Reverse the temporary rollback and restore the exact tree from 6c2c5a2. The following commit reapplies the Whiteboard 0.2.1 version fields. Agent-Session: fb96350b-c19e-48f0-b364-31e9ad2b72f4 Agent-Session: a7af3b88-3bb7-48a2-ae20-7626a83628a1 Agent-Session: ab10ae26-42f2-4ecd-86d0-79f5a9edecf0
Carry forward the production release version in product.json and the two package manifests after restoring the original diffr import snapshot. Agent-Session: fb96350b-c19e-48f0-b364-31e9ad2b72f4 Agent-Session: a7af3b88-3bb7-48a2-ae20-7626a83628a1 Agent-Session: ab10ae26-42f2-4ecd-86d0-79f5a9edecf0
Benchmark query compilation, full core/shape processing, and isolated context shaping with Criterion and bundled PR998 inputs. Document timing boundaries and plugin rebuild requirements. Imported from devdotfast/diffr#103. AI-assisted: OpenAI Codex.

A leaf's new `pair` field names the leaf on the other side with the same `alignment_id`, and is absent for an added or deleted leaf. Projection sets it as it numbers leaves, and a cut names each new tail's partner. diffr-ts and the TUI's wire schema accept the field. AI-assisted: developed with Claude Code.

`has_changes`, `is_one_sided` and change coverage asked whether a leaf is paired by collecting every alignment id on the other side, once per call. `paired_leaf` searched the other side for the matching leaf. They now read the leaf's `pair`. Test fixtures name pairs from their alignment ids. AI-assisted: developed with Claude Code.

Every lookup by id searched both trees. The cursor now keeps each region's side, parent and path from its side's root, so a lookup is a probe and a descent. `cut` and `join` rewrite the entries of the regions they move. The sides become private so nothing else can move a region; the plugin host takes them back with `into_sides`. No behavior change. AI-assisted: developed with Claude Code.

`linked_regions`, `set_collapsed` and `link` walked both trees to find the regions in a fold state. The cursor now keeps the regions of each fold state, and `cut`, `join` and `link` update it.

`startup/one_file` compiles the default queries, then diffs and projects one fixture: what a run pays before its first result. AI-assisted: developed with Claude Code. Agent-Session: fb96350b-c19e-48f0-b364-31e9ad2b72f4 Agent-Session: 01a1196d-bad4-7f61-bafc-f63d12217676 Agent-Session: 7d7ac281-cc4b-4437-9e1e-3872651e8bcf Agent-Session: a7af3b88-3bb7-48a2-ae20-7626a83628a1
Startup compiled the fold and context queries of every language before diffing the first file. `Params` now keeps each language's assembled sources and compiles them the first time that language is diffed. A query that does not compile no longer fails the run at startup. It fails each file in its language with a `query_error`; files in other languages diff as usual. Reading query files and resolving their imports still happens at startup. AI-assisted: developed with Claude Code.

Bun 1.3.10 on Linux reads process.ppid once and never again. The TUI's watchdog compares it with the parent it started under, so a released Linux TUI keeps running after its launcher is killed without a hangup. Bun 1.3.14 reads it each time. The Bun type declarations move to 1.3.14 to match.

Stacked on #1016.
The diffr workflows now use Bun 1.3.14 instead of 1.3.10, in CI and in releases.
On Linux, Bun 1.3.10 reads
process.ppidonce and never updates it. The terminal UI (TUI) uses that value to notice when the program that started it is gone. So a released Linux TUI keeps running after its launcher is killed with SIGKILL. Bun 1.3.14 reads the value each time.The Bun type declarations (
@types/bun) move to 1.3.14 too.Testing
In a Linux container, the TUI's
shutdown.test.tsfails with Bun 1.3.10 and passes with 1.3.14. CI doesn't run the TUI tests on Linux yet; #1019 adds a job that does.
