Agent Plugins 0.18.0

A second tutorial continues the first: the ESS tutorial's library gets an AEP plan, four critics
review it, and the first story is built in a reviewed wave. The skills are verified against aep
0.64.0 and ess 0.39.0, and a new report and skill keep this repository in step with the releases
it depends on.

• New page: Your first governed plan, recorded with
  aep 0.64.0 and ess 0.39.0: adopt an aep.project/5 store, model a new state in ESS before any
  story is written (17 → 55 scenarios), six stories, four critic verdicts, a wave proposal, and one
  story implemented, attacked by the adversary and merged. The aep-tutorial trial has a fresh
  agent follow it.
• agentplugins-check upstream reports what moved in every repository this one depends on: the
  releases its plugins drive with their changelog sections, the beyond10x/* workflow pins, and
  the issues its text cites. .agents/skills/following-upstream is the loop that acts on it.
• agentplugins-check refuses a b10x.docs.yaml link that names no page. One such link
  (plugins/beyond10x/, renamed in 0.14.0) failed every organization website publication from
  2026-09-24 to 2026-09-28.
• verified.json pins aep 0.64.0 and ess 0.39.0. ess:retrofitting and syntax.md: a read by
  identity is the unfiltered view; filter: id == param.id leaves every outcome it observes
  unsynthesized (beyond10x/ess#193). ess:hardening covers the concurrent explorer and
  ess verify conform check-history.
• aep:planning checks each critic's verdict line before recording it; the decomposer relates each
  story to the epic's objective, which development.standard requires before a story is accepted.
• Eval recording moved to metaharness aep drive eval run with aep 0.64.0; it is blocked until
  metaharness links a current aep (beyond10x/metaharness#10). The four plan-critic cases have a
  working tree, fixtures/library-reservations-drafted.
• task trial:sandbox can recreate a sandbox that ran aep.
