TL;DR: gstack-memory-ingest --bulk fails on every page with Unknown command: put_page. gstack 1.26.0.0 invokes gbrain put_page (the internal operation name); gbrain v0.18.2 only registers the user-facing alias gbrain put from cliHints.name.

Repro

Fresh install on Linux:

• gstack v1.26.0.0 (commit bf65487 on garrytan/gstack:main)
• gbrain v0.18.2 (commit 08b3698 on garrytan/gbrain:main)
• PGLite engine, 75 transcripts on disk

$ bun ~/.claude/skills/gstack/bin/gstack-memory-ingest.ts --probe
Total files in window: 75
New (never ingested):  75
Estimate: ~1 min for full --bulk pass.

Root cause

bin/gstack-memory-ingest.ts:762-784 builds the args:

const args = [
  "put_page",
  "--slug", page.slug,
  "--title", page.title,
  "--type", page.type,
  "--tags", page.tags.join(","),
];
execFileSync("gbrain", args, { input: page.body, ... });

But gbrain v0.18.2 src/cli.ts:13-18 only registers user-facing CLI commands from cliHints.name:

for (const op of operations) {
  const name = op.cliHints?.name;
  if (name && !op.cliHints?.hidden) {
    cliOps.set(name, op);
  }
}

In src/core/operations.ts:243-244, the operation is name: 'put_page' with cliHints: { name: 'put', positional: ['slug'] }. So gbrain put is registered; gbrain put_page is not.

Same mismatch likely affects bin/gstack-brain-context-load.ts (uses gbrain list_pages per the file's own comment at line 10 — gbrain CLI exposes gbrain list).

Suggested fix

Either:

1. gstack side (faster): swap put_page → put and list_pages → list, adjust args to match the user-facing CLI shape (gbrain put <slug> reads body from stdin, supports --title/--type/--tags via flags).
2. gbrain side: register operation name as a CLI alias alongside cliHints.name so internal names also work as commands. Bigger surface change.

Workaround

gstack-config set transcript_ingest_mode off so preambles stop retrying. The rest of /setup-gbrain (engine init, code import, MCP register, brain-sync wireup, smoke test) works fine — just the V1 transcript/memory ingest pipeline is dead until either side ships the alias.
