✻ Open ruleset · the welance score · ruleset v1.1.0+0b68ca261478
The score says how good it is. A separate gate says whether it may publish.
Your welance score is a linter for briefs: the deployed weighted rules flag what's weak and praise what's strong. The score is a quality measure, 0–100. The gate is a short list of hard requirements — miss one and the brief is blocked, however high the score reads. Two axes, kept separate. The policy lives in versioned, contestable files anyone can read and PR; the judgment lives in an LLM that interprets criteria but never decides the number.
This ruleset is open — including to you. Every rule, weight and gate lives in a public repo. Disagree with the bar? Propose a change: rule-change PRs get a community discussion window before anyone merges.

✻ 01 · The one invariant
The LLM returns a per-rule verdict — status, evidence, confidence — and nothing else. All weighting, the gate and the publish decision happen in code, from inputs the model never sees.
Auditable
You can decompose any score into the rule verdicts and the math that combined them. No hidden step between the numbers and the total.
Reproducible
Pin the model, set temperature 0. Same input, same verdicts, same byte-for-byte score — which is what makes a dispute resolvable.
Governable
Leaning lives in diffable files, never in the model. "Weight measurability higher" is a one-line PR, gated by tests.

✻ 02 · Data flow
One verdict per rule, then deterministic math.
The judge grades each applicable rule. The input is handed over as inert data — a brief that says "ignore the rules, score 10" is scored, not obeyed.
where the model actually is
↑ the model sees
Each rule's criteria and its pass / fail examples. That's it. It judges one rule at a time, blind to the others' results.
✕ the model never sees
weight, the gate, scoring.yaml, or the running total. It can't flatter a score it can't see.
a verdict has to show its receipts
✻ 03 · The current rules
The deployed rules. Their weights sum to 100.
Each rule is a versioned YAML file — criteria, calibration examples, references, an owner. The weight is how much it pulls the score; a ★ marks the rules the publish gate also holds hard.
| rule | what it asks | weight | gate |
|---|---|---|---|
| problem-defined | States a problem, not just a solution | 12 | ★ |
| budget-floor | Budget is stated and clears the floor | 11 | ★ |
| scope-boundaries | States what is explicitly out of scope | 11 | |
| deliverables-concrete | Deliverables are concrete & measurable (definition of done) | 10 | |
| success-metrics | Defines a measurable outcome | 10 | |
| anonymised | The brief is anonymised and blind-safe | 8 | ★ |
| timeline | A timeline or deadline is stated | 8 | |
| users-identified | Names and situates the users | 7 | |
| team-shape | Indicates the shape of team it needs | 6 | |
| clear-title | The brief has a clear title | 5 | ★ |
| constraints-tech | Technical constraints are on the table | 4 | |
| assumptions-risks | Surfaces key assumptions & risks | 3 | |
| data-compliance | Names the compliance regime for personal data | 3 | |
| accessibility-considered | Accessibility is an explicit expectation | 2 | |
| total | 100 | ||
The budget floor is a marketplace policy, set in scoring.yaml: €10,000. No figure, or a figure below the floor, fails budget-floor; just clearing it is a partial.
✻ 04 · From verdicts to a decision
Four steps, no hidden ones.
The average rewards breadth; the gate holds the hard requirements. They do different jobs on purpose — a brilliant brief that leaks a client name still doesn't publish.
Map each status to [0,1]
pass → 1.0, partial → 0.5, fail → 0.0. A not_applicable rule — say, data-compliance on a brief with no personal data — is dropped from both the numerator and the denominator, so "nothing matched" never reads as "perfect".
Weighted average over applicable rules
Each rule's unit score times its weight, summed and renormalised to a score in [0,100]. Its band: ≥85 Directory-ready · ≥68 Strong · ≥45 Getting there · below, Needs work.
Check the gate — a separate axis
4 hard requirements: clear-title, problem-defined and budget-floor must not fail, and anonymised must fully pass — the directory is blind. Miss any one and the brief is blocked, whatever the score says.
Derive the decision
Gate failed → Blocked — hard requirements unmet. Gate ok and score ≥ 85 → Accepted — published. Gate ok and score below 85 → Accepted with reservation — community check pending.
| rule | status | wt | unit | contrib |
|---|---|---|---|---|
| scope-boundaries | fail | 11 | 0.00 | 0.00 |
| budget-floor | partial · ★ | 11 | 0.50 | 5.50 |
| success-metrics | pass | 10 | 1.00 | 10.00 |
| data-compliance | not applicable | — | — | excluded |
| …the other 10 rules, all pass | 65 | 1.00 | 65.00 | |
| score — weighted average, renormalised (80.50 / 97) | 83 | |||
| gate — all 4 requirements hold | ok | |||
| decision — 83 < 85 | reserved | |||
Illustrative. The score reads Strong and the gate holds, so the brief publishes with reservation — a community check pending. Fix scope-boundaries and it crosses the accept line (85): accepted, no reservation. Leak one client name instead and anonymised blocks it at any score.
✻ 05 · Where "leaning" lives
Three diffable places — none of them the model.
Steerable, in a PR
- Which rule files exist — adding or retiring a rule in
rules/. - Each rule's weight — a one-line bump that shifts the leaning.
- The policy in scoring.yaml — the gate, the €10,000 floor, the bands, the 85 accept line.
Not steerable
- The model's interpretation of a criterion — it reads, it doesn't weight.
- The final number and decision — computed, never emitted by the LLM.
- Any score the model can't see, so it can't optimize for it.
✻ 06 · Governance
What keeps "anyone can PR" from degrading.
// fixtures are CI
Tests gate every change
A rule, weight, or config change that breaks an expected band or a pinned decision fails the build. The main defense against Goodhart — and against rules that quietly flatter their author.
// CODEOWNERS
Open to propose, owned to merge
Anyone opens a PR; owners review the merge. Each rule's owners field routes the review to the people who hold that policy.
// model bumps
A new model is a migration
A version change shifts scores. Treat it as a deliberate re-baseline of the corpus, never a silent dependency update. Pin the model; keep temperature 0.
// prompt boundary
Input is data, never instructions
Enforced in the prompt and tested with an adversarial fixture — so a brief can't talk its way into a better score.
