How this repo uses loro-crdt correctly — mergeable child containers vs the deprecated getOrCreateContainer, what a container choice costs in oplog bytes, rich-text marks, and how to measure a Loro claim against the installed version instead of trusting a doc page. Use when adding or changing anything that opens a container, stores a collection, exports/imports a document, or when a CRDT merge is losing data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Using loro-crdt in this repo Loro is where this project's data actually lives, and its failure mode is the worst kind: **a wrong container choice loses data with no conflict, no error, and both replicas agreeing on the truncated result.** Nothing goes red. The loss is found, if ever, by a person noticing their reply is gone. So the rule here is the repo's rule everywhere else, sharpened: **a claim about Loro is worth what its measurement is worth.** The version is pinned in `pnpm-workspace.yaml` (`loro-crdt: "1.13.6"`), the API has changed under this repo more than once, and `loro.dev` is not reachable from this environment anyway. What IS reachable and authoritative is shipped inside the package — see "Where the answers actually are" below. ## The rule: a lazily-created child container must be mergeable `map.getOrCreateContainer(key, new LoroMap())` mints a **regular op-id** child. Two replicas that each open the same key having never seen the other's end up with two containers, and the map's conflict resolution keeps one and hides the other. Measured on 1.13.6 — two peers, no common ancestor for the key, each writing one entry: | opened with | both replicas read | …

How to install
mdr add kamiazya/whiteboard/loro-crdt-usage@sha256:d09195e28b7ad084The line at the top of this page pins the label git:20261016.bbfc32d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
