fix(engine,shell): harness fixes from the DeepSeek/DSH parity comparison

On 2026-10-17 Codewhale and DeepSeek's own harness, DSH 0.2.1-rc.2, were compared on deepseek-flash (DeepSeek-V4.1-Flash-1017). The comparison covered wire format, multi-turn state, cache, prompt and tool surface, and mined 185 exec runs and 310 local sessions. A skeptic re-checked every finding. A blind patch A/B scored Codewhale's edit mode 5/5, DSH 3/5 and read-only JSON patches 2/5. Evidence is in CW/artifacts/deepseek-harness-parity-20261017/. This commit fixes the contained defects; CW-7450 tracks the rest. - zsh: the tool named bash runs $SHELL, and zsh's NOMATCH and EQUALS options broke Bash idioms the model writes, such as grep --include=*.rs and [ "$a" == "$b" ]. That caused 334 failures in 196 of 310 sessions, and in exec runs 175 greps never ran. ShellDispatcher::build_command_parts now starts zsh with +o nomatch +o equals (ShellKind::is_zsh), and ZSH_GUIDANCE says so. Display still uses the requested command. The same dispatcher runs user ! commands. - task_shell_wait is now in DEFAULT_ACTIVE_NATIVE_TOOLS. bash and its backgrounded results tell the model to call it directly and not to sleep-poll. Before, every long job cost a tool_search round trip plus a change:tool_surface re-pin (188 tool_search calls, 208 "sleep N" commands). KV-cache effect: the frozen prefix grows by one small tool schema, and the mid-session re-pin goes away. TOOL_SURFACE.md (en and zh_hans), MODES.md, public-surface-facts.json, web tools copy, the conformance goldens and the tests that pin the default list are updated. - exec_stream_final_answer_text skips runtime-owned user messages (runtime_handoff::is_runtime_owned_user_message) when locating the turn start. A background-shell completion appended after the answer no longer makes the receipt report an empty final answer, which happened in 52 of 185 runs; fleet then recorded no answer. - The engine's local stop_reason_is_output_limit is deleted, and continuation.rs now uses codewhale_models::is_output_limit_stop_reason, which strips the incomplete: prefix that the Responses parser adds. A reasoning-only output-limit stop on deepseek-flash is no longer re-sent up to two more times, and it now reports the output-limit message. The three extra spellings the local helper knew (model_length, output_limit, max_completion_tokens) move into the shared helper. The misplaced should_fail_no_sendable_content doc comment goes back on its function. - tool_choice "none" now reaches the provider. The Responses builder forwards none and keeps sending auto for every other choice, and the DeepSeek Chat path keeps none while thinking is on; required and named choices are still dropped there because DeepSeek returns a 400 for them. The compaction known-limit comment is updated to match. - is_incomplete_stop_reason treats insufficient_system_resource and aborted, DeepSeek Chat's interrupted-generation finish reasons, as incomplete. Every item except the zsh change was drafted by Codewhale running DeepSeek-V4.1-Flash-1017 in scratch exports. Claude reviewed each diff and corrected two of them: the stop spellings the shared helper lacked, and the stale compaction comment. Gates for this batch (source 0d906da665 plus the six commits of this push, before rebasing onto 20234af6d6): - cargo fmt --all --check: clean. - check-blocking-calls-budget: 539 sites, within budget. - codewhale-models lib: 40 passed. - codewhale-config lib: 800 passed, 1 skipped. - codewhale-cli lib: 501 passed, 0 failed. - codewhale-tui lib: 15,326 run, 15,320 passed, 6 failed. - Three failures were expected from the tool-text change. The conformance goldens were re-recorded (CODEWHALE_CONFORMANCE_UPDATE=1) and the zsh guidance assertion updated; conformance plus that test then passed 34/34. - Three are tools::test_runner tests that fail on this host only: the nested cargo inherits dev-cache CARGO_BUILD_BUILD_DIR and gets "Operation not permitted". Not touched here. - CI-form clippy -p codewhale-models -p codewhale-cli -p codewhale-tui -p codewhale-config --all-targets --all-features -D warnings: clean, after one needless_question_mark fix in runtime_api.rs. - check-facts OK; check-versions OK.

Saved settings\nstill normalize to the internal value `agent`.\n\n### Tool availability by mode\n\n| Tool family | Plan | Work | Operate |\n|:---|:---:|:---:|:---:|\n| `read` and policy-allowed deferred research tools | yes | yes | yes |\n| `write` and `edit` | visible names; execution denied | approval- and policy-gated | same as Work |\n| `bash` | visible name; execution denied | approval- and policy-gated | same as Work; delegation is preferred when parallelism or isolation helps |\n| `agent` | yes, subject to child-depth authority | yes, subject to child-depth authority | yes, subject to child-depth authority |\n| Deferred native, MCP, and plugin tools | discoverable through `tool_search` when policy permits | same | same |\n| Paid or external-service tools | follows permission posture | follows permission posture | follows permission posture |\n| Access outside the workspace root | explicit trusted paths only | only through trusted paths or trust mode | same trusted-path/trust policy as Work; fleet profiles never widen it |\n\nOperate changes scheduling emphasis, not authority. It neither adds a\nmode-specific tool denial nor bypasses the active approval, sandbox, shell,\nask-rule, repository-law, or managed-policy boundary. Plan remains the\nmode-specific execution boundary for shell and write-capable tools; that\nauthority difference does not require a different primitive vocabulary.\n\n### Operate loop (one screen)\n\n```text\nUser Line truncated

The v0.9.1\ncutover that produced it is recorded in `docs/RUNTIME_SIMPLIFICATION_DESIGN.md`;\nread the workspace version from `Cargo.toml`, not from this line. The registry\nremains larger than the first-turn catalog so\nsaved transcripts can replay and uncommon capabilities can be loaded on demand.\nThe model should learn one canonical name for each common operation.\n\nImplementation sources:\n\n- `crates/tui/src/core/engine/tool_catalog.rs` owns the eager/deferred catalog.\n- `crates/tui/src/tools/registry.rs` registers canonical tools and hidden aliases.\n- `crates/tui/src/tools/{file,file_tool,shell}.rs` own the small foreground\n  primitive behavior and schemas; the other native tools remain searchable.\n- `docs/RUNTIME_SIMPLIFICATION_DESIGN.md` records the v0.9.1 cutover and receipt.\n\n## Default-active contract\n\nNew turns start with twelve eager native names plus synthetic `tool_search`:\n\n1. `read`\n2. `write`\n3. `edit`\n4. `file_search`\n5. `bash`\n6. `agent`\n7. `workflow`\n8. `todo_write`\n9. `create_goal`\n10. `get_goal`\n11. `update_goal`\n12. `load_skill`\n13. `tool_search` (synthetic, always active)\n\nThe twelve native names are `DEFAULT_ACTIVE_NATIVE_TOOLS` in\n`crates/tui/src/core/engine/tool_catalog.rs`, pinned by\n`default_active_contract_keeps_discovery_and_core_tools_eager`. An authority\nboundary may remove `agent` at the maximum child depth, but route size alone\nmust not change this core vocabulary.\n\nThe direct schemas deliberately stay small:\n\n| Tool | Input | Purpose |\n|---|---|---|\n| `read` | `path`, optional `offset`, optional `limit` | Read a bounded file window with explicit continuation or truncation notices. |\n| `write` | `path`, `content` | Create or replace a file. |\n| `edit` | `path`, `edits` | Apply one or more unambiguous text replacements against one original snapshot. |\n| `file_search` | `query`, optional `path`, `limit`, `extensions`, `exclude` | Find files by name, path fragment or glob and return bounded, ranked matches. Respects ignore files; `exclude` replaces default exclusions. |\n| `bash` | `command`, optional `timeout`, optional `description` | Run one cancellable foreground shell command and return a bounded tail. The optional description is display-only. |\n| `agent` | delegated task and optional scope/context controls | Start or inspect focused child work. |\n| `workflow` | plan/script/source_path plus run controls | Coordinate multi-agent phases with dependencies and completion checks. |\n| `todo_write` | complete replacement list of `{content, status}` items | Keep optional, agent-owned progress notes for genuinely multi-step work. |\n| `create_goal` | objective plus optional budget | Start the session goal the turn works toward. |\n| `get_goal` | none | Read the active goal and its progress. |\n| `update_goal` | terminal status | Mark the goal complete or blocked. |\n| `load_skill` | optional `name`, `query` | Load a named skill's `SKILL.md` body and companion-file list; omit `name` or use `name=\"list\"` to list eligible skills, or use `query` to search names and descriptions. |\n| `tool_search` | `query`, optional matching controls | Discover policy-allowed deferred tools and add selected schemas to this conversation's toolbox. |\n\nMode is an authority decision, not a synonym system. Plan, Work, and Operate\nuse the same primitive identities. Plan centrally refuses `write`, `edit`, and\n`bash`; Work and Operate still pass those calls through approval, sandbox,\ntrusted-path, repository-law, and managed-policy gates. Full Access changes\nordinary approval behavior but does not bypass hard safety or repository law.\n\n`update_plan` remains registered only for saved-artifact compatibility and is\nnot model-visible. `tasks`, `Git`, `Run`, `Web`, `remember`, and other\nspecialized capabilities are searchable rather than first-turn ceremony.\n\nA Bash description appears as a muted, bounded note under the command on the\nTUI shell card, including on automatic runs. It never replaces the command and\nis excluded from execution, exact approval keys and Auto-Review input. The\noriginal description remains in the recorded tool input and exports. Approval\nprompts, `/jobs`, the activity inspector, ACP and other Runtime clients keep\nshowing the command; this change adds no description row to those surfaces.\n\n## Local code execution\n\n`code_execution` (Python) and `js_execution` (Node.js) use the same\npermission-aware local launcher as workspace task gates and test runs. Ordinary\napproval retains the effective session policy.

The v0.9.1\ncutover that produced it is recorded in `docs/RUNTIME_SIMPLIFICATION_DESIGN.md`;\nread the workspace version from `Cargo.toml`, not from this line. The registry\nremains larger than the first-turn catalog so\nsaved transcripts can replay and uncommon capabilities can be loaded on demand.\nThe model should learn one canonical name for each common operation.\n\nImplementation sources:\n\n- `crates/tui/src/core/engine/tool_catalog.rs` owns the eager/deferred catalog.\n- `crates/tui/src/tools/registry.rs` registers canonical tools and hidden aliases.\n- `crates/tui/src/tools/{file,file_tool,shell}.rs` own the small foreground\n  primitive behavior and schemas; the other native tools remain searchable.\n- `docs/RUNTIME_SIMPLIFICATION_DESIGN.md` records the v0.9.1 cutover and receipt.\n\n## Default-active contract\n\nNew turns start with thirteen eager native names plus synthetic `tool_search`:\n\n1. `read`\n2. `write`\n3. `edit`\n4. `file_search`\n5. `bash`\n6. `agent`\n7. `workflow`\n8. `todo_write`\n9. `create_goal`\n10. `get_goal`\n11. `update_goal`\n12. `task_shell_wait`\n13. `load_skill`\n14. `tool_search` (synthetic, always active)\n\nThe thirteen native names are `DEFAULT_ACTIVE_NATIVE_TOOLS` in\n`crates/tui/src/core/engine/tool_catalog.rs`, pinned by\n`default_active_contract_keeps_discovery_and_core_tools_eager`. An authority\nboundary may remove `agent` at the maximum child depth, and Plan registers only\nthe foreground shell surface (so no `task_shell_wait`), but route size alone\nmust not change this core vocabulary.\n\nThe direct schemas deliberately stay small:\n\n| Tool | Input | Purpose |\n|---|---|---|\n| `read` | `path`, optional `offset`, optional `limit` | Read a bounded file window with explicit continuation or truncation notices. |\n| `write` | `path`, `content` | Create or replace a file. |\n| `edit` | `path`, `edits` | Apply one or more unambiguous text replacements against one original snapshot. |\n| `file_search` | `query`, optional `path`, `limit`, `extensions`, `exclude` | Find files by name, path fragment or glob and return bounded, ranked matches. Respects ignore files; `exclude` replaces default exclusions. |\n| `bash` | `command`, optional `timeout`, optional `description` | Run one cancellable foreground shell command and return a bounded tail. The optional description is display-only. |\n| `agent` | delegated task and optional scope/context controls | Start or inspect focused child work. |\n| `workflow` | plan/script/source_path plus run controls | Coordinate multi-agent phases with dependencies and completion checks. |\n| `todo_write` | complete replacement list of `{content, status}` items | Keep optional, agent-owned progress notes for genuinely multi-step work. |\n| `create_goal` | objective plus optional budget | Start the session goal the turn works toward. |\n| `get_goal` | none | Read the active goal and its progress. |\n| `update_goal` | terminal status | Mark the goal complete or blocked. |\n| `task_shell_wait` | `task_id`, optional `wait`, `timeout_ms`, `cancel`, `gate` | Poll or stop a background shell task. Completion still arrives as a runtime event, so use it for early output, true barriers, or gate evidence. |\n| `load_skill` | optional `name`, `query` | Load a named skill's `SKILL.md` body and companion-file list; omit `name` or use `name=\"list\"` to list eligible skills, or use `query` to search names and descriptions. |\n| `tool_search` | `query`, optional matching controls | Discover policy-allowed deferred tools and add selected schemas to this conversation's toolbox. |\n\nMode is an authority decision, not a synonym system. Plan, Work, and Operate\nuse the same primitive identities. Plan centrally refuses `write`, `edit`, and\n`bash`; Work and Operate still pass those calls through approval, sandbox,\ntrusted-path, repository-law, and managed-policy gates. Full Access changes\nordinary approval behavior but does not bypass hard safety or repository law.\n\n`update_plan` remains registered only for saved-artifact compatibility and is\nnot model-visible. `tasks`, `Git`, `Run`, `Web`, `remember`, and other\nspecialized capabilities are searchable rather than first-turn ceremony.\n\nA Bash description appears as a muted, bounded note under the command on the\nTUI shell card, including on automatic runs. It never replaces the command and\nis excluded from execution, exact approval keys and Auto-Review input. The\noriginal description remains in the recorded tool input and exports. Approval\nprompts, `/jobs`, the activity inspector, ACP and other Runtime clients keep\nshowing the command; this change adds no description row to those surfaces.\n\n## Local code execution\n\n`code_execution` (Python) and `js_execution` (Node.js) use the same\npermission-aware local launcLine truncated
