coherence-checklisted

# Coherence checks Two tiers. Deterministic rules are pure functions over the graph and run instantly. Judgment checks need a reader, which is you, and their answers are cached by content hash so an unchanged pair is never judged twice. ## Tier 1: deterministic ``` coherence check # everything, human-readable coherence check --json # machine-readable coherence check --severity warn # this severity and worse coherence check --no-judgment # skip cached verdicts ``` (Commands assume `coherence` on PATH; a repo may vendor it at `bin/coherence` instead. Use whichever exists.) Exit code 1 means at least one `block`-severity finding. The thirteen rules: | check | fires when | |---|---| | `dead-link` | a `parent:` or `serves:` points at an id that doesn't exist | | `orphan` | non-root artifact with no parent, so nothing connects it to the mission | | `illegal-parent` | the level chain is broken (a story hanging off a bet) | | `duplicate-id` | two files claim the same id | | `duplicate-singleton` | more than one live mission | | `stale-premise` | live work whose ancestor is `dropped` or `done` | | `lifecycle-contradiction` | done artifact with live children or unticked criteria | | `decomposition-gap` | active bet/goal/project with no children, a sentence rather than a plan | | `coverage-gap` | a user or problem nothing serves | | `unrealized-commitment` | done story whose `code:` globs match no files | | `priority-inversion` | child ranked mor
