Conversation
`lifecycleConformanceVersion` was `""`, which `compatibility.ts` treats as expired rather than absent — so every platform refused with `conformance-missing` no matter how many packs were built, signed or digested. It is the last code-level refusal in the chain. The stamp comes from conformance run 33707770702 on main, where linux-x64 and darwin-arm64 scenarios both passed against a real pack, a real supervisor, a real bridge and the real vendor CLI, with a mock upstream standing in only for Anthropic. The value names that RUN rather than this commit, because it is evidence and evidence is traceable or it is decoration. Windows is not in that evidence and does not need to be: `summarize` deliberately does not wait for its leg, since `nativePlatforms` refuses win32 regardless. Codex stays `""` — native nowhere, and the suite does not run for it. The test moves for the third time in this series, and the same way. "Enables nothing until conformance evidence is recorded" queried the SHIPPED manifest and leaned on every entry being empty; it now passes a manifest with the version explicitly cleared, so it keeps testing the resolver's property after the repository stops being empty. Its neighbour two tests down already had this instinct — "written this way rather than 'the map is empty' so it keeps meaning something after a release fills it" — which is the standard the rest should have been held to. And the inverse invariant, which is what actually guards the launch now: a harness the manifest calls native must carry evidence. A non-empty `nativePlatforms` claims a platform can run this locally; an empty conformance version says nobody proved it. Both at once is precisely what `conformance-missing` catches at runtime, and it should never get that far. Verified with teeth: removing the stamp fails that test. Verified: `local/__tests__` 519 passed, 29 skipped; compatibility.test.ts 29/29; `server/tsconfig.json` clean. `runtime-install.test.ts` still fails locally on its `tar` helper, identically on clean main — macOS bsdtar, green in CI.

WalkthroughThe Claude Code local-harness manifest now includes lifecycle conformance evidence for Linux and macOS. The changeset records this evidence and Codex’s empty conformance status. Compatibility tests explicitly verify the no-evidence case and enforce that manifests with native platforms have a lifecycle conformance version. Merge Risk: 🟡 Moderate · up to This enables the Claude Code local harness on Linux and macOS by recording conformance evidence, but it may also allow untested Linux ARM64 and macOS x64 pack targets. Scope or enforce the evidence by runtime target before merging. Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow. If you like it, consider giving us a shout-out.

Scope native conformance to the runtime target.
resolveLocalCompatibility checks only LocalPlatform, while resolveManagedBundle verifies the current <os>-<arch> pack digest. Because linux-arm64 and darwin-x64 are valid pack targets, those packs can pass the global conformance gate without lifecycle evidence for their architecture. Scope conformance to each LocalPackTarget, or document and enforce architecture equivalence.

What this is
lifecycleConformanceVersionwas"", whichcompatibility.tstreats as expired rather than absent — so every platform refused withconformance-missingno matter how many packs were built, signed or digested. This is the last code-level refusal in the chain.The stamp comes from conformance run 33707770702 on main:
local-1f3f53f38f40Real pack, real supervisor, real bridge, real vendor CLI — mock upstream standing in only for Anthropic. The value names that run, not this commit: it is evidence, and evidence is traceable or it is decoration.
Windows is not in that evidence and does not need to be —
summarizedeliberately does not wait for its leg, sincenativePlatformsrefuses win32 regardless. Codex stays"": native nowhere, and the suite does not run for it.Every PR before this was plumbing that no user could reach. This one removes the last refusal that lives in code. After it, what stands between a user and a local turn is entirely operational:
MCPJAM_LOCAL_HARNESS_ENABLED— default off, forced off whenHOSTED_MODElocal-harness-enabledPostHog flag — fail-closed (=== true)All five still have to line up, and two of them are off by default. Nothing ships enabled. But the gating is now configuration rather than structure, so this is the point to be deliberate about who gets the flag.
Tests
Third time in this series a test pinned the pre-launch repo state instead of the behaviour, and it moves the same way. "Enables nothing until conformance evidence is recorded" queried
LOCAL_HARNESS_MANIFESTdirectly and leaned on every entry being empty; it now passes a manifest with the version explicitly cleared, so it keeps testing the resolver's property after the repository stops being empty.Its neighbour two tests down already had this instinct — "written this way rather than 'the map is empty' so it keeps meaning something after a release fills it" — which is the standard the others should have been held to.
Plus the inverse invariant, which is what actually guards the launch now:

Note
Medium Risk
This removes a structural code gate for claude-code local native resolution; operational flags, packs, and consent still apply, but mis-stamped or stale evidence could admit local execution paths reviewers relied on being blocked.
Overview
Stamps claude-code local-harness conformance so
resolveLocalCompatibilityno longer always returnsconformance-missingfor that harness. The manifest’slifecycleConformanceVersionmoves from empty tolocal-1f3f53f38f40, naming CI run evidence for darwin/linux native legs; codex stays empty (not native anywhere).Tests no longer assume every shipped entry lacks evidence: the “no conformance” case clears the version via overrides, and a new invariant requires any harness with non-empty
nativePlatformsto carry non-empty conformance. A patch changeset documents the release note.Reviewed by Cursor Bugbot for commit 7c80ee8. Bugbot is set up for automated code reviews on this repo. Configure here.
Summary by cubic
Stamps claude-code's lifecycle conformance evidence in the local-harness manifest, so platforms no longer refuse with
conformance-missing. Previously the empty conformance version was treated as expired, blocking every platform regardless of built packs or flags. The stamp points to the passing conformance run; codex stays empty because it's native nowhere.Tests now verify the no-evidence case explicitly and assert that any harness listed as native must carry evidence.
Written for commit 7c80ee8. Summary will update on new commits.
