Why

The runtime image size gate started failing on the rc.3 Version Packages branch (#7485): 7545 MiB against a 7424 MiB limit. Every prerelease cut adds a full schema bundle (~140 MiB) plus compliance and tarball artifacts, and .dockerignore re-includes dist/schemas, dist/compliance, and dist/protocol, so the image had accumulated 101 schema versions (~5 GB). rc.2 passed with 66 MiB of headroom; rc.3 and every later cut would fail.

What

Retire the superseded 3.x beta checkpoints from the three dist mounts.

Mount	Before	After
dist/schemas + dist/compliance + dist/protocol	6340 MiB	4491 MiB

Kept on purpose, with the reason each is load-bearing:

• 3.2.0-beta.11 schemas: the frozen 3.2-beta documentation selector. The Addie docs indexer requires dist/docs/<v> and dist/schemas/<v> for every selector in the Mintlify nav and throws otherwise.
• 3.2.0-beta.6 schemas and compliance: the training agent's retained checkpoint (SELLER_GOVERNANCE_DISCOVERY_ADCP_VERSION), asserted by tests/sdk-runtime-compat.test.cjs.
• 3.1.0-beta.7 schemas and compliance: @adcp/sdk's sync-schemas:3.1-beta side bundle, fetched during prepublishOnly.

Supporting changes:

• dist/schemas/index.json regenerated from the surviving directories (91 → 71 versions); no alias pointed at a removed version.
• static/compliance/published-versions.json: removed betas dropped from published_versions; 3.1.0-beta.2, which the current @adcp/sdk package still ships, moved to package_only_versions so check-published-compliance-versions stays green.
• scripts/check-immutable-release-artifacts.cjs: whole-tree deletion of a tagged -beta.N version is now permitted; in-place edits and any deletion of rc/stable artifacts still fail. Tests added for both.
• scripts/check-immutable-release-artifacts.cjs and scripts/check-changeset-protocol-scope.cjs: git diff --name-status now runs with a 64 MiB maxBuffer; the default 1 MiB buffer crashed both scripts (ENOBUFS) on this 27k-file diff, and the guard runs in CI's build-check.
• Docs: 14 schema links pointing at 3.2.0-beta.0 and 3.2.0-beta.10 bundles repointed to 3.2.0-rc.2 (all targets verified present); versions.mdx legend and the beta.0 row now describe the retirement.

Public URL impact

None expected. adcontextprotocol.org/schemas|compliance|protocol/* are served by the Cloudflare artifact worker from the R2 bucket with immutable caching (verified: beta bundle URLs return 200 with server: cloudflare). The R2 backfill helper deliberately refuses --delete, so previously published beta objects stay in the bucket. The versions page now states beta URLs are served best-effort only.

Not in this PR

• dist/docs beta snapshots (about 235 MiB, allowlisted in .dockerignore) and the frozen 3.2-beta docs selector itself. Retiring those touches the release-docs nav tooling and is a separate decision.
• The sustainable fix, moving historical bundles out of the runtime image entirely, is still worth an issue; this buys roughly 1.9 GB, about 12 prerelease cuts of headroom.

Validation

• node tests/immutable-release-artifacts.test.cjs
• node --test tests/published-compliance-versions.test.cjs tests/dist-schema-version-ids.test.cjs tests/sdk-runtime-compat.test.cjs
• node scripts/check-published-compliance-versions.cjs
• node scripts/check-immutable-release-artifacts.cjs origin/main and node scripts/check-changeset-protocol-scope.cjs origin/main
• npx vitest run tests/addie/cross-publisher-frequency-docs.test.ts (the test that caught the beta.11 selector dependency)
• npm run test:unit (71 files, 1063 tests) and npm run typecheck
• pre-push: version sync, changeset policy, lint:schema-links, docs navigation. The local storyboard matrix was skipped with ADCP_SKIP_STORYBOARD_MATRIX=1; CI runs it.
• Not run locally: the pre-commit server unit suite (precommit:server-unit, up to 25 minutes); CI runs it.

Ladon verdict: Escalate to human review

Escalate — deletions inside immutable released dist/** artifacts plus a governance policy decision require human review.

This PR retires the 3.1.0-beta.0 release artifacts, deleting ~90+ files under dist/compliance/3.1.0-beta.0/**. The repo's LADON.md declares that dist/compliance/<semver>/ paths are append-only release records that are immutable after GA, including -beta.N paths — modifying/deleting a file inside an existing semver artifact is normally critical. Retiring immutable released beta artifacts is a protocol-policy decision the reviewer explicitly deferred to the arbiter, and it is not something Ladon should auto-clear.

Two independent escalation triggers apply:

• The high-risk flag is set and every high_risk_reasons entry is a (deleted) under dist/** (decision table row 3 → escalate).
• The change is a governance/policy decision about release-artifact immutability that warrants explicit human/CODEOWNERS ratification, and review_decision is REVIEW_REQUIRED (not APPROVED).

Escalation reasons

• Deletes 90+ files under dist/compliance/3.1.0-beta.0/** — removal of immutable released artifacts; adopters may pin these paths. Requires human confirmation that retiring this beta line is sanctioned.
• Policy decision to retire released beta artifacts should cite/establish governance precedent and be ratified by a human, not auto-approved.

Medium finding (non-blocking, note for reviewers)

• scripts/check-immutable-release-artifacts.cjs:69 — isRetiredPrereleaseDeletion permits any single-file deletion inside a -beta.N tree despite advertising whole-tree deletion; a future partial deletion of a retained load-bearing beta would pass CI silently. Tighten to require whole-tree removal.

Why human review

• Deletes 90+ files under dist/compliance/3.1.0-beta.0/** — removal of immutable released release artifacts (append-only after GA per LADON.md); needs human/CODEOWNERS confirmation.
• Retiring released beta artifacts is a governance/protocol-policy decision the reviewer explicitly deferred to the arbiter; review_decision is REVIEW_REQUIRED, not APPROVED.
• high_risk is true and all high_risk_reasons are (deleted) entries under dist/** — decision-table row 3 requires escalation.
