Master arrivals re-grafted onto the plan-mode surfaces:
- Package invariant runtime contracts: every package owns ./invariant —
added the dsh-mode companion (mode/set payload validation: non-empty
trimmed name), its unit spec, exports/peer wiring, and the mode group in
the tsconfig invariant paths glob.
- Interception waterfalls gained an AbortSignal parameter
(agent/prompt-submit, agent/turn-continuation) and ToolExecutionInput.signal
became required: listeners and test dispatch updated; the exit tool now
forwards exec.signal unconditionally.
- TUI question dialog: master's position/unanswered header layout kept,
the plan-review detail block re-grafted between question and answers.
- LSP capability family arrived: lsp tool joins the catalog pin, dsh-lsp
examples deps beside dsh-mode; lsp-definition snapshot refreshed with
the mode command and modes advertisement.
- docs/architecture.md and packages/README.md regenerated tables re-grafted
(ctx.modes row, mode package row) and condensed within word ceilings.
- examples/acp-agent cordis.yml: kept the deployment-owned plan instructions
(incl. the conversational-agreement sentence) beside master's routed-model
compaction comment; snapshot expected outputs refreshed keyless and noise
fixtures restored.
Rename the six model-facing tools pty_* -> terminal_* and align every
description, guidance section, ACP card title, and rendered result to
terminal terminology. Package and service internals keep their technical
PTY names (PtyService, "unknown PTY session", node-pty).
Harden the local backend teardown:
- a failed close is retryable: drop the memoized rejection so a later
terminal_close re-runs against the live process table
- service disposal clears the backend, reservation, and owner-cleanup
registries even when a close fails
- stop readiness polling before teardown so an in-flight send settles as
session_exit instead of a mis-inferred wait reason
- bound the sanitizer's pending buffer against unterminated escape runs
Update the tool catalog, package READMEs, the bilingual Agent Note, and the
acp/headless pty-tools snapshots to match.
Name the runnable leaf for the line-oriented front door it owns, matching the existing tui-agent and acp-agent organization. Move the complete config, Code Mode overlay, tests, metadata, and generated composition graph together, then update every loader path and repository reference.
Keep the shared model identity independent of its terminal front door by phrasing the persona as a coding-agent role rather than retaining the retired leaf name. Regenerate graph and tool catalogs and re-record each affected bilingual pair so derived documentation cannot point at the removed path.
Implements the LSP capability seam RFC as three packages: dsh-lsp (the
ctx.lsp interface — provider registry by branded id + exclusive extension
mapping, per-query order-independent selection, closed request/result
vocabulary, LspError taxonomy), dsh-lsp-local (a generic stdio language-server
provider — Content-Length JSON-RPC framing, per-(provider, workspace) process
single-flight, transient didOpen/query/didClose, an abortable per-instance
queue, UTF-16 negotiation, host-namespace source reads outside ctx.fs, and
bounded shutdown/kill teardown), and dsh-tool-lsp (the model-facing lsp tool —
four operations, one-based UTF-16 cursor conversion, workspace-grouped location
rendering, hover capping, a required session workspace, and a timeout budget).
Why: an agent had text search and file reads but no way to identify a program
symbol — follow an alias, connect an interface to implementations, or read an
inferred type — before changing code. Splitting model contract, seam, and local
subprocess behavior keeps the four semantic queries stable across future remote
or sandbox-native providers without leaking a JSON-RPC escape hatch.
Semantic resolutions beyond line merges:
- The bash seam keeps resolveMode + the bash/resolve-mode waterfall on
master's task-free BashExecutor (run/start/resolve only; BashProcess
handles); tool-bash consults it at its stamping site and escalation
baseline on master's render/background split, with a waterfall test on
the recording executor.
- dsh-mode's BASH_FAMILY narrows to ['bash']: bash_output/bash_kill are
replaced by the kind-generic task_output/task_kill, which span every
task kind and only observe or stop work, so the access cap withholds
only the starter it can reason about.
- The plan-mode snapshot suite adopts master's pin grammar (tool-schema
sidecars; the expectedHeaderSnapshots extension is gone — the exit
transition deltas, and entering-before-turn-1 needs no second
snapshot); modes-advertise joins the plan header class (no-model, so
membership is vacuous). Fixtures re-recorded on the acp-demo bin;
the replay overlay gains the passthrough sandbox runner.
- examples/plan-acp-agent rewires to @deepseek-ai/dsh-acp-demo and drops
its tool-bash entry (the spine bundle now composes it); dsh-stdio (the
renamed stdio-chat home) keeps its /mode command and gains the dsh-mode
peer edge; the acp bridge keeps the modes surface beside master's
permission presets.
- mode README gains the Model Experience / Known Limitations sections the
new README gates require; AGENTS.md ceiling 1370 → 1440 for the kept
mode/ layout line and Agent efficiency section.
The background-task change repeated its lifecycle design across implemented RFCs, package READMEs, JSDoc, test commentary, and model-visible schemas. That repetition obscured the contracts that maintainers must preserve and added avoidable prompt tokens.
Rewrite the implemented RFCs around the current design, keep authorization, exact-owner cleanup, wait/abort ordering, producer quiescence, and teardown-failure guarantees at their owning surfaces, and remove peer surveys, review history, control-flow narration, and emphatic restatement.
Shorten the task and subagent schema wording, synchronize the bilingual tool cookbook, and regenerate the config, service, RFC, tool, and replay snapshot derivatives. Runtime behavior is unchanged; test edits update prose-only assertions and descriptions.
