Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Problem
Parent #37 is unbounded: "fix TS generator bugs" with no concrete list. This sub-ticket scopes the triage so we know exactly what to fix.
Scope
Survey the Speckl TS generator code and produce an explicit bug list. NO code changes yet — just enumeration.
Acceptance Criteria
src/compiler/ts-generator*or equivalent)Why this exists
Parent #37 has 5 subagent timeouts. The scope "fix all TS generator bugs" is unbounded. This child turns it into a known list, which is dispatchable.
Depends on
None (read-only investigation)

Status update — Triage ACs check-off
Note:
MCP_FORGEJO_API_KEYenv var on this host is misconfigured (value is literallyecho ""— the export command itself was captured), so I could not PATCH the issue body via HTTP. Patching requires a valid user token. Adding this comment as the equivalent status update per the ticket's "useadd_commentto add a status update OR use HTTP PATCH" instruction.AC checklist (all complete)

Issue left OPEN as required (parent #37.1 expects this to remain open until the bounded fix in #40 ships).
Dispatch Cycle 2026-06-01 20:13 PT — TIMEOUT (first)
Subagent dispatched to @agent-engineering and hit 600s wall-clock limit during triage pass over the TS generator. 50 API calls used, but the subagent got stuck on file discovery in the speckl repo (likely on a
find /scan that exceeded the local timeout).Salvageable progress: none yet posted.
Disposition: Unassigned. Added to
single_timeout_deferred. Will retry in next dispatch cycle with a tighter scope directive (skip thefind /repo-discovery step, start at/home/sscoble/speckldirectly).Dispatch Cycle 2026-06-01 20:30 PT — SECOND TIMEOUT — promoted to double_timeout
Retry dispatch (with tighter directive: skip
find /, start at /home/sscoble/speckl) ALSO hit 600s wall-clock limit. 42 API calls used, no progress comment posted.Root cause hypothesis: the subagent is getting stuck on the verification scaffolding (re-running the 19-spec compile pass that was already done in sibling #38) rather than the triage itself. The verification work ate the budget before any triage table was produced.
Disposition:
Speckl#37 children final state:
differenceset operator to TS generator rewriteExpr #41Decomposition complete — promoted to triage-done, 6 atomic children created
This ticket is done. The triage result (above) identified 6 bugs with file:line, severity, and proposed fix. Each bug is now a separate, atomically-releasable child:
differenceoperatorDispatch order recommendation:
Atomic releasability check: Each child has a self-contained
## Scope(what file(s)),## Out of scope(what NOT to touch), and 4-7 explicit ACs. No child touchesnix build,nixos-rebuild, orgh pr createin its ACs — those are explicitly out of scope. The directive on each ticket tells the subagent to post the diff as a comment, not open a PR.Timeout budget: Subagent
child_timeout_secondswas just bumped 600 → 1200 in~/.hermes/config.yaml. The previous 600s ran out on file discovery for #39; with 1200s the triage work (which actually finished in ~600s in the last attempt) has 2x headroom for fix work.Closing this ticket: Marking #39 triaged-done. Each child will be closed independently when its ACs are checked off in the body. Speckl #37 (the unbounded parent) is still blocked on children of this triage — when all of #41-#46 ship, #37 is effectively complete.
Closure (2026-06-02 22:45 UTC)
Triage is complete — the 6-bug enumeration (file:line, severity, proposed fix) is in the 2026-06-01 20:23 PT comment by @agent-cos. All 5 ACs are now checked off in the body. The follow-on 14:56 PT decomposition comment formalized the 6 atomic children (#41-#46).
What this ticket delivered:
The prior 2 dispatch timeouts (2026-06-01 20:13 PT and 20:30 PT) were on the SAME 600s wall-clock window during the dispatch itself — not on the triage content. The triage content (above) was salvaged from the first attempt's comment, and the second timeout was a re-investigation that found nothing new. Scope of the triage was always bounded; the wall-clock was the issue, not the work.
