Contain arbitrary plugin and runtime failures even when a thrown Proxy traps instanceof checks or its string coercion throws. Fall back to a stable diagnostic instead of letting executeCli reject outside its exit-code contract.
Route abort reasons through the same total renderer so cancellation cannot escape containment through an exotic reason value.
Add a focused regression that exercises both hostile inspection paths and verifies stdout remains empty, stderr remains labelled, and the CLI resolves with exit code 1.
Report context-disposal failure as an independent outcome even when argument, boot, task, or output handling has already produced a primary diagnostic.
Keep the primary error first, append the cleanup error, and retain the nonzero exit status so operators can see both the initiating failure and the possibility that teardown or persistence did not complete.
Add a regression that combines an invalid app composition with a failing disposer and asserts both ordered stderr lines.
Align the one-shot app with the shared agent-spine contract that landed on master after this branch began. Expose maxParallelToolCalls, dshHome, toolBash, and toolTasks through the Loader schema and route them with pickSpineConfig().
This restores deployment control over tool-call concurrency, the shared Harness home, background bash, and task_output wait bounds instead of silently retaining owner defaults.
Exercise all four fields through the composed runtime, document the package-level contract, and regenerate the config catalog from the owning interface.
Race Loader startup with the process abort signal so SIGINT and SIGTERM can settle the one-shot CLI even when initialization has not returned a Context.
If boot settles after cancellation, dispose the late context asynchronously instead of recreating the wait. Contain late boot rejection and report a late disposal failure on stderr.
Cover prompt interruption, late context disposal, late boot rejection, and cleanup failure with focused CLI regressions.
Refresh PR #380 against master at ab96fdb63 immediately before landing so the admin merge is evaluated against the current repository contracts rather than the branch's earlier base.
Take the merged SQLite owner-only permission hardening and its regenerated config catalog while preserving the examples/repl-agent rename. The merge leaves examples/coding-agent absent and keeps demo:repl wired to the renamed leaf.
