`--diff <base>..<head>` mines one range into `data.diff`: the changed-file set (the diff scope) with every added line bucketed verbatim / reshaped / new. Verbatim comes from git's own --color-moved=zebra; reshaped pairs the leftover adds against the leftover dels by token similarity. The scope dims everything it does not contain and gets the strata filter's "only" collapse; the Provenance mode paints inside it along a cyan -> violet -> orange "how much must I read" ramp. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
--no-renames so a renamed file's unchanged lines are counted as verbatim instead of vanishing from the diff; -c color.diff.* pins so a user's palette cannot break the parser; ---/+++ read as headers only inside a file header; blank and punctuation-only lines land in no bucket; warn when --diff head is not the checkout's HEAD. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A city carrying a diff now says so in every mode: refs as the user named them, changed-file count, substantive added lines; click = Provenance. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
DiffScope carries rev-list base..head plus base/head committer times; the spark draws the span as a cyan band with ref labels and tints the branch's own bars in the accent, everything else muted. setRange() pins both handles. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Modes may now change height, never footprint or position: in Provenance a diff file is its three origin bands (verbatim/reshaped/new) scaled by added lines, untouched files are plinths. Same instanced mesh via an optional BandSource; crossing the boundary rises over 300ms. Commit-type filter and "only the diff" go inert there. The chip and Provenance pin the strata range to the diff, so Strata's levels are the branch's commits. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…edOut core.quotePath=false — octal-escaped non-ASCII paths never matched the tree, so those files fell out of the diff scope; log.showSignature=false so a signed head still yields %ct. `--diff` with no value silently disabled the pass. movedOut was mined and typed but never read; MOVED_OLD still keeps git-matched deletions out of the reshaped pairing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…unts The collapse button only rendered once collapse was on, so nothing could arm it; it now stands in every mode but Provenance. Leaving Provenance via "Fix hotspots" kept the band geometry under a strata paint. setRange dropped its one-day drag floor (a sub-day PR pinned wrong) and gives up `rangeIsDiff` when an endpoint clamps; Escape only releases the pin where it is visible. Prov height scale and the legend file count come from files the city holds, not the repo-wide list. Docs carry the revised massing rule. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
