Part of #1801.

This PR removes the laptop CPEX build from the release, install, update and
doctor paths. It also updates the documentation, the Makefile and the stale
comments. The base is c50de9be4, the tip of main after #1866 merged, so
docs/praxis-policy.md exists.

What changed

• Release (003a4af9c): .github/workflows/release-binaries.yaml does not
  build or publish cortex-cpex_* tarballs. The build-cpex job is deleted.
  publish no longer needs it and no longer gates on it.
• Update (d234c8f06, 8ede6d2e1, 472400a35): agentop update moves a
  cpex install to the default build. releaseTarballs no longer takes a cpex
  argument. The update prints a notice that names --praxis. The notice also
  applies when the newest tag replaced a cpex cortex. The automatic update
  writes a short line to update.json, and agentop shows it on the title bar:
  that job has no terminal, and its stdout only reaches ~/.cortex/update.log.
• Install (9fe1182c5): install.sh --cpex exits with an error that points
  to praxis mode. install.sh no longer stages a cpex tarball.
• Doctor (9fe1182c5): the doctor fix one-liner no longer passes --cpex.
• Smoke test: scripts/release_smoke_test_linux.sh no longer switches to the
  cpex build and back. scripts/install_test.sh loses the cpex scenes and the
  cpex | nocpex mode of make_release.
• Docs (bc5ad82bd, 001a79dec, fa6a09958, 6f6035b7b): the cpex pages,
  cmd/README.md, README.md, .github/CLAUDE.md and docs/proxy-contract.md
  state the removal. The make cortex-cpex target is gone. The release notes
  now tell a cpex user how to move: an old agentop update asks for the removed
  tarball, so it cannot do the move itself.
• Stats (6f6035b7b): the install-stats page and its collector said a
  tag-push smoke run counts up to 5 installs per job. That number came from the
  cpex steps. It is 2 now: the upgrade and the re-install.

installedIsCpex stays. It is how the update detects an old install.

Size

• Counted lines: 683 added + removed (limit 2000).
• Exempt lines: 490, all in
  docs/superpowers/plans/2026-11-13-ppe-remove-laptop-cpex-1801.md (the plan
  document).

How it was tested

Run in the worktree on 6f6035b7b:

• scripts/dev/go-test-shards.sh -short cmd/agentop: 1087 tests in 8 shards,
  all pass.
• GOWORK=off go test in every other cmd/agentop package: all pass.
• GOWORK=off go vet ./... in cmd/agentop; gofmt -l on every changed Go
  file: no output.
• bash scripts/install_test.sh: 255 passed, 0 failed.
• shellcheck --severity=error on scripts/collect-install-stats.sh.
• pre-commit run on every changed file.
• release-binaries.yaml loads with PyYAML.

For a human after review

These steps are not tasks. A person must do them, or they change state outside
the repository.

1. Start and end the deprecation window (Hai). This blocks the merge.

Steps:

• Wait for a release that ships docs: Document praxis policy and deprecate the laptop cpex build #1866, so users see the cpex deprecation line.
• After that release, write one comment on PPE 5/5: Remove the laptop CPEX build after the deprecation window #1801: "the deprecation window has
  ended". PPE 4/5: Document PPE in praxis mode and deprecate the laptop CPEX build #1800 requires at least one release in which users saw the
  deprecation.

Needs: nothing in this branch. It needs #1866 (merged) and one release.

2. Check the release notes after this PR merges. This PR adds a permanent
line to the generated notes: a cpex install must run the one-liner once,
because an older agentop update cannot fetch the removed tarball. Check that
the line appears in the next release's notes.

3. Tell the CPEX contributor. #1800 already asks for a message to Frederico
Araujo (araujof) about the deprecation. After this removal PR merges, send one
message that the laptop build is gone. Do not send it before the merge.

Walkthrough

The changes remove laptop CPEX release and installation paths. Updates from an installed CPEX build now use the default Cortex build. Kubernetes CPEX image support remains.

Changes: Laptop CPEX removal

Layer / File(s)	Summary
Remove CPEX release jobs and smoke coverage .github/workflows/release-binaries.yaml, .github/workflows/release-smoke-linux.yaml, scripts/release_smoke_test_linux.sh, docs/superpowers/plans/2026-11-13-ppe-remove-laptop-cpex-1801.md	The release workflow no longer builds or requires CPEX tarballs. Linux release smoke coverage no longer switches between CPEX and default builds.
Reject laptop CPEX installs scripts/install.sh, scripts/install_test.sh, docs/superpowers/plans/2026-11-13-ppe-remove-laptop-cpex-1801.md	The installer rejects --cpex with guidance to --praxis, selects the standard Cortex archive, and reports when it replaces an installed CPEX build. Tests cover the rejection and replacement notice.
Update CPEX installs to the default build cmd/agentop/cmd_doctor_checks.go, cmd/agentop/cmd_doctor_checks_test.go, cmd/agentop/cmd_update.go, cmd/agentop/cmd_update_auto.go, cmd/agentop/cmd_update_auto_test.go, cmd/agentop/cmd_update_test.go, cmd/agentop/update_stage.go, cmd/agentop/update_stage_test.go, docs/superpowers/plans/2026-11-13-ppe-remove-laptop-cpex-1801.md	agentop update no longer selects CPEX tarballs or treats a CPEX install as current. It prints a replacement notice and stages the standard Cortex release. Doctor repair guidance uses the standard installer command.
Remove laptop build instructions and retain image support Makefile, README.md, cmd/README.md, core/plugins/cpex/README.md, docs/cpex-plugin.md, docs/laptop-service.md, docs/plugin-catalog.md, docs/proxy-contract.md, scripts/profile-tags/profiles.go, docs/superpowers/plans/2026-11-13-ppe-remove-laptop-cpex-1801.md	The laptop Makefile target and related documentation are removed or updated. The documentation identifies authbridge-cpex and Kubernetes use as retained, and updates the fullcpex profile description.

Merge Risk: Moderate · up to fa6a0

This change removes the laptop CPEX build, but the repository's own plan says that should wait for a deprecation release and written approval, and neither is evidenced. Confirm the gate before merging. The update notice also claims the default build was installed before the install has succeeded, so it should be reworded as pending.

Explanation

The title "feat: Remove the laptop cpex build" matches the main change in the changeset. The PR removes the laptop CPEX release tarball, the install.sh --cpex install path, the agentop update and doctor handling of cpex builds, the Makefile cortex-cpex target, and related docs and smoke tests. The Kubernetes authbridge-cpex image and CPEX plugin code stay unchanged, which the title does not need to state.

Reword the CPEX notice as an attempt.

The notice prints before staging checks and setup run. Its text says that the default cortex was installed, but a checksum, provenance, or setup failure can leave the CPEX build in place. Describe the replacement as pending:

Suggested fix

-const cpexUpdateNotice = "the laptop cpex build is removed: installed the default cortex; use praxis mode with praxis.policy for laptop policy (docs/praxis-policy.md)"
+const cpexUpdateNotice = "the laptop cpex build will be replaced by the default cortex; use praxis mode with praxis.policy for laptop policy (docs/praxis-policy.md)"

Hold the laptop CPEX removal until the deprecation gate is met.

The plan's header marks this work as BLOCKED. Its Blocked section requires a release that ships the deprecation, and then Hai's written approval on #1801. The reviewed head already changes the release workflow, install.sh, the Makefile, and the agentop update and doctor paths to remove the laptop CPEX build. Merging this change before the gate is met removes laptop CPEX installs and archives at the next release.

Remove the implementation changes from this PR, or hold the merge, until #1801 has Hai's approval and the deprecation release has shipped. Keep the plan document in this PR as the blocked record.

Summary

The removal itself is clean: the release job, releaseTarballs, install.sh, doctor, the smoke test and the docs all line up. No leftover reference to the removed tarball or make cortex-cpex breaks a build, script or workflow. I am requesting changes for one reason. The migration this PR promises ("agentop update moves a cpex install to the default build", and the release-note line "run the install one-liner once") does not work for the user it targets: anyone whose ~/.cortex/config.yaml actually uses the cpex plugin.

Must-fix: the move to the default build fails, and rolls back, when the config names cpex. The default cortex does not register cpex, and plugins.BuildWithDeps stops startup on an unknown plugin name. I checked this on the head commit. I built cmd/cortex with the full profile, added a cpex entry under pipeline.outbound.plugins in the built-in --local config, and ran it. It exits 1:

level=WARN  msg="the laptop cpex build is deprecated; ..."
level=ERROR msg="initial pipeline build: outbound: unknown plugin \"cpex\" (registered: [a2a-parser ibac inference-parser ... tool-prune])"

So for anyone who installed the cpex build to use it (the plugin is a no-op until the config names it), every path this PR adds ends in setup's health check failing and a rollback:

• agentop update prints cpexUpdateNotice ("installed the default cortex"), and then the service never answers /healthz. Setup rolls back to the cpex binary.
• agentop update --auto records ResultFailed. The cpex binary stays, so the next check every check_every downloads and fails again, until the user edits the config.
• The release-note and docs/laptop-service.md repair ("run the install one-liner once") goes through the same agentop setup hand-off and fails the same way.

The tests do not catch this. Every cpex row uses a fake cortex script and a config with no cpex entry.

Fixing this needs one of two things. (a) Handle the config: setup or update removes, or turns off with on_error: off, a cpex outbound entry when it moves to the default build, and says so. Or it refuses before it downloads, with a message that names the entry to remove and links docs/praxis-policy.md#move-from-the-cpex-plugin. (b) At the least, make the notice, the release note and laptop-service.md tell the user to remove the cpex entry from pipeline.outbound.plugins first. Then the stated repair works. Option (a) is better because the auto-updater is otherwise stuck in a loop. A test row with a real cpex entry in the config would cover it.

Smaller items (inline): the update notice prints "installed the default cortex" before the install runs. The --cpex hint in install.sh and the doctor fix line have the same missing-config gap.

Nits (outside the diff): core/plugins/cpex/plugin.go:27-28 still says make cortex-cpex links the package, and .github/workflows/ci.yaml:189 still calls fullcpex "the laptop build". profiles.go now calls fullcpex "the authbridge-cpex image", but that image uses the cpex profile (build.yaml), not fullcpex. After this PR, nothing ships fullcpex. Only the CI job builds it.

[clawgenti]

must-fix: this is where the migration starts, but it only works when ~/.cortex/config.yaml does not name cpex. The default cortex has no cpex plugin, and BuildWithDeps stops startup on unknown plugin "cpex". I checked this with a full-profile build on this commit. So for a user who actually runs the cpex plugin, setup's health check fails and rolls back to the cpex binary, and this notice has already told them "installed the default cortex".

Please handle the config here or in setup. Either drop or turn off the cpex outbound entry and say so, or refuse before the download with a message that names the entry to remove and links docs/praxis-policy.md#move-from-the-cpex-plugin.

Also (suggestion): the line is printed before the install runs, so "installed" is wrong whenever the install then fails. "installing the default cortex" would be accurate.

[clawgenti]

must-fix (same root cause): with a cpex entry in the config, this branch downloads and stages the default build, setup fails its health check and rolls back, and the status is ResultFailed. The cpex binary is still there, so wasCpex is true on the next check too, and the updater repeats the download and the failed restart every check_every until someone edits the config. The cpex current test row passes only because the fake installer never starts a real cortex against a config.

[clawgenti]

must-fix (docs part of the same issue): "run the install one-liner once" hands off to the same agentop setup, so it fails the same way when the config names cpex. Please add the step that makes it work, for example: "first remove the cpex entry from pipeline.outbound.plugins in ~/.cortex/config.yaml (see docs/praxis-policy.md, Move from the CPEX plugin)". The same applies to docs/laptop-service.md and the install.sh replacement notice.

[clawgenti]

must-fix (docs): the move to the default cortex works only when the config does not name cpex. With a cpex entry, the default build exits at startup (unknown plugin "cpex") and setup rolls back. Please say so here, and link the migration steps in praxis-policy.md#move-from-the-cpex-plugin. The repair paragraph below needs the same step.

[clawgenti]

suggestion: this is where a cpex user who runs the one-liner from the release notes ends up. It would be a cheap place to check ~/.cortex/config.yaml for a - name: cpex outbound entry, and either warn or die with the fix before the download, staging and setup run. Without that check, the user gets a failed health check and a rollback, with only a log tail to explain why.
