- Migrated model catalog fetching and documentation references from the models.dev API to the stencil.so well-known models endpoint.
- Added support for zstd decompression and session-based caching with ETag conditional requests and stale fallback handling.
- Updated test suites, mock URLs, and constants across catalog and coding-agent packages to target stencil.so.
- resolveOwnerScopedSessionKey's getOwners in the Python and JS executors
only read live sessions, so a subagent reset issued while the shared
kernel was still starting resolved to the base key, awaited the
parent's startup, and shut its brand-new kernel down.
- Python and JS starting sessions are now owner-bearing records like
Ruby/Julia's: owners attach synchronously before startup resolves,
getOwners and per-owner disposal consult them, and the final
sessions.set is identity-guarded so a disposed starting record cannot
resurrect its kernel.
- Regression: deferred PythonKernel.start proves a concurrent subagent
reset forks immediately and never reaps the parent's starting kernel
(fails with the previous getOwners).
- Subagents inherit the parent's eval session id, so a child's
reset: true destroyed the co-owned kernel and every sibling's
interpreter state mid-session.
- resolveOwnerScopedSessionKey now routes a reset from a non-exclusive
owner onto a deterministic per-owner fork key: the requester gets a
fresh private kernel, co-owners keep the shared one, and the fork
stays sticky for that owner until its teardown reaps it.
- Applied across Python, JavaScript, Ruby, and Julia executors; JS
contexts gained an owner registry plus disposeVmContextsByOwner,
wired into EvalRunner.disposeKernels and SDK session teardown.
- Covered by pure key-resolution contracts and an end-to-end JS test:
co-owner reset forks, shared state survives, fork is sticky, and
per-owner dispose reaps only the fork.
- The earlier EBADF 'hardening' was chasing a Bun 1.4-canary quirk that
only triggers when bun test runs workspace-package files from the repo
root; the canonical runner (scripts/ci-test-ts.ts) always uses the
package cwd, where the original PR-authored pipe-based assertions pass.
- Restores the stronger stdout contracts from PRs #7135 and #7141.
- The IRC wake monitor from PR #7108 calls the observer on every kept-alive
subagent finalize; fakes across the executor suites predate the method
and threw during finalization (69 failures).
- Bun 1.4 canary's posix_spawn intermittently rejects pipe-backed child
stdio (EBADF) inside test workers, failing telemetry-export and
shell-snapshot probes before their assertions ran.
- Probes now spawn with ignored stdio and capture output via exit status
or temp-file redirection; all behavioral assertions retained.
- #7163's context-token anchoring re-triggered #7153's dead-end warning on
the pre-prompt pass; a one-shot marker now spans agent loops and re-arms
only when a persisted cut point appears.
- Updated scrollback tests to the Alt+L display-reset binding main adopted.
