Asset-pack consumers previously selected origins and copied artifacts manually, so a target could declare remote content while still shipping it, or require an offline pack whose dependencies were missing. This PR adds opt-in assetPacks deployment policy and uses it in the target build pipeline.

  • Published @mpgd/target-config/asset-packs validates packaged/remote locations, resolves the complete offline-required dependency closure and creates a revision-pinned, once-encoded delivery URL resolver. Effective configuration includes the optional policy.
  • mpgd assets stage-target builds and verifies one target from its game-owned build config, emits disjoint packaged/remote roots, and reports actual asset and metadata bytes. Fresh outputs, source/output separation, link checks and configured byte caps prevent accidental replacement or inclusion.
  • Web, Capacitor, Apps in Toss and Devvit builds stage only the packaged objects before packaging and inspect the real asset namespace plus copied remote-only object digests. Embedded game namespaces are checked across their wrapper artifact. Experimental mini-game targets retain their existing package-local texture policy.
  • Add direct CLI fflate and yauzl runtime dependencies for staged delivery and sequential native-package inspection; Sampo minor changesets cover CLI and target-config. Omitted policies preserve existing builds.

Validation: full pnpm check; full package build and final CLI closure rebuild; new policy smoke (closure conflicts, source/output boundaries, symlinks, metadata, byte caps, nested namespaces, corruption and JSON output); installed tarball CLI/Phaser Chromium consumer with a separate static origin, first-launch offline-required closure and remote theme acquisition. Actual web staging, Apps in Toss wrapper staging and Android debug APK builds passed. The APK measured 7,272,966 bytes; its expanded local asset namespace was 62,328 bytes, with every packaged digest verified and all 43,301 remote-only object bytes excluded. This is build/consumer validation, not live store certification.

OCR delegate selection/rules plus host review covered all 20 changed files and the 4-file follow-up commit, including excluded tool/config/docs files (100%, no unresolved findings). File inventory catches byte-identical payload copies; transformed/embedded imports remain outside that check and source assets must stay outside Vite public/imports.

Review follow-up: validate the final remote output against the original canonical source and build config; perform the final web audit after generated icons; inspect complete APK/AAB/IPA or expanded iOS artifacts for hidden remote-only payloads; write remote deployment before release manifests/native success. New archive fixtures reject remote native resources and misplaced namespaces. A real Android APK also passed the new sequential entry audit. Prepared command coverage now includes all 55 commands.

References #173. Publication tooling and measured consumer evidence follow separately. Release PR #305 stays unmerged until all feature PRs finish.

Summary by CodeRabbit

  • New Features
    • Added per-target asset-pack delivery controls, including packaged and remote placement, offline-required packs, revision-pinned URL routing, and packaged-size limits.
    • Added a CLI command to stage asset packs for a target and report locations and byte totals.
    • Web-based target builds can now stage and validate configured asset packs; remote-only assets are kept separate from packaged output.
  • Bug Fixes
    • Added checks for asset integrity, placement, size limits, and accidental inclusion of remote-only assets in web and native build artifacts.
  • Documentation
    • Added guidance on configuring, staging, and validating asset-pack delivery.

📝 Walkthrough

Walkthrough

This change adds per-target asset-pack delivery policies, standalone staging and verification APIs, and CLI support. Target builds now stage packaged assets, write remote assets, and validate final artifacts. Smoke tests and browser scenarios exercise policy routing and packaged-versus-remote delivery.

Adds target staging, packaged and native artifact checks, and the assets stage-target command. Adds smoke coverage and includes it in the prepared CLI test group.
Target build integration
tools/target/build-target.ts
Builds and stages configured packs for supported targets, validates final artifacts, and writes remote assets and reports. Mini-game targets reject asset-pack policies.

.sampo/changesets/asset-packs-target-policy.md, docs/ASSET_PACK_DELIVERY.md, examples/asset-packs/README.md, examples/asset-packs/test/packed-consumer.mjs
Documents target policy and staging behavior. Adds browser scenarios for offline-required packaged assets and remote-enabled pack acquisition.

Targets that use asset packs can ship a local build-config path inside the web bundle's embedded target configuration. The stage-target command also gives a confusing error when the target name is misspelled or the target has no asset-pack policy. Both are small fixes. Neither blocks the core packaged and remote delivery flow.

I’m a rabbit with a pack to stage,
Grove stays close upon the page.
Dunes can travel from afar,
Hashes check each bundled star.
Policy guides my hopping route,
I nibble bytes, then bound about.

- Around line 1588-1590: Update the target policy lookup before
assertAssetPackTargetPolicy to distinguish an undefined target from a defined
target missing assetPacks. Throw a clear error naming ctx.values.target for each
case, and call assertAssetPackTargetPolicy only when the policy exists.

Review comments at @packages/target-config/src/effective.ts:
- Line 177: Update the assetPacks field in EffectiveTargetConfig and its
construction from input.platformTarget so the effective config contains only
delivery-policy fields and never includes the local buildConfig path; update the
effective-config smoke assertion to compare against the delivery policy without
buildConfig.
