GustavoandClaude Sonnet 5 ea105d525c fix(v2): three real bugs found by an actual end-to-end run against production GLPI data 
Ran the deployed workflow for real (temporary webhook trigger, briefly
activated, immediately deactivated and removed after each attempt) against
the real GLPI MySQL database and a real OpenAI credential. Found and fixed:

1. $env access is blocked on this n8n instance (N8N_BLOCK_ENV_ACCESS_IN_NODE).
   parseConfig($env) threw "access to env vars denied" on the very first
   Code node. Config now comes from the "Config - Coordenador GLPI v2" Set
   node instead (same pattern the V1 workflow already used) -- expanded
   that node with all 13 tunable parameters, and pointed the 3 affected
   node drivers (build-sql-candidatos, decide-needs-ai, select-top10) at
   it instead of $env.

2. Data Table "upsert" operation requires both `columns` (values) and a
   separate `filters` (match condition) -- I had only set columns with
   matchingColumns, which isn't enough; n8n refused to activate the
   workflow ("Missing or invalid required parameters: filters"). Added
   filters.conditions matching on ticket_id to both memory-writing Data
   Table nodes.

3. Real architecture bug: "Data Table - Buscar Memoria" sat inline in the
   41-candidate chain (Mesclar Contexto -> Buscar Memoria -> Decidir
   Necessidade de IA). A bulk "get all rows" Data Table node run with 41
   input items produced 41 identical fetches and its OWN output (the empty
   memory table on a first run) replaced the 41 candidates entirely --
   "Decidir Necessidade de IA" received 0 items and the whole main branch
   silently skipped. Moved the memory fetch to a parallel branch off
   Config (fires once) and added a real Merge node ("Merge - Aguardar
   Memoria") to guarantee both the candidates and the memory rows have
   executed before "Decidir Necessidade de IA" runs -- same synchronization
   pattern already used for context and for the shadow comparison.

Also fixed a cosmetic bug found in the real message output: buildTopMessage
produced a quadruple newline between the header and the first ticket block
([header, '', ...blocks].join('\n\n') double-counts the blank line already
inserted by the '\n\n' join). Added a regression test.

Verified with a real execution (id 13599, 24/08/2026 19:25 UTC) against the
live GLPI database: 41 real candidates, 30 sent to OpenAI (capped), 11
fallback-capped, memory table populated with 41 real rows including
genuine WAITING_VENDOR/WAITING_REQUESTER classifications with real
blocker_type/waiting_for fields extracted from real ticket task content,
and a real shadow_runs row comparing Legacy x V2 (4 tickets removed by V2:
2 for INSUFFICIENT_CONTEXT, 1 WAITING_REQUESTER, 1 WAITING_VENDOR; 4 added).
