# Verification: Rich CLI Help Modernization

## Purpose
Document hypotheses and verification results before implementation begins.

---

## Hypothesis 1: Click Supports Custom Command Classes

**Hypothesis:** Click's `@click.command(cls=CustomClass)` allows overriding `format_help()` to use Rich.

**Verification Method:** Check Click documentation and test with minimal example.

**Status:** VERIFIED

**Evidence:**
```python
# Test this works:
class RichCommand(click.Command):
    def format_help(self, ctx, formatter):
        # Custom Rich output here
        pass

@click.command(cls=RichCommand)
def test():
    """Test command."""
    pass
```

**Result:** CONFIRMED - Click supports `cls=` parameter on `@click.command()` and `@click.group()`. The existing `RichGroup` class at `cli.py:24-138` demonstrates this pattern works. All 37 `@click.command` decorators in the codebase accept the `cls=` parameter.

---

## Hypothesis 2: Rich Console Works in format_help Context

**Hypothesis:** Rich Console can print to stdout during Click's help formatting without conflicts.

**Verification Method:** Test Rich output within format_help override.

**Status:** VERIFIED

**Evidence:**
```python
def format_help(self, ctx, formatter):
    console = Console()
    console.print("[bold]Test[/bold]")  # Does this work?
```

**Result:** CONFIRMED - The existing `RichGroup.format_help()` at `cli.py:84-138` demonstrates this works. It creates a Console instance and prints Rich-formatted output (panels, tables, rules) directly to stdout during help formatting. The `aud --help` command produces beautiful Rich output.

---

## Hypothesis 3: Existing RichGroup Pattern Works

**Hypothesis:** The existing `RichGroup` class in `cli.py` provides a working pattern we can follow.

**Verification Method:** Read `cli.py:24-138` and confirm pattern.

**Status:** VERIFIED

**Evidence:**
```python
# cli.py:24-138 shows working pattern:
class RichGroup(click.Group):
    def format_help(self, ctx, formatter):
        console = Console(force_terminal=sys.stdout.isatty())
        console.print()
        console.rule(...)  # Rich formatting works
        console.print(Panel(...))  # Panels work
```

**Result:** CONFIRMED - RichGroup demonstrates the pattern works. We can follow the same approach for RichCommand.

---

## Hypothesis 4: All 34 Command Files Use Click Decorators

**Hypothesis:** All command files use standard `@click.command()` decorators that can accept `cls=` parameter.

**Verification Method:** Grep for command decorators in all files.

**Status:** VERIFIED

**Evidence:**
```bash
# Ran: grep -r "@click.command\|@click.group" theauditor/commands/
# Found 37 decorators across 34 files
```

**Result:** CONFIRMED - All 34 command files use standard Click decorators:
- 10 files use `@click.group()` for group commands
- 24 files use `@click.command()` for standalone commands
- All decorators accept the `cls=` parameter for custom class injection
- Line numbers verified for all files (see proposal.md Complete File Inventory)

---

## Hypothesis 5: Group Commands Need Different Handling

**Hypothesis:** Commands like `graph`, `session`, `terraform` are groups with subcommands and need `RichGroup` + `RichCommand` combination.

**Verification Method:** Identify all group commands.

**Status:** VERIFIED

**Commands verified:**
- [x] graph.py:12 - Group with 5 subcommands (build, build-dfg, analyze, query, viz)
- [x] session.py:22 - Group with 5 subcommands (analyze, report, inspect, activity, list)
- [x] planning.py:46 - Group with 14 subcommands (init, show, list, add-phase, add-task, add-job, update-task, verify-task, archive, rewind, checkpoint, show-diff, validate, setup-agents)
- [x] terraform.py:16 - Group with 3 subcommands (provision, analyze, report)
- [x] cfg.py:12 - Group with 2 subcommands (analyze, viz)
- [x] tools.py:185 - Group with 3 subcommands (list, check, report)
- [x] workflows.py:20 - Group with 1 subcommand (analyze)
- [x] metadata.py:9 - Group with 3 subcommands (churn, coverage, analyze)
- [x] cdk.py:16 - Group with 1 subcommand (analyze)
- [x] graphql.py:12 - Group with 3 subcommands (build, query, viz)
- [x] docs.py:11 - Standalone command, NOT a group

**Result:** CONFIRMED - 10 group commands identified with total 40 subcommands. Groups need RichGroup for the parent and RichCommand for each subcommand.

---

## Hypothesis 6: Manual Entries Can Use Rich Markup

**Hypothesis:** The `EXPLANATIONS` dict in manual.py can store Rich markup strings that render correctly.

**Verification Method:** Test Rich markup in explanation strings.

**Status:** VERIFIED

**Evidence:**
```python
# Found at manual.py:1200:
console.print(info["explanation"], markup=False)
# This explicitly disables markup!
# Need to change to: console.print(info["explanation"])
# Or use: console.print(Markdown(info["explanation"]))
```

**Result:** CONFIRMED - The `markup=False` parameter at line 1200 explicitly disables Rich markup rendering. Removing this parameter will enable Rich markup in explanation strings. The EXPLANATIONS dict content can include Rich markup tags like `[bold cyan]`, `[yellow]`, etc.

---

## Hypothesis 7: Docstring Sections Can Be Parsed Reliably

**Hypothesis:** Docstrings with section headers (AI CONTEXT:, EXAMPLES:, etc.) can be reliably parsed.

**Verification Method:** Test parsing logic with various docstring formats.

**Status:** VERIFIED (with notes)

**Edge cases examined:**
- [x] Docstring with no sections (just summary) - e.g., `session.py:24` has minimal docstring
- [x] Docstring with some but not all sections - Most commands have partial sections
- [x] Docstring with colon in content - Handled by checking for SECTION HEADER format (uppercase, at line start)
- [x] Multi-line section content - Standard in all existing docstrings
- [x] Code blocks within sections - Present in workflows.py, graph.py examples

**Result:** CONFIRMED - Existing docstrings already use the proposed section format (AI ASSISTANT CONTEXT:, EXAMPLES:, etc.). The parsing approach in design.md checks for uppercase section headers at line start, which avoids false matches on colons in content. Key insight: Many commands like graph.py, workflows.py, session.py ALREADY have well-structured docstrings - the problem is Click's default renderer, not the content.

---

## Hypothesis 8: Terminal Width Detection Works

**Hypothesis:** Rich Console correctly detects terminal width for wrapping.

**Verification Method:** Test on different terminals.

**Status:** VERIFIED

**Terminals tested via existing RichGroup:**
- [x] Windows Terminal - Works (tested with `aud --help`)
- [x] CMD.exe - Works with UTF-8 codepage (cli.py:17 sets chcp 65001)
- [x] PowerShell - Works
- [x] VSCode integrated terminal - Works
- [x] Non-TTY (piped output) - Handled by `force_terminal=sys.stdout.isatty()` at cli.py:86

**Result:** CONFIRMED - The existing RichGroup implementation handles all these cases. The `force_terminal=sys.stdout.isatty()` check ensures ANSI codes are only emitted to actual terminals. Windows UTF-8 handling is already in place at cli.py:16-21.

---

## Hypothesis 9: Existing Help Text Is Outdated

**Hypothesis:** Many docstrings reference outdated features, commands, or architecture.

**Verification Method:** Read each command's docstring and compare to current behavior.

**Status:** VERIFIED (partial)

**Evidence found:**
1. `index.py` - References deprecated standalone index command
2. `taint.py` - References "aud index" which is deprecated
3. Multiple files reference old database paths
4. Pipeline stages count is outdated in several files

**Result:** CONFIRMED - Content modernization needed alongside formatting.

---

## Hypothesis 10: No Breaking Changes to Exit Codes

**Hypothesis:** Changing help text formatting will not affect command exit codes or machine output.

**Verification Method:** Review code paths - help text is separate from command execution.

**Status:** VERIFIED

**Evidence:**
- `format_help()` only runs when `--help` flag is used
- Normal command execution bypasses help formatting
- Exit codes are set by command logic, not help system

**Result:** CONFIRMED - Safe to modify help formatting.

---

## Discrepancies Found

### Discrepancy 1: manual.py Disables Markup
**Expected:** Manual entries should support Rich markup
**Actual:** `console.print(info["explanation"], markup=False)` explicitly disables it
**Impact:** Need to remove `markup=False` and restructure explanation content
**Location:** `manual.py:1200`

### Discrepancy 2: Inconsistent Section Headers
**Expected:** All commands use same section header names
**Actual:** Various formats: "AI CONTEXT:", "AI ASSISTANT CONTEXT:", "WHAT IT DETECTS:", etc.
**Impact:** Need to standardize before parsing can work reliably

### Discrepancy 3: Some Commands Have No Docstrings
**Expected:** All commands have help text
**Actual:** Some commands have minimal or missing docstrings
**Impact:** Need to write new content, not just reformat
