Append-only
Events are immutable entries with parents, timestamps, and actors. Trails never rewrite history; they only extend it.
Tongbuku 同步库 stores append-only trails of events you can replay, analyze, and reuse as templates. It keeps sync verifiable, views model-ready, and every turn aligned with ChatCard identity and EarthCloud meaning.
Trusted by Glyphd Labs for EarthCloud meaning trails, Buoychong worlds, and future VibeCherry/Funwae experiments.

What is a trail?
A trail is the ground truth history for a document, room, or workflow. Append-only events capture every turn, transformation, and model output. Trails are verifiable via hashes, merge safely across devices, and stay linked to the semantic layers above them.
Events are immutable entries with parents, timestamps, and actors. Trails never rewrite history; they only extend it.
Each event carries tags, channel hints, and stack metadata so you can filter by room, persona, tool, or tenant without bespoke joins.
Views and summaries stay aligned with the underlying trail so EarthCloud, Buoychong, and your own agents can ingest clean context.
Core concepts
Append-only sequence of events for a conversation, workflow, or document. Branches reconcile later through Merkle heads.
Immutable JSON envelope describing one action or observation. Carries actors, payload, parents, and tags for routing.
Derived representation of one or more trails—summaries, snapshots, or indexes that stay ready for models and audits.
Use cases
Capture every human and agent turn in one trail so support leads, compliance teams, and models can replay the same story.
Link design reviews, approvals, and prototype demos as events in a trail so directors can inspect decisions and fork new runs.
Query trails to study behavior over time, tag moments of interest, and hand clean projections to data scientists.
Export views from curated trails as labeled corpora for fine-tuning and eval, with traceable provenance for every example.
Data model & spec teaser
Events, trails, and views are spelled out in the spec. JSON stays compact but expressive: actors, tags, payloads, and merkle metadata fit into a single envelope so you can ship quickly without inventing another event format.

}Example flows
Clients append JSON events via `/v1/events/append` with dedupe + actor metadata.
Devices and services exchange Merkle heads to request only the events they are missing.
Tongbuku 同步库 maintains snapshots, indexes, and GlyphIR-aligned summaries tuned for AI workloads.
Views stream into EarthCloud, ChatCard, or your own pipelines as ready-made context.
Status & stack
ChatCard anchors who is acting, EarthCloud captures what each turn means, and Tongbuku 同步库 records when and where it happened as a reusable trail. Glyphd Labs ships the bundle so Funwae, Buoychong, and VibeCherry teams can share the same append-only history.
Cards establish who is acting. Events reference card_id so permissions, tone, and provenance flow through every trail.
GlyphIR semantics annotate each event before it lands in Tongbuku 同步库, keeping context reusable for models and audits.
Experiences, ops surfaces, and research sandboxes emit trails that Tongbuku 同步库 stores and VibeCherry/Funwae render as views.
FAQ
Tongbuku 同步库 complements your primary datastore. It handles append-only history, sync, and replay while you keep transactional state wherever you like.
