A12-T2 gen-2 ceremony: Stage-2 lawful stop (exact-token join witnesses)

[MaxGhenis]

Summary

Second-generation tier-2 certification attempt under operative revision 20 (Amendment 18). Stopped lawfully at Stage 2; report sol-ce-a12-tier2-r04-r06-gen2-report.md (three topology-preserving stage commits, report-only — zero governed-surface changes vs base ae68be8).

Banked (Stages 0–1, first time ever executed):

• Revision-20 operativity authenticated via the unmodified public oracle: (13,14,15,16,17,18), A15 selected at position 2 — the §32.3 cure works in production; the gen-1 revision-binding gap is conclusively resolved with "one mandatory execution and no residual composition choice."
• The complete §32.2 full-source build: 279-row domain (257 source + 22 repair/seal), 2,741,145,128 bytes authenticated byte-for-byte, all six §29.4.3 comparands freshly reproduced, and the first-ever derived tier2_build_input_domain_sha256 = f34ced6e…cd52fff63 — byte-identical to the A18 round-2 referee's independent reconstruction (168,504-byte envelope, two fully independent lanes). §32.2's preimage law is deterministic in practice.

The stop (Stage 2): two independent reconstruction lanes each found a different retained, source-classified 1971 field_purpose_prompt with no admitted exact source-token reference under either §19.3.3 join branch:

1. Document-007 p.49 interviewer-guidance prose ("Family income is, of coun:e…") — first token Family fails the letter-plus-digit predicate; zero candidates across the complete 555-member D_1971.
2. Document-007 p.19 token Dl7. (OCR lowercase-l for D17./V1999) — exact-token law admits no normalization; zero candidates across all 1,665 canonical field rows.

No repair overlay supersedes either row; §§19.3.3/19.4.1/26.11.2/29.4.1 make R04 conjunctive and fail-closed, so the builder was never instantiated. These are the executed byte-exact witnesses of the defect class that Amendment 19 (#398, source-hierarchy member-construction cure) adjudicates systemically (~246/21,971 prompt coverage per its referees; forecast entry 19 repriced accordingly).

Resumption per the report: after A19's revision-21 activation (repin lane already in gate), restart at Stage 0 in a fresh worktree (sol/a12-tier2-r04-r3).

Ceremony: sol via codex-run; fable review verified commit containment (report-only), the §19.3.3 branch citations, and the cross-lane digest identity.
