Symmetric with the existing CPProvisionerAPI interface. Closes the asymmetry where the SaaS provisioner field was an interface (mockable in tests) but the Docker provisioner field was a concrete pointer (not). ## Changes - New ``provisioner.LocalProvisionerAPI`` interface — the 7 methods WorkspaceHandler / TeamHandler call on h.provisioner today: Start, Stop, IsRunning, ExecRead, RemoveVolume, VolumeHasFile, WriteAuthTokenToVolume. Compile-time assertion confirms *Provisioner satisfies it. Mirror of cp_provisioner.go's CPProvisionerAPI block. - ``WorkspaceHandler.provisioner`` and ``TeamHandler.provisioner`` re-typed from ``*provisioner.Provisioner`` to ``provisioner.LocalProvisionerAPI``. Constructor parameter type is unchanged — the assignment widens to the interface, so the 200+ callers of ``NewWorkspaceHandler`` / ``NewTeamHandler`` are unaffected. - Constructors gain a ``if p != nil`` guard before assigning to the interface field. Without this, ``NewWorkspaceHandler(..., nil, ...)`` (the test fixture pattern across 200+ tests) yields a typed-nil interface value where ``h.provisioner != nil`` evaluates *true*, and the SaaS-vs-Docker fork incorrectly routes nil-fixture tests into the Docker code path. Documented inline with reference to the Go FAQ. - Hardened the 5 Provisioner methods that lacked nil-receiver guards (Start, ExecRead, WriteAuthTokenToVolume, RemoveVolume, VolumeHasFile) — return ErrNoBackend on nil receiver instead of panicking on p.cli dereference. Symmetric with Stop/IsRunning (already hardened in #1813). Defensive cleanup so a future caller that bypasses the constructor's nil-elision still degrades cleanly. - Extended TestZeroValuedBackends_NoPanic with 5 new sub-tests covering the newly-hardened nil-receiver paths. Defense-in-depth: a future refactor that drops one of the nil-checks fails red here before reaching production. ## Why now - Provisioner orchestration has been touched in #2366 / #2368 — the interface symmetry is the natural follow-up captured in #2369. - Future work (CP fleet redeploy endpoint, multi-backend provisioners) wants this in place. Memory note ``project_provisioner_abstraction.md`` calls out pluggable backends as a north-star. - Memory note ``feedback_long_term_robust_automated.md`` — compile-time gates + ErrNoBackend symmetry > runtime panics. ## Verification - ``go build ./...`` clean. - ``go test ./...`` clean — 1300+ tests pass, including the previously-flaky Create-with-nil-provisioner paths that now exercise the constructor's nil-elision correctly. - ``go test ./internal/provisioner/ -run TestZeroValuedBackends_NoPanic -v`` — all 11 nil-receiver subtests green (was 6, +5 for the newly-hardened methods).
