+costs a host floor plus its context, so a reviewer that reads the whole diff and
+explores the repository pays for that context on every call (GSTA-152 measured a
+pass-1 specialist that explored at about 2.7M tokens, and one with a lean brief at
+0.23–0.51M). `gstack-review-packet build --base <base> --out-dir <dir>` takes
+`gstack-review-plan`'s flags, runs the same plan (`lib/review-plan-live.ts`) and
+writes one packet per `DISPATCH:` line holding:
+
+- the role's instructions and findings contract from `lib/review-prompts.ts`, the
+  strings the resolvers render into `/review`'s prose, so packet and prose cannot drift;
+- its checklist inlined (every `checklists=` entry for light depth's batched
+  specialist, each finding tagged with its checklist);
+- its `DIFF_CMD` diff at `-U8` against the literal diff base (`--range <sha>` from
+  pass 2 on), exclusions honored and untracked files included, under a stat; the
+  security specialist, the Red Team and the native adversarial pass see tests and
+  fixtures as a stat only;
+- at most 8 KB of `--plan-file`, and past learnings for specialists;
+- a read budget: at most 5 more reads of named ranges (200 lines at most) of files in
+  the diff, no repository search, no other packets, no transcript;
+- its output path and the reply `DONE <name> crit=<n> info=<n>`.
+
+A packet over 200,000 bytes is split by path into `<name>.1ofK` packets of the same
+reviewer, each with the whole instructions and checklist: no hunk is cut and no path
+dropped, and a hunk alone over the cap gets its own shard with a `SHARD_OVERSIZE` note.
+The Red Team's packet waits for the specialists (`--only red-team --findings
+<dir>/merged.jsonl`; until then collect lists it `pending`), the fix-check packet takes
+`--fix-list`, `--tests` and `--callers` with `--range $PASS_HEAD`, and `--audit
+test-coverage|plan-completion` writes a Step 7/8 audit packet from the generated
+section's prompt. An outside backend gets the outside-voice packet as its prompt file.
+
+`gstack-review-packet collect --dir <dir>` reads every output file and prints at most
+60 lines: one `REVIEWER:` line per packet (`clean`, `findings`, `missing`, `invalid`
+or `pending`), each CRITICAL on one line, and counts for INFORMATIONAL. It does Step
+9.2's stages 1–3 (invalid lines skipped and counted, an advisory CRITICAL kept CRITICAL,
+defects and advice merged apart by identity with every source label) into
+`merged.jsonl` and writes `informational.md` for the PR body. Missing or unusable
+output exits 3 with `REVIEW_COVERAGE_INCOMPLETE`
+([troubleshooting.md](troubleshooting.md#review-coverage-incomplete)). Selection, depth,
+the floor and the transitions are unchanged: only what a reviewer reads and what
+returns to the parent changed.
