Apply the AGENTS.md comments guideline to every .ts under tests/: remove
what the code already expresses, keep only what it cannot.
Removed: spec-header coverage inventories the describe/test tree already
names; comments restating the next line's assertion or its message; helper
JSDoc whose body already says it; within-file duplicates; five stale
claims (trendChart's "six aggregated turns" against agg.length === 8,
agentGraph's "six categories" against CATS' seven, fold-timing's "cheapest
call LAST" against a loop that feeds it first, fold-surface's unreachable
plain-JSON note, contextView's "two turns" for a one-turn fixture).
Kept and condensed: the projection-freeze class, strict wire/state-schema
hazards, retention and pricing windows, pairing rules, hostile-input
rationale, fixture and expectation-array ground truth, jsdom mechanics,
and issue-numbered regressions.
Comment lines 2604 -> 2014 (-22%); 85 module headers kept, 30 coverage
inventories dropped; every surviving comment line is within the 140-column
limit, with 36 wrapped lines joined onto fuller ones.
No logic, string, identifier, import or directive changed: a comment-strip
gate proves each file's comment-free code is byte-identical to HEAD, and a
line-level proof pairs all 845 changed lines with an unchanged code part.
pnpm run lint && pnpm run test (106 files / 2061 tests, per-file 100%
coverage) && pnpm run build all pass.
The old suite exercised the built lib/ bundle, so v8 remapped almost
nothing (8% src coverage) and every run needed a build first. The new
suite imports src/ directly under two vitest projects (node for
host/shared, jsdom for client), rendering real React 18 trees against
the real dictionaries and ui-primitives, with faithful in-memory
harness faces (cordis inject/effect, locale chain, slots, sessions
provide) instead of plugin mocks.
- 43 fine-grained, stateless, single-module spec files (606 tests)
forked across workers: ~2.5s wall, no build step
- v8 thresholds at 100/100/100/100 per file over src/**
- host specs drive the real projection definitions (init/apply/view)
plus one full cordis + SessionStore + SessionProjectionRegistry
integration; the framework's snapshotJsonValue pins the
projection-cache precondition on every intermediate fold state
- oxlint's src ruleset now covers tests/** as well
- typecheck covers the tests via tsconfig.tests.json
