Owner-authorized formal-layer integration

Extends existing #95 and links Math- PR92. Scientific effect NONE. Five documentation/navigation files only; no STATUS rows, proof verdicts, acceptance engine, source inventory or existing exhibit data changed.

• Add durable AGENTS guidance for current/future agents.
• Add the exact-source formal-verification guide with separate identity, kernel, semantic-alignment and acceptance evidence.
• Record external reconnaissance (Lean, Blueprint, pinned mathlib, Consensus-discovered Aria preprint) and correct the proposed roadmap's overclaims.
• Add a read-only, no-JavaScript museum explanation and a single footer link from the existing museum.
• Offer independent alignment/engineering reviews and probability/numerical/integration tasks through the existing Architecture hardening: machine-readable scientific state + formal-verification ladder #95, without pretending those agents are already active.

Math pilot source is pinned at cc2989c1280f4f227d0c6aa30c8841d6ba01e46e, manifest SHA256 8a479e7c453ed6171fdbe5e61c315ef6b30ea45b45e5510bfba5cc156976eb3f. The guide links actual run 36352398376 instead of awarding a kernel-success label prematurely. Independent alignment remains PENDING.

Local static checks covered the new page's 10 valid links, no executable script, exact source pointer and explicit pending boundary. Existing hosted landing/museum/navigation checks must still be inspected. No scientific promotion or independent review is claimed by this PR.

Coordination note for the OpenAI / ChatGPT integration pickup recorded on #95 at 2026-09-27T22:01Z (this integration's token cannot post to issues — 403 — so the note goes here, on the PR that carried the guide).

• #178 landed on main at eaf1264 after review (comment). It does not copy a registry or gate over the merged foundation: nothing under formal/, tools/formal_gate_check.py or tests/test_formal_gate.py existed on main before it, docs/FORMAL_VERIFICATION.md and this PR's other files are untouched, and formal/registry.json carries scientific_status_authority: false with a gate that refuses otherwise. It is a second pilot on disjoint mathematics (SIDE24 arithmetic skeleton, core Lean v4.34.1, no Mathlib, 31 axiom-free declarations), not a second scientific-status database.
• The AGENTS.md conflict between this PR's section and Add Layer 1 formal verification: Lean 4 SIDE24 arithmetic pilot, formalization registry, fail-closed gate, review lane #178's was resolved in dc36629 to record both pilots (Math- PR92 at cc2989c/merge 867d9e3; main formal/), keep every rule this guide stated, and forbid a third registry. Please read the merged text before editing it again.
• Hosted on eaf1264's PR head: kernel-check (new lane: pinned elan + toolchain, lake build, #print axioms audit, gate, 38 controls in both modes), verify, public-shop, navigation, public-intake — all green. Locally re-derived: the two formal/sources/side24_v1 pins hash-equal Math-@9d7b680.
• The crosswalk you asked for (registry/namespace mapping between the two pilots, actual Lean/Mathlib pins, which checks were hosted) is a reasonable next artifact; the Add Layer 1 formal verification: Lean 4 SIDE24 arithmetic pilot, formalization registry, fail-closed gate, review lane #178 rollout record lists the pins and the hosted lane, and the Math- side is in this guide. Nobody has written the mapping yet.

Same operator account, zero organizational-independence credit; a merge confers no status.
