/**
* Broken-windows ledger — behavioral + property tests.
*
* Module: gsd-core/bin/lib/broken-windows.cjs (compiled from src/broken-windows.cts)
* CLI: gsd-tools windows <status|append|waive|fixed>
*
* Issue: #1950 — enforced cross-phase defect register gating /gsd-ship.
*
* Coverage map (acceptance criteria from #1950):
* - Executor writes stubs to ledger → append (CLI + pure)
* - /gsd-ship fails while any entry is open → openCount + cmdWindowsStatus
* - Waive requires non-empty reason → markWaived / cmdWindowsWaive
* - Marking fixed removes from blocking set → markFixed / cmdWindowsMarkFixed
* - Open-window count in progress surface → cmdWindowsStatus emits open_count
* - Tests cover all four + clean-on-empty → empty ledger + full lifecycle
*
* Hermetic: each CLI test uses its own tmpdir via createTempDir and cleans up
* via t.after() (CONTRIBUTING.md pattern 2). No shared state between tests.

// #3780: parallel writers must not silently lose ledger mutations
//
// cmdWindowsAppend/Waive/MarkFixed each ran an unlocked read-compute-write
// cycle ending in an atomic rename: two parallel invocations read the same
// snapshot, computed the same nextId, and the second rename won — the first
// mutation was silently lost while its invocation still reported ok:true
// (a false-green /gsd-ship gate, since the ship decision reads open_count).
// The fix serializes the mutating commands on a `.planning/.WINDOWS.lock`
// ledger lock backed by the shared capability-lock primitive (the
// capability-consent precedent: waitForFresh + raised budget, typed throw
// when the lock cannot be acquired). Readers stay lock-free.
