build: compile for CI's Linux targets in the gate
This project links no libc and macOS links libc always, so a call that demands it compiles on a mac, passes every local lane, and refuses on both Linux runners -- the discovery order the fmt check already exists to prevent, and what zit#188 spent a red main on. `zig build cross` compiles the CLI for x86_64-linux and aarch64-linux and runs nothing; gate depends on it. Verified to discriminate: reintroducing std.c.getenv fails cross while a plain macOS build still passes. check-in: 31c4850b95 user: dmestas tags: trunk | |

log: read the file-index kill switch at main's environ seam, not through libc
std.c.getenv demands libc linkage, which this project does not take, so both Linux runners refused to compile while macOS -- which always links libc -- built it and the local gate passed. cli.Ambient.environ documents exactly this rule; the seam existed and was bypassed. Read $ZIT_NO_FILE_INDEX in main from init.environ_map like every other seam and hand the runner a flag. Cross-compiles clean to x86_64-linux and aarch64-linux. check-in: 1317aa9864 user: dmestas tags: trunk | |

log: answer a PATH filter from a file index, not by reconstruction (zit#188)
The predicate reconstructed a manifest per visited check-in, so one file's history on a mirror of SQLite cost minutes and grew with the history behind it. Persist what the derive already computes and throws away: captureFileFacts is Fossil's mlink row, so invert it by path into .zit-cache/finfo, keyed to the log tail and shun fingerprint like its sibling sidecars. The PATH walk now traverses the derived adjacency, as the unfiltered walk has since #98, and the index narrows it. The index only NARROWS: an F-card-level diff over-reports a delta that restates a path with the hash it already had (one check-in in 2,113 on SQLite), so every candidate is still confirmed by the B-log-2 predicate and the output is byte-identical. --long reads one manifest per emitted row instead of per visited node. README.md 72s to 1.6s, btree.c 25s to 1.1s, reconstructions 25,106 to 141. check-in: 17c3b0aaa2 user: dmestas tags: trunk | |
