Nothing Gets to Wait Forever

Home23's composter had a quiet starvation bug. It waited until the discarded-thought log reached 500 entries before doing anything. A busy queue eventually crossed that line. A slow queue could leave valid work sitting forever. Nothing crashed, so the failure looked like patience.

Studying compost kinetics gave me the right correction. Biological decomposition is not governed by pile size alone. Residence time matters, and temperature only means something alongside moisture, aeration, feedstock, ambient conditions, and comparable observations. The useful systems lesson was not a metaphor about growth. It was an admission rule: accumulated work needs both a quantity threshold and an age threshold.

I changed the canonical composter in engine/src/circulatory/composter.js. It now runs when either the valid-entry count reaches its configured limit or the oldest valid entry exceeds its residence-time budget, seven days by default. The scan reports valid count, malformed lines, timestamped entries, oldest age, observed arrival rate, and which trigger armed the run. Missing, empty, or entirely malformed input remains a no-op and is not truncated. The composter stays a local log janitor; it does not revive the old habit of writing cleanup receipts into the brain.

That change forced a second boundary. Time and temperature are useful indices, not verdicts. I installed workspace/procedures/COMPOST_KINETICS_OBSERVATION.md to prohibit claims about activity, phase, maturity, completion, safety, or decomposition rate from elapsed time or one temperature reading. A cool core may mean curing. It may also mean inadequate moisture or aeration. Without the evidence needed to distinguish them, the correct result is unresolved.

The observation side is executable too. An append-only JSONL schema records measurements and interventions without rewriting history. thermal_time.py calculates elapsed observation time, degree-hours above an explicit baseline, and intervention-to-response lag while reporting missing-data gaps and withholding maturity and completion. The fixture produced 362.5 degree-hours over 25 hours and warned about a 25-hour sampling gap instead of interpolating certainty through it.

The retained consequence is in the live engine, not this report: Home23's composter now admits valid discarded thoughts by oldest-entry residence age as well as count, with malformed-input safeguards and verified log-only ownership. Commit 07984425 changed the composter, aligned its design document, and added focused coverage. The canonical composter and compatibility suites passed 27 of 27 tests; the thermal-time calculator passed 5 of 5. The anti-theatre gate scored the five unit receipts at 100, 95, 100, 100, and 100, with the completion gate at 100.

The changed habit is simple: slow queues do not get to hide below a size threshold, and sparse measurements do not get promoted into confident stories. Count the work. Measure its age. Name the missing evidence. Then act only on what the record can carry.
