An unguarded vector parses as a real artifact, so Fossil crosslinks it into every clone -- two check-ins, a technote, twelve sub-manifest slices and a phantom pair that sync chases forever. Each vector now carries a leading # block; rfc_vectors.zig strips it at comptime so callers still see the exact RFC bytes.

Background and the cleanup that follows: see wiki page 'rfc-vector-ledger'. closed check-in: 32ef56aaf4 user: dmestas tags: rfc-vector-guard

A complete SHA-1 name is shorter than max_hash_len, so it missed the full-width fast path and fell to the O(store) hex scan -- once per file under `ls --size` and `ls --long`. On tcl's tip the 545 SHA-1 named files cost ~54ms each against ~0.2ms for the 1,653 SHA3 ones.

The directory is ordered by raw digest, so a prefix's matches form one contiguous run. A binary search for the run plus a walk of it proves uniqueness rather than assuming it, which is what the SHA-1 case was surrendered to the scan for. Odd-length prefixes end mid-byte and keep the scan.

ls --size on tcl: 1.98s -> 0.03s. Issue #148. closed check-in: 4829f043b1 user: dmestas tags: fix-148-prefix-lookup

The cycle panic was in the indent computation, and rewriting it made the panic go away without my being able to explain the arithmetic -- 32*2 into a 64-byte buffer should not overflow. This asserts the bound directly, so the renderer's assumption is checked rather than believed. closed check-in: 5a35874240 user: dmestas tags: strata
