feat: add Contextivity ACP and permanent nightly distribution - #1
Conversation
ACP CLIs such as Contextivity can be configured as first-class instances instead of impersonating Grok. The new driver reuses AcpSessionRuntime, keeps Grok's x.ai extensions isolated, and omits T3 MCP unless the agent advertises HTTP MCP. DECISIONS: - Duplicate a standards-only adapter in new files so the patch can later be deleted without a GrokAdapter refactor - Keep Grok/Cursor MCP policy at always; generic uses auto/never - Document native Agents panel and available_commands as limits rather than inventing a Contextivity-only subagent protocol
ACP Registry advertises a namespaced extension and maps negotiated `_contextivity/subagent_event` payloads onto canonical task.* events so child agents populate the existing Agents panel. Malformed notifications are ignored and never fail the primary turn. Agents without matching _meta keep tool-activity-only behavior. CHALLENGES: - Strict ACP SDK schemas would fail the turn on malformed notifications; handlers use Schema.Unknown plus a local parser. - Producer wire is snapshot/delta; the T3 brief listed per-lifecycle kinds. Parser accepts both. DECISIONS: - Advertise client _meta always; ingest only when agent _meta is v1. - Dedicated parser and mapper modules rather than growing the adapter. - Child agentId is task identity, not TaskAgentLinkage.agentId. - Cursor and Grok ignore the new runtime event tag.
Contextivity finalized `_contextivity/subagent_event` as snapshot/delta with bounded records and no per-child usage. Drop draft kind aliases, identity truncation, and invented usage so T3 matches that wire. CHALLENGES: - Mixed malformed records cannot be skipped: an empty snapshot would cancel the live roster. Reject the envelope instead. - A later summary patch keeps terminal state, so the mapper must treat change=updated after terminal as progress, not a second completion. DECISIONS: - Parser matches producer v1: snapshot|delta, started|updated|terminal, records[], snapshot 64 / delta 8 / lineage 8, identity rejection. - Extra usage fields are ignored, never mapped onto typedUsage. - Client always advertises _meta v1; ingest only when agent _meta is v1.
Official clients must keep seeing the exact T3 nightly version, so the fork cannot publish or install the public npm t3 package. This pipeline tracks official pingdotgg/t3code nightly tags, builds attested per-platform server archives, and promotes only after the Mac desktop version matches. DECISIONS: - Keep fork/updater machinery under contextivity/ so the ACP patch stack stays reviewable on its own - Dual identity: protocol serverVersion stays the upstream nightly; contextivityRevision is install-path only - Candidate GitHub releases are immutable and separate from nightly and stable fleet pointers
Authoritative snapshots over 64 records were truncated, so the mapper cancelled children that were only missing because of the cap. Change "terminal" also completed tasks that were still running. Reject oversized snapshots whole, and require a terminal state or terminal object before emitting completion.
Real fleet activate never ran inventory restart or health commands, so rollback only existed in mocked tests. Direct t3-ctx fleet also skipped the exact Mac desktop version gate, and candidate manifests accepted a partial platform set. Pass each host's restart and health commands through remote activate with bounded execution, fail closed without a verified Mac version, and require exactly the four server platforms. Manifest hashes stay the updater's source of truth; SHA256SUMS remains a published sidecar.
SSH concatenates remote argv without re-quoting, so multi-word restart and health commands were split before the remote t3-ctx parsed them. Send those strings as base64url tokens and decode them on the remote CLI so the original command reaches sh -c intact.

validated alias, followed by "t3-ctx" and the provided args; keep the local
command path unchanged. Update the corresponding test expectation to match the
new SSH argument order.
In `@contextivity/src/git-runner.ts`:
- Around line 11-20: Update conflictPaths so its primary conflict-line regex
absorbs the whitespace after the colon before the optional “Merge conflict in ”
text, ensuring content-conflict lines capture only the actual path. Remove the
redundant colon regex and preserve handling for other conflict formats and
deduplication.
In `@contextivity/src/github-auth.ts`:
- Around line 54-74: Update resolveGitHubEndpoints to validate every configured
mirror override before returning the resolved api or base: parse each effective
URL, reject malformed values, embedded credentials, and non-HTTPS schemes, while
allowing only an explicit loopback exemption if supported by the existing
policy. Preserve default endpoints when no overrides are set and retain the
trusted-mirror requirement for configured overrides.
In `@contextivity/src/inventory.ts`:
- Around line 65-75: Update the sshAlias validation in the inventory host
parsing flow to accept only safe SSH config alias characters, rejecting values
beginning with option prefixes or containing shell/control characters and other
unsupported syntax before hostArgv uses them. Preserve the existing empty,
user@host, and URL checks and the ssh transport requirement.
In `@contextivity/src/spawn.ts`:
- Around line 80-84: Attach an error listener to child.stdin before the
stdin.end calls in the spawn flow, handling write/close failures such as EPIPE
without allowing an uncaught exception; keep the existing child process error
handling and input/no-input behavior unchanged.
- Around line 48-79: Update runBoundedHostCommand so timeout handling escalates
from SIGTERM to SIGKILL after a short grace period, ensuring the promise settles
even when the child ignores termination; clear both timers on process completion
or error. Also cap accumulated stdout and stderr while preserving the existing
result and timeout behavior.
- Around line 17-38: Update runBoundedHostCommand to prevent caller-supplied
command text from being executed through sh -c; validate restart and health
command inputs at the CLI boundary, including base64-decoded variants, or
replace shell text with fixed commands plus separately validated arguments
before invoking spawnCommand.
In `@contextivity/src/updater.test.ts`:
- Around line 111-153: Add a test for stageCandidate with GitHub authentication
where verifyAttestation returns a non-zero exit code, and assert that staging
rejects with the attestation-verification failure. In the same test, capture and
validate the arguments passed to verifyAttestation, including the expected
repository and attestationVerifyArgs values; keep the existing missing-verifier
and successful-verification cases unchanged.
In `@contextivity/src/updater.ts`:
- Line 227: Remove the unconditional NodeFS.chmodSync call from the activation
flow in updater.ts; preserve operator-configured permissions on
input.layout.root, applying 0o755 only during directory creation if that
creation path requires an explicit mode.
- Around line 177-194: The version-directory lifecycle can delete an install
referenced by current and rollback can activate a missing previous directory. In
contextivity/src/updater.ts lines 177-194, update the staging flow around
formatInstallId and versionDirFor to reject an installId matching the active
install, or stage extraction in a temporary sibling and rename it into place
only after preflight succeeds. In contextivity/src/updater.ts lines 231-246, add
a versionDirFor(layout, previous) existence check before swapping symlinks,
consistent with the activateStaged guard; both sites require direct changes.
- Around line 231-246: Update rollbackCurrent to verify that the previous
version directory exists before calling atomicSymlink, reusing the same
existence-check behavior or helper used by activateStaged; keep the swap and
return behavior unchanged when the target exists. Ensure a failed rollback
preserves the original activateAndVerify error when invoked from its catch path,
rather than replacing it with the rollback error.

Minor comments:
In `@apps/server/src/provider/acp/ContextivityAcpExtension.ts`:
- Around line 327-337: Update the redaction pattern in boundedText so sensitive
keywords followed by whitespace, such as “Bearer” or “token”, redact the
subsequent value in addition to colon- and equals-delimited forms. Preserve the
existing normalization, placeholder, and truncation behavior.
- Around line 322-325: Update boundIdentity to trim string input before
validating its length and returning it, so whitespace-only identifiers are
rejected and valid identifiers use the trimmed value.
In `@apps/server/src/provider/Layers/AcpRegistryAdapter.test.ts`:
- Around line 774-786: Replace the timed Effect.sleep and polling loop in the
interrupt test with synchronization on the stream’s turn.started receipt, then
invoke adapter.interruptTurn only after that event is observed while the first
prompt remains active. Preserve the existing cancellation assertions and use the
stream receipt as the sole readiness signal.
In `@apps/server/src/provider/Layers/AcpRegistryAdapter.ts`:
- Around line 1398-1414: Update the ProviderAdapterRequestError construction in
respondToUserInput to replace the copied provider-specific method name with a
provider-neutral value, while preserving the existing unknown-request handling
and pending-input resolution behavior.
In `@contextivity/inventory.example.json`:
- Line 9: Update the restartCommand values in the inventory examples to use $(id
-u) instead of $UID, ensuring they expand correctly when executed through POSIX
sh -c and preserve the gui/<uid>/com.example.contextivity-t3 target.
In `@contextivity/src/args.ts`:
- Around line 24-32: Update the argument parsing logic around the token loop and
flags map so a following token beginning with “-” is consumed as the current
flag’s value unless it matches the parser’s actual flag shape; preserve
separate-flag handling for valid flag tokens and positional-argument behavior
otherwise.
In `@contextivity/src/config.ts`:
- Around line 67-72: Update FORBIDDEN_UPSTREAM_PACKAGE_PATTERNS to match
forbidden t3 package invocations both with and without a version suffix, while
preserving the existing npx, npm, pnpm, and vpnpm command variants and their
boundaries.
In `@contextivity/src/fleet.test.ts`:
- Line 400: Update healthCommand in the fleet test to write a test-controlled,
deterministic value instead of expanding the potentially unset HOME environment
variable, and update the assertion near the marker-content comparison to expect
that same value.
In `@contextivity/src/git-runner.ts`:
- Around line 45-47: Update abortMerge to propagate failures from the
git(["merge", "--abort"], cwd) invocation instead of swallowing them, matching
the error behavior of the other runner methods.
In `@contextivity/src/identity.ts`:
- Around line 52-69: Update parseInstallId to lowercase the captured
contextivity revision before returning it, matching assertRevision normalization
and ensuring mixed-case install IDs compare consistently in promoteCandidate;
leave formatInstallId and other parsing behavior unchanged.
In `@contextivity/src/mac-client.ts`:
- Around line 10-12: Update the plain-version branch in the Mac client version
parsing logic to pass the validated trimmed value through normalizeVersion
before returning it, matching the other branches. Preserve the existing null
behavior for invalid versions and ensure all successful branches use the same
normalization path.
In `@contextivity/src/manifest.ts`:
- Around line 170-183: Update decodeManifest’s compatibility validation after
the existing requiresExactClientVersion check to require
compatibility.officialMacDesktop to equal the expected gating value
"must-match-upstreamVersion", rejecting any other value before the builder can
rewrite it.
In `@contextivity/src/promote.ts`:
- Around line 112-129: Update buildChannelPointer to validate input.promotedAt
before calling toISOString; reject unparseable timestamps with a clear, typed
error consistent with this module’s fail-closed behavior, while preserving ISO
formatting for valid values.
In `@contextivity/src/release.ts`:
- Around line 137-148: Update decodeChannelPointer to use the existing
parseJsonObject helper instead of JSON.parse with a Record cast, ensuring null
and other non-object inputs receive the intended validation handling. Preserve
the existing channel, installId, and candidateTag validation flow.
In `@contextivity/src/write-candidate-manifest.ts`:
- Line 55: The CLI path in writeCandidateManifest must accept a --created-at
option and pass it as createdAt; when omitted, derive createdAt from a
reproducible upstream commit timestamp instead of new Date().toISOString().
Preserve explicitly supplied timestamps and ensure identical tag/revision inputs
produce identical manifest bytes.
In `@docs/operations/contextivity-downstream.md`:
- Line 135: Update the fenced code block near the shown layout example to
specify the text language, using the existing path content unchanged and
preserving the block’s formatting.

Nitpick comments:
In @.github/workflows/contextivity-candidate.yml:
- Around line 210-222: Update the “Write candidate manifest” step to remove the
unused SHA environment variable, add upstream_commit to env, and pass the
resulting shell variable to --sha instead of expanding
needs.sync.outputs.upstream_commit inline. Keep the remaining manifest arguments
unchanged.
In `@apps/server/src/cloud/selfUpdate.ts`:
- Around line 34-39: Make contextivityDistribution required in the input type of
resolveServerSelfUpdateCapability, then update every call site, including make,
ServerEnvironment, and the contextivityDistribution test, to pass an explicit
boolean so omitted values cannot bypass the guard.
In `@apps/server/src/distribution/contextivityDistribution.test.ts`:
- Around line 11-18: Extend the test for isContextivityDistributionFromEnv to
cover the accepted "yes" value and case-insensitive, whitespace-trimmed
variants, while preserving the existing assertions for "1", "true", "0", and an
unset environment. Ensure the tests verify normalization before comparison
without changing the parser implementation.
In `@apps/server/src/environment/ServerEnvironment.ts`:
- Line 137: Update the Effect.gen flow in ServerEnvironment to obtain the
distribution flag through an injected service, preferably ServerConfig or the
existing environment service, and pass that value to
isContextivityDistributionFromEnv instead of reading process.env directly.
Preserve the current contextivityDistribution behavior while keeping the
environment access testable and within the Effect boundary.
In `@apps/server/src/provider/acp/ContextivityAcpExtension.ts`:
- Around line 176-189: Update the record-envelope parsing logic around
parseAcpSubagentRecord to reject delta envelopes whose records exceed
MAX_DELTA_RECORDS, matching the existing snapshot overflow behavior instead of
silently truncating them. Preserve parsing for valid-sized deltas and update
ContextivityAcpExtension.test.ts to assert rejection of oversized delta input.
In `@apps/server/src/provider/acp/ContextivityAcpSubagentMapper.ts`:
- Around line 216-238: Simplify the guard in emitProgressIfPresent to return
when summary is absent, removing the redundant record.lastToolName condition.
Preserve the existing summary fallback chain and progress event construction.
- Around line 62-120: Make state updates copy-on-write for every mutable
TrackedChild: clone each existing child before modifying it in applyRecord,
including the emitCancelled path, and store the clone in state.children. Ensure
returned mapper state never shares mutated child objects with the input state
while preserving existing epoch and event behavior.
In `@apps/server/src/provider/Layers/AcpRegistryAdapter.ts`:
- Around line 309-445: Extract the duplicated ACP session state-machine logic
from AcpRegistryAdapter and GrokAdapter into a shared module under provider/acp,
including settlePromptInFlight, sendTurn, interruptTurn,
appendPromptResultToTurn, selectPermissionOptionId, and prompt-settlement
handling. Parameterize the shared implementation by PROVIDER, resume schema, and
model-selection helpers, then update both adapters to use it while preserving
their existing provider-specific behavior.
In `@contextivity/package.json`:
- Around line 10-14: Remove the redundant --experimental-strip-types option from
the test and cli scripts, the t3-ctx launcher, README command examples, and the
generated test command in the cli implementation, while preserving the existing
commands and behavior otherwise.
In `@contextivity/src/atomic.ts`:
- Around line 49-63: Update readLinkOrNull and readTextOrNull to return null
only when the filesystem error code is ENOENT; rethrow all other errors so
currentInstallId and the CLI do not treat permission, I/O, or loop failures as
missing files.
In `@contextivity/src/cli.ts`:
- Around line 441-476: Extract the duplicated commands object used by
stageCandidate into a shared stageCommands(token) helper near
activateVerifyCommands, preserving the existing extractArchive, preflight, and
conditional verifyAttestation behavior while retaining each call’s GH_TOKEN
composition through the helper’s token input. Replace both inline command blocks
with calls to this helper.
In `@contextivity/src/fleet.test.ts`:
- Around line 65-70: Document the intentional argument-boundary collapse in
sshFlattenedRemoteArgv with a one-line comment explaining that joining and
re-splitting models SSH’s remote-shell behavior and protects the base64
transport regression covered by Line 127.
In `@contextivity/src/hash.ts`:
- Around line 13-19: Update sha256File to use NodeStreamPromises.pipeline with
the file read stream and hash stream instead of stream.pipe, awaiting pipeline
completion before returning hash.digest("hex") so errors propagate and both
streams are cleaned up.
In `@contextivity/src/host-command.test.ts`:
- Around line 59-81: Update the test creating the temporary directory with
NodeFS.mkdtempSync to register cleanup via an after hook or t.after callback,
removing the directory and its marker after assertions complete while preserving
the existing test behavior.
- Around line 34-38: Update the test named “rejects truncated or non-canonical
encodings” to include a genuinely truncated value derived from
encodeHostCommandArg, while retaining the existing invalid and non-canonical
cases. Ensure the new assertion verifies decodeHostCommandArg rejects the
truncated encoding.
In `@contextivity/src/identity.ts`:
- Around line 83-108: The -ctx. validation in assertDualIdentity is unreachable
after the equality and nightly-format checks; move the
protocolVersion.includes("-ctx.") guard before the protocolVersion equality
check so suffixed protocol versions produce the specific error while preserving
all existing validation and return behavior.
In `@contextivity/src/inventory.ts`:
- Around line 29-35: Extend assertNoHardcodedSecrets to reject the additional
GitHub token prefixes gho_, ghs_, ghr_, and ghu_ alongside the existing ghp_ and
github_pat_ checks, preserving the current error behavior and label usage.
In `@contextivity/src/manifest.test.ts`:
- Around line 138-175: Register t.after cleanup for every temporary directory
created by the affected tests: remove contextivity/src/manifest.test.ts lines
138-175 directories dir and incomplete, contextivity/src/release.test.ts line 37
directory, and contextivity/src/fleet.test.ts lines 359-360 directories using
recursive, forced NodeFS.rmSync cleanup. Ensure each cleanup is registered
immediately after its corresponding mkdtempSync call.
In `@contextivity/src/manifest.ts`:
- Around line 148-159: Remove the `as ManifestArtifact` assertion from the
mapped result in `normalizeArtifacts` and preserve type safety by validating or

Let `normalizeArtifacts` perform the existing `isArtifactPlatform` runtime
validation and conversion rather than masking the incompatible `platform` type
with a cast.
In `@contextivity/src/pack-server.ts`:
- Around line 43-51: Update the archive creation flow around tar and the return
in the containing function to remove the stage-${platform} staging directory
from outDir after tar completes, including when archive creation fails, while
preserving the existing error propagation and archivePath return behavior.
In `@contextivity/src/pack.test.ts`:
- Line 44: Move the platformFromName assertion into a dedicated test focused on
platform detection, separate from the “stages dist, marker, and wrapper” test.
Keep the assertion unchanged and leave that staging test responsible only for
staging behavior.

once, validate that string with containsUpstreamPackageFallback before any
filesystem write or chmod, and only then pass the validated content to
atomicWriteFile.
In `@contextivity/src/policy.test.ts`:
- Line 78: Expand the assertNoPrivateSigningKey tests to cover each forbidden
key—COSIGN_KEY, CONTEXTIVITY_SIGNING_KEY, CONTEXTIVITY_T3_SIGNING_KEY, and
COSIGN_PRIVATE_KEY—and verify each populated value throws. Add pass-path
assertions for no forbidden keys and for a whitespace-only value, which must be
treated as unset.
In `@contextivity/src/provenance.ts`:
- Around line 1-24: Rename ProvenanceMode’s "optional" state to an
enforcement-accurate name such as "required-if-configured", and update
provenancePolicy plus all consumers including shouldVerifyAttestation and
stageCandidate to use the new value consistently. Preserve the existing behavior
that attestation remains enforced and fails when no verifier is configured.
- Around line 58-64: Update attestationVerifyArgs to always include the

Contextivity/t3code/.github/workflows/contextivity-candidate.yml, removing any
optional behavior so existing callers cannot leave workflow verification
unrestricted.
In `@contextivity/src/release.test.ts`:

The failure report is skipped when the CLI throws.
cli.ts only writes JSON to stdout on handled failures. On an unhandled error it writes the message to stderr and exits 1, leaving $RUNNER_TEMP/sync.json empty. JSON.parse then throws, reason=$(...) fails under set -eu, and the script exits before report-sync-failure runs. The fail-closed issue never gets filed for exactly the cases that most need it.

GitHub Actions macos-13 runner retirement date hosted runner labels
💡 Result:
The GitHub Actions macos-13 runner image was officially retired on December 4, 2025 [1][2]. Following this retirement, it is no longer supported for use in GitHub Actions workflows [3]. To address the removal of this image, GitHub introduced the macos-15-intel label as a replacement for users who require an x86_64 (Intel) environment on macOS [4]. Users who were previously using macos-13 are advised to migrate their workflows to macos-14, macos-15, or the macos-15-intel label depending on their architecture requirements [2][4].

💡 Result:
As of August 22, 2026, the status of GitHub Actions hosted runner labels for macOS is as follows: macOS 15: The macos-15-intel runner label is available and supported for x64 architecture [1][2]. This is designated as the final supported Intel-based image for GitHub Actions, with support scheduled until August 2027 [3][2]. macOS 26: The macos-26-intel runner label exists and is available for use [1][4]. It provides x64 architecture support [1]. macOS 14: These images are currently being phased out [5][6]. Deprecation began on July 6, 2026, and they will be fully unsupported by November 2, 2026 [5]. Users are encouraged to migrate workflows using macos-14, macos-14-large, or macos-14-xlarge to newer versions such as macos-latest (which now uses macOS 26), macos-15, or macos-26 [5][7]. Summary Table of Intel (x64) Support Runner Label | Status | Notes --- | --- | --- macos-15-intel | Supported | Last supported Intel image until August 2027 [3][2]. macos-26-intel | Available | Supported x64 architecture [1][4]. macos-14 | Deprecating | Unsupported after November 2, 2026 [5]. In general, macos-latest now refers to macOS 26 (Apple Silicon) [7]. Users requiring x86_64 environments must specifically use the designated Intel labels [4][2].

GitHub Actions matrix fail-fast unavailable runner label queued job behavior official documentation
💡 Result:
In GitHub Actions, the behavior of a matrix job when a runner label is unavailable or a job remains queued depends on whether the mismatch is considered an impossible configuration or a temporary resource shortage. If a job specifies a runner label (or label set) that does not exist or is never registered, GitHub immediately fails the job with an error indicating no runner matches the specified labels [1]. Because this is treated as an invalid configuration rather than a failure of a running job, the fail-fast setting does not typically apply to this specific "job start" error in the way it handles execution failures [1]. When runners are available but busy, jobs enter a "queued" or "pending" state [2]. If fail-fast is set to true (the default) and one job in the matrix fails during execution, GitHub will cancel all other in-progress and queued jobs within that same matrix [3][4]. This cancellation includes jobs that are currently waiting in the queue for an available runner [4]. If you need to ensure that jobs continue to run or at least attempt to queue despite a failure elsewhere in the matrix, you must set strategy.fail-fast: false [3][5]. With fail-fast disabled, a failure in one matrix leg will not trigger the cancellation of other legs, allowing them to proceed or remain in the queue until a runner becomes available [5][4]. Key distinctions: - Immediate Failure: If the runner label is invalid (e.g., misspelled), the job fails instantly before it can be queued [1]. - Queued/Pending: If the runner label is valid but no runners are currently idle, the job remains in a queued state [2]. - Fail-Fast Behavior: When fail-fast: true is active, a failure of any completed or in-progress matrix job will force the cancellation of all other jobs in that matrix, including those currently waiting in the queue [3][4]. Setting fail-fast: false prevents this behavior [5].

Replace macos-13 with a supported Intel runner label.
macos-13 is retired, so the darwin-x64 matrix leg fails before it runs. Use macos-15-intel or macos-26-intel. macos-14 is also scheduled for retirement on November 2, 2026.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The default harness leaks the real process.env into the test.
When options.env is undefined, the harness passes {}. ServerSelfUpdate.make then runs options.env ?? process.env, so env becomes the real process environment, not an empty one. Every test that does not set env therefore depends on the machine. If CONTEXTIVITY_T3_DISTRIBUTION is set in a developer shell or on a CI runner, those tests fail with the refusal reason instead of the expected result.
Pass an explicit empty object instead.

Unhandled stdin error can crash the process.
If the child exits or closes stdin before the write lands, child.stdin emits error (EPIPE). No error listener is attached to that stream, so Node throws an uncaught exception. The child.on("error", ...) handler on Line 64 does not cover stream errors. This is reachable for any short-lived command such as exit 1, which contextivity/src/updater.test.ts Line 295 exercises.

Add the failing-attestation case; it is the actual provenance gate.
The test covers the missing-verifier path and the success path. It does not cover a verifier that exits non-zero. That branch in stageCandidate (contextivity/src/updater.ts Lines 172-174) is the only thing that stops a staged artifact with an invalid attestation. It is currently untested. Also assert the args passed to verifyAttestation, so a change to attestationVerifyArgs cannot silently target the wrong repository.

The version directory lifecycle does not protect the directories that current and previous reference. Staging removes a version directory purely by manifest identity, and rollback repoints current without confirming the target directory still exists. Together these let the CLI leave current pointing at a path that is gone, with no recovery.

Activation silently widens permissions on the layout root.
NodeFS.chmodSync(input.layout.root, 0o755) runs on every activation. If an operator restricts the Contextivity home to 0o700, the next activation makes it world-readable and world-traversable. The root holds manifests and staged server trees. Remove the unconditional chmod, or apply it only when the directory is created.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
rollbackCurrent does not check that the rollback target exists.
The function reads both symlinks and swaps them. It never verifies that versions/<previous> is present on disk, unlike activateStaged, which checks on Line 219. If the previous version directory was pruned, rollback reports success and leaves current pointing at a missing path. Add the same existence check before the swap.
Also note that activateAndVerify calls this inside a catch on Line 274. If rollbackCurrent throws, it replaces the original restart or health error, and the operator loses the reason for the failure.
🛡️ Proposed guard
if (!previous) {
throw new Error("Nothing to roll back: previous is unset.");
}
+ if (!NodeFS.existsSync(versionDirFor(layout, previous))) {
+ throw new Error(`Cannot roll back to ${previous}: its version directory is missing.`);
+ }

In `@contextivity/src/updater.ts` around lines 231 - 246, Update rollbackCurrent
to verify that the previous version directory exists before calling
atomicSymlink, reusing the same existence-check behavior or helper used by
activateStaged; keep the swap and return behavior unchanged when the target
exists. Ensure a failed rollback preserves the original activateAndVerify error
when invoked from its catch path, rather than replacing it with the rollback
error.
