A bounded bot read can miss a learned heal when earlier spellbook rows fill its limit. Add an exact Character-and-spell lookup and use it for membership, learning, and forgetting.

The paired playerbots change advances through healing rotations in bounded batches. Its durable regressions cover a late known heal, changed eligibility, large health values, and a completed missing result that permits movement during rescans. Separate cases cover fixture due times and navigation grid edges. Package PR: LyraCoreProject/packages#26.

Default Module library checks passed 1,523 tests. Pinned SpacetimeDB 2.7.1 generation matched all 1,000 Gateway binding files; this non-unique index produces no binding diff. Formatting passed. The clean paired correction passed 1,631 union library tests, 1,632 with debug reducers, all 37 real action and runner cases, two personality cases, and five core consent cases, including a populated preceding-Wasm upgrade. Paired Package CI is green. Final core CI also passed at 4f45007, including the full durable suite and default Gateway binding parity. Core #486 merged as e6a755d. The saved local Wasm SHA256 is c44a91ee92bb22ebce3de07e39caf9d7028794460a855c3b1d1f9329e473a2ae; runtime inputs record core a4b5518 and Package dba96bb. Independent Spec and Standards reviews are clear.

The final grid cleanup assertion also passed its focused durable run at core 4f45007 and unchanged Package dba96bb. It proves all nearby chunks are removed at both grid edges while a distant chunk survives. Both independent reviews cleared this test-only delta, and CodeRabbit marked its finding addressed.

The index preserves existing spell rows. Schema shipping remains subject to the repository's human review rule. No production realm was accessed.

Implemented and reviewed with GPT-6 Astra and GPT-5.6 Sol in Codex.

📝 Walkthrough

Walkthrough

The changes add a composite spellbook index and use it for membership operations. They also document Recovery Scan and add runner coverage for paging, revalidation, health comparisons, fixture isolation, navigation edges, and missing results.

Changes

Spellbook and recovery scan

Layer / File(s) Summary
Indexed spellbook membership
module/src/spell/spellbook.rs
PlayerSpell gains a composite (character_guid, spell_id) index. knows_spell, learn_spell, and forget_spell use indexed membership queries.
Recovery scan test harness
module/tests/playerbots_rewrite/runner.rs, CONTEXT.md
Runner snapshots include recovery-scan rows. New helpers stage fixtures, run passes, query scan state, and document the Recovery Scan states and behavior.
Recovery scan scenarios
module/tests/playerbots_rewrite/runner.rs
Tests cover paged scans, retained-row revalidation, large health ratios, fixture isolation, grid edges, and missing results while preserving other actions.

Priority: ⬇️ Low — Defer this change because it is a narrow playerbot recovery-read fix with indexed spell lookups and regression tests, without supplied evidence of broader product impact.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to a4b55

Recovery-scan coverage is expanded, but the navigation-edge regression does not verify that navigation was actually cleared. This leaves a bounded test-coverage gap for the fixture behavior.

Source review is clear for core a4b551893897c647b2cc1dfc6d7f1f2e2b375081 and Package dba96bb1a5366d5f779f1b66820931583f426419.

The independent standards review checked the core spell lookup, Recovery Scan glossary and row lifetime, explicit rotation identifiers, and separated regressions. No findings remain.

The independent specification review checked bounded scanning, retained-result validity, and foreground behavior. Its completed-negative rescan finding is fixed: a conclusive missing result permits useful work during later scans, and a later learned spell becomes eligible. The new regression checks both outcomes.

The reviewers covered Package 9e20aa66269c937cdd777a3cbf884837053c545e. The orchestrator reviewed the final workflow-only change to dba96bb against both axes. It pins the three current-core checkouts to the complete paired core revision and preserves immutable preceding migration inputs.

Default generation matched all 1,000 Gateway binding files, and the unchanged production core source passed 1,523 Module library tests. The full Package run and paired CI are still in progress; these source reviews do not claim their results.

Standards review used GPT-5.6 Sol; specification and orchestrator reviews used GPT-6 Astra in Codex.
