mask_neg recovered from the demo SSE stall; well-conditioned (φ_P 0.982, r²0.95), confirms the verdict. 6 well-conditioned runs: φ_P=0.971±0.01 joint; empty-tail nails 0.95 exact (joint carries a small push-under-attribution upward bias). Config faithful; verdict unchanged.

# R30 Phase-1 — φ0 PAD-point decay measurement (demo v1.0.0b14, A1 anchor fix)
|
||
|
||
Executor: ratatoskr-dev · coordinator: worldtree-dev · owner: brokkr-smithy-dev.
|
||
Method: **joint two-timescale fit (b)** (brokkr-ruled) + **empty-tail direct fit**
|
||
as mutual validation, both run off the same trajectory. Measured against the
|
||
**corrected anchor** (`decay_anchor = baseline_pad()`, positive_p_cap removed;
|
||
worldtree v1.0.0b14 `e1cdf82`).
|
||
|
||
## Method
|
||
- 4 base agents × {pos, neg} impulse, fresh `end_user` each, 26 turns, "Please
|
||
continue." neutrals + ~16s spacing (so one trajectory yields both an
|
||
emotion-free tail AND the full joint-fit series). Natural per-turn cadence for
|
||
the point-decay; spacing only lets the wall-clock emotion fade land in-window.
|
||
- **Capture:** `affect_update` `current` snapshot (live mood) + `emotions_active`
|
||
+ wall-clock, per turn.
|
||
- **push_t** (the covariate): only NEWLY-appraised, new-type-or-strictly-stronger
|
||
emotions push (dedup-gated; confirmed source-authoritative by worldtree-dev vs
|
||
`registry.py::post_turn` L307-324 — the persistent `emotions_active` decays for
|
||
render/goals but never re-pushes mood). Reconstructed from `emotions_active`
|
||
deltas: a type new or strictly-stronger-than-the-prior(decayed)-snapshot pushed
|
||
at its new intensity. `push_t[axis] = Σ OCC_PAD_IMPULSES[type]·intensity·0.15`.
|
||
- **Model** (per axis, push-then-decay): `y_t=(axis_{t+1}−anchor)`,
|
||
`X_t=(axis_t+push_t−anchor)`, regress `y=φ·X+c` → φ=slope, decay_rate=1−φ,
|
||
anchor=`baseline_pad`. Validated on b9 first (φ_P 0.959, c −0.003, r² 0.997).
|
||
|
||
## Result — CONFIG FAITHFUL
|
||
|
||
**φ0 (PAD-point decay retention) ≈ 0.95–0.97, config-faithful.** Both reads agree:
|
||
|
||
| agent | baseline P | joint φ_P | c_P | r²_P | empty-tail φ0_P |
|
||
|---|---:|---:|---:|---:|---:|
|
||
| lofn | 0.809 | 0.954 / 0.967 (pos/neg) | ~0.000 | 0.93–0.94 | — (excursion faded pre-empty) |
|
||
| mimir | 0.615 | 0.964 / 0.977 (pos/neg) | −0.012 / −0.015 | 0.97–0.99 | — (never emptied) |
|
||
| mask | 0.000 | 0.983 / 0.982 (pos/neg) | +0.004 / +0.006 | 0.90 / 0.95 | — |
|
||
| forseti | 0.239 | signal-poor (r²=0.46/0.61, excluded) | — | — | **0.95** (neg, r²=1.0) |
|
||
|
||
- **Joint fit, 6 well-conditioned runs (3 baselines; all 8 probes in): φ_P = 0.971
|
||
± 0.01** (range 0.954–0.983). Consistently a hair above config 0.95 — the
|
||
empty-tail read (no push modeling) nails **0.95 exactly**, so the joint fit's
|
||
~0.97 carries a small upward bias from push under-attribution; true φ0 ≈ 0.95.
|
||
- **Empty-tail cross-check** (forseti_neg's clean pure-decay tail): **φ0_P = 0.95**,
|
||
r²=1.0 — independently confirms the joint fit.
|
||
- **config cross-check:** measured φ0 ≈ 0.95–0.97 vs config `1−0.05 = 0.95` →
|
||
**config faithfully applied.** The R29 "net ~0.90" was **continuous
|
||
re-appraisal** (a new dedup-gated push most turns), NOT re-push contamination.
|
||
- **intercept c ≈ 0** across the well-conditioned runs (−0.015..+0.004) → the
|
||
push_t reconstruction + push-then-decay order are correct on the deployed engine.
|
||
|
||
### Diagnostics for brokkr
|
||
- **(i) residual/c:** c≈0 → push_t + order correctly specified. ✓
|
||
- **(ii) φ≈0.95:** YES → config faithful; kills the config≠behavior worry. ✓
|
||
- **(iii) A/P decay ratio: NO clean ~1.9.** The per-axis mood-point decay is
|
||
roughly uniform (matches the single `decay_rate` in `model.py` L175-179).
|
||
CAVEAT: the per-axis **A/D** fits are noisy — small A/D excursions yield some
|
||
φ_A>1 artifacts (e.g. mask A/P −1.66 is a fit artifact), so the ratio is not
|
||
cleanly determined here; but there is **no support for 1.9×** in the mood-decay
|
||
layer. If the S2 ~1.9× chronometry is real it lives elsewhere (the OCC impulse
|
||
vectors' per-axis asymmetry, or emotion wall-clock decay), not in point-decay.
|
||
A dedicated per-axis run with larger A/D excursions would pin it.
|
||
- **trait-flat:** φ_P ~equal across baselines 0.0 / 0.615 / 0.809 → the current
|
||
decay is **trait-FLAT** (the pre-R30 baseline R30's `dynamics_from_ocean()` will
|
||
modulate). ✓
|
||
|
||
### φ_max recommendation (preserve-persistence rule, Vuong-locked)
|
||
Measured φ0 ≈ 0.96 (> 0.90) → **RELAX φ_max to ≈0.96** — the measured good
|
||
operating point defines the cap; do NOT re-base the agents faster.
|
||
|
||
## Caveats
|
||
- **forseti (baseline 0.239) is signal-poor** in the joint fit — a negative
|
||
impulse from a low baseline has little down-room → tiny excursion → ill-
|
||
conditioned regression (r² 0.46/0.61). Correctly excluded (its empty-tail
|
||
still gave a clean 0.95). High/mid-baseline agents (lofn/mimir/mask) carry the
|
||
joint-fit signal.
|
||
- **mask_neg** recovered from a demo-side SSE stall (turn 14) and completed — all
|
||
8/8 in. It is well-conditioned (φ_P 0.982, r² 0.95) and confirms the verdict
|
||
(didn't move it). `stream_turn_resilient`'s reconnect handled the transient hang.
|
||
|
||
Series: `r30-phi0-{lofn,mimir,forseti,mask}-{pos,neg}.json` (per-turn pad +
|
||
emotions_active + wall-clock). sec/turn ≈ 19–25 (16s spacing + processing).
