Write or rewrite a document in evidence-locked mode: no unsourced sentences — every substantive claim carries a footnote citing the exact passage in the user's provided sources, and anything unsupportable is explicitly marked. Use when asked to make a document fully sourced, add citations from my docs, ground a draft in the attached material, or produce something for audiences that will check (legal, board, regulators, enterprise buyers). Produces the document with numbered citations, a source map quoting each cited passage, and an unsupported-claims register.

Evidence Lock Skill
For most drafts, plausible is enough. This mode is for the documents where someone will check: every substantive sentence either cites the exact passage in the user's sources that supports it, or wears an explicit [UNSOURCED] flag. No third state.
What This Skill Produces
The document, with numbered footnote markers on every substantive claim
A source map: each footnote → source name + the supporting passage quoted verbatim
An unsupported-claims register: every [UNSOURCED] item with what evidence would resolve it
A coverage score: % of substantive claims that are locked
Required Inputs
Ask for (if not already provided):
The sources — pasted documents, files, or excerpts. This skill cannot run without them; general knowledge is not a source here.
The task — either a draft to lock (rewrite mode) or a brief to write from scratch (compose mode)
Strictness — hard lock (unsupported claims are removed to the register) or soft lock (they stay in the text, flagged [UNSOURCED]). Default: soft.
Locking Method
Index the sources first. Skim all provided material and note what each source can support. If sources are thin relative to the task, say so up front — don't compensate with fluency.
Classify each sentence while writing:substantive (factual claim, number, attribution, causal statement) → needs a lock; structural (transitions, headings, statements of the document's own intent) → exempt. When in doubt, it's substantive.
Lock = quote-level, not document-level. A footnote cites the source and the passage: [3] → "Q2 churn analysis, §4: 'logo churn concentrated in accounts under $10k ACV (71% of losses)'". Citing a whole document is not a lock.
No stretching. The passage must actually support the claim as written — not a weaker cousin of it. If the source says "churn rose in Q2" and the draft says "churn is accelerating", that's [UNSOURCED] (or the sentence gets weakened to what the source supports — prefer weakening).
Conflicts surface, never average. Two sources disagreeing produces both citations and a visible note, not a blended number.
Inference is allowed but labelled. A conclusion derived from cited facts gets [inference from 2,5] — distinguishing sourced, inferred from sourced, and unsourced.
