The coding-loop description contract test repeated per-tool lookup, lowercasing and assertion loops. Replace those loops with named tables of tools, required phrases and forbidden phrases, sharing assertion messages that identify the tool/schema field, phrase and actual description. Keep registered tools and exact-manifest specialists in separate tables backed by their original inventories.

Preserve all 274 phrase checks (257 required, 17 forbidden), including shared Cargo validation expectations. Move the existing Git diff paging budget/cursor checks and persistent-shell result/resource schema checks into two focused tests. Production descriptions and all following tests remain unchanged. Only registry_specs.rs changes, with a net reduction of 66 lines.

Validation:

• cargo test --locked -p webcodex-tool-contracts --lib tests::registry_specs -- --quiet — 10 passed.
• cargo test --locked -p webcodex-tool-contracts --lib --all-features tests::registry_specs -- --quiet — 10 passed.
• Before the refactor, the same focused module passed 8 tests in each configuration; the increase comes from splitting out the two existing schema checks.
• A one-off comparison verified exact multisets of inventory/tool/field/polarity/phrase for all 274 checks, retention of the 4 structural schema assertions, and byte-identical following tests.
• Temporary mutations of the test's in-memory specs verified that removing never replay effects from work_on_project and inserting a forbidden phrase into read_files both fail with the exact tool/phrase diagnostic. Probe edits were restored before the final passing runs.
• Package formatting and git diff --check passed.
