docs(research): consolidate GC/pooling round into phase-0
- iroh-blobs GC mechanics verified against current checkout:
mark-and-sweep (named tags + TempTag RAII + ProtectCb with abort),
format-aware mark traversal, DeleteSet write-safety, no namespaces
(flat tags) — our namespace concept maps onto their machinery
- rudolfs prior art section: StorageKey(ns, oid) composite key +
decorator storage stack; THE ANTI-PATTERN inverted (physically
namespaced storage defeats cross-tenant dedup); list() is
load-bearing; verify-as-decorator; streaming LFSObject + fanout
- OQ-BL-03: oid<->hash mapping DISSOLVED — git's oid derivation is
itself a hash algorithm (domain-separated preamble); per-algorithm
namespaces; mapping only reappears for transfer-vs-storage hashes
- OQ-BL-05 consolidated: physically flat/logically namespaced; tags
are the root table; references stay above the crate; mark-and-sweep
with protect-callback lean (a) + TempTag pinning; traversal
ownership (a/b/c) is the Phase 1 ADR
- POC register updated: #1 adds list() completeness + pinning
contract, #2 reframed as validating oid-dissolution, #4 as the GC
worked example; 'what each POC decides' section added
