Executes the approved reinvention outline, using the round-11 GPT-5.6
draft as base material; the operator remains the author of record and
this pass is the authorial fact-check + completion of that draft. New
title: 'Accountable Distribution of Machine-Checked Correctness
Evidence: A Transparency Model and the Lean Transparency Log' (16 pp).
Old 19-page system report archived byte-identical as v0.2
(paper/ltl-v0.2.{tex,pdf}, served at /paper/v0.2; v0.1 unchanged).
Every factual claim in the draft was verified against the estate before
adoption: 222 inventoried constants + 61 reviewed cones (README:36),
all four fidelity counts, the gap-14 lied-size witness reproduced
empirically (deployed verify_consistency(1,3,R2,R3,P)=True while the
recursive model rejects; honest 2->3 True/True), all four apex theorem
names greped from the dalek repo, the entry-13 scope block now quoted
VERBATIM (was silently trimmed), the new klaus2026 citation confirmed
real via the arXiv API (author order corrected to Klaus, Conejero,
Tolmach), remaining 20 bibitems byte-identical to the F10-verified set.
Author corrections beyond the draft: 'opaque SHA-256 function' ->
uninterpreted/boundary AXIOM (matches axiom sha256 : List UInt8 -> Hash);
STH field list now matches the deployed head (adds type tag); lied-size
mechanism sentence from the gap ledger; six-published-heads (sizes 8-13)
mirror honesty; consumers subsection (warden + Swiss Post family-level
negative) per outline item 7; optimistic-accountability related-work
paragraph per outline item 8; fifteen-gap ledger pointer per outline
item 9; verify.py fail-closed tie-ins in artifact availability and
appendix C; wired the six uncited bibitems (lean4, pnueli, eddsa,
rfc8032, edwards+twisted, easycrypt); certificate listing gains the
deployed 'diagnostics' field. Build: 16 pages, 0 overfull, 0 undefined.
web.py: /paper/v0.2 route + loader. webdocs: paper card rewritten for
v0.3 with both archived versions linked. Suite 115 green.

- §5/N1: the '16/16 proven' pill was hardcoded — false for the
accumulator (61 certs). Now computed proven/total from each
component's newest leaf (forks show 16/16, accumulator 61/61).
- §2: 'the only thing you take on trust' → 'sole cryptographic identity
anchor; truth rests on each leaf's stated assumptions' (both the top
card and the download table).
- §3: 'the signature vouches for the code that produced it' → the signed
tree CONTAINS an attestation of the reported signing source; execution
provenance is reported, not proven; provenance fields are unsigned
metadata.
- §9: 'irrevocably part of the log every other customer sees' → this
signed head commits it to THIS view; comparison exposes split views.
- §4.4: witness 'never equivocated' → a retained view that can EXPOSE a
conflicting head; one clone cannot prove no split view.
- §10: 'the git hash is the content hash' → the commit identifies the
committed git tree, not deps/toolchain/artifacts.
- §6: live-site 'twelve-leaf deployment' blurb → 'live deployment'.
Suite 115 green.

Responds to the converged positioning diagnosis (GPT-5.6 post-mortem +
round-6 reviewer): inverted structure — trust-decomposition model
first, design-space comparison section, LTL as instantiation, gap
14/15 presented as a located-and-fenced result, entry 13 as Exhibit A
(the only-this-paper claim; rewrite finalizes AFTER the append so the
abstract cites the live leaf). Lists what moves out, venue sequencing
(arXiv then CPP/ITP/SCORED/RWC), and the success criterion (the
thought-experiment polarity flip). Old ltl.tex remains hosted as the
system report; queued wording fixes are absorbed by the rewrite.

Its last two callers vanished in the round-6 hardening (parse anchors
on the exact phrase via regex; classification is membership-based).
Dead code in an audited producer invites misreading. Suite 115.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Found by the entry-13 12->13 rehearsal: build_attestation emitted
subject/environment/replay/certificates but NO scope — the profile's
guarantees/exclusions/deployment_constraints (which carry a repo's
known_status scoped-claim wording and known_exclusions) reached only
the claim card, never the published leaf. So the round-6 requirement
that entry 13's LEAF carry its scoped attestation text was unmet by the
code; a reviewer who checked the claim card saw the wording that the
leaf did not contain. Added a 'scope' block
(guarantees/exclusions/deployment_constraints) to the leaf; pure text,
safe to publish, validator is additive. Two provider tests assert the
block exists and that a repo's known_status/known_exclusions reach it.
Suite 115 passed.

R6-B1 (Claude, executed end-to-end): provenness was decided by a
WHOLE-OUTPUT 'no axioms' sentence, so an axiom-free certificate whose
line was entirely absent still scored proven+clean ([]==[]). The
reviewer drove a doctored 60-line output through the real gate and got
61/61 with domsep never audited. Classification is now extracted into
classify_certificates(): proven iff the certificate's OWN anchor was
parsed (axiom-free anchors populate []); absent certs are
unknown/failed + not_checked — never clean. This also fail-closes the
typo'd-future-cert case (R6-C2).
GPT §6: parse_axiom_output is now RECORD-scoped — anchors delimit
records, a cone bracket is accepted only inside its own record, missing
or truncated brackets yield MISSING (fail closed) instead of borrowing
the next certificate's bracket, and cones may wrap arbitrarily (the
old fixed 16-line window was a latent overflow for the 11-axiom
ed25519 apex cones on this estate). Anchor names are captured between
the exact quotes Lean prints.
Six new regression tests (absent-axiom-free-not-clean, missing-bracket
no-steal, truncated cone, >16-line wrap, duplicate anchor, interleaved
diagnostics). Suite: 114 passed / 0 failed.

Rehearsed end-to-end 2026-07-16 (throwaway key + throwaway log):
compile via the corpus's lean-guard, 61/61 certificates proven with
byte-exact cones (post parser fix 34a0457), append, publish,
witness-audit ok. kind merkle_accumulator uses the generic profile —
everything comes from this entry: the 61 fully-qualified certificates
with per-certificate cones (generated from the corpus's CONES table),
the nine Proofs.* axiom_imports (required — without them the generated
audit file has no imports and lean-guard rejects it), and known_status
carrying the REQUIRED scoped attestation wording (runbook B2 gate /
round-4 GPT §11): the mechanized model is verified; deployed
consistency correspondence relies on the unmechanized authentic-pair
invariant (KNOWN-GAPS 14/15).

Found by the entry-13 rehearsal (the accumulator corpus is the first
subject with axiom-free certificates — every fork certificate carries
at least the boundary axiom, so this path was never exercised):
- an axiom-free certificate ('X' does not depend on any axioms) was
parsed by opening a 16-line window and taking the first bracket in
it — which belongs to the NEXT certificate. domsep/Hash/
instDecidableEqHash/take_append_drop were reported with their
neighbors' cones and flagged dirty.
- certificate names were matched as bare substrings, so 'Foo' could
anchor on the line for 'Foo_bar'. Now anchored on the exact quoted
name Lean prints.
The no-axioms decision is now made on the anchor line itself, before
any window. Two regression tests added (steal-next-cone, exact-name);
suite 108 passed / 0 failed.

All six originated from the author's own adversarial read-through:
1. SS9: retrievability decay — leaves whose pinned commits are no longer
distributed (0-7 post-rewrite) decay to historical record.
2. SS4.3: why-a-tree — per-item signatures cannot evidence deletion,
expose forks, or provide pinnable state; dishonesty-evidence, not
scale, is the motivation.
3. SS1: curve/signature crate parenthetical (one implementation).
4. SS8: ~1,800s/fork corroborated by inter-leaf issued_at spacing
(within-run gaps 29m35s-30m40s).
5. SS5.1: git commit ids are hardened SHA-1 — said before a referee
says it.
6. App A box fidelity: logical-vs-canonical order declared; ellipsis
markers inside cert objects and at attestation level (covers
diagnostics + inner schema_version); '(14 more)' -> '(14
certificates elided)'.
Visual inspection: all changed pages (1,5,6,13,15,16,17) plus spill
pages 18-19 read with own eyes; p.19 is a light final page (App D

Review A (second Fable instance, delivered via USB, findings re-verified
by me against the tex before adoption; its frontier lemma re-derived from
scratch before applying):
- THE REAL FIX: Lemma 2's hash-fold definition did not cover its own two
uses (Root recomputes only along the leaf's root path; ConsRec bottoms
out at the [0,n0) decomposition and consumes the pinned root, which the
old Steps 1-2 never pinned - incl. the degenerate case where the first
component IS the pinned root alone). Now: folds shaped by a connected
sub-tree S containing the root, children outside S consumed as opaque
inputs, conclusion pins emitted values AND all consumed inputs; Thm 2
names its S; Thm 3 pins the consumed anchor and handles the degenerate
case; Lemma 1's role stated honestly.
- dangling R4/R5 taxonomy labels removed; G3/Prop 2 statements now match
their own veto-proof (deny-only, everywhere); Table 1 caption counts
boundary+standard-three; r1 defined as raw signature bytes (T1's whole
point); Contribution 4 'embedded in every signature' -> 'published
alongside'; Figure 1 redrawn in the exact RFC 9162 shape for n=12;
Solana error-type nit; App D namespace elision noted.
Review B (GPT-5.6, positions defended 2026-07-10, concessions adopted):
- abstract + G2 narrowed to what Prop 1 proves (same-size evidence +
monotonicity), unequal-size split views routed through the public leaf
mirror; residual-trust sentence stated at honest width (checkout, deps,
binding, parsing in the trusted observation pipeline); freshness
declared an availability policy (freeze attacks not prevented);
self-reference verb 'ensures' -> 'enforces and records' + signature
reveals nothing about the producing program; novelty softened to
'we are unaware of'; 25-line/150-line accounting in one breath;
missing-oracle-axiom = refuse-to-classify drift (keeping the oracle
argument); mechanization tone softened; head-encoding reality
documented (versioned canonical JSON w/ log id - system was ahead of
the paper); NEW claim-matrix table (Table 2) decomposing every consumer
conclusion into mechanism + residual assumption, incl. two deliberate
not-established rows.
Open questions from Review A resolved: black_box 27 lines are per-lemma
trusted-base bookkeeping (no published cone contains black_box -
verified); T4 x=0 edge case now stated precisely (roots coincide, set
sign bit rejected per RFC 8032, covered by the iff over extracted code;
Lean sqrt_core handles x=0 explicitly); Cheval pages (DBLP-verified)
restored alongside Review A's DOI.

Two Fable-5 inventory agents cross-checked every empirical claim in the
paper against code/deployed log, and every external pointer against the
live internet. Fixes on both sides:
CODE (system brought up to the paper's claims):
- SECURITY: pin-store mutation (incl. permanent poisoning) was reachable
via receipts whose head signature FAILED verification in two of three
consumer paths (attestation.py, cli.py) - an unauthenticated forged
head at the pinned size could poison a consumer's pin forever and
pollute the equivocation-evidence pair with an unverifiable head,
contradicting SS5.4's 'validly signed' precondition and Prop 1.
Both paths now gate the store on a verified Ed25519 head signature
(logclient.py already did). Regression test added.
- Prop 2 made literally true: _normalize_certificate now derives the
cleanliness verdict purely from (observed cone, local allowed set) in
EVERY branch; the operator's axiom_status label is never copied (was
passed through for non-proven certs), missing cone => unverifiable
always. Labels can deny, never grant. Test added.
- webdocs: '/v1/sth-history: every head ever signed' -> 'the published
head history'.
PAPER (claims brought down to reality):
- 'every head ever signed' -> the signed head history since publication
began (heads for sizes 1-7 predate the mirror and were not retained).
- Run-3 bullet: 'independently checkable by diffing the two commit
trees' was no longer reproducible (pre-rewrite objects discarded);
now states the log-internal corroboration (identical cert lists and
cones across leaves 4-7 vs 8-11) and that tree diffs are not public.
- Appendix A leaf block now actually verbatim: scheme
openssl-ed25519, verified_backend serial/u64, real Lean version
(4.30.0-rc2) instead of 4.x.y placeholder, leaf's actual axiom order
(finalize/new/update), machine_protection note quoted, elisions
marked; preamble wording matches.
- Appendix C upstream boundary reordered to check.sh's verbatim order.
- '27 lines - all annotation' -> honest description (axiom-list entries
+ operation reordering from one fork's black_box barrier).
- Prop 2 proof + App A: status label consulted only negatively.
- SS7: provenance fields noted as outside the signed payload; consumer
chain relies on none of them.
- Bibliography: all 20 entries verified against DBLP/RFC-editor - zero
errors; added missing page numbers to 6 entries; thebibliography
width 19->20. All URLs verified public; no PlanetMacro leakage.

Adversarial re-read of the security section found three exposition gaps
(no math errors, but the kind a referee pounces on), all fixed:
- Lemma 2 (Root binding): Theorem 3 Step 1 asserted 'every proof node
consumed is genuine', but the lemma's STATED conclusion only mentioned
values F emits, not siblings F consumes. Strengthened case (ii) to pin
the consumed siblings explicitly (it follows from argument-pair
coincidence, now stated, not just proved).
- Theorem 3 Step 3: 'hash-fold over itself' named the wrong object — for
Lemma 2, T_{D1[0:n0]} must be a hash-fold over T_{D0}; justified by
equal size => identical shape, leaf inputs = D1[0:n0].
- §7: 'self-referential without being circular' was asserted; now argued
via the explicit acyclic verification order (pin key -> check sig ->
verify inclusion by hashes -> optionally rebuild+recheck source), no
step consuming its own output.

Re-auditing the prior (Opus-produced) depth pass adversarially found and
fixed three genuine issues:
1. OVERCLAIM (serious): §5.3 said the consistency verifier was
differential-tested 'on all (n0,n1) with n1<=256' but the script only
SAMPLED sizes (5,508 cases). Ran the genuinely exhaustive test — all
1<=n0<=n1<=256, honest + 4 mutations — 164,224 invocations, and the
inclusion verifier likewise (164,479). Paper now states the true scope
and counts; both are pinned in a new CI test (test_paper_verifiers.py,
104 tests) so the numbers cannot rot.
2. PROOF IMPRECISION: Lemma 2 (Root binding) was applied to ConsRec's
first component, which PASSES THROUGH (no hnode) at some levels and so
is not the hash-fold the lemma needs. Reworked: Lemma 2 now defined
over 'hash-folds' only; Theorem 3 restructured into 3 clean steps that
put only the full-hashing second component through the lemma, then
argue algebraically + one honest-tree collision. Also hoisted Lemma 2
above Theorem 2 and made Theorem 2 invoke it (was inlined), so the
'two theorems share the lemma' remark is now true; deduped the remark.
3. MISLABELED TABLE: Table 1's 'files vs upstream' column actually held
line-diffs against different baselines. Dropped it for clean comparable
columns (files / apex axioms / SHA-512 shape); the diff story stays in
the portability paragraph where each baseline is named.

Not size for its own sake; each addition is a definition, proof, figure,
or measurement the genre expects and the rejection implied:
- §2: the signature apex given real depth — the four tiers stated as an
explicit lifting ladder T1-T4 (byte apex -> canonical half-lift ->
injectivity/point-eq via non-square d -> constructive full lift), each
naming the one new mathematical fact; the corpus's actual achievement,
previously an appendix bullet list
- §4: scheme-syntax Definition (KeyGen/Append/ProveIncl/VerifyIncl/
ProveCons/VerifyCons/Verdict) in DGHS style, so the goals name real
algorithms; new subsection making the observation-not-verdict /
requirements-card idea explicit (the system's distinguishing claim)
- §5.3: the consistency verifier DEFINED (recursive ConsRec form),
closing the gap where Theorem 3 previously reasoned about an
undefined verifier — differential-tested == deployed RFC verifier on
5508 cases (honest + 4 mutation classes, n<=256)
- §6: Theorem 3 now a FULL proof (was a sketch), factored through a
shared Lemma 2 (Root binding) that both soundness theorems use
- §8: Figure 1 (the twelve-leaf tree w/ grey failure leaves + 3-run
braces) reinstated and improved; Table 1 (per-fork files/boundary/
diff/hash-shape) replacing a prose paragraph
- App D slimmed to the verbatim Lean theorem-name mapping (no longer
duplicates §2)

Makes the paper's pin-store safety proposition true in the deployed code:
- the full signed STH is retained at pin and at each advance (not just
size+root), so on equivocation both conflicting heads are transferable,
signature-verifiable evidence;
- any equivocation (same-size root mismatch, or a consistency anchor
disagreeing with the pin) persists poisoned=true with both signed
heads and refuses ALL further operations for that log, restart-proof
and independent of the update flag;
- rollback unchanged. 102 tests (was 100): poison persistence, evidence
transferability, full-head retention.

Consolidates the consumer-side trust framing that was scattered across
notebooks 05/06b and WALLET.md into one on-ramp: the allowed-axioms list
as a requirements card you own and can write yourself; measurement vs
publication vs judgment (operator/log/you); the three honest outcomes
when your card is stricter than the supply (relax itemized / walk away /
grow the supply). Executable: a self-written card is shown to equal the
real APEX_BOUNDARIES cone exactly (supply == wish: True), and a strict
no-oracle card is REFUSED with the real SHA-512/wire gap itemized.

Socratic audit findings, all verified against artifacts:
- 'zero lines between structurally identical forks' was FALSE: risc0 vs
betrusted differ by 27 lines (all annotation, documenting the risc0
fork's black_box trusted-base entry). Corrected to the true number.

- completeness parenthetical now states both hypotheses (a=-1 square, d
non-square), not just d.

Correctness:
- ledger: single-flight fcntl lock over read-modify-append + fsync. Two
concurrent writers previously could fork the hash chain (read same tail,
same prev_hash). New test races 8 threads x6 appends; chain stays intact
with contiguous indices.
- small-order list: the order-8 encodings were hand-typed and unverifiable
and diverged from the canonical libsodium blocklist. A BOGUS entry is the
only dangerous direction (it down-grades a real tamper to a note, skipping
the latch), so the list is now the certain-low-order set only (y in
{0,1,-1}, reduced/non-reduced, both sign bits); order-8 edges escalate to
tamper until a derived list lands. Fail-safe asymmetry documented + tested.
- freshness: removed a tautological .
Non-functional:
- quorum members now run concurrently (ThreadPoolExecutor): a verify costs
one member's latency, not the sum (~17ms for 4 members, live).
- Wallet.quorum() memoized per state_dir: binary swap-detection hashes run
once at assembly, not on every verify; documented rationale.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- walletmcp.py: stdlib stdio JSON-RPC MCP server; 7 outcome-first tools
with strict schemas; errors are structured (code/missing/remediation),
never prose; results carry evidence (structuredContent)
- custodycard.py: A2A-style card sharpened to self-proving - embeds each
member's LTL inclusion proof + STH so a counterparty recomputes trust
instead of believing it; proof-of-posture nonce challenge returns a
firewalled, signed posture attestation with the full quorum trail
- cli.py:
- verified end-to-end on the live wallet: all 7 MCP tools, structured
refusal on bad input, and a counterparty recomputing all 4 inclusion
proofs + STH signatures from the card alone (no operator trust)

- Wallet.init is the R4 gate in executable form: per member, the built
binary's source commit must match an attestation whose verdicts are
re-derived locally, scored >= R4, and Merkle-bound to a verified STH
under the log key (explicit --trusted-provider required, never inferred)
- append-only hash-chained ledger; latch semantics (tamper => custody
frozen; unlatch is a deliberate operator act recorded with a note)
- outbound: intent envelope bound to payload bytes -> signer (local
dogfood or airgap/Precursor-style outbox) -> quorum firewall; a
rejected self-signature is quarantined, never released, and latches
- refusal receipts: signed machine-actionable artifacts (code, missing,
remediation); unsigned-by-design while latched
- live end-to-end against ltl.zkdefi.org: 4 members R4 (leaves 4-7),
release firewall unanimous-accept, inbound unanimous-accept, refusal
signed, ledger chain verified

- dogfood/quorum/verify-{dalek,anza,risc0,betrusted}: verify-only crates
built from the pinned proven source workspaces (serial backends pinned
per fork; anza entry is the certificate-covered verify_sha512, not the
default Zebra-lineage verify())
- src/pacta/quorum.py: unanimity-required acceptance, divergence
taxonomy (semantic-edge vs unexplained/tamper), small-order/canonicity
edge flags, per-member provenance sidecars with binary hashes
- live smoke: 4/4 members agree on accept and reject

- web.py: /paper (and /paper/ltl.pdf) serve the committed PDF, loaded
once at startup from the repo checkout; listed in the 404 endpoint
index; covered by the web roundtrip test
- docs page: 'The paper' card linking the PDF
- DEPLOY.md: the second witness mirror belongs on a host the operator
does NOT control (a self-hosted mirror adds no equivocation defense)

- serve/webdocs/cli default to base_path='' (own subdomain, root serving)
- webdocs link builder handles the empty base like web.py already did
- all docs, paper, notebook 06b, and published-mirror README point at
https://ltl.zkdefi.org; DEPLOY.md rewritten for subdomain + redirect
- tests: root mount is the production shape; one test keeps exercising
the path-mounted variant

Review feedback applied:
- Author: Olaf Horvath.
- New "What the certificates state" block in the introduction - the
actual mathematics the Lean proving is about, kept compact: the
radix-51 denotation, a representative two-clause specification
(value + invariant preservation for mul), the complete twisted
Edwards addition law with the d-non-square completeness fact, and
both apex tiers as single-line equivalences
(accept <=> compress([s]B-[k]A) = R; accept <=> decompress(R) =
[k](-A)+[s]B) with the hash oracle's role stated inline.
- The figure was genuinely broken (leaf boxes overlapped - box width
exceeded spacing - and the annotation collided with a node); this
time it was inspected VISUALLY, not just for build warnings.
Redrawn as a full-width figure*: generous spacing, grey failed-run
leaves labeled "retained forever", bold leaf 4, the dashed
self-certification loop routed through clear space, and the float
relocated in source so it lands on page 3 beside the deployment
section instead of drifting to the references page.
- Held the 4-page line through prose trims (intro paragraphs, related
work, deployment opening) and a compact accept() notation; zero
build errors, one 0.66pt overfull in a bibliography line.

paper/ltl.tex + built PDF: "LTL: the Lean Transparency Log -
Distributing Machine-Checked Proof Evidence via an Authenticated Data
Structure Signed by Its Own Certified Artifact". Exactly four pages,
two-column, self-contained (embedded bibliography, TikZ figure of the
real 8-leaf log with the self-certifying signature loop).
Structure: intro (the consumption-economics argument), the LTL
(roles, replay-attestation leaves, boundary-exact auditing,
observation-not-verdict, pinning + git witness), the self-certifying
signature (with the honest verify-path/signing-path distinction),
deployment & evidence (the failure leaves as a feature; the full
assumption enumeration; the proof-portability observation with real
divergence numbers), related work (Rekor/CT/PCC/CONIKS/in-toto
engaged head-on; Cheval-Moreira-Ryan as the complementary direction -
"they verify the log; we log the verification"), limitations, and the
next-step agenda (Lean-verified RFC 9162 verifiers with SHA-256
collision resistance as a documented boundary axiom, certificates
entering the log they defend; EverCrypt/verified-Merkle prior art
credited).
Claim discipline verified on the rendered text: zero hype vocabulary,
explicit does-not-establish list, full trusted-base enumeration,
single-operator/TOFU/prototype-scale limitations stated, AI drafting
assistance acknowledged. References verified against the literature
(Sigstore CCS'22, Aeneas ICFP'22, HACL* CCS'17, Fiat-Crypto S&P'19,
EverCrypt S&P'20, in-toto USENIX'19, CONIKS USENIX'15, RFC
6962/9162/8032, Necula POPL'97, Lean 4 CADE-28, Bernstein et al.).
Footnote acknowledges the linear-temporal-logic acronym collision.

The pacta repository is now public on GitHub. The server's app/ was
re-cloned from it (previously shipped via tar+scp while private), so the
production update path is now pure git pull for both app and published
log - no code shipping. Verified live after the switch: internal healthz
and the public docs site both 200, tree size 8. DEPLOY.md runbook
simplified accordingly.

Deployed from the provider notebook over the dedicated deploy key. The
host runs a compose stack, so the LTL joined it as a read-only container
(read_only: true, :ro volumes, no published ports, compose-network-only)
rather than the host-systemd variant; the domain's Caddy site block
gained a path handle that precedes the existing catch-all, validated in
a throwaway container before reload, with timestamped backups of both
config files. The servable log dir is reconstructed FROM the published
GitHub mirror (the server holds witness-grade data only - no keys).
Live smoke over the public internet from the provider machine: /docs
(the SVG site), /v1/sth, /healthz (tree size 8) all 200; the existing
service on the domain unaffected; and the complete agent flow ran
against the production URL - log-fetch, receipt-verify through the
dogfood verifier with a fresh pin store and freshness policy, and
sth-refresh confirming pin consistency online.
DEPLOY.md now leads with the as-built compose record + update runbook
(reconstruct.py helper installed server-side); the original systemd
variant is kept for docker-less deployments. 54/54 tests.
