From a5f0e9fe5236eecda82815c4e2b8916a2b46da04 Mon Sep 17 00:00:00 2001 From: dmitrii-f-t27 Date: Sat, 17 Oct 2026 11:37:59 -0300 Subject: [PATCH] spec(port): port specs/port/trios/crates/trios-claude/src/process.t27 (Closes #6384) Port gHashTag/trios:crates/trios-claude/src/process.rs (at 8b229e9e9489ee, 130 lines) as specs/port/trios/crates/ trios-claude/src/process.t27 - Roadmap Stage 6, goal #4548, target t27c gen-rust. The Claude CLI process driver's decisions are ported as pure functions and tested (7 tests, 7 pass, 0 vacuous, 33 runtime asserts, 100% function coverage): the childless start carrying only the config, the stdout/stderr/exit event triple, the create-only-when-missing directory rule, both invocations' exact argument table (claude --print --model --output-format json, the one-shot prompt appending as the final argument), the both-streams piping with the receiver-dropped break, the prompt verdict (trimmed stdout on success, the process-failed error carrying stderr otherwise), the kill that clears the held child, the running/status mapping (held = Running, none = Idle), and the Drop start-kill of only a held child - the last-resort cleanup. The process spawns, the stream pumps and the directory creation are the callers' plumbing. Verified: parse OK, spec-status IMPLEMENTED, typecheck 0 errors, coverage 17/17, test-report 7/7 pass, 0 BLOCKED, gen 159 lines with 0 'not yet implemented', boundary exactly this one file, dupe_scan: all 10 introduced names unique across 2042 specs AND the ProcessState struct verified absent from the corpus type set by grep before the commit, bare body scan adds no duplicate group (752/221 unchanged).
