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).
Model-facing tool-call budgets were tangled into each capability's schema
(bash timeoutMs, web_fetch timeout_ms) with no shared home. Add a
tools/execute around-dispatch waterfall to dsh-tools whose base next() is
the dispatch-with-normalization thunk, and a new @deepseek-ai/dsh-timeout-policy
plugin (packages/timeout/) that arms a per-tool deadline on exec.signal and
returns a structured TOOL_TIMEOUT when it wins. Migrate web_fetch (drop the
model-facing timeout_ms) and web_search onto it; the fetch provider keeps its
timeout only as a resource backstop for direct callers. bash and hook command
execution keep BASH_TIMEOUT unchanged.
Named the plugin timeout-policy (not the RFC's tool-timeout) so it does not
trip the gen-tool-catalog packages/*/tool-* completeness guard, and replace
exec.signal by in-place mutation before next() since cordis waterfall next()
ignores passed arguments. RFC moved to implemented/ recording both deviations.
New doc-sync gate verify-export-jsdoc walks every module-level exported
name under packages/*/*/src and requires description prose everywhere,
plus @param per parameter and @returns on non-void annotated returns for
function-like exports, public class methods, properties, and accessors.
The parsing + check helpers move out of gen-cordis-catalog.ts into a
shared scripts/jsdoc.ts so 'documented' means one thing on both gated
surfaces.
Deliberate exemptions (documented in the RFC): heritage-declared class
members (the seam declaration is the doc's one home — the one checker
query in an otherwise pure-AST walk), cordis plugin-protocol slots
(name/inject/reusable/Config/apply, top-level and static), constructors,
overload implementations, declare-module augmentation bodies, and
re-export statements (checked at the defining module).
The 203 under-documented exports the gate found at adoption are filled
in this change, so the gate lands green; generated catalogs/graphs are
regenerated for the shifted line pointers.

Round 2 P2: timeoutOf() accepted ANY TimeoutReason, so under nesting — when
the upstream handed to deadline() is itself a deadline (the RFC's named
tools/execute middleware follow-up) and its outer timer fires first —
AbortSignal.any preserves the outer reason and the inner bash/web would report
the outer timeout as their own (timedOut / WEB_FETCH_TIMEOUT) though their local
timer never expired. Add an optional code to timeoutOf; bash and web pass their
own code, so a foreign timeout falls through to the upstream-cancel path.
Timeout timing/classification was re-implemented three ways across the
tool-bearing capabilities, with the fusion of timeout+cancel and the
timeout-vs-cancel reason recovery being the error-prone parts. Extract that
shared half into a zero-dependency @deepseek-ai/dsh-timeout library
(clampTimeout/deadline/timeoutOf/TimeoutReason) and leave the non-shareable
hard-kill in each capability, per the timeout-library RFC.
bash: run() owns the deadline; runBash drops its killTimer and no longer
classifies (SpawnSpec/SpawnOutcome lose timeoutMs/timedOut/aborted), so the
public timedOut/aborted booleans become mutually-exclusive first-abort
classifications. web_fetch: the hand-rolled controller/timer/listener/
signal.reason dance is replaced by provider-owned deadline/timeoutOf, keeping
the WEB_FETCH_TIMEOUT / WEB_ABORTED contract. fs stays timeout-free (README
states why).
WebService exposed an observation surface nothing in production observes:
the web/providers-change event (declared, emitted on every provider
registration/disposal, rollback-yield ordered before the emit solely so a
throwing change listener unwinds the registration) and the aggregated
searchStatus()/fetchStatus() query with its WebCapabilityStatus union.
dsh-tool-web executes through ctx.web.search()/fetch() and routes on the
structured WebError codes selection throws at execution time; tool
registration follows product enablement, not provider availability. The
only listeners/callers were the web packages' own tests, and the
tool-web README / architecture.md prose claiming the tool 'reads only the
aggregated searchStatus()/fetchStatus()' had drifted from the call sites.
Remove the event declaration, both emits, and the rollback-before-emit
machinery (the plain ctx.effect disposer keeps HMR cleanup, matching
LlmService.registerAdapter). Remove searchStatus()/fetchStatus(),
resolveStatus(), and WebCapabilityStatus; the provider-private status()
stays as the execution-time selection input. Delete the listener-throw
rollback test, and rewrite every event/status assertion across the web
packages' tests onto caller-observable behavior: a successful
search()/fetch() or the structured WEB_PROVIDER_* codes. Regenerate the
cordis catalog; update the web/tool-web READMEs, the architecture.md web
paragraph, core-data-structures/web.md, and the type-equiv manifest; amend
the web capability seam RFC's facts to the shipped surface. This follows
the llm/adapter-change precedent: a boot-time backend-registry signal and
an availability probe distinct from executing both sit on the cut side of
its keep/cut criterion.

- search providers (exa/perplexity/deepseek): map the parsed response
INSIDE the parse try, so a well-formed body of the wrong shape surfaces
as WEB_PROVIDER_ERROR instead of escaping as a raw TypeError; a WebError
the mapper throws on purpose is re-thrown untouched
- web-fetch-local: validate numeric limits at plugin construction (positive
finite caps; non-negative integer maxRedirects) rather than constructing a
provider with nonsensical values
- web-fetch-local: enforce the redirect budget BEFORE resolving each hop, so
maxRedirects:N follows exactly N redirects and an over-limit hop reports
"exceeded the maximum" rather than misdiagnosing a cross-origin block
- drop the stale dsh-tool-web/search and /fetch path aliases (the package no
longer declares those subpath exports)
- strip trailing EOF blank lines flagged by git diff --check
Each fix carries a regression test.
The web packages were authored against the old single-stage layout where
tsc emitted directly to lib/. Master compiles declarations to lib/types/
via tsc -b, then bundles JS into lib/ via tsdown. Point every web package's
tsc outDir at lib/types, update package.json types/exports/files to the
lib/types declaration + lib/ bundle shape (matching dsh-bash/dsh-tool-bash),
and bundle tool-web's subpath entries from lib/types/*.js rather than src.
The function carried two consecutive JSDoc blocks; the first was an
outdated short version missing the timeout-recovery contract. Keep only
the accurate detailed block.
Resource-lifecycle and error-classification fixes in the local fetch provider:
- Classify a timeout that fires DURING the body read as WEB_FETCH_TIMEOUT, not
WEB_ABORTED: thread the controller signal into the body-read translate path
and recover the timeout WebError from signal.reason, honoring the public
WEB_FETCH_TIMEOUT contract for a stalled response body.
- Cancel the response body before every blocked-redirect throw path
(cross-origin, invalid target, missing Location), so a rejected redirect with
a large or streaming body does not leak the socket after the tool returns
WEB_REDIRECT_BLOCKED.
- Cancel the body when charset validation fails, matching the
unsupported-content-type and over-size paths (the round-1 charset check threw
before readCapped owned the stream).
- Re-validate redirect targets through validateFetchUrl before following, so a
same-origin Location carrying credentials (or a non-http(s)/over-long URL)
cannot bypass the transport hygiene a direct request enforces.
- Treat only DROPPED bytes as truncation: a body exactly at maxResponseBytes is
no longer falsely flagged truncated (which emitted a spurious footer).
- Honor the declared response charset: parse the Content-Type charset and decode
with it (rejecting unsupported labels as WEB_UNSUPPORTED_CONTENT_TYPE) instead
of always assuming UTF-8 and returning replacement characters.
- Catalog the web seam vocabulary in docs/core-data-structures/web.md with
type-equiv blocks + manifest entries, per the core-data-structures rule.
Introduce web access as a first-class capability seam so the model-facing
web tools stay stable while backends change. dsh-web owns ctx.web as a
provider registry with registration-order-independent selection and the
WebError taxonomy; dsh-web-search-exa, dsh-web-search-perplexity, and
dsh-web-fetch-local register capabilities into it; dsh-tool-web is the sole
owner of the model-facing web_search/web_fetch schemas, prompt sections, and
HTML-to-markdown presentation. Search and fetch are deliberately one seam.
Providers ship as namespace plugins that register into ctx.web (like an
LlmAdapter into ctx.llm), not key-owning services, since multiple search
providers cannot each own the key. Tool registration follows product
enablement, not backend availability, so load order/credentials never enter
the model contract; the seam resolves the provider at execution time and
surfaces a structured WebError otherwise.
Moves the RFC to implemented/ amended to match what shipped. Example/app
configs are intentionally not wired yet (RFC migration step 6).
