How statement and proof provenance work

The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.

Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.

These labels describe origin, not correctness: citations and verification chips remain separate evidence.

Every tangent vector is the velocity of a smooth curve

Statement

Every tangent vector $v \in T_{p} M$ is the velocity of some smooth curve through $p$ .

Facts & Assumptions

Given: A tangent vector $v \in T_{p} M$ .

[L1]

Curve contact classes are canonically isomorphic to tangent vectors (Curve contact classes are canonically isomorphic to derivation tangent vectors).

Proof

technique · direct

1.1L1given

By [L1], the vector $v$ corresponds to some contact class of smooth curves through $p$ .

2.1L1step 1.1

Any representative of that contact class has velocity derivation equal to $v$ .

3.1step 2.1∎

Therefore $v$ is the velocity of a smooth curve through $p$ .
