# Score, statistics and recipient lifecycle batch

RE-747–756 continues from `ae4d61e7`, with ten separately committed tasks. The goal remains the complete game in Rust with Bevy/Solari on macOS and Linux. This batch recovers additional source contracts and three Rust simulation primitives; native parity and interactive gameplay remain open.

| Task | Verified scope | Evidence |
| --- | --- | --- |
| RE-747 | Complete205260 score gates, wrapping and rank requests | [Score](QVM_SCORE_UPDATE.md) |
| RE-748 | Complete6369/6439 recipient gates and loops | [Notifications](QVM_CLIENT_NOTIFICATIONS.md) |
| RE-749 | Complete278733 method/stat-slot classification | [Slots](QVM_METHOD_STAT_SLOTS.md) |
| RE-750 | Complete278834 counters, self aliases and follow-up requests | [Counters](QVM_METHOD_STAT_UPDATES.md) |
| RE-751 | Complete285486 cross-client clearing and inclusive64 bound | [Clearing](QVM_CROSS_CLIENT_CLEAR.md) |
| RE-752 | Protected completion with actual score/reset-loop children | [Protected composition](QVM_PROTECTED_RESOLVED.md) |
| RE-753 | Interception with actual scoring, notification, stats and clearing | [Interception composition](QVM_MODE10_RESOLVED.md) |
| RE-754 | Pure Rust wrapping score updates and rank intent | [Rust score](RUST_SCORE_UPDATE.md) |
| RE-755 | Pure Rust method classification and wrapping counters | [Rust counters](RUST_METHOD_STATS.md) |
| RE-756 | Pure Rust cross-client clearing with exact logical write parity | [Rust clearing](RUST_CROSS_CLIENT_CLEAR.md) |

205260 updates client248 unless no client or a paused-state global blocks it. Mode3 without team suppression also updates the indexed team score. Arithmetic wraps; ranking5864 is requested after active mutation. The origin argument is unused. Rust rejects unsupported team indices only when the source would index team storage.

6369/6439 require nonnull, in-use entities and client pointers, then select connection state2 recipients from a6336-stride array. Callback recipient entity pointers use an880 stride. The loops are recovered; recipient179736/180087 internals remain captured. The fixtures cover four supplied client states and bounded counts rather than live network allocation.

278733 uses the original jump table to map19 methods into slots0..18. Complete278834 applies per-slot or fallback counters, with distinct self cases and wrapping increments. Its aggregation/report children279720/279586/285227/283622 remain explicit boundaries. Invalid victim/null-page domains remain unverified. The Rust port uses typed actor/victim counter ownership, validates storage before mutation and returns reporting intent.

285486 visits64 entity slots, skips null clients and clears one pair in each remaining record. The index gate accepts64 inclusively, requiring65 pairs in the Rust representation. The Rust adapter compares every changed logical word, including sparse rows, invalid indices and mode gates; unit tests also check untouched neighbors, empty rows and idempotence.

Protected and interception compositions now execute the recovered child bodies. Original event allocation is supplied; logs, commands, ranking, recipient callback internals and stat aggregation/reporting remain captured. The composition uses explicit valid pool ID aliases; this does not close full health/contact/runtime integration or native binary parity.

## Validation cadence

Focused `cargo xtask test-group` runs precede every task commit, with deterministic report regeneration and storage/link/whitespace guards. The shared-health regression passed101 Python tests while preserving prior reports. Rust parity groups run scoped gameplay package tests. After commit ten, the single `cargo xtask test-full --since ae4d61e7` run passed1443 Python tests and68 Rust tests (10 assets,30 gameplay,28 xtask). Twenty-one affected report producers regenerated twice byte-identically; storage, documentation links across315 files and whitespace guards passed. Generated reports matched committed outputs and the tree was clean. This documentation-only result is recorded by amending the tenth commit.

## Remaining limits and next tasks

1. Recover ranking5864, including ordering/ties, score publication and dependencies.
2. Recover recipient179736/180087 internals and actual notification serialization/state effects.
3. Recover279720/279586/285227/283622 aggregation/reporting children and establish matrix/counter lifetime ownership.
4. Compose actual protected152386 from health mutation, including threshold completion with null attacker and original low-page data behavior.
5. Compose all recovered lifecycle children from full211239 and original-model contact, then shared293732 and successful295018 pellet aggregation.
6. Replace numeric counter offsets and callback intents with owned Rust runtime state/events while preserving the recovered numeric contracts.
7. Port inventory reset and obituary serialization, prove real callback registrations and connect model animation clips.
8. Continue native18183 loader/library ownership and original executable/DLL runtime parity.
9. Connect simulation, asset VFS and world collision to macOS/Linux Bevy runtime validation.
10. Port rendering/materials to Solari and validate interactive full-game acceptance on both platforms.

RE-746 remains partially advanced. No new claim of native, Linux, rendering or full gameplay completion is made by these finite source/Rust contracts.
