proof(abi): discharge witness-discarding attestations + reconcile #130 (#33)
standards#130 claimed "5 believe_me + 5 assert_total + 5 partial" in the typed-wasm ABI surface. Comprehensive re-grep over all 21 .idr files finds ZERO trust escapes of any kind (only "NO believe_me" banner comments) — a survey-agent over-report. Verified by clean Idris2 0.8.0 build of typed-wasm.ipkg: rc=0, 0 errors, 21/21 TTC, %default total throughout. The genuine residual debt is the one PROOF-NEEDS.md §P1 names: the 15 `attestLN_*` functions required a witness in their type then discarded it (`_ = MkAttestation N Proven`), so a reviewer asking "where is the theorem?" had nothing to point at. This adds Proofs.idr §A9: an `attestLN_Sound` theorem per level that cannot be invoked without the exact witness type and proves `LevelAchievedIn N [attestLN witness]` — the missing witness ⟹ certificate-claims-level bridge for all 15 levels. Purely additive (no existing definition touched → no prior proof can regress); verified by the same rc=0 build. PROOF-NEEDS.md gets a 2026-05-18 reconciliation banner (2026-04-13 inventory retained as superseded history). Stronger "attestation entails the level's semantic property" (needs LevelAttestation reindexed by witness) remains tracked future work.

-- rubber-stamps attestations without using their witnesses" — every
607+
-- `attestLN_*` function takes a witness and discards it with `_`,
608+

-- The `attestLN_Sound` family below is that lemma, one per level.
613+
-- Each is stated so that it *cannot be invoked without a witness of
614+
-- the exact type the corresponding attestation requires*, and it
615+
-- proves the produced attestation is recognised by `LevelAchievedIn`

618+
--
619+
-- witness ⟹ the certificate provably claims level N
620+
--

-- bridge for all fifteen levels, witness-consuming at the type level.
