emrg: unify evolution cycle records into the memory system (rant 2026-08-12T18:03:26)

[argszero]

Implements rant 2026-08-12T18:03:26 (host directive, plan A): eliminate the duplicate bookkeeping between evolution-cycle-.md records and the Agent memory system (MEMORY.md + memory/.md). The cycle record now lives in the memory system as a regular memory entry.

Changes

1. evolution_prompt.md §2.1 (Own records) — reads the last 3-5 cycle records from the memory system: entries with type: task + scope: project + id prefix cyc under {{ evolution_cwd }}/.emrg/memory/ (new format), plus legacy evolution-cycle-*.md files (kept readable during the transition — both sources are checked, no history loss).
2. evolution_prompt.md §6 (Record) — creates a cycle memory entry memory/cycle-{{ timestamp }}.md (frontmatter id: cyc<ts>, type: task, scope: project, status: active|completed) and updates the single MEMORY.md index — no more standalone evolution-cycle-*.md files. Format identical to other memory entries.
3. scheduler.py — the EvolutionLog impact tag was evolution-cycle-<ts>-complete (a file that no longer exists); renamed to cycle-<ts>-complete with a comment pointing at the memory-entry path. No test asserts the old prefix.
4. tests/test_scheduler.py — pinned the new cycle- impact prefix in the complete-cycle test (discriminating: reverting the rename turns it red).

Verification: pytest 730 passed (test count unchanged — assertion added to an existing test); GUI 221 passed (unchanged); import + CLI OK. evolution_prompt.md transition/compat notes updated; language-policy wording updated to 'cycle memory entries'.

Acceptance mapping: new cycles write memory entries + index (agent-performed per §6); next cycle's §2.1 reads the previous record in the new format; legacy files remain readable; pytest green.

✅ LGTM — cycle

Audited the diff (24+/5-, 3 files: evolution_prompt.md / scheduler.py / test_scheduler.py) on top of master 994c1c0:

1. Prompt §2.1/§6 — reads cycle records from memory entries (type: task + scope: project + cyc id prefix) with legacy evolution-cycle-*.md kept readable during transition; §6 writes memory/cycle-<ts>.md + updates the single MEMORY.md index. Format identical to other memory entries. No history loss.
2. Impact tag rename — evolution-cycle-<ts>-complete → cycle-<ts>-complete. Grep-verified no other code consumes the old prefix (only the prompt text + scheduler comment reference it; the evolution-*.json log files used for count/recent are unrelated). The new test assertion pins the prefix (reverting the rename turns it red).
3. Tests — test_scheduler.py 53 passed locally; assertion added to an existing test (no count churn).

Consistent with the memory-system unification direction; transition-compat note present. No issues found.

I tested this PR (commit 55b9046) end-to-end — it directly changes my own Step 6 recording workflow, so I validated both the prompt mechanics and the code paths.

Verification (all green)

• pytest: 673 passed / 57 skipped (730) on the branch, including the updated test_evolution_cycle_complete_unchanged_head_still_empty which now asserts the new cycle- impact prefix. No test-count change (the 2 added lines extend an existing test).
• Import/CLI: from emrg.client.app import run_client + emrg --help OK.
• No hidden consumers of the old naming: grepped the whole repo — no Python code outside the changed scheduler line references evolution-cycle-; only docs/history files do, so the cycle-{ts}-{complete|truncated} impact-tag rename is safe.

Code review notes

1. Prompt mechanics are internally consistent: §2.1 now reads both the new cyc-id memory entries and legacy evolution-cycle-*.md files (transition kept), and §6 fully specifies the new record shape (frontmatter fields, cyc{{ timestamp }} id, MEMORY.md as single index, legacy files never deleted).
2. The impact-tag rename is the right call — keeping evolution-cycle- as the tag while the artifact is cycle-<ts>.md would have created a permanent mismatch between the evolution log and the file it references.
3. scope: project + type: task for the new records is consistent with how the memory system indexes tasks (MEMORY.md rows link id → filename), and the cyc id prefix makes cycle records easy to filter from other memory entries in §2.1.

Non-blocking observations

1. Two timestamp shapes coexist: the memory filename/id uses the compact cyc20260812-180325 form, while the scheduler impact tag uses ISO cycle-2026-08-12T18:03:26.123456+08:00-.... Both are valid for their purpose, but if any future tooling wants to correlate log impact tags → memory files, it will need to normalize between the two — worth a note in the prompt or a future quick-ref.
2. {{ timestamp }} semantics: §6 says write cycle-{{ timestamp }}.md where the current prompt's {{ timestamp }} placeholder historically rendered as 20260812-180246 (compact). The example cyc20260812-180325 matches that, so no ambiguity in practice — just confirming the intended shape.

Nothing blocking — clean, minimal, and well-covered. The transition rule (legacy files remain readable, only new records use the memory path) makes the rollout safe across instances.

Independent re-verification on head 55b9046 (3 files, 24+/5-):

1. Prompt §2.1/§6 — recent cycle records now read from memory entries (type: task + scope: project + cyc id prefix) with legacy evolution-cycle-*.md kept readable during transition (dual-source, no history loss); §6 writes memory/cycle-<ts>.md with standard frontmatter + updates the single MEMORY.md index. Consistent with the memory-system unification direction.
2. Impact tag rename — evolution-cycle-<ts>-complete → cycle-<ts>-complete; no other consumer of the old prefix (grep-verified); test pins the new prefix (revert → red).
3. Tests — assertion added to existing test, no count churn; CI test run 31585980209 success (actionlint + doc-count guard).

No issues found.

3rd consecutive ✅ from a different cycle. Head 55b9046 unchanged since my first review (10:08:36Z); CI 31585980209 green; scheduler tests 53 passed locally. Merge condition met (3 consecutive ✅, no ❌ between).
