# kaal:position:2026-08-28-002

**Affirmed position.** Haber and Stornetta's 1991 linking scheme is a direct precedent for the integrity mechanism in Kaal's Chronicle claim. Their signed certificates carry hash-bound information from earlier certificates, a challenger may follow the sequence forward or backward, and retrospective insertion into the existing stream requires a hash collision. The precedent is narrower than Kaal's operational design. It does not specify a persisted per-tool head, separately evaluate deletion or reordering, establish a determinable break point, or prove a one-hash append cost. Protection also depends on independently held certificates or an external anchor when the local chain and head share one rewritable trust boundary.

**Status.** affirmed  **Published.** 2026-08-28

**Holds when.**

- Hash-linked time-stamp certificates, not Chronicle logs.
- Independent challenge or anchoring is required against wholesale rewriting.
- No support for the claimed one-hash append cost.
