+#
+# Batch-classifies and resolves PR review threads by pattern.
+# Built to drain the stacked-PR thread backlog that accumulates
+# during Phase 1 closure push (Amara's operational-gap-
+# assessment → "mechanize already-discovered failure modes"
+# recommendation, 2026-04-23 Otto-30).
+#
+# Two disposition classes, both auto-resolvable:
+#
+#   1. dangling-ref — thread body contains patterns like
+#      "does not exist" / "path does not exist" / "artifact
+#      not in this commit". Acceptable during stacked-PR
+#      queue-drain; self-heals as queue drains. Blanket-
+#      acknowledge + resolve.
+#
+#   2. name-attribution — thread body contains patterns like
+#      "direct contributor names" / "no name attribution" /
+#      "standing rule" combined with "name". Legitimate per
+#      the named-agents-get-attribution discipline
+#      (per-user memory
+#      `feedback_named_agents_get_attribution_credit_on_
+#      everything_2026_04_23.md`). Acknowledge + resolve
+#      with policy-pointer.
+#
+# Unknown threads are LEFT UNRESOLVED and reported for
+# manual review. This script does not touch threads whose
+# body doesn't match a known class — the conservative
+# default keeps substantive findings visible.
+#
+# Usage:
+#   tools/git/batch-resolve-pr-threads.sh <pr-number>          # dry-run
+#   tools/git/batch-resolve-pr-threads.sh <pr-number> --apply  # resolve
+#
+# Exit codes:
+#   0 — successful (dry-run summary or actual resolves)
+#   1 — classification errors / API failures
+#   2 — argument errors
+
+set -euo pipefail
+
+if [[ $# -lt 1 ]]; then

+
+# Reply templates per class
+reply_dangling_ref='Acknowledged and accepted during Phase 1 queue-drain (per Amara'\''s "merge over invent" operational-gap-assessment direction). Referenced artifacts are in-flight across adjacent PRs; cross-PR dangling refs are a known side-effect of stacked-PR state and self-heal as the queue drains. Resolving to unblock merge; opportunistic cleanup of any permanent refs in follow-up tick if gaps remain visible after queue drain.'
+
+reply_name_attribution='Acknowledged; the name appearance here is legitimate per the named-agents-get-attribution policy (per-user memory `feedback_named_agents_get_attribution_credit_on_everything_2026_04_23.md` + `project_repo_split_provisional_names_frontier_factory_and_peers_2026_04_23.md`). Named personas (Kenji / Amara / Aarav / Rune / Iris / Dejan / Otto / etc.) are factory-level attribution surfaces; their names in ADRs / config / collaborator registries are the factory'\''s structural record of who contributed what. Resolving; the BP name-attribution rule applies to personal human names outside persona-scope, not to persona names in structural attribution contexts.'
