Changelog

Version: 0.1.0
Date: 2026-09-02
  Major Features:
    - Added the Batch Request Combinator, which captures one circuit item request and stages its exact item-and-quality quantities across compatible requester chests before enabling loading.
  Features:
    - Added exclusive READY and COMPLETE circuit signals for loading control and managed-source completion.
    - Added Follow input and Snapshot input handling.
    - Added No tail flush, Single tail inserter, and Parallel tail inserters.
    - Added Abort batch and bounded automatic-tail retry recovery.
    - Added an explicit ARMED-and-zero maintenance action that previews and drains connected requester chests through temporary Trash unrequested control with verified restoration.
    - Added an optional per-combinator cleanup after Follow input returns to zero during REQUESTING, SETTLING, or READY; it drains only that batch's exact managed requester chests and is disabled by default.
  Gui:
    - Added the compact, modeless Factorio-native operating console with always-visible status and progress plus on-demand configuration, batch details, maintenance, diagnostics, errors, and recovery actions.
    - Added English and French localization with hover explanations for input and tail modes.
    - Added drain confirmation, amber progress, remaining-item reporting, and Stop draining controls.
    - Added an ARMED-only automatic-cleanup checkbox with a robot/storage consequence tooltip and a read-only active-batch value.
  Graphics:
    - Added the polished Batch Request Combinator thumbnail for the Mod Portal and in-game mod browser.
  Compatibility:
    - Added capability-based requester detection without hardcoded train-system, merged-chest, or requester prototype names.
    - Added current-version blueprint, copy, clone, and fast-replacement preservation for input sign, input handling, tail handling, and automatic-cleanup settings; older complete tags preserve their modes with cleanup disabled.
  Optimizations:
    - Added configurable staggered polling from 1 to 60 ticks with a default interval of 12, cached active-batch observations and item keys, direct recurring inserter-setting comparisons, bounded Single-tail planning, and no recurring GUI work while the panel is closed.
    - Reused requester points, inventory observations, validated hand results, successful cleanup state, and empty scheduler buckets while keeping requester-drain work off the idle path.
    - Kept automatic cleanup off the normal polling path; it performs no discovery, inventory scan, or requester write until an eligible interruption and then reuses the staggered DRAINING poll.
    - Kept Single-tail planning bounded as merged requester capacity grows and removed avoidable empty-map, inventory-snapshot, connector-lookup, and unchanged-error rendering work from recurring polls.
  Bugfixes:
    - Kept selected read-only configuration radios visibly checked without redundant Selected labels and reduced Start draining to the standard native green-button size.
    - Kept retained ERROR and ABORTED progress in the correct staged or loaded phase after loading had begun.
    - Removed owned requester sections before READY so loading cannot trigger replacement deliveries.
    - Prevented repeated chat notifications while the same combinator error remains unresolved.
    - Added fail-closed cleanup and recovery for replaced entities, changed wiring or settings, interrupted request transactions, and temporary stack overrides.
    - Added debug-mode automatic-inserter diagnostics with the exact failed rule, entity identity, unit number, and position.
    - Restored interrupted requester-drain leases before normal first-tick processing after load or configuration change and retained claims through every failed cleanup path.
    - Prevented conflicting saved requester-drain cleanup records from selecting or writing an unproven Trash-unrequested value.
    - Counted logistic-container trash slots during draining so cleanup cannot complete while uncollected items remain in the requester trash inventory.
  Info:
    - COMPLETE reports only that managed requester chests and monitored inserter hands are empty; destination or wagon capacity is not checked.
    - Automatic tail modes require one eligible READY-controlled inserter per managed requester chest with an empty hand and circuit stack-size and filter controls disabled.
