Bring the node-addon-landlock-run tree (tag v0.0.1, commit 614f7fd) into
native/landlock-run as its source of record: launcher development happens
here, next to the harness consumers, and the standalone repository becomes
the release mirror the tree is exported to for packing and publishing
(procedure in native/README.md). The subtree keeps its own pnpm workspace
and lockfile and is NOT added to the harness workspace: harness installs,
gates, and CI never touch it. The mirror's .github/ stays out of the
subtree; a separate manually-dispatched workflow
(.github/workflows/landlock-run.yml) runs the subtree's CI legs — the
per-architecture native builds, real-kernel launcher proofs, and pack
rehearsal — adapted with working-directory/cache paths.
eslint ignores the subtree like vendor/; AGENTS.md gains the native/
layout line (+5 words on its budget ceiling).
Beyond line merges: python/sdk-runtime's deploy manifest gains
@deepseek-ai/dsh-mode — the single-exe closure gate
(verify-runtime-closure) requires every workspace peer of dsh-acp, and
the bridge's type-only peer edge on dsh-mode counts; the AGENTS.md
efficiency section is condensed to fit the 1820-word ceiling after
master's single-exe additions. Catalogs and graphs regenerated.
The stack rebases onto a moved master through its base branch. Beyond
mechanical unions (both branches' demo scripts, example rows, service
roles, tool lists, acp deps, doc budgets — each side fit alone, the
union needs the higher ceilings), three semantic reconciliations:
- The ACP bridge now carries BOTH per-session surfaces: the sandbox
stack's config options + approval answerer and this branch's session
modes; session/new and session/load advertise modes AND configOptions
side by side.
- The feature matrix supersedes the sandbox stance per the RFC's
second-lander rule: session/set_mode and current_mode_update flip to
shipped-by-dsh-mode, config-option rows stay as #169 wrote them, and
§6 records both landed features under the picker-to-modes /
knobs-to-config-options division.
- The snapshot pin grammar (#254: one header snapshot + declared deltas
+ a Markdown prompt golden) gains a symmetric declaration for what a
delta cannot express: expectedHeaderSnapshots — a plan-mode flip
resorts the canonical tool list, so its widening lands as a second
full snapshot, now its own Markdown section. The pin-less-class and
model-turn-only-pin amendments carry over; new fixtures cover the
extended writer paths, and the plan-acp-agent scenarios re-recorded
under the merged composition (the app now bundles the skill tool)
with the suite's refresh mode wired through.
Repeated full-repo gate executions in agent sessions traced to one
habit: piping a long command through a filter, losing the failure
detail, and re-running the whole gate to recover it — paying both the
gate again and an extra agent round-trip. The rule lands the full
output in a temp file, prints the summary, and auto-expands capped
failure context on non-zero exit in the SAME invocation.
Fits the existing 1802-word ceiling after condensing (1800).
Plan mode's stage 1 (RFC 2026-07-07-plan-mode): a new packages/mode/ group
with one product package owning the mode/set SessionEventMap vocabulary
(log-only, non-surface, whole-value replace), the pure foldMode, and the
ctx.modes service (list/get/set). User flips are pending intents flushed
at turn/start / step/end — turn enclosure makes an idle append illegal —
with one coalesced context/message notice when the flushed mode differs
from what the last logged request header told the model; a folded mode
the config no longer defines reads as default plus one boundary notice.
Enforcement is two covering layers: a system-prompt/assemble wrapper
filters the RETURNED assembly's tools to the mode's allowlist (and shows
exit_plan_mode IFF the folded mode is plan) beside the mode:policy
section at order 50, and a tools/pre-execute gate denies deny-by-default
against the same allowlist, judging by the logged mode only. The default
mode is the absence of policy — assemblies stay byte-identical to a
no-dsh-mode deployment.
AgentOptions.mode (declaration-merged) seeds a child's initial mode
through the same flush on agent/created; the stdio app gains /mode
(print/switch, never sent to the model) over an opportunistic
ctx.get('modes'). Config is an explicit resolve step: the built-in plan
definition (read-only allowlist; bash/subagent excluded until the
sandbox family lands) merges unless overridden, 'default' as a key
throws at load, unknown names throw at set() time.
Pure mechanical rename now that the package's internals are the
worker-thread engine: directory, package name, spec/e2e filenames,
module tags and logger prefixes, tsconfig/knip/run-gates/AGENTS.md
references, example cordis.yml plugin ids, doc links; catalogs
regenerated and the lockfile refreshed.
The outer ring catches up with the engine swap (the package's own
README/JSDoc rode the port commit):
- Seam module doc and README name the worker-thread engine as THE
implementation, with isolated-vm/separate-process sandboxing as the
deferred hardening; the seam service doc states the holder-owned-runs
contract (engine-fiber disposal deliberately leaves live runs to
their holders).
- Seam contract precision: agentsStarted documents the termination-path
degradation to the host-observed count; the events section scopes the
agent-start/agent-end pair to calls that STARTED a child run;
WorkflowRun wording drops the vm-era abandonment language.
- The dynamic-workflows RFC is rewritten in place to the shipped
mechanism (implemented-RFC rule): why worker threads, the thread's
concrete buys, the in-process node:vm first cut recorded under
alternatives considered; the tool section describes the usage policy
as the tool's own prompt section.
- gen-doc-graphs: six workflow/* DYNAMIC_EVENT_DISPATCHERS entries (the
catalog no longer claims nothing dispatches them) and the seam-note
wording; core-data-structures gains its workflow.md index row;
packages/README + AGENTS.md layout line + example cordis.yml comments
say worker-thread; catalogs regenerated.
In-place port of dsh-workflow-vm from the in-process node:vm execution
to one worker thread per run (the workflow-workerthread engine of
PR #215, adopted as THE engine): the script's vm context moves inside
the worker, agent() bridges to ctx.subagents over the message port
(host.ts/protocol.ts/session.ts/worker.ts are new; runtime.ts loses the
abandon channel — the host's grace timer force-settles and TERMINATES
instead), start() pre-parses the body host-side to keep the seam's
synchronous SCRIPT_PARSE throw, and a ready→go handshake keeps a run
cancelled before start from ever executing the body. start() no longer
blocks the host, termination is real, and the value boundary is
serialization by construction. The package keeps its name until the
follow-up rename commit; scripts see the identical hook surface, and
the seam-contract tests hardened ahead of this swap pass unchanged.
The run and child-RPC surfaces are class-shaped rather than literal
bundles: WorkerRun IMPLEMENTS the seam's WorkflowRun (id/meta are its
own clone, separate from event payloads') and start() returns the
instance directly — interface parity with the seam is compiler-checked;
worker-side, ChildRpcBridge (implements ChildPort; callId allocation +
pending book-keeping settled by onChild* entry points) and
RpcChildHandle (every member an RPC keyed by its callId) carry names in
stacks. ChildPort's method is startAgent — it names what it starts,
matching the script-side agent() hook and the agentsStarted /
workflow/agent-* vocabulary; the Child* type names deliberately stay
(the worker side is cordis- and subagent-free; these are reduced JSON
projections, not the seam's types).
Review findings from the reference PR are folded in rather than
re-introduced:
- cancel() drives BOTH child-cancel channels host-side: the request
signal aborts AND each registered child's explicit cancel() is
called — a worker wedged in a synchronous spin cannot relay its own
ChildCancel RPCs (regression: cancel-only provider + wedged worker).
- All host warn paths render through the total renderThrown; a child
dispose() rejecting a value whose coercion throws still acks
ChildDisposed instead of wedging the script's finally (regression).
- built-worker.e2e.ts is wired into builtBinSmokeGate and the AGENTS.md
CI sequence — the built lib/worker.js resolution contract now runs in
an automated gate.
- workflow/end payload pinned on the worker-death path (with the
cancelled and grace-force-settle pins riding the ported spec).
- Real-Worker scripted timing budgets widened (50-300ms → 150-1000ms)
for starved CI hosts.
Workspace plumbing: the "./worker" subpath export sanctions the second
runtime bundle (check-workspace-constraints), tsdown builds two
single-entry passes, tsx becomes a devDependency for the unbuilt worker
spawn.
Everything outside the package and example that a new top-level group and a
new demo touch: GROUP_ORDER in gen-module-graph and gen-doc-graphs (plus the
tools-service consumers list, the APP_EXAMPLES entry, and the graph-atlas
label/mode rows), the knip e2e entries, the packages/README group row, the
AGENTS.md layout and demo lines, and the regenerated module-graph /
config-catalog / graph-atlas / capability-seams / composition artifacts.
AGENTS.md and examples/AGENTS.md word-budget ceilings rise to current+5%
(1802 / 653): the new group and demo rows are genuine additions to both docs,
not condensable restatements.
The shipped backend of the code-execution seam, per the Code Mode RFC's
worker-thread section: one fresh Node worker per run, executing the
model's TypeScript after a host-side type-strip (wrapped in an
async-function shell so top-level return/await parse, sliced back out
position-preserved), bindings bridged over the message port under
hostile-peer rules (own-property name lookup, at-most-once replies,
post-settlement drops, null-prototype namespaces), logs streamed eagerly
with an in-band truncation marker, and two independent budgets — measured
event-loop busy time (computeMs) plus a never-pausing wall ceiling
(maxWallMs) — funneling into worker.terminate(). env: {} and execArgv: []
keep the isolate hermetic; disposal aborts in-flight runs and awaits
worker exits.
The worker entry loads unbuilt via Node's native type stripping
(src/worker.ts, erasable-only) and ships built as a sibling tsdown bundle
(lib/worker.js); tests/built-lib.e2e.ts pins the built load path under
plain node and joins the built-artifact smoke gate. Unit suites cover the
bootstrap in-process (fake port) and the runtime over real workers,
per-file 100%.
The tool-order feature canonicalizes the model-facing list (alphabetical
absent a configured toolOrder), so the header-pinning text-turn fixture is
re-recorded on the stacked tree — every other fixture stores the header as
scrubbed tokens and needed nothing. AGENTS.md condensed back under its
ceiling after the merge union.
