Each --arm now names name=<checkout>@<full sha>. The harness refuses an arm whose HEAD
differs, whose product sources are dirty, whose renderer build-commit stamp is not that
HEAD, or whose sources changed after the build, and records that provenance in every
result. A cached seed from another seed-arm commit is refused, and report-only refuses to
mix results from different pins, seeds or recipes. Tables name full SHAs and disclose that
writer BEGIN-to-COMMIT spans are not observed.
The 4a stub speaks Claude stream-json, whose adapter writes no diff items, so
completed diff originals were a skipped row. The seed now appends known
diffs once into its last filler chat through the seed arm's own original
journal writer, after that arm stops and before the seed is renamed or
copied, so every arm starts from the same rows and item IDs. Both arms verify
kind, original length, a short page head and the exact patch from detail
before timing the tail page and the detail read, and the conversion sweep
reports the diff chat apart from the small chats.
The protocol bundle imported from './src/shared/agent-session/...', a folder
the path-literal ratchet reads as an unresolved import. Each module is now a
tracked-file constant joined onto the arm's own checkout, the same form
runtime-file-watcher-resource-probe.mjs uses; the bundle and its exports are
unchanged.
Renderer times and tab ids from waitForFunction handles go through typeof
guards, the visibility probe is a declared Window global, the runtime call
keeps its own typed response, and cached manifests, Electron paths, profiles
and families are narrowed by guards. The empty `import type {}` blocks name
AppStore and use it. Three casts remain, each with a line-specific SAFETY:
the generic RPC result and Node's performance inside main-process callbacks.

Conversion: seed a medium chat (310 chats on the full profile) and refuse a
cached seed from another recipe. Observe the candidate's existing
epoch-installed ready boundary with a read-only poll of journal_chat_state.
An idle seed copy yields launch to every chat ready and the per-size
ready-mark intervals; the families copy verifies an unconverted first open and
waits for every chat ready before any steady-state family.
History/detail: the stub emits ordinary Claude subagent frames (interleaved
and sparse-root corpora) and a shapes turn (huge completed tool originals, one
above the detail reply cap, an oversized ordinary message). Each named shape is
verified through the real history/detail route before its samples count; diff
items stay explicit missing evidence because the Claude adapter writes none.
Maintenance: write and rewind large completed rows on a disposable seeded chat
under a held outside reader, then measure other-chat sends during the hold,
after release and while freed pages are reclaimed, from read-only page/WAL
state. Retired-epoch pruning is skipped unless such rows are observed.

One entry (native-chat-4a-comparison.ts) seeds the 55k-history/310-chat
profile once through the seed arm, clones it per arm at a fixed path,
launches each built checkout in the background with an isolated home,
and drives the same stub provider events through the host RPC surface
both builds serve. Envelopes come from each arm's own source bundle.
Rows cover send/queue, 1/8/16 MiB streams with a competing send,
maintenance windows, open/reopen, history/detail, outline/fork,
rewind, record operations, R3 retained-history admission and, reported
separately, first-launch conversion (optional 20 GiB source). Output is
one JSON and one markdown table keyed by both head SHAs.
