Normalize tool tokens and clarify timing (#34)

- Normalize canonical tool tokens (c72c4734a9d620d47a14ad226857103d059625f3)
- Clarify nominal capture interval (2e55fe17110886146fe2ad9b33d3a2f8a1fc7b65)
- Limit tool-token rule to Standard (fdf7681b3503c52b071da9e70025617136a5e1d8)

 # Changelog
 
+## Unreleased — canonical tool-token and timing clarification
+
+- Corrected five active Standard paths whose tool tokens contradicted their
+  metadata: three `BallpoinPen` typos, one split `Ballpoint.Pen` token, and one
+  split `Fountain.Pen` token.
+- Retained every existing `record_id`, media payload, Xet identity, byte size,
+  and technical metadata. This is a server-side path normalization, not a
+  re-encoding or new recording.
+- Added validation requiring each declared Standard tool to appear as an
+  exact, case-sensitive filename token. Tool and medium lists remain
+  independent; no positional pairing is inferred.
+- Left revision-pinned historical relationship sidecars unchanged because
+  their earlier paths remain correct evidence at their declared revisions.
+- Clarified that 0.2 seconds is the Standard protocol's nominal capture
+  setting, not a confirmed per-record measurement or calibrated real-time
+  basis.
+
 ## Unreleased — verification and documentation consolidation
 
 - Clarified that each active metadata row represents one published video
