The rehearsal's inbound-level totals never moved: the agent
reports sing-box tags (inbound-<port>) while the master's agent
traffic handler matches inbound rows by their panel tag — which
the B1 model renamed to the n<node>-in- scheme, so the lookup
silently matched nothing (per-user totals, keyed by email, were
unaffected; production on V1 keeps the old tag form and is not
hit until the V2 migration itself).
The converter now takes the row's panel tag as the fragment tag
(migrator passes it through), making one identity serve the DB
row, the generated config, core stats and traffic reports. Bare
fixtures without a panel tag keep the historical form.
New stored model (legacy columns untouched, read paths unchanged
until B2):
- inbounds.singbox_config (converted sing-box inbound/endpoint
fragment JSON; empty = blocked or external-runtime) and
inbounds.singbox_preserved (unmapped items verbatim + panel-side
material + notes)
- agent_nodes.singbox_outbounds / singbox_routing_rules
Converter (internal/singbox, pure functions, ITEM6-CONVERSION-SPEC):
all panel protocols mapped; unmapped constructs are preserved and
registered, never dropped. B0 golden fixtures: 26/26 semantic match
(fragment + unmapped concept/pending sets + disposition).
One-shot migrator (internal/database, InitDB hook after initModels):
marker-gated and idempotent; SQLite file backup before any write
(failure refuses migration/startup); stats switches migrate out of
the template BEFORE the xrayTemplateConfig row is discarded
(SCOPE 4.3.1 order); identity layer is the only client truth with
spec 7-1 mirror reconciliation (adopt/fill/conflict all reported);
fallbacks merged from table + embedded settings, deduped; agent
overrides converted with per-entry issues; everything in one
transaction, marker written last; JSON report written next to the
DB. Malformed rows/templates are hard failures (rollback, old DB
untouched).
settings.trafficStatsSwitches added with factory defaults
(inbound on, outbound off) in defaultValueMap.
Validation: synthetic agent-era DB (mirror drift, fallbacks, xhttp,
agent geo rule, non-default stats) converts as specified; old
production backup (25 inbounds) migrates with credentials, Reality
pbk derivation, traffic counters and reset cycles byte-identical;
idempotent re-run is a no-op; touched packages show zero new test
failures vs the 9-red baseline.
