From 2b8c95986c34e3f4127b7608db975509a33cf1b3 Mon Sep 17 00:00:00 2001 From: CCC Date: Sat, 26 Sep 2026 08:26:15 +0800 Subject: [PATCH] quilt_emit: vessel lifecycle events -> quilt 5-opcode WAL (first quilt-native fleet agent) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit git-agent's vessel already emits structured lifecycle events (session start, worklog, task outcomes, career promotions, fences, skills, snapshots, heartbeats, session end) but nothing turned them into durable, verifiable records. This adds the missing translation + validation layer: - git_agent/quilt_emit.py — QuiltEmitter: validate -> map -> append to an fnv1a hash-chained JSONL WAL (default ~/.git-agent/quilt.jsonl); replay() reconstructs reducer state from the WAL alone; verify() catches tampering (hash recompute), truncation (chain linkage + seq continuity), and replay divergence. Invalid events raise QuiltValidationError with the precise missing/invalid field — never silently dropped, never crash the ingest loop. Duplicate event_id delivery is idempotent (at-least-once ingest -> exactly-once WAL). - git_agent/schemas/event.schema.json — canonical JSON Schema, shipped with the producer per fleet doctrine (schemas belong with the producer). - tests/fixtures/*.json — REAL event payloads captured from a live VesselManager via tests/_capture_fixtures.py (kept for regeneration). - tests/test_quilt_emit.py — 25 behavioral checks, FAIL-first. Opcode mapping: session_start->BIND(identity), worklog->LINK, task_completion /promotion/fence->EFFECT, skill->BIND(skills), snapshot->VIEW, heartbeat->TICK, session_end->FORGET(archived). Suite: 259 passed (234 prior + 25 new), 4.14s. --- src/git_agent/quilt_emit.py | 245 ++++++++++++++++++++++++ src/git_agent/schemas/event.schema.json | 101 ++++++++++ tests/_capture_fixtures.py | 88 +++++++++ tests/fixtures/fence.json | 6 + tests/fixtures/heartbeat.json | 5 + tests/fixtures/promotion.json | 7 + tests/fixtures/session_end.json | 6 + tests/fixtures/session_start.json | 11 ++ tests/fixtures/skill.json | 6 + tests/fixtures/snapshot.json | 9 + tests/fixtures/task_completion.json | 6 + tests/fixtures/worklog.json | 9 + tests/test_quilt_emit.py | 195 +++++++++++++++++++ 13 files changed, 694 insertions(+) create mode 100644 src/git_agent/quilt_emit.py create mode 100644 src/git_agent/schemas/event.schema.json create mode 100644 tests/_capture_fixtures.py create mode 100644 tests/fixtures/fence.json create mode 100644 tests/fixtures/heartbeat.json create mode 100644 tests/fixtures/promotion.json create mode 100644 tests/fixtures/session_end.json create mode 100644 tests/fixtures/session_start.json create mode 100644 tests/fixtures/skill.json create mode 100644 tests/fixtures/snapshot.json create mode 100644 tests/fixtures/task_completion.json create mode 100644 tests/fixtures/worklog.json create mode 100644 tests/test_quilt_emit.py diff --git a/src/git_agent/quilt_emit.py b/src/git_agent/quilt_emit.py new file mode 100644 index 0000000..7e7e270 --- /dev/null +++ b/src/git_agent/quilt_emit.py @@ -0,0 +1,245 @@ +""" +Vessel-Quilt emitter — git-agent's lifecycle events as quilt 5-opcode WAL records. + +The fleet's quilt kernel speaks five opcodes (BIND / LINK / EFFECT / VIEW / TICK, +plus FORGET). git-agent's vessel already produces structured lifecycle events +(session start, worklog entries, task outcomes, career promotions, fences, +skills, snapshots, heartbeats, session end) — this module is the translation +and validation layer that makes git-agent the first quilt-native fleet agent. + +Every ingested event is: + 1. validated against the event schema (enforced here in stdlib code; the + canonical JSON Schema lives beside the producer at + ``git_agent/schemas/event.schema.json`` for external consumers), + 2. mapped to exactly one quilt opcode line, + 3. appended to a fnv1a hash-chained JSONL WAL (default ``~/.git-agent/quilt.jsonl``), + 4. folded into a reducer state that ``replay()`` can reconstruct from the WAL alone. + +Guarantees: invalid events raise ``QuiltValidationError`` (never silently +dropped, never crash the ingest loop); duplicate ``event_id`` deliveries are +idempotent (at-least-once ingest → exactly-once WAL). +""" + +from __future__ import annotations + +import datetime +import json +import re +from pathlib import Path +from typing import Any, Dict, List, Optional + +SCHEMA_PATH = Path(__file__).parent / "schemas" / "event.schema.json" + +DEFAULT_WAL = Path.home() / ".git-agent" / "quilt.jsonl" + +EVENT_TYPES = ( + "session_start", "worklog", "task_completion", "promotion", + "fence", "skill", "snapshot", "heartbeat", "session_end", +) + +# per-type required fields beyond the universal (event_id, type, timestamp) +REQUIRED: Dict[str, tuple] = { + "session_start": ("name", "designation", "version"), + "worklog": ("action", "target", "summary", "outcome"), + "task_completion": ("success",), + "promotion": ("from_stage", "to_stage"), + "fence": ("fence_name",), + "skill": ("skill",), + "snapshot": ("stage",), + "heartbeat": (), + "session_end": (), +} + +OUTCOMES = ("success", "failure", "partial") +_TS_RE = re.compile(r"^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}") + + +class QuiltValidationError(ValueError): + """Raised when an event fails schema validation.
