Summary

Gameplay-neutral performance fixes from Main spark profiles (2026-11-04). HandPickService.tick cost ~5.8 s/h on the main thread at 15+ players: a whitelist match for every player every tick (ItemsAdder/MMOItems lookups, Material.matchMaterial), a linear scan over every site for the reach check, and a mining-speed attribute read per player per tick.

• Held-tool cache: each player's main-hand whitelist match is reused until the stack changes (ItemStack equality against a stored copy), 20 ticks pass, settings reload, or the pack-plugin matcher is rebound. The tick loop and the HUD share one match. The legacy lock strip still runs once per new stack, in the same tick as before.
• Mining-lock reads: while the lock is confirmed absent, the attribute is read again at most every 20 ticks. Locking is unchanged (applied at once, read every tick while locked). The saved unlock state is dropped on rejoin, quit and character switch.
• Chunk index: SiteRepository.findByChunk / hasEstablishedIn use a world+chunk index, rebuilt whenever the set of sites changes. Status is read live. If two ruins share a chunk, the old lookup order is kept. Ranges wider than 64 chunks still use the full scan.
• Estate pass timing: the startup pass still runs 3 ticks after enable. The hourly passes now start at 1h15m instead of 1h, so they no longer share a tick with other plugins' hourly jobs.

Not changed: the per-cut dossier save in resolveCut stays synchronous with its fsync, to keep the crash ordering of the ownership journal and the dossier.

Behaviour notes

• The first estate pass after a restart can run up to 15 minutes later, once.
• If something outside Archaeo re-adds archaeo:no_vanilla_mine to a player not holding an excavation tool, it can stay on for up to 19 ticks (before: 1). No such code exists today.

Tests

• 822 tests. The only failures are the 3 SiteEstatesTest cases that also fail on unmodified main on Windows (Linux CI is authoritative).
• New tests cover held-match reuse and rematch (stack change, in-place change, 20-tick recheck, settings reload, matcher rebind), the shared match between a hold and the HUD, the unlock re-read window, forget on quit and character switch, chunk index invalidation (add, delete, erase, reload, failed first save, shared chunk, int-limit ranges), and the estate timer schedule.

Test plan

• Dev: HUD and lock on/off when aiming at fill, opened air, sky; swapping items; renaming or damaging the held pick
• Dev: cling/clang timing, on-time single lift, late multi lift, work day and tool wear unchanged
• Dev: HUD appears and disappears at the same reach as before; /archaeo reload and iareload while holding the tool
• Dev: spark shows no per-tick DigTools.match or hasEstablishedIn in HandPickService.tick

Dev test

Dev (TFMCDev01, 11-05): HUD and mining lock follow the held item (hotbar switch, in-place replace, plain vanilla pickaxe) within the 1 s check; reach across a chunk edge correct; dig cycle (late, on-time cuts, work days) normal; /archaeo reload and /iareload keep it working. No new warnings.

Summary

Summary by CodeRabbit

• Bug Fixes

  • Hand Pick state is now cleared when a player quits or switches character, even if cleanup fails.
  • Vanilla mining is unlocked when the held item is not an excavation tool and restricted only during relevant Hand Pick actions.
  • Estate checks now run at startup and then hourly, with the first hourly check 75 minutes later.

• Performance

  • Excavation-tool matching and site lookups are cached or indexed to reduce repeated work. Changes to tools or loaded sites are reflected in subsequent lookups.

The pull request adds per-player Hand Pick caches and cleanup, indexes site lookups by world and chunk, and changes the timing of estate passes.

Changes: Hand Pick state

Layer / File(s)	Summary
Held-tool and mining state cache src/main/java/net/tfminecraft/archaeo/excavation/HandPickService.java, src/test/java/net/tfminecraft/archaeo/excavation/HandPickServiceTest.java	The service caches held-tool matches and mining-unlock checks per player, with 20-tick recheck intervals. Tests cover cache reuse, refresh conditions and shared use by hold and HUD processing.
Cache updates and player cleanup src/main/java/net/tfminecraft/archaeo/ArcheologyPlugin.java, src/main/java/net/tfminecraft/archaeo/excavation/HandPickListener.java, src/main/java/net/tfminecraft/archaeo/excavation/HandPickService.java, src/test/java/net/tfminecraft/archaeo/excavation/HandPickListenerTest.java	Tool matcher changes clear cached matches. Quit cleanup forgets player state even if finishing fails, and character-session end also clears that state.

Site repository chunk index

Layer / File(s)	Summary
Chunk index, lookups and invalidation src/main/java/net/tfminecraft/archaeo/site/SiteRepository.java, src/test/java/net/tfminecraft/archaeo/site/SiteRepositoryTest.java	The repository uses a versioned world-and-chunk index for chunk lookups and small established-site range queries. Loaded-site changes invalidate the index. Tests cover lookup ordering, status changes, reloads, removals and failed saves.

Estate pass schedule

Layer / File(s)	Summary
Startup and hourly pass timing src/main/java/net/tfminecraft/archaeo/ownership/SiteEstates.java, src/test/java/net/tfminecraft/archaeo/ownership/SiteEstatesTest.java	The estate pass runs three ticks after startup. The hourly schedule begins 75 minutes and three ticks after startup. Tests verify these times and later hourly intervals.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Moderate · previous review 08b8c

Moving a stored site can leave chunk lookups stale and prevent Hand Pick excavation at its new location. Fix location-change invalidation before merging, or explicitly accept this limitation.

Test the refreshed matcher result.

Change the matcher result while the held stack remains unchanged. Assert that the mining lock or HUD reflects the new result at expiry. The current test could pass with a stale cached profile.

Test cache reuse after restoration changes the stack.

The mocked restoreAllowedTool does not change the stack. The test cannot detect a pre-restoration snapshot that causes another match and restoration on the next tick. Add a test with a mutating restoration and verify reuse on the following tick.
