Pre-Commit Review

Symbols

Sym	Meaning
Δ	set of changed symbols (from detect_changes)
P	affected execution processes
D1	direct dependents of each Δ member

O_review

O_detect {

1. tff-gitnexus_detect_changes({ scope: "staged" }) → Δ, P;
2. staged = ∅ → tff-gitnexus_detect_changes({ scope: "all" }) → Δ, P; } → {Δ, P}.

O_analyze { 3. ∀ m ∈ top5_risk(Δ): tff-gitnexus_impact({ target: m, direction: "upstream" }) → D1; 4. ∃ m ∈ Δ: |D1| > 3 → tff-gitnexus_context({ name: m }) → full context; } → {D1, context}.

O_report { 5. Output: Δ w/ locations; P — touched flows; D1 \ Δ — potential breakage; verdict ∈ {SAFE, REVIEW, RISKY}; } → review.

Rules

R1: staged → detect(staged); ¬staged → detect(all). R2: d ∈ D1 ∧ d ∉ Δ → flag_breakage(d). R3: process_crossing(Δ) ∧ ¬user_ack → ¬approve.
