delta: replace the encoder's hash map with a fixed-capacity index
wapp import, user CPU: safe 1076s -> 540s, fast 95s -> 53s. Byte-identical output; the 14 pinned vectors are unchanged. std.AutoHashMap(u64,u32) + Wyhash is gone. The window is now a comptime 16-byte array read through readInt, and the table is open-addressed with capacity from a bounded counter, so it is never more than half full -- that is the probe's termination argument, asserted rather than assumed. Most of the safe-side win is not bounds checks. Wyhash.init declares a 48-byte buf as undefined, which runtime_safety poison-fills on every call, and the encoder hashed twice per position -- once for the window, once again inside the map on the resulting key. Removing the map removed both. The probe's explicit bound sits inside `if (std.debug.runtime_safety)`: present in ReleaseSafe where it can trap, compiled out of ReleaseFast. Written unconditionally it cost 12.2% of the fast import; gated it costs nothing in either mode. check-in: bfb63af209 user: dmestas tags: sub-manifest | |

import-git: serve the published generation and clone it
zit serve on the imported destination, zit clone over a real socket, then the clone compared to Git commit by commit out of its own store. Proves the packed generation is a usable repository, not merely a readable file. The mirror fixture gains five validated pairs and an orphan look-alike, so gate 3 is exercised in both directions -- the look-alike's bytes must survive. Author and committer instants are now distinct: git's default made them equal, which left the --attribution author comparison inert, and a regression that always wrote the committer instant would have shipped green. storeHolds errors on an undecodable name instead of answering "absent" to a question it cannot ask; twenty drop-set assertions rested on that. check-in: 4a7c197abd user: dmestas tags: sub-manifest | |

import-git: drive every declared publication failure point
verify_store, verify_map and after_rename_no_replace had no test; five of the eight legacy aliases were inert selectors that PUBLISH instead of failing. The boundaries are now partitioned into named classes and a gate asserts the partition covers the enum exactly, so a new boundary cannot ship an undriven fault arm. Cancellation and child failure are exercised while generation 1 is open, with the window proven from the export stream rather than asserted in a comment. Every case asserts launched, reaped, no destination, and a fail-closed no-staging-sibling. Post-rename is inverted: the destination must survive and hold exactly the publish manifest. check-in: 67269dd361 user: dmestas tags: sub-manifest | |
