It owns request handling, turn classification, tool dispatch, approval suspension, answer admission, deterministic terminal answers, anchor state, project snapshot caching, and conversation trimming. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/conversation.rs`, `src/runtime/types.rs`. +- The backend does not execute tools or decide whether a response is valid. `ModelBackend::generate()` only receives a `GenerateRequest` and emits `BackendEvent`s; the runtime parses the returned text, discards invalid protocol, and decides whether to keep or replace the assistant output. Code: `src/llm/backend.rs`, `src/runtime/orchestration/generation.rs`, `src/runtime/protocol/tool_codec/`, `src/runtime/orchestration/engine.rs`. +- The runtime injects turn-local policy before every generation. `run_generate_turn()` appends a system message naming the active `ToolSurface`, and may append a bounded project snapshot hint. These hints are request-local and are not persisted in `Conversation`. Code: `src/runtime/orchestration/generation.rs`, `src/runtime/investigation/tool_surface.rs`, `src/runtime/project/project_snapshot.rs`, `src/runtime/protocol/prompt.rs`. +- The runtime, not the backend, chooses when tools are available. `select_tool_surface()` selects one of `RetrievalFirst`, `GitReadOnly`, `AnswerOnly`, or `MutationEnabled`. `tool_allowed_for_surface()` enforces surface membership before dispatch. Code: `src/runtime/investigation/tool_surface.rs`. +- The runtime guarantees project confinement. All tool inputs are converted from raw `ToolInput` into `ResolvedToolInput` before dispatch; read, list, and search scopes must stay inside `ProjectRoot`; mutation targets also reject symlink parents and symlink targets. On Windows, `ProjectRoot::new()` strips the `\\?\` UNC prefix after `fs::canonicalize`. Code: `src/runtime/project/resolved_input.rs`, `src/runtime/project/resolver.rs`, `src/runtime/project/project_root.rs`. +- The runtime guarantees that mutations do not execute during the proposal phase. `edit_file` and `write_file` and `shell` return `ToolRunResult::Approval(PendingAction)` from `run()`, and only `execute_approved()` performs the actual action. Code: `src/tools/mod.rs`, `src/tools/types.rs`, `src/tools/edit_file.rs`, `src/tools/write_file.rs`, `src/tools/shell.rs`. +- The runtime guarantees that investigation answers are grounded in read evidence, not search text alone. Search-only answers, unread file citations, out-of-scope citations, repeated tool drift after evidence, and repeated malformed protocol all terminate through runtime-owned branches. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/tool_round.rs`, `src/runtime/investigation/investigation.rs`, `src/runtime/protocol/response_text.rs`. +- The runtime guarantees bounded context growth. Tool results are capped through `cap_tool_result_blocks()` (driven by `ContextPolicy` derived from `BackendCapabilities.context_window_tokens`), old tool exchanges are live-trimmed without removing conversational messages, context usage is estimated, `/context stats` reports live usage, `/compact` prunes stale tool results, a warning fires at 75%, and auto-prune runs at 90%. Summarization is deferred. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/context_cap.rs`, `src/runtime/orchestration/context_policy.rs`, `src/runtime/orchestration/command_handlers.rs`, `src/runtime/conversation.rs`. + +## Core Runtime Loop + +- `Runtime::handle()` is the single request entrypoint. It dispatches `Submit`, `Reset`, `Approve`, `Reject`, `QueryLast`, `QueryAnchors`, `QueryHistory`, `ReadFile`, `SearchCode`, `Undo`, `ProvidersList`, `ProvidersUse`, `GitBranch`, `GitStatus`, `GitDiff`, `GitLog`, `ListDir`, `LspStatus`, `IndexBuild`, `IndexStatus`, `ContextStats`, and `Compact` requests. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/types.rs`. +- Slash-command requests (`GitBranch`, `GitStatus`, `GitDiff`, `GitLog`, `ReadFile`, `SearchCode`, `ListDir`) are dispatched through the `CommandTool` allowlist in `command_handlers.rs`. Mutating tools are excluded from this allowlist by construction. Code: `src/runtime/orchestration/command_handlers.rs`. +- `handle_submit()` rejects empty prompts and new submits while a `PendingAction` exists. It also special-cases exact anchor prompts and routes them into `run_last_read_file_anchor()` or `run_last_search_anchor()` instead of the normal turn loop. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/anchor_resolution.rs`, `src/runtime/investigation/anchors.rs`. +- A normal submit enters `run_turns_with_initial_reads()`. That function computes turn state once from the original user prompt: retrieval intent, direct-read mode, whether investigation is required, whether mutation is allowed, the `ToolSurface`, the `InvestigationMode`, and an optional prompt-derived path scope. State is collected into `TurnContext` and `TurnState`. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/turn_state.rs`, `src/runtime/investigation/prompt_analysis.rs`, `src/runtime/investigation/investigation.rs`, `src/runtime/investigation/tool_surface.rs`. +- Before any backend generation, the runtime may seed the first tool call itself. This happens for narrow natural-language edits (`requested_simple_edit()`), direct reads, directory listings, and permitted shell commands. The seeded call is stored as `PendingRuntimeCall { seeded_pre_generation: true }`, so the first tool can run with no backend round. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/turn_state.rs`, `src/runtime/investigation/prompt_analysis.rs`. +- Each loop iteration chooses an `effective_surface`. If `answer_phase` (`AnswerPhaseKind::PostRead` or `InvestigationEvidenceReady`) is active, `effective_surface` is forced to `AnswerOnly`; otherwise it uses the prompt-selected surface. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/turn_state.rs`, `src/runtime/investigation/tool_surface.rs`. +- `run_generate_turn()` builds the request from `Conversation::snapshot()`, appends the surface hint, optionally appends the project snapshot hint, sends the request to the backend, buffers streamed text, and only writes the assistant reply into `Conversation` after a complete response is available. Code: `src/runtime/orchestration/generation.rs`. +- After generation, the runtime parses the assistant text with `tool_codec::parse_all_tool_inputs()`. If no tool calls are parsed, the runtime either admits the answer or replaces it through guard branches. Code: `src/runtime/protocol/tool_codec/tool_parser.rs`, `src/runtime/orchestration/engine.rs`. +- If tool calls are present, the runtime increments `tool_rounds` unless the call was seeded before generation. The round limit is `MAX_TOOL_ROUNDS = 10`; hitting it emits `AnswerSource::ToolLimitReached`. Code: `src/runtime/orchestration/engine.rs`. +- Tool execution is delegated to `run_tool_round()`, which returns one of four outcomes. `Completed` means all calls finished immediately. `ApprovalRequired` means the turn pauses with a `PendingAction`. `RuntimeDispatch` means the runtime selected the next tool call itself. `TerminalAnswer` means the runtime has enough information to end the turn without another backend round. Code: `src/runtime/orchestration/tool_round.rs`. +- Search to read transition can happen in three ways: the backend emits `[read_file: ...]` after a search result, `run_tool_round()` returns `RuntimeDispatch` to the preferred candidate after search, or a direct-read request is seeded before any generation. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/orchestration/engine.rs`. +- Read to answer transition is runtime-owned. After a completed tool round, the runtime sets `answer_phase = InvestigationEvidenceReady` when `investigation.evidence_ready()` becomes true, or `answer_phase = PostRead` for non-investigation read flows. The next generation then runs under `AnswerOnly`. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/investigation/investigation.rs`. +- Raw direct reads are a separate terminal path. If a seeded direct read completes in `DirectReadMode::Raw`, the runtime strips the tool-result wrapper with `direct_read_fallback_answer()` and finishes immediately. No synthesis generation is performed. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/protocol/response_text.rs`, `src/runtime/tests/finalization.rs`. +- Approved mutation success does not re-enter the backend. `handle_approve()` executes the approved tool, commits the tool result, invalidates the project snapshot cache, trims context, and finishes with `mutation_complete_final_answer()`. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/protocol/response_text.rs`. +- Provider switching is session-only. `ProvidersList` and `ProvidersUse` requests list or swap the active `ModelBackend` without persisting the change.

The function triggers on identifier-like tokens, explicit code-file tokens, or narrow lookup phrasing. Code: `src/runtime/investigation/prompt_analysis.rs`, `src/runtime/orchestration/engine.rs`. +- `detect_investigation_mode()` chooses one structural mode per turn. Priority order: `CallSiteLookup`, `UsageLookup`, `ConfigLookup`, `InitializationLookup`, `CreateLookup`, `RegisterLookup`, `LoadLookup`, `SaveLookup`, `DefinitionLookup`, `General`. Code: `src/runtime/investigation/investigation.rs`. +- Search queries are simplified before dispatch. `simplify_search_input()` reduces the query to a narrower literal token, and `weak_search_query_reason()` rejects empty, too-short, and exact `git` queries on investigation turns. Code: `src/runtime/investigation/search_query.rs`, `src/runtime/orchestration/tool_round.rs`. +- Prompt-derived search scope is an upper bound, not a hint. `run_tool_round()` injects the scope when the backend omits a search path, and clamps the path back to the prompt scope when the backend requests a broader or unrelated path. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/investigation/prompt_analysis.rs`. +- Search budget is per turn. `SearchBudget` allows one search unconditionally, a second search only if the first returned zero matches, and closes after that. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/orchestration/engine.rs`. +- Search results are classified immediately after dispatch. `InvestigationState::record_search_results()` rebuilds the current candidate sets, including source candidates, definition-only candidates, exact definition-site candidates, import-only candidates, config candidates, initialization/create/register/load/save/call-site candidates, and lockfile candidates. Code: `src/runtime/investigation/investigation.rs`. +- Candidate selection is mode-specific. `best_candidate_for_mode()` picks the first mode-specific candidate for config/initialization/create/register/load/save/definition/call-site lookups; the ranked `preferred_usage_candidate()` for usage lookups; the first source candidate for `General`; otherwise falls back to graph-promoted candidates from `InvestigationGraph.promoted_candidates()`, then the first search result. Code: `src/runtime/investigation/investigation.rs`. +- `InvestigationGraph` (petgraph, owned by `InvestigationState.graph`) records import edges when a file is read and definition edges when `lsp_definition` returns a target. `promoted_candidates()` returns unread nodes connected to any read node. This is advisory — graph candidates are consulted as fallbacks, not primary candidates. Code: `src/runtime/investigation/graph.rs`. +- Usage lookup has an additional ranking path. `preferred_usage_candidate()` prefers non-definition, non-import, normal source candidates with more non-definition matches. Code: `src/runtime/investigation/investigation.rs`. +- Broad usage lookup can require two useful reads instead of one. `usage_lookup_is_broad()` enables that policy for `UsageLookup` turns that are unscoped or scoped to something that does not look like a specific file. `record_search_results()` raises `useful_candidate_reads_target` to `2` when at least two substantive usage candidates exist. Code: `src/runtime/orchestration/engine_guards.rs`, `src/runtime/investigation/investigation.rs`. +- `record_read_result()` is the evidence gate. It increments `files_read_count`, tracks candidate reads, and either accepts the read as useful evidence or returns a `RecoveryKind` that forces recovery behavior for definition-only, import-only, non-config, non-initialization, non-create, non-register, non-load, non-save, non-call-site, or lockfile reads. Code: `src/runtime/investigation/investigation.rs`. +- Evidence readiness is strict. `InvestigationState::evidence_ready()` becomes true only when the turn has a non-empty search result and `useful_accepted_candidate_reads >= useful_candidate_reads_target`. Search text alone never satisfies this condition. Code: `src/runtime/investigation/investigation.rs`. +- The runtime can choose the next read itself. After a search, `run_tool_round()` may return `RuntimeDispatch` to the preferred usage candidate, a definition-site recovery candidate, a mode-selected candidate after a non-candidate read, or a graph-promoted candidate. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/investigation/investigation.rs`. + +## Enforcement and Guards + +- **Non-candidate read rejection**: after `search_produced_results()` is true on an investigation turn and there is no direct-read request, every `read_file` call is checked against the current candidate set. If outside the set, `run_tool_round()` increments `non_candidate_read_attempts` and either redirects, injects a correction, or terminates. Code: `src/runtime/orchestration/tool_round.rs`. +- **Redirection (Phase 18.1)**: implemented as runtime dispatch, not a phase switch. In `General` mode, if the backend reads a doc-like candidate (`README`, `docs/...`, `benchmarks/...`) before any candidate read and a better source candidate exists, `run_tool_round()` returns `RuntimeDispatch` to that source candidate. On the first non-candidate read attempt, if a preferred candidate exists and has not already been read, `run_tool_round()` returns `RuntimeDispatch` to it. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/tests/investigation.rs`. +- **Non-candidate read correction**: if dispatch is not possible on the first non-candidate read attempt, `run_tool_round()` injects `non_candidate_read_correction(...)`. The second non-candidate read attempt returns `TerminalAnswer` with `RuntimeTerminalReason::ReadFileFailed`. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/protocol/response_text.rs`. +- **Answer guard**: on investigation turns after search results exist, the runtime extracts project-looking paths from the assistant response. If the turn has a prompt-derived scope and the answer cites any path outside that scope, the runtime emits `InsufficientEvidence`. If the answer cites any path not in `reads_this_turn`, the runtime also emits `InsufficientEvidence`. No correction round is issued for answer-guard failures. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/orchestration/engine_guards.rs`. +- **Post-evidence restrictions**: once `answer_phase` is active, generation runs under `ToolSurface::AnswerOnly`. If the backend still emits tools, the runtime discards the reply, injects `TURN_COMPLETE_ANSWER_ONLY` or `EVIDENCE_READY_ANSWER_ONLY`, and retries once. The next violation terminates with `RepeatedToolAfterAnswerPhase` or `RepeatedToolAfterEvidenceReady`. Code: `src/runtime/orchestration/engine.rs`, `src/runtime/protocol/response_text.rs`. +- **Search budget closure**: if the backend searches after the budget is closed, `run_tool_round()` injects `SEARCH_BUDGET_EXCEEDED` on the first violation. Continued searching terminates with `RepeatedSearchBudgetViolation`. If both allowed searches were empty and no file was read, the runtime terminates as `InsufficientEvidence`. Code: `src/runtime/orchestration/tool_round.rs`, `src/runtime/orchestration/engine.rs`. +- **Other turn-local guards**: `list_dir` is rejected before any search on investigation turns, repeated reads of the same file are rejected, candidate reads are capped at `MAX_CANDIDATE_READS_PER_INVESTIGATION = 2` per investigation turn, and total successful reads are capped at `MAX_READS_PER_TURN = 3` per turn. Code: `src/runtime/orchestration/tool_round.rs`. +- **Runtime terminal conditions**: the terminal reasons are the `RuntimeTerminalReason` variants in `src/runtime/types.rs`. Emission sites are split between `run_tool_round()` for dispatch-time terminals and `run_turns_with_initial_reads()` / `handle_reject()` for answer-admission and approval terminals. Code: `src/runtime/types.rs`, `src/runtime/orchestration/tool_round.rs`, `src/runtime/orchestration/engine.rs`. + +## Failure Modes (Grounded in Tests) + +- **Non-candidate read can still end as grounded success**: `non_candidate_read_after_search_dispatches_preferred_candidate()` shows the first bad read replaced by a runtime-selected read, after which the answer is admitted as `ToolAssisted`. Code: `src/runtime/tests/investigation.rs`. +- **Non-candidate read can still end as terminal failure**: `read_must_come_from_current_search_results()` shows the redirect path, but the later answer cites a path that was never read. The answer guard discards that answer and terminates with `InsufficientEvidence`. Code: `src/runtime/tests/investigation.rs`. +- **General-mode non-candidate correction names a concrete replacement**: `general_mode_non_candidate_correction_names_first_search_candidate()` shows the runtime injecting a `read_file` correction naming a specific file from search results. Code: `src/runtime/tests/investigation.rs`. +- **Usage vs definition confusion is treated as insufficient evidence**: `usage_lookup_definition_only_reads_produce_insufficient_evidence()` shows a usage question answered from a definition-only read being rejected. Code: `src/runtime/tests/finalization.rs`. +- **Answer guard rejection suppresses the bad answer**: `answer_citing_unread_path_triggers_insufficient_evidence()` shows a final answer citing an unread file not being surfaced. Code: `src/runtime/tests/finalization.rs`. +- **Malformed tool syntax is corrected once, then bounded**: `malformed_block_triggers_correction_and_retries()` shows one malformed block corrected; `repeated_malformed_write_syntax_terminals_deterministically()` shows the second violation terminating with `RepeatedMalformedToolSyntax`. Code: `src/runtime/tests/tool_round.rs`, `src/runtime/tests/finalization.rs`. +- **Garbled edit repair is handled separately**: `edit_repair_correction_injected_on_garbled_repair_after_failure()` and `repeated_garbled_edit_repair_terminals_without_surfacing_malformed_block()` show the `EDIT_REPAIR_CORRECTION` path and the `RepeatedGarbledEditRepair` terminal. Code: `src/runtime/tests/approval.rs`. +- **Mutation resolver failure is terminal**: `mutation_resolver_failure_terminates_immediately()` shows a write outside the project root ending as `MutationFailed` without executing later search steps.

If the tool requires `&mut` state not available in `ToolRegistry::dispatch()` (e.g., `LspManager`), add an intercept in `run_tool_round()` in `src/runtime/orchestration/tool_round.rs` before the `registry.dispatch()` call. +11. Add a unit test in the new tool file and an integration test in `src/runtime/tests/`. + +## Changing Retrieval Behavior + +1. Identify which of the three layers needs to change: + - **Candidate classification**: `InvestigationState::record_search_results()` in `src/runtime/investigation/investigation.rs`. + - **Read acceptance**: `InvestigationState::record_read_result()` in the same file. + - **Answer admission**: the answer-guard branches in `run_turns_with_initial_reads()` in `src/runtime/orchestration/engine.rs`. +2. If adding a new gate in `record_read_result()`, follow the `_correction_issued` bool pattern — fire each correction exactly once per turn. +3. If changing `evidence_ready()`, ensure it remains the single source of truth for evidence state; search text alone must never satisfy it. +4. If adding a new `InvestigationMode`, add it to `detect_investigation_mode()` in priority order, add a case in `best_candidate_for_mode()`, and add a corresponding gate in `record_read_result()`. +5. Update both candidate classification and answer admission together. Changing only one layer creates false terminals or false admissions. +6. New `InvestigationState` fields must reset in `new()` (the large initializer). +7. Add an integration test in `src/runtime/tests/` that would have caught the regression. + +## Changing Mutation Behavior + +1. Do not make a mutating tool `Immediate`. Mutations are designed around `PendingAction` + `execute_approved()`. +2. Keep `spec().execution_kind` aligned with the actual `ToolRunResult` returned by `run()`. The `debug_assert!` in `tool_round.rs` checks this at test time. +3. Approval-time revalidation is required in `execute_approved()`: + - `EditFileTool`: recheck that the search text still exists in the current file contents. + - `WriteFileTool`: recheck path validity and parent existence. +4. After a successful mutation, `handle_approve()` must commit the tool result, invalidate the project snapshot cache, and end with `mutation_complete_final_answer()`. Do not re-enter the backend. +5. After a rejected mutation, `handle_reject()` must inject a tool error and end with `rejection_final_answer()`. Do not re-enter the backend. +6. If a new tool can affect project structure, add snapshot cache invalidation in the approval success branch of `engine.rs`. +7. Shell commands are gated by `is_permitted_shell_command()` — only `cargo` is permitted. Do not weaken this allowlist without updating the invariant documentation. diff --git a/.claude/rules/slice-discipline.md b/.claude/rules/slice-discipline.md new file mode 100644 index 0000000..60193c9 --- /dev/null +++ b/.claude/rules/slice-discipline.md @@ -0,0 +1,32 @@ +# Slice Implementation Discipline + +## The Pattern (follow exactly) +1.

Tests 1, 2, 8, and 12 all affected. Only explicit direct reads (Test 9) behave as intended. Fix required in Phase 28. +- 27.4 secondary issue: when multiple file reads occur in a session, only the most recent has the Ctrl+O toggle — previous reads display full content inline (Test 12).

Backslash path separator issue in search_code results on Windows identified as remaining open item. +- Test 18 (test validation loop) not run this session — deferred. +- Test 25 (compound investigation+mutation) not run this session — known small model limitation, works with OpenAI per Phase 25 notes. + +--- + +## Remaining failure modes + +- **27.4 Ctrl+O regression**: toggle hides investigation model answers, not just file content. Only direct reads behave correctly. High priority Phase 28 fix. +- **27.4 multi-read toggle**: only most recent file read in session has Ctrl+O toggle. Previous reads show full content. Phase 28 fix. +- **Windows backslash paths**: search_code returns Windows-style backslash paths in match output on Windows. Path normalization in result parsing needs fix. Phase 28. +- **Answer guard retry on verbose models**: gpt-4o-mini still occasionally cites related unread files (Tests 3, 6). Guard fires and recovers correctly but adds a round. Model behavior, not a runtime bug. + +--- + +## Conclusion + +Phase 27 baseline established. Investigation correctness significantly improved — Tests 3 and 6 which were FAILs in Phase 25 now PASS with definition candidate dispatch working end-to-end. No regressions on existing passing tests. One new regression introduced by 27.4 (Ctrl+O toggle hiding investigation answers) requires a targeted fix in Phase 28. 802 tests passing.

Phase 27 and 28 baselines had these as PASS or PARTIAL — these are now FAIL. Root cause: `compute_read_target()` signals not triggering target raise. Needs investigation as Phase 29.14. +- **Test 2 — LSP seeding on Python files causes model loop:** `lsp_definition_seeded` fires on Python `.py` files despite rust-analyzer not supporting them. LSP returns empty, but the model enters a recovery loop re-reading the same file repeatedly instead of falling through cleanly. The `.rs` extension guard in the seeding block is not preventing dispatch for Python files. Needs fix as Phase 29.14. +- **Test 22 — LSP seeding not firing when declaration line truncated:** `search_code` shows 15 of 17 matches. The declaration line for `run_tool_round` is not in the shown results, so `is_declaration_line()` finds no match and seeding falls back to the first match (a call site), which returns no definition. Known limitation of search truncation at 15 results. Lower priority — not a regression. +- **LSP cold start latency:** First rust-analyzer query per session takes 20–25 seconds while the server indexes the project. Subsequent queries in the same session respond in 3–5 seconds. Expected behavior — documented for user awareness. +- **Python LSP not supported:** All LSP calls on `.py` files return empty (expected — rust-analyzer handles Rust only). Graceful fallback to `read_file` works correctly in Tests 14, 16, 21. The seeding guard needs to check file extension before dispatching (Test 2 regression). \ No newline at end of file diff --git a/docs/benchmarks/runs/2026-05-28-phase29-regression.md b/docs/benchmarks/runs/2026-05-28-phase29-regression.md new file mode 100644 index 0000000..2a2523c --- /dev/null +++ b/docs/benchmarks/runs/2026-05-28-phase29-regression.md @@ -0,0 +1,53 @@ +# Benchmark Run — 2026-05-28 — Phase 29 Regression + +Date: 2026-05-28 +Version: 0.14.54 +Backend: openai +Model: gpt-4o-mini +Machine: MacBook Air M2, 8GB RAM + +--- + +## Context + +Post-29.14 regression run.
