Identifies stability filter as the cause (not rate limiting or threading)

Identifies float equality across ticks as the root cause

Quantises to integer matching device resolution

Target cardinality matches device states

Distinct value count shown (broken vs fixed)

Fixed targets are integers not floats

No fine-grained rounding in fix

Send-latest semantics: stale targets dropped not queued

Stability filter is consecutive-tick hold NOT rate limiting

Exact value match required for stability (quantisation trap)

Discrete target values not raw floats

Cloud min_interval default 1.2s

Stability ticks default 2

Tick rate default 0.4s

Bottom-up fill direction

Index inversion formula for top-indexed hardware

No enumerate anti-pattern

Explains enumerate produces wrong fill direction

Quantisation formula int(round(value * total))

Bottom-indexed formula also present
