Optional ReadonlydeepThe DEEP plateau tier's floor — deeper than the corpus-silent shallow floor, bought with TIME instead of level: the bin must hold DEEP_PLATEAU_FRAMES frames (~2 s) dip-free AND pshr-clean at this level. Feedback holds rock-steady for seconds; a played note decays, wavers or moves. Measured basis (rig, 2026-08-19): a hard ring's plateau sat at −25…−36 dBFS while the corpus-silent shallow floor bottoms at −24.
ReadonlygrowthConsecutive isGrowing frames required before the ramp route confirms (was GROWTH_CONFIRM_FRAMES).
ReadonlygrowthisGrowing's per-hop dip allowance, also the plateau route's no-decay bar (was GROWTH_MAX_DIP_DB).
ReadonlygrowthisGrowing's single-frame-share cap — the #106 attack rejector (was GROWTH_MAX_SINGLE_FRAME_SHARE).
ReadonlygrowthisGrowing's least-squares slope bar (was GROWTH_MIN_DB_PER_FRAME).
ReadonlygrowthisGrowing's end-to-end rise bar (was GROWTH_MIN_TOTAL_RISE_DB).
ReadonlypaprReadonlypersistReadonlyphprOptional Readonlyplateau#140 SATURATED-PLATEAU route floor (dBFS-ish). undefined ⇒ the route is OFF and
push takes only the ramp path (today's behaviour). Set > 0 sensitivity only.
ReadonlypnprReadonlypshrThe #116 sub-harmonic dB bar (was PSHR_MIN_DB) — PINNED in the LIVE pool at
every sensitivity, the lone gate subCleanFrames shortens the streak of but never
lowers.
ReadonlysubConsecutive sub-harmonic-CLEAN frames required (was the literal GROWTH_WINDOW_FRAMES streak in push). The pshr BAR itself is pshrMinDb; only this
required streak COUNT shortens with sensitivity.
Optional ReadonlytrendTREND route (opt-in, armed at s > 0 like the plateau tiers): a candidate whose dB
history CLIMBS this much end-to-end across the deep window (~2 s), every hop within
the dip allowance and pshr-clean throughout, is a run-away confirmed DURING growth —
however slow. The ramp route needs growthMinTotalRiseDb inside 5 frames (~12 dB/s
at s=1 live); a near-threshold ring regenerates far slower and used to reach the
plateau floors before anything fired (measured 2026-08-19: 48 frames candidate-clean
before the deep tier finally confirmed at −26 dBFS). Music that climbs steadily for
2 s while lone-tone-clean on every gate is a crescendo of a pure held note — the FP
corpus bounds the bar.
The full detector contract — every gate PersistenceTracker.push confirms on, promoted here from the module consts so a per-channel
sensitivitycan relax them (via thresholdsFor) without touching the corpus-tuned SAFE DEFAULT (DEFAULT_THRESHOLDS, built byte-for-byte from those consts). The first four are the historical instantaneous/persistence bar; the growth/sub-clean gates below were module consts until the FBS made detection operator-tunable. dB fields are in dB; frame fields are counts.
