The runners are self-hosted but checkout cleaned the workspace, so every step recompiled the same sources into its own binary from nothing; unit tests and e2e were 6 and 4 minutes on the ARM64 critical path, mostly compile. Zig's cache is content-addressed, so it now lives outside the workspace and warms across runs, in both workflows. The toolchain tarball is kept the same way and still verified against the pinned digest every run. Also pins the tag-ignore trigger the previous commit introduced, which the workflow pin test had rejected. check-in: 3106100d42 user: dmestas tags: trunk

A release tag lands on a commit whose branch push already ran ci, and the tag push ran it again on the same three single-slot runners the release workflow was queueing for. Every branch push still runs; the release workflow, triggered by the tag, gates what it ships. check-in: e9e2ba4431 user: dmestas tags: trunk

The file-history index is built by the derive at ingest, fossil's way. check-in: 09d191e634 user: dmestas tags: trunk, version-0.3.18

fossil fills mlink as each check-in arrives and answers finfo by lookup. zit's derive computed the same row per check-in and dropped it; the index was rebuilt by a separate pass on the first PATH query, 6.8 min on pkgsrc and not resumable. The derive now hands each change set to an index builder as it links, stores it beside the checkpoint, and extends it over the tail on append; a cache hit computes nothing. The on-query build is the fallback and checkpoints every 8192 entries. Index format 4 records completeness so a partial checkpoint is never adopted whole. crosslink reports a tree's files instead of unknown. pkgsrc, fresh clone to first answer: 11.7 min -> 7.1 min + 1s. check-in: df99743ca4 user: dmestas tags: trunk

A push with no URL keeps its credential; the tree-manifest index build is proportional to what changed. check-in: dbfe2adebc user: dmestas tags: trunk, version-0.3.17

Two tree check-ins were diffed by flattening both to full file lists, files-per-check-in per check-in: 34 minutes once on a pkgsrc mirror. The S-card runs are now walked side by side, skipping every sub-manifest whose hash did not move and resolving only where it did. Deletes are held to the end so a moved partition key cannot make a live file look deleted. Trees flatten on demand only for the root and flat/tree pairings; the derive feed never flattens. pkgsrc: 34.3 min -> 6.8 min. check-in: ea4abe48fd user: dmestas tags: trunk

push --user U --password P with no URL parsed to a payload-less no_url, which the verb rebuilt as a bare empty URL, dropping the credential; the push went out anonymous and a peer requiring a login refused it. The parser now mirrors sync: an omitted URL is an empty one, resolved to the saved remote at run time, and the credential comes through. S12 asserts an authenticated no-URL push and a stored-login push both land on fossil. check-in: 4dba18d355 user: dmestas tags: trunk

File index works on submanifest stores; artifact shows S cards; a saved login authenticates a push that names no user. check-in: 8cfa57ecd3 user: dmestas tags: trunk, version-0.3.16

push --user saved the derived secret, but the resolver returned anonymous the instant --user was absent, so autosync (which pushes with no arguments) always went anonymous and a peer requiring a login refused it. With --user absent the saved login now stands in, never prompting; --user "" still forces anonymous. push, sync and config pull share the resolver. Whether such a push lands on a fossil peer is zit#196, a separate pre-existing matter. check-in: e37768d073 user: dmestas tags: trunk

On a submanifest store every check-in is a tree manifest, which the change-set capture refused as unknown, so the index recorded the whole log as unknown and a PATH query reconstructed per check-in anyway -- 39 minutes on a pkgsrc mirror. Trees now flatten inside the diff memo through the Repository seam, so the untouched diff sees a flat list; a tree that cannot be flattened stays unknown. Index format 2 -> 3 so a stale all-unknown blob is rebuilt once. check-in: 001c73defa user: dmestas tags: trunk

A tree check-in carries its file set entirely by S cards and the card renderer had no S lane, so it printed as a manifest with no files while ls on the same hash listed thousands. One lane, in card order, checked against --raw. check-in: da2598d1ca user: dmestas tags: trunk
