Session logging is the one opinionated category that writes a persistent
record of terminal output to disk, and those logs can contain secrets.
Silent-by-default is the wrong posture for it, so C5 now defaults to off:
__fish_config_op_logging must be set to an explicit truthy value to enable
capture, and the master switch cannot enable it on its own.
Implemented as a single special case in __fish_config_op_enabled, so all
five capture components, the sentinel file, the paru/yay wrappers, the
Kitty watcher, and the config-settings TUI pick it up with no other code
changes. The existing startup sync in conf.d/logging-events.fish
reconciles the sentinel and removes the generated wrappers on the first
shell after upgrading.
BREAKING CHANGE: users relying on the previous default must now run
`set -U __fish_config_op_logging on`. Existing logs in ~/.terminal_history
are left untouched.
RETURNS previously conflated fish's $status exit code with genuine
stdout/printed output, e.g. rm listing "0/1" as if they were print
values rather than exit codes. Rename RETURNS to EXIT STATUS across
all 83 documented functions, and reintroduce RETURNS as a distinct
label reserved for the 15 functions that actually print to stdout.
Update build-manual.py's ENTRY_HEADS to render Exit Status before
Returns, manualtools.py's SECTIONS constant, and AGENTS.md's label
order and label-usage guidance to match. Add two verify-manual.py
regression tests: EXIT STATUS bodies must never contain stray
stdout/printed language, and Returns: must always render after
Exit Status: when both are present. Regenerate docs/fish-config.md.
