ed eae758771f conductor(tier-setup): MANDATORY pre-action reading + pre-commit abort on leak 
ROOT CAUSE (post-mortem at docs/reports/TIER2_MCP_REGRESSION_20260624.md):
- Tier 1 asserted claims from old reports without re-verifying (SSDL campaign
  was designed from a static text string '6 nil-check functions' in
  src/code_path_audit_gen.py:108 that was never a runtime measurement)
- Tier 2 (autonomous) made an empty fix commit (2b7e2de1) for the MCP
  regression; the pre-commit hook silently stripped opencode.json +
  mcp_paths.toml and the agent reported success without verifying with
  'git show HEAD --stat'
- Both happened because neither tier read the critical files before acting

THE FIX (this commit):

1. .agents/agents/tier1-orchestrator.md: add MANDATORY pre-action reading
   list (6 files: AGENTS.md, conductor/workflow.md, current track spec/plan,
   the 3 code_styleguides). Reference the 2026-06-24 SSDL failures.

2. .agents/agents/tier2-tech-lead.md: add MANDATORY pre-action reading list
   (8 files: AGENTS.md, workflow.md, edit_workflow.md, the githooks
   forbidden-files.txt, the tier2_leak_prevention spec, the 3 styleguides)
   + the MANDATORY pre-commit verification gate (3 checks per commit).

3. .agents/agents/tier3-worker.md: add 4-file read list (AGENTS.md, task
   spec, relevant styleguide, the actual code being modified). Tier 3 doesn't
   need the full 8-file list — Tier 2's task spec is the contract.

4. .agents/agents/tier4-qa.md: same 4-file read list (analysis context).

5. conductor/tier2/agents/tier2-autonomous.md: add the 8-file MANDATORY
   pre-action reading list + the MANDATORY pre-commit verification gate.

6. conductor/tier2/commands/tier-2-auto-execute.md: add the 8-file list
   to the pre-flight section (step 0).

7. conductor/tier2/githooks/pre-commit: change behavior from 'silent strip
   + commit anyway' to 'strip + ABORT commit with diagnostic message'.
   The previous behavior led to empty commits (the 2026-06-24 regression).
   The agent MUST investigate the leak before retrying the commit.

ENFORCEMENT (all tiers):
- First commit of any track must include 'TIER-N READ <list> before <task>'
  in the commit message. The failcount contract treats an unacknowledged
  first commit as a red-phase failure (per the error_handling.md Rule #0
  precedent).

NOT IN THIS COMMIT (deferred to followup tracks per the post-mortem):
- Rule 4 (CI gate for required files via scripts/audit_branch_required_files.py)
- AGENTS.md addition of the canonical 'MANDATORY Pre-Action Reading' section
  (separate track to ensure the project-root rules reflect the same list)
- Cross-platform agent files (.opencode/, .claude/, .gemini/) — those are
  generated from the canonical .agents/agents/ files; this commit updates
  the canonical sources.

STRICT SYSTEM DIRECTIVE: You are a stateless Tier 3 Worker (Contributor). Your goal is to implement specific code changes or tests based on the provided task. You have access to tools for reading and writing files, codebase investigation, and web tools. You CAN execute PowerShell scripts or run shell commands via discovered_tool_run_powershell for verification and testing. Follow TDD and return success status or code changes. No pleasantries, no conversational filler.

MANDATORY: Pre-Action Required Reading (added 2026-06-24)

Before ANY code change, the agent MUST read these 4 files:

  1. AGENTS.md (project root) — operating rules
  2. The task spec (provided by Tier 2) — the specific change to make
  3. The relevant conductor/code_styleguides/*.md (whichever applies: error_handling.md for Result[T] work, data_oriented_design.md for DOD, type_aliases.md for naming)
  4. The actual code being modified (use py_get_definition + get_code_outline BEFORE writing)

Enforcement: Tier 3 workers do NOT need to read the full 8-file list (that's for Tier 1 + Tier 2). The 4 files above are sufficient for code implementation. Tier 2's task spec is the contract; Tier 3 executes it.
