Add 5 BLOCKING constraints for parallel worktree execution:
1. Worktree Isolation - ALL changes contained within assigned worktree
2. Working Directory - MUST cd into worktree before file operations
3. Path Validation - paths relative to worktree root only
4. Git Operations - execute from within worktree directory
5. Verification Gate - check main repo for unexpected changes before cleanup

Violation of these constraints causes work leakage between PRs and merge conflicts.
- Clarify pr-comment-responder skill is optional (comment 2638201580, 2638201614)
- Improve warning message with actionable guidance (comment 2638201588)
- Add $LASTEXITCODE checks after git operations (comment 2638201593)
- Use default push behavior instead of hardcoded 'origin' (comment 2638201619)
- Add language specifier to usage code block (markdownlint MD040)

Comment 2638201604 dismissed as false positive - commit message already

DevOps Review: PR #10 - Static PR and Issue Labeling Workflows

Pipeline Impact Assessment

Area Impact Notes
Build None No changes to build processes
Test None No test modifications
Deploy None No deployment changes
Cost Low Two lightweight workflows, ~2min timeout each

CI/CD Quality Checks

Check Status Location
YAML syntax valid All 3 files
Actions pinned label-pr.yml:33, label-issues.yml:36
Secrets secure ⚠️ label-issues.yml:38
Permissions minimal Both workflows use minimal scopes
Shell scripts robust No shell scripts, JavaScript only

Findings

Severity Category Finding Location Fix
Medium Security actions/labeler@v5 not pinned to SHA label-pr.yml:33 Pin to actions/labeler@8558fd74291d67161a8a78ce36a881fa63b766a9 (v5.0.0)
Medium Security actions/github-script@v7 not pinned to SHA label-issues.yml:36 Pin to actions/github-script@60a0d83039c74a4aee543508d2ffcb1c3799cdea (v7.0.1)
Low Security Uses BOT_PAT instead of GITHUB_TOKEN label-issues.yml:38 Document why PAT is required or switch to GITHUB_TOKEN if sufficient
Low Best Practice Missing fail-fast consideration N/A Single-job workflows, not applicable

Positive Observations

  1. Proper concurrency control: Both workflows use cancel-in-progress: true to prevent duplicate runs
  2. Minimal permissions: contents: read + write access only where needed
  3. Bot actor filtering: Correctly skips dependabot[bot] and github-actions[bot]
  4. Reasonable timeouts: 2-minute timeout prevents runaway jobs
  5. Substantive edit filtering: Issue labeler correctly checks github.event.changes for title/body edits

Template Assessment

  • PR Template: Not modified in this PR
  • Issue Templates: Not modified in this PR
  • Template Issues: N/A

Automation Opportunities

Opportunity Type Benefit Effort
Extract issue keyword patterns to config file Configuration Easier maintenance of label rules Low
Add label sync for removed content Enhancement Labels removed when keywords no longer match Medium

Recommendations

  1. Pin actions to SHA for supply chain security compliance
  2. Document BOT_PAT requirement in workflow comments or README if GITHUB_TOKEN lacks permissions for cross-repo or elevated operations
  3. Consider enabling sync-labels: true in labeler.yml if labels should be removed when file patterns no longer match

Verdict

VERDICT: WARN
MESSAGE: Unpinned actions (v5, v7) should be pinned to SHA for security. BOT_PAT usage should be documented. No blocking issues.
Roadmap Review Details

Strategic Alignment Assessment

Criterion Rating Notes
Aligns with project goals High Supports infrastructure automation without AI dependency, improving reliability
Priority appropriate Medium Useful but not on roadmap; incremental improvement to repo maintainability
User value clear Medium Reduces triage burden for maintainers; no direct user-facing value
Investment justified High Standard GitHub Actions pattern; low maintenance burden

Feature Completeness

  • Scope Assessment: Right-sized
  • Ship Ready: Yes
  • MVP Complete: Yes
  • Enhancement Opportunities: Could add agent-skillbook, agent-task-generator, agent-high-level-advisor labels for remaining agents not covered (5 agents missing from labeler.yml)

Impact Analysis

Dimension Assessment Notes
User Value Low Benefits maintainers, not end-users of the agent system
Business Impact Low No monetization or growth impact; reduces operational friction
Technical Leverage Medium Reusable pattern; consistent labeling enables future automation (metrics, routing)
Competitive Position Neutral Standard practice for GitHub repos

Concerns

Priority Concern Recommendation
Low Missing 5 agent labels (skillbook, task-generator, high-level-advisor, independent-thinker, pr-comment-responder) Consider adding for completeness
Low Issue labeler uses BOT_PAT secret Verify secret exists; fallback to GITHUB_TOKEN if not needed
Low No explicit roadmap epic for this work Document as infrastructure improvement in changelog

Recommendations

  1. Merge as-is. This is a low-risk, deterministic improvement over AI-based triage.
  2. Consider adding the 5 missing agent labels in a follow-up PR for completeness.
  3. Update roadmap changelog to note this infrastructure improvement.

Verdict

VERDICT: PASS
MESSAGE: Change aligns with infrastructure automation goals. Static labeling is more reliable than AI triage. Low risk, low maintenance burden, incremental maintainer value.
Analyst Review Details

Let me check the repository for the files mentioned in the PR description.

Let me check for existing workflow patterns and any related AI triage workflows being replaced.

I have enough context to provide the analysis. The PR adds static labeling workflows as a complement/alternative to the existing AI-based triage.


Analysis: Static PR and Issue Labeling Workflows

Value Statement

This analysis evaluates new GitHub Actions workflows for deterministic, pattern-based labeling as an alternative to AI-based triage.

Code Quality Score

Criterion Score (1-5) Notes
Readability 5 Clear structure, well-organized sections with headers
Maintainability 4 Pattern-based config is easy to extend; 26 label rules add maintenance overhead
Consistency 5 Follows existing workflow patterns in repository
Simplicity 4 Simple approach; issue labeler JavaScript could be extracted

Overall: 4.5/5

Impact Assessment

  • Scope: Module-wide (GitHub Actions only)
  • Risk Level: Low
  • Affected Components: .github/workflows/, .github/labeler.yml, issue/PR labeling

Findings

Priority Category Finding Location
Medium Security Issue labeler uses BOT_PAT secret but PR labeler uses GITHUB_TOKEN. Inconsistent token usage may indicate unintended permissions. label-issues.yml:38
Low Maintainability Inline JavaScript in label-issues.yml (80+ lines) should be extracted to a separate file for testability. label-issues.yml:39-122
Low Overlap Both ai-issue-triage.yml and label-issues.yml trigger on same events (opened, reopened, edited). Potential duplicate label application. Both workflows
Low Pattern Agent patterns in labeler.yml require exact file paths. Adding new agent files requires config updates. labeler.yml:99-201
Low Consistency Issue labeler uses actions/github-script@v7 while other workflows use pinned SHA references. label-issues.yml:36

Recommendations

  1. Clarify workflow coexistence: Document whether label-issues.yml replaces or supplements ai-issue-triage.yml. If supplement, consider different trigger conditions to avoid duplicate runs.

  2. Standardize token usage: Use GITHUB_TOKEN for both workflows unless BOT_PAT is required for specific cross-repo operations.

  3. Extract issue labeler script: Move inline JavaScript to .github/scripts/label-issues.js for testability and reuse.

  4. Pin action versions: Replace actions/github-script@v7 with SHA-pinned reference for supply chain security consistency.

Verdict

VERDICT: PASS
MESSAGE: Well-structured static labeling implementation. Minor concerns around workflow overlap and inline script maintainability do not block merge.
QA Review Details

Now I need to check if there are any tests for these workflow files and understand the testing infrastructure in this repo.

Let me check for any existing validation workflows or tests for GitHub Action workflows:

Let me also check for any security-related patterns in the workflows (particularly the use of secrets.BOT_PAT in the issues labeler):

Now let me verify my understanding of the changes and check if there are any other workflows that might relate to this feature (like existing AI triage that this is meant to replace):

Now I have a complete picture. Let me compile my QA review.

LOW Missing regex anchor validation labeler.yml:219-230 Branch patterns use ^ but no $ anchor Verify behavior is intentional

Regression Risk Assessment

  • Risk Level: Low - These are additive workflows that do not modify existing functionality
  • Affected Components:
    • .github/workflows/label-pr.yml (new)
    • .github/workflows/label-issues.yml (new)
    • .github/labeler.yml (new)
  • Breaking Changes: None - existing ai-issue-triage.yml remains active
  • Required Testing: Manual testing of label application on test PRs/issues

Security Review

Check Status Notes
Secrets usage [PASS] Uses secrets.BOT_PAT for issue labeling (consistent with existing workflows)
Input validation [PASS] Issue title/body are lowercased before regex matching
Injection risk [PASS] No shell command execution, only GitHub API calls
Permissions [PASS] Minimal required permissions (contents: read, pull-requests: write / issues: write)
pull_request_target [WARN] Used for PR labeler - safe here since only reading file paths, not executing untrusted code

Workflow Logic Review

label-pr.yml

Check Status Notes
Trigger events [PASS] pull_request_target with appropriate types
Bot exclusion [PASS] Skips dependabot and github-actions bots
Concurrency [PASS] Uses PR number for group isolation
Timeout [PASS] 2 minute timeout appropriate for labeler
sync-labels: false [PASS] Prevents accidental label removal

label-issues.yml

Check Status Notes
Trigger events [PASS] Includes title/body change detection for edits
Bot exclusion [PASS] Skips dependabot and github-actions bots
Concurrency [PASS] Uses issue number for group isolation
Deduplication [PASS] Uses Set to remove duplicate labels

labeler.yml

Check Status Notes
Glob patterns [PASS] Uses any-glob-to-any-file syntax correctly
Exclusion patterns [PASS] Documentation excludes agent/memory directories
Agent coverage [PASS] All 13 agents have label rules
Conventional commits [PASS] Branch patterns align with spec

Specific Pattern Concerns

// label-issues.yml:55 - May match unintended content
'agent-qa': /\bqa\b|\bquality assurance\b/
// "FAQ" does not match due to \b, but "Q&A" edge case unclear

// label-issues.yml:96-97 - Broad match on common words
if (/^\[?bug\]?:?|\bbug\b|\bbroken\b|\bfail(s|ing|ed)?\b|\berror\b/.test(content))
// "error" may match debug discussions, not actual bugs

Verdict

VERDICT: WARN
MESSAGE: Configuration-driven workflows without automated test coverage; manual testing documented as complete

EVIDENCE:
- Tests found: 0 for 3 new files
- Edge cases: Regex patterns untested (16 agent patterns + 10 area/type patterns)
- Error handling: No try/catch in JavaScript action
- Blocking issues: 0
- HIGH issues: 1 (missing tests for regex patterns)

Recommendations

  1. Accept with follow-up: PR is low-risk since it adds static labeling without modifying existing behavior
  2. Document test approach: Add integration test strategy for future workflow changes
  3. Consider regex test file: Create tests/label-patterns.test.js to validate regex behavior
  4. Monitor for false positives: Watch for mislabeled issues after deployment

Mitigating Factors

  • Workflows use established, well-tested actions (actions/labeler@v5, actions/github-script@v7)
  • Configuration is declarative YAML with limited logic surface area
  • Existing ai-issue-triage.yml provides backup intelligent labeling
  • sync-labels: false prevents destructive label removal
  • PR description states manual testing was completed
Architect Review Details

Design Quality Assessment

Aspect Rating (1-5) Notes
Pattern Adherence 4 Static config-driven approach is deterministic and maintainable
Boundary Respect 4 Workflows stay in orchestration layer; labeler.yml is pure config
Coupling 5 Minimal dependencies: standard GitHub Actions only
Cohesion 5 Each workflow has single responsibility (PR labels vs issue labels)
Extensibility 5 Adding labels requires only config changes in labeler.yml

Overall Design Score: 4.6/5

Architectural Concerns

Severity Concern Location Recommendation
Medium ADR-006 violation: 84 lines of JavaScript in workflow label-issues.yml:39-122 Extract to .github/scripts/IssueLabeler.psm1 module with Pester tests
Low Uses BOT_PAT secret but PR labeler uses GITHUB_TOKEN label-issues.yml:38 Document why different tokens required or unify
Low Regex patterns embedded in workflow are untestable label-issues.yml:48-106 Move patterns to JSON config or PowerShell module

Breaking Change Assessment

  • Breaking Changes: No
  • Impact Scope: None
  • Migration Required: No
  • Migration Path: N/A

Technical Debt Analysis

  • Debt Added: Medium (issue labeler logic embedded in workflow YAML)
  • Debt Reduced: Low (replaces AI-based triage)
  • Net Impact: Neutral

ADR Assessment

  • ADR Required: No
  • Decisions Identified: Static labeling replaces AI-based triage
  • Existing ADR: ADR-006 (Thin Workflows, Testable Modules) applies
  • Recommendation: No new ADR needed, but ADR-006 compliance required

Domain Model Alignment

Domain Concept Current Representation Proposed Change Alignment Status
Agent labels 13 agent types in labeler.yml File-path based detection Aligned
Area labels 5 area categories Path + branch patterns Aligned

Recommendations

  1. Extract issue labeler logic to PowerShell module per ADR-006. The label-issues.yml workflow contains 84 lines of JavaScript logic. Create .github/scripts/IssueLabeler.psm1 with Pester tests.

  2. Document token difference between GITHUB_TOKEN (PR labeler) and BOT_PAT (issue labeler) or unify if possible.

  3. Move regex patterns to configuration file for testability and maintainability.

Verdict

VERDICT: WARN
MESSAGE: PR labeler follows thin-workflow pattern. Issue labeler violates ADR-006 with 84 lines of embedded logic but is non-blocking for initial merge.
Security Review Details

Security Review Analysis

Findings

Severity Category Finding Location CWE
High Secret in Workflow Uses secrets.BOT_PAT instead of secrets.GITHUB_TOKEN label-issues.yml:38 CWE-522
Medium Workflow Injection pull_request_target trigger with write permissions on untrusted code context label-pr.yml:9-14 CWE-94
Low Overly Broad Regex Regex patterns in issue labeler may match unintended content label-issues.yml:49-107 N/A

Detailed Analysis

HIGH: BOT_PAT Usage (label-issues.yml:38)

The workflow uses secrets.BOT_PAT instead of secrets.GITHUB_TOKEN. Risk Score: 6/10.

  • If BOT_PAT has excessive scopes beyond issues:write, this creates unnecessary privilege escalation
  • BOT_PAT tokens typically persist longer than GITHUB_TOKEN
  • Recommendation: Use secrets.GITHUB_TOKEN unless BOT_PAT is required for specific functionality

MEDIUM: pull_request_target Trigger (label-pr.yml:9)

The pull_request_target trigger runs in the context of the base branch with write permissions. Risk Score: 5/10.

  • This workflow only uses actions/labeler@v5 which reads config from base branch
  • The workflow does NOT checkout PR code or execute PR-provided scripts
  • Current implementation is SAFE because labeler reads .github/labeler.yml from base branch
  • No code execution from the forked PR occurs

LOW: Regex Pattern Matching

The regex patterns are broad but acceptable for labeling purposes. False positives would only result in extra labels, not security issues.

Positive Security Observations

  1. Minimal Permissions: Both workflows use least-privilege permissions (contents: read, appropriate write scope)
  2. Bot Actor Filtering: Both workflows skip execution for dependabot and github-actions bots
  3. Concurrency Controls: Proper concurrency groups prevent race conditions
  4. Timeout Limits: 2-minute timeouts prevent runaway executions
  5. No Secret Exposure: No secrets are logged or exposed in outputs

Recommendations

  1. Consider replacing BOT_PAT with GITHUB_TOKEN in label-issues.yml:38 unless cross-repo permissions are required
  2. Document BOT_PAT scope requirements if it must be used

Verdict

VERDICT: WARN
MESSAGE: BOT_PAT usage instead of GITHUB_TOKEN creates unnecessary token scope exposure. The pull_request_target usage is safe in this implementation. Consider switching to GITHUB_TOKEN if full repo access is not required.

Code Review

This pull request introduces automated labeling for PRs and issues, which is a great enhancement for repository management. The implementation uses standard GitHub Actions (actions/labeler, actions/github-script) and includes a comprehensive configuration in .github/labeler.yml.

My review focuses on ensuring the new scripts and documentation adhere to the repository's style guide and best practices for robustness.

Key feedback points:

  • PowerShell Script: The new Invoke-BatchPRReview.ps1 script is well-structured but could be improved in terms of error handling for external commands and adherence to PowerShell verb naming conventions.
  • Markdown Documentation: The pr-review.md command documentation contains bash examples that should be updated to follow quoting best practices as defined in the style guide to prevent potential script errors.

Overall, these are solid additions. The suggested changes will improve the robustness and maintainability of the new automation scripts.

The regex patterns for agent detection could produce false positives. For example, the pattern /\bqa\b/ will match common words like "qa" but also trigger on phrases like "Q&A" or standalone "QA" in unrelated contexts. Similarly, /\bsecurity\b/ will match any mention of the word "security" even in general discussion. Consider making these patterns more specific by requiring additional context (e.g., "agent qa", "@Agent-QA", "qa agent") or by checking for multiple related keywords before applying the label.

Error handling in this function silences errors with 2>$null but doesn't provide enough context when the PR is not found. When $prInfo is null, the warning message is helpful, but the function should also check if the GitHub CLI is authenticated and available before attempting the query. Consider adding a preliminary check: if (-not (Get-Command gh -ErrorAction SilentlyContinue)) { Write-Error "GitHub CLI (gh) not found"; return $null } to provide clearer error messages when the tool is missing.

The Shell script examples in this documentation use incorrect Bash syntax for error checking. The pattern if [[ -n "$(git status --short)" ]] is correct Bash, but the earlier sections at lines 194-202 show a Python-style working directory approach that conflicts with the Bash examples here. Additionally, the script mixes Python (lines 27-35, 67-87) and Bash (lines 54-61, 94-125) code blocks without clearly indicating which language/environment should be used for execution. This creates confusion about the actual implementation. The documentation should either use consistent language throughout or clearly separate the pseudocode from actual implementation examples.

The error recovery table mentions "force cleanup" for agent timeout scenarios, but the actual implementation in the PowerShell script doesn't have a timeout mechanism for agent operations. The script's timeout handling is limited to the git operations and worktree management. If an agent process hangs or runs indefinitely, there's no automatic timeout or force cleanup mechanism implemented. Either implement the timeout handling referenced here, or update the documentation to accurately reflect what the current implementation does in timeout scenarios.

Suggested change
| Agent timeout | Log partial status, force cleanup |
| Agent timeout | No automatic timeout; if an agent hangs, log what you can and perform manual cleanup |

The critical constraints section references Python-style file path construction (line 211: file_path = f"{worktree_root}/.agents/sessions/session.md"), but the actual implementation is in PowerShell, not Python. The PowerShell script uses Join-Path for path construction (e.g., line 78 in Invoke-BatchPRReview.ps1). This inconsistency between documentation language and implementation language could mislead developers trying to extend or modify the system. Update the examples to use PowerShell syntax or clearly mark them as pseudocode.

The bug detection pattern has the same issue as the feature detection - the ^ anchor at the start of the regex will only match if "bug" appears at the very beginning of the concatenated title+body content. This means bug reports with "bug" mentioned in the body or later in the title won't be labeled correctly. The pattern should use word boundaries instead of start anchors to detect "bug", "broken", "fail", or "error" anywhere in the content.

Suggested change

The negation patterns in the documentation label configuration use incorrect syntax. The patterns !.agents/**/*.md and !.serena/memories/**/*.md attempt to exclude certain markdown files, but according to the actions/labeler@v5 documentation, negation should be specified using a separate all-globs-to-all-files matcher with negated patterns, not inline with ! prefix in any-glob-to-any-file. The current syntax may not work as intended and could either cause the entire rule to fail or be ignored. Use the proper negation structure with separate matchers instead.

git worktree add $worktreePath $branch 2>&1

The New-PRWorktree function doesn't properly handle the case where worktree creation fails. When git worktree add fails (line 86), the error is captured with 2>&1 and $LASTEXITCODE is checked, but the captured error output is not logged or displayed to the user. This makes debugging difficult. Consider storing the output: $output = git worktree add $worktreePath $branch 2>&1 and then logging it if the command fails: Write-Error "Failed to create worktree for PR #$PRNumber: $output".

Suggested change
git worktree add $worktreePath $branch 2>&1

The Remove-PRWorktree function uses git command output redirection 2>&1 but doesn't capture or display the error output when removal fails. Similar to the worktree creation function, when git worktree remove fails, users won't see the actual error message from git, making it difficult to diagnose why the removal failed (e.g., worktree locked, in use, etc.). Capture and display the git output on failure for better troubleshooting.

Suggested change
git @removeArgs 2>&1

Write-Error "Failed to remove worktree for PR #$PRNumber"
$gitOutput = git @removeArgs 2>&1

The commit message in the Push-WorktreeChanges function is hardcoded with a specific format. However, this may not follow the repository's conventional commit standards consistently. The message "chore(pr-$PRNumber): finalize review response session" uses a scope of "pr-$PRNumber", but according to conventional commits practices, scopes should typically be component names, not issue/PR numbers. Consider using a more standard scope like "chore(review)" or "chore(pr-review)" and including the PR number in the commit body instead, or document this deviation from convention if it's intentional.

Suggested change
git commit -m "chore(pr-$PRNumber): finalize review response session"
git commit -m "chore(review): finalize review response session" -m "Related to PR #$PRNumber"

* docs(adr): Session 86 - ADR-017 critic review (model routing policy)

Critic review of ADR-017 (Copilot model routing policy).

## Summary

ADR-017 proposes evidence-aware, tiered model routing to minimize false PASS verdicts.
Core decision is sound; execution requires additional specifics before deployment.

**Position**: Disagree-and-Commit with conditions

- Approve strategic direction (evidence-based routing, conservative verdicts)
- Defer tactical implementation to Phase 2 (baseline metrics, concrete examples, validation)
- Three P1 concerns resolve before deployment (metrics, examples, model confirmation)
- Estimated Phase 2 effort: 4-7 hours across metrics, examples, and CI guardrails

## Key Findings

**Strengths** (5):
1. Clear problem identification (summary-mode false PASS)
2. Conservative evidence-sufficiency principle is sound
3. Well-reasoned model matrix by prompt shape
4. Honest tradeoffs acknowledged
5. Governance safeguard (copilot-model parameter required)

**Gaps** (7):
1. Model claims lack validation (no vendor benchmarks)
2. Implementation incomplete (CONTEXT_MODE header not shown)
3. Success metrics aspirational, not measurable
4. Evidence improvement marked optional vs. required
5. No cost impact quantification
6. Prompt enforcement vague
7. No model deprecation policy

**Recommendations** (7):
1. Add baseline metrics and thresholds
2. Concrete examples (before/after workflows)
3. Clarify evidence improvement scope
4. Model validation plan with monitoring
5. Quantify cost impact
6. CI validation script for prompt rules
7. Model deprecation policy and fallbacks

## Phase 2 Implementation Plan

1. Merge ADR-017 as strategic decision
2. Add copilot-model parameter to composite action
3. Create follow-up task: Implementation Specifics (examples, metrics, CI)
4. Do NOT deploy workflow changes until Phase 2 complete

* docs(adr): ADR-017 Round 3 post-prerequisites debate - clarify scope and strengthen security

Session 90: Conducted multi-agent debate on ADR-017 after prerequisite completion.
Achieved consensus (5 Accept + 1 Disagree-and-Commit) with critical scope clarification.

## Critical Finding

The 3 baseline false PASS cases (PRs #226, #268, #249) were caused by prompt quality
and validation gaps, NOT by evidence insufficiency or model mismatch. ADR solution
doesn't address current 15% baseline—it targets FUTURE risk from large PRs with
summary-mode context.

## P0 Changes Applied (8 blocking issues)

1. **Root Cause Analysis**: Explicitly states ADR doesn't fix current baseline cases;
   targets future evidence insufficiency risks. Separates metrics:
   - Baseline false PASS (all causes): 15%
   - Target false PASS (evidence insufficiency): TBD (new metric)

2. **Baseline Methodology**: Clarified all 20 PRs validated (17 confirmed no fixes,
   3 had post-merge fixes). 7-day window is lower bound.

3. **Status Timeline**: Added chronology showing prerequisites completed BEFORE
   status change to Accepted (2025-12-23).

4. **Prompt Injection**: Changed from blacklist (bypassable) to whitelist/schema
   validation. Reject input not conforming to alphanumeric + common punctuation.

5. **CONTEXT_MODE Validation**: Added token count check to prevent manipulation.
   Workflow fails if claimed mode doesn't match actual context size.

6. **Circuit Breaker**: Prevents fallback DoS attack. If 5 consecutive blocks due
   to "forbid PASS" rule, escalate to manual approval with oncall alert.

7. **Aggregator Enforcement**: Added branch protection requirement for "AI Review
   Aggregator" status check. Prevents developer bypass.

8. **Cost Calculation**: Explicit math showing 36% reduction (568 → 366 Opus-eq
   units). Reconciles 20% escalation rate with routing savings.

## P1 Changes Applied (2 important issues)

1. **Success Metrics**: Updated baseline from "TBD (prerequisite)" to "15% (P0-1 complete)"
2. **Partial Diff N**: Defined N=500 lines (aligns with spec-file behavior)

## Debate Results

- **Rounds**: 3 total (2 initial in Session 86-88, 1 post-prerequisites in Session 90)
- **Consensus**: 5 Accept (architect, critic, security, analyst, high-level-advisor)
  + 1 Disagree-and-Commit (independent-thinker)
- **Independent-thinker dissent**: Skeptical evidence insufficiency is primary lever,
  but ADR now intellectually honest about scope. Supports execution for validation.

## Files Modified

- `.agents/architecture/ADR-017-model-routing-low-false-pass.md`: 10 sections updated
- `.agents/architecture/ADR-017-debate-log.md`: Round 3 entry added, metadata updated

* docs(adr): create ADR-018 establishing architecture vs governance split criteria

Session 90 follow-up: User questioned whether ADR-017 strictly adheres to
foundational ADR definition. Analysis revealed "single AD" criterion violation
(bundles 7 related decisions) and surfaced "Any Decision Record" debate.

## Problem

Ambiguity exists about when to use:
- `.agents/architecture/` (ADRs)
- `.agents/governance/` (operational policies)
- Both (split pattern like ADR-014 + COST-GOVERNANCE)

## Decision (ADR-018)

Establish explicit split criteria with three patterns:

### 1. ADR-only
- Affects system structure/quality attributes
- Primarily technical decision
- No ongoing enforcement required
- Example: API authentication strategy

### 2. Governance-only
- Operational policy/standard/process
- Does NOT affect architecture
- Requires compliance enforcement
- Example: naming-conventions.md

### 3. Split (ADR + Governance)
- BOTH architectural significance AND enforcement requirements
- Decision affects structure BUT requires ongoing compliance
- Policy evolves independently from architectural decision
- Example: ADR-014 (runner selection) + COST-GOVERNANCE (enforcement)

## Key Provisions

- **Decision matrix**: Classify by architectural impact + enforcement needs
- **Decision workflow**: Flowchart with 3 decision points
- **Real examples**: ADR-014 split (exemplar), ADR-017 (candidate for split)
- **Templates**: ADR and Governance policy templates in Appendix C
- **When to split**: Trigger criteria for retroactive splits

## Resolution of "Any Decision Record" Debate

**MADR movement**: Broadens ADRs to "Any" decision (design, process, governance)
**Critics**: Dilutes architectural focus, recommend separate records

**Our approach**: Hybrid
- Adopt "Any Decision Record" concept via governance/ directory
- Preserve architectural focus in architecture/ directory
- Use split pattern when both aspects exist

## Impact

- Resolves placement ambiguity for future decisions
- Recommends ADR-017 split into architecture + governance
- Establishes precedent for meta-ADRs (ADRs about ADR process)

## Files

- `.agents/architecture/ADR-018-architecture-governance-split-criteria.md` (new)
- `.agents/sessions/2025-12-23-session-90-adr-debate-clarification.md` (updated)
- `.serena/memories/adr-foundational-concepts.md` (updated with "Any Decision Record" debate)

* docs(adr): split ADR-017 into architecture decision + governance policy

Implements ADR-018 split pattern: separate immutable architectural decision from evolvable operational policy.

## What Changed

**Before**: Single bundled ADR-017-model-routing-low-false-pass.md (~550 lines)
- Mixed architectural decision with governance policy
- Violated 'single AD' criterion (bundled 7 related decisions)
- Policy changes required re-opening ADR debate

**After**: Split into focused documents

1. **ADR-017-model-routing-strategy.md** (architecture/, ~200 lines)
   - Immutable architectural decision
   - Focus: Why route models by prompt type + evidence availability
   - Contains: Context, Decision, Rationale, Alternatives, Consequences

2. **AI-REVIEW-MODEL-POLICY.md** (governance/, ~400 lines)
   - Evolvable operational policy
   - Contains: Model routing matrix, evidence sufficiency rules, security hardening, escalation criteria, aggregator enforcement, circuit breaker, monitoring
   - Can evolve without re-debating architecture

## Why Split (ADR-018 Criteria)

| Criterion | ADR-017 Analysis | Result |
|-----------|------------------|--------|
| Affects architecture? | Yes (routing affects system quality) | Architecture component |
| Requires enforcement? | Yes (MUST use copilot-model, branch protection) | Governance component |
| Tightly coupled? | Yes (routing + evidence + security + aggregator) | Split pattern applies |
| Policy evolves independently? | Yes (monitoring thresholds, escalation tuning) | Split benefits realized |

## Benefits Realized

- Architectural decision now follows 'single AD' criterion
- Governance policy can evolve without ADR debate
- Follows ADR-014 + COST-GOVERNANCE pattern (codebase exemplar)
- Clear separation: 'why we decided' vs 'how we enforce'

## Disposition

- Original bundled ADR-017-model-routing-low-false-pass.md preserved in git history
- Removed from working tree (replaced by split)
- ADR-017-debate-log.md updated with split documentation

Implements: ADR-018 Architecture vs Governance Split Criteria
Session: 90 (2025-12-23)

* chore(session-90): finalize session with split completion and memory storage
