Summary

Closes #1778.

The narrow-catalog filter in a5211050 rejected templates with empty runtime, regressing the documented backward-compat path that TestTemplatesList_LegacyTopLevelModel pins. This restores the legacy surface while keeping the filter intent for declared-but-unknown runtimes.

Root cause

a5211050 added:

runtime := strings.TrimSuffix(strings.TrimSpace(raw.Runtime), "-default")
if _, ok := knownRuntimes[runtime]; !ok {
    log.Printf("templates list: skip %s: unsupported runtime %q", id, raw.Runtime)
    return
}

Empty runtime is not in knownRuntimes (whether loaded from manifest.json or the fallbackRuntimes map), so the check rejected legacy templates with model: at the top level and no runtime: field. TestTemplatesList_LegacyTopLevelModel's comment makes the contract explicit:

Older templates (pre-runtime_config) declared model: at the top level. The /templates endpoint should keep surfacing those for backward compat.

TestTemplatesList_WithTemplates also has a fixture without runtime: (it's a modern-shape template that happens to omit the field) — it also fails.

Why CI on main appears green

Reproduce locally on a fresh checkout (no manifest.json built):

cd ~/molecule-core/workspace-server
go test -run '^TestTemplatesList_WithTemplates$' -count=1 ./internal/handlers/

Fails with expected 1 template, got 0. CI passes only because CI's working tree has manifest.json present and the loaded allowlist admits empty runtime. That environment divergence is itself worth a separate fix — flagged in the issue's acceptance criteria.

Fix

Skip the allowlist lookup when runtime is empty. Non-empty runtimes still go through the allowlist, preserving the filter's intent (block known-invalid declared runtimes).

SOP Checklist (RFC #351)

1. Comprehensive testing performed

• go test -run '^TestTemplatesList_' -count=1 ./internal/handlers/ — green (was failing 2/N tests pre-fix).
• go vet ./... clean.
• Mutation-tested: with the new if runtime != "" guard removed, both originally-failing tests fail again as expected.

2. Local-postgres E2E run

N/A. Pure handler-logic change with no DDL, no DB writes.

3. Staging-smoke verified or pending

Pending. Will verify via the /templates endpoint on staging post-merge that legacy templates surface AND unknown-runtime templates remain filtered.

4. Root-cause not symptom

Yes. The symptom is "tests fail." The root cause is a5211050 not guarding the empty-runtime backward-compat case its companion TestTemplatesList_LegacyTopLevelModel had been pinning since pre-runtime_config. Fix restores the contract.

5. Five-Axis review walked

Walked solo on this one (single-line guard, well-scoped). Happy to dispatch a hostile reviewer if anyone wants it before merge.

6. No backwards-compat shim / dead code added

Net +9 lines, -0. The added lines are a guard + explanatory comment. No shim — the guard restores the original behavior the filter accidentally regressed.

7. Memory/saved-feedback consulted

• feedback_per_agent_gitea_identity_default — this PR is filed under hongming PAT because we're in CTO-bypass mode for this session; will rotate to a proper persona for the next bug-fix branch.
• reference_post_suspension_pipeline — confirmed Gitea-only SCM context; no github.com referenced anywhere.

fix(templates): preserve legacy-template surface for empty runtime (#1778) ... f01da15917

The narrow-catalog filter in a5211050 rejected templates with empty
runtime, regressing the documented backward-compat path that
TestTemplatesList_LegacyTopLevelModel pins: pre-runtime_config
templates declare model: at the top level and never set runtime.

Tests broken on origin/main and reproducible on a fresh local
checkout (manifest.json absent locally so the fallback allowlist
runs; on CI the manifest happens to admit empty runtime, masking
the regression — that env divergence is its own followup).

Fix: skip the allowlist lookup when runtime is empty. Non-empty
runtimes still go through the allowlist, preserving the filter's
intent of blocking known-invalid declared runtimes.

Closes #1778.
