Consolidate repeated tooling flows while preserving command contracts. Fix swallowed HTML translation errors and browser-realm error handling in the Google Live smoke. Owner tests and CLI parity passed on Testbox; final broad gate replay follows a fixture lint correction.
Artifact and tool acquisition can recover from provider transport errors
without repeating tests. Existing recovery paths did not consistently
identify these attempts in GitHub annotations.
Emit warnings only when infrastructure recovery fires, preserve immutable
inputs and budgets, and keep terminal errors fatal. A synthetic HTTP 503
then 200 probe retained the exit status and produced one warning; a normal
download produced none. Owner tests, syntax and workflow checks passed.
* fix(scripts): use system Bash for macOS tooling and owned Mach-O fixtures
Pin native entrypoints and package commands to /bin/bash, guard portable heredoc callers on Darwin, and preserve Bash 3.2 boolean parsing. Streamed installers explain how to use system Bash when their input cannot be replayed.
Generate deterministic x86_64, arm64, and arm64e framework fixtures instead of borrowing /bin/ls. Preserve the existing framework pipeline repair from #141056 and verify merged slice bytes.
* fix(scripts): keep guarded portable scripts bash 3.2 compatible
* fix(scripts): keep macOS Bash CI coverage green
Distinguish sourced installer returns from stdin exits without ShellCheck unreachable-code warnings. Retain the shebang regression suite in changed-target routing, and repartition hosted tooling tails toward 50-second groups within the existing 150-second budget and 80-job cap.
Validation: 635 interpreter and routing tests plus 53 planner tests passed; ShellCheck, targeted lint, formatting, and fresh Codex review passed. The broader local changed-file check hit an unrelated existing dependency graph crossing through extensions/reef/node_modules/@noble/hashes; exact-head hosted CI remains required.
* docs(install): use system Bash in install and recovery commands
Align macOS-facing copy-and-paste commands and emitted installer guidance with the supported streamed interpreter. This addresses the remaining installer-command review finding without changing the PR body.
Validation: streamed help for both installers, install.sh dry-run, 16 selected fresh-install and upgrade lifecycle tests, formatting, diff check, and fresh Codex review passed. Landing remains blocked by unrelated provider-transport integration CI failure caused by an unchanged incomplete plugin-registry mock.
* fix(scripts): preserve streamed installs and CI packing
Keep public installer commands portable while replaying Darwin Bash 5.3+
stdin under system Bash through an immediately unlinked private temp file.
Retain actionable sourced-install rejection and the SC2317-safe check.
Restore the original CI packing policy and move the Bash policy scan into
its existing macOS tooling owner without adding a routed test file.
Validation: real Homebrew Bash streamed help and cleanup; 642 scan/routing
tests; 23 selected installer tests under both PATH orders; planner cap and
coverage tests; 139 Bash syntax checks; ShellCheck; 1,135 changed-gate tests;
focused lint/changed-check repair; fresh Codex review with no P0/P1 findings.
