cascade-dedup

# Cascade dedup The cascade family replicates one canonical prompt across three harnesses. Dedup means: verify the intentional replication byte-for-byte, strip the accidental repetition, and resolve conflicts with the canonical as winner. | File | Role | Zones | |---|---|---| | `/home/alpha/.claude/claude/system-prompt-baseline.md` | Canonical; wins every conflict | Whole file is the source of truth | | `output-styles/{axiom-mode,builder,duet,linus,odin,benchmark}.md` | Style embeds | Persona prefix **above** the charter `<role>` (the second `<role>` per file) = strip zone. Tail **from** the charter `<role>` = byte-identity invariant zone, never a dedup target | | `output-styles/benchmark.md` auto-gen preamble (margin-runner header) | Generated | Never touch. Repairs to benchmark.md's cascade tail require explicit user authorization first | | `/home/alpha/.omp/agent/AGENTS.md`, `/home/alpha/.codex/AGENTS.md` | Harness embeds | Harness-adapted tool sections are legitimate divergence; targets are internal duplication and accidental drift. Outside the repo: editable, never committable | ## Step 1 — Verify the invariant before dedup Extract the canonical: `cp system-prompt-baseline.md /tmp/canon.md` (its charter `<role>` is line 1, so the canonical is the whole file). Per output-style: ```bash diff -q /tmp/canon.md <(tail -c "$(wc -c < /tmp/canon.md)" output-styles/X.md) ``` Drift here is a sync bug, not duplication. Repair means replacing the file's entire tail (from its c...
