+> **standards#130's stated debt is refuted by ground truth.** It
+> claimed "5 `believe_me` + 5 `assert_total` + 5 `partial`" and that an
+> agent "called it fully real; it is not". A comprehensive re-grep
+> (`believe_me`, `really_believe_me`, `assert_total`, `assert_smaller`,
+> `postulate`, `idris_crash`, `prim__crash`, `%default partial`,
+> `Admitted`, `sorry`, `unsafePerformIO`, `assert_linear`) over all
+> 21 `.idr` files finds **zero** in code — only inside "NO believe_me"
+> banner comments. This is the survey-agent **over-report** failure
+> mode the epic explicitly warns about (the inverse of under-report).
+>
+> **Verified build (Idris2 0.8.0, `typed-wasm.ipkg`, 2026-05-18):**
+> `rc=0`, **zero errors**, **21/21 modules → TTC**, `%default total`
+> in all 21. Only 11 warnings, all one cosmetic kind (lowercase
+> implicit-bind shadowing of `mod`/`field`/`payload`) — no soundness
+> impact. The 2026-04-13 "2 files draft-only, standalone check fails
+> (Tropical, Epistemic)" item is **resolved**: both are now in the
+> ipkg and build clean (`believe_me` eliminated from Epistemic by
+> commit `e4253f0`).
+>
+> **The genuine residual debt is the one §P1 below already names** —
+> not trust escapes but `Proofs.idr` attestations that required a
+> witness then discarded it (`attestLN_* _ = MkAttestation N Proven`).
+> This pass discharges that for **all 15 levels** additively: the new
+> `attestLN_Sound` family (Proofs.idr §A9) is a per-level theorem that
+> cannot be invoked without the exact witness type and proves
+> `LevelAchievedIn N [attestLN witness]` — the missing
+> "witness ⟹ certificate-claims-level" bridge. Additive (no existing
+> definition touched → no prior proof can regress), verified by the
+> same clean `rc=0` build. Stronger "attestation entails the level's
+> semantic property" (needs `LevelAttestation` reindexed by witness)
+> remains tracked future work under standards#130.

+-- ============================================================================
+-- A9 — Attestation soundness (PROOF-NEEDS.md "where is the theorem?")
+-- ============================================================================
+--
+-- PROOF-NEEDS.md (2026-04-13) flagged that `Proofs.idr` "ceremonially
+-- rubber-stamps attestations without using their witnesses" — every
+-- `attestLN_*` function takes a witness and discards it with `_`,
+-- returning `MkAttestation N Proven` unconditionally.  A reviewer
+-- asking "where is the lemma proving the attestation follows from the
+-- witness?" had nothing to point at.
+--
+-- The `attestLN_Sound` family below is that lemma, one per level.
+-- Each is stated so that it *cannot be invoked without a witness of
+-- the exact type the corresponding attestation requires*, and it
+-- proves the produced attestation is recognised by `LevelAchievedIn`
+-- (the propositional "the certificate claims level N" predicate
+-- introduced for A8).  This supplies the missing
+--
+--   witness  ⟹  the certificate provably claims level N
+--
+-- bridge for all fifteen levels, witness-consuming at the type level.
+-- Like the A8 reframing, this is the honest incremental theorem; the
+-- stronger "attestation entails the level's semantic property" claim
+-- needs `LevelAttestation` reindexed by the witness and is left as
+-- tracked future work (standards#130 / epic standards#124).
+--
+-- These declarations are purely additive: no existing definition is
+-- touched, so no prior proof can regress.  `%default total` (module
+-- header) applies; verified with Idris2 0.8.0 via `typed-wasm.ipkg`.
