 | 6 | nit | Ornith (task 10) | The row gives one gate run and a first pass; its notes say the first run failed on six clippy warnings. | Noted here |
 | 7 | medium | the run, not the code | Task 10 ran past the 90-minute limit, and `RESUME` resumes only a session that ended by itself, so the run stopped; the owner resumed it by hand. Global OpenCode plugins loaded into every session: one rewrote the system prompt every fourth request, forcing full re-reads (tasks 01 to 10: prompt reads of 10,000 tokens or more took 76 of 111 minutes of prompt processing). | Plugins removed (owner, 2026-09-27); tip T48; `run-plan.sh` to pass `--pure` and resume after the limit |
 | 8 | low | tests (M4b) | `brokerd`'s `a_torn_tail_is_recovered_and_it_serves` failed once under full load (task 07's first gate) and passed alone. | Open |
+| 10 | high (for the device) | plan (task 08; the reference too) | The self-test asked `/tokenize` about each tag and each neutralised form, 66 requests, one connection each, and `inferproxy` allows a burst of ten (M2a spec): on straylight the ninth tag request was refused and `loopd` would not start. Every given test talks to a fake server directly, with no `inferproxy`. | Review: two requests, all the tags at once, then all the forms (spec 8, runbook, `selftest_tags.rs`); tip T49 |
 | 9 | low | tests (M2b) | `loopd`'s `serve_refuses_to_start_when_the_self_test_fails` and `a_failed_self_test_names_its_entry` wait on the process with no deadline; a `serve` that skipped the self-test would hang the gate (found while writing task 08). | Open |
