docs(examples): add tested deletion-recovery and keep-local editor recipes - #57

Conversation
…cipes Complete priority 2 of proposal 0006 with copyable host code that uses only the store's public methods, executed by the client suite through stream events. - retainRecoveryCopy keeps a detached copy of one fixed UID's draft and unsaved edits from the moment it starts, refreshed on every store notification, so work typed just before a deletion or snapshot pruning can be copied out afterwards. The copy is bound to the original identity, expires after a host-chosen lifetime, is released by dispose(), and is never applied or reconciled: a replacement UID opens clean. - keepLocal resolves a conflict in favour of the local value: capture it (or its absence), revert, and reapply it in one synchronous call, leaving an ordinary edit against the reviewed version. It covers nested paths, deletions both ways and whole arrays, refuses a path a policy or later redaction made read-only without changing anything, and leaves unrelated edits and conflicts alone. The saving and Vue guides and the examples index link to the recipes, and proposal 0006 marks priority 2 complete. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe change adds two editor recipes: one retains a removed object’s draft and edits for recovery, and one keeps local values during conflict resolution. Tests exercise both recipes against stream-store events. Example documentation and guides link to the recipes. ChangesEditor recipes
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Other Merge Risk: 🔵 Low · up to A recovery copy can appear while its object is live again. This is a narrow, fixable lifecycle error; merge with owner awareness or clear the removal state first. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Exposure is limited to optional editor helpers using existing store controls. However, synchronous callbacks can interrupt keep-local resolution, and recovery state is inconsistent when the same UID reappears. Production adoption and authorization context are not established.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Clear removedAt when the UID returns.
capture sets removedAt one time and never resets it. A UID can leave the store and come back. For example, removeResource runs and the stream later sends added with the same UID, or adoptSaved upserts a pruned UID. In that case, capture refreshes last, but removed stays true. copy() then returns a copy while the live object exists. This breaks the documented contract that the copy is null "while it still exists". The original removedAt also starts the expiry clock too early.
Proposed fix
const draft = store.draft(uid);
+ removedAt = undefined;
const { apiVersion, kind, metadata } = draft;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Completes priority 2 of proposal 0006: tested deletion-recovery and keep-local recipes. They are copyable host code in
examples/editor-recipes/(README,recoveryCopy.ts,keepLocal.ts). They use only the store's existing public methods, add no library API, and are executed by the client suite through stream events (applyStreamEvent), as the connector delivers them.Deletion recovery copy
retainRecoveryCopy(store, uid, { retainMs })keeps a detached copy of one fixed UID's draft and unsaved edits. It takes the copy as soon as it starts, and again on every store notification while the object exists. After adeletedevent or snapshot pruning, the copy stays available for explicit copy-out; it never tries to read the removed draft.retainMs, anddispose()stops listeningKeep-local resolution
keepLocal(store, uid, path)captures the local value (or its absence), callsrevert, and reapplies the value in one synchronous call. The result is an ordinary edit against the reviewed server version.captureSavebinds the reviewed versionnullin the patch), and a value the server deleted comes backstatusand a path redacted after the conflict returnfalse, changing nothingBefore writing the recipe I checked it against current behavior:
revertclears the conflict and the reapplied value is never re-flagged. No helper was added to the library; nothing in the repository repeats this code.The saving guide, the Vue guide (which said the recipe was pending) and the examples index link the recipes. Proposal 0006 marks priority 2 complete.
