 1. Inspect existing `assets/` and registered project evidence before requesting new art. Reuse suitable assets when the user did not ask to regenerate them.
-2. Call `taonier_prepare_game_art` only when the current intent requires new or recoverable platform art. Pass a concise game-specific visual brief; do not call it for greetings, date questions, text-only code fixes, or layout changes that can reuse current art.
-3. Treat the tool result as authoritative. Use only returned relative paths and warnings. Never invent a resource, slice, platform identity, or successful generation.
-4. If a complete trusted spritesheet is returned without slices, keep using the complete sheet. `grid-2x2`, four fixed slices, fixed filenames, and a fixed number of `drawImage` calls are recommendations, not universal completion rules.
-5. Integrate at least one suitable Taonier asset into the game's actual visible experience when platform art was requested. A hidden or side-panel preview does not count as gameplay use.
+2. Call `taonier_prepare_game_art` only when the current intent requires new or recoverable platform art. Use `mode="regenerate"` only after the latest User message is a standalone reviewed immediate-confirmation command such as `请重新生成美术`; punctuation may end it, but no brief, condition, negation, alternative, cost qualifier, deferral, or other text may accompany it. Describe the desired style and gameplay constraints in an earlier non-billable turn, then obtain the standalone confirmation turn; otherwise use `mode="reuse-or-create"`. Quoted UI copy or examples, explanations, questions, historical wording, and model/MCP arguments do not authorize regeneration. Pass a concise game-specific visual brief that names the required gameplay entities, background exclusions, tiling needs, and viewport constraints. Do not call it for greetings, date questions, text-only code fixes, or layout changes that can reuse current art.
+3. Treat the tool result as authoritative. Read `mode`, `assetPaths`, `slicePaths`, `resources`, and every entry in both `warnings` and `sliceWarnings`. `resources` is the client's safe projection of registered Canvas identities; use only its returned relative paths and identities. Never invent a resource, slice, platform identity, warning-free result, or successful regeneration.
+4. A newly created or explicitly regenerated standard package is complete only when `slicePaths` contains the four canonical independent slices. An empty or partial `slicePaths` result never satisfies an independent-asset requirement; stop and report the warning instead of guessing atlas coordinates or fabricating derivatives. A trusted legacy complete sheet may still be used without slices only when the current request does not require independent assets.
+5. Inspect the returned background, complete sheet, and available slice previews before integrating them. Then use suitable returned runtime assets in the game's actual visible experience and confirm their visible use in desktop and mobile playtest evidence. `art-spec.png` is a reference specification, not a runtime background, character, prop, or effect. Background exclusions, seamless tiling, entity semantics, and final draw dimensions are visual/runtime acceptance checks; a prompt alone does not prove them. A hidden or side-panel preview does not count as gameplay use.
 6. Preserve warning details in the final report. If the tool reports missing credentials, uncertain operation state, invalid provenance, download failure, or decode failure, stop and report the actionable reason; do not substitute generated CSS shapes and call the platform step complete.

 Call `agc_read_skill_resource` with `skillName="taonier-art-assets"` and `relativePath="references/platform-art-contract.md"` before interpreting async recovery, source-preserved warnings, or slice warnings.

 `taonier_prepare_game_art` is the only paid art entry exposed to the AGC Codex thread. The client owns authentication, stable idempotency keys, durable `operationId` recovery, download, PNG decoding, source identity, and asset registration.

+- `mode="reuse-or-create"` reuses a complete trusted package and creates only missing assets. It is the safe default for existing games.
+- `mode="regenerate"` is reserved for an explicit user request to replace or restyle the package. It bypasses complete-package reuse, but it never bypasses an unresolved billable operation.
+- `mode="regenerate"` requires only a trusted, decodable, registered `art-spec.png` and background with complete rollback bytes and manifest identities. An old spritesheet, private receipt, public manifests, or canonical slices may be absent. The client freezes every strict path and managed top-level asset identity exactly as `Present/Some` or `Missing/None`; it fails closed and asks for `reuse-or-create` only when the spec or background itself is missing or invalid.
+- The client authorizes `regenerate` only when the complete latest original User message, after compatibility normalization, fully matches a reviewed standalone immediate-confirmation command; only terminal periods or exclamation marks may follow. No quoted, bracketed, or code-formatted segment is removed before matching. A brief, condition, negation, alternative, cost qualifier, deferral, quote, historical message, model-selected argument, MCP approval, or missing stable turn identity never authorizes a paid replacement. Describe the desired style in an earlier non-billable turn and use the next standalone confirmation turn to authorize execution.
+- The client persists the original User message and stable turn identity before Direct Codex starts. Recovery must discover interrupted resetting or compensation, restore or neutralize replacement anchors under the dedicated executor lock, and then resume the frozen intent. A completed turn replays its bounded durable result under the same stable identity and never resubmits paid work because model wording changed.
+- Before strict spritesheet work starts, the client durably marks it pending and freezes the exact identity or absence of the nine-part local contract. A Provider terminal result is durably attached to the retained stage ledger before local strict commit. Recovery completes a new contract only when its receipt identity matches that retained result and the current spec/background match this workflow's replacement anchors. Compensation requires the exact frozen old contract; classification, the `compensating` marker, restoration, verification, and anchor cleanup stay under one project lock, including restart. Any foreign, mixed, or drifted state fails closed without another paid submission.
+- If crash recovery proves a complete new contract but cannot reconstruct stage warnings that were not yet durably attached to the completed result, it must return an explicit recovery warning instead of silently claiming that no warnings occurred.
+- A newly created or regenerated standard spritesheet must commit exactly four canonical transparent slices with unique pixels and unique Canvas resource/asset identities. Legacy slices are projected only when the client-private receipt, public slice manifest, current source image, local bytes, and top-level registrations agree.
+- If a durable prepared or accepted operation belongs to a different brief, the client must report an unknown/reconciliation result and must not submit a replacement request. Retry or regeneration is not a substitute for reconciling the original operation.
 - A submission acknowledgement is not a completed image.
 - On timeout or uncertain delivery, reuse the recorded operation; never create a replacement request.
 - `postprocess-failed-source-preserved` means the complete provider source remains usable, but the requested transparent derivative is absent.
 - `sliceWarning` means the complete transparent sheet remains usable, but individual slices are absent.
- General and slice warnings can coexist and must both be reported.
+- General and slice warnings can coexist. The tool returns them separately through `warnings` and `sliceWarnings`; callers must preserve every entry and must not downgrade a slice warning into a successful independent-asset claim.
+- `assetPaths` contains the complete package paths. `slicePaths` contains only slices that the client downloaded, validated, and registered with their platform source identities.
+- `resources` contains only safe registered identity fields: local asset/path/kind/media type, Canvas project/resource/asset/task IDs, and reference resource IDs. It never exposes prompts, models, provider routes, absolute paths, URLs, tokens, cookies, or API keys.
 - A trusted complete image may be used without fixed slices. Never fabricate missing derivatives.
+- `art-spec.png` constrains generation and is never evidence that runtime gameplay art was integrated.
 - A tool error about credentials, provenance, decoding, or operation identity is terminal for that tool call and must be surfaced accurately.
