Vitest resolves the shim's `buffer` import to Node's built-in module, so
the differential spec patched and then compared the same implementation.
Mock node:buffer with the npm package the Worker bundle uses. Also keep the
UTF-8 encoding check symmetric, call the package methods directly, and
document that the patch applies to every Buffer user in the Worker.
The Web preview Worker converted multi-megabyte combo scripts and source
maps with the buffer package's JavaScript UTF-8 codec, and the page
re-encoded each source map to Base64 in JavaScript before running the
bundle. Use TextEncoder/TextDecoder for whole-buffer UTF-8 conversions
and FileReader for the inline source-map data URL.
The packer images the web template bundles, every optional bundle, and an installation manifest instead of a dumped composition, and the Worker boots that profile through app-boot like dsh web. Package-local lazy client chunks move into content-addressed archives that the VFS fetches on first asynchronous read; client-modules reads chunks asynchronously.
The Worker replaces node-addon-require-builtin with Node v24.18.0 internal-module interfaces and reports Node 24, so plugin metadata, the Cordis Loader, and HMR reach one cascaded loader backed by the Worker loader. Resolution failures carry Node error codes, the empty load cache lets HMR apply profile changes, and every optional bundle switches on and off live. Platform stubs throw ERR_FEATURE_UNAVAILABLE_ON_PLATFORM.
pi-ai 1.0.0 adds Sign in with ChatGPT to the `openai` provider, and that
login refuses to start unless the app supplies a stable installation UUID
through LoginOptions.getDeviceId. The harness keeps no installation ID
meant for a third-party account sign-in, so the route offers its API-key
login only; a Loader-composed test pins the offered methods.
catalogProvider(), catalogModels(), and catalogProviderIds() now read one
index that leaves out providers without a chat model, so a hand-declared
route under such a key inherits nothing from pi-ai. The browser-worker
stub gains the builtinModels refusal llm-pi-ai imports and drops the
getBuiltinProviders reader nothing imports. The tool-argument streaming
spec also covers the patched Anthropic Messages path.
* fix(webworker): load plugin manager and HMR in the preview Worker
The Worker disabled both rows, which left Creator mode's
tool-plugin-manager waiting for its service and the Plugins page without
a manageable profile. Only package commands are unavailable; the
services load. The Worker provides appReady from its own readiness
promise, resolved once the tunnel serves, and its process shim reports
no entry script, so HMR keeps only its profile configuration watches.
Fixes#5372
* fix(webworker): show xdg-open text files in a preview viewer
The Worker implements xdg-open as a platform executable that sends one
VFS text file to the page, which shows it in a read-only modal dialog.
Settings' "Open configuration file" now opens the profile patch in the
preview instead of failing on a missing desktop opener.
Fixes#5371
Represent tool results as tool-role messages and migrate released wrappers
without losing outer own JSON fields, call identity, error state, or writer
field order. Refuse nested or wrapper-only information that has no lossless
current representation before successor publication.
Validate current event relationships directly instead of projecting V4 data
back into V3. Keep lifecycle, PTC, title/command, compaction, system-field and
retired-syntax checks on catalog restoration and ordinary JSONL opens. The
Worker JSON equality helper must inspect own keys so it cannot admit PTC
arguments that Node rejects.
Keep the source role change, required native admission and consumer fixture
updates in one complete review layer. Explain shared-type changes in the
persistence record and the native reader rationale in its existing note.
Use checked branded fixture identities and discriminant narrowing instead
of unknown double casts; fixture values and assertions remain intact.
This recomposes the original tool-role work by _Kerman with the independently
validated migration and admission repairs by Tianyi Cui. Frozen generations
and snapshot input version selection are retained.

The executor seam collapses run()/start() (and the planned begin()) into one
resolve() + execute(): the handle IS the live process, and the foreground
result, the background cursor, and the deadline's promotion offer are
projections over the same spawn. ShellExecSpec.onExpiry ('kill' default /
'offer' / 'none') replaces the implicit method split; one stdout budget applies
everywhere, the 'start ignores timeoutMs' wart dies, and sync spawn throws are
contained into the same settled-killed handle as async rejections (result()
rejects with the original error, identity preserved for the sandbox
classification).
The promotion offer settles exactly once and never rejects — offer at an
'offer' deadline while running, undefined when the process settles first — so
'await execution.promotion' alone distinguishes the outcomes. An offer must be
answered synchronously; an unanswered one auto-declines back to the
kill-on-timeout behavior. accept() ends the deadline and detaches the caller's
abort signal; decline() kills and classifies timedOut.
tool-bash and tool-pwsh promote on timeout by default (promoteOnTimeout: true,
inert without run_in_background or a job registry): at the offer the running
handle registers as a job with the same hooks as run_in_background, mirrors
into ctx.activities (the web task list streams it, stop control included), and
the call returns { kind: 'promoted', jobId, timeoutMs, output } carrying the
output so far — the job cursor continues exactly after it. Any promotion
failure declines and falls back to the plain timeout kill. Descriptions and
the timeoutMs schema text advertise the semantics only when they hold;
recorded-session and web snapshot fixtures re-recorded with them.
Also repairs the four CI failures from the human-kill push: ui-activity's
missing dsh-session peer declaration (static + windows observational), the
observe owner-arm/outer-catch and killJob-stub coverage gaps, tool-workflow's
owned-run arm, and the timing-dependent projection-cache interval flush test
(now poll-based for coarse Windows timers).
