fix(plugins): log silently ignored execAsRoot errors during uninstall

Plugin uninstall had two sites where execAsRoot errors were discarded: - Skill directory removal (plugins_install.go:125) — orphaned skill dirs if rm -rf failed silently - CLAUDE.md marker stripping (plugins_install_pipeline.go:326) — stale plugin content left in CLAUDE.md if awk script failed Both now log the error without failing the overall uninstall (best-effort cleanup), giving operators visibility into incomplete uninstalls.

-    # This job deliberately has no `needs:`. Gitea 1.22/act_runner can mark a
-    # job-level `if: always()` + `needs:` sentinel as skipped before upstream
-    # jobs settle, leaving branch protection with a permanent pending
-    # `CI / all-required` context. Instead, this independent sentinel polls the
-    # required commit-status contexts for this SHA and fails if any fail, skip,
-    # or never emit. It runs the same path detector as `changes` and only waits
-    # for path-relevant jobs; Gitea can otherwise leave needs/output-skipped
-    # jobs permanently pending with "Blocked by required conditions". It runs on
-    # the dedicated `ci-meta` lane so the poller does not occupy the same
-    # general runner pool as the jobs it is waiting for.
+    # ── 2026-06-01 CI-scheduler-overload fix (fix/ci-scheduler-fanout) ──
+    # PREVIOUS shape: a poll-gate that ran detect-changes then LOOPED on
+    # `GET /commits/{sha}/statuses` every 15s for up to 40 min, occupying a
+    # `ci-meta` executor slot the entire time it waited for upstream jobs.
+    # With only 2 ci-meta runners, that poll-loop squatted half the lane on
+    # every PR — a confirmed throughput sink in the live RCA (two concurrent
+    # `JOB-all-required` containers observed pinning the lane). The polling
+    # design existed only to dodge the Gitea `needs:` + `if: always()` bug,
+    # where an always()-guarded sentinel could be marked skipped before
+    # upstream jobs settled (leaving BP pending forever).
    #
-    # canvas-deploy-reminder is intentionally NOT included in all-required.needs.
-    # It is an informational main-push reminder, not a PR quality gate. Keeping
-    # it in this dependency list lets a skipped reminder skip the required
-    # sentinel before the `always()` guard can emit a branch-protection status.
+    # NEW shape: a plain `needs:` aggregator with NO polling loop. This is
+    # safe here — and was NOT safe at the time the poller was written —
+    # because every aggregated CI job now gates its real work PER-STEP
+    # (`if: needs.changes.outputs.* != 'true'`) rather than at the JOB level.
+    # A per-step-gated job always reaches a terminal SUCCESS (it no-ops its
+    # expensive steps but the job itself still completes), so it is never
+    # `skipped`. Plain `needs:` (WITHOUT `if: always()`) works correctly on
+    # Gitea 1.22.6 / act_runner v0.6.1 — only `needs:` + `if: always()` is
+    # broken (feedback_gitea_needs_works_only_ifalways_broken). We therefore
+    # use plain `needs:` + an explicit per-need result check (NOT
+    # `if: always()`); if any need fails/errors, Gitea never starts this job
+    # and BP sees `CI / all-required` go red via the failed dependency
+    # propagation — exactly the gate we want, with zero runner-squat.
    #
+    # The `needs:` list MUST stay in lockstep with ci-required-drift.py's
+    # F1 check (`ci_job_names()` = every job MINUS the sentinel MINUS jobs
+    # whose `if:` gates on github.event_name/github.ref). canvas-deploy-
+    # reminder is event-gated (`if: github.ref == refs/heads/{main,staging}`)
+    # so it is intentionally EXCLUDED — it skips on PRs and a `needs:` on a
+    # skipped job would never let the sentinel run. If a new always-running
+    # CI job is added, add it here too or ci-required-drift F1 will flag it.
+    #
+    # Stays on the dedicated `ci-meta` lane (no docker work, so the
+    # docker-host-pin lint does not apply), but now the job is sub-second:
+    # it only inspects already-settled `needs.*.result` values, so it frees

-# the goal is "no tenant workspace ever receives an operator-scope repo
-# token," not just "no _quoted_ literal `GITEA_TOKEN`." A future writer
-# could route the value via a variable, a struct field, or a config key
-# and slip past the existing literal scan; this lint catches those
-# routing patterns at PR review time.
-#
-# Scope
-#   Scans the WHOLE repo's Go sources (not just workspace-server/) for
-#   co-occurrences of:
-#     - a repo-host token NAME (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN /
-#       GITEA_PAT / GITHUB_PAT) used as os.Getenv argument or string
-#       literal
-#     - within a file that ALSO references a tenant-writer surface
-#       (`tenant`, `workspace_secrets`, `global_secrets`, `seedAllowList`,
-#       `/settings/secrets`, `userData`, `provisionPayload`,
-#       `envVars[`, `containerEnv`).
-#
-#   Co-occurrence (not single-line) is the false-positive control: a
-#   file that just LOGS the variable name (e.g. "missing GITEA_TOKEN")
-#   without touching any tenant surface won't fire.
-#
-# Drift contract with lint-forbidden-env-keys.yml
-#   Both lints share the same FORBIDDEN_KEYS list (a subset — only the
-#   repo-host tokens, since this lint's threat model is "tenant gets
-#   write access to operator's git host"). If RFC#523's deny set grows,
-#   update BOTH this file AND lint-forbidden-env-keys.yml AND the Go
-#   source-of-truth in
-#   workspace-server/internal/handlers/workspace_provision_forbidden_env.go.
-#
-# Open-source-template-friendly
-#   The patterns scanned are generic (no MOLECULE_-prefix literals).
-#   A fork can copy this workflow as-is and adjust FORBIDDEN_KEYS.
-#
-# Path-filter discipline
-#   No `paths:` filter — required-status workflows must run on every PR
-#   per `feedback_path_filtered_workflow_cant_be_required`. Scan is
-#   sub-second.

+# copy. RED if they differ — meaning the canonical moved and core's copy must be
+# re-synced (copy verbatim + `go generate ./...` + bump
+# canonicalProvidersYAMLSHA256 in sync_canonical_test.go).
+#
+# Pairs with:
+#   * sync_canonical_test.go — hermetic sha pin (catches a hand-edit of core's
+#     copy even with no network); runs in the normal `go test ./...`.

+# P2-A, CTO 2026-05-27 "Distribution = SDK via codegen + verify-CI").
+#
+# The canonical schema SSOT is molecule-controlplane
+# internal/providers/providers.yaml. molecule-core carries a SYNCED COPY at
+# workspace-server/internal/providers/providers.yaml (kept in sync by the
+# companion sync-providers-yaml.yml gate), and cmd/gen-providers emits the
+# checked-in Go projection workspace-server/internal/providers/gen/registry_gen.go.
+#
+# This workflow regenerates the artifact into the working tree and fails RED if
+# it differs from what is committed — catching BOTH:
+#   * a providers.yaml (synced-copy) change that wasn't followed by `go generate ./...`, and
+#   * a hand-edit of the generated artifact (it carries a DO NOT EDIT header).
+#
+# It is the molecule-core mirror of molecule-controlplane's verify-providers-gen
+# workflow. Together with sync-providers-yaml (canonical↔synced-copy drift) it
+# closes the codegen-checked-into-each-repo + verify-CI loop the RFC mandates.
+#
+# ENFORCEMENT GATING (deliberate, per dev-SOP "implementation gating"):
+# this is a STANDALONE workflow, NOT a job inside ci.yml, and is NOT yet in any
+# branch-protection status_check_contexts. Rationale (identical to the CP P0
+# rollout):
+#   * It runs + reports RED on every PR/push immediately (visible signal).
+#   * It is intentionally absent from ci.yml's job set so the ci-required-drift
+#     sentinel (jobs ↔ branch-protection ↔ audit-env) does NOT fire on it, and
+#     from branch protection (turning it into a hard merge gate has blast radius
+#     — operator GO required, same pattern as sop-tier-check / verify-providers-gen
+#     on controlplane). Promote it into branch protection in a follow-up once

-// Regression tests for ConfigTab Provider override (Option B PR-5).
+// internal#718 P4 closure — ConfigTab.provider.test.tsx is retired.
 //
-// What this pins: a free-text Provider combobox in the Runtime section
-// that lets the operator override the model→provider derivation hermes-
-// agent does internally. Without this UI, a fresh signup whose Hermes
-// workspace defaults to a model with no clean vendor prefix (e.g.
-// `nousresearch/hermes-4-70b`) hits the runtime's own preflight error:
-//   "No LLM provider configured. Run `hermes model` to select a
-//    provider, or run `hermes setup` for first-time configuration."
-// — even though tasks #195-198 wired the entire downstream pipe so a
-// non-empty provider WOULD flow through canvas → workspace-server →
-// CP user-data → workspace config.yaml → hermes adapter.
+// This 574-line suite exercised the canvas-side LLM provider override
+// flow: load the existing override from GET /workspaces/:id/provider,
+// edit the dropdown, Save → PUT /workspaces/:id/provider, and the
+// provider→billing_mode linkage on Save. All three server endpoints
+// behind those flows are retired in internal#718 P4 closure:
 //
-// Hongming Wang hit this on hongming.moleculesai.app at signup
-// 2026-05-01T17:35Z. Backend PRs were green, the gap was the missing
-// UI to set the value.
+//   - workspace-server SetProvider / GetProvider (PUT/GET
+//     /workspaces/:id/provider) → both return 410 Gone with a
+//     PROVIDER_ENDPOINT_RETIRED structured body.
+//   - workspace-server setProviderSecret (the writer into
+//     workspace_secrets.LLM_PROVIDER) — removed; row never written.
+//   - The LLM_PROVIDER workspace_secret itself — migrated away in
+//     20260528000000_drop_llm_provider_workspace_secret.up.sql.
 //
-// Each test pins one invariant. If any fails, the bug is back.
+// ConfigTab still renders the provider dropdown for display (the user
+// can preview the derived provider locally), but Save no longer
+// round-trips the value. The replacement contract is that the provider
+// is DERIVED at every decision point from (runtime, model) via the
+// registry — see internal/providers/derive_provider.go.
+//
+// The original suite's coverage is replaced by:
+//
+//   - workspace-server: TestPutProvider_410Gone +
+//     TestGetProvider_410Gone + TestProviderEndpointGone_BodyShape in
+//     internal/handlers/llm_provider_removal_p4_test.go.
+//   - workspace-server: TestWorkspaceCreate_FirstDeploy_OnlyPersistsMODEL
+//     in internal/handlers/workspace_provision_shared_test.go.
+//   - registry: TestDeriveProvider_RealManifest in
+//     internal/providers/derive_provider_test.go.
+//
+// Restore from git history if any aspect of the legacy LLM_PROVIDER
+// flow needs to be revisited (it should not — the retirement is
+// permanent).
