 Refactor Phases 7–9's Discord code behind the declared-capability registry (§8.2) and prove it by
 rendering the admin UI from the declaration rather than from a hardcoded "Discord" assumption. Last on
 purpose: extracting a capability surface from one working implementation is honest; designing it before
 one exists is speculation.
 
+**Why cancelling it costs little.** The same argument that put it last is the argument for not doing it
+yet: with exactly one integration built, the refactor would extract a capability surface from a single
+implementation and have nothing to check the extraction against. §8.2's Matrix column is research, not
+a second implementation, and a registry whose only consumer is the thing it was extracted from is a
+layer of indirection that has not yet been paid for. The work is cheaper *and* better-informed the day
+a second platform exists, because that platform is what proves which of the five capabilities the
+seam actually needs.
+
+**What it leaves behind, stated so nobody has to re-derive it.** Phases 7–9 name Discord directly —
+in the bridge config (`team_discord_config`), the voice provisioner, the slash-command dispatcher and
+their admin panels. That is not a defect and no code is placed differently in anticipation of a layer
+that may never come. Two decisions were made *for* this phase, and both stand on their own:
+the notification bridge and the voice panel live under **Admin → Teams** rather than inside the
+Discord Bot panel (§7.2, §7.3), because where an operator goes to find them should not depend on which
+platform fills them; and core's calls are already phrased as questions about eligibility — *these user
+ids are eligible for Team 3* — rather than as instructions about overwrites. A second integration
+would be a new phase against that surface, not a rescue of this one.
