Claude c76a742f2b #188 : the Jacquard selector's 64 cards, L7 permanently on, L2 a real gate

Captain Bob, 2026-11-12: "Wire L2, keep L7 on". The table held the 128
cards of the 7-bit L1-L7 space; nothing read L7, and the rolling window
recorded whatever the card said, so the 128 were 32 behaviours.

- compudynamics.c: cd_tuning_word() sizes the table to 64 (L1-L6).
- ssm_jacquard.c: card_bits() makes a card's 7-bit mask, L7 set, where a
  card is read, seeded and started (C4: 17 -> card 8);
  ssm_l8_force_config() still takes the 7-bit index, its L7 bit implied.
- physics_execution_hooks.c, kernel vm_core.c: the rolling window records
  only while L2 is on (or before there is a config).
- ssm_jacquard.h says what is wired, bit by bit (it said L7 was);
  v3/CLAUDE.md and the L8 reference corrected in place; FABRIC-3 XLVIII.21.

Tests first, seen to fail against HEAD (logs/20261112-210510/kernel-tests):
test_ssm_jacquard 4 of 7, test_physics_l2 1 of 4; all pass now. v4 reads
no rolling window: acceptance is unchanged; the protocol runs next.

Raw Blame History

v3/CLAUDE.md -- loaded when working under v3/ (moved from .claude/CLAUDE.md, 2026-11-06)

Physics-Driven Adaptive Runtime

Uses thermodynamic metaphors as modeling language (see ONTOLOGY.md):

Loop #1 — Execution Heat (dictionary_heat_optimization.c) — frequency counter per word
Loop #2 — Rolling Window (rolling_window_of_truth.c) — circular buffer, execution history
Loop #3 — Linear Decay — quiescent words lose heat over time
Loop #4 — Pipelining (physics_pipelining_metrics.c) — word-to-word transition prediction
Loop #5 — Window Width Inference (inference_engine.c) — Levene's test, binary chop
Loop #6 — Decay Slope Inference (inference_engine.c) — exponential regression
Loop #7 — Adaptive Heartrate (HeartbeatState) — background tick coordinator

L8 Jacquard Mode Selector (ssm_jacquard.c) — a 64-card loop-gate selector: L1–L6, with L7 permanently on (corrected 2026-11-12, #188 -- this said "a 128-state, 7-bit" selector; the cards differing only in L7 or the then-unwired L2 acted alike). In this repo it now has a real per-VM heat channel into fleet-wide tuning (VM Fleet Attractor physics — see docs/working/architecture/VM-FLEET-ATTRACTOR-DESIGN-20260705.md), replacing hardcoded compudynamics constants with a dynamically-inferred rate.

Critical Implementation Details

DoE CSV Output Suppression

Intentionally suppressed as of 2025-12-08. See v3/src/main.c:390-396:

Metrics still collected via metrics_from_vm()
CSV row was redundant with internal VM metrics
To re-enable: add a --csv-export flag or write to a file

Heartbeat Instrumentation (Planned)

HeartbeatTickSnapshot and tick_buffer are declared in v3/include/vm.h, but heartbeat_export_csv() is not yet implemented.

Word Statistics Output

WORD-ENTROPY prints execution heat statistics to stdout. Kept enabled in DoE mode intentionally (diagnostic value outweighs noise cost).

StarKernel M7 Parity

parity.c logs every VM birth and execution with: VM ID, capsule hash, dictionary hash. This enables offline determinism verification — an independent system can load the same capsule and compare dict hashes. Zero-deviation means 0% algorithmic variance.
