will.anderson 0af39df16f M-INTEROCEPTION P2: chronoception — age the activation field by measured wall-clock delta (ENGRAM_CHRONOCEPTION, default OFF)
The felt passage of time is the cooling of the activation field, not a tick
count and not an elapsed-seconds readout. engram_age_field(delta_ms) cools the
field (working_memory_weight + background_activation) by the caller's MEASURED
wall-clock delta with a pure exponential exp(-dt/TC) — no per-call floor — so it
is exactly scale-invariant: N ticks summing to the same elapsed time produce the
same total cooling. It returns the cooling MAGNITUDE (1-exp(-dt/TC), a bounded
[0,1) drift signal), never elapsed seconds.

Reboot = anesthesia: a global last-tick wall-clock stamp is persisted to a
sidecar (chrono_last_tick) in the data dir. engram_age_field_catchup() reads it
on boot, applies ONE cooling for the whole unconscious gap, refreshes the stamp,
and reports the magnitude — timestamps are bookkeeping to COMPUTE the drift,
never the felt signal. TC env-tunable via ENGRAM_CHRONO_TC (default 3600s).

All inert unless ENGRAM_CHRONOCEPTION is set → OFF path byte-identical.

MEASURED on a copy (throwaway HOME, TC=3600s):
- Cooling scales with dt, matching 1-exp(-dt/TC) to 1e-6: dt=600s->0.1535,
  1800s->0.3935, 3600s->0.6321, 7200s->0.8647.
- Scale-invariance EXACT: age(dt) once vs age(dt/N) N times gives identical
  field sum (|delta|=0.0) for N=2, 10, 100.
- Reboot catch-up over a 1h gap cooled the field 0.60->0.4415 in one shot,
  magnitude 0.6321, bounded in [0,1).
- Flag OFF: age & catchup return 0, field untouched (sum 1.2).
ASan+UBSan clean.

/* test_interoception_p2_chrono.c — M-INTEROCEPTION Priority 2.
* Chronoception: engram_age_field(delta_ms) + reboot catch-up
* (ENGRAM_CHRONOCEPTION, default OFF).
*
* Uses loaded snapshots with KNOWN working_memory_weight / background_activation
* so the field is deterministic without depending on activation. (engram_load
* halves WM on boot — the laundering step — so snapshot wm 1.0 -> 0.5 resident.)
*
* Modes:
* once <dir> <dt_ms> — age the field once by dt; save field.json.
* split <dir> <dt_ms> <N> — age by dt/N, N times; save field.json.
* (once vs split must match: scale-invariance.)
* catchup <dir> <gap_ms> — write a last-tick gap_ms in the past, then
* engram_age_field_catchup(); print MAGNITUDE.
* offcheck <dir> <dt_ms> — flag OFF: age returns 0 and field is untouched.
