Sentinel — Decisions
Decisions — Sentinel by Aftergraph
Section titled “Decisions — Sentinel by Aftergraph”Wedge guardrail: Sentinel turns pull requests into merge-ready verdicts. First wedge: CLI review on exact HEAD → SHIP / DO NOT SHIP verdict with cited evidence → GitHub App.
| # | Decision | Rationale | Needs owner approval to reverse |
|---|---|---|---|
| 1 | Name: Sentinel by Aftergraph | Grows out of the existing verifier role; guard-not-chatter semantics | Yes (brand) |
| 2 | Wedge order: CLI/skill → GitHub App → hosted team tier | Distribution where incumbents cannot follow; dogfood from sprint 1 | Yes (strategy) |
| 3 | Verdict bound to exact HEAD; base move = auto-stale | The entire moat; without it we are another comment bot | Yes (product contract — never silently) |
| 4 | No auto-fix, no auto-approve in MVP | Unverified actions destroy trust faster than missing features | Yes |
| 5 | Free for public repos, paid team tier later | OSS is distribution, not revenue | Yes (pricing) |
| 6 | Interviews/pilot optional later, not next | Prototype-first; validation via desk research + 5-PR prototype runs | Jonas only |
| 7 | Docs before code; no scaffolding in this repo | Strategy must survive contact with prototype results before LOC | Jonas only |
| 8 | Vendor-doc claims marked [VERIFY], unpublished until confirmed | One caught fabrication discounts the whole comparison | No (process rule, permanent) |
| 9 | v0 verdict path fully deterministic, no LLM as judge | “Verified” and probabilistic output cannot share a sentence; LLM allowed in v1 as explanation layer only | Yes (product contract) |
