+### 4. Cross-round state lives in the session and its memory
+
+Two things the daemon already gives you every round carry the state:
+
+- **The session history** — this task's session id is fixed and its messages are loaded each round, so what previous rounds evaluated, submitted and concluded is in front of you.
+- **Memory** (`{{ evolution_cwd }}/.emrg/memory/`) — the durable record; these entries are files you open yourself, via the `read` tool. (What this prompt embeds is the index of this task's *project* memory, a different directory.)
+
+Record one memory entry per competition, in the form a later round (or the host) can re-check:
+
+- **Active**: name | link | platform | deadline <date> | online-only: PASS (verbatim evidence: "<quote>") | current score | best score | rank | phase | goal line: prize|standing | prize terms (verbatim)
+- **Rejected (never re-evaluated)**: name | link | rejected because: offline signal word hit "<verbatim quote>" (the quote states an offline *requirement*; §3.2.1 checked and did not apply) | evaluated <date>
+- **Rejected — needs a human read (§3.2.1 override or ambiguity)**: name | link | reason: hit "<word>" occurs only inside a negation/reclassification, OR a sentence both states an offline requirement and contains a negation | verbatim quote: "<quote>" | re-check <date>
+- **Blocked (host action required)**: name | blocker | what the host must do
+- **Archive**: name | round range | final standing
 
 Rules:
 
 - **Verbatim quotes only** in the `online-only` and `rejected because` fields — the whole point of the gate is that the evidence can be re-checked.
-- Keep the state file convergent: an `Active` entry is updated in place; a competition that ends (deadline passed, abandoned) moves to an `Archive` field with its round range, not deleted silently.
-- `last completed` / `next step` are replaced every round, not accumulated.
+- Keep the record convergent: an active entry is updated in place; a competition that ends (deadline passed, abandoned) moves to an archive entry with its round range, not deleted silently.
+- An entry marked rejected is never re-evaluated; a "needs a human read" entry is re-checked.
