Live console/framebuffer stack has zero dirty-region or heat/decay instrumentation (grepped framebuffer.c/vt100.c/console.c). True prerequisite is item 1.11 (dirty-event granularity), still unstarted, not 'the framebuffer work' generally, which has since shipped. Left open.
Traced every loop's actual firing cadence from source. Headline finding: the fleet-capacity loop (vm_physics_heartbeat_tick, the exact mechanism §22.4 cites as precedent) shares a global counter fed by every live VM, so with Tripod's real multi-VM topology it can fire faster in wall-clock terms than any single VM's own heat-inference loop -- the opposite of §22.4's required ordering. STADIUM_CAPACITY_TICK, the Kconfig symbol §22.4 specified as the fix, exists but is never read anywhere. Reported, not fixed; left open for Captain Bob's call.
Hermes v1's real message struct (init.4th blocks 4100/4105/4143) is 72 bytes with an out-of-line pointer+length payload, not the speculative 64-byte-cell/32-byte-inline-payload scheme from FABRIC.md §23.3. The design question is moot: the implementation went a different direction.
Verified via tools/kconfig/conf + kernel_amd64_defconfig: a .config edit to CONFIG_SK_PARITY_DEBUG genuinely flows through to the parity.c compile line's -D flag in both directions. Required installing bison/flex, which were missing.
Investigated 2026-08-13: not just the encoding field -- blk_get_meta()/
blk_set_meta() and the whole blk_meta_t on-disk layout have zero callers.
Captain Bob's ruling: flag and leave as-is, expected to be consumed once
Artemis's design (content-typed/owned/ACL'd blocks) is completed. No
code changed.

No code change; closed as investigated and ruled not-a-bug (deliberate
future-milestone scaffolding) rather than left open as a loose TODO.

Investigated 2026-08-13: confirmed unreachable by repo-wide grep, but
each of the three stubs is a real doc-commented placeholder for a future
per-arch MMU milestone, not leftover cruft. Captain Bob's call: leave in
place, keep tracked as a TODO rather than delete or wire in a no-op call
site. No code changed.

Punch list §C item complete. Corrects this morning's "structurally
excluded" framing -- the Hera-is-root case was reachable via
S" Hera" KILL, fixed in db66406. Broken-parent-chain half remains
genuinely unreachable and is no longer tracked as open.

Punch list §B item complete. Full read of capsule_vm_physics.c plus a
worked example show the touch()-fan-out truncation FABRIC.md §20.2
blamed cannot cause conservation drift -- vm_physics_transfer() moves
matched amounts on both sides of every call. Git history rules out a
since-fixed bug: the code predates §20.2's correction unchanged.
The one path that can genuinely drop heat is vm_physics_retire()'s
guarded no-valid-root case, structurally unreachable today (Hera can't
be killed, parent chains can't corrupt). Tracked as its own item in §C.

Punch list §B item complete. Documents the Hera-sole-owner ruling and
points to the vm_runtime.c fix (bcc72d0) and its three-arch acceptance
logs.

FABRIC.md did its job: §1-24's design argument is settled and every
implementation item through 4.5/4.4ac either landed or was explicitly
deferred with a reason. At 7,595 lines it was no longer a good place
to find what's actually still open, so it's now archival -- header
rewritten to say so, pointing to FABRIC-2.md.
Before closing it, read the entire document end to end (not sampled)
looking for anything unresolved: punch-list checkboxes, the nine
"### N.N Open" architectural subsections in §1-24, the §25.7
"reported, not scheduled" list, and any other "not yet"/"deferred"
language. Found and fixed four stale bookkeeping spots where later
work had actually resolved something but the note was never updated:
§19.6 #3 (resolved by item 2.1), §21.5 #4 (resolved by §20.5 #4), the
§25.7 stadium_owner[idx] bullet (resolved by item 4.2), and item 4.5's
own parent checkbox (all six sub-items 4.5a-4.5f were already [x]).
FABRIC-2.md carries forward everything genuinely still open: the
blocked/scoped punch-list items (1.11, 4.3, 4.4s, 4.6, 5.1-5.3, plus a
specific pending TRIPOD.md edit found within 5.3), two regressions
that were invisible with Tripod pruned to Hera-alone and are now live
since item 4.2 restored Hermes (the fleet heat leak in
vm_physics_touch(), and multi-VM heartbeat ownership), nine dead-code/
cruft reports, three open design questions (§12 Q5, §17.4, §23.4 #2),
and two documentation-debt items (the taxonomy/glossary Captain Bob
flagged 2026-08-04, and re-measuring ACL-RWT DoE overhead now that
real compiler optimization is enabled).
Also includes BLOCK_MAP.md/artemis.img/amd64.csv regenerated by builds
during this session, and a qemu boot log/DoE run that weren't from any
command in this session -- kept per repo convention, logs are audit
artifacts, not deleted.
