+- **Gitea milestone-name issue filter silently NO-OPS on names with special chars (2026-07-17,
+  #77 selection)**: `GET /issues?milestones=<name>` returns the WHOLE open-issue list — not a
+  filtered set — when the milestone title contains `:` or `+` (e.g. `Scheduling: refactor +
+  distribution`), because the raw name doesn't round-trip through Gitea's filter. A selector that
+  trusts that response will mis-tier issues (it made #72 look like a milestone-10 member when it's
+  unmilestoned, and hid #77's true sibling set). **Robust recipe: fetch all open issues once and
+  filter LOCALLY on each issue's `.milestone.title`** (`?state=open&type=issues&limit=50`, then
+  `[i for i in issues if (i['milestone'] or {}).get('title')==NAME]`) — do not rely on the
+  server-side `milestones=` name filter. If a count looks suspiciously like "all open issues," that
+  filter silently failed; re-derive membership locally. (Dependencies API is fine: `POST
+  /issues/{n}/dependencies` with `{"owner","repo","index"}` sets blocked-by; the bare `{index}`
+  form 201s but may not attach — verify with the GET.)
 - **Codex cheap-worker launch (tested 2026-07-14)**: the native `spawn_agent` interface currently
   has no model/effort selector, so it provides parallelism but not cost savings. For bounded,
   tool-bearing selector/recon work, launch a separate worker with
