discrepancy (T013)**: The code used `QuoteStyle::Necessary` but FR-054 and the plan's coding standards require `QuoteStyle::Always`. Fixed this, which required updating two existing test assertions (`index_is_used_for_sorted_output`, `process_accepts_named_index_variant`) that checked raw CSV output with `starts_with()`. ++ ++2. **Rustdoc link warnings**: Initial Rustdoc comments linked to private items (`run_operation`, `preprocess_cli_args`) and had a redundant explicit link. Fixed by using plain code formatting for private items and simplified link syntax. ++ ++3. **Boolean format coverage**: Existing tests only covered 2 of 6 boolean format pairs ("Yes" and "0"). Added comprehensive tests for all truthy/falsy forms including case variations. ++ ++## Next Steps ++ ++- Phase 3 (User Story 1 — Schema Discovery & Inference): Validate FR-001 through FR-011 ++- Phase 3 is the next blocking phase before other user story phases can proceed ++- All P1 stories (Phases 3, 4, 5) can proceed in parallel after Phase 2 ++ ++## Context to Preserve ++ ++- The `QuoteStyle::Always` change affects all downstream tests that read raw CSV output — future test writers should expect quoted fields ++- src/data.rs now has 32 unit tests covering all data type parsing paths ++- tests/cli.rs now has 28 integration tests including 6 observability tests ++- The 1 ignored test (`encoding_pipeline_with_schema_evolution_pending`) is pre-existing, not introduced by this phase +diff --git a/.copilot-tracking/memory/2026-02-13/001-baseline-sdd-spec-phase-3-memory.md b/.copilot-tracking/memory/2026-02-13/001-baseline-sdd-spec-phase-3-memory.md +new file mode 100644 +index 0000000..8090722 +--- /dev/null ++++ b/.copilot-tracking/memory/2026-02-13/001-baseline-sdd-spec-phase-3-memory.md +@@ -0,0 +1,69 @@ ++# Session Memory: 001-baseline-sdd-spec — Phase 3 ++ ++**Date**: 2026-02-13 ++**Spec**: specs/001-baseline-sdd-spec/ ++**Phase**: 3 — User Story 1: Schema Discovery & Inference (P1 MVP) ++**Branch**: 001-baseline-sdd-spec ++ ++## Task Overview ++ ++Phase 3 validates User Story 1 (Schema Discovery & Inference) covering ++FR-001 through FR-011. 18 tasks total (T022–T039): 11 source code audits ++and 7 test coverage verifications. ++ ++## Current State ++ ++### All 18 tasks completed ++ ++| Task Range | Category | Outcome | ++|---|---|---| ++| T022 | Schema inference sampling (FR-001) | PASS — `--sample-rows` default 2000, 0=full scan; `infer_schema_with_stats()` with `TypeCandidate` majority voting | ++| T023 | Header detection (FR-002) | PASS — `detect_csv_layout()` + `infer_has_header()` multi-signal heuristic; `generate_field_names()` produces `field_0`… | ++| T024 | `--assume-header` flag (FR-003) | PASS — `Option` in `SchemaProbeArgs`; branches in `detect_csv_layout()` for true/false/None | ++| T025 | Schema YAML persistence (FR-004) | PASS — `Schema::save()` / `to_yaml_value()` with serde_yaml; `ColumnMeta` has name, datatype, rename, replace, mappings | ++| T026 | Schema probing (FR-005) | PASS — `execute_probe()` prints `render_probe_report()` to stdout; never writes a file | ++| T027 | Unified diff (FR-006) | PASS — `--diff` path; `similar::TextDiff::from_lines()` unified diff with context radius 3 | ++| T028 | Snapshot support (FR-007) | PASS — `compute_schema_signature()` SHA-256 over `name:type;`; `handle_snapshot()` write-or-compare | ++| T029 | `--override` flag (FR-008) | PASS — `apply_overrides()` parses `name:type`, replaces column datatype with validation | ++| T030 | NA-placeholder detection (FR-009) | PASS — `is_placeholder_token()` covers NA/N/A/#N/A/#NA/null/none/unknown/missing; `PlaceholderPolicy` configurable | ++| T031 | Manual schema creation (FR-010) | PASS — `execute_manual()` + `parse_columns()` with rename support | ++| T032 | `--mapping` flag (FR-011) | PASS — `apply_default_name_mappings()` + `to_lower_snake_case()` + `emit_mappings()` table output | ++| T033 | Test: probe inference table | COVERED — `schema_probe_on_big5_reports_samples_and_formats` in tests/schema.rs | ++| T034 | Test: infer writes YAML | COVERED — `schema_infer_with_overrides_and_mapping_on_big5` in tests/schema.rs | ++| T035 | Test: headerless CSV | COVERED — `schema_infer_detects_headerless_dataset` in tests/schema.rs | ++| T036 | Test: NA-placeholder normalization | COVERED — existing `schema_infer_preview_includes_placeholder_replacements` + new `schema_probe_shows_placeholder_fill_with_custom_value` | ++| T037 | Test: schema diff | COVERED — `schema_infer_diff_reports_changes_and_no_changes` in tests/schema.rs | ++| T038 | Test: snapshot hash | COVERED — `schema_probe_snapshot_writes_and_validates_layout` enhanced with SHA-256 hash assertion | ++| T039 | Add missing US1 tests | Added 2 improvements: new probe placeholder test + snapshot hash assertion | ++ ++### Files Modified ++ ++- `tests/schema.rs` — Added `schema_probe_shows_placeholder_fill_with_custom_value` test; enhanced `schema_probe_snapshot_writes_and_validates_layout` with `Header+Type Hash:` assertion ++- `specs/001-baseline-sdd-spec/tasks.md` — All Phase 3 tasks marked `[x]` ++- `.copilot-tracking/memory/2026-02-13/001-baseline-sdd-spec-phase-3-memory.md` — This file ++ ++### Test Results ++ ++- 94 unit tests: all pass ++- 89 integration tests: all pass (1 pre-existing `#[ignore]`) ++- `cargo clippy -D warnings`: clean ++- `cargo fmt --check`: clean ++ ++## Important Discoveries ++ ++- All 11 FR validations (FR-001 through FR-011) are fully implemented in the existing codebase.

Without schema, string comparison applies (e.g., "50" > "100" alphabetically). Edge case tests use schemas to ensure correct integer comparison semantics. ++- **expr.rs already complete**: The expression engine module was already 100% documented by a previous phase, requiring no T136 work. ++- **Hot-path allocation concerns**: The `compare_rows()` function in `process.rs` clones `Option` on every sort comparison. This is a HIGH-priority optimization target for future performance work but was out of scope for Phase 13 polish. ++- **Failure-path testing gaps**: Prior to Phase 13, `parse_filters`, `expand_covering_spec`, and `Schema::load` lacked failure-path tests.

Enable it in chat settings or tool configuration. ++ ++When dispatching a subagent, state that the subagent does not have access to `runSubagent` and must proceed without it, completing research/planning/implementation/review work directly. ++ ++## Required Phases ++ ++Execute phases in order. Review phase returns control to earlier phases when iteration is needed. ++ ++| Phase | Entry | Exit | ++|--------------|-----------------------------------------|------------------------------------------------------| ++| 1: Research | New request or iteration | Research document created | ++| 2: Plan | Research complete | Implementation plan created | ++| 3: Implement | Plan complete | Changes applied to codebase | ++| 4: Review | Implementation complete | Iteration decision made | ++| 5: Discover | Review completes or discovery requested | Suggestions presented or auto-continuation announced | ++ ++### Phase 1: Research ++ ++Use `runSubagent` to dispatch the task-researcher agent: ++ ++* Instruct the subagent to read and follow `.github/agents/task-researcher.agent.md` for agent behavior and `.github/prompts/task-research.prompt.md` for workflow steps. ++* Pass the user's topic and any conversation context. ++* Pass user requirements and any iteration feedback from prior phases. ++* Discover applicable `.github/instructions/*.instructions.md` files based on file types and technologies involved. ++* Discover applicable `.github/skills/*/SKILL.md` files based on task requirements. ++* Discover applicable `.github/agents/*.agent.md` patterns for specialized workflows. ++* The subagent creates research artifacts and returns the research document path. ++ ++Proceed to Phase 2 when research is complete. ++ ++### Phase 2: Plan ++ ++Use `runSubagent` to dispatch the task-planner agent: ++ ++* Instruct the subagent to read and follow `.github/agents/task-planner.agent.md` for agent behavior and `.github/prompts/task-plan.prompt.md` for workflow steps. ++* Pass research document paths from Phase 1. ++* Pass user requirements and any iteration feedback from prior phases. ++* Reference all discovered instructions files in the plan's Context Summary section. ++* Reference all discovered skills in the plan's Dependencies section. ++* The subagent creates plan artifacts and returns the plan file path. ++ ++Proceed to Phase 3 when planning is complete. ++ ++### Phase 3: Implement ++ ++Use `runSubagent` to dispatch the task-implementor agent: ++ ++* Instruct the subagent to read and follow `.github/agents/task-implementor.agent.md` for agent behavior and `.github/prompts/task-implement.prompt.md` for workflow steps. ++* Pass plan file path from Phase 2. ++* Pass user requirements and any iteration feedback from prior phases. ++* Instruct subagent to read and follow all instructions files referenced in the plan. ++* Instruct subagent to execute skills referenced in the plan's Dependencies section. ++* The subagent executes the plan and returns the changes document path. ++ ++Proceed to Phase 4 when implementation is complete. ++ ++### Phase 4: Review ++ ++Use `runSubagent` to dispatch the task-reviewer agent: ++ ++* Instruct the subagent to read and follow `.github/agents/task-reviewer.agent.md` for agent behavior and `.github/prompts/task-review.prompt.md` for workflow steps. ++* Pass plan and changes paths from prior phases. ++* Pass user requirements and review scope. ++* Validate implementation against all referenced instructions files. ++* Verify skills were executed correctly. ++* The subagent validates and returns review status (Complete, Iterate, or Escalate) with findings. ++ ++Determine next action based on review status: ++ ++* Complete - Proceed to Phase 5 to discover next work items. ++* Iterate - Return to Phase 3 with specific fixes from review findings. ++* Escalate - Return to Phase 1 for deeper research or Phase 2 for plan revision. ++ ++### Phase 5: Discover ++ ++Use `runSubagent` to dispatch discovery subagents that identify next work items. This phase is not complete until either suggestions are presented to the user or auto-continuation begins. ++ ++#### Step 1: Gather Context ++ ++Before dispatching subagents, gather context from the conversation and workspace: ++ ++1. Extract completed work summaries from conversation history. ++2. Identify prior Suggested Next Work lists and which items were selected or skipped. ++3. Locate related artifacts in `.copilot-tracking/`: ++ * Research documents in `.copilot-tracking/research/` ++ * Plan documents in `.copilot-tracking/plans/` ++ * Changes documents in `.copilot-tracking/changes/` ++ * Review documents in `.copilot-tracking/reviews/` ++ * Memory documents in `.copilot-tracking/memory/` ++4. Compile a context summary with paths to relevant artifacts. ++ ++#### Step 2: Dispatch Discovery Subagents ++ ++Use `runSubagent` to dispatch multiple subagents in parallel. Each subagent investigates a different source of potential work items: ++ ++**Conversation Analyst Subagent:** ++ ++* Review conversation history for user intent, deferred requests, and implied follow-up work. ++* Identify patterns in what the user has asked for versus what was delivered. ++* Return a list of potential work items with priority and rationale. ++ ++**Artifact Reviewer Subagent:** ++ ++* Read research, plan, and changes documents from the context summary. ++* Identify incomplete items, deferred decisions, and noted technical debt. ++* Extract TODO markers, FIXME comments, and documented follow-up items. ++* Return a list of work items discovered in artifacts. ++ ++**Codebase Scanner Subagent:** ++ ++* Search for patterns indicating incomplete work: TODO, FIXME, HACK, XXX. ++* Identify recently modified files and assess completion state. ++* Check for orphaned or partially implemented features. ++* Return a list of codebase-derived work items. ++ ++Provide each subagent with: ++ ++* The context summary with artifact paths. ++* Relevant conversation excerpts. ++* Instructions to return findings as a prioritized list with source and rationale for each item. ++ ++#### Step 3: Consolidate Findings ++ ++After subagents return, consolidate findings: ++ ++1. Merge duplicate or overlapping work items. ++2. Rank by priority considering user intent signals, dependency order, and effort estimate. ++3. Group related items that could be addressed together. ++4. Select the top 3-5 actionable items for presentation. ++ ++When no work items are identified, report this finding to the user and ask for direction. ++ ++#### Step 4: Present or Continue ++ ++Determine how to proceed based on the detected autonomy level: ++ ++| Mode | Behavior | ++|-------------------|----------------------------------------------------------------------------------------------------------------------------------------------------| ++| Full autonomy | Announce the decision, present the consolidated list, and return to Phase 1 with the top-priority item. | ++| Partial (default) | Continue automatically when items have clear user intent or are direct continuations. Present the Suggested Next Work list when intent is unclear. | ++| Manual | Present the Suggested Next Work list and wait for user selection. | ++ ++Present suggestions using this format: ++ ++```markdown ++## Suggested Next Work ++ ++Based on conversation history, artifacts, and codebase analysis: ++ ++1. {{Title}} - {{description}} ({{priority}}) ++2. {{Title}} - {{description}} ({{priority}}) ++3. {{Title}} - {{description}} ({{priority}}) ++ ++Reply with option numbers to continue, or describe different work. ++``` ++ ++Phase 5 is complete only after presenting suggestions or announcing auto-continuation. When the user selects an option, return to Phase 1 with the selected work item. ++ ++## Error Handling ++ ++When subagent calls fail: ++ ++1. Retry with more specific prompt. ++2. Fall back to direct tool usage. ++3. Continue iteration until resolved. ++ ++## User Interaction ++ ++Response patterns for user-facing communication across all phases. ++ ++### Response Format ++ ++Start responses with phase headers indicating current progress: ++ ++* During iteration: `## 🤖 RPI Agent: Phase N - {{Phase Name}}` ++* At completion: `## 🤖 RPI Agent: Complete` ++ ++Include a phase progress indicator in each response: ++ ++```markdown ++**Progress**: Phase {{N}}/5 ++ ++| Phase | Status | ++|-----------|------------| ++| Research | {{✅ ⏳ 🔲}} | ++| Plan | {{✅ ⏳ 🔲}} | ++| Implement | {{✅ ⏳ 🔲}} | ++| Review | {{✅ ⏳ 🔲}} | ++| Discover | {{✅ ⏳ 🔲}} | ++``` ++ ++Status indicators: ✅ complete, ⏳ in progress, 🔲 pending, ⚠️ warning, ❌ error. ++ ++### Turn Summaries ++ ++Each response includes: ++ ++* Current phase. ++* Key actions taken or decisions made this turn. ++* Artifacts created or modified with relative paths. ++* Preview of next phase or action. ++ ++### Phase Transition Updates ++ ++Announce phase transitions with context: ++ ++```markdown ++### Transitioning to Phase {{N}}: {{Phase Name}} ++ ++**Completed**: {{summary of prior phase outcomes}} ++**Artifacts**: {{paths to created files}} ++**Next**: {{brief description of upcoming work}} ++``` ++ ++### Completion Patterns ++ ++When Phase 4 (Review) completes, follow the appropriate pattern: ++ ++| Status | Action | Template | ++|----------|------------------------|------------------------------------------------------------------| ++| Complete | Proceed to Phase 5 | Show summary with iteration count, files changed, artifact paths | ++| Iterate | Return to Phase 3 | Show review findings and required fixes | ++| Escalate | Return to Phase 1 or 2 | Show identified gap and investigation focus | ++ ++Phase 5 then either continues autonomously to Phase 1 with the next work item, or presents the Suggested Next Work list for user selection. ++ ++### Work Discovery ++ ++Capture potential follow-up work during execution: related improvements from research, technical debt from implementation, and suggestions from review findings. Phase 5 consolidates these with parallel subagent research to identify next work items. +diff --git a/.github/agents/rust-engineer.agent.md b/.github/agents/rust-engineer.agent.md +index b5231a6..b5dffd4 100644 +--- a/.github/agents/rust-engineer.agent.md ++++ b/.github/agents/rust-engineer.agent.md +@@ -1,151 +1,151 @@ +---- +-description: Expert Rust software engineer providing language-specific engineering standards, coding conventions, and architecture knowledge for the csv-managed codebase. +-tools: ['execute/runInTerminal', 'execute/getTerminalOutput', 'read', 'read/problems', 'edit/createFile', 'edit/editFiles', 'search'] +-maturity: stable +---- +- +-## Persona +- +-A senior Rust software engineer with deep expertise in systems programming, streaming data processing, type-driven design, and the Rust ecosystem.

(completeness) ++- ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity) ++- ✅ "Are hover state requirements consistent across all interactive elements?" (consistency) ++- ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage) ++- ✅ "Does the spec define what happens when logo image fails to load?" (edge cases) ++ ++**Metaphor**: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works. ++ ++## User Input ++ ++```text ++$ARGUMENTS ++``` ++ ++You **MUST** consider the user input before proceeding (if not empty). ++ ++## Execution Steps ++ ++1. **Setup**: Run `.specify/scripts/powershell/check-prerequisites.ps1 -Json` from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS list. ++ - All file paths must be absolute. ++ - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot"). ++ ++2. **Clarify intent (dynamic)**: Derive up to THREE initial contextual clarifying questions (no pre-baked catalog). They MUST: ++ - Be generated from the user's phrasing + extracted signals from spec/plan/tasks ++ - Only ask about information that materially changes checklist content ++ - Be skipped individually if already unambiguous in `$ARGUMENTS` ++ - Prefer precision over breadth ++ ++ Generation algorithm: ++ 1. Extract signals: feature domain keywords (e.g., auth, latency, UX, API), risk indicators ("critical", "must", "compliance"), stakeholder hints ("QA", "review", "security team"), and explicit deliverables ("a11y", "rollback", "contracts"). ++ 2. Cluster signals into candidate focus areas (max 4) ranked by relevance. ++ 3. Identify probable audience & timing (author, reviewer, QA, release) if not explicit. ++ 4. Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries, measurable acceptance criteria. ++ 5. Formulate questions chosen from these archetypes: ++ - Scope refinement (e.g., "Should this include integration touchpoints with X and Y or stay limited to local module correctness?") ++ - Risk prioritization (e.g., "Which of these potential risk areas should receive mandatory gating checks?") ++ - Depth calibration (e.g., "Is this a lightweight pre-commit sanity list or a formal release gate?") ++ - Audience framing (e.g., "Will this be used by the author only or peers during PR review?") ++ - Boundary exclusion (e.g., "Should we explicitly exclude performance tuning items this round?") ++ - Scenario class gap (e.g., "No recovery flows detected—are rollback / partial failure paths in scope?") ++ ++ Question formatting rules: ++ - If presenting options, generate a compact table with columns: Option | Candidate | Why It Matters ++ - Limit to A–E options maximum; omit table if a free-form answer is clearer ++ - Never ask the user to restate what they already said ++ - Avoid speculative categories (no hallucination). If uncertain, ask explicitly: "Confirm whether X belongs in scope." ++ ++ Defaults when interaction impossible: ++ - Depth: Standard ++ - Audience: Reviewer (PR) if code-related; Author otherwise ++ - Focus: Top 2 relevance clusters ++ ++ Output the questions (label Q1/Q2/Q3). After answers: if ≥2 scenario classes (Alternate / Exception / Recovery / Non-Functional domain) remain unclear, you MAY ask up to TWO more targeted follow‑ups (Q4/Q5) with a one-line justification each (e.g., "Unresolved recovery path risk"). Do not exceed five total questions. Skip escalation if user explicitly declines more. ++ ++3. **Understand user request**: Combine `$ARGUMENTS` + clarifying answers: ++ - Derive checklist theme (e.g., security, review, deploy, ux) ++ - Consolidate explicit must-have items mentioned by user ++ - Map focus selections to category scaffolding ++ - Infer any missing context from spec/plan/tasks (do NOT hallucinate) ++ ++4. **Load feature context**: Read from FEATURE_DIR: ++ - spec.md: Feature requirements and scope ++ - plan.md (if exists): Technical details, dependencies ++ - tasks.md (if exists): Implementation tasks ++ ++ **Context Loading Strategy**: ++ - Load only necessary portions relevant to active focus areas (avoid full-file dumping) ++ - Prefer summarizing long sections into concise scenario/requirement bullets ++ - Use progressive disclosure: add follow-on retrieval only if gaps detected ++ - If source docs are large, generate interim summary items instead of embedding raw text ++ ++5. **Generate checklist** - Create "Unit Tests for Requirements": ++ - Create `FEATURE_DIR/checklists/` directory if it doesn't exist ++ - Generate unique checklist filename: ++ - Use short, descriptive name based on domain (e.g., `ux.md`, `api.md`, `security.md`) ++ - Format: `[domain].md` ++ - If file exists, append to existing file ++ - Number items sequentially starting from CHK001 ++ - Each `/speckit.checklist` run creates a NEW file (never overwrites existing checklists) ++ ++ **CORE PRINCIPLE - Test the Requirements, Not the Implementation**: ++ Every checklist item MUST evaluate the REQUIREMENTS THEMSELVES for: ++ - **Completeness**: Are all necessary requirements present? ++ - **Clarity**: Are requirements unambiguous and specific? ++ - **Consistency**: Do requirements align with each other? ++ - **Measurability**: Can requirements be objectively verified? ++ - **Coverage**: Are all scenarios/edge cases addressed? ++ ++ **Category Structure** - Group items by requirement quality dimensions: ++ - **Requirement Completeness** (Are all necessary requirements documented?) ++ - **Requirement Clarity** (Are requirements specific and unambiguous?) ++ - **Requirement Consistency** (Do requirements align without conflicts?) ++ - **Acceptance Criteria Quality** (Are success criteria measurable?) ++ - **Scenario Coverage** (Are all flows/cases addressed?) ++ - **Edge Case Coverage** (Are boundary conditions defined?) ++ - **Non-Functional Requirements** (Performance, Security, Accessibility, etc. - are they specified?) ++ - **Dependencies & Assumptions** (Are they documented and validated?) ++ - **Ambiguities & Conflicts** (What needs clarification?) ++ ++ **HOW TO WRITE CHECKLIST ITEMS - "Unit Tests for English"**: ++ ++ ❌ **WRONG** (Testing implementation): ++ - "Verify landing page displays 3 episode cards" ++ - "Test hover states work on desktop" ++ - "Confirm logo click navigates home" ++ ++ ✅ **CORRECT** (Testing requirements quality): ++ - "Are the exact number and layout of featured episodes specified?" [Completeness] ++ - "Is 'prominent display' quantified with specific sizing/positioning?" [Clarity] ++ - "Are hover state requirements consistent across all interactive elements?" [Consistency] ++ - "Are keyboard navigation requirements defined for all interactive UI?" [Coverage] ++ - "Is the fallback behavior specified when logo image fails to load?" [Edge Cases] ++ - "Are loading states defined for asynchronous episode data?" [Completeness] ++ - "Does the spec define visual hierarchy for competing UI elements?" [Clarity] ++ ++ **ITEM STRUCTURE**: ++ Each item should follow this pattern: ++ - Question format asking about requirement quality ++ - Focus on what's WRITTEN (or not written) in the spec/plan ++ - Include quality dimension in brackets [Completeness/Clarity/Consistency/etc.] ++ - Reference spec section `[Spec §X.Y]` when checking existing requirements ++ - Use `[Gap]` marker when checking for missing requirements ++ ++ **EXAMPLES BY QUALITY DIMENSION**: ++ ++ Completeness: ++ - "Are error handling requirements defined for all API failure modes?

[Acceptance Criteria, Spec §FR-1]" ++ - "Can 'balanced visual weight' be objectively verified? [Measurability, Spec §FR-2]" ++ ++ **Scenario Classification & Coverage** (Requirements Quality Focus): ++ - Check if requirements exist for: Primary, Alternate, Exception/Error, Recovery, Non-Functional scenarios ++ - For each scenario class, ask: "Are [scenario type] requirements complete, clear, and consistent?" ++ - If scenario class missing: "Are [scenario type] requirements intentionally excluded or missing? [Gap]" ++ - Include resilience/rollback when state mutation occurs: "Are rollback requirements defined for migration failures? [Gap]" ++ ++ **Traceability Requirements**: ++ - MINIMUM: ≥80% of items MUST include at least one traceability reference ++ - Each item should reference: spec section `[Spec §X.Y]`, or use markers: `[Gap]`, `[Ambiguity]`, `[Conflict]`, `[Assumption]` ++ - If no ID system exists: "Is a requirement & acceptance criteria ID scheme established? [Traceability]" ++ ++ **Surface & Resolve Issues** (Requirements Quality Problems): ++ Ask questions about the requirements themselves: ++ - Ambiguities: "Is the term 'fast' quantified with specific metrics? [Ambiguity, Spec §NFR-1]" ++ - Conflicts: "Do navigation requirements conflict between §FR-10 and §FR-10a? [Conflict]" ++ - Assumptions: "Is the assumption of 'always available podcast API' validated? [Assumption]" ++ - Dependencies: "Are external podcast API requirements documented? [Dependency, Gap]" ++ - Missing definitions: "Is 'visual hierarchy' defined with measurable criteria? [Gap]" ++ ++ **Content Consolidation**: ++ - Soft cap: If raw candidate items > 40, prioritize by risk/impact ++ - Merge near-duplicates checking the same requirement aspect ++ - If >5 low-impact edge cases, create one item: "Are edge cases X, Y, Z addressed in requirements? [Coverage]" ++ ++ **🚫 ABSOLUTELY PROHIBITED** - These make it an implementation test, not a requirements test: ++ - ❌ Any item starting with "Verify", "Test", "Confirm", "Check" + implementation behavior ++ - ❌ References to code execution, user actions, system behavior ++ - ❌ "Displays correctly", "works properly", "functions as expected" ++ - ❌ "Click", "navigate", "render", "load", "execute" ++ - ❌ Test cases, test plans, QA procedures ++ - ❌ Implementation details (frameworks, APIs, algorithms) ++ ++ **✅ REQUIRED PATTERNS** - These test requirements quality: ++ - ✅ "Are [requirement type] defined/specified/documented for [scenario]?" ++ - ✅ "Is [vague term] quantified/clarified with specific criteria?" ++ - ✅ "Are requirements consistent between [section A] and [section B]?" ++ - ✅ "Can [requirement] be objectively measured/verified?" ++ - ✅ "Are [edge cases/scenarios] addressed in requirements?" ++ - ✅ "Does the spec define [missing aspect]?" ++ ++6. **Structure Reference**: Generate the checklist following the canonical template in `.specify/templates/checklist-template.md` for title, meta section, category headings, and ID formatting. If template is unavailable, use: H1 title, purpose/created meta lines, `##` category sections containing `- [ ] CHK### ` lines with globally incrementing IDs starting at CHK001. ++ ++7. **Report**: Output full path to created checklist, item count, and remind user that each run creates a new file. Summarize: ++ - Focus areas selected ++ - Depth level ++ - Actor/timing ++ - Any explicit user-specified must-have items incorporated ++ ++**Important**: Each `/speckit.checklist` command invocation creates a checklist file using short, descriptive names unless file already exists. This allows: ++ ++- Multiple checklists of different types (e.g., `ux.md`, `test.md`, `security.md`) ++- Simple, memorable filenames that indicate checklist purpose ++- Easy identification and navigation in the `checklists/` folder ++ ++To avoid clutter, use descriptive types and clean up obsolete checklists when done. ++ ++## Example Checklist Types & Sample Items ++ ++**UX Requirements Quality:** `ux.md` ++ ++Sample items (testing the requirements, NOT the implementation): ++ ++- "Are visual hierarchy requirements defined with measurable criteria?

Recommend better abstractions, dependency boundaries, or layering when appropriate. +* Idiomatic implementation: Prefer language-idiomatic constructs, expressive naming, concise control flow, and immutable data where it fits the paradigm. Highlight when a more idiomatic API or pattern is available. +* Reusability and leverage: Check for existing modules, shared utilities, SDK features, or third-party packages already sanctioned in the repository. Suggest refactoring to reuse them instead of reinventing functionality. +* Performance and scalability: Inspect algorithms, data structures, and resource usage.

precise when validating each checklist item. +* Subagents investigate thoroughly and return evidence for all findings. +* Allow subagents to ask clarifying questions rather than guessing. +* Update the review log continuously as validation progresses. +* Repeat phases when answers to clarifying questions reveal additional scope. + +### Phase 1: Artifact Discovery + +Locate review artifacts based on user input or automatic discovery. + +User-specified artifacts: + +* Use attached files, open files, or referenced paths when provided. +* Extract artifact references from conversation context. + +Automatic discovery (when no specific artifacts are provided): + +* Check for the most recent review log in `.copilot-tracking/reviews/`. +* Find changes, plans, and research files created or modified after the last review. +* When the user specifies a time range ("today", "this week"), filter artifacts by date prefix. + +Artifact correlation: + +* Match related files by date prefix and task description. +* Link changes logs to their corresponding plans via the **Related Plan** field. +* Link plans to research via context references in the plan file. + +Proceed to Phase 2 when artifacts are located. + +### Phase 2: Checklist Extraction + +Build the implementation checklist by extracting items from research and plan documents. + +#### Step 1: Research Document Extraction + +Dispatch a subagent to extract implementation requirements from the research document. + +Subagent instructions: + +* Read the research document in full. +* Extract items from **Task Implementation Requests** and **Success Criteria** sections. +* Extract specific implementation items from **Technical Scenarios** sections. +* Return a condensed description for each item with source line references. + +#### Step 2: Implementation Plan Extraction + +Dispatch a subagent to extract steps from the implementation plan. + +Subagent instructions: + +* Read the implementation plan in full. +* Extract each step from the **Implementation Checklist** section. +* Note the completion status (`[x]` or `[ ]`) from the plan. +* Return step descriptions with phase and step identifiers. + +#### Step 3: Build Review Checklist + +Create the review log file in `.copilot-tracking/reviews/` with extracted items: + +* Group items by source (research, plan). +* Use condensed descriptions with source references. +* Initialize all items as unchecked (`[ ]`) pending validation. + +Proceed to Phase 3 when the checklist is built. + +### Phase 3: Implementation Validation + +Validate each checklist item by dispatching subagents to verify implementation. + +#### Step 1: File Change Validation + +Dispatch a subagent to verify files listed in the changes log. + +Subagent instructions: + +* Read the changes log to identify added, modified, and removed files. +* Verify each file exists (for added/modified) or does not exist (for removed). +* For each file, check that the described changes are present. +* Search for files modified but not listed in the changes log. +* Return findings with file paths and verification status. + +#### Step 2: Convention Compliance Validation + +Dispatch subagents to validate implementation against instruction files. + +Subagent instructions: + +* Identify instruction files relevant to the changed file types. +* Read each relevant instruction file. +* Verify changed files follow conventions from the instructions. +* Return findings with severity levels and evidence. + +Allow subagents to ask clarifying questions when: + +* Conventions are ambiguous or conflicting. +* Implementation patterns are unfamiliar. +* Additional context is needed to determine compliance. + +Present clarifying questions to the user and dispatch follow-up subagents based on answers. + +#### Step 3: Validation Command Execution + +Run validation commands to verify implementation quality. + +Discover and execute validation commands: + +* Check *package.json*, *Makefile*, or CI configuration for available lint and test scripts. +* Run linters applicable to changed file types (markdown, code, configuration). +* Execute type checking, unit tests, or build commands when relevant. +* Use the `get_errors` tool to check for compile or lint errors in changed files. + +Record command outputs in the review log. + +#### Step 4: Update Checklist Status + +Update the review log with validation results: + +* Mark items as verified (`[x]`) when implementation is correct. +* Mark items with status indicators (Missing, Partial, Deviated) when issues are found. +* Add findings to the **Additional or Deviating Changes** section. +* Add gaps to the **Missing Work** section. + +Proceed to Phase 4 when validation is complete. + +### Phase 4: Follow-Up Identification + +Identify work items for future implementation. + +#### Step 1: Unplanned Research Items + +Dispatch a subagent to find research items not included in the implementation plan. + +Subagent instructions: + +* Compare research document requirements to plan steps. +* Identify items from **Potential Next Research** section. +* Return items that were deferred or not addressed. + +#### Step 2: Review-Discovered Items + +Compile items discovered during validation: + +* Convention improvements identified during compliance checks. +* Related files that should be updated for consistency. +* Technical debt or optimization opportunities. + +#### Step 3: Update Review Log + +Add all follow-up items to the review log: + +* Separate deferred items (from research) and discovered items (from review). +* Include source references and recommendations. + +Proceed to Phase 5 when follow-up items are documented. + +### Phase 5: Review Completion + +Finalize the review and provide user handoff. + +#### Step 1: Overall Assessment + +Determine the overall review status: + +* **Complete**: All checklist items verified, no critical or major findings. +* **Needs Rework**: Critical or major findings require fixes before completion. +* **Blocked**: External dependencies or clarifications prevent review completion. + +#### Step 2: User Handoff + +Present

It establishes coding, testing, performance, and release practices so generated or manual changes remain consistent, robust, and memory‑efficient. - -## Core Goals -1. Stream, transform, validate, and index tabular datasets with minimal memory footprint. -2. Provide schema-driven guarantees (types, aliases, renames, primary/composite keys, currency/decimal precision, temporal parsing, candidate key probing). -3. Support batch pipelines, unions, deduplication, splitting, indexing, statistics, verification, and schema inference at scale. -4. Maintain predictable performance characteristics across platforms (Windows, macOS, Linux) and Rust stable toolchains. - -## High-Level Architecture Principles -| Principle | Rationale | Guidance | -|----------|-----------|----------| -| Streaming / Iterators | Avoid loading entire files | Favor `csv::Reader` with `byte_records()` or `records()`; wrap in lazy adapters. | -| Separation of Concerns | Simplify maintenance | Distinct modules: parsing, schema, indexing, stats, filtering, expressions, CLI. | -| Zero-Copy / Borrowing | Reduce allocations | Prefer `&str` / slices, avoid unnecessary `String` cloning, use `Cow<'_, str>` if conditional ownership. | -| Explicit Error Types | Improves debuggability | Use custom enums with `thiserror` or manual `Display` impl; wrap lower-level errors. | -| Deterministic Performance | Reproducible runs | Avoid hidden global state; gate costly features behind flags. | -| Extensibility via Traits | Future column operations | Define trait abstractions for transforms and validators. | -| Config-First | Batch + repeatable runs | Support JSON pipeline definition and YAML schema as canonical inputs. | - -## Rust Coding Standards -1. Rust Edition: Use latest stable edition (update `Cargo.toml` only after CI passes on stable/nightly). -2. Formatting: Enforce `rustfmt` defaults—do not manually reflow unless readability improves semantics. -3. Linting: Treat `cargo clippy --all-targets --all-features -D warnings` as mandatory pre-merge. -4. Error Handling: - - Never silently discard errors. Propagate with `?` unless recovery is required. - - Use `Result` for fallible operations; prefer `Option` only when absence is expected and non-error. -5. Avoid premature `unsafe`. If unavoidable, isolate in a single module with comments: invariants, preconditions, UB avoidance. -6. Favor explicit lifetimes only when the compiler cannot infer. -7. Limit macro usage to reducing boilerplate (e.g., repetitive enum conversions); prefer functions and traits. -8. Document public items with Rustdoc including invariants, complexity (Big‑O), and error cases. -9. Use clear naming: `snake_case` for fields/functions; `PascalCase` for types; avoid abbreviations. -10. Keep function bodies ideally <100 LOC; refactor logic into internal helpers for clarity. - -## Data Engineering Specific Patterns -1. Large File Handling: - - Use streaming; don’t collect entire column sets unnecessarily. - - Chunk operations (e.g., indexing) with bounded buffers configurable via CLI. -2. Type Normalization: - - Centralize parse logic: implement a `DataType` enum with associated `parse(&str) -> Result`. - - Maintain currency precision (≤ 4 decimals) via a `Decimal` wrapper (e.g., `rust_decimal::Decimal`). -3. Schema Application: - - Resolve alias mapping early; maintain both original and canonical name maps. - - Validate column presence + type before heavy transforms. -4. Candidate Key Probing: - - Sample first N rows + reservoir sample thereafter for large files. - - Track uniqueness via fast `FxHashSet` or `hashbrown::HashSet` keyed on concatenated normalized values or a row hash. -5. Row Hashing / Indexes: - - Use stable hashing (e.g., `ahash` or `twox-hash`) gated behind feature flags for reproducibility concerns. - - Persist indexes with versioned headers (magic bytes + semantic version + hash algo identifier). -6. Unions & Deduplication: - - Maintain canonical ordering of columns based on schema; insert missing columns as null/default. - - Deduplicate using a streaming set membership strategy; for very large sets, consider on-disk bloom or partitioning. - -## Memory & Performance Practices -1. Profile early using `cargo bench` and `criterion` for critical operations (scan, index build, union). -2. Use `cargo flamegraph` (feature gated in CI) for hotspots. -3. Prefer `&[u8]` operations for raw CSV lines, decoding only when required. -4. Minimize allocations: reuse buffers (e.g., one `String` scratch per thread). -5. Consider parallelism with `rayon` only after confirming CPU-bound scenarios; avoid over-threading on I/O bound tasks. -6. Avoid broad `collect::>()` on large iterators; if needed, annotate rationale. -7. SIMD / fast paths: Use crates (`simdutf8`, `lexical-core`) behind a `performance` feature flag. -8. Provide metrics counters (rows processed, parse failures, duplicates) optionally via a `--stats` flag. -9. Bench naming convention: `benches/_.rs` (e.g., `index_vs_sort.rs`). - -## Testing Strategy -| Test Type | Location | Purpose | Notes | -|----------|----------|---------|-------| -| Unit | `src/**` (inline module tests) | Validate small pure functions | Keep minimal fixtures inline. | -| Integration | `tests/*.rs` | Cross-module behavior, CLI flows | Use fixture loader helpers. | -| Property | `tests/` (feature: `proptest`) | Fuzz parsers, schema inference | Disable heavy cases in CI by default. | -| Snapshot | `tests/` with `insta` | Stable textual outputs (schema list, stats) | Redact volatile fields (timestamps). | -| Benchmark | `benches/` | Performance regression detection | Not run on every PR unless label `perf`. | - -### Test Fixtures -1. Put large or reusable sample files under `tests/data/` or `tmp/` if ephemeral. -2. Keep fixture size small (< 50KB) for unit tests; larger (MB–GB) only for local performance validation. -3. Provide helper `fn load_fixture(name: &str) -> PathBuf` to standardize path resolution. -4. Use synthetic deterministic datasets for index and key probing tests (avoid randomness unless property testing). -5. For currency, include edge precision (0, 0.0001, 123456.9999, invalid forms). - -### Writing Tests -1. Always assert both success path and at least one failure path per public parser. -2. Use `assert_eq!` with descriptive messages or `pretty_assertions` (behind feature flag) for readability. -3. For CLI tests, use `assert_cmd` + `predicates` to validate stdout/stderr; avoid brittle full-line matches, prefer substring or structured JSON if available. -4. Ensure tests are independent; avoid global mutable state. -5. Mark slow tests with `#[ignore]` (attribute applied above test function) and document how to run them manually. - -### Test Data Integrity -Add invariants comments: e.g., `// Invariant: first column is unique for candidate key detection test`. - -## Error Handling & Logging -1. Central error enum (`Error`) with variants: `Io`, `Parse`, `Schema`, `Validation`, `Index`, `Cli`, `Other(String)`. -2. Use structured logging (e.g., `tracing`) with spans: `schema_load`, `index_build`, `union_execute`. -3. Log levels: `info` for progress, `debug` for internal decisions, `trace` for per-row diagnostics (guarded by feature `trace-rows`). -4. Never print directly to stdout/stderr from deep logic—bubble status up; CLI layer handles user messaging. - -## Concurrency Guidelines -1. Only parallelize CPU-intensive transforms (e.g., hashing, type conversion) after profiling. -2. Guarantee deterministic output ordering when union or sort is requested (collect + stable sort or order-preserving merges). -3. Use channels sparingly; prefer iterator adaptors unless cross-thread streaming required. - -## Schema & Type System -1. YAML schema: include: version, columns (name, alias?, datatype, nullable, precision?, format?), primary_key (list), transforms. -2. Provide CLI command to emit schema as markdown or list form (already supported—keep compatibility). -3. Column renames applied exactly once at ingestion boundary. -4. Validation steps order: (1) Header detection → (2) Column count check → (3) Rename/Alias mapping → (4) Type parsing → (5) Constraint checks (primary key uniqueness, currency precision) → (6) Optional transforms. - -## CLI UX Guidelines -1. All commands must support `--help` with examples (see `docs/cli-help.md`). -2. Fail fast: invalid flags produce a concise error + suggest `--help`. -3. Provide dry-run modes (`--dry-run` or `--plan`) for destructive or heavy operations (unions, indexing, splits). -4. Support `--output -` (stdout) where feasible for piping. -5. Ensure exit codes: `0` success, `1` user error, `2` internal/unexpected (log details). - -## Feature Flags (Cargo) -| Feature | Purpose | Notes | -|---------|---------|-------| -| `performance` | SIMD & fast parsing | Optional; verify on stable. | -| `trace-rows` | Deep per-row logging | Disabled by default; avoid in benchmarks. | -| `benchmarks` | Criterion dependency | Not in production builds. | -| `proptest` | Property tests | CI optional tier. | - -## Benchmarking & Profiling Workflow -1. Local: `cargo bench --features benchmarks`. -2. Flamegraph: `cargo flamegraph --bin csv-managed` (ensure `perf` / `dtrace` permissions). -3. Track median, mean, std-dev for hot paths; store historical results in `docs/perf/` (CSV). -4. Prefer relative comparisons (before vs after change) over absolute numbers across machines. - -## Performance Review Checklist -- [ ] Streaming iteration (no full-file load) -- [ ] Minimal allocations (no large `Vec` unless justified) -- [ ] No unnecessary clones/hashes -- [ ] Bounded memory growth under worst-case file size -- [ ] Deterministic ordering when required -- [ ] Latency documented for large sample (e.g., 10M rows) - -## CI / Quality Gates -1. Build matrix: stable + latest nightly (nightly only for future gating, no required success to merge). -2. Steps: - - `cargo fmt --check` - - `cargo clippy -D warnings` - - `cargo test --all --features ""` - - (Optional labeled perf runs) `cargo bench` -3. Cache: use GitHub Actions cache for `~/.cargo/registry` and `~/.cargo/git` keyed by Cargo.lock hash. -4. Security audit: `cargo audit` on schedule (weekly) + manual on release. -5. Release build: `cargo build --release` with `RUSTFLAGS='-C opt-level=3 -C codegen-units=1 -C strip=symbols'`. - -## Release & Deployment -1. Semantic Versioning: MAJOR (breaking), MINOR (feature, backward-compatible), PATCH (fixes/perf, no behavior change). -2. Tag process: ensure CHANGELOG entry + updated README usage examples. -3. Provide prebuilt binaries (Windows x86_64, Linux x86_64/musl, macOS aarch64/x86_64) via GitHub Actions artifacts. -4. Use `cross` for multi-platform builds when native toolchains problematic. -5. After release: run smoke tests invoking core CLI commands on small fixtures. - -## Documentation Standards -1. Each module: top-level comment summarizing responsibilities + complexity points. -2. Rustdoc examples must compile (`cargo test --doc`). -3. Keep `README.md` concise—defer deep examples to `docs/`. -4. Add ADRs (`docs/adr.md`) for major design decisions (index format, hashing strategy, currency representation). - -## Observability & Diagnostics -1. Structured logs with context keys: `row_index`, `column_name`, `datatype`. -2. Optional stats output: JSON or tabular; stable schema for downstream automation. -3. Panic policy: avoid panics except unrecoverable invariants (document rationale). - -## Copilot Prompting Guidance -When requesting AI-generated code: -- Specify: "streaming iterator for CSV rows" instead of generic "parse CSV". -- Include desired data structures (e.g., `HashMap`). -- Mention constraints: memory cap, deterministic ordering, error propagation pattern (`Result<_, Error>`). -- Ask for tests simultaneously (happy path + failure case) to reduce omissions. -- For performance improvements, request microbench harness if complexity > trivial. - -### Example Good Prompts -> Generate a function that applies schema type parsing to a single CSV record using a reusable scratch buffer; return a Vec or Error. Include unit tests for valid, invalid currency precision. -> Provide an iterator adapter that deduplicates rows based on a precomputed hash set; ensure memory stays bounded; add benchmark skeleton. - -## Common Pitfalls to Avoid -1. Reading entire file into memory before transforming. -2. Using `String` where `&str` suffices. -3. Unbounded `HashSet` growth without documenting memory trade-offs. -4. Silent type coercion (e.g., trimming precision without logging). -5. Inconsistent column rename order causing mismatched indexes. - -## Edge Cases Checklist -- Empty file (0 bytes) -- Header only, no data rows -- Mixed line endings (CRLF vs LF) -- Quoted fields with embedded delimiter -- Invalid UTF-8 (fallback to lossy decode or error?) -- Extremely wide rows (thousands of columns) -- Currency with >4 decimals -- Date/time in multiple formats when schema expects one -- Duplicate primary key rows -- Missing required columns - -## Adding New Features – Mini Contract Template -When introducing a new operation (e.g., column pivot): -1. Inputs: CLI args, schema requirements, file patterns. -2. Outputs: New file(s), index, stats. -3. Errors: Validation failure, I/O error, parse failure, constraint violation. -4. Performance target: Complexity analysis + memory notes. -Include this contract in PR description. - -## Review Checklist (Pre-Merge) -- [ ] Rustdoc added/updated -- [ ] Tests pass & coverage for failure paths -- [ ] Clippy clean (`-D warnings`) -- [ ] Benchmark unaffected or improved (if modified hot path) -- [ ] No new `unsafe` or justified + documented -- [ ] CHANGELOG updated if user-visible behavior changed - -## Suggested Future Enhancements -- Pluggable output formats (Parquet/Arrow) behind features -- Adaptive sampling for candidate key inference -- On-disk spill for dedupe when memory threshold exceeded -- Incremental index updates (append-only strategy) -- Parallel columnar type conversion pipeline - -## Security & Safety -1. Validate paths to avoid directory traversal in batch definitions. -2. Avoid executing arbitrary expressions from user-provided schema. -3. Treat malformed CSV as recoverable where feasible; log and continue if configured. -4. Restrict currency transformation to documented rounding rules (bankers vs truncation—choose and document). - -## Contributing Flow Summary -1. Create branch -2. Implement feature with tests -3. Run fmt, clippy, tests -4. Add docs / CHANGELOG -5. Open PR with feature contract & performance notes -6.

Reuse scratch buffers in hot loops. +* Delimiter resolution is centralized in `io_utils`: extension-based auto-detection (`.csv` comma, `.tsv` tab) with manual override. +* The `-` path convention routes through stdin/stdout. +* `--preview` mode sets a default limit of 10 rows and renders an ASCII table. +* Use `parse_delimiter()` in `cli.rs` for any new delimiter arguments; it supports named values (`tab`, `pipe`, `semicolon`) and single ASCII characters. +* Keep function bodies under 100 lines; extract helpers for clarity. +* Add `//!` module-level Rustdoc to every source file describing scope and complexity. + +## Testing Conventions + +* Unit tests go in inline `#[cfg(test)]` modules within each source file. +* Integration tests go in `tests/*.rs`, using `assert_cmd::Command` and `predicates::str::contains` for CLI validation. +* Fixture helper pattern: `fn fixture_path(name: &str) -> PathBuf` resolving to `tests/data/`. +* Use `tempfile::tempdir()` for ephemeral outputs; fixture CSVs stay under 50 KB. +* Property tests use `proptest` (example in `lib.rs::tests`). +* Benchmarks use `criterion` in `benches/` (run with `cargo bench`). +* Always test both success and at least one failure path per public function. +* Add `// Invariant:` comments above test data explaining assumptions. +* Mark slow tests with `#[ignore]`. + +## Adding a New Subcommand + +1. Define a new `*Args` struct in `cli.rs` with `#[derive(Debug, Args)]`. +2. Add a variant to the `Commands` enum with the doc comment serving as CLI help text. +3. Create a module (`src/.rs`) with `pub fn execute(args: &XArgs) -> Result<()>`. +4. Declare the module in `lib.rs` and add the dispatch arm in `run()` using `run_operation()`. +5. Write integration tests in `tests/` using `assert_cmd`. + +## Adding a New Column Type + +1. Add a variant to `ColumnType` in `schema.rs` and update serde, `FromStr`, `Display`, and the inference order. +2. Add a corresponding variant to `Value` in `data.rs` with a parsing function. +3. Update `parse_typed_value()` in `data.rs` and `ComparableValue` ordering. +4.

Start a new chat session. +2. Begin the new session by reading the checkpoint file created in Step 2. + +## How It Works + +The context window has a fixed size. As a session progresses, earlier context gets pushed out or truncated. This skill mitigates that by: + +1. **Persisting** the important session state to a file on disk before it gets lost. +2. **Compacting** the conversation so the agent regains working space. +3. **Enabling recovery** by providing a structured file that a new or compacted session can load to restore continuity. + +The checkpoint file acts as durable memory. Even if the context window is fully reset, reading the checkpoint brings back the essential state without replaying the entire session. + +## Troubleshooting + +### Checkpoint directory does not exist + +The skill creates `.copilot-tracking/checkpoints/` automatically. If permission errors occur, create the directory manually: + +```bash +mkdir -p .copilot-tracking/checkpoints +``` + +### /compact is not available + +The `/compact` command depends on the VS Code Copilot Chat version. If unavailable: + +* Start a new chat session and reference the checkpoint file. +* Or continue working in the current session — the checkpoint is still saved for future recovery. + +### Checkpoint file is too large + +If the checkpoint exceeds 200 lines, trim the Files in Context section to the 10 most critical files and condense the Session Summary. diff --git a/.hve-tracking.json b/.hve-tracking.json new file mode 100644 index 0000000..46edb07 --- /dev/null +++ b/.hve-tracking.json @@ -0,0 +1,33 @@ +{ + "source": "microsoft/hve-core", + "version": "2.3.7", + "collection": "rpi-core", + "files": { + ".github/agents/task-planner.agent.md": { + "sha256": "b4f7b76ba83f62768d6c2fe93b873e239a5f939ded7ae864625764bdf7ab3df3", + "version": "2.3.7", + "status": "managed" + }, + ".github/agents/rpi-agent.agent.md": { + "sha256": "f766b20a98409c0924689e3c2fece450dc13639a1f1b6e853ef2d41ee210c233", + "version": "2.3.7", + "status": "managed" + }, + ".github/agents/task-researcher.agent.md": { + "sha256": "64be51e300d0b9b5b14068559896424e3b6fe29322910fc3f37b48cd9629c68c", + "version": "2.3.7", + "status": "managed" + }, + ".github/agents/task-reviewer.agent.md": { + "sha256": "5babe37c8a5414183ca13379d85b275b5a785a726a5af64086593d70a06376e3", + "version": "2.3.7", + "status": "managed" + }, + ".github/agents/task-implementor.agent.md": { + "sha256": "53fe12c092087c402bb26657fa905251a59c09dcffb8c4c0d38ae46b2f16d776", + "version": "2.3.7", + "status": "managed" + } + }, + "installed": "2026-02-13T18:53:54.3160460-08:00" +} diff --git a/.vscode/mcp.json b/.vscode/mcp.json new file mode 100644 index 0000000..ff4bea6 --- /dev/null +++ b/.vscode/mcp.json @@ -0,0 +1,22 @@ +{ + "servers": { + "github": { + "type": "http", + "url": "https://api.githubcopilot.com/mcp/" + }, + "context7": { + "type": "stdio", + "command": "npx", + "args": ["-y", "@upstash/context7-mcp"] + }, + "microsoft-docs": { + "type": "http", + "url": "https://learn.microsoft.com/api/mcp" + }, + "tavily": { + "url": "https://mcp.tavily.com/mcp/?tavilyApiKey=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", + "type": "http" + } + }, + "inputs": [] +} diff --git a/docs/adrs/0001-csv-output-quoting-strategy.md b/docs/adrs/0001-csv-output-quoting-strategy.md new file mode 100644 index 0000000..dc9c09c --- /dev/null +++ b/docs/adrs/0001-csv-output-quoting-strategy.md @@ -0,0 +1,38 @@ +# ADR 0001: CSV Output Quoting Strategy + +**Status**: Accepted +**Date**: 2026-02-13 +**Phase**: 001-baseline-sdd-spec / Phase 2, Task T013 + +## Context + +FR-054 requires: "System MUST quote all fields in CSV output to ensure round-trip safety." +The plan's coding standards also state: "CSV writers use `QuoteStyle::Always` for quote safety." + +The implementation in `src/io_utils.rs` used `csv::QuoteStyle::Necessary`, which only +quotes fields when they contain delimiters, quotes, or newlines.

Schema inference algorithm and type resolution + +**Decision**: The existing inference engine samples up to N rows (default 2,000; +0 = full scan), performs per-column type voting across 10 candidate types, and +selects the narrowest type that accommodates all sampled values. Tie-breaking +favors specificity: Currency > Decimal > Float > Integer > DateTime > Date > +Time > GUID > Boolean > String (String is the universal fallback). + +**Rationale**: Voting-based inference scales linearly with sample size and avoids +single-row anomalies skewing the result. The type priority order ensures the most +informative type wins when multiple types parse successfully. + +**Alternatives considered**: +- Full-file scan by default: rejected for performance — hundreds-of-GB files + would take minutes for inference alone. +- Machine-learning-based inference: rejected for complexity and non-determinism. + +### 2. Index binary format and versioning strategy + +**Decision**: The index uses `bincode` v2 serialization with a format version +field (`v2`). The serialized payload contains: version string, source headers, +a vector of `IndexVariant` structs (each with columns, directions, column types, +and a `BTreeMap, Vec>` mapping composite +keys to byte offsets), and total row count. + +**Rationale**: `bincode` provides compact, fast serialization. The version field +enables forward-compatible detection — if a newer format is loaded by an older +binary, the version mismatch is reported and the user is advised to rebuild. + +**Alternatives considered**: +- Custom binary format with magic bytes: rejected for maintenance cost. +- SQLite-based index: rejected for dependency weight and deployment complexity. +- Protobuf: rejected for schema-management overhead on a single-binary CLI tool. + +### 3. Expression engine integration patterns + +**Decision**: The expression engine wraps the `evalexpr` crate, registering +custom temporal functions (`date_add`, `date_sub`, `date_diff_days`, +`date_format`, `datetime_add_seconds`, `datetime_diff_seconds`, +`datetime_format`, `datetime_to_date`, `datetime_to_time`, `time_add_seconds`, +`time_diff_seconds`) and string functions (`concat`). Row context is injected +per-row by populating an `evalexpr::HashMapContext` with column values mapped +to their names and positional aliases (`c0`, `c1`, …). + +**Rationale**: `evalexpr` provides a safe, sandboxed expression evaluator with +no filesystem or network access, suitable for user-provided formulas. Custom +function registration extends it for domain-specific temporal operations. + +**Alternatives considered**: +- Lua/Rhai embedded scripting: rejected for security surface and binary size. +- Custom parser: rejected for development cost and diminishing returns. + +### 4. Encoding transcoding approach + +**Decision**: Uses `encoding_rs` + `encoding_rs_io` for streaming transcoding. +Input encoding is specified via `--input-encoding` (defaults to UTF-8). Output +encoding via `--output-encoding` (defaults to UTF-8). The transcoding wraps the +raw reader/writer in a `DecodeReaderBytes` adapter, enabling transparent +conversion without buffering the entire file. + +**Rationale**: `encoding_rs` is the Mozilla-maintained encoding library used in +Firefox, providing correct, fast transcoding for all WHATWG-specified encodings. +Streaming adapter avoids memory overhead. + +**Alternatives considered**: +- `iconv` bindings: rejected for cross-platform issues on Windows. +- Pre-conversion to UTF-8 temp file: rejected for disk I/O overhead. + +### 5. Delimiter auto-detection strategy + +**Decision**: Delimiter is inferred from file extension: `.csv` → comma, +`.tsv`/`.tab` → tab. Manual override via `--delimiter` accepts named values +(`tab`, `comma`, `pipe`, `semicolon`) or any single ASCII character. No +content-based sniffing is performed. + +**Rationale**: Extension-based detection is deterministic and fast. Content +sniffing (counting delimiters per line) is fragile with quoted fields and adds +latency. The manual override covers edge cases. + +**Alternatives considered**: +- Statistical delimiter sniffing: rejected for fragility with multi-line quoted + fields and ambiguous cases (semicolons in addresses). + +### 6. Error handling architecture + +**Decision**: The crate uses a hybrid error strategy: `anyhow::Result` at +command boundaries for rich context chains, and `thiserror`-derived enums for +structured errors within modules. The `?` operator propagates errors upward. +The CLI layer formats errors for human consumption and sets exit codes +(0 = success, non-zero = failure). + +**Rationale**: `anyhow` excels at ad-hoc context attachment (`with_context`), +while `thiserror` enables pattern-matching on specific failure modes in tests +and internal logic. The combination is idiomatic Rust for CLI applications. + +**Alternatives considered**: +- Pure `thiserror` everywhere: rejected for excessive boilerplate in boundary + code that just needs to add context strings. +- Pure `anyhow` everywhere: rejected for loss of structured error matching in + internal modules. + +### 7. Streaming sort via index + +**Decision**: When a prebuilt index variant matches the requested sort, the +process command reads byte offsets from the index's `BTreeMap` in sorted order +and seeks to each offset in the source CSV file, emitting rows without buffering +the entire dataset. This makes sort cost proportional to I/O (seek + read per +row) rather than O(n log n) in-memory sort. + +**Rationale**: For multi-GB files, in-memory sort is impractical. Index- +accelerated sort trades disk seeks for memory, enabling sorts on arbitrarily +large files with O(1) memory overhead (excluding the index structure itself). + +**Alternatives considered**: +- External merge sort: rejected for implementation complexity and temp file + management. +- Memory-mapped file sort: rejected for portability issues and non-deterministic + paging behavior. + +### 8. Schema YAML format compatibility + +**Decision**: Schemas are persisted as YAML files using `serde_yaml`. The format +includes `schema_version` (optional), `has_headers` flag, and a `columns` array +where each entry has `name`, `datatype`, optional `name_mapping` (rename), +optional `replace` array (value replacements), and optional `datatype_mappings` +array.

They point csv-managed at the file to automatically detect column names, infer data types, detect whether a header row exists, identify placeholder values (NA, N/A, #N/A, null), and produce a reusable schema definition file. + +**Why this priority**: Schema discovery is the foundation for every other operation. Without a schema, typed processing, verification, indexing, and statistics all operate in degraded or untyped mode. This is the first thing a new user does. + +**Independent Test**: Can be fully tested by running `schema probe` and `schema infer` against any CSV file and verifying the output schema matches the actual column structure and types. + +**Acceptance Scenarios**: + +1. **Given** a CSV file with mixed column types, **When** the user runs `schema probe`, **Then** the tool displays an inference table showing each column's name, detected type, sample values, and null/placeholder counts — without writing any file. +2. **Given** a CSV file, **When** the user runs `schema infer -o output-schema.yml`, **Then** a YAML schema file is written containing column order, types, optional renames, and a replace template if requested. +3. **Given** a CSV file without a header row, **When** the user runs `schema infer`, **Then** the tool detects the absence of headers, assigns synthetic names (`field_0`, `field_1`, …), and produces a valid schema. +4. **Given** a CSV file with NA-style placeholders, **When** the user runs `schema probe --na-behavior fill --na-fill "MISSING"`, **Then** placeholder values are normalized to the specified fill value in the inference output. +5. **Given** an existing schema and a modified CSV, **When** the user runs `schema infer --diff existing-schema.yml`, **Then** a unified diff is displayed showing column additions, removals, and type changes. +6. **Given** a CSV file, **When** the user runs `schema infer --snapshot snapshot.json`, **Then** a snapshot is written containing a SHA-256 hash of the header layout and type assignments, enabling future regression detection. + +--- + +### User Story 2 — Data Transformation & Processing (Priority: P1) + +A data scientist needs to filter, sort, project, derive new columns, and transform a CSV file before feeding it to a training pipeline. They use the `process` command to apply a chain of operations in a single pass: schema-driven type mappings, value replacements, row filters, column selection/exclusion, derived expressions, sorting (optionally accelerated by a prebuilt index), and output in CSV or table format. + +**Why this priority**: Processing is the core value proposition — transforming raw data into pipeline-ready output. This is the command users invoke most frequently. + +**Independent Test**: Can be fully tested by running `process` with filters, derives, sort, and column selection against a known CSV and verifying the output matches expected rows and values. + +**Acceptance Scenarios**: + +1. **Given** a CSV file and a schema, **When** the user runs `process` with `--filter "amount >= 100"`, **Then** only rows where the typed value of `amount` is at least 100 appear in output. +2. **Given** a CSV file, **When** the user runs `process` with `--derive "total_with_tax=amount*1.0825"`, **Then** a new column `total_with_tax` appears in the output with correctly computed values. +3. **Given** a CSV file and an index file, **When** the user runs `process` with `--sort order_date:asc` and the index contains a matching variant, **Then** output is sorted using the index (not an in-memory sort) and performance is proportional to I/O rather than row count. +4. **Given** a CSV file, **When** the user runs `process` with `--columns name,email --exclude-columns internal_id`, **Then** only the specified columns appear, excluding the named exclusions. +5. **Given** a CSV file with boolean values in various formats (yes/no, 1/0, true/false), **When** the user runs `process` with `--boolean-format true-false`, **Then** all boolean columns are normalized to `true`/`false` in output. +6. **Given** a CSV file, **When** the user runs `process` with `--preview --limit 15`, **Then** the first 15 rows are rendered as a formatted table on stdout, and no output file is written. +7. **Given** a schema with value replacements (e.g., "M" → "Male"), **When** the user runs `process` with that schema, **Then** replacement mappings are applied to matching cell values in the output. +8. **Given** a schema with datatype mappings (e.g., rounding a decimal to 2 places), **When** the user runs `process` with `--apply-mappings`, **Then** mapping transformations are applied before final type parsing. + +--- + +### User Story 3 — Schema Verification (Priority: P1) + +A data engineer needs to validate that incoming CSV files conform to an expected schema before loading them into a data warehouse. They run the `schema verify` command against one or more input files and receive a report of any rows or cells that violate the schema's type or value constraints. + +**Why this priority**: Verification is the gatekeeping function — preventing bad data from entering downstream systems. In production pipelines, this is used as a pre-load validation step. + +**Independent Test**: Can be fully tested by running `schema verify` against a CSV file with known invalid rows and confirming the tool reports the correct violations. + +**Acceptance Scenarios**: + +1. **Given** a schema and a CSV file where some cells contain values that do not match the declared type, **When** the user runs `schema verify`, **Then** a summary report shows the count of invalid cells per column. +2. **Given** a schema and a CSV file with invalid rows, **When** the user runs `schema verify --report-invalid detail`, **Then** a detail report lists each invalid row number, column, raw value, and expected type. +3. **Given** a schema and a CSV file with an incompatible header (missing or extra columns), **When** the user runs `schema verify`, **Then** the tool reports the header mismatch and exits with a non-zero status. +4. **Given** a schema and multiple CSV files, **When** the user runs `schema verify -i file1.csv -i file2.csv`, **Then** each file is verified independently and results are reported per file. +5. **Given** a schema and a CSV with thousands of invalid rows, **When** the user uses `--report-invalid detail 50`, **Then** the detail report is capped at 50 entries with a note indicating more exist. + +--- + +### User Story 4 — B-Tree Indexing for Sort Acceleration (Priority: P2) + +A data engineer frequently sorts large CSV files on the same columns. They build a multi-variant index file once, then reference it in subsequent `process` runs to avoid expensive in-memory sorts. The index stores byte offsets keyed by column values and supports multiple named variants with different column/direction combinations. + +**Why this priority**: Indexing is a performance multiplier for repeated sort operations on large files. It's not required for basic use but becomes essential for production-scale workflows. + +**Independent Test**: Can be fully tested by building an index, then running `process` with a matching sort and verifying the output order matches the index definition. + +**Acceptance Scenarios**: + +1. **Given** a CSV file, **When** the user runs `index` with `--spec default=order_date:asc,customer_id:asc`, **Then** a binary index file is written containing a named variant "default" with ascending sort on both columns. +2. **Given** an index build command with multiple `--spec` flags, **When** the index is built, **Then** the resulting `.idx` file contains all named variants and each can be used independently. +3. **Given** a `--covering` spec like `geo=date:asc|desc,customer:asc`, **When** the index is built, **Then** the tool generates all direction/prefix permutations as separate variants under the "geo" family. +4. **Given** a `process` command with `--sort` that partially matches an index variant, **When** the tool selects an index variant, **Then** it chooses the variant with the longest matching column prefix. +5. **Given** a `process` command with `--index-variant specific_name`, **When** that variant does not exist in the index file, **Then** the tool reports a clear error identifying the missing variant. + +--- + +### User Story 5 — Summary Statistics & Frequency Analysis (Priority: P2) + +A data scientist wants to quickly profile a CSV file's numeric and temporal columns — computing count, min, max, mean, median, and standard deviation — or generate frequency counts (top-N distinct values) for categorical columns. + +**Why this priority**: Statistics and frequency counts are essential for data profiling and quality assessment. They enable quick understanding of data distributions before building more complex transformations. + +**Independent Test**: Can be fully tested by running `stats` and `stats --frequency` against a known CSV and verifying computed metrics match expected values. + +**Acceptance Scenarios**: + +1. **Given** a CSV file with numeric columns, **When** the user runs `stats`, **Then** the tool outputs count, min, max, mean, median, and standard deviation for each numeric column. +2. **Given** a CSV file with temporal columns (date, datetime, time), **When** the user runs `stats`, **Then** the tool outputs meaningful temporal metrics (earliest, latest, count). +3. **Given** a CSV file, **When** the user runs `stats --frequency --top 10`, **Then** the top 10 distinct values per column are displayed with counts and percentages. +4. **Given** a CSV file with schema, **When** the user runs `stats --filter "region = US"`, **Then** statistics are computed only for rows matching the filter. +5. **Given** a CSV file with decimal/currency columns, **When** the user runs `stats`, **Then** precision and scale are preserved in the statistical output. + +--- + +### User Story 6 — Multi-File Append (Priority: P2) + +A data engineer needs to concatenate multiple CSV files that share the same schema into a single output file. The tool validates header consistency across all inputs and optionally enforces schema compliance during the union. + +**Why this priority**: Multi-file append is a common ETL pattern when data arrives in batches (daily files, partitioned exports). Header consistency validation prevents silent data corruption. + +**Independent Test**: Can be fully tested by appending two or more CSV files and verifying the output contains all rows with correct headers. + +**Acceptance Scenarios**: + +1. **Given** multiple CSV files with identical headers, **When** the user runs `append -i a.csv -i b.csv -o combined.csv`, **Then** a single output file contains all rows from both inputs with the header written once. +2. **Given** multiple CSV files with mismatched headers, **When** the user runs `append`, **Then** the tool reports a header mismatch error and does not produce output. +3. **Given** multiple CSV files and a schema, **When** the user runs `append` with `--schema`, **Then** each row is validated against the schema during the union and type violations are reported. + +--- + +### User Story 7 — Streaming Pipeline Support (Priority: P2) + +A data engineer chains multiple csv-managed commands together using shell pipes, reading from stdin and writing to stdout, to build multi-stage data transformation pipelines without intermediate files. + +**Why this priority**: Pipeline composition is a key Unix-philosophy capability that enables complex workflows without disk I/O overhead for intermediate results. + +**Independent Test**: Can be fully tested by piping the output of one command into another (e.g., `process | stats`) and verifying the final output is correct. + +**Acceptance Scenarios**: + +1. **Given** a CSV file, **When** the user pipes `process` output into `stats` using `-i -` for stdin, **Then** statistics are computed on the transformed output without writing an intermediate file. +2. **Given** a CSV file with non-UTF-8 encoding, **When** the user runs `process` with `--input-encoding windows-1252 --output-encoding utf-8`, **Then** the output is correctly transcoded. +3. **Given** a process command with `--preview`, **When** the user pipes it downstream, **Then** the preview mode writes formatted table output to stdout (not CSV), making it unsuitable for piping and the tool behaves accordingly. + +--- + +### User Story 8 — Expression Engine for Derived Logic & Filtering (Priority: P3) + +A data scientist needs to compute complex derived columns or apply sophisticated filter conditions that go beyond simple comparisons. They use the expression engine to write formulas involving arithmetic, string operations, conditional logic, and temporal helper functions. + +**Why this priority**: The expression engine powers advanced use cases (date arithmetic, conditional flags, multi-column calculations) that differentiate csv-managed from simpler CSV tools. + +**Independent Test**: Can be fully tested by running `process` with `--derive` and `--filter-expr` arguments and verifying computed values and filtered results. + +**Acceptance Scenarios**: + +1. **Given** a CSV with date columns, **When** the user derives `ship_lag=date_diff_days(shipped_at,ordered_at)`, **Then** the output column contains the integer day difference for each row. +2. **Given** a CSV with numeric columns, **When** the user applies `--filter-expr "amount > 1000 && status == \"shipped\""`, **Then** only rows matching both conditions appear. +3. **Given** a CSV, **When** the user derives `channel_tag=concat(channel,"-",region)`, **Then** the output column contains the concatenated string. +4. **Given** `--row-numbers` is enabled, **When** the user derives `row_idx=row_number`, **Then** each row's sequential index is available in the expression context. +5. **Given** a CSV, **When** the user uses positional aliases `c0`, `c1` in expressions, **Then** columns are resolved by their zero-based position. + +--- + +### User Story 9 — Schema Column Listing (Priority: P3) + +A user wants to quickly view the columns and types defined in an existing schema file without opening it in a text editor. They run `schema columns` to see a formatted table of column positions, names, types, and any renames. + +**Why this priority**: A convenience feature that improves workflow efficiency when working with schemas across multiple terminal sessions. + +**Independent Test**: Can be fully tested by running `schema columns -m schema.yml` and verifying the table output matches the schema definition. + +**Acceptance Scenarios**: + +1. **Given** a schema YAML file, **When** the user runs `schema columns -m schema.yml`, **Then** a formatted table shows position, column name, data type, and renamed output name for each column. +2. **Given** a schema YAML file containing columns with renames and datatype mappings, **When** the user runs `schema columns -m schema.yml`, **Then** the table displays both original and renamed column names alongside their declared data types. + +--- + +### User Story 10 — Self-Install (Priority: P3) + +A user wants to install or update csv-managed using a convenient wrapper command rather than remembering the full `cargo install` incantation. + +**Why this priority**: A quality-of-life feature that simplifies installation for users who already have the tool. + +**Independent Test**: Can be fully tested by running `install --version X.Y.Z` and verifying the correct cargo command is executed. + +**Acceptance Scenarios**: + +1. **Given** csv-managed is already built, **When** the user runs `install --locked`, **Then** the tool executes `cargo install csv-managed --locked` using the current source. +2. **Given** a specific version is needed, **When** the user runs `install --version 1.0.2`, **Then** that exact version is installed from crates.io. + +--- + +### Edge Cases + +- What happens when a CSV file is empty (zero rows)? The tool should report the empty state gracefully without crashing. +- What happens when a CSV file has only a header row and no data rows? Statistics should report zero counts; verification should succeed. +- What happens when a filter expression references a column that does not exist? The tool should report a clear error identifying the unknown column. +- What happens when a derive expression has a syntax error? The tool should report the parse error with the expression text and position. +- What happens when an index file was built with a different index format version? The tool should detect format version incompatibility and suggest rebuilding the index. +- What happens when stdin provides no data (empty pipe)? The tool should detect the empty stream and report it. +- What happens when a decimal value exceeds the maximum precision (28 digits)? The tool should report a precision overflow error. +- What happens when a schema defines a column rename but the CSV header uses the original name? The tool should map the original header name to the renamed output name transparently. +- What happens when multiple `--filter` flags are specified? They should be combined with AND semantics. +- What happens when `--sort` is specified but no index matches and the file is very large? The tool should fall back to in-memory sort and complete correctly; users should be aware this buffers all rows in memory and should prefer building an index for large files. + +## Requirements

violation, missing file, invalid expression), enabling reliable use in automated pipelines and shell scripts. + +### Key Entities + +- **Schema**: Defines the expected structure of a CSV file — column order, names, data types, optional renames, datatype mapping chains, and value replacement rules. Persisted as YAML. +- **Column Type**: One of 10 supported types (String, Integer, Float, Boolean, Date, DateTime, Time, GUID, Decimal, Currency) that determines parsing, comparison, and output formatting rules. +- **Value**: A typed cell value parsed from a raw CSV field according to its column type. Supports null-safe ordering and expression evaluation. +- **Index**: A binary file containing one or more named variants. Each variant maps sorted composite key values to byte offsets in the source CSV for O(1) seek access. +- **Index Variant**: A named sort configuration within an index file, defined by column names and per-column sort directions (ascending/descending). +- **Datatype Mapping**: An ordered transformation chain applied to raw cell values before final type parsing — including parse, round, trim, and case operations. +- **Value Replacement**: A mapping from a raw cell value to a normalized output value, applied per-column after datatype mappings but before final type parsing. +- **Snapshot**: A regression-detection artifact containing a SHA-256 hash of header layout and type assignments, enabling future regression detection. +- **Filter Condition**: A typed comparison rule (column, operator, value) used to include or exclude rows during processing. +- **Derived Column**: A new output column computed from an expression involving existing columns, constants, and built-in functions. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: Users can discover the schema of an unknown CSV file in under 30 seconds for files up to 10 GB, receiving a complete type-annotated column listing. +- **SC-002**: Users can filter, sort (with index), project, and derive columns from arbitrarily large CSV files in a single streaming pass, bounded only by disk I/O rather than available memory. +- **SC-003**: Users can validate a CSV file against a schema and receive a clear, actionable report of all type violations categorized by column. +- **SC-004**: Users can build an index once and reuse it across multiple process runs, reducing sort time proportionally to avoiding full-file scans. +- **SC-005**: Users can chain multiple csv-managed commands in a shell pipeline, reading from stdin and writing to stdout, without requiring intermediate files. +- **SC-006**: Users can profile a CSV file's numeric distributions (count, min, max, mean, median, std dev) or categorical distributions (frequency counts) in a single command. +- **SC-007**: Users can concatenate multiple same-schema CSV files with header consistency validation, preventing silent column misalignment. +- **SC-008**: All existing automated tests pass, all code meets formatting standards, and no compiler or linter warnings are produced. +- **SC-009**: The tool handles CSV files with non-UTF-8 encodings correctly when the appropriate `--input-encoding` flag is provided. +- **SC-010**: All error messages include contextual information about the operation that failed, the file being processed, and the specific row/column when applicable. + +## Clarifications + +### Session 2026-02-14 + +- Q: Should this baseline spec cover only implemented features (v1.0.2) or the full roadmap? → A: Current implementation only; future features will receive their own specs via `/speckit.specify`. +- Q: Should the implemented-but-CLI-disabled join subcommand be documented in this spec? → A: Exclude; note as dormant pending v2.5.0 redesign. +- Q: Should operation timing output and configurable log levels be formal requirements? → A: Yes, add requirements for both operation timing and configurable log levels. +- Q: What is the realistic file size upper bound for the tool? → A: Indexed sort should be streaming (no in-memory buffering), enabling arbitrarily large files. Only non-indexed sort and median require buffering and are memory-bound. +- Q: Should the spec define explicit exit code behavior? → A: Yes, add requirement for 0 on success and non-zero on any error. +- Q: Should the `--skip-mappings` and `--output-delimiter` flags have their own functional requirements? → A: No. These flags invert or extend existing requirements (FR-022 for mappings, FR-051 for delimiters) and are documented in the CLI contract. They do not introduce new behavior categories. + +## Assumptions + +- This specification documents the feature set as of v1.0.2. Planned features from the roadmap (v1.1.0 through v6.0.0) are out of scope and will each receive their own specification when entering development. +- The tool is designed as a single-user CLI utility, not a multi-tenant service. Concurrency is not a design requirement. +- Input files are expected to be well-formed CSV/TSV with consistent row lengths. The tool reports but does not attempt to repair structurally malformed files. +- The `join` subcommand has a complete implementation in code but is intentionally disabled in the CLI. It is excluded from this baseline specification and will be re-introduced with streaming enhancements in a future v2.5.0 spec. +- Schema files follow the `*-schema.yml` naming convention by default, though the user may specify any path. +- Index files follow the `.idx` extension convention. +- The tool prioritizes streaming/sequential processing to minimize memory footprint. Filtering, projection, derivation, verification, indexed sort, and append all operate in streaming mode. Only non-indexed sort and median computation buffer data in memory and are therefore bounded by available system memory. diff --git a/specs/001-baseline-sdd-spec/tasks.md b/specs/001-baseline-sdd-spec/tasks.md new file mode 100644 index 0000000..48669f0 --- /dev/null +++ b/specs/001-baseline-sdd-spec/tasks.md @@ -0,0 +1,499 @@ +# Tasks: CSV-Managed — Baseline SDD Specification + +**Input**: Design documents from `/specs/001-baseline-sdd-spec/` +**Prerequisites**: plan.md (required), spec.md (required), research.md, data-model.md, contracts/cli-contract.md, quickstart.md + +**Tests**: Included — the baseline spec requires validating existing test coverage against all 59 functional requirements and 10 user stories. + +**Organization**: Tasks are grouped by user story to enable independent validation and gap-filling for each story.
