Codex round-3: alias prose matches the gate's strength only when the
target's own contract is prose-only. An export-import alias to a
function, class, or namespace target (or an unresolvable one) is now
refused — those carry signature/member contracts the alias cannot
hold; export the declaration directly instead. Const/enum/interface/
type-alias targets keep the self-documentation contract.
Tests pin the refusal for function, class, and namespace targets;
module doc and RFC updated.
Review findings on the config catalog:
The transitive-paste closure deduplicated by bare name, so two DIFFERENT
package-local declarations sharing a name would silently collapse to the
first one pasted — and a reference satisfied by the wrong declaration is a
wrong catalog, not just a thin one. Every resolution is now identity-checked
by source pointer: reaching the same declaration again is benign, while a
name that resolves to two distinct declarations, to conflicting imports, or
to a declaration in one file and an import in another is a violation — a
verbatim fence has a single flat namespace, so the fix is a rename at the
source. A spec case pins the two-declarations collision.
docs/config-catalog.md also joins the translation-pairing exclusions: it is
a generated English-only doc, and without the entry the gate would accept a
hand-added .zh.md twin it must reject.
Codex round-2 review found three adjacent fail-open shapes:
- Wrapped function expressions escaped classification: parentheses,
as/satisfies casts, and non-null assertions are now peeled before the
arrow/function test (initializers and default exports), and a
single-call-signature type literal counts as the surface signature.
A literal mixing call/construct signatures with anything else is
refused outright — no single signature to hold the tags against.
- The blanket 'export import X = N.member' skip was unsound (the target
can be a non-exported namespace member no walk visits): an alias now
documents itself.
- The heritage extra-parameter duty missed binding-pattern extras,
which no base declaration can name: they now trigger the standard
binding-pattern violation.
Five new negative-path tests pin the closed shapes; module doc and RFC
updated.
Carved out of #170 per review feedback — the foundation the workflow tool
builds on, now standing alone on master:
- dsh-tools: the structured-output JSON Schema subset (StructuredOutputSchema,
assertSupportedOutputSchema, validateStructuredValue) — rejects loud outside
the enforced subset, listing every violation
- dsh-subagent: SubagentStartRequest.outputSchema / SubagentResult.structured
become a real capability; the service rejects a schema'd request whose
provider lacks it
- dsh-subagent-inprocess: the shared structured runtime — one global
structured_output capture tool, a prepend final-assembly listener that
strips the placeholder for plain agents and swaps in the run's own schema
(plus the calling instruction as a trailing section) for structured
children, an agent/turn-continuation veto once captured, and the
capture/nudge loop in the run driver (structuredNudgeRetries, cancellation
honored mid-nudge); lifetime refcounted by backends and live runs
- subagent-spawn / subagent-fork flip outputSchema: true
One deliberate divergence from the #170 revision: the backends do NOT add
'tools' to their plugin inject. Doing so deferred their apply past the todo
plugin, and the delegation tool mirrors provider lifecycle — so the
model-visible tool order of every existing prompt changed, invalidating every
recorded snapshot fixture. The runtime now gates its capture-tool registration
on tools availability itself (sync when live, a scoped inject fiber when the
Loader starts the backend first), keeping this PR byte-invisible to existing
transcripts: all 35 snapshot scenarios pass against master's fixtures
unchanged.
Codex round-1 review found three fail-open paths in the new gate:
- Unhandled export forms passed silently. checkDecl now fails CLOSED on
unrecognized exported statement kinds, 'export =' is refused outright,
'export import X = N.member' is an explicit documented skip (alias;
definition site owns the doc), and ambient 'declare namespace' bodies
recurse with implicit export semantics.
- Function-like exports escaped the function contract: non-identifier
default exports and consts with INLINE function-type annotations now
get full @param/@returns checks (the named-type waiver stays for
reference annotations only).
- The heritage exemption was name-only: it no longer exempts a public
override of a protected-only base member, and parameters the base
never names keep their @param duty (underscore-prefixed renames of a
base parameter count as the same parameter).
Eight new negative-path tests pin the closed gaps; RFC and module doc
updated to the refined contract.
Review findings on the config catalog:
The schema-subset check compared only top-level z.object keys against
top-level type members, so a nested loader-accepted key (agents[].id,
agentOptions.model, capabilities.*) missing from the declared type would
pass the gate unseen. The walk now collects nested object/array
compositions as key paths and resolves each against the declared config
type — through interfaces (heritage included), aliases, literals,
intersections, unions, arrays, indexed access, Partial-style wrappers, and
type references across package-local and workspace imports (re-export
chains included). The check stays presence-only and one-directional, and
only a definite miss is a violation: a path crossing a type the walk
cannot enumerate (an external package's) is skipped, never mis-reported.
The recursion guard applies at named declarations only — a structural
first child shares its span start with its parent, so a span-keyed guard
on every node mistakes ordinary descent for a cycle and silently turns
definite misses into unknowns.
The page and RFC framing also overstated the catalog as the exact
cordis.yml-settable surface: the paste is the plugin's full declared
config type, and a field the runtime schema deliberately excludes (the ACP
bridge's test-injected stream) is a runtime-only seam its own JSDoc marks.
Both now say so.
Five spec cases pin the new behavior: nested hidden key, workspace
intersection via star re-export, Partial wrapper, indexed-access
composition, and the external-type unknown path.
Master's reconstructable-requests overhaul (#179) meets the workflow tool:
- subagent-inprocess structured-output nudge becomes a system-prompt section
plus logged context (the injected-request waterfall shape is gone upstream)
- snapshot fixtures re-recorded on the merged tree so every request/header
carries the workflow tool; authored error-finish/cancel headers patched to
the merged tool list and system text
- architecture.md condensed back under its word ceiling; module graph regenerated
A directory holding exactly one file adds a path level for nothing;
cordis-catalog/ keeps its folder because it holds two sibling pages
(events.md + services.md), matching config-catalog.md which was born flat.
docs/tool-catalog/tools.md -> docs/tool-catalog.md and
docs/persistence-catalog/log-events.md -> docs/persistence-catalog.md; their
generators' OUT paths and in-page relative links drop one directory level,
and every citation repo-wide (docs, RFCs, package READMEs, generator
headers) is updated. graph-atlas.md, config-catalog.md, and the doc graphs
regenerate with the new paths.
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.
RFC: docs/rfc/implemented/process/2026-07-06-export-surface-jsdoc-gate.md
scripts/gen-config-catalog.ts walks every packages/<group>/<pkg> entry with
the TypeScript compiler API and emits docs/config-catalog.md: per loadable
plugin, the verbatim config declaration (JSDoc included) its apply/constructor
receives in a ts config-catalog fence, the inject requirements, resolved links
for every referenced type (package-local types pasted transitively, other
plugins' config types as intra-page anchors, LINK_MAP names to
core-data-structures, workspace types to source), and terse classification
lists for config-free plugins, abstract seams, and libraries — classification
is total, so a new package cannot go undocumented.
The walk enforces per-field JSDoc prose on every pasted declaration and
statically cross-checks the schemastery schema (z.object keys, z.intersect
composition across packages): every schema-validated key must be a declared
member of the config type. One violation existed repo-wide — the agents[].id
field in dsh-agent-loop — fixed by adding its JSDoc (which shifts the
cordis-catalog services page's source pointers; regenerated).
verify-config-catalog (--check) joins doc-sync; doc-typecheck learns the
ts config-catalog fence; gen-cordis-catalog exports its JSDoc/pointer helpers
and LINK_MAP for reuse. Negative-path spec in
packages/core/agent-core/tests/gen-config-catalog.spec.ts mirrors the
gen-cordis-catalog spec. Decision record:
docs/rfc/implemented/process/2026-07-06-generated-config-catalog.md (includes
the deliberate acceptance of README ## Config overlap).
Codex diff review, round 1, two (A) findings:
- The agent/request fallback resolved the RAW seed object — on later
steps the session's cached header fold — so a delegating listener
(await next(), mutate, return) could rewrite the fold in place and
the change would compare as already-baseline: no delta logged, the
persisted log unable to reconstruct the request (the dev invariant
would fire on the divergence, but the log would still lie). One
structuredClone'd, deep-frozen seed now serves both the listener
chain and the fallback — in-place shaping after delegation throws —
and Session.requestHeader() freezes its fold on update, so the leak
class is unrepresentable from either side. Pinned by a loop-level
delegating-mutator test.
- Doc sweep for the old contract: agent README's event row (mutate
GenerateOptions / tool filtering → frozen config seed, replacement
out, logged header), compact-basic's module JSDoc (summarize routed
through agent/request → direct one-shot at llm/stream), and
architecture.md's event-domain line (request mutation → call-config
shaping).
surface.replaceGeneration gets its direct-access test (the getter folds
a pending delta itself, not only via a nodes read); the reconstruction
theorem drives maxTokens and stop through the config waterfall; the
compact-basic envelope drops a dead conditional — config.maxTokens is
required and validated positive, so this backend's envelope always
carries the cap (the return type's optionality exists for overriding
subclasses).
Beyond the mechanical conflicts (provider capability lines vs master's new
inheritsParentContext field; generated catalogs regenerated rather than
hand-merged; knip/lockfile), three master-side reworks required semantic
adaptation of this branch:
- The persona rework removed AgentOptions.systemPrompt, which was the
structured-output instruction's channel. The instruction now rides the
SAME final-request enforcement listener that injects the schema'd tool:
appended per request to final.system (per-request wire state, not agent
prompt state). Tests assert the wire request (adapter.requests) instead
of child.options; the bare-direct-dispatch test pins the no-system arm.
- Tool guidance moved out of deployment prompts into per-tool prompt
sections; the examples' workflow paragraph became a tool:<toolName>
section contributed by dsh-tool-workflow (explicit-ask-only policy),
and both example personas resolve to master's minimal identity+behavior
form. tool-workflow gains inject: systemPrompt (+ peer dep, tsconfig
ref); the export-shape guard updated.
- The uniform-RFC-format gate: the dynamic-workflows RFC restructured to
the implemented/ skeleton (bare Status line; Proposal -> Decision;
What-was-rejected -> Alternatives considered; new Consequences), and
the overall-run-timeout deferral is now recorded in the RFC's Deferred
list. The doc-graphs atlas classification gains the workflows seam
(workflow-vm implementation, tool-workflow consumer).
Master's harness-identity section made "empty assembled prompt" states
unreachable through the loop, so the instruction-append is a plain
undefined-ternary and the structured tests assert append-not-replace.
All snapshot goldens (including workflow-run) replay unchanged. Full
local CI-equivalent gate sequence green on the merged tree.
The loop is now transmission-stateless; a request is a pure function of
(session log, this step's rendered assembly, current AgentOptions):
- The reconstruction boundary is step/start: the messages snapshot is
taken in the same synchronous frame immediately before the step/start
append, so the request's messages are exactly the derivation over
events[0..stepStartSeq) — an inject() from an agent/request listener
(or any concurrent task) lands after the boundary and joins the NEXT
request. This changes behavior for a synchronous step/start
session/event listener that appends content (master derived after the
append, so such a listener could reach the current request):
agent/pre-step is the sanctioned seam for current-request content.
- agent/request is re-typed to config-only: (agent, turn, step,
config: LlmCallConfig, next) → LlmCallConfig. The frozen seed comes
from AgentOptions on a loop instance's first request (explicit options
beat the logged baseline — fork overrides and resume reconfiguration
stay correct) and from the log's folded header afterwards; listeners
return a replacement to switch. Content shaping through the request is
no longer expressible — model-visible content flows through the log
channels.
- recordRequestHeader appends whatever header event the request owes the
log before dispatch: an 'initial'/'resume' snapshot anchoring each
loop instance, a round-trip-verified delta on change, a 'fallback'
snapshot when the encoding cannot express it. Session.requestHeader()
is the log's incrementally-folded baseline.
- Requests are deep-frozen before dispatch (deepFreeze exempts the
AbortSignal — freezing one breaks AbortController.abort() outright);
frozen + sessionId is the loop-built marker the dev invariant keys on.
Ported from #162 and re-anchored on the log: the append-extension /
frozen-end-to-end / compaction-resend / prompt-change property tests,
plus new specs for the boundary semantics, resume anchoring, and the
end-to-end theorem (every recorded request rebuilds byte-equal from the
log alone). Live cache-hit e2e (request-cache.e2e.ts) verified against
the real DeepSeek API. Snapshot goldens intentionally stale until the
single re-record after the compact/summary envelope lands.
deriveMessages() no longer re-derives and re-clones the whole surface
per call: each node is projected exactly once, when first seen (O(new
nodes) per access), through the now-public deriveEventMessage — the
per-node pure function external reconstructors and the dev invariant
fold over a log prefix, so no two paths can disagree about a request's
messages. A surface rewrite (replace, invalidate) rebuilds, signalled
by SurfaceManager.replaceGeneration — monotonic, bumped by every folded
replace and by invalidate(), never reset. Callers get a fresh array
snapshot per call over SHARED deep-frozen messages: isolation of the
append-only log moves from per-call cloning to unrepresentability
(mutation throws), which the two isolation tests now pin directly.
Every conversation request's non-content half (system prompt, tool
schemas, call config — the EpochHeader) is now recorded in the session
log: a 'request/header' full snapshot (reason 'initial' | 'resume' |
'fallback') anchors the fold at conversation birth and process
boundaries, and 'request/header-delta' events (system line-trim,
name-keyed tools delta, whole config) encode mid-run changes. The pure
trio — foldRequestHeader / diffHeader / applyHeaderDelta — reconstructs
the header any request was built under from the log alone; the writer
contract round-trip-verifies every delta with a 'fallback' snapshot
when the encoding cannot express a change (pure tool reordering), so a
well-formed log always folds cleanly. Canonical absence: empty system
and empty tools normalize to absent fields, matching request builds.
Persistence and cordis catalogs regenerated; SessionEventMap paste and
EpochHeader added to the core-data-structures session page.
ds-review-bot round 2, both warnings:
- subagent/provider-removed now routes through emitLifecycle (per-listener
containment, the subagent/start|end precedent) instead of raw ctx.emit,
whose dispatch halts on the first throw: a throwing subscriber can no
longer starve a later mirror into keeping a stale tool, nor disrupt the
backend fiber's teardown mid-disposer. provider-added deliberately keeps
propagation (register-time rollback semantics, like the system-prompt
registries); the asymmetry is documented on emitLifecycle, the event
JSDoc, and the provider-lifecycle RFC.
- The documented model-via-agent/request fallback composes with a
{{model}} persona via the ownership rule itself: the plugin supplying
the model late states it early on the system-prompt/assemble waterfall.
Declined re-ordering render after agent/request — it would break the
agent/pre-step contract (compaction must measure the prompt the model
sees). New loop test pins the supply path end-to-end; the RFC's
{{model}} consequence bullet now covers supply as well as switch.
Review round 2 (tianyicui inline comments):
- dsh-system-prompt itself registers the harness:identity (-100) and
deployment:persona (0) sections — they must survive a swapped loop
plugin, so they leave dsh-agent-loop; the persona text is the plugin's
own validated 'persona' config. The model/cwd variables STAY on the
loop: runtime facts of the agents it drives.
- AgentOptions.systemPrompt is deleted with all its forwarding plumbing:
the app configs' systemPrompt keys become 'persona' routed through
dsh-agent-core (schema = z.intersect of the owners'), the ACP bridge
and tool-subagent stop carrying persona configuration, and subagent
children now render the deployment persona like every other agent.
- Example personas drop transport/interface trivia (ACP, CLI) — facts
irrelevant to the model.
- Root CONTEXT.md removed (not idiomatic); its persona definition was
wrong under the new ownership anyway.
- Docs, READMEs, the prompt-variables RFC, and generated catalogs
updated; new loop test pins the assemble-waterfall escape valve
(an emptied assembly sends NO system field).
Reconciliations beyond textual conflicts:
- product rename (DeepSeek Code -> DeepSeek Harness SDK) applied to the
PR-added assertion in system-prompt.spec.ts that master's rename
commit could not reach
- architecture.md: master's rewrite kept; this PR's prompt-assembly
semantics re-added in the new doc's voice (Turn Flow footnote +
service-spine row), within the 1630-word ceiling
- cordis catalog regenerated into master's split events.md/services.md
(events-and-services.md deleted); module graph and doc graphs
regenerated to pick up this PR's new events and dependency edges
