gen-cordis-catalog now hard-errors (aggregated, not fail-fast) when an
event lacks description prose or a payload @param, or a public service
method lacks JSDoc, a @param per parameter, a @returns on a non-void
result, or an explicit return type annotation. The this receiver and the
trailing waterfall next are exempt on events (mode machinery owned by
@mode); a stale @param naming no real parameter errors, mirroring the
@mode contradiction check. parseJsDoc now ends prose at the first block
tag (standard JSDoc semantics), so the tags never change the rendered
catalog — only Source: line pointers moved.
Fills the ~139 gaps found across the 15 surface files, extends the spec
with negative-path fixtures for every new guard plus the exemptions,
records the decision as an implemented process RFC, and extends the
AGENTS.md typed-events bullet with the authoring rule. Runs inside
verify-cordis-catalog -> doc-sync, so CI and pre-push enforce it with
zero new wiring.
GenerateOptions.prefill had no production setter and both adapters
rejected it with LlmError('UNSUPPORTED') — its entire observable
behavior was two throws, each pinned by one adapter test. DeepSeek's
chat-prefix completion is a Beta feature on a base URL neither adapter
targets. ToolSchema.strict was threaded through defineTool, the
registry's schemas() allowlist, the deepseek wire mapping, a per-tool
payload-patching pass in the pi-ai adapter, and a tool-catalog render
row, yet no shipped tool set it and the internal endpoint story for
strict mode was never built.
Remove both fields end-to-end: the vocabulary in dsh-llm, the adapter
guards and wire branches, the dsh-tools threading, the tool-catalog
Strict row, the pinning tests, the core.md pastes, the adapter README
rows, and the cookbook line that used prefill as the UNSUPPORTED
example (now stated generically). The pi-ai payload fixup keeps the
half with a job: pi-ai stamps strict:false on every serialized tool,
so the fixup scrubs it unconditionally for wire parity with the
hand-rolled twin (per-tool set/delete machinery gone). temperature/
stop/maxTokens are untouched — honored end-to-end by both adapters.
Each knob returns with its first real producer: prefill with an
adapter that implements chat-prefix completion, strict with a tool
that wants it and a beta-endpoint story.
RFC: docs/rfc/implemented/simplification/2026-07-04-drop-inert-request-knobs.md
(moved from proposed/, amended to shipped reality); the content-block
vocabulary RFC's consequence line now records prefill as producer-gated.
dsh-llm owns the vocabulary (attribution.ts): AppIdentity with the version
read from the package manifest, userAgent(), and attributionHeaders(target,
identity) over a closed AttributionTarget union ('generic' | 'openrouter').
Both adapters send the headers on every provider request — llm-deepseek in
its fetch headers, llm-pi-ai through pi-ai's StreamOptions.headers — behind
an explicit attributionTarget config (never inferred from baseURL), with
mock-server tests asserting exact wire arrival and the absence of the
OpenRouter set by default.
The RFC moves to implemented/ amended with the settled identity (the
deepseek-harness token, the DeepSeek Harness title, the planned
deepseek-ai/deepseek-harness-sdk URL behind a FIXME until that repo exists)
and the explicit-config OpenRouter decision.
The vocabulary maps grow by declaration merging, and the admission policy
stated on TurnEndReasonMap is that a variant lands with its first emitter.
Three declared items had no producer and no consumer:
- CacheHint and the cache?: CacheHint fields on TextBlock/ToolResultBlock:
nothing constructs a block with cache:, and neither adapter reads .cache —
DeepSeek prompt caching is automatic (hints map OUT of responses, never IN).
- MessageSourceMap.agent: zero constructors; the subagent backends send the
parent prompt with no source (logs as user), and the envelope renderer
interpolates source.kind without routing on it.
- TurnTriggerMap.continuation: the loop structurally cannot emit it —
continuation is further steps within a turn, never a new turn — and its only
writer was an llm-replay test fixture that needed any non-message trigger
(now an injection trigger).
Each variant returns the day it gains a real producer, via the same
merge-extensible maps. Docs updated in the same change: the MessageSourceMap
paste in core.md, the TurnTriggerMap paste in session.md (manifest untouched —
both symbols survive), the content-block vocabulary RFC's cache-hints
consequence line, and the RFC moved to implemented/ and amended to shipped
reality (the image block's own cache field had already left with the
drop-image RFC).
examples/acp-agent/cordis.snapshot.yml is a 26-line declarative
overlay: one entry mounts @cordisjs/plugin-include on ./cordis.yml with
patches that disable the llm-deepseek entry by id and insert
llm-replay. Every other entry is the live tree loaded through the
include, so the replay tier exercises exactly what ships and an
app-shape change lands once — the silent-drift class the hand-mirrored
125-line twin invited is structurally gone. The bin is untouched;
recording still boots cordis.yml; assertEntriesLoaded tolerates the
disabled entry by design. All snapshot scenarios pass unchanged,
byte-identical goldens included; the include applies patches at load
time only, which a one-shot replay boot is exactly.
Implements docs/rfc/implemented/testing/2026-07-04-single-source-acp-replay-config.md
(moved from proposed/ and amended); the acp-snapshot-tests and
hook-snapshot-matrix RFCs' replay-config facts are amended in the same
change.
ImageBlock had no production producer and every consumer dropped it:
the deepseek serializer skipped it, the pi-ai converter skipped it as
unrepresentable, the ACP bridge neither advertises image prompt
capability nor forwards image blocks, and compact-basic charged a flat
85-token estimate and rendered an [image] placeholder. A block
constructed today would silently vanish from the wire — the vocabulary
advertised a capability no path honors, the silent-data-loss shape the
defensive patterns warn against. The only constructors were tests
pinning the skip/estimate branches.
Remove ImageBlock and its ContentBlockMap entry (its cache?: CacheHint
field leaves with it; CacheHint itself and the other two cache? fields
are out of scope). compact-basic loses its explicit image estimate and
placeholder arms (the merge-extensible default arms absorb the case);
the deepseek serializer, pi-ai converter, and ACP codec already handled
image in their default arms, so only their image-naming comments
change. The codec's inbound rejection of ACP-protocol image prompt
content stays — that guards wire content a client can send regardless
of our vocabulary.
Tests that constructed harness image blocks to pin the removed branches
are dropped (the 85-token estimate pin) or retargeted onto plugin-added
block types / other non-text blocks, which the surviving default arms
own. Docs, the type-equiv pastes, and the content-block vocabulary
RFC's block list and multimodal-home consequence are updated in the
same change; the RFC moves to implemented/ and the index is
regenerated. A real multimodal feature reintroduces image via
declaration merging together with the adapter mapping, ACP
advertisement, and compaction pricing that honor it.
The four near-twin helpers the two published bins carried — loadEnv,
installFailLoud, assertEntriesLoaded, boot — live once in
packages/ui/app-boot, parameterized by the bin's diagnostic prefix and
injectable at their side-effect seams (warn sink, process slice), so
every branch sits under the per-file 100% coverage gate: the unit suite
drives boot() in-process against the real Loader (relative-specifier
configs) through both the settled-tree path and the fiber-less-entry
rejection, and exercises the ENOENT/unloadable .env split, the
Error/non-Error/stackless fail-loud arms, and the disabled-entry
exclusion. resolveConfigPath (snapshot-aware) becomes the single path
resolver for both bins.
Each bin.ts is now a thin self-executing composition plus its
app-specific lifecycle (acp: replay env-skip + stdin-EOF dispose;
stdio: nothing extra), exports nothing, and stays coverage-excluded;
the built-bin smokes still prove both artifacts under plain node in the
node_modules-shaped temp dir (now symlinking ui/app-boot), including
the missing-config non-zero exit.
Implements docs/rfc/implemented/simplification/2026-07-04-share-app-bin-boot-glue.md
(moved from proposed/ and amended); the extract-example-app-packages
RFC's bin-ownership facts are amended in the same change.
Two pieces of dsh-acp surface were unreachable from any shipped config:
- AcpConfig.agentName/agentVersion: the app package hands the bridge only
{ model, systemPrompt }, so no leaf cordis.yml could set them; they were
settable only by direct-mounting the bridge (a unit test). Hardcode
agentInfo at the initialize site and delete the fields, their schema
defaults, the ?? fallbacks, and the TODO(double-default) whose subject
vanishes. The handshake wire value is unchanged (all snapshot initialize
lines byte-identical).
- The toolKindFor name heuristic special-cased bash*/read*/write/edit*
names in the generic-fallback path, violating the bridge's own design
rule ("the bridge never special-cases tool names"). Every first-party
tool ships its kind via presentCall; the fallback now renders the
neutral kind 'other'. The fallback is reachable when a presentCall
throws OR when model args fail the tool schema (defineTool's presentCall
wrapper returns undefined on violations) — the latter shows up in one
committed golden (hook-codex-posttool-block: three bash calls missing
the required description), whose kind cells flip execute->other. That
3-line golden refresh is the whole transcript delta.
The empty-arguments branch of parseToolArguments lost its only exercise
with the deleted heuristic test; it is live behavior (JSON.parse('')
throws, so the guard is what renders a zero-arg call as rawInput {}), so
it gets a dedicated pin instead of deletion.
RFC moved to docs/rfc/implemented/simplification/ and amended to shipped
reality: fallback reachability includes schema-invalid args, and the
golden churn is exactly the three kind cells (the original zero-churn
claim held only for the branding half).
Implement the tighten-hook-protocol-contract RFC (moved to implemented/):
- HookDialect narrows to 'claude' | 'codex': the 'native' variant had zero
producers (native plugins on the seams write no hook/* provenance), and the
dialect is defined as the bridge that ran the hook.
- HookOutput.suppressOutput is gone: the codec parsed it and every path
discarded it with no warn and no deferral — hook stdout never enters a
transcript, so there is nothing to suppress.
- hook/result.durationMs is gone: durable timing telemetry with no reader
that the snapshot normalizer had to scrub as replay noise. With no duration
to measure, runHook loses its injected now clock and the single-field
RunHookResult wrapper — it returns the HookOutput directly. The committed
hook fixtures had the field stripped mechanically (field-only diff); the
stdout goldens never carried it.
- The bridges' double-defaulted defaultTimeoutMs config knob is replaced by
one reference-default constant, DEFAULT_HOOK_TIMEOUT_MS, exported from the
lib's runner and applied inside runHook; per-hook timeoutSec stays the
override surface.
- The hook/result semantics move into the lib that declares the event:
HookResultRecord now carries the decoded HookOutput and appendHookResult
derives the decision string (decision ?? stop-on-continue:false ?? pass)
and the 500-char stderrSummary truncation; both bridges delete their
byte-identical private copies. The snapshot suite passes against the
existing goldens, proving the derived values are unchanged.
- Rider: BLOCKING_EXIT_CODE is codec-internal again (zero importers).
Amend the hook-protocol-lib and hook-snapshot-matrix RFCs to the new facts,
update the lib/bridge READMEs and the session.md event tables, and retarget
the affected unit tests (including new lib-level coverage of the derivation
rules).
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.
RFC: docs/rfc/implemented/simplification/2026-07-04-drop-unconsumed-web-observation-surface.md
The readline UI lives inside @deepseek-ai/dsh-stdio-agent as the
in-package stdio-chat module; the packages/support/ui-stdio package is
gone. The app's front-door cluster always includes this UI and nothing
else composes it, so the boundary bought manifest/tsconfig/module-graph/
README/publint surface for a helper that is not independently
swappable — and a product app no longer depends on a support package
documented as not-product-surface.
createStdioChat, the StdioRuntime test seam, and both unit suites moved
verbatim (imports rewired to the module path); the named
name/inject/Config/apply export shape stays, being the contract the
app's ctx.plugin mount consumes. Coverage stays per-file 100%; the
built-bin smoke under plain node and both keyless Loader-path smokes
prove the published artifact and the demos end-to-end.
Implements docs/rfc/implemented/simplification/2026-07-04-fold-stdio-ui-helper.md
(moved from proposed/ and amended to the shipped shape).
The fs seam split left four pieces of pre-split surface populated on
every call and read by nobody:
- STREAM_MIN_SIZE + FsIoInternals.streamMinSize in dsh-fs-local: the
backend has no read routing (readWholeText/streamWholeText are
separate primitives the caller picks), and the real 10 MiB routing
constant lives in dsh-tool-fs's read tool. Delete the dead mirror and
the knob whose JSDoc claimed an override that did not exist; the
remaining FsIoInternals knobs stay (the atomic-write tests use them).
- FsTarget.inputPath: a "diagnostics only" field every backend and test
fake had to fabricate, with zero production readers (policy and error
messages use targetKey/displayPath). listDir gave children the bare
entry name, which was nobody's input.
- FsEditOutcome.replacements/.replaceAll: replacements had no reader
(the single-match policy is enforced by the FS_AMBIGUOUS_EDIT /
FS_EDIT_NOT_FOUND throws, whose message keeps the internal count);
replaceAll only echoed the replace_all argument back to
formatEditOutput, which now takes it from the parsed args. The
outcome shrinks to { version, before, after }, parallel to
FsWriteOutcome's backend-discovered fields. Emitted text is unchanged
for both branches (no snapshot churn).
- FileReadOutcome.limit/.version: formatReadOutput renders
offset/lines/totalLines/truncatedByBytes only, and the fs/observed
emit uses info.version directly.
Backends shed four fabrication obligations and gain none. Doc pastes
(core-data-structures/filesystem.md), the dsh-fs README resolve row,
and the test fakes shrink with the types. RFC moved to
implemented/simplification and amended to the shipped shape
(FsEditSpec -> FsEditRequest name fix; manifest rows needed no change).
agent/steering was the last transient mirror of a durable session event:
drainSteering appended the durable steering/message {turn, content, source}
and emitted the identical fact one line later. Zero production listeners
existed — every steering consumer (hook bridges, goldens, deriveMessages)
reads the durable event — and the one regression test subscriber asserted
a fact the log already records.
Remove the declaration (dsh-agent types + JSDoc list + README row), the
emit in drainSteering (its ctx parameter goes too), and the emit line in
the loop-pseudocode blocks (loop.ts module doc, architecture.md); the
cordis catalog is regenerated. The regression test now pins source
preservation on the durable steering/message event. Live-notification
needs keep their surviving homes: agent/queued at enqueue time,
session/event at drain time.
RFC: docs/rfc/implemented/simplification/2026-07-04-remove-agent-steering-mirror.md
(moved from proposed/, amended to shipped reality). The three implemented
RFCs that stated the retention — the boundary-mirror removal, the
stream-chunk removal, and event-domain-semantics — are amended to point
at that RFC as the record of the removal, per implemented/AGENTS.md.
The rejected retire-mid-turn-steering RFC keeps its frozen text (it
records the declined proposal); the steering capability itself —
steer(), the durable event, continuation forcing — is untouched.
docs/rfc/README.md's per-lifecycle tables are now generated between
gen-rfc-index marker comments from each RFC's path (lifecycle/class),
H1 title (optional 'RFC: ' prefix stripped), and filename date, sorted
by date then filename — the one docs region every proposal wave edits
and every concurrent branch conflicts on becomes derived state.
scripts/rfc-index.ts owns the shared walker (closed lifecycle/class
sets, structure rules, parseable-H1 requirement) and the renderer;
gen-rfc-index.ts is the writer CLI; verify-rfc-classification.ts keeps
the structure check and asserts the committed regions byte-match a
fresh render (freshness subsumes the index-completeness check, since a
generated-from-disk table is definitionally complete and correctly
headed). A malformed H1 is a hard error in both directions, so the H1
is now load-bearing as the title source — the one nonconforming H1
(a status suffix duplicating the path) is normalized.
Implements docs/rfc/implemented/process/2026-07-04-generate-rfc-index-tables.md
(moved from proposed/ and amended to the shipped mechanics); the
classification RFC's verify-only stance carries the supersession
cross-link per implemented/AGENTS.md.
Applies the documentation standard to its biggest offender. Every rule
survives as one to three lines plus a link to its durable home; the
stories, duplicate statements, and re-narrations go:
- Situational clusters evict to new homes: docs/testing.md (tiers,
with-key policy, real-over-mock, world-verification, real-entry-path
guards), docs/defensive-patterns.md (the bug-class rules), and
docs/cookbook/responding-to-pr-review-on-a-stack.md (the stacked-PR
review procedure).
- Doc-authoring rules consolidate into docs/AGENTS.md § Writing rules
(current-state-never-history, md-wrap, ts-block compilation, @mode,
catalog same-change, pair same-change).
- packages/README.md drops to the group table + the extension-vs-bundle
dependency rule; the hand ASCII graph yields to the generated
module-graph.md; group READMEs are the canonical per-package map.
- packages/AGENTS.md keeps only its packages-specific rules (export
shape, ctx.get, real-Loader coverage); examples/AGENTS.md repoints
its with-key-policy link; rfc/README.md loses a narrated-history
aside; dsh-code-review / dsh-find-simplifications / verify-md-wrap
references follow the moved content.
- Budget manifest ratchets: AGENTS.md 8200 -> 1500 (now 1,495 words),
packages/README.md 1900 -> 600, packages/AGENTS.md 600 -> 450; the
two new eviction docs join the budget set (testing 800, defensive
550); docs/AGENTS.md raises 1000 -> 1250 for the absorbed writing
rules (the one justified increase). The doc-tiers RFC's deferred list
prunes the two items this change ships.
Maintainer decision: the subagent seam's deferred capability vocabulary
(outputSchema/structured, toolFilter, sendMessage/resume) is
intentionally reserved — the seam advertises the full intended contract
ahead of its implementations so providers and consumers grow into a
stable shape. Moved to rejected/ with the rationale on the status line;
the consumer-evidence analysis stays as the record of what is currently
unimplemented.
Standing docs accrete a paragraph per PR with nothing pushing back; the
root AGENTS.md reached 8,130 words in 50 commits with the same rule
stated two and three times. This encodes the counter-pressure:
- docs/AGENTS.md becomes the documentation standard: the tier taxonomy
(one home per fact), target word budgets, and the slop checklist.
- verify-doc-budgets joins doc-sync: word ceilings for the six
accretion-prone standing docs, manifest-driven, frozen at current
sizes and ratcheted down as each doc is brought to target.
- .agents/skills/dsh-doc-standards: the thin placement/audit/red-gate
workflow over the standard, mirroring the dsh-translate-docs split.
- RFC (implemented/process) records the decision, alternatives, and
the first audit cycle's deferred work list.
The gate's first catch was the standard itself (1,057 > 1,000); it
ships condensed to 984 words rather than with a raised ceiling.
Deduplicate the parallel sweep from codex/exhaustive-simplification-rfcs
(merged in the parent commit) against the twelve RFCs already here, on
the merits per item:
Ported (rewritten to this set's evidence standard):
- fold-stdio-ui-helper — verified: dsh-stdio-agent is the only runtime
importer; the fold resolves the documented product-app-depends-on-
support-package tension. The false acp-agent analogy is replaced with
the real distinction (protocol product surface vs one app's front-door
scaffolding).
- generate-rfc-index-tables — verified: the classification RFC records
rejecting generation; the index tables are the repo's only
systematically conflicting docs region. Process framing made timeless.
Consolidated into existing owners:
- web searchStatus()/fetchStatus()/WebCapabilityStatus (verified: zero
production callers; the tool-web README and architecture.md claims are
drift) → drop-web-providers-change-event, renamed
drop-unconsumed-web-observation-surface.
- hook/result.durationMs (unread, nondeterministic, normalizer-scrubbed)
and the double-defaulted defaultTimeoutMs knob →
tighten-hook-protocol-contract.
- the exercised-but-unadvertised exec.arguments mutation path (a
tool-bash integration shim rewrites through it) → a sanction-or-seal
note in the pre-tool-input-rewrite proposal.
- the dormant-guard critique of subagent depth machinery → recorded in
prune-unimplemented-subagent-vocabulary as the considered-and-rejected
alternative, with the keep sharpened (uncapped-today acknowledged;
wiring the cap is the completion, not deletion). getProvider()/list()
and lastAssistantMessage recorded as examined-and-kept (bash-revert
precedent; observe-enrich recorded keep).
Not ported (with reasons):
- tools/change + system-prompt/change removal — recorded keeps in the
adapter-change RFC, unengaged by the sweep; no new facts.
- LlmService.models() — flagged by both surveys, but two lines with a
plausible consumer: TODO-or-drive-by territory per the RFC bar, not
a proposal.
- SchemaProp.default RFC — already XXX(unused-default)-tagged; the RFC
bar excludes TODO-tracked provisional cleanups.
- PreToolDecision 'ask' removal — FIXME(permissions)-anchored deferral
with the permission system as its named consumer.
- Codex bridge Config.model, merged systemMessages — wire-faithful
tested surface / README-documented deferral.
Their in-code TODO notes (acp-test-harness, hook-snapshot-noise,
catalog-type-links) and the stale hook-prompt-block name fixes ride the
merge unchanged.
