Spawns one non-interactive child against the sandboxed config and asserts on
what loaded -- abbreviations, key bindings, bang-expansions, the C5 event
handlers and the tailscale completion machinery must all be absent. Exit
codes name which guard regressed. No wall-clock assertions, so it cannot
flake.
docs/fish-config.1 is left for CI to regenerate: the local pandoc is 3.10.2
against CI's 3.1.3, so rebuilding it here emits ~4700 lines of formatter
churn unrelated to this change. The component registry rebuilt identically.
Follows the relocation out of conf.d/. The completions/ branch of the file
tree is expanded from the real directory at build time, so it needs no
hand-written children. Generated docs are regenerated separately.
Neither file defines a function or sets a global; their only effect is
writing ~/.local/bin/<tool>, which every interactive session does anyway.
Combined 10.7 ms off every fish -c.
__fish_config_sync_logging ran on every fish -c, mkdir+touching the C5
sentinel on disk from every subshell. Its consumers — the Kitty watcher and
the paru/yay wrappers — are interactive-context, and every interactive shell
still reconciles the state.
The --on-variable PWD handler backgrounds a git fast-forward. A script that
cd's was firing it, which is also where AGENTS.md Task #4's credential
prompt could surface from a background job.
fish_color_* is consumed only by the syntax highlighter. The guard sits
below the existing cleanup branch so stale-FZF_DEFAULT_OPTS cleanup keeps
running where it does today; the FZF value itself is a persisted universal
and survives regardless.
Defines fish_prompt only. The guard precedes the op-guard and the type -q
PATH scan so both are skipped in scripts. Scripts fall back to the repo's
autoloadable functions/fish_prompt.fish, which nothing invokes anyway.
Thirteen lines, every one a `complete -c cheat` registration, sourced on
every shell start from the wrong directory. Startup cost was already ~0
because its command substitutions are lazy, but completions/ is where fish
expects the file and the move is free.
The Cobra-generated block ran `complete --do-complete "tailscale "` to flush
pre-existing completions before erasing them, which executed the tailscale
binary. From completions/ it has no job: fish autoloads only the first match
on $fish_complete_path and the repo's completions/ precedes the vendor dir,
so the vendor file is never sourced.
Verified byte-identical completion output across four probes with the vendor
file present. A comment at the deletion site records the reasoning.
conf.d/tailscale.fish is 252 lines of Cobra-generated completion that fish
sourced on every shell start, and its self-priming block executed the
tailscale binary to warm the completion cache. completions/ is the directory
fish autoloads on first <TAB>.
Measured: 19.2 ms off both interactive and non-interactive startup.
