+# Pre-Publish BLOCK Issues: Fix ALL Before Release
+
+Two independent pre-publish reviews (Opus 4.6 + GPT-5.4) both concluded **BLOCK -- do not publish**. You must fix ALL blocking issues below using UltraBrain parallel agents. Work TDD-style: write/update tests first, then fix, verify tests pass.
+
+## Strategy
+
+Use ultrawork (ulw) to spawn UltraBrain agents in parallel. Each UB agent gets a non-overlapping scope. After all agents complete, run bun test to verify everything passes. Commit atomically per fix group.
+
+---
+
+## CRITICAL BLOCKERS (must fix -- 6 items)
+
+### C1: Hashline Backward Compatibility
+**Problem:** Strict whitespace hashing in hashline changes LINE#ID values for indented lines. Breaks existing anchors in cached/persisted edit operations.
+**Fix:** Add a compatibility shim -- when lookup by new hash fails, fall back to legacy hash (without strict whitespace). Or version the hash format.
+**Files:** Look for hashline-related files in src/tools/ or src/shared/
+
+### C2: OpenAI-Only Model Catalog Broken with OpenCode-Go
+**Problem:** isOpenAiOnlyAvailability() does not exclude availability.opencodeGo. When OpenCode-Go is present, OpenAI-only detection is wrong -- models get misrouted.
+**Fix:** Add !availability.opencodeGo check to isOpenAiOnlyAvailability().
+**Files:** Model/provider system files -- search for isOpenAiOnlyAvailability
+
+### C3: CLI/Runtime Model Table Divergence
+**Problem:** Model tables disagree between CLI install-time and runtime:
+- ultrabrain: gpt-5.3-codex in CLI vs gpt-5.4 in runtime
+- atlas: claude-sonnet-4-5 in CLI vs claude-sonnet-4-6 in runtime
+- unspecified-high also diverges
+**Fix:** Reconcile all model tables. Pick the correct model for each and make CLI + runtime match.
+**Files:** Search for model table definitions, agent configs, CLI model references
+
+### C4: atlas/metis/sisyphus-junior Missing OpenAI Fallbacks
+**Problem:** These agents can resolve to opencode/glm-4.7-free or undefined in OpenAI-only environments. No valid OpenAI fallback paths exist.
+**Fix:** Add valid OpenAI model fallback paths for all agents that need them.
+**Files:** Agent config/model resolution code
+
+### C5: model_fallback Default Mismatch
+**Problem:** Schema and docs say model_fallback defaults to false, but runtime treats unset as true. Silent behavior change for all users.
+**Fix:** Align -- either update schema/docs to say true, or fix runtime to default to false. Check what the intended behavior is from git history.
+**Files:** Schema definition, runtime config loading
+
+### C6: background_output Default Changed
+**Problem:** background_output now defaults to full_session=true. Old callers get different output format without code changes.
+**Fix:** Either document this change clearly, or restore old default and make full_session opt-in.
+**Files:** Background output handling code
+
+---
+
+## HIGH PRIORITY (strongly recommended -- 4 items)
+
+### H1: Runtime Fallback session-status-handler Race
+**Problem:** When fallback model is already pending, the handler cannot advance the chain on subsequent cooldown events.
+**Fix:** Allow override like message-update-handler does.
+**Files:** Search for session-status-handler, message-update-handler
+
+### H2: Atlas Final-Wave Approval Gate Logic
+**Problem:** Approval gate logic does not match real Prometheus plan structure (nested checkboxes, parallel execution). Trigger logic is wrong.
+**Fix:** Update to handle real plan structures.
+**Files:** Atlas agent code, approval gate logic
+
+### H3: delegate-task-english-directive Dead Code
+**Problem:** Not dispatched from tool-execute-before.ts + wrong hook signature. Either wire properly or remove entirely.
+**Fix:** Remove if not needed (cleaner). If needed, fix dispatch + signature.
+**Files:** src/hooks/, tool-execute-before.ts
+
+### H4: Auto-Slash-Command Session-Lifetime Dedup
+**Problem:** Dedup uses session lifetime, suppressing legitimate repeated identical commands.
+**Fix:** Change to short TTL (e.g., 30 seconds) instead of session lifetime.
+**Files:** Slash command handling code
+
+---
+
+## ADDITIONAL BLOCKERS FROM GPT-5.4 REVIEW
+
+### G1: Package Identity Split-Brain
+**Problem:** Installer writes oh-my-openagent but doctor, auto-update, version lookup, publish workflow still reference oh-my-opencode. Half-migrated state.
+**Fix:** Audit ALL references to package name. Either complete the migration consistently or revert to single name for this release.
+**Files:** Installer, doctor, auto-update, version lookup, publish workflow -- grep for both package names
+
+### G2: OpenCode-Go --opencode-go Value Validation
+**Problem:** No validation for --opencode-go CLI value. No detection of existing OpenCode-Go installations.
+**Fix:** Add value validation + existing install detection.
+**Files:** CLI option handling code
+
+### G3: Skill/Hook Reference Errors
+**Problem:**
+- work-with-pr references non-existent git tool category
+- github-triage references TaskCreate/TaskUpdate which are not real tool names
+**Fix:** Fix tool references to use actual tool names.
+**Files:** Skill definition files in .opencode/skills/
+
+### G4: Stale Context-Limit Cache
+**Problem:** Shared context-limit resolver caches provider config. When config changes, stale removed limits persist and corrupt compaction/truncation decisions.
+**Fix:** Add cache invalidation when provider config changes, or make the resolver stateless.
+**Files:** Context-limit resolver, compaction code
+
+### G5: disabled_hooks Schema vs Runtime Contract Mismatch
+**Problem:** Schema is strict (rejects unknown hook names) but runtime is permissive (ignores unknown). Contract disagreement.
+**Fix:** Align -- either make both strict or both permissive.
+**Files:** Hook schema definition, runtime hook loading
+

+
+## EXECUTION INSTRUCTIONS
+
+1. Spawn UltraBrain agents to fix these in parallel -- group by file proximity:
+   - UB-1: C1 (hashline) + H4 (slash-command dedup)
+   - UB-2: C2 + C3 + C4 (model/provider system) + G2
+   - UB-3: C5 + C6 (config defaults) + G5
+   - UB-4: H1 + H2 (runtime handlers + Atlas gate)
+   - UB-5: H3 + G3 (dead code + skill references)
+   - UB-6: G1 (package identity -- full audit)
+   - UB-7: G4 (context-limit cache)
+
+2. Each UB agent MUST:
+   - Write or update tests FIRST (TDD)
+   - Implement the fix
+   - Run bun test on affected test files
+   - Commit with descriptive message
+
+3. After all UB agents complete, run full bun test to verify no regressions.
