…453) (#458)

* fix(ci): add visibility message when PR maintenance processes 0 PRs

Closes #400

When the PR maintenance workflow runs and finds no PRs requiring
automated action, users couldn't tell why "0 PRs processed" appeared.

This adds a GITHUB_STEP_SUMMARY message explaining:
- Total PRs scanned
- Actions taken (comments acknowledged, conflicts resolved)
- Why no actions were needed (normal when awaiting human review)

Changes:
- Add TotalPRs to results for visibility reporting
- Add step summary output in GitHub Actions context
- Explain "no actions" scenario (awaiting review, no bot comments)

This is the minimal fix that was attempted in PR #395, which scope-
exploded to 847 lines. This fix is 42 lines as intended.

* fix: Distinguish bot vs human PRs for CHANGES_REQUESTED handling

BREAKING CHANGE: Bot-authored PRs with CHANGES_REQUESTED are no longer
skipped as "blocked". They are now tracked separately in ActionRequired
for agent intervention via pr-comment-responder.

The previous logic incorrectly treated ALL CHANGES_REQUESTED PRs as
"blocked, needs human action". This was wrong for bot-authored PRs:

- Human-authored PR with CHANGES_REQUESTED: Truly blocked, human must act
- Bot-authored PR with CHANGES_REQUESTED: Agent should address feedback

Changes:
- Add Test-IsBotAuthor helper function with documented bot patterns
- Update Invoke-PRMaintenance to distinguish bot vs human authors
- Add ActionRequired list to results for bot PRs needing attention
- Update GITHUB_STEP_SUMMARY to list actionable bot PRs
- Add 7 tests for Test-IsBotAuthor function
- Create memory: pr-changes-requested-semantics

Evidence: PRs #247, #246, #235 were incorrectly skipped when they had
CHANGES_REQUESTED from human reviewers on bot-authored code.

* feat: Add nuanced bot categorization for CHANGES_REQUESTED handling

Different bot types require different actions when CHANGES_REQUESTED:

- agent-controlled (rjmurillo-bot): Use /pr-review via pr-comment-responder
- mention-triggered (copilot-swe-agent): Add @copilot comment
- command-triggered (dependabot[bot]): Use @dependabot commands
- unknown-bot: Requires manual review

Changes:
- Add Get-BotAuthorInfo function with category, action, and mention fields
- Refactor Test-IsBotAuthor to use Get-BotAuthorInfo
- Update console output to group by category with specific actions
- Update GITHUB_STEP_SUMMARY with category-specific recommended actions
- Add 9 tests for Get-BotAuthorInfo covering all categories
- Update memory with nuanced handling documentation

Evidence: copilot-swe-agent PRs need @copilot mention to act, unlike
agent-controlled bots that can be addressed directly.

* fix: Run maintenance tasks regardless of CHANGES_REQUESTED status

CHANGES_REQUESTED status only indicates who can address reviewer feedback.
Maintenance tasks should ALWAYS run:

- Resolve merge conflicts (keeps PR mergeable)
- Acknowledge bot comments (shows engagement)
- Check for similar PRs (informational)

Previously, human-authored PRs with CHANGES_REQUESTED were skipped entirely.
Now they are processed for maintenance but listed as Blocked for feedback.

## Protocol Changes
- rjmurillo-bot activates when: PR author, added as reviewer, or @mentioned
- CHANGES_REQUESTED only triggers /pr-review when bot is author or reviewer
- @mention → process ONLY that comment, add eyes only to that comment
- Maintenance = merge conflict resolution only

* fix(pr-maintenance): resolve double-nested array issue in Get-SimilarPRs

The combination of Write-Output -NoEnumerate in the function and @()
wrapper at the call site created a double-nested array structure.
When iterating, foreach received the entire inner array as a single
item instead of individual PSCustomObject elements.

Changes:
- Remove Write-Output -NoEnumerate from Get-SimilarPRs function
- Use simple return statements instead
- Change hashtable to PSCustomObject with lowercase property names
- Add DryRun parameter at script level (was missing from param block)
- Pass DryRun through to Invoke-PRMaintenance function call

Root cause: Mocks used PascalCase properties that matched the code,
but the real GitHub API returns lowercase. Static analysis passed
but actual execution revealed the runtime issue.

Lesson: Integration testing against real APIs is essential to catch
casing and structure issues that mocks cannot reveal.

which fixed double-nested array bug in Get-SimilarPRs function.

Analysis Findings:
- Root cause: Write-Output -NoEnumerate + @() wrapper = double-nesting
- Unit tests passed (100% coverage) but runtime failed on all 15 PRs
- Mock fidelity gap: Tests used PascalCase, API returned lowercase
- Testing gap: No integration tests for GitHub API calls

Extracted Learnings (4 skills, all ≥90% atomicity):
- Skill-PowerShell-004: Array return pattern (95%)
- Skill-Testing-003: Integration test requirement (92%)
- Skill-Testing-006: Mock structure fidelity (93%)
- Skill-Testing-004: Type assertions (90%)

Process Improvements:
- Add integration tests for external API calls
- Validate mocks match actual API response structure
- Assert returned object types not just values
- Document PowerShell array handling best practices

- .agents/retrospective/402-double-nested-array-debug.md (comprehensive analysis)
- .serena/memories/powershell-array-handling.md (array patterns)
- .serena/memories/testing-mock-fidelity.md (testing requirements)

* feat(pr-maintenance): implement Get-UnaddressedComments function

Add function to detect bot comments in any unresolved state:
- NEW (unacknowledged, eyes=0)
- ACKNOWLEDGED (eyes>0 but thread unresolved)
- REPLIED (reply exists but thread unresolved)

Function queries Get-UnresolvedReviewThreads to identify threads where
isResolved=false, then filters bot comments matching either:
- reactions.eyes = 0 (unacknowledged), OR
- comment ID in unresolved thread list (acknowledged but unresolved)

This addresses the gap where PR #365 showed "all comments acknowledged"
but threads remained open. Get-UnacknowledgedComments detects NEW state
only; Get-UnaddressedComments detects all incomplete states.

Implements TASK-004 from acknowledged-vs-resolved feature plan.

TASK-006: Update PR classification to use Get-UnaddressedComments
- Replace Get-UnacknowledgedComments call with Get-UnaddressedComments

- Preserve Get-UnacknowledgedComments function for backward compatibility

TASK-007: Add granular ActionRequired reason classification
- UNRESOLVED_THREADS: Acknowledged but thread not resolved
- UNACKNOWLEDGED: Comments lacking eyes reaction
- UNRESOLVED_THREADS+UNACKNOWLEDGED: Both conditions present

This enables PR maintenance output to distinguish between comments that
need acknowledgment vs threads that need resolution, improving triage.

* fix(pr-maintenance): classify Copilot PRs as mention-triggered for @copilot synthesis

## Problem
PR #247 authored by copilot-swe-agent with CHANGES_REQUESTED was being
classified as "Human-authored" and blocked, when it should be actionable
by rjmurillo-bot to synthesize feedback and @copilot to unblock.

## Solution
- Add 'app/copilot-swe-agent' to mention-triggered bots list
- Create new classification branch for mention-triggered bots that:
  - Does NOT require rjmurillo-bot as reviewer
  - Adds to ActionRequired when CHANGES_REQUESTED or HAS_CONFLICTS
  - Sets requiresSynthesis=true for @copilot mention workflow

## Tests
- 5 new Pester tests covering positive, negative, and boundary cases
- 47.7% code coverage (39 tests passing)

## Documentation
- Added "Bot Categories and PR Handling" section to docs/autonomous-pr-monitor.md
- Documents mention-triggered category and Copilot PR handling workflow
