Changelog

Version: 0.22.13
Date: 2026-07-24
  Bugfixes:
    - Fixed saves failing during on_configuration_changed because the unified fleet registry read the removed LuaEntityPrototype.max_health member.
    - Switched runtime hull calculations to LuaEntity.max_health, which is the supported quality-aware maximum-health value in Factorio 2.0.
    - Audited and corrected the same invalid prototype-health access in Mega Drone recreation, refitting, servicing, commissioning, and carrier repair-mission scanning.
  Compatibility:
    - Storage schema remains 24 and remote API remains 22.
    - No save migration is required from 0.22.12; updating to this version allows affected saves to load normally.

Version: 0.22.12
Date: 2026-07-24
  Changes:
    - Replaced the permanent Skybound Journey dismissal behavior with a reversible Hide action that preserves the current goal and all Journey progress.
    - Repurposed the existing Ctrl+Shift+J control and shortcut-bar button to show the current Skybound Journey again; completed Journeys and Guidance Off open the Help Log directly.
    - Renamed the shortcut to Skybound Journey and Help Log, changed Open Help to Open Help Log, and added a Show Journey button inside the Help Log.
    - Hidden-state notices now display the player's configured Journey control instead of requiring a console command.
  Migration:
    - Storage schema 24 converts saves dismissed by 0.22.10 or 0.22.11 into hidden Journeys and recovers all uncompleted stages without erasing completed progress.
  Compatibility:
    - Remote API remains 22. Existing 0.22.11 saves migrate automatically.

Version: 0.22.11
Date: 2026-07-24
  Changes:
    - Clearly tells the player immediately after dismissing the Skybound Journey that the entire proactive sequence is hidden and can be restored with /skybound-guidance-reset.
    - Repeats the restoration command whenever a player loads or rejoins a save where the Journey remains dismissed.
    - Allows every player to restore their own Journey without administrator privileges; targeting another player still requires administrator privileges in multiplayer.
  Compatibility:
    - Storage schema remains 23 and remote API remains 22.
    - No save migration is required from 0.22.10.

Version: 0.22.10
Date: 2026-07-24
  Changes:
    - Changed the Skybound Journey dismiss button to dismiss the entire proactive Journey sequence instead of advancing immediately to the next guidance card.
    - The Help Library and Journey progress checklist remain available after dismissal.
    - Resetting Skybound guidance restores the proactive Journey sequence.
  Compatibility:
    - Storage schema remains 23 and remote API remains 22.
    - No save migration is required from 0.22.9.

Version: 0.22.9
Date: 2026-07-24
  Bugfixes:
    - Fixed the Shuttle HUD repeatedly logging an error when Factorio returned the currently burning fuel as a quality-aware item/prototype object instead of a plain string.
    - Normalized runtime item identifiers before constructing localized item-name keys or inventory snapshots.
    - Clamped the Shuttle HUD to a compact fixed width and disabled inherited horizontal stretching so Flat UI, GUI Unifier, and similar global GUI-style mods cannot expand it into a screen-spanning bar.
    - Shortened the takeoff and landing button captions while preserving the key binding in the hint and tooltip.
  Compatibility:
    - Storage schema remains 23 and remote API remains 22.
    - No save migration is required from 0.22.8.

Version: 0.22.8
Date: 2026-07-23

  Performance:
    - Reduced Shuttle, Engine I Shuttle, wreck, and Dock sprite-frame area by 23.4% without resizing visible artwork.
    - Removed the separate sparse Shuttle turret/sensor render layer; directional sensor details remain baked into the body art.
    - Changed Shuttle presentation sprites from high to medium cache priority and enabled hardware-aware forced downscaling.
    - Reduced loaded Shuttle directional atlas area from 4,259,840 to 2,458,624 pixels, a 42.3% reduction.
  Compatibility:
    - Rendering-only optimization. Storage schema remains 23 and existing saves require no migration.

  Features:
    - Replaced the Worn Survey Shuttle with a rugged industrial frontier-VTOL visual identity.
    - Added distinct final art for the Engine I Shuttle variant, Shuttle wreck, matching icon family, and Shuttle Dock alignment pad.
  Polish:
    - Strengthened Factorio-style steel plating, exposed machinery, cargo-hatch readability, landing skids, hazard markings, cyan navigation lights, and field-repair asymmetry.
    - Preserved the existing 64-direction, one-frame-per-direction vehicle presentation.

Version: 0.22.3
Date: 2026-07-23
  Bugfixes:
    - Fixed Space Age generated recycling recipes being assigned nonexistent dynamically constructed Skybound icon paths during final data fixes.
    - Final icon replacement now uses a generated registry of the 207 icon files actually packaged with the mod.
    - Generated or third-party Skybound-named prototypes without dedicated artwork preserve their existing inherited icon metadata.
  Validation:
    - Audited every explicit __golden-age-skybound__/ asset path in Lua source against the packaged files.
    - Validated every packaged PNG and Ogg asset and every dynamically constructed final entity, icon, and sound path.
  Compatibility:
    - Storage schema remains 23; no save migration is required from 0.22.2.

Version: 0.22.2
Date: 2026-07-23
  Bugfixes:
    - Fixed the Worn Survey Shuttle failing data-stage validation because its one-frame final animation inherited the vanilla tank's two-frame light_animation.
    - Removed incompatible inherited tank light animations from the Worn Survey Shuttle, upgraded Shuttle variant, Shuttle Dock, and Shuttle Wreck after final-art replacement.
    - Added explicit one-frame declarations to the final Shuttle and turret animation layers.
  Compatibility:
    - Storage schema remains 23; no save migration is required from 0.22.1.

Version: 0.22.1
Date: 2026-07-23
  Bugfixes:
    - Fixed the Fleet Command Array radar prototype failing during data-stage loading because its final-art RotatedAnimation layer did not declare direction_count.

Version: 0.22.0
Date: 2026-07-23
  Features:
    - Entered formal M22 feature freeze and added release-candidate validation for art, audio, guidance, accessibility, localization, compatibility, packaging, migrations, benchmarks, and multiplayer acceptance.
    - Replaced permanent Skybound prototype icons with original project-specific icon art and added final visual bindings for aircraft, Airports, Hangars, Beacons, Docks, the Fleet Command Array, and operational markers.
    - Added original event-driven aircraft, infrastructure, operation, contract, procurement, and alert sound cues with per-player category volume, deduplication, aggregation, and cooldown controls.
    - Added the contextual Skybound Journey, first-use goal cards, four guidance modes, and a permanent Help Library covering the complete Shuttle-to-Fleet-Command progression.
    - Added final accessibility settings including Reduced Motion, independent audio categories, optional Critical sounds, and GUI alternatives for major controls.
    - Added ReleaseValidationManager, FeedbackManager, GuidanceManager, migration 023, remote diagnostics API 22, release commands, sanitized diagnostics export, and compatibility-certification records.
    - Added final thumbnail, art and audio bibles, asset provenance, README, FAQ, compatibility matrix, known issues, credits, release checklist, post-release backlog, portal description, and package manifest.
  Changes:
    - Updated the Skybound storage schema to version 23.
    - Updated the development version to 0.22.0; version 1.0.0 remains reserved for a build that passes live clean-install, migration, benchmark, Golden Age, GUI-scale, and multiplayer acceptance testing.
    - The Aviation Guide shortcut now opens the contextual Help Library.
    - Presentation work obeys M21 rendering, GUI, audio, and deterministic simulation budgets.
  Validation:
    - Static package validation covers Lua parsing, module dependencies, runtime require placement, event and constant references, input and locale conflicts, final asset paths, release documents, archive root, duplicate entries, and ZIP integrity.
  Info:
    - Live Factorio data-stage loading, migration fixtures, balance playthroughs, benchmark runs, Golden Age certification, and dedicated multiplayer soak testing remain explicit 1.0 promotion gates.

Version: 0.21.0
Date: 2026-07-23
  Features:
    - Added deterministic shared work-unit scheduling with Critical reserve capacity, stable priority queues, starvation credit, resumable cursors, revision safety, cancellation, and backlog telemetry.
    - Added dirty-record deduplication, reciprocal relationship indexes, spatial buckets, registered-entity records, active-aircraft indexes, and deterministic commissioned-zone monitoring shards.
    - Moved Development Zone planning, manifest generation, Skyway graph scope rebuilds, reconciliation, transaction repair, storage maintenance, and multiplayer audit hashing into bounded scheduler jobs.
    - Replaced all-pairs Skyway node comparison with force/surface-scoped spatial candidate searches and deferred graph rebuild jobs.
    - Added incremental save reconciliation, transaction reconciliation, corruption quarantine, safe recovery actions, force-merge recovery, and managed-surface deletion handling.
    - Added bounded route-cache eviction, history and sample pruning, three-plan superseded retention, completed-operation compaction, request/tombstone expiry, and absent-player transient-state cleanup.
    - Added the Performance Console, performance profiles, global workload settings, per-player refresh/rendering settings, manager and scheduler dashboards, storage telemetry, backlog alerts, and multiplayer audit hashes.
    - Added Standard, Large, Extreme, and multiplayer soak scenario harnesses plus M21 audit, benchmark, soak, and release-readiness documentation.
    - Added migration 022, remote diagnostics API 21, M21 debug commands, validation, localization, and documentation.
  Changes:
    - Updated the Skybound storage schema to version 22.
    - Performance profiles affect deterministic throughput and local visual detail only; they do not select gameplay outcomes.
    - New automatic operations temporarily pause during critical reconciliation phases while active safety and value-moving work continues.
  Validation:
    - Parsed all 508 Lua files and all 9 JSON files successfully.
    - Resolved all 1,858 literal module dependencies with zero dependency cycles and zero control-stage runtime require() calls.
    - Completed mocked initialization, configuration change, 1,200 lifecycle ticks, Critical-before-Background scheduler behavior, request deduplication, and revision-conflict checks.
  Info:
    - Real Factorio UPS benchmarks, data-stage loading, existing-save migration, and headless multiplayer soak/desync testing remain required release-candidate gates because Factorio was unavailable in the implementation environment.

Version: 0.20.1
Date: 2026-07-23
  Bugfixes:
    - Fixed a non-recoverable startup crash caused by GoldenAgeAdapterManager calling require() during on_init.
    - Removed all 19 runtime require() calls from control-stage code across Golden Age integration, contracts, procurement, gemstone avionics, Fleet Console, remote API, Defense planning, Transport planning, and debug commands.
    - Moved every affected dependency to file-scope loading during control.lua parsing, as required by Factorio 2.0.
  Validation:
    - Parsed all 482 Lua files successfully.
    - Verified zero require() calls remain inside runtime functions.
    - Verified all 1,750 literal module dependencies resolve and the module graph has no dependency cycles.
  Info:
    - Storage schema remains 21 and remote API remains 20; no save migration is required from 0.20.0.

Version: 0.20.0
Date: 2026-07-22
  Features:
    - Added optional Golden Age `gold-ore >= 2.0.0` compatibility while preserving the complete standalone M0-M19 progression path.
    - Added versioned runtime handshake, partial-capability negotiation, stable provider registration, Exchange-stage and Treasury summaries, and Fleet Console compatibility reporting.

    - Added persistent contract verification and payout transactions that prevent duplicate coin or Standing rewards across retries and save/load.
    - Added Royal Air Supply catalog registration and six Quartermaster aviation stock templates.
    - Added explicit Treasury procurement policies, per-order caps, cycle percentage limits, minimum reserves, physical delivery targets, partial delivery, refunds, and manifest inbound accounting.
    - Added the Gilded Avionics Core and two physical gemstone sockets for verified Rough or Cut Ruby, Sapphire, Emerald, and Diamond carrier specialization.
    - Added gemstone transaction rollback, duplicate-gem diminishing returns, module-damage dormancy, safe refit restrictions, configuration validation, force-merge reconciliation, and physical wreck recovery.
    - Added Golden Age Fleet Console dashboards, Unified Operations, deadline priority, economic alerts, remote API 20, branch adapters, debug commands, migration 021, localization, validation, and documentation.
  Changes:
    - Updated the Skybound storage schema to version 21.
    - Golden Age remains authoritative for coins, Treasury, Exchange progression, procurement, contract-board state, gemstone prototypes, and economic history owned by Golden Age.
    - Skybound remains authoritative for aircraft, routes, missions, Development Zones, physical delivery proof, carrier configuration, gemstone socket assignments, and Royal Aviation Standing.
    - Automatic Treasury spending remains disabled by default and requires explicit player-approved allowlists and spending caps.
    - Accepted Royal contracts and procurement orders now appear in Fleet Command without competing for aircraft independently of their linked physical operations.
  Info:
    - The optional full contract, procurement, and accomplishment feature set requires the companion Golden Age runtime API extension described by M20; unsupported capabilities degrade independently.
    - Live Factorio 2.0 testing with Golden Age installed and absent, multiplayer, save/reload, removal/reinstallation, and physical delivery transactions is still required before public release.

Version: 0.19.0
Date: 2026-07-22
  Features:
    - Added Fleet Command and Autonomous Operations technology and the force-wide Fleet Console.
    - Added copied unified asset and operation registries for aircraft, infrastructure, zones, schedules, missions, manifests, construction, commissioning, supply contracts, recovery work, and Transport Corridors.

    - Added Critical, High, Normal, Low, and Background priorities with parent, zone, group, contract, and force inheritance, bounded queue aging, visible safety bonuses, and deterministic tie-breaking.
    - Added deterministic Modular Carrier and Large Cargo Drone assignment with module, capacity, route, source, health, energy, congestion, reservation, emergency-reserve, and group-policy evaluation.
    - Added complete assignment explanations including eligible candidates, rejected candidates, score factors, penalties, revisions, and selected-asset reasoning.
    - Added multi-drone Transport Corridor assignment, replacement provisioning, reciprocal corridor ownership, authoritative revalidation, and safe-boundary release.
    - Added force policy profiles, operation concurrency budgets, queue admission reasons, queued-only and safe-boundary preemption, reassignment, and persistent deferred-release handling.
    - Added transactional pause, resume, recall, Emergency Recall, Emergency Pack, safe cancellation, and group commands with stable targets and per-target results.
    - Added unified alert deduplication, severity, escalation, acknowledgement, temporary and policy suppression, resolution, root-cause relationships, downstream effects, recommended actions, and explicitly enabled safe automation rules.
    - Added bounded assignment, operation, commissioning, failure, recovery, alert, and command history.
    - Added the optional 7x7 Fleet Command Array with a 500 MJ command-power buffer and load-dependent 5 MW, 10 MW, or 20 MW draw.
    - Added force-merge handling for M19 policies, groups, alerts, rules, command transactions, Command Arrays, and history.
    - Added migration 020, remote API 19, M19 debug commands, validation, localization, and documentation.
  Changes:
    - Updated the Skybound storage schema to version 20 and preserved all M1-M18 aircraft, infrastructure, routes, flights, cargo, robots, missions, schedules, contracts, Development Zones, construction operations, and Material Corridors.
    - Reserved Ctrl+Shift+F for the Fleet Console and moved the older Freight Schedule shortcut to avoid an input conflict.
    - Specialized managers remain authoritative; Fleet Console commands use Mainframe requests and cannot directly mutate physical system records.
    - Automatic assignment never targets planning, manifest, staging, commissioning, manual-deployment, or ground-only Transport operations that do not require an aircraft.
    - Supply-contract carrier assignments now release after their physical child mission reaches a terminal state.
  Info:
    - M19 coordinates player-approved operations and does not approve plans, redesign factories, procure materials, choose technologies, or create hidden strategic goals.
    - Live Factorio 2.0, multiplayer, save/reload, GUI, and long-running congestion testing is still required before public release.

Version: 0.18.0
Date: 2026-07-22
  Features:
    - Added Autonomous Transport Engineering and the Material Corridor Console for approved Transport Development Zones.
    - Added a force-aware Transport Port registry for commissioned Mining outputs, Smelting inputs and outputs, Cargo Hangars, selected endpoints, and compatibility-registered custom ports.

    - Added belt-lane sizing, connected source and destination buffer adapters, underground protected crossings, Cargo Hangar handoffs, Large Cargo Drone sizing, multi-destination air allocation, and corridor-owned Freight Schedule definitions.
    - Added exact Transport manifests, phase-aware carrier packing, autonomous belt and handoff construction, owned Cargo Hangar construction, physical Large Cargo Drone deployment, and idempotent schedule provisioning.
    - Added physical, power, ground, air, hybrid, and sustained-flow commissioning that observes real endpoint inventories and real Cargo Hangar transfer statistics.
    - Added commissioned Material Corridor monitoring for source starvation, destination blockage, ground disconnection, Hangar power, drone shortages, stranded drones, paused schedules, bottlenecks, capacity limits, and expansion recommendations.
    - Added migration 019, remote API 18, Transport overlays, save/load ownership reconciliation, multiplayer-safe Mainframe events, debug commands, localization, validation, and implementation documentation.
  Changes:
    - Updated the Skybound storage schema to version 19.
    - Extended Cargo Hangars, Large Cargo Drones, Freight Schedules, generic manifests, carrier packing, and autonomous construction with optional Transport Corridor ownership.
    - Commissioned Mining and Smelting ports can now be connected by persistent, physically constructed Material Corridors.
  Info:
    - Fluids, trains, cross-surface routes, mixed-item corridors, multi-source balancing, automatic demolition, and global logistics optimization remain deferred.

Version: 0.17.0
Date: 2026-07-21
  Features:
    - Added the complete Smelting Zone planner with one to four independent recipe lines, supported base and registered modded solid smelting recipes, four planner profiles, four furnace-bank geometries, and four throughput target modes.
    - Added force-aware furnace, belt, inserter, pole, buffer, fuel, radar, and module registries with deterministic throughput, furnace-count, lane, inserter, power, fuel, source-capacity, startup-stock, and buffer calculations.
    - Added distinct mirrored-bank, parallel-bank, modular-cell, and compact-block candidates with real input, output, and fuel routes, physical ports, service access, expansion reservations, scoring, preview, comparison, validation, approval, and staleness handling.
    - Added exact Smelting construction manifests, real startup input and burner fuel, phase-aware carrier packing, dependency-ordered construction, module installation, startup loading, and generic zone-pipeline integration.
    - Added physical, configuration, electrical, fuel, input, output, warmup, and sustained-production commissioning using actual output flow and furnace production counters.
    - Added commissioned Smelting Complex readiness monitoring for physical integrity, furnace availability, input starvation, burner fuel, electrical service, output blockage, recipe behavior, and measured throughput.
    - Added automatic, manual-approval, and alert-only Fuel Supply Contracts targeting real cache inventories through ordinary carrier supply missions.
    - Added Autonomous Smelting Engineering technology, Smelting Console and overlay controls, marker prototypes, remote API 17, debug commands, migration 018, localization, validation, and documentation.
  Changes:
    - Extended the generic planner, manifest, staging, packing, construction, and commissioning pipeline to Smelting Plans while preserving Mining and Defense behavior.
    - Smelting plans create nearby physical handoff ports but do not construct long-distance inter-zone transport corridors; that remains reserved for M18.
    - Burner and electric operation remain distinct: burner lines require real compatible fuel and delivery, while electric furnaces and powered logistics require a real electrical connection.
    - Storage schema is now 18. Existing M1-M16 aircraft, routes, carriers, missions, zones, Mining and Defense plans, manifests, operations, outposts, readiness records, and supply contracts are preserved.
  Info:
    - M17 creates working industrial conversion complexes, not decorative furnace rows. Actual in-game and multiplayer launch testing is still required before public release.

Version: 0.16.1
Date: 2026-07-21
  Bugfixes:
    - Fixed the Defense Supply Contract marker referencing the nonexistent Factorio base icon path logistic-chest-requester.png. It now uses the valid requester-chest.png icon, allowing the mod to load.

Version: 0.16.0
Date: 2026-07-21
  Features:
    - Added the complete Defense Zone planner with protected assets, access corridors, sixteen threat sectors, player overrides, five defense geometries, four planning profiles, and ballistic, energy, or mixed equipment packages.
    - Added deterministic scored Defense Plan candidates with walls, gates, turret coverage and crossfire, radar, power, local ammunition caches, physical belt feeds, maintenance stock, optional mines, and exact startup supplies.
    - Added Defense Plan manifests, physical staging, carrier packing, dependency-ordered autonomous construction, real ammunition loading, and electrical-grid validation through the generic M13-M15 zone pipeline.
    - Added strict gate, access, coverage, ammunition, power, radar, cache, belt-feed, and controlled live-fire commissioning.
    - Added commissioned Defensive Outpost readiness monitoring, attack-history retention, breach detection and markers, entity rediscovery, and Defense Readiness Console overlays.
    - Added Defense Supply Contracts for ammunition, repair stock, actual plan-derived replacement parts, and mixed resupply through normal carrier supply missions.
    - Added Autonomous Defensive Engineering technology, Defense selection tool, marker and test-target prototypes, remote API 16, debug commands, validation, multiplayer authority checks, and migration 017.
  Changes:
    - Refactored planner, manifest, packing, construction, phase, and commissioning dispatch by plan type while preserving Mining Zone behavior.
    - Gun-turret plans require physical ammunition logistics; laser-turret plans require real electrical connection; all commissioned outposts require radar and maintenance stock.
    - Defense planning and construction remain deterministic and bounded, and never create free permanent structures or supplies.
    - Storage schema is now 17. Existing M1-M15 aircraft, routes, carriers, missions, zones, mining plans, manifests, depots, construction operations, and commissioned Mining Outposts are preserved.

Version: 0.15.0
Date: 2026-07-21
  Features:
    - Added autonomous Mining Zone construction operations using locked approved plans, manifests, carrier packing plans, and configuration revisions.
    - Added transaction-safe physical loading from Zone Supply Staging Depots and approved Airport inventory sources.
    - Added normal Skyway dispatch, Landing Beacon anchoring, isolated mobile roboport deployment, real cargo externalization, and native construction robots.
    - Added bounded expansion of approved placements, compressed belts, tiles, removal operations, settings, modules, and component dependencies.
    - Added Foundation, Obstacle Removal, Power Backbone, Output Depot, Trunk Logistics, Collection Logistics, Mining Equipment, and Finishing construction phases.
    - Added save-resumable resupply trips, returned-cargo reconciliation, ghost persistence, manual-build recognition, and destroyed-placement restoration.
    - Added strict physical, electrical, mining-logistics, drill-coverage, output-port, and extraction commissioning.
    - Added persistent Mining Outpost built-entity records, status monitoring, Construction Operations UI, overlays, remote API 15, commands, validation, and migration 016.
  Changes:
    - Construction uses only physical staged, loaded, recovered, or manually supplied materials and never creates free items.
    - Approved plan coordinates remain immutable throughout construction; conflicts pause dependent work rather than removing player structures automatically.
    - Carrier cancellation and failure paths preserve completed infrastructure and safely return or retain real cargo whenever possible.
    - Storage schema is now 16. Existing M1-M14 aircraft, missions, zones, surveys, plans, manifests, reservations, depots, and packing plans are preserved.

Version: 0.14.0
Date: 2026-07-21
  Features:
    - Added exact phase-aware Zone Material Manifests generated from approved Mining Plans.
    - Added deterministic construction-item resolution for planned entities, compressed belt segments, underground endpoints, splitters, poles, depots, modules, tiles, and terrain operations.

    - Added the physical 5x5 Zone Supply Staging Depot with 256 inventory slots, Airport attachment, power interface, manifest binding, and bounded Airport transfer.
    - Added source inventory scanning, soft-reservation ledgers, physical staging, exact quality-aware quantities, and stale-manifest reconciliation.
    - Added phase-first, minimum-trip, and critical-path carrier packing simulations with exact stack sizes, cargo slots, trip limits, and construction phases.
    - Added independent plan, material, staging, carrier, infrastructure, and packing readiness dimensions.
    - Added the Zone Material Manifest console, staging-depot interface, manifest map overlay, remote API 14, debug commands, validation, localization, and documentation.
    - Added migration 015 and storage schema 15 while preserving every M1-M13 aircraft, mission, Development Zone, survey, reservation, and Mining Plan record.
  Changes:
    - Planned Mining Zones can now enter manifesting, awaiting-materials, and ready-for-construction states without beginning construction.
    - Physical Staging Depot inventories are authoritative; manifests only store calculated snapshots and never duplicate staged items.
    - Optional reserves and startup supplies remain separate from exact mandatory plan materials and do not block readiness unless explicitly required.
    - Construction remains unavailable until the next milestone; no carrier is dispatched and no ghosts or entities are placed in M14.

Version: 0.13.0
Date: 2026-07-21
  Features:
    - Activated the first autonomous industrial planner for approved and reserved Mining Development Zones.
    - Added deterministic Balanced, Maximum Coverage, Compact, and Throughput profiles with one to five candidate layouts.
    - Added force-aware equipment selection for supported mining drills, matched belts, underground belts, splitters, power poles, output containers, and inserters.
    - Added resource-grid analysis, single-resource and explicit compatible mixed-resource planning, drill placement, collection and trunk belt routing, output handoffs and depots, power distribution, access clearances, no-build areas, scoring, and validation.
    - Added persistent Mining Plan, component-group, placement, output-port, removal-operation, metric, validation, approval, staleness, and supersession records.
    - Added Mining Planner settings, candidate comparison, player-local previews, approval, revalidation, output and power pins, and protected-area tools.
    - Added bounded underground-belt crossings for narrow protected corridors and water, plus planned tree, rock, cliff, and landfill operations without changing the world.
    - Added provider-depot availability checks, explicit existing-handoff validation, optional radar/lamp/repair-buffer extras, and complete power-coverage revalidation.
    - Added remote API 13 Mining Planner queries, generation, approval, revalidation, regeneration, and equipment registration.
    - Added migration 014, M13 debug commands, planner validation, documentation, and localization.
  Changes:
    - Mining planner capability is now available while all other Development Zone planners remain survey-only.
    - Approved Mining Zones enter the planned state after one candidate is approved and retain their existing reservation.
    - World, boundary, survey, equipment, access, exclusion, and preserved-infrastructure changes mark the approved plan stale rather than silently moving placements.
    - The hidden Development Zone marker remains a non-colliding interaction anchor and is not treated as physical reserved land; real Airport, Landing Beacon, carrier-approach, and player exclusion clearances remain protected.
    - Updated storage schema to 14 and remote API version to 13.
  Info:
    - M13 generates complete persistent plans only. It does not create ghosts, reserve or consume materials, dispatch construction carriers, or build the outpost.

Version: 0.12.5
Date: 2026-07-21
  Features:
    - Added the four-step Development Zone flow: Choose Purpose, Mark Area, Review Survey, and Approve Site.
