The session-fixture-layout gate requires every session JSONL fixture in
the canonical packed layout (maximal delta runs per kind/block, as
migrate:packed-session-fixtures rewrites); the packChunks: false knob
violated that invariant and failed the snapshot job. Revert the knob and
canonicalize the recorded fixture instead: the live log's
eager-drain-packed rows migrate to the maximal-run layout a burst replay
reproduces, so the fixture stays replay-deterministic and canonical.
The scenario previously carried an authored fixture; W4 of #1119 review
requires a live transcript. Recording surfaced two composition bugs that
are fixed here alongside it:
- provider ids: the app and the replay catalog both named the old
'deepseek' provider, which no adapter registers; both now use
'deepseek-official'
- the live config lacked persistenceCompression: none, so record-mode
sessions were written zstd-compressed and could not be harvested
(the snapshot twin already forced plaintext)
Recorded logs also need deterministic replay:
- packChunks: false in both configs — the eager-drain batch boundaries
that split packed delta runs are timing-dependent, so a packed log of
a long reasoning stream cannot replay-match its live record
- the fixture's request/header config and request/context are normalized
to the replay-produced minimal shape (the live adapter logs model
capabilities llm-replay has no data for), and tool-result path
separators are canonicalized to '/' for the Linux golden
posixOnly is restored now that the fixture is recorded.
Boot the glob sampling scenario from a standalone ACP composition that exposes only bash, glob, and grep. Regenerate the smaller header fixtures and trim implementation narration already owned by the Agent Note.
