 - **Evidence** — how well-evidenced the claims are, on the same 1–5 scale. An essay with high importance and low evidence is a speculative position and should be read accordingly.

- **Trust score** — a single 0–100 integer derived automatically from confidence (weighted 60%) and evidence (weighted 40%, with the 1–5 scale rescaled so that evidence=1 contributes zero and evidence=5 contributes the full 40 points). It is deliberately *narrow*: it answers "how much should you trust the central claim?" and nothing else. It says nothing about how broadly the work matters, how novel it is, or how useful it is in practice — those are separate axes (see below) that are deliberately *not* folded into a composite, so a high trust score on a personal essay cannot be misread as "world-shaking." Following Gwern's lead, the orientations are presented in parallel rather than blended into a single index. The score is not entered manually and lives only in the epistemic footer.
+- **Overall score** — a single 0–100 integer derived automatically from the three quantitative fields above: confidence weighted at 50%, evidence at 30%, importance at 20%. It appears adjacent to the Epistemic link in the top metadata row and is not entered manually.

- **Scope**, **Novelty**, **Practicality** — orientation fields shown as their own rows in the epistemic footer alongside confidence, importance, and evidence. *Scope* ranges from *personal* to *civilizational*; *novelty* from *conventional* to *innovative*; *practicality* from *abstract* to *exceptional*. These are not ratings — they are orientations, and they intentionally do not feed the trust score.
+- **Scope**, **Novelty**, **Practicality** — optional qualitative fields in the expanded footer. *Scope* ranges from *personal* to *civilizational*; *novelty* from *conventional* to *innovative*; *practicality* from *abstract* to *exceptional*. These are not ratings — they are orientations.

 - **Stability** — auto-computed at every build from `git log --follow`. The heuristic: very new or barely-touched documents are *volatile*; actively-revised documents are *revising*; older documents with more commits settle into *fairly stable*, *stable*, or *established*. This requires no manual maintenance — the build reads the repository history and makes the inference.
