Tianyi Cui 2489402610 Merge origin/master: scope-aware fusion of the tools/execute seam, session-prefix, and tool-cordis
Master brought 50 commits (the tool-cordis group, dsh-code-runtime + worker,
the tools/execute around-dispatch seam + timeout-policy, repeat-tool-guard,
agent/session-prefix, the ui reorganization). Beyond the ten textual
conflicts, the merge reconciles master's new seams with this branch's
scoped-registration world:

- tools/execute (new waterfall around core dispatch): dispatched with the
  SAME exec.agent carrier as the pre/post waterfalls — an agent.ctx wrapper
  times/retries only its own agent's calls — and its base thunk resolves the
  tool through the caller's visible view (get(exec.name, exec.agent)), so a
  scoped/shadowed tool dispatches and a restricted-away global stays
  UNKNOWN_TOOL. Declared this: Scoped<ToolRegistry> with the scope-filtered
  doc sentence; invariants table + verify-scoped-dispatch pin it (21 events).
- agent/session-prefix (new waterfall, once per loop instance): composed via
  the fused agentEvents dispatcher (scope-filtered like every agent-subject
  event), declared this: Scoped<Agent>, table-pinned. agent/pre-step keeps
  master's new sessionPrefix parameter with this branch's Scoped this.
- timeout-policy reads the budget through the caller's visible view
  (get(exec.name, exec.agent)): a scoped tool's own timeoutMs governs its
  calls; a global name-twin's budget is never misapplied to a shadowing
  per-agent variant.
- tool-cordis: cordis_inspect's tools section lists the CALLING agent's view
  (its description promises "what you can call"); the sandbox tool façade's
  reads resolve through the mount's own scope, mirroring where its register
  lands writes; sandboxRegisterTool's return type carries the exact-disposer
  union honestly. dsh-scope declared as peer+dev with the project reference.
- doc-sync chain unions master's verify-cordis-api with this branch's
  verify-scoped-dispatch; the generated catalogs, event matrix (the
  zero-dispatcher guard passes over master's new events), module graph, and
  the cordis api-catalog are regenerated on the merged surface.

Full gate sequence green on the merged tree: typecheck, lint, per-file 100%
coverage (2668 tests), snapshots (38), doc-sync, module graph, build,
hygiene, demo smoke.

timeout/ — tool-call timeout policy

The tool-call timeout policy plugin. A single product package: it is a deployment-policy consumer of the tools/execute around-dispatch seam (owned by dsh-tools) and the pure dsh-timeout library — not a swappable capability with an interface/implementation split, so it needs no seam trio.

Package Role ctx key
timeout-policy/ A tools/execute wrapper: for each configured tool it arms a per-call deadline on exec.signal and returns a structured TOOL_TIMEOUT result when that deadline wins (registers a tools/execute listener; injects nothing)

Timeout is split across three layers: dsh-timeout owns the pure timing/classification primitive (deadline/timeoutOf), each capability owns termination (bash kills its process group, the fetch provider tears down its socket), and this package owns the model-facing tool-call budget as deployment policy — no model-facing timeout argument, no global default. It is the middleware the timeout-library RFC foresaw. bash and hook command execution keep their own BASH_TIMEOUT backend timeout and do not route through this policy.
