is NOT
a Stage-5 precondition -- Stage 5's bootstrap needs open edge egress for the juju agent stream
and snaps (D-135 items 2-3 unbuilt), a different path from the apt artifact source.

Stage 4 retains bullet 5's rack-side half: the source answers on its own address with an
attested-current sync. dc1's proxy PASSES; dc0 pends the sync re-run.

DOCFIX-204 -- bullet 6 was UNSATISFIABLE and its stale text had spread to four surfaces. "NTP
from the DC's own OPNsense edge working" is superseded by D-129(iv) (RULED 2026-07-21, "Keep
MAAS hierarchy", no NTP role on the edge): the DoD asked for confirmation the edge is the time
source, which the ruling had already refused, so a correctly-built DC could never meet it.
Repaired in the phase-3 DoD (bullet 6 struck, bullet 5 rewritten per-DC), the phase-3 Step 7
(REWRITTEN -- it branched on gap #5 that D-135 resolved, applied one mirror check to both DCs
which fails on dc1 by design, and asked for checks "from a deployed node" that the READY handoff
makes impossible), the workflow-doc Gate cell (which also still said "Nodes deployed",
contradicting DOCFIX-200), the buildout design, and the phase-4 prerequisites (same "nodes
Deployed" error -- exactly the expectation DOCFIX-200 removed to stop Stage 5 breaking).

phase-4 also gains a block making it the OWNER of G17's captures, warning that first boot is the
observation window and missing it forces a deliberate rescue-boot.

Text and gate-record only; no live state touched. repo-lint 0-fail. DOCFIX next-free -> 205.

Revert: git revert this commit; all changes are documentation and the G17 gate row.

Stage 4 close-out: fix dc-mirror.sh check false-greening the mirror gate ...

Operator directed closing Stage 4 before resuming the DC1 Stage-5 chain. Verifying the DoD's
fifth bullet ("per-DC mirror reachable") found that the check the gate would close on COULD
NOT FAIL.

scripts/dc-mirror.sh:271-273 tested `[ -f last-sync.status ]` and printed the file's contents
behind an unconditional "OK" -- the status word was displayed but never asserted on, so the
check exited PASS regardless. MEASURED on both racks:

- dc0 read "FAIL 2026-07-27T00:54:54Z ubuntu=255 uca=0"      -> printed OK, PASS
- dc1 read "RUNNING 2026-07-23T21:49:35Z", four days stale,
  left by the debmirror the D-135 amendment killed by signal -> printed OK, PASS

GA-R6 requires a stage to close on a NAMED executable check whose captured output the closing
commit cites. A check that cannot distinguish "synced" from "failed" or "died mid-run" is not
that check.

FIXED: the status word is case-analysed. OK* passes. FAIL* misses. An ABSENT file misses (it
was a passing `note`, but nothing has attested the content). An unrecognised word REFUSES
instead of defaulting to success. RUNNING* is deliberately neither pass nor plain fail --
in-flight and died-mid-run are indistinguishable from the file alone, so it reports an explicit
UNKNOWN and cross-checks the unit, naming a RUNNING marker with no active unit as a corpse.

Harness 19 -> 24; T20-T24 lock each status word and T24 locks out the return of the exact
defective shape.

PROOF, re-run against both live racks -- the gate is now honestly NOT MET for the first time:
dc-mirror check (dc0): FAIL / dc-mirror check (dc1): FAIL. Capture
docs/audit/stage4-mirror-gate-20260727.txt.

SUBSTANCE (measured, not inferred):
- dc0's mirror CONTENT is complete: 949G ubuntu + 342M cloud-archive, all three dists plus
  pool. Only the overnight INCREMENTAL failed -- "Download of dists/jammy/Release failed: 500
  read timeout" aborted the ubuntu leg with 255; the UCA leg succeeded. Transient upstream
  fetch failure, not mirror damage. Timer re-arms 2026-07-28 00:14:48.
- dc1's PROXY -- its RULED artifact path per the D-135 amendment -- checks PASS genuinely
  (apt-cacher-ng on .4:3142 serving archive + UCA Release 200). Its dormant fallback debmirror
  is dormant only ACCIDENTALLY: the timer is `enabled` with an EMPTY next-elapse because the
  unit sits in failed/Result=signal, so the ruling is enforced by nothing and a reset-failed
  would re-arm a 330G -> ~949G pull.

ALSO RECORDED, not yet actioned: DoD bullet 6 ("NTP from the DC's own OPNsense edge") is STALE
and unsatisfiable -- superseded by D-129(iv) 2026-07-21 ("Keep MAAS hierarchy", no NTP role on
the edge) -- and survives in four surfaces needing a DOCFIX before it can be checked at all.
The node-side half of bullet 5 needs an operator decision (gated rescue-boot check vs its own
gate row per GA-R6 E3); nodes are powered off by the READY-handoff ruling, so no node-side
probe can run as things stand. There is no conditional close.

No live state was altered: both racks were read only. repo-lint 0-fail, dc-mirror 24/24.

Revert: git revert the scripts/dc-mirror.sh + tests/dc-mirror/run-tests.sh changes; the check
returns to passing unconditionally on last-sync.

permission allowlist: 13 read-only entries; ssh/scp/virsh and creds-matrix DELIBERATELY excluded ...

Transcript scan of the 44 most-recent session JSONLs across both project dirs, counting Bash
command+subcommand pairs and splitting each candidate into LOCAL vs nested-inside-ssh (a
command that only ever runs inside `ssh host '...'` gains nothing from its own rule -- the
outer ssh is what the permission layer matches).

ADDED to permissions.allow only, 31 -> 44 entries. ask/deny/env/hooks untouched, nothing
removed or reordered, JSON re-validated and de-duplicated:
  bash scripts/creds-audit.sh * ; bash scripts/dc-dc-ceph-disk-budget.sh * ;
  bash scripts/site-baseleg.sh check* ; tofu validate* (+ -chdir variant) ;
  tofu state list* (+ -chdir variant) ; tofu state show* ; tofu providers schema* ;
  tofu version* ; ip route* ; systemctl is-active *

The substantive half of this change is what was NOT added:

- ssh (693 calls), scp (47), virsh (234) -- the three biggest prompt sources, left alone.
  They are this cloud's MUTATION TRANSPORT; CLAUDE.md hard rule 3 makes the ask rules the
  enforcement mechanism for per-mutation approval and says not to work around them, and the
  `Bash(ssh *)` disposition is an OPEN operator item queued at the 2026-07-23 close.
  Allowlisting any ssh shape would bypass the gate and pre-empt an unresolved decision.
  THIS COMMIT DOES NOT DISCHARGE THAT QUEUED PRUNE -- it is still open.
- python3 scripts/creds-matrix.py (76 local runs, the largest genuine miss) -- skipped
  because `Bash(*creds-matrix.py *--privileged*)` is an ask rule added 2026-07-26 right after
  the auto-mode classifier incident, and every prefix pattern wide enough to cover the
  observed `... 2>&1 | tail` forms would ALSO match --privileged. Allow-vs-ask precedence was
  not verified, and a rule that might silently downgrade an operator-installed gate is the
  class of change hard rule 3 forbids. Needs the precedence answer, then exact forms.
- tofu plan (54) -- read-only in effect, but CURRENT-STATE section 10 says in terms "Do NOT
  re-run `tofu plan` casually against live state". The prompt is deliberate friction.
- python3 -c/heredocs (324) and shells: arbitrary code execution. curl (114): mutation vector
  via -X/-d. tofu fmt (26): rewrites files. tofu init (10): mutates .terraform/. nft list
  (10): normally needs sudo, which correctly stays ask.

Flagged not fixed: six existing allow entries are redundant with Claude Code's built-in
auto-allow (git status/log, grep, ls, jq, cat scripts/*), and `Bash(git pull*)` sits in allow
though it is a fetch-and-merge. Removing entries was out of scope.

Folded into today's session changelog as item 6 (GA-R2/D1, ONE changelog per session) with a
per-item revert. repo-lint 0-fail; no executable surface changed, so the gauntlet result from
this session's earlier commit (ALL GREEN, 81) still stands.

Revert: drop the 13 appended lines from permissions.allow -- a contiguous deletion.

creds consolidation batch: SEC-021(b) dc0 power key, SEC-025 NetBox GUI, V2 ruled deferral ...

Operator asked whether vcloud holds a consolidated set of login creds for every account that
exists, and what is missing / needs creating / was never moved in. Audited, then cleared the
consolidation batch on operator direction ("clear the whole consolidation batch first").

The audit's own headline: creds-audit read CLEAN on all three sites while the matrix returned
13 findings -- and the two most consequential gaps were in NEITHER surface. They were found by
enumerating the accounts that ACTUALLY EXIST. Absence of a ROW is invisible to the register,
which generalises D-137's founding argument one level up.

VERIFIED POSITIVE (both previously only asserted):
- MAAS account set COMPLETE: all 6 live accounts accounted for; admin + operator passwords on
  vcloud, juju-vr1-dc0/dc1 random+unstored BY RULING with API keys present, MAAS +
  maas-init-node MAAS-internal.
- tier-3 V1 now MEASURES maas-admin-password byte-identical to the headend source-of-record,
  so SEC-020's stale-trap risk is clear as of this date.

DONE:
- dc0 SEC-012 power key consolidated to vcloud + .pub DERIVED (SEC-021(b) as written).
  MEASURED FIRST, because the naming looked like a defect and was not: the headend
  maas-virsh_ed25519 and the snap's id_ed25519 are the SAME key; it IS dedicated (distinct
  from the dc0 service key, which is what SEC-012 requires); and dc0 using the snap's default
  identity is SEC-016's RULED design. So no re-mint, no live power path touched.
- dc1 svc .pub backfilled to the headend store (public-key material, sha256-verified).
- NetBox web-GUI admin password consolidated -- a HUMAN login that had never left the VM it
  was minted on, the third instance of the SEC-009/SEC-020 miss class. SEC-025 OPENED for the
  at-rest exposure the copy CREATES, not the gap it closed. Open rows 20 -> 21.
- V2 taught the ruled-deferral state: SEC-006's standing "revoke at completion of this
  deployment" ruling is now ACKNOWLEDGED (still naming the credential live and exposed)
  instead of failing every run. Reissuing the token would have CONTRAVENED that ruling, so the
  register was what needed to change. Match demands the cased state word AND explicit operator
  ruling attribution, and cannot cross a ledger table cell -- T58/T59 lock the evasion out.
- Added --ledger (default unchanged): V2 read the register via --repo, which the harness must
  point at the real repo for S4, so V2 had shipped with ZERO harness cases. T56-T59 added.

Findings 13 -> 7. Matrix 82 rows, harness 60/60 (was 56), creds-audit CLEAN x3, gauntlet ALL
GREEN (81), repo-lint 0-fail. The register is NOT green and is not expected to be.

RESIDUAL, all recorded: dc0-edge-api x2 (the opnsense-api.txt re-mint is a live edge mutation,
deliberately EXCLUDED from this batch), S5 x3 (RULED by SEC-016 -- needs a ruled-exception
mechanism, operator decision), S6 conflation x1 (the SEC-020 defect), E4 x2 (Stage-5/6 rows).

LOGGED NOT ACTIONED (hard rule 1): no registered root/console credential at EITHER DC edge
(measured absence of row/manifest/SEC row; what those passwords ARE is UNKNOWN and
deliberately unprobed per hard rule 2 -- vector is the LAN-reachable GUI and serial console,
not SSH, which is key-only and proven); plus the two structural blind spots that let it hide
-- S5 compares only cardinality=per-DC while all six per-site rows are office1-only, and
vm-secret-locations declares no rack/edge/cloud/unit/client location though the checker
accepts them.

Revert: per-item reverts in docs/changelog-20260727-creds-consolidation.md. The headend, snap
and NetBox VM source copies were never modified, so every file move is reversible by deletion.
