Bundled runtime

Before executing a CLI line below, replace its leading SSF with node "<plugin-root>/scripts/spec-superflow.mjs"; <plugin-root> is the absolute directory two levels above this file. Never run SSF literally or call an ssf from PATH.

Workflow routing

A new request follows this file without loading legacy instructions. For an existing change, inspect the recorded state and receipt/plan (available through SSF workflow show <change-dir> --json and SSF execution show <dir> --json when needed). Current paths are workflow_variant: direct with a valid workflow-selection receipt schema_version: 3, or workflow_variant: planned with an execution plan schema_version: 2. Older receipts (schema 1/2), legacy plans and other recorded variants use the matching section of SSF runtime asset read docs/legacy-workflow.md; follow that section for this change. A direct variant alone is insufficient: legacy Quick/Hotfix/Lightweight can also record it. The internal workflow: full value alone is not a legacy signal. Missing or corrupt state, receipt or a required plan is a recovery problem; preserve evidence rather than reinitialize or downgrade the change.

Core principle: Find root cause before attempting fixes. Symptom fixes are failure.

New direct/planned changes

Investigate in executing without a phase transition or a separate debug ledger: reproduce, trace the root cause, make one focused repair and verify. Keep useful failure evidence in the existing progress entry. Three failures for the same unresolved issue warrant a decision; unrelated findings do not accumulate a shared budget. No task book or subagent is required.

The Iron Law

No fixes without root cause investigation first. If you haven't completed Phase 1, you cannot propose fixes.
