Authored by theologian per supervisor 12:58:10Z 2026-05-12 authorization,
addressing pythia python#353 substantive gap: A10 true-positive fire was
undefined, leaving post-c2 evaluation without a pre-specified test.

Specifies:
- FABRICATION-VERDICT counted-event definition + non-coverage clause
  (routine verification stays under feedback_no_tool_execution_citation)
- 4 outcome classes (TP / WHC / MF / TN) with mutual-exclusivity criteria
- Per-event coding schema for chronological data collection
- Pre-specified falsifier verdicts (strong-pass / weak-pass / fail) keyed
  on violation-rate vs baseline + probe-presence ratio
- Per-class diagnostic signal (high WHC -> working-memory; high MF ->
  scope gap; low TP overall -> dormant rule)
- Sample (n>=10) and horizon (5d initial / 14d defer) thresholds
- Source-of-truth corpus + initial search heuristic
- Ownership chain (theologian-author / librarian|scribe-collect /
  supervisor-dispose)
- Self-falsifying disclaimer (taxonomy / window / thresholds / heuristic
  un-falsified-at-gate)
- Explicit out-of-scope (other A-items / v3 corpus / author-exemption)

Methodology document, NOT a v2.x amendment per supervisor authorization.
v2.x moratorium remains in force.

DO NOT PUSH until c2 lands (per supervisor 12:58:10Z directive). Gate-
before-push CLAUDE.md rule applies regardless.

Authored 2026-05-12 per supervisor 12:55:33Z dispatch (pythia python#353
extended-block-contingency commitment), during the ~17.5hr c2 ASGuard
data_staging block. Read-only investigation + documented procedure for
the case where devgpu004 substrate (HEAD/c2 patch series/saved binary)
becomes unavailable before c2 push completes.

Sections:
  (a) alternative ARM64 host availability — none documented; alt-host
      spawn requires Alex coordination
  (b) bundle file size + transport mechanism — 4-patch series 65 KB,
      git bundle 67 KB, full-repo bundle 524 MB; direct scp verified
  (c) saved-binary md5 — 1444034d3af09fb18ef341b1fe6e8886 on devgpu004
      (release release; canonical content invariant = patch-id
      8fc3493dbe2655a2d15e6aa6ec4a7901cfada9b2)
  (d) build-env compatibility — cmake 4.3.2 at $HOME/.local/bin/cmake,
      NOT in default login PATH; export required before
      scripts/build_phoenix.sh

4-step fallback procedure: (Step 0) confirm decay (Step 1) re-transport
patches if missing (Step 2) reset+re-apply if working tree corrupt
(Step 3) alt-host spawn requiring Alex coordination.

Substrate-spawn-analysis acknowledged structurally circular per pythia
python#354(1) — fallback value is procedural readiness, not autonomous unblock
(supervisor 13:07:53Z disposition: acceptable scope).

Codification batch with handle-namespace + ARM64 vanilla canon per
supervisor 15:05:16Z dispatch.
