history overwrote its years argument with the span it measured, so the block's parameters reported a span nobody asked for and the blockId moved with the data; the parameters now carry the argument as given and the heading keeps the span found. statements took any kind, so a specimen with a source named fell through to the classification gap sentence; the kinds it selects by are STATEMENT_KINDS in the store, which refuses any other, as gap now refuses a kind outside COVERAGE_WORDS in place of the MCP wrapper's hand check; the spec carries both enums, the CLI their choices, and the dead claims.KINDS and the dead ranges keys of the coverage map go. The planner prompt offered a diagnosis kind and a diagnoses gap that never existed.

Plan validation now enforces enum, minItems and maxItems, so a one-element years or a bogus trees or gap kind is a plan error rather than an unpack message from inside a tool, and tools.call checks the span's shape for the MCP surface, which bypasses validation; execute catches only ValueError, so a KeyError or TypeError is the bug it is. The CLI plan command reports an unreadable file or bad YAML with exit 2 instead of a traceback.

descendants sorted by a sixteen-rank tuple that lacked variety, Parvclass, Subkingdom and every informal rank, so those rows sorted below species. phylohist/ranks.py holds the schema's rank enum in its order (a test keeps them equal), the species and genus groups, and the fold every comparison reads a rank through; it replaces the nine spellings of those tuples across both sides, the loader's numeric rank table (the genus-group order check gives the same verdict for every pair) and twenty-one hand-written lower-casings. Nothing about the rank semantics is decided here. Closure.name and rank delegate to the store, so the JSON schemes name a designated record as the words do, and the owner-path helper moves to Closure for the nine sites that spelled it inline.

No rendered string or row order that the tests or the eval questions pin changes; the derived files are untouched.
