The web YAML editor is gone. agentPreset.write (arbitrary composition
text) became agentPreset.copy { from, agentPreset, name? }: a host-side
whole-directory copy of ids the host resolves itself — symlinks
dereferenced, modes re-tightened to owner-only with owner-execute kept,
metadata rewritten to keep the source's description but never its name or
roster order. No composition text or path crosses the wire in either
authoring direction, and the entryListSchema/!!js concern dissolves with
assertComposition itself.
The settings section becomes: a read-only viewer over shipped
compositions, a copy dialog (id + optional display name) as the only
create entry, delete for custom rows, and a location action leading into
the preset's own files — agentPreset.openDocument { agentPreset } resolves
the directory host-side and opens it natively, or answers
{ opened: false, path } for the row to show as text where the deployment
has no desktop. agentPreset.list reports hasDocument beside authorable;
the gateway's nativeOpen config pins the capability where
canOpenNativePath platform detection would mislead. The privileged set is
now read/copy/openDocument/remove.
With files as the only composition editor, standing mounts grew
stamp-keyed generations: ensureStanding compares the composition file's
mtime+size and starts the next generation for later sessions, while every
joined session keeps the generation it runs on.
New keyless web lane (agent-preset-authoring, overlay pins
nativeOpen: false so goldens render one branch on every platform) drives
view/copy/reveal/delete end to end; the real-composition CLI e2e switches
to copy semantics.
The serializer's undefined-tombstone branch (from the seam's
NodeJS.ProcessEnv migration) removes an ambient entry; the composition
env test now exercises it against the scrubbed ambient KEEP entry.
The linear replay carried old-lineage content over parent-owned files;
this checkpoint restores them and adapts the branch to the parent's
post-rebase seam:
- restore all pty/lsp/subprocess/code-runtime surfaces to the parent's
exact content (this branch claims none of them) and drop the net-zero
code-runtime-e2b/pty-e2b/lsp-e2b residue and its registrations
- widen serializeRemoteEnvironment to the seam's NodeJS.ProcessEnv
tombstone contract: an explicit undefined removes an ambient entry
- migrate the two E2B fixture Agent stubs to the Inbox-model interface
and Session.create
- re-apply the branch's gen-doc-graphs roles, THIRD_PARTY_NOTICES e2b
row, and packages/README group row (trimmed to the doc budget);
regenerate catalogs and re-record bilingual pairings
Master's steering-receipt API (agent.steer returns SteeringReceipt) reached
this branch through the parent sync; the two E2B live-fixture Agent stubs
return the same rejected-outcome receipt the pty test stubs use.
- subprocess-e2b: the 20 ms remote poll cadence becomes a validated pollMs
Config field (each tick is one control-plane request); the README documents
the latency-versus-request-count trade.
- subprocess-e2b: extract src/remote.ts owning asError, signalOpts,
commandOpts, delay, waitTick, and one tolerant signalRemoteGroups shared by
the pgid-keyed process ladder and sid-keyed terminal ladder, so the two
teardown paths keep identical error tolerance.
- subprocess-e2b: service disposal aggregates sibling cleanup failures into
one AggregateError instead of discarding all but the first.
- subprocess-e2b: waitForProcessGroupId refuses published group ids <= 1, so
a same-UID rewrite of the pid file cannot aim termination at kill -- -1;
README documents the same-UID control-state limitation.
- subprocess-e2b: drain-grace expiry now releases an inherited-output E2B
callback blocked on host backpressure before disconnecting, so the SDK
settlement cannot stay pinned behind an unread host stream.
- subprocess-e2b: spawn/spawnTerminal stop validating typed spec fields
(trust-TypeScript rule; pty-local validates its config before specs exist);
resolveExecutable rejects separator-containing relative paths per the seam
contract; terminal setups tracked as a Set of records.
- subprocess-e2b: PTY output push-without-backpressure is a documented
contract (flowing consumer folds bytes; paused consumer buffers).
- fs-e2b: streamText normalizes the pinned SDK's empty-file '' return into an
empty stream instead of throwing on getReader().
- e2b overlays: comment the one-world cwd invariant across e2b.cwd,
workspaceRoot, and bash-local's implicit default workdir.
E2B starts command and PTY requests through login shells, so isolate each control shell behind a fresh randomized HOME and blank sandbox credential names before mutable profiles can run. Preserve the real remote HOME only for the requested argv.
Collapse duplicate termination state, keep failed force cleanup retryable until quiescence is observed, and make terminal state allocation cancellable. Leave numeric PGID reuse as an explicit provider-level TODO because a userspace precheck would remain TOCTOU.
A recycled shell pid could donate an unrelated process's children to the
terminal session's cleanup signalling: post-exit rescans queried
processTree/processSession by numeric pid alone. The handle now captures
the spawned shell's start identity at construction and adopts newly
scanned members only while the root pid still carries it; already-adopted
members keep their own identities, which every signal already rechecks.
Regressions cover a recycled root donating an imposter child and a shell
whose identity was never observable; the terminal fakes now model the
root row the real /proc and ps scans include.
Also from the review round: tool-pty's dependency list is re-sorted, and
the LSP renderer documents the deliberate drive-letter reading of
ambiguous file: URIs (display-only blast radius).
workspace-write now runs [logon SID, Everyone, orphan]: the two lists differ only by the orphan, and the keep-alive group (logon SID + Everyone) is the single shared invariant. The WMI namespace security check fails in BOTH modes (0x80041003), so CIM/Get-ComputerInfo are unavailable everywhere — the price of closing the C:\\-root tree-creation escape (AU:(AD) + AU:(OI)(CI)(IO)(M)) in workspace-write too. The unused WinLocalSid/WinInteractiveSid/WinAuthenticatedUserSid constants and their ABI-probe prints are removed; the enforcement 'full' claim now stands on a closed NTFS surface. New regression: a C:\\Users\\Public subdirectory write is denied under BOTH modes (the ambient-writable blind spot the review flagged — INTERACTIVE is absent from both lists). FAT-class (non-ACL) targets outside the granted roots remain writable (no security descriptors to intersect) — documented as a legacy residue, warn-only, not engineered around. Docs/design note/PR body updated in both languages (list I/J terminology gone everywhere).
Restores master's vitest config and packages-README pairing record (the
replay had carried old-lineage copies; this branch claims neither), and
regenerates the doc graphs, catalogs, and architecture pairing the
replay's ours-side resolutions had flattened to master's content.
