Rewrite the agent-scope RFC with executable examples and an explicit security non-goal. Harden subagent scalar and depth validation, and pin live tool-filter semantics across code, tests, and generated docs.
Queue worker results before settlement cleanup, claim terminal and death boundaries before provider callbacks, and close late-message admission.
Make child cancellation and disposal reentrancy-safe across the workflow bridge and generic subagent wrapper, with adversarial regression coverage and RFC documentation.
Make Cordis construction and teardown ownership reentrancy-safe, then carry caller and provider ownership through reservation, setup, publication, quiescence, and sentinel retirement.
Stabilize registry carriers and factory/workflow boundaries, add adversarial lifecycle regressions, and align the rewritten RFC plus generated contracts with the enforced behavior.
Every packages/*/* README now carries a canonical '## Known Limitations and
Deferred Work' section: condensed, evidence-backed bullets for consumer-visible
gaps (unimplemented features, platform caveats, MVP cuts) and consciously
postponed work (TODO/FIXME/XXX markers, RFC deferrals still open). The ten
pre-existing ad-hoc variants ('What is NOT here (TODO)', 'Deferred',
'Limitations (MVP)', 'Known limitations (tracked TODOs)', ...) are normalized
into the canonical heading.
A new doc-sync gate, scripts/verify-readme-limitations.ts, enforces the shape:
exactly one limitations-like heading per package README, byte-equal to the
canonical h2, with at least one bullet; near-miss headings fail so variants
cannot creep back. Packages with genuinely nothing to declare (dsh-brand,
dsh-timeout, dsh-subagent-mock, dsh-app-boot) are whitelisted in the script and
must NOT carry the section; whitelist entries are validated against the scanned
package set so a rename fails loud.
Wired into the doc-sync chain (package.json) and the run-gates doc-sync leaf
set; the standing rule lands in packages/AGENTS.md and the adding-a-package
cookbook; decision record in
docs/rfc/implemented/process/2026-07-10-readme-known-limitations-gate.md
(RFC index regenerated).
Also fixes two stale '(deferred)' markers claiming dsh-compact-basic is
unimplemented (the dsh-compact seam README's package table and the seam's
module doc comment).
Drain idle injection flushes before agent teardown, snapshot approval and subagent provider inputs, and gate subagent lifecycle events on real child readiness. Align the RFCs and generated contracts with the hardened behavior.
Review finding, valid — the previous SDK fix covered only the
non-default branch: in the default mode under Code Mode the wire filter
dropped exit_plan_mode but the registry-rendered tools:sdk section
still advertised its binding, offering default-mode agents a call that
can only error and breaking the byte-identical claim (a no-dsh-mode
deployment's registry never saw the tool, so its SDK never listed it).
The SDK re-render extracts to one helper both branches share: the
non-default branch passes the mode's visibility rule, the default
branch hides exactly the exit binding. The pinning test now compares
the default-mode SDK byte-for-byte against a bare deployment without
dsh-mode — the strongest form of the invariant the RFC states.
Review follow-up on the residual the previous commit accepted — and the
acceptance was wrong, because the fix is clean: in Code Mode the SDK
section IS the soft surface (the wire carries only run_code), section
text resolves in assemble's base, and renderToolsSdk is an exported
pure renderer. The outermost wrapper therefore re-renders tools:sdk
from the same visibility predicate the wire filter applies (allowlist,
exit-IFF-plan, minus run_code mirroring the registry's own exclusion):
a plan-mode program is documented exactly the callable bindings — read
and the exit, never the denied write. The default mode leaves the
section untouched (absence of policy), both pinned by tests.
The soft layer's promise — the model is never encouraged toward a tool
the gate denies — now holds in Code Mode too; the only remaining
prompt-honesty residual is a prepend-after-load assemble listener,
where the gate still covers execution.
Review finding, valid: under the registry's Code Mode the assembly's
only wire tool is run_code, which the plan allowlist filtered out —
leaving the model with NO tools at all, the exit review included. The
composition exists today (the acp-agent example ships a code-mode
overlay), so plan mode bricked it outright.
run_code is a transport, not a capability: every bridged sub-call is
serialized back through ToolRegistry.execute() carrying the same agent,
so tools/pre-execute judges each capability individually — exactly like
native calls. Both layers now exempt it by name: the filter keeps it
visible (tests pin plan-mode Code Mode assembly = ['run_code']) and the
gate passes the wrapper while the same run's write sub-call still
denies with the plan-mode reason.
Documented residual, same class as the prepend-after-load one: the SDK
section renders from the registry's store, so a plan-mode program may
be offered bindings whose dispatch the gate then denies — nothing runs
that a native call could not.
