timeline: --weekday, Ben Joffe's branchless day-of-week (#111)
An mtime divided by a day is already the day number Joffe's identity consumes (benjoffe.com/fast-day-of-week), so the UTC weekday falls out with no calendar decomposition. Flag-gated; unflagged output is byte-identical, pinned by test against a Sakamoto reference over 40,000 days. log --long's record grammar is now a stated contract: consumers parse it positionally and no display option will change it. The flag skips info, which prints no date line. check-in: 4652c5cc31 user: dmestas tags: trunk | |

crosslink: stream derived per-check-in records (#109)
The record body now captures the U-card user and the changed-file set, diffed against the primary parent at derive time where the parsed manifest is already in hand (layout 5, checkpoint 4; one-time rebuild per store). 'zit crosslink' replays it: identity, comment, tags, and file changes as a versioned text stream, cache-served under the same key discipline as every read verb, byte-identical to --no-cache. sqlite dumps 36,797 check-ins in 0.11s / 14.9MB against the 3.87GB structural stream. A parent the store does not hold reads as 'files unknown', never as an empty change set -- sqlite's corpus carries exactly one, a 2009 check-in with a genuinely absent parent. Mixed binary versions thrash across the layout bump: each side rejects the other's cache and re-derives. Update every binary that shares a store. check-in: 2a68d2fc79 user: dmestas tags: trunk | |

frames: --structural emits only what the crosslink links (#108)
Content blobs dominate a full stream (13.2GB on sqlite) and indexing consumers discard them. The gate is artifact.parseForImport on the reconstructed bytes -- never a cache -- behind an O(1) reject-fast screen that admits card shapes and signature wrappers; skipped frames are not hashed or emitted, and the cursor advances over them, so filtered and unfiltered polls compose against one cursor. sqlite 13.2GB -> 3.9GB, tcl -> 682MB. check-in: a2fb222e32 user: dmestas tags: trunk | |
