paper v0.3: the reinvention — accountable distribution of machine-checked evidence

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.
