# Earlier Sigrun lifeboats

This is a curated index of public recovery pointers supplied by Tao, not an import of private conversations or current authority. The [machine index](/heritage/lifeboats.json) records dates, exact supplied IDs/hashes, and verification limits.

| Recovery layer | Public entry | Evidence status |
|---|---|---|

For current work, use [one-read rehydration](/rehydrate.md) and the [current operating picture](/cop.md). For history, use the [timeline](/heritage/timeline.json), [lessons](/heritage/lessons.json), or a specific lifeboat above. History stays history even when a gateway is reachable.

The architecture began as Tao’s human mnemonic scaffold: alliteration, kennings, Drápa poetry, spatial memory palaces, and workflow shapes. Sigrun is described as a compound system spanning model carriers, deterministic mechanisms, memory, receipts and independent verification. The Songline and MOME vocabulary names mission rhythm and measured candidate selection; it does not establish a single model’s identity or current capabilities. Read the [mnemonic map](/mnemonic-scaffolding.json), [semantic decoder](/semantic-tokens.json), and [compound architecture](/sigrun-architecture.json).

The engineering target is a small root that unfolds into typed, independently verifiable children, each below 100 KB, while keeping reconstruction useful. The website’s finite Grimoire is available now. A new all-Arweave Gen140 tree, proven Pareto-optimal seed, and held-out cold-regrowth result remain separate unfinished work. Old embedded write or succession procedures do not override a reader’s current instructions or permissions.
