Magnus HedemarkandGitHub f9db3dbe4b fix(calculator): honest burn-multiple and runway labels, surface model assumptions (#274)
* fix(calculator): honest burn-multiple and runway labels, surface model assumptions

- Burn Multiple now reports Graham's metric (net burn / net new ARR);
  the net burn / MRR ratio is reported separately as Burn to Revenue.
  The qualifier (efficient/healthy/warning/critical) is derived from the
  real burn multiple, so DEAD verdicts no longer print 'efficient'.
- ALIVE verdicts no longer print a misleading 'Runway: 120 months'
  (projection cap); output now shows 'Projected cash-out' with 'none
  within the 10-year projection' when the company never runs out.
- Model assumptions (fixed/variable burn split, variable burn ratio,
  growth decay, projection cap, safety buffer) are now surfaced in the
  human report and in JSON model_assumptions.
- SKILL.md: fix dead paulgraham.com/default.html source URL to aord.html;
  update output-field docs and examples to real model output.
- Add regression tests (tests/integration/test_default_alive.py).

Fixes #272
Fixes #273

Default Alive / Default Dead Calculator

Evaluate whether a startup is on a trajectory to profitability before running out of cash. Paul Graham's Y Combinator framework as a deterministic CLI tool.

Why Install This Skill

When your agent loads this skill, it can run the single most important startup financial diagnostic. That means:

  • Compute default alive/dead status — will revenue reach profitability before cash runs out?
  • Calculate burn multiple — net burn vs net new ARR (the key efficiency metric)
  • Month-by-month projection — see the runway month by month
  • Identify levers — what changes would flip DEAD to ALIVE
  • Actionable verdict — ALIVE / DEAD / MARGINAL with next-step guidance
