  "description": "Measures the complexity of the code a phase touched and, when a function crosses a configured threshold or jumps past its recorded anchor, surfaces a scoped refactor proposal at .planning/phases/<N>/<NN>-REFACTOR.md. Advisory by default — it never edits code and never blocks. Opt-in strict mode blocks /gsd-ship while a proposal is untriaged; a declined proposal is recorded in the broken-windows ledger when that capability is present. Operationalizes 'refactor early, refactor often' as continuous pressure instead of a thing you have to remember (issue #1953).",

Semantics match ESLint's `complexity: {max: N}` — the trigger is STRICTLY GREATER, so a score of exactly N does not trigger. Default 15 follows SonarSource's default; ESLint's own default is 20 and radon's rank C begins at 11. Raise it if proposals feel like noise."

Measured against the function's anchor — the score recorded the last time the function was consciously dispositioned — so it accumulates across phases and catches slow creep the absolute threshold would miss. Strictly greater, as with the threshold."

      "description": "Record an untriaged refactor proposal as an open `deviation` entry in the broken-windows ledger, so it becomes a tracked task that must be resolved before ship. Off by default and deliberately so: a blocking complexity number is a metric an executor can satisfy by splitting one coherent function into two incoherent ones, so the entry clears on the proposal being DISPOSITIONED (gsd-tools refactor accept|decline), never on the score improving. Ship blocking is the broken-windows capability's existing ship:pre gate — enable it with workflow.windows_enforce. With broken-windows absent, strict mode still records the proposal locally and says so; it cannot block on its own. Advisory mode (the default) surfaces the same proposal and tracks nothing."
