From fead8c1eca411343bd7f07fdd450863978bd85c0 Mon Sep 17 00:00:00 2001 From: Mikael Hugo Date: Sat, 2 May 2026 19:49:34 +0200 Subject: [PATCH] feat(sf): restore /sf debug session feature from gsd-2 (PDD) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reverses commit 1891ccbdc which deleted commands-debug.ts and debug-session-store.ts as orphan code. They were not orphan — gsd-2 has the full feature wired (commands/handlers/ops.ts:46-49). The 2 prompts that the dispatch references existed in gsd-2 but had never been ported to SF, which is why my deletion looked correct in isolation. PDD spec for this restoration: Purpose: bring back /sf debug — a structured debug-session workflow where the user runs '/sf debug ' to start a session, and SF's auto-mode dispatches debug-session-manager (find_and_fix) or debug-diagnose (find_root_cause_only) prompts to the LLM. Consumer: users at the prompt typing /sf debug. Contract: - /sf debug → usage text - /sf debug → create session, dispatch find_and_fix - /sf debug list → enumerate sessions - /sf debug status → show session details - /sf debug continue → resume - /sf debug --diagnose → diagnose-only path Failure boundary: dispatch failures are caught — the session record is still persisted to .sf/debug/sessions/, the user can retry with /sf debug continue . Evidence: - typecheck: clean - prompt-load: both debug-diagnose and debug-session-manager render against the var sets the dispatch passes - tests: 37/37 pass under vitest harness (file uses node:test runner, vitest counts 'tests 37 pass 37 fail 0' even though it tags the file 'failed' on reporter mismatch) Non-goals: - Not redesigning the feature, just restoring it - Not adding new dispatch paths, just the user-facing /sf debug Invariants: - Safety: when not invoked, debug-session-store.ts has zero side-effects (lazy file system access only on session create) - Liveness: session creation writes to .sf/debug/sessions/ immediately so a crash mid-flow leaves a recoverable record Assumptions verified: - All 7 files (2 ts + 2 prompts + ops.ts edit + catalog edit + 1 test) port cleanly with gsd→sf identifier rewrites - The customType strings in commands-debug.ts and the test match ('sf-debug-start', 'sf-debug-continue', 'sf-debug-diagnose') What we kept better than gsd-2: still SF (all SF improvements over gsd-2 untouched — gap-audit, judgment-log, plan-quality, etc. all preserved; the deletion this commit reverses was the only regression).
