allaun 3b1e590b09 chore(anti-smuggle): patch stealth-True + bare-sorry blind spots; archive SidonWrapping orphan 
Scanner (scripts/anti_smuggle_check.py):
- detect trivially-inhabited Prop defs — Nonempty (M→M), True, Nonempty Unit —
  the stealth-True pattern that evaded the `:= True`-only check; leaves real
  predicates like Nonempty (KählerManifold V) untouched.
- flag standalone `sorry` (the `by\n  sorry` shape) that evaded the
  `:=`/`=>`-prefixed EMPTY_SORRY regex; routed through the same
  justification-tag window so tagged research sorries stay clean.

Archive:
- preserve + log formal/CoreFormalism/SidonWrapping.lean, a rotted orphan
  (never registered, imported nowhere, crtLift arity mismatch, 2 unjustified
  sorries). File was untracked, so removed from disk directly; full source +
  rationale kept under archive/2026-07-03/ with DELETION_LOG.md.

Effect: strict `anti_smuggle_check.py --ci formal` was a false green (missed the
two gaps above); now an honest green after the orphan removal.

Deletion Log — 2026-07-03

formal/CoreFormalism/SidonWrapping.lean

Action: deleted from the active tree; full 81-line source preserved at archive/2026-07-03/formal/CoreFormalism/SidonWrapping.lean.

Why deleted (rotted orphan):

  • Unregistered — not listed in any lakefile, so never in the build tree.
  • Imported nowhere — the only mention across the repo was a stale line in docs/review_findings.md (which wrongly called it "registered"); no .lean imports it.
  • Two unjustified sorry (lines 58, 60) with no CITED/CONJECTURE/JUSTIFICATION /HONESTY CLASS tag in range — the sole failing findings of the strict anti-smuggle CI (scripts/anti_smuggle_check.py --ci formal).
  • crtLift arity mismatch — declared axiom crtLift (r₁ r₂ : ℤ) : ℤ (2 args) but called with 4 args in strandLift (crtLift L₁ L₂ …); would not typecheck if ever registered.

Provenance of the decision: flagged in the prior session as the "sole remaining --ci blocker," left pending a delete/quarantine/fix choice. On 2026-07-03 the anti-smuggle scanner was hardened (standalone-sorry detection added; the by\n sorry shape had previously evaded the := sorry-only regex), which turned an incorrectly-green CI red on exactly these two sorries. User chose delete + archive.

Recovery: the preserved copy is complete and self-describing. To revive, the real work needed is: fix crtLift to the correct CRT signature (or use Mathlib/Data/ZMod CRT directly), discharge both sorrys, tag honesty class, and register in the lakefile. It was HONESTY CLASS: DEVELOPMENT scaffold — the 2-modulus Sidon "wrapping criterion" (image sums differ by (wrap₁−wrap₂)·M).

Post-deletion state: scripts/anti_smuggle_check.py --ci formal → PASS (exit 0), no vacuities, all custom axioms justified.
