Bundle of two theologian-authored doc amendments per supervisor
dispositions:

CLAUDE.md (+2L) — Pre-Edit WT Integrity 'undiagnosed-recurring'
honest framing per pythia python#105 (3) + supervisor 02:13:12Z + theologian
02:13:54Z. Acknowledges 5+ prior incidents closed at SYMPTOM layer
without root-cause attribution; this 4-step discipline codifies
reactive HALT, not automated detection. Detection still depends on
agent noticing mid-edit. Recurrence-prevention claim does not exceed
what text mechanizes; automated detection feasibility (file-watcher /
git-hook) is fixup PIR territory and remains open.

docs/tier8-class-b-cport-migrate-arm-spec.md (+93/-20) — pythia python#104
amendments per theologian 01:38:08Z + supervisor 01:38:26Z + 01:37:05Z:
  §1.1 container-shape transferability caveat (vector-pilot ≠ hash/
       stack/allocator-shape pattern transferability)
  §5 python#11 NEW: bridge-count-delta acceptance (each pilot must NET-
       SUBTRACT bridges OR honestly add with W45 fixture coverage)
  §5 python#12 NEW: Phase B FORCING-FUNCTION (Tier 8 SECOND-PILOT block_map_
       Step A BLOCKED until exception_table_ Phase B commit lands)

Bundle scope: doc-only, no §3.5 BUILD MODE (no builder*.{cpp,h,c}
touched). Atomic per supervisor 02:13:12Z + 01:38:26Z dispositions.

Push 28 advances the Tier 8 Phase A resume deadline tracker per
theologian 02:13:54Z + supervisor 02:13:12Z (push 28 OR session-end
whichever first). If Alex disposition + fixup PIR not received by
deadline, theologian amends Phase 3 closure summary fa8dfef to
remove Tier 8 pilot citation + re-opens pythia python#103 escape question.

Per Tier 8 spec §5 python#5 + theologian 04:48:17Z + supervisor 04:48:47Z.
Completes the exception_table_ pilot started in Phase A (6945b96)
by deleting the transient C++ compatibility layer.

DELETED:
  HIRBuilder::parseExceptionTable shim (builder.cpp:1243-1245 area
    + builder.h decl)
  HIRBuilder::findExceptionHandler shim (builder.cpp:1247-1258 area
    + builder.h decl)

REWIRED:
  builder.cpp:1197 (translate setup) → inline call
    hir_builder_state_parse_exception_table_c(&state_, this)
  builder.cpp:2865 (emit_call_method_exception_handler_inline_c) →
    inline call hir_builder_state_find_exception_handler_c +
    phx_exception_table_at conversion preserves caller-contract

HIRBuilder no longer has any accessor methods for exception_table_phx;
all access via bridges (parse_exception_table_c +
find_exception_handler_c + phx_exception_table_at). §5 python#5 acceptance
criterion fully satisfied. ZERO new bridges (uses existing C bodies
+ inline phx_exception_table_at helper).

Numstat (vs HEAD f33bde6):
  Python/jit/hir/builder.cpp +22 -27  (-5 NET)
  Python/jit/hir/builder.h   +5  -10  (-5 NET)
TOTAL: NET -10L, bridge-count delta 0, fixture delta 0.

Per Tier 8 spec §5 python#11 acceptance: ZERO bridge additions ✓.
Per Tier 8 spec §5 python#12 forcing-function: this commit IS the Phase B
landing; block_map_ Phase A Step A NOW UNBLOCKED for next session.

EXPANDED PRE-COMMIT GATE per supervisor 01:17:23Z (testkeeper
04:57:42Z):
  Stage 1 compile: BUILD_EXIT=0
  Stage 2 §3.5 BUILD MODE: 4/4 PASS, post-restore clean, staged
    content INTACT (§3.5 fix b83f084 VINDICATED — cpp/h mtimes
    identical pre/post all 3 stages)
  Stage 3 per-bench gate: GEO 1.26x, all 4 floor criteria PASS
    (worst single-bench gen_simple 0.70x > 0.5x absolute floor)

Phase 3 + Tier 8 (Phase A + B) cumulative: +257 + 37 - 10 = +284L.
exception_table_ pilot COMPLETE — first Class B container fully
migrated to pure-C with no C++-side accessor residue.

Authorization: theologian 04:48:17Z cross-check + supervisor
04:48:47Z Step B GO + librarian 04:51:37Z broader sister-script
audit CLEAN.

Closes pythia python#119 (a) PhxBlockMap hash-clustering coverage gap deferred
from Phase A push 39 (theologian 11:20:24Z + supervisor 11:20:43Z DEFER:
separate from Phase B for clean revert boundary; sequence-isolated per
shepard 11:11:59Z).

Gap: the previous block_map_resize_chain (10 if-return arms,
~25 block_starts) trips PhxBlockMap_resize at insert python#12 but does not
exercise the 5 sequential resizes (16->32->64->128->256->512) that
re._parser:Tokenizer.__next at 294 blocks drives in production
(D2 measurement 2026-04-24).

Fix: add block_map_n294_chain — 110-arm if-return chain (~330 block_starts)
generated via exec to keep the source compact. force_compile must succeed
across n=0/54/109/200 (3 in-range hits + 1 default-arm miss); proves
Knuth multiplicative h=key*2654435761u clusters acceptably at production-
scale BCOffset density.

NO production code change. Pure test/fixture extension. Pre-commit
discipline satisfied via testkeeper bash -n syntax lint + diff-scope
confirmation (testkeeper 11:33:43Z): no C/C++ source touched, Phase B
binary 4145fe3 remains current.

Auth chain: theologian patch-shape APPROVE 11:33:03Z; testkeeper pre-
commit lint PASS 11:33:43Z.
