## [0.23.0] - 2026-02-23

### Added

- `default-test-first-mini` builtin piece for test-first development workflow
- `auto_fetch` global config: opt-in remote fetch before cloning to keep clones up-to-date (`default: false`)
- `base_branch` config (global/project): specify the base branch for clone creation (defaults to remote default branch)
- `model` project config: override model at the project level (`.takt/config.yaml`)
- `concurrency` project config: set parallel task count per project for `takt run`
- `--create-worktree` support in pipeline mode for worktree-based execution
- `skipTaskList` option: interactive "Execute" action skips adding to `tasks.yaml`
- `takt list` now displays GitHub Issue numbers alongside task names

- `auto-tag.yml` tags PR head SHA instead of merge commit for correct hotfix code publishing
- Session reader falls back to JSONL file scanning when `sessions-index.json` is missing or invalid
- `ProjectLocalConfig` type normalized to camelCase (`auto_pr`→`autoPr`, `draft_pr`→`draftPr`) — YAML snake_case preserved
- `getLocalLayerValue` simplified from switch-case to dynamic property lookup

### Fixed

- `repertoire add` pipe stdin: multiple `confirm()` calls failed when reading from piped stdin due to readline destroying buffered lines (#334)
- Movement provider override precedence in `AgentRunner`: step provider was incorrectly overridden by global config
- Project-level `model` config was silently ignored — `getLocalLayerValue` was missing the `model` case
- PR creation failure now properly propagated as task failure with error message (#345)
- Claude session resume candidates now fall back to JSONL file scanning when `sessions-index.json` is unavailable

### Internal

- CI: PR checks for lint, test, e2e:mock (`ci.yml`)
- Expanded e2e test coverage for repertoire (#364)
- New test suites: clone, config, postExecution, session-reader, selectAndExecute-skipTaskList, taskStatusLabel, pipelineExecution
- Refactored: project config case normalization (#358), clone manager (#359), pipeline steps extraction, confirm pipe reader singleton, provider resolution (#362)

## [0.22.0] - 2026-02-22

### Added

- **Repertoire package system** (`takt repertoire add/remove/list`): Import and manage external TAKT packages from GitHub — `takt repertoire add github:{owner}/{repo}@{ref}` downloads packages to `~/.takt/repertoire/` with atomic installation, version compatibility checks, lock files, and package content summary before confirmation
- **@scope references in piece YAML**: Facet references now support `@{owner}/{repo}/{facet-name}` syntax to reference facets from installed repertoire packages (e.g., `persona: @nrslib/takt-fullstack/expert-coder`)
- **4-layer facet resolution**: Upgraded from 3-layer (project → user → builtin) to 4-layer (package-local → project → user → builtin) — repertoire package pieces automatically resolve their own facets first
- **Repertoire category in piece selection**: Installed repertoire packages automatically appear as subcategories under a "repertoire" category in the piece selection UI
- **Build gate in implement/fix instructions**: `implement` and `fix` builtin instructions now require build (type check) verification before test execution
- **Repertoire package documentation**: Added comprehensive docs for the repertoire package system ([en](./docs/repertoire.md), [ja](./docs/repertoire.ja.md))

### Changed

- **BREAKING: Facets directory restructured**: Facet directories moved under a `facets/` subdirectory at all levels — `builtins/{lang}/{facetType}/` → `builtins/{lang}/facets/{facetType}/`, `~/.takt/{facetType}/` → `~/.takt/facets/{facetType}/`, `.takt/{facetType}/` → `.takt/facets/{facetType}/`. Migration: move your custom facet files into the new `facets/` subdirectory
- Contract string hardcoding prevention rule added to coding policy and architecture review instruction

### Fixed

- Override piece validation now includes repertoire scope via the resolver
- `takt export-cc` now reads facets from the new `builtins/{lang}/facets/` directory structure
- `confirm()` prompt now supports piped stdin (e.g., `echo "y" | takt repertoire add ...`)
- Suppressed `poll_tick` debug log flooding during iteration input wait
- Piece resolver `stat()` calls now catch errors gracefully instead of crashing on inaccessible entries

### Internal

- Comprehensive repertoire test suite: atomic-update, repertoire-paths, file-filter, github-ref-resolver, github-spec, list, lock-file, pack-summary, package-facet-resolution, remove-reference-check, remove, takt-repertoire-config, tar-parser, takt-repertoire-schema
- Added `src/faceted-prompting/scope.ts` for @scope reference parsing, validation, and resolution
- Added scope-ref tests for the faceted-prompting module
- Added `inputWait.ts` for shared input-wait state to suppress worker pool log noise
- Added piece-selection-branches and repertoire e2e tests

### Changed

- **Config system overhaul**: Replaced `loadConfig()` bulk merge with per-key `resolveConfigValue()` resolution — global < piece < project < env priority with source tracking and `OptionsBuilder` merge direction control (#324)

### Fixed

- **Retry command scope and messaging**: Fixed retry command to show correct available range and guidance text
- **Retry task `completed_at` leak**: Clear `completed_at` when moving a failed task back to running via `startReExecution`, preventing Zod validation errors
- **OpenCode multi-turn hang**: Removed `streamAbortController.signal` from OpenCode server startup so subsequent turns no longer hang; restored `sessionId` carry-over for multi-turn conversations
- **Romaji conversion stack overflow**: Prevented stack overflow on long task names during romaji conversion

## [0.20.1] - 2026-02-20

### Fixed

- Pin `@opencode-ai/sdk` to `<1.2.7` to fix broken v2 exports that caused `Cannot find module` errors on `npm install -g takt` (#329)

## [0.20.0] - 2026-02-19

### Added

- **Faceted Prompting module** (`src/faceted-prompting/`): Standalone library for facet composition, resolution, template rendering, and truncation — zero dependencies on TAKT internals. Includes `DataEngine` interface with `FileDataEngine` and `CompositeDataEngine` implementations for pluggable facet storage
- **Analytics module** (`src/features/analytics/`): Local-only review quality metrics collection — event types (review findings, fix actions, movement results), JSONL writer with date-based rotation, report parser, and metrics computation
- **`takt metrics review` command**: Display review quality metrics (re-report counts, round-trip ratio, resolution iterations, REJECT counts by rule, rebuttal resolution ratio) with configurable time window (`--since`)
- **`takt purge` command**: Purge old analytics event files with configurable retention period (`--retention-days`)
- **`takt reset config` command**: Reset global config to builtin template with automatic backup of the existing config
- **PR duplicate prevention**: When a PR already exists for the current branch, push and comment on the existing PR instead of creating a duplicate (#304)
- Retry mode now positions the cursor on the failed movement when selecting which movement to retry
- E2E tests for run-recovery and config-priority scenarios

### Changed

- **README overhaul**: Compressed from ~950 lines to ~270 lines — details split into dedicated docs (`docs/configuration.md`, `docs/cli-reference.md`, `docs/task-management.md`, `docs/ci-cd.md`, `docs/builtin-catalog.md`) with Japanese equivalents. Redefined product concept around 4 value axes: batteries included, practical, reproducible, multi-agent
- **Config system refactored**: Unified configuration resolution to `resolveConfigValue()` and `loadConfig()`, eliminating scattered config access patterns across the codebase
- **`takt config` command removed**: Replaced by `takt reset config` for resetting to defaults
- Builtin config templates refreshed with updated comments and structure
- `@anthropic-ai/claude-agent-sdk` updated to v0.2.47
- Instruct mode prompt improvements for task re-instruction

### Fixed

- Fixed issue where builtin piece file references used absolute path instead of relative (#304)
- Removed unused imports and variables across multiple files

- Added E2E tests for config priority and run recovery scenarios
- Added `postExecution.test.ts` for PR creation flow testing
- Cleaned up unused imports and variables

## [0.19.0] - 2026-02-18

### Added

- Dedicated retry mode for failed tasks — conversation loop with failure context (error details, failed movement, last message), run session data, and piece structure injected into the system prompt
- Dedicated instruct system prompt for completed/failed task re-instruction — injects task name, content, branch changes, and retry notes directly into the prompt instead of using the generic interactive prompt
- Direct re-execution from `takt list` — "execute" action now runs the task immediately in the existing worktree instead of only requeuing to pending
- `startReExecution` atomic task transition — moves a completed/failed task directly to running status, avoiding the requeue → claim race condition
- Worktree reuse in task execution — reuses existing clone directory when it's still on disk, skipping branch name generation and clone creation
- Task history injection into interactive and summary system prompts — completed/failed/interrupted task summaries are included for context
- Previous run reference support in interactive and instruct system prompts — users can reference logs and reports from prior runs
- `findRunForTask` and `getRunPaths` helpers for automatic run session lookup by task content
- `isStaleRunningTask` process helper extracted from TaskLifecycleService for reuse

### Changed

- Interactive module split: `interactive.ts` refactored into `interactive-summary.ts`, `runSelector.ts`, `runSessionReader.ts`, and `selectorUtils.ts` for better cohesion
- `requeueTask` now accepts generic `allowedStatuses` parameter instead of only accepting `failed` tasks
- Instruct/retry actions in `takt list` use the worktree path for conversation and run data lookup instead of the project root
- `save_task` action now requeues the task (saves for later execution), while `execute` action runs immediately

### Internal

- Removed `DebugConfig` from models, schemas, and global config — simplified to verbose mode only
- Added stdin simulation test helpers (`stdinSimulator.ts`) for E2E conversation loop testing
- Added comprehensive E2E tests for retry mode, interactive routes, and run session injection
- Added `check:release` npm script for pre-release validation

## [0.18.2] - 2026-02-18

### Added

- Added `codex_cli_path` global config option and `TAKT_CODEX_CLI_PATH` environment variable to override the Codex CLI binary path used by the Codex SDK (#292)
  - Supports strict validation: absolute path, file existence, executable permission, no control characters
  - Priority: `TAKT_CODEX_CLI_PATH` env var > `codex_cli_path` in config.yaml > SDK vendored binary

## [0.18.1] - 2026-02-18

### Added

- Added multi-tenant data isolation section and authorization-resolver consistency code examples to security knowledge
- Added "prefer project scripts" rule to coding policy — detects direct tool invocation (e.g., `npx vitest`) when equivalent npm scripts exist

## [0.18.0] - 2026-02-17

### Added

- **`deep-research` builtin piece**: Multi-angle research workflow with four steps — plan, deep-dive, analyze, and synthesize
- Project-level `.takt/` facets (pieces, personas, policies, knowledge, instructions, output-contracts) are now version-controllable (#286)
- New research facets added: research policy, knowledge, comparative-analysis knowledge, dedicated persona, and instructions

### Changed

- Refactored the `research` piece — separated rules and knowledge embedded in the persona into policy, knowledge, and instruction files, conforming to the faceted design
- Added knowledge/policy references to existing pieces (expert, expert-cqrs, backend, backend-cqrs, frontend)

### Fixed

- Fixed a bug where facet directories were not tracked because `.takt/` path prefix was written with `.takt/` prefix in the `.takt/.gitignore` template (dotgitignore)

### Internal

- Created knowledge facet style guide (`KNOWLEDGE_STYLE_GUIDE.md`)
- Added regression tests for dotgitignore patterns

## [0.17.3] - 2026-02-16

### Added

- Added API client generation consistency rules to builtin AI anti-pattern policy and frontend knowledge — detects handwritten clients mixed into projects where generation tools (e.g., Orval) exist

### Fixed

- Fixed EPERM crash when releasing task store locks — replaced file-based locking with in-memory guard

### Internal

- Unified vitest configuration for e2e tests and added `forceExit` option to prevent zombie workers

## [0.17.2] - 2026-02-15

### Added

- **`expert-mini` and `expert-cqrs-mini` pieces**: Lightweight variants of Expert pieces — plan → implement → parallel review (AI anti-pattern + supervisor) → fix workflow
- Added new pieces to "Mini" and "Expert" piece categories

### Fixed

- Fixed an error being thrown when permission mode could not be resolved — now falls back to `readonly`

## [0.17.1] - 2026-02-15

### Changed

- Changed `.takt/.gitignore` template to allowlist approach — ignores all files by default and tracks only `config.yaml`. Prevents ignore gaps when new files are added

## [0.17.0] - 2026-02-15

### Added

- **Mini piece series**: Added `default-mini`, `frontend-mini`, `backend-mini`, `backend-cqrs-mini` — lightweight development pieces with parallel review (AI anti-pattern + supervisor) as successors to `coding`/`minimal`
- Added "Mini" category to piece categories
- **`supervisor-validation` output contract**: Requirements Fulfillment Check table format that presents code evidence per requirement
- **`getJudgmentReportFiles()`**: Phase 3 status judgment target reports can now be filtered via `use_judge` flag
- Added `finding_id` tracking to output contracts (new/persists/resolved sections for tracking findings across iterations)

### Changed

- **BREAKING: Removed `coding` and `minimal` pieces** — replaced by the mini piece series. Migration: `coding` → `default-mini`, `minimal` → `default-mini`
- **BREAKING: Unified output contract to item format** — `use_judge` (boolean) and `format` (string) fields are now required; `OutputContractLabelPath` (label:path format) is removed
- Moved runtime environment directory from `.runtime` to `.takt/.runtime`
- Enhanced supervisor requirements verification: extracts requirements individually and verifies one-by-one against code (file:line) — "roughly complete" is no longer valid grounds for APPROVE

### Fixed

- Added retry mechanism for deleting clone/worktree directories (`maxRetries: 3`, `retryDelay: 200`) — reduces transient deletion failures caused by file locks

### Internal

- Removed `review-summary` output contract (consolidated into `supervisor-validation`)
- Updated all builtin pieces, e2e fixtures, and tests to the new output contract format

## [0.16.0] - 2026-02-15

### Added

- **Provider-specific permission profiles (`provider_profiles`)**: Define default permission modes per provider and per-movement overrides in global (`~/.takt/config.yaml`) and project (`.takt/config.yaml`) config — 5-level priority resolution (project override → global override → project default → global default → `required_permission_mode` floor)

### Changed

- **BREAKING: `permission_mode` → `required_permission_mode`**: Renamed movement's `permission_mode` field to `required_permission_mode` — acts as a floor value; the actual permission mode is resolved via `provider_profiles`. Old `permission_mode` is rejected by `z.never()`, no backward compatibility
- Rewrote builtin `config.yaml` template: reorganized comments, added `provider_profiles` description and examples, added OpenCode-related settings

### Internal

- Added tests for provider profile resolution (global-provider-profiles, project-provider-profiles, permission-profile-resolution, options-builder)
- Added missing `loadProjectConfig` mock to parallel execution tests

## [0.15.0] - 2026-02-15

### Added

- **Runtime environment presets**: `piece_config.runtime.prepare` and global config `runtime.prepare` allow environment preparation scripts to run automatically before piece execution — builtin presets (`gradle`, `node`) isolate dependency resolution and cache setup to the `.runtime/` directory
- **Loop monitor judge instruction**: `loop_monitors` judge config now supports `instruction_template` field — externalizes loop judgment instructions as an instruction facet, applied to builtin pieces (expert, expert-cqrs)

### Internal

- Added runtime environment tests (runtime-environment, globalConfig-defaults, models, provider-options-piece-parser)
- Added provider e2e test (runtime-config-provider)

## [0.14.0] - 2026-02-14

### Added

- **`takt list` instruct mode (#267)**: Added instruct mode for issuing additional instructions to existing branches — refine requirements through a conversation loop before piece execution
- **`takt list` completed task actions (#271)**: Added diff view and branch operations (merge, delete) for completed tasks
- **Claude sandbox configuration**: `provider_options.claude.sandbox` supports `excluded_commands` and `allow_unsandboxed_commands`
- **`provider_options` global/project config**: `provider_options` can now be set in `~/.takt/config.yaml` (global) and `.takt/config.yaml` (project) — acts as lowest-priority fallback for piece-level settings

### Changed

- **Consolidated provider/model resolution into AgentRunner**: Fixed provider resolution to prioritize project config over custom agent config. Added step-level `stepModel`/`stepProvider` overrides
- **Unified post-execution flow**: Shared `postExecution.ts` for interactive mode and instruct mode (auto-commit, push, PR creation)
- **Added scope-narrowing prevention to instructions**: plan, ai-review, and supervise instructions now require detecting missed requirements — plan mandates per-requirement "change needed/not needed" judgments with rationale, supervise prohibits blindly trusting plan reports

### Fixed

- Fixed a bug where interactive mode options were displayed during async execution (#266)
- Fixed OpenCode session ID not being carried over during parallel execution — server singleton prevents race conditions in parallel runs
- Extended OpenCode SDK server startup timeout from 30 seconds to 60 seconds

### Internal

- Large-scale task management refactor: split `TaskRunner` responsibilities into `TaskLifecycleService`, `TaskDeletionService`, and `TaskQueryService`
- Split `taskActions.ts` by feature: `taskBranchLifecycleActions.ts`, `taskDiffActions.ts`, `taskInstructionActions.ts`, `taskDeleteActions.ts`
- Added `postExecution.ts`, `taskResultHandler.ts`, `instructMode.ts`, `taskActionTarget.ts`
- Consolidated piece selection logic into `pieceSelection/index.ts` (extracted from `selectAndExecute.ts`)
- Added/expanded tests: instructMode, listNonInteractive-completedActions, listTasksInteractiveStatusActions, option-resolution-order, taskInstructionActions, selectAndExecute-autoPr, etc.
- Added Claude Code sandbox option (`dangerouslyDisableSandbox`) to E2E tests
- Added `OPENCODE_CONFIG_CONTENT` to `.gitignore`

## [0.13.0] - 2026-02-13

### Added

- **Team Leader movement**: New movement type where a team leader agent dynamically decomposes a task into sub-tasks (Parts) and executes multiple part agents in parallel — supports `team_leader` config (persona, maxParts, timeoutMs, partPersona, partEdit, partPermissionMode) (#244)
- **Structured Output**: Introduced JSON Schema-based structured output for agent calls — three schemas for task decomposition, rule evaluation, and status judgment added to `builtins/schemas/`. Supported by both Claude and Codex providers (#257)
- **`provider_options` piece-level config**: Provider-specific options (`codex.network_access`, `opencode.network_access`) can now be set at piece level (`piece_config.provider_options`) and individual movements — Codex/OpenCode network access enabled in all builtin pieces
- **`backend` builtin piece**: New backend development piece — parallel specialist review by backend, security, and QA reviewers
- **`backend-cqrs` builtin piece**: New CQRS+ES backend development piece — parallel specialist review by CQRS+ES, security, and QA reviewers
- **AbortSignal for part timeouts**: Added timeout control and parent signal propagation via AbortSignal for Team Leader part execution
- **Agent usecase layer**: `agent-usecases.ts` consolidates agent call usecases (`decomposeTask`, `executeAgent`, `evaluateRules`) and centralizes structured output injection

### Changed

- **BREAKING: Public API cleanup**: Significantly narrowed the public API in `src/index.ts` — internal implementation details (session management, Claude/Codex client internals, utility functions, etc.) are no longer exported, reducing the API surface to a stable minimum (#257)
- **Revamped Phase 3 judgment logic**: Removed `JudgmentDetector`/`FallbackStrategy` and consolidated into `status-judgment-phase.ts` with structured output-based judgment. Improves stability and maintainability (#257)
- **Report phase retry improvement**: Report Phase (Phase 2) now automatically retries with a new session when it fails (#245)
- **Unified Ctrl+C shutdown**: Removed `sigintHandler.ts` and consolidated into `ShutdownManager` — graceful shutdown → timeout → force-kill in three stages, unified across all providers (#237)
- **Scope-deletion guardrails**: Added rules to coder persona prohibiting deletions and structural changes outside the task instruction scope. Added scope discipline and reference material priority rules to planner persona
- Added design token and theme scope guidance to frontend knowledge
- Improved architecture knowledge (both en/ja)

### Fixed

- Fixed checkout failure for existing branches during clone — now passes `--branch` to `git clone --shared` then removes the remote
- Removed `#` from issue-referenced branch names (`takt/#N/slug` → `takt/N/slug`)
- Resolved deprecated tool dependency in OpenCode report phase; migrated to permission-based control (#246)
- Removed unnecessary exports to ensure public API consistency

### Internal

- Added Team Leader tests (engine-team-leader, team-leader-schema-loader, task-decomposer)

- Refactored E2E test helpers (extracted shared setup functions)
- Removed `judgment/` directory (JudgmentDetector, FallbackStrategy)
- Added `ruleIndex.ts` utility (1-based → 0-based index conversion)

## [0.12.1] - 2026-02-11

### Fixed

- Fixed silent fallthrough to a new session when the session was not found — now shows an info message when no session is detected

### Internal

- Set OpenCode provider report phase to deny (prevents unnecessary writes in Phase 2)
- Skip copying `tasks/` directory during project initialization (TASK-FORMAT is no longer needed)
- Added stream diagnostics utility (`streamDiagnostics.ts`)

## [0.12.0] - 2026-02-11

### Added

- **OpenCode provider**: Native support for OpenCode as a third provider — SDK integration via `@opencode-ai/sdk/v2`, permission mapping (readonly/edit/full → reject/once/always), SSE stream handling, retry mechanism (up to 3 times), and hang detection with 10-minute timeout (#236, #238)
- **Arpeggio movement**: New movement type for data-driven batch processing — CSV data source with batch splitting, template expansion (`{line:N}`, `{col:N:name}`, `{batch_index}`), concurrent LLM calls (Semaphore-controlled), and concat/custom merge strategies (#200)
- **`frontend` builtin piece**: Frontend development piece — React/Next.js knowledge injection, coding/testing policy, parallel architecture review

- **Improved review output**: Updated review output format; moved past reports to history log (#209)
- **Simplified builtin pieces**: Further streamlined top-level declarations across all builtin pieces

### Fixed

## [0.11.1] - 2026-02-10

### Fixed

- Fixed AI Judge to route through provider system — changed `callAiJudge` from a Claude-only implementation to provider-based (`runAgent`), enabling correct AI judgment with the Codex provider
- Reduced instruction bloat — set `pass_previous_response: false` in implement/fix movements, prioritizing reports in the Report Directory as primary information source (en/ja)

- **Prompt log viewer**: `tools/prompt-log-viewer.html` for visualizing prompt-response pairs during debugging
- Auto-PR base branch now set to the current branch before branch creation

### Changed

## [0.6.0] - 2026-02-05

Formal release of RC1/RC2 content. No functional changes.

## [0.6.0-rc1] - 2026-02-05

### Fixed

- Fixed infinite loop between ai_review and ai_fix: resolved issue where ai_fix judging "no fix needed" caused a return to plan and restarted the full pipeline
  - Added `ai_no_fix` arbitration step (architecture-reviewer judges the ai_review vs ai_fix conflict)
  - Changed ai_fix "no fix needed" route from `plan` to `ai_no_fix`
  - Affected pieces: default, expert, expert-cqrs (en/ja)

### Changed

- Changed default piece parallel reviewer from security-review to qa-review (optimized for TAKT development)
- Moved qa-reviewer agent from `expert/` to `default/` and rewrote with focus on test coverage
- Added iteration awareness to ai_review instruction (first iteration: comprehensive review; subsequent: prioritize fix verification)

### Internal

- Restricted auto-tag workflow to merges from release/ branches only, unified publish job (resolves chained trigger failure due to GITHUB_TOKEN limitations)
- Removed postversion hook (conflicts with release branch flow)
- Updated tests: adapted to security-reviewer → qa-reviewer change

## [0.6.0-rc] - 2026-02-05

### Added

- **`coding` builtin piece**: Lightweight development piece — design → implement → parallel review → fix (fast feedback loop without plan/supervise steps)
- **`conductor` agent**: Dedicated agent for Phase 3 judgment. Reads reports and responses to output judgment tags
- **Phase 3 judgment fallback strategy**: 4-stage fallback (AutoSelect → ReportBased → ResponseBased → AgentConsult) to improve judgment accuracy (`src/core/piece/judgment/`)
- **Session state management**: Saves task execution results (success/error/interrupted) and displays previous result on next interactive mode startup (#89)
- TAKT meta information (piece structure, progress) injection mechanism for agents
- **`/play` command**: Immediately executes task in interactive mode
- E2E test infrastructure: mock/provider-compatible test infrastructure, 10 E2E test specs, test helpers (isolated-env, takt-runner, test-repo)
- Added detection rule for "logically unreachable defensive code" to review agents

### Changed

- Changed Phase 3 judgment logic from session-resume approach to conductor agent + fallback strategy (improved judgment stability)
- Refactored CLI routing as `executeDefaultAction()` function, reusable as fallback from slash commands (#32)
- Input starting with `/` or `#` is now accepted as task instruction when no command/issue is found (#32)
- Simplified `isDirectTask()`: only issue references execute directly, all others go to interactive mode
- Removed `pass_previous_response: true` from all builtin pieces (redundant as it is the default behavior)

### Internal

- Added E2E test config files (vitest.config.e2e.ts, vitest.config.e2e.mock.ts, vitest.config.e2e.provider.ts)
- Added `getReportFiles()`, `hasOnlyOneBranch()`, `getAutoSelectedTag()` to `rule-utils.ts`
- Added report content and response-based judgment instruction generation to `StatusJudgmentBuilder`
