Configurable artifact output path (output.distPath) landed in #296

[ScriptedAlchemy]

PR #296 (merge df52dc7) landed config-level artifact output support:

export default defineConfig({
  plugin: { ... },
  output: { distPath: 'artifact' }, // default 'dist'; CLI --output still wins
});

• Naming follows Rsbuild/Rslib output.distPath (string shorthand only).
• Values must be project-root-contained relative POSIX paths; AB4707/AB4708/AB4709 cover malformed shapes, root escapes/absolute paths, and reserved namespaces (.agent-bundle, .git, node_modules, src). Absolute paths stay a per-invocation CLI concern since the config is a hashed, portable release-identity input.
• The value is carried on PreparedProject.artifactDistPath (never the normalized model, so modelDigest stays location-independent) and feeds build/prepack, inspect, source-snapshot exclusion, the dev watcher ignore set, and the Workbench host-discovery doctor drift source that previously hardcoded <root>/dist.

Deliberately deferred, revisit only with real demand:

• per-asset-type distPath subdirs and output.filename templates (host-pack internals are framework-owned and content-addressed; no user-meaningful naming knobs exist)
• output.assetPrefix (artifacts are filesystem-installed, never URL-served)
• output.cleanDistPath

Docs: framework-mode config reference + diagnostics registry updated; scaffold templates carry a commented hint.

Verification on origin/main (2026-09-02, lane lane/tails-312-297) — every item in the body is landed and tested; closing.

Acceptance item	Evidence on main
output.distPath accepted in config (Rsbuild/Rslib name, string shorthand only)	packages/agent-bundle/src/config/validate.ts:1085-1126 (AB4707 shape, AB4708 root escape / absolute / .., AB4709 reserved first segment); packages/agent-bundle/src/config/normalize.ts:239-241
Carried as PreparedProject.artifactDistPath, not in the normalized model (location-independent modelDigest)	packages/agent-bundle/src/api.ts:343,744; packages/agent-bundle/src/dev/project-service.ts:61
Feeds build / prepack / inspect / dev / Workbench doctor drift source	src/build/rslib.ts:551, src/build/mcp-apps.ts:202, src/api.ts:787 (AB4706 overlap message names output.distPath), src/dev/coordinator.ts, src/dev/workbench-server.ts (artifactDistPath)
CLI --output still wins per invocation	packages/agent-bundle/src/cli.ts:547,557
Config validation tests	packages/agent-bundle/tests/package-conventions.test.ts:278-285 (AB4707/AB4708/AB4709 table)
Build output-location test (CLI → config → default precedence, on-disk directory, validate against the relocated artifact)	packages/agent-bundle/tests/api.test.ts:327-360 ("resolves artifact output with CLI, config, and default precedence")
Prepack honours output.distPath	packages/agent-bundle/tests/prepack.test.ts:43,52 (host-packs/cursor/INSTALL.md)
Docs	docs/framework-mode.md:177-197 (config reference, precedence, AB4706 interplay, Rsbuild naming note); docs/diagnostics.md:21 (AB4706–AB4709); packages/agent-bundle/README.md:19 pointer (lands with #396)
#319 artifact/ prepack default still coherent	output: { distPath: 'artifact' } is exactly how a project relocates the artifact out of dist/ to satisfy AB4706; framework-mode.md:194 documents that pairing

Branch check: wave/output-path holds no unmerged delta — its content is the squash of PR #296 (df52dc77f8d9ed16902493ad71e3b46d2668266f); git diff origin/main...wave/output-path on the relevant files is empty.

The "deliberately deferred" list in the body (per-asset distPath subdirs, output.filename, output.assetPrefix, output.cleanDistPath) was explicitly scoped out "revisit only with real demand"; nothing there was promised, so it is not reopened here.
