## Notable commits

- fix: chore(scripts): delete fix-async.ps1 and launch_daemon_detached.py
- fix: chore(ship): move the plugin-impact baseline past the VS Code fixes merge
- fix: fix(analysis): read the val line behind the MCP result prefix
- fix: fix(build): build.fsx fails the test target on any non-zero exit
- fix: fix(cohort): a landing is verified against the files evaluated over the build, not coverage alone
- fix: fix(cohort): a member's public id is a fingerprint of the connection handle, not the handle
- fix: fix(dashboard): bound the eval result block, and keep a following output panel at the bottom when its own box changes size
- fix: fix(dashboard): give every held row of the live-bindings pane a signal of its own, and wait on the clicked row's mark
- fix: fix(dashboard): the live-bindings layout check judges the rows that have a box
- fix: fix(gate): a test whose coverage hit nothing has no cache key, so it is always run
- fix: fix(gate): a test's cache key sees the files coverage cannot, trustBeyond and seenFiles
- fix: fix(gate): gate-reap.fsx loads MachineTier.fs before Timeouts.fs
- fix: fix(hot-reload): keep the delta emitter inside two architecture ratchets, and make the child's protocol a closed set
- fix: fix(hot-reload): latency tier follows a patched save from its own compile, and takes the files as the journeys left them
- fix: fix(hot-reload): the REPL-freshness wiring fits the repo's ratchets and its wire shapes are pinned
- fix: fix(hot-reload): the emitter folds line numbers out of field and helper-method names, found by a real F# build
- fix: fix(hot-reload): the latency tier's restart row measures a restart, and a delta row measures the default route
- fix: fix(hygiene): the always-loaded skill stays under its word budget, and the browser journey disposes by await
- fix: fix(lemmings): Neovim harness types ;; whole, keeps the editor shell off the harness, and says what it needs
- fix: fix(lemmings): Neovim oracle follows what real runs showed
