v0.9.0 Release Plan (rev 2) — Freeze Wed Aug 19

v0.9.0 release plan (rev 2)— plan PR #2096. Freeze Wed Aug 19. Headline: Workspace ships, skills library ships safely, schedules work again.

Now — by Wed Aug 12 (dev is broken)

•PR #2095 — schedule enable/disable/trigger 422 regression (#2094, P0). CI green; needs a reviewer today.
•Enterprise pin bump → bce1175 (ent#356). Verify Alembic heads merge cleanly first — #2068 is exactly this failure mode (two heads → entitled instances silently degrade to OSS-only).
•Compose passthrough for TRINITY_DEFAULT_SKILL_SOURCE(_REF) (ent#237) — add to the backend's explicit env list, same pattern as TRINITY_DEFAULT_SYSTEM_MANIFEST.
•PR #2024 — approved + green, just merge it.

•Security:ent#346 (P0, in progress) · ent#292 (P0 — PAT leak in sweeper logs, added; was missing from rev 1) · written ship/block decision on the ent#297/293/334 agent-key-admin cluster, recorded on #2096.
•Workspace core(all in progress): PR #2083 rename + one-click (ent#357 — green, needs review) · ent#375 sliding session renewal · ent#286 streaming · ent#362 workspace user as room participant (P1, added; was missing).
•In-flight bugs:ent#218 + ent#220 rooms edges · #1976 and #2076 — fix red CI, then merge · #2079 docs (green, needs review).
