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?
Status: CRITICAL — Speckl compiler regression caused by CoS premature closure
This ticket re-files the work that was completed and verified in two prior dispatch cycles (sscoble/speckl#47 closed 2026-06-03 03:47 UTC; sscoble/speckl#49 closed 2026-06-03 03:01 UTC) but was never committed to git. The working tree changes were lost across 5

Scope (single coherent re-dispatch)
Part A — B2.1 constraint forwarding
In
compiler/src/generators/typescript-state-machine.ts, replace thereturn true;stub at lines 263-279 with a real boolean expression that callsrewriteExpr(c.expr, ...)and returns the result. The full change was previously verified at ~35 lines added, 9 removed.Part B — #49 multi-line input/output parser
In
compiler/src/parser.ts, extendparseMemberBlockto recognizeinput: { ... }andoutput: { ... }multi-line blocks and produce structured AST nodes (withfields: [{ name, typeExpr }]).Part C — Verification (must pass with 0 errors)
After Parts A+B: should produce 6 errors (per #50's known error set). After Part D (sibling #50 fixes): should produce 0 errors.

The CoS protocol must be amended: before HTTP PATCH close of any ticket with a code-fix dispatch, the CoS MUST commit the working tree on the assigned branch. The current protocol's "close after AC verification" step is incomplete when verification happens in the subagent's working tree rather than in committed code. This is the cause of:
decomposed_parents: 3housekeeping close pattern that closes parents whose children carry the work — needs the children to actually have the work committed before the parent can be safely closedBranch

Verification results
npx tscin compiler/: ✅ cleantsc --noEmiton emitted TS: 4 errors (TS2304 'Cannot find name' foruserId,patientWeight,limiter,maxRetries)Error-count deviation from spec (4 vs 6)
The spec predicted 6 errors per speckl#50's known residual set. We observed 4 — but a different shape:
The 4 observed errors are exactly speckl#50's issue #1 ("Input/output fields not declared as class properties") surfacing once the constraint forwarding is wired through — the new errors fire because the class doesn't declare input fields as
this.<field>, so the rewrittenreturn (userId !== "");references a bare identifier that TS cannot resolve.This is functionally correct for #51's scope (B2.1 forwarding + parser fix are both done). The 4 errors are out-of-scope for this ticket and explicitly carried in speckl#50 as a follow-up.

The CoS protocol gap from the prior cycle (working-tree verification without commit → lost work) is now closed: this dispatch committed the working tree to the branch before close. The CoS verified the commit SHA via
