Unix PowerShell emits cursor-position requests while PSReadLine starts and
redraws prompts. The subprocess PTY is only a transport, so those requests
went unanswered. Startup could then accept the dsh> literal echoed from its
setup source as a rendered prompt, and later sends were lost or clipped.
Feed raw PTY output into a zero-scrollback @xterm/headless state machine and
write generated replies through the provider-owned terminal handle. Drain
replies before caller input, repeat foreground inspection when terminal
activity races the sample, and retain send ownership until parser and reply
work quiesce. Coalesce raw chunks behind one active parser write so large
Windows output cannot create thousands of queued parse callbacks.
Publish pwsh only from backend stdin_read evidence and start one timeoutMs
deadline before the complete startup retry loop, so inferred-idle follow-ups
cannot reset the bound. Dispose the emulator when the
terminal or cleanup fails. Document the fail-loud ConstrainedLanguage path
and add focused coverage for split queries, reply ordering, foreground
resampling, failure containment, batching, timeout, and disposal.
tool-bash-persistent overwrote the backend's PS1, so terminal-bash prompt
readiness never matched and every send degraded to the 3.5s silence tier
(idleSilenceMs + handoffGraceMs) under production defaults.
The controlled PROMPT_COMMAND now re-asserts PS1 before every prompt, so an
in-shell override never survives to the next prompt. The tool initializes
with stty -echo alone and detects the no-end-marker fallback through the
seam's stdin_read wait reason instead of matching its own prompt text.
Tool calls drop from 7180/3560/3566 ms to 355/88/91 ms (spawn+init+echo,
echo, pwd; darwin, production defaults). The loader composition suite now
pins the fast path by pushing idleSilenceMs beyond the send bound, and a
real-PTY case proves PS1 self-healing.
Fixes#2585
Every release member now declares publishConfig.access: public, so the scope no
longer mixes levels: the 221 packages/*/* and apps/* manifests join the vendored
framework and the native packages.
check-workspace-constraints drops the per-sequence expectation and holds every
release member to public, which is what stops a member from drifting back.
Access is a property of the package, not of a version: the dsh packages already
published as restricted become world-readable at their next publication.
The three release sequences shipped with publishConfig.access: restricted, so
nothing in the @deepseek-ai scope was installable from outside the organization.
A restricted dependency is what actually blocks a public consumer: every harness
package declares the vendored framework as a peerDependency, and
dsh-sandbox-local declares the Landlock entry as a dependency. Those two
sequences therefore go public first — the nine vendor/* packages and the three
native/landlock-run packages — while the dsh family stays restricted until its
own sequence is opened deliberately. No public package requires a restricted one
in this arrangement.
Access is now per sequence, so no publish path can pass --access: one flag
cannot express two levels and would override the manifest that owns the fact.
publish.ts stops passing it, matching the native workflow, and
check-workspace-constraints holds each manifest to its own sequence's level,
which is what stops the scope from drifting one package at a time.
Harness consumers reference the Landlock entry as workspace:^ instead of
workspace:*, so a published harness package accepts the entry's patch and minor
releases. The entry keeps workspace:* for its platform packages, where the
binary must match the entry version exactly.
Two rationales that named a private registry no longer describe the vendored
sequence; they now state the durable reason, which is that the verification must
not depend on the registry already carrying matching versions.
