Pre-consolidation analysis for observability/audit workflow overlap

[Copilot]

Adds two scratchpad reference documents capturing the pre-consolidation state before any workflow or expression-subsystem merging begins.

scratchpad/observability-audit-consolidation.md

Pre-consolidation analysis of the five overlapping observability/audit workflows (Kit, Audit, DOR, WHM, SOH):

• Table 1 — What each workflow analyzes across 16 dimensions (data model, time window, episode model, firewall/MCP/safe-output/portfolio coverage, chart generation)
• Table 2 — Configuration snapshot (engine, strict, timeout, tools, permissions, tracker-id)
• Table 3 — Output artifacts (discussions, escalation issues, charts, repo/cache-memory writes)
• Table 4 — Import dependency matrix
• Table 5 — KEEP vs. CONSOLIDATE overlap map with preference winner per capability
• Table 6 — Six specific conflicts requiring resolution, including the [observability] discussion prefix collision where DOR's daily close-older-discussions silently kills Kit's 7-day report
• Table 7 — Engine selection rationale and downgrade candidates (DOR is strongest: file-presence checking doesn't need a reasoning-heavy model)
• Table 8 + Appendix — Four distinct concerns mapped to owners, plus per-workflow unique-signal inventories

scratchpad/expression-consolidation.md

Pre-consolidation analysis of the pkg/workflow expression subsystem:

• File inventory (9 production files, ~2,896 lines; 8 test files, ~4,500 lines) with responsibilities
• Regex duplication map: 9 private duplicates in expression_safety_validation.go and 2 in expression_syntax_validation.go — all byte-for-byte identical to patterns already in expression_patterns.go
• Startup cost table: ~38 compiled regexes today vs. ~27 after consolidation (11 wasted compilations)
• Dependency graph across all 9 expression files
• Optimizer rule table (18 boolean-algebra rules with safety constraints)
• 3-step consolidation plan with explicit rename tables and risk assessment (no behavioral changes, no test changes needed)
