Keep every lesson you make, not just the last one - #45

Conversation
The editor held exactly one working document. IndexedDB has no reason to hold one lesson rather than fifty, so it now holds as many as you make: a **library**, with a metadata record and a document per lesson, and a **Lessons** panel to switch between them. **Opening a lesson stops being destructive.** Three flows — open one of your hub lessons for editing, fork a lesson, import a Word or JSON file — each replaced whatever was on screen, and each needed a "Replace your current work?" dialog to warn you first. All three now land in the library beside what you were doing: an edit reopens the copy this device already has (never a second copy of the same lesson), and a fork or an import becomes a lesson of its own. The dialogs, the `pendingEdit` state and `docHasContent` are gone with them, and "fork into a new lesson" now leaves the lesson it came from in the list, still attached to its hub row, rather than detaching the one document there was. **A repository per lesson, named by the lesson.** `repoIdFor(lessonId, localId)` gives each local lesson a git repo of its own — its library id until it is published, the hub's id afterwards — so switching lessons switches histories, with nothing in the version-control layer knowing it happened: `repoId` changes and the setup effect re-runs. `adoptDraftRepo`, `forkLessonRepo` and `forkLocalRepo` take the repository they act on instead of assuming the single `draft` slot, and `useLessonGit.reload()`/`discard()` are deleted, since nothing replaces a repository under its own id any more. **Migrating costs no git objects.** The old working document becomes the library's first lesson under the id `draft` — deliberately, because that is the name its repository already has on disk and a local lesson's id *is* its repo id, so the whole timeline carries across untouched. Verified against a seeded v1 database: the lesson, its hub attachment and its history all survive. Two bugs found while testing. Hydration creates the first lesson on an empty device, so StrictMode's double-invoke raced and left an untitled twin — it is guarded by a ref now, not a cancellation flag, because the effect writes. And a repository whose HEAD names an object that never reached disk (a reload landing mid-commit; LightningFS persists contents and its index separately) left the lesson with no history at all, permanently: setup now restarts such a repository, which for a published lesson means cloning its history back from the hub. Documents are split from their metadata across two object stores so listing the library reads the titles and not the lessons, and `saveLessonDoc` no-ops on a lesson that has been deleted, so a debounced save can't leave an orphan body behind.

Reviewer's GuideThis PR replaces the single “working document” model with a local lesson library stored in IndexedDB, gives each lesson its own git repository keyed by its library/hub id, and introduces a Lessons panel plus routing/docs to manage and switch between these local lessons without destructive workflows or lose history, including migrations from previous storage layouts and fixes for two git-related bugs.

Hey - I've left some high level feedback:
- Most library operations in EditorPage (duplicateLocalLesson, removeLocalLesson, applyEdit edit path) repeatedly call listLessons/getLesson in series and then refresh the whole list, which may become noticeably slow as the number of lessons grows; consider reusing the existing localLessons state where possible and avoiding a full list reload when you already know the new library shape.
- In LessonsDialog, rename/delete/duplicate all optimistically clear local UI state before the async mutation runs, but any failure in the underlying IndexedDB/git operation will leave the list visually updated even though the change didn’t stick; adding minimal error handling/notification or rolling back naming/confirming on failure would make these flows more robust.

In `@apps/docs/docs/web-app/local-lessons.md`:
- Around line 48-62: Update the lesson identity documentation to distinguish the
local lesson ID from the repository ID: describe metadata and documents as keyed
by the local lesson ID, use <repoId> in the repository path, and revise the
surrounding statement that currently says all three use the same ID. Keep the
terminology consistent with repoIdFor and repoCtx.
In `@apps/web/src/components/LessonsDialog.jsx`:
- Around line 300-310: Route the “New lesson” button handler through the
existing run mechanism so busy is set for the entire asynchronous creation flow
and a second press is ignored. Update the handler around onCreate and onClose to
use run, preserving the current close behavior only after successful creation.
- Around line 219-283: Update the delete confirmation flow in LessonsDialog so
DropdownMenuContent.onCloseAutoFocus prevents Radix’s default focus restoration
and focuses the confirmation Button after the trigger unmounts; add
disabled={busy !== null} to the “Keep it” Button to match the other action
controls.
In `@apps/web/src/locales/en/editor.json`:
- Around line 6-7: Update the wordImportWarning.body3 translation to remove the
outdated claim that current work is replaced after confirmation, so it
accurately reflects that Word imports create a separate lesson via
handleImportFile and no overwrite confirmation exists.
In `@apps/web/src/pages/EditorPage.jsx`:
- Around line 466-491: Update the hydration effect’s async IIFE to catch and
report migration or lesson-loading/creation failures, while ensuring
setHydrated(true) runs in a finally block so the editor exits its loading state.
Preserve the existing in-memory fallback behavior and avoid enabling persistence
for a missing lesson when hydration fails.
- Around line 965-989: Update the existing-record branch in the lesson edit flow
to preserve the current local document before saveLessonDoc(existing.id,
nextDoc) overwrites it, using the lesson repository’s existing commit/history
mechanism; alternatively, ensure the notify call after adoptRecord clearly
reports that the local copy was replaced and remains available in the history
panel.
- Around line 736-749: Update renameLocalLesson to persist the new title with
saveLessonDoc in both the open-lesson and non-open branches before calling
refreshLocalLessons; for the open lesson, keep savedDocRef synchronized with the
updated document so the debounced save does not rewrite it.
In `@packages/core/src/browser/git/fs.js`:
- Around line 67-78: The adoptDraftRepo flow must reconcile an existing lesson
repository instead of returning immediately when its destination config exists.
Update adoptDraftRepo to preserve or merge commits unique to draftRepoId into
the existing lesson repository, then remove the draft repository so later
cleanup remains correct; keep the current copy-and-remove behavior when the
destination does not exist.
In `@packages/core/src/browser/storage.js`:
- Around line 268-304: Update migrateToLibrary in
packages/core/src/browser/storage.js lines 268-304 to read back the draft record
and document after createLesson, returning before clearDocument when either is
missing; update packages/core/src/browser/storage.js lines 136-144 to verify the
document write before putLessonRecord. Use throwing imageStore write variants if
needed, while preserving swallowing variants for best-effort callers.

…es of it Three review bots, twenty comments. The bugs worth having are these. **Opening a hub lesson you already hold overwrote it.** The one flow left in the change that destroyed local work, on the page whose whole point is that it doesn't: the edit path reopened the device copy and then replaced its document with the freshly fetched one, discarding anything edited here since the last save to the cloud. It now adopts that copy exactly as it was left, refreshing only the metadata the hub is authoritative for. When the two documents differ it says so — the cause can be either side, and saving to the cloud already settles it, since the push refuses to overwrite a lesson that has moved on and offers the merge. **Repository recovery stranded published history.** Resetting an unreadable repo called `ensureRepo` directly, so a published lesson got an empty repository that every later open then found established enough to leave alone — its timeline unreachable for good. Both paths go through one `createRepo` now, which clones the history back from the hub whenever the lesson has one. **Two writes to one record could lose each other.** `saveLessonDoc` and `saveLessonMeta` each did a get-then-put in separate transactions, so a debounced document save that read first could put its stale copy back last and drop the hub id a publish had just set. Both now go through `updateLessonRecord`, which reads and writes inside a single transaction spanning both stores — which is also the deletion guard, so a save in flight when its lesson is deleted can no longer resurrect it or strand its document. **Two presses, two lessons.** The panel's New lesson button never entered the busy state, so a second press during the save-and-commit that precedes creation made a second untitled lesson — the twins the hydration guard exists to prevent, by another route. It runs through the same wrapper as every other action now. Also: hydration cannot leave the editor on its skeleton for ever (an IndexedDB open blocked by another tab on the old version is newly reachable — it reports the failure and carries on in memory); opening a lesson takes a request token, so a slow first click can't land after a second; renaming the open lesson writes through rather than waiting for the debounce, so the list doesn't show the old title; migration reads the lesson back before dropping the v1 keys, since every store write is best-effort and this is the only durable copy; deleting a published lesson also clears a repository left under its local id; the delete confirmation takes focus from the menu trigger it replaces, and failures in the panel are shown rather than swallowed. The Word-import warning still promised "your current work is replaced only after you confirm", which stopped being true when the confirmation was deleted. Docs: the local id and the repo id are no longer described as the same thing. Not taken: the `data-icon` suggestion on the row's icon-only button (that attribute marks an icon *beside text*, as VariationsDialog's identical button shows), and reusing cached lesson lists instead of re-reading them (the reads are metadata-only, and a stale list here is how a second tab's work goes missing).

CodeRabbit's second pass, and its main finding is a good one — older than this branch, but made permanent by the recovery path added to it. `fetchPack` already tells two failures apart: it returns null when a lesson genuinely has no published history, and throws when the hub couldn't be reached. Setup collapsed both with `.catch(() => null)`, so a lesson opened on a flaky connection got an *empty* repository, took a baseline commit of the document on screen, and from then on looked established to every later open: repository present, head readable, nothing to clone. The published timeline was never coming back. The throw propagates now — setup fails, nothing is written, and the next mount tries the clone again — and `noRepoRef` stops an explicit commit from scattering objects into the slot the clone is coming back to. Also: the panel's closing-focus override is scoped to the two actions that actually unmount the menu trigger. Rename and Delete replace it with a control of their own and take focus themselves; Duplicate leaves it in place, so Radix's own restoration is the right behaviour and gets it back. Verified all three in a browser — the name field, the trigger, and "Delete forever" respectively. And a failed refresh reports itself through the panel's error alert instead of going out as an unhandled rejection. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The editor held exactly one working document. IndexedDB has no reason to hold one lesson rather than fifty, so it now holds as many as you make: a library, with a metadata record and a document per lesson, and a Lessons panel to switch between them.
Opening a lesson stops being destructive
Three flows — opening one of your hub lessons for editing, forking a lesson, importing a Word or JSON file — each replaced whatever was on screen, and each needed a "Replace your current work?" dialog to warn you first. All three now land in the library beside what you were doing:
The dialogs, the
pendingEditstate anddocHasContentare gone with them.A repository per lesson, named by the lesson
repoIdFor(lessonId, localId)gives each local lesson a git repo of its own — its library id until it is published, the hub's id afterwards. Switching lessons therefore switches histories with nothing in the version-control layer being told:repoIdchanges and the setup effect re-runs.adoptDraftRepo,forkLessonRepoandforkLocalRepotake the repository they act on rather than assuming the singledraftslot, anduseLessonGit'sreload()/discard()are deleted — nothing replaces a repository under its own id any more.Migrating costs no git objects
The old working document becomes the library's first lesson under the id
draft. That is deliberate:draftis the name its repository already has on disk, and a local lesson's id is its repo id, so the whole timeline carries across without a single object being copied.Two bugs found while testing

In a real browser, on a real device library: fresh start, switching, duplicate (a real repo clone — the copy keeps the history and shares the commit oids), rename, deleting the open lesson, and the v1 → library migration against a seeded old-style database, whose lesson, hub attachment and history all survived.
