- Removed the exported formatBashFixupNotice helper from bash command fixup utilities.
- Removed BashTool's one-time bash-fixup notice tracking and stopped emitting those notices when fixups were applied.
- Updated `formatBashFixupNotice` to wrap the stripped-pattern warning in a `<system-warning>` wrapper.
- Reworded the notice to clarify output is already truncated and stderr is merged into stdout.
- Extended the Bash interceptor test to verify the warning tag appears for head/tail stripping.
- Added top-level parsing and segment splitting to apply bash fixups only on safe command chunks.
- Replaced `stripTrailingHeadTail` usage with `applyBashFixups` and array-based notice formatting.
- Fixed terminal `| head`/`| tail` and redundant `2>&1` stripping while preserving command semantics.
- Updated fixup tests for cross-command cases and removed superseded head-tail-only test coverage.
Drop trailing `| head [args]` / `| tail [args]` pipes that exist purely
to limit output — the harness already truncates bash output and exposes
the full result via the bash-original artifact, so these pipes only
hide content from the agent.
Conservative gates (any failing leaves the command verbatim):
- single-line only; multi-line scripts may legitimately end pipelines
with head/tail to bound a generator or loop body
- whitelisted limit-only args (-nN, -n N, -cN, -N, -q, -v, --lines[=N],
--bytes[=N], --quiet, --verbose); rejects -f/-F/+N/filenames so
`tail -f`, `tail -n +2` etc. stay intact
- regex anchored at end of command; any downstream operator (`&&`,
`||`, `;`, `&`, `>`, `|`, `` ` ``, `$(…)`, `)`) blocks the match, so
`just build 2>&1 | tail -3 && just up && …` is untouched
- refuses to reduce the command to an empty string
- pipe boundary uses `[ \t]*`, not `\s*`, so a `|` on a continuation
line cannot be swallowed
Consolidates the existing `timeoutClampNotice` and the new strip notice
into a single `pendingNotices: string[]` array threaded through every
execute branch (async, auto-background, ACP terminal, local exec).
New setting `bash.stripTrailingHeadTail` (default `true`).
