Realm-core validates replay ordering, rejects conflicting active promotions, and stores durable promotion receipts. Gateway bindings, cleanup paths, documentation, and tests cover propagation and lifecycle behavior. ChangesLoot roll promotion

- Around line 812-873: Enforce the upgrade checkpoint before publishing by
rejecting promotion while any outstanding active or staged loot rolls remain,
including legacy rows with Identity::ZERO; alternatively, add a complete
migration that safely drains or migrates every such roll. Update
accept_promotion and the surrounding rollout path so old Realm-core rolls cannot
resolve without a promotion receipt or unlock the corpse before settlement.

Integrated merged #468. The tested Module, Gateway, Loot Roll fixtures and pinned CLI are byte-identical after the rebase. The Binding fixture correction now lets the full CI suite run. @coderabbitai review |

game_loot_roll_promotion_receipt.
accept_promotionuses theby_source_slotindex, andcleanup_rollremoves only active roll and vote rows. The documented contract retains each receipt after resolution, with no expiry or bounded retry window, so storage can grow with distinct source, corpse, and slot keys. Define a capacity target and expose row-count and growth metrics. Do not delete receipts based on corpse age or a retry window until the promotion contract rejects every delayed request for that key.🤖 Prompt for AI Agents

Rebased onto merged party cleanup The combined loot recorder retains the nonzero item property, promotion source and source roll ID. The new deleted-Character fixture supplies that source identity. All 1,323 Gateway unit tests and 119 integration/parity checks pass, with the previously documented local trace-path failure excluded. Strict all-target/all-feature Gateway lint, formatting and diff checks pass. CI and review are restarting on this commit. Human schema approval remains pending. @coderabbitai review |

The maintainer reviewed the schema at The PR is ready for review. I will merge after current-commit CI and CodeRabbit review finish and any findings are resolved. |

A delayed Loot Roll START could recreate the roll and its votes after resolution.
Promotions now carry the source Module identity and staging row id. Realm-core retains the greatest accepted id for each source, corpse and slot. Replays succeed without recreating rows; a later generation can reuse the slot after resolution. The selected Random Property and exact staging cleanup id survive retries.
Refs #441. Integrates approved #462 and merged CLI #58.
The pinned publish command checks every intended destination before any publish. Legacy rolls, votes, withheld loot, unreadable state and malformed results prevent the batch. The Operator must first stop new loot producers, let old Gateways finish settlement, then stop those Gateways and keep the destinations quiescent through publish. The CLI checks state; it does not stop gameplay or lock multiple Shards together.
Local validation passed. The current Gateway integration includes merged Character party cleanup. CI checks the current commit:
8a40989proves that empty roll/vote tables can still hide withheld loot. Old settlement delivers one item. Additive publish then preserves that item, property 117 and source sequence, refuses old START arguments and stamps new staging rows with a nonzero identity.Human schema review was approved on 2026-09-07 for the appended default-ZERO Identity field after the approved property field, private receipt table, reducer arguments, generated bindings and upgrade procedure. The schema, Module, bindings and upgrade procedure remain identical in current commit
034079a. Receipts have no TTL and grow with distinct source identities, corpse guids and slots. Restoring an older source under the same identity requires separate review.Only owned disposable Standalone fixtures were used.
