Stacked on #167. Follows the graph #157 made visible to its conclusion: sync now consumes it instead of re-deriving its own.

The evidence

Two functions decided what a source is. resolveSources (config/normalize.ts) builds the resolved graph doctor and generate --json report; resolveRemoteSources (sync/sync.ts) rebuilt a second one from the collections map for leadtype sync to clone from. Same dedup key, different rules — and three confirmed-by-execution bugs live in the gap:

  1. Sparse mismatch silently misrepresented. Normalize merged two collections on one (repository, ref) without comparing sparse, so sparse: ["docs"] beside sparse: ["packages"] normalized into one source claiming ["docs"] serves both — while sync threw. Doctor and generate --json presented a coherent, wrong graph for a config that cannot sync.
  2. Mixed explicit/default cacheDir. Normalize backfilled (existing.cacheDir ??= …) when only one collection set cacheDir, resolving to one source at the explicit dir; sync compared resolved paths, gave the unset collection the default cache dir, and threw "different cacheDir values" — contradicting normalize's own comment that cacheDir conflicts are "rejected here rather than at clone time".
  3. Source id collision with the implicit local source. A git source the user names local beside a repository-less collection produced two id: "local" entries in resolved.sources — and ids are the join key for sync output, doctor, and every JSON surface.

The design

Validation moves into resolveSources. A shared acquisition must agree on its sparse set (compared as a set — order is irrelevant to git sparse-checkout) and its cache dir (compared as resolved paths, so an explicit cacheDir that spells out the default location stays valid, as it always synced). Duplicate source ids are rejected outright. Each error names the collections, the disagreement, and the fix, at normalize time — where doctor and JSON read from.

Sync's derivation becomes a projection. resolveRemoteSources is gone. projectRemoteSources filters resolved.sources to git sources and resolves cacheDir against the config dir — nothing else. syncCollections becomes syncSources and takes resolved.sources itself; both callers (leadtype sync, generate --sync) hand it the graph from the first normalization pass — the only pass that saw authored source names. Exactly one place now decides source identity, sparse sets, and cache dirs. The sync CLI's repo#ref remapping is deleted: the synced source carries id, refKind, and collectionKeys directly.

External behavior is otherwise unchanged. Configs that synced before sync identically — same clone layout, same manifests, same output lines. Configs sync rejected are now rejected at config load, with messages at least as specific. A git source named local with no local collections stays valid, since there is no collision to misread.

Tests

Each bug has a regression test in normalize.test.ts, plus the parity cases that must keep working (order-insensitive sparse, explicit-cacheDir-equals-default, local-named source with no local collections). New in kind: a cross-subsystem agreement suite in sync.test.ts asserts, for a matrix of authoring shapes (flat, gitSource group, mixed, explicit/default cacheDir, sparse variants, local+remote), that the graph sync acts on is the graph normalize reports and that resolveCollection reads every collection from its source's checkout — the class of test whose absence let each subsystem pass while disagreeing with the other.

Verification

883 tests pass (bun run test), lint clean, tsgo --noEmit clean for the package. bun run check-types at the workspace level still trips the pre-existing parallel-build race on this stack; that fix is #166, off main.

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • Bug Fixes
    • Improved source synchronization consistency by using resolved source configurations directly.
    • Added validation for conflicting cache directories, sparse paths, and duplicate source IDs.
    • Prevented collisions between authored sources and the implicit local source.
    • Preserved existing clone layouts, manifests, outputs, and synchronization behavior for valid configurations.
    • Invalid source configurations now fail earlier with clearer errors.

Walkthrough

The change centralizes source identity and acquisition validation during configuration normalization. Synchronization now consumes resolved sources, while CLI commands and tests use the syncSources API.

Changes

Resolved source graph synchronization

Layer / File(s) Summary
Source normalization and validation
packages/leadtype/src/config/normalize.ts, packages/leadtype/src/config/normalize.test.ts
Normalization resolves cache paths relative to the config directory, validates sparse paths and shared cache directories, and rejects duplicate source IDs.
Source projection and synchronization
packages/leadtype/src/sync/sync.ts, packages/leadtype/src/sync/sync.test.ts
SyncSource and projectRemoteSources preserve resolved source metadata. syncSources replaces collection-based synchronization and its tests cover configuration shapes and synchronization behavior.
CLI adoption and release metadata
packages/leadtype/src/cli/generate.ts, packages/leadtype/src/cli/sync.ts, .changeset/sync-resolved-graph.md
CLI commands pass resolved sources to syncSources. Sync reporting reads IDs, collection keys, and reference kinds from each result source.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 99fb9

The PR centralizes source resolution and adds validation while preserving sync behavior; remaining concerns are limited to minor maintainability follow-ups, so no actionable merge-blocking risk remains after normal checks and review.

I’m a rabbit with sources aligned,
Sparse paths sorted, cache rules defined.

Sync hops through the resolved graph again.
Carrots for tests, and a clean checkout tune!

ℹ️ No correctness issues found in the consolidation — two rough edges and a missing changeset.

Reviewed changes — full diff of the single commit 0e50cdd, plus the surrounding call graph (config/load.ts, config/project.ts, config/inherit.ts, cli/generate.ts, cli/doctor.ts) and a local run of the package test suite.

  • resolveRemoteSources deleted, projectRemoteSources added — sync no longer walks the collections map to rebuild its own (repository, ref) graph; it filters resolved.sources to git sources and resolves cacheDir against the config dir, copying id, refKind, sparse, and collectionKeys through unchanged.
  • syncCollectionssyncSources — the option is now sources: readonly ResolvedSource[] instead of a collections map, and SyncSourceResult.source / SyncResult.skipped carry the new SyncSource type (ResolvedRemoteSource & { id, refKind }).
  • Agreement validation moved into resolveSources — mixed explicit/default cacheDir and disagreeing sparse sets now throw at normalize time, and a new assertUniqueSourceIds rejects a git source authored as local beside repository-less collections.
  • cli/sync.ts remapping removed — the repo#ref → resolved-source lookup and its ?? entry.source.repository fallback are gone; the output loop reads id, refKind, and collectionKeys straight off the synced source.
  • Both callers hand over the first-pass graphcli/sync.ts and cli/generate.ts pass resolved.sources from the normalization that ran during config load.
  • Tests — three regression tests plus three parity tests in normalize.test.ts, and a six-shape cross-subsystem matrix in sync.test.ts.

I verified the load-bearing invariant myself: the configDir at both syncSources call sites (path.dirname(loaded.path)) is the same one load.ts:1019 passed to normalizeDocsConfig, expandGitSources flattens sources groups onto collections before resolveSources validates them, and inherit.ts never touches repository/ref/cacheDir/sparse — so keeping the first-pass graph across the re-normalize in generate.ts:1710 is sound. syncSources and projectRemoteSources are not public API, so no caller can supply an unvalidated graph. The 10 cli.test.ts failures I saw locally are environmental (packages/leadtype/dist isn't built); sync.test.ts and normalize.test.ts pass.

⚠️ Three new config-load errors ship without a changeset

This PR turns three previously-accepted config shapes into hard throws at config load, and adds no .changeset entry. Every prior commit on this stack that touched normalize.ts shipped one (canonical-config-api.md, git-source-groups.md, resolve-project.md), and the existing entries don't cover this: git-source-groups.md documents the sparse agreement rule, but nothing describes the explicit-vs-default cacheDir rule or the local id collision — nor that the error surface moved from leadtype sync to config load, so doctor, generate without --sync, and createDocsProject now fail on configs they previously tolerated.

Technical details
# Missing changeset for the validation move

## Affected sites
- `.changeset/` — no entry added by this PR; `git log --name-only` shows every prior
  `normalize.ts` commit on this stack paired with one.
- `packages/leadtype/src/config/normalize.ts:270-291` — new explicit-vs-default `cacheDir` rejection.
- `packages/leadtype/src/config/normalize.ts:358-372` — new duplicate-source-id rejection.
- `docs/concepts/config-model.mdx:87-115` — documents the source graph but not the agreement
  rules a shared acquisition must satisfy.

## Required outcome
- A changeset entry describing which config shapes now fail, and that they fail at config load
  rather than at `leadtype sync`.
- Decide whether `docs/concepts/config-model.mdx` should state the agreement rules alongside the
  source-graph shape it already documents.

## Open questions for the human
- Is this stack releasing as one changeset owned by #167, or does each PR carry its own? If the
  former, the `resolve-project.md` entry needs amending rather than a new file.

ℹ️ The rewritten leadtype sync output has no test covering it

runSyncCommand has no test anywhere — there is no cli/sync.test.ts, and cli.test.ts never drives the sync subcommand. This PR rewrites its output construction (cli/sync.ts:145-155), deleting the resolvedById lookup and both ?? fallbacks, on the strength of a claim in the PR body that the output lines are unchanged. Nothing in the suite would catch it if a named gitSource group stopped reporting its authored id, or if the mutable-ref warning stopped firing.

Technical details
# `runSyncCommand` output is uncovered

## Affected sites
- `packages/leadtype/src/cli/sync.ts:145-163` — output loop and mutable-ref warning, rewritten
  in this PR, with no test exercising it.

## Required outcome
- A test that drives `runSyncCommand` with a fake `SyncCliIo` and a config containing a named
  `gitSource` group plus an anonymous flat collection, asserting the printed id is the authored
  source name for one and `repository#ref` for the other, and that a mutable ref produces the
  stderr warning.

## Suggested approach (optional)
- `syncSources` takes an injectable `runner`, but `runSyncCommand` doesn't thread one through, so
  the test needs a real temp dir + config file, or a small seam for the runner. The existing
  `seedFakeCheckout` helper in `sync.test.ts` covers the checkout side.

ℹ️ Nitpicks

  • normalize.ts:239-247 (the pre-existing both-explicit cacheDir check) compares raw authored strings while the sibling check this PR adds at :270-291 compares path.resolved paths. Not a regression — the string check already ran at load time before this PR — but now that this function is the sole owner of cacheDir agreement, the two halves disagree on strictness: "./vendor/acme" beside "vendor/acme" is rejected, while "./vendor/acme" beside the default that resolves to the same place is accepted.

ℹ️ No new issues in 0e3658e — both prior inline findings are fixed correctly. Holding off on approval only because the changeset gap flagged in the previous review is still open.

Reviewed changes0e3658e, the single commit since the prior pullfrog review of 0e50cdd, plus the surrounding callers (config/load.ts, config/project.ts, cli/generate.ts) and a local run of normalize.test.ts + sync.test.ts and tsgo --noEmit.

  • cacheDir equivalence no longer rebases onto cwdresolveSources computes resolveBase as configDir ?? (configPath ? path.dirname(configPath) : "."), so the accept/reject decision is derived from the config being normalized rather than the process working directory.
  • Added a discriminating regression test for itnormalize.test.ts:366-404 drives the shared configPath-only normalize() helper with an absolute cacheDir equal to the config-relative default. That case throws under the old resolveBase = "." (vitest's cwd is packages/leadtype, not /repo), and the sibling test at :336-364 could not catch it because its relative default dir resolves identically under any base.
  • Removed the tautological projection assertionsync.test.ts:990-1008 now derives its expectation from resolved.sources.filter(kind === "git") with path.resolve(configDir, cacheDir ?? defaultCacheDir(...)) computed inline, instead of comparing syncSources' output against the same projectRemoteSources call it made internally.

I confirmed the resolveBase change is behaviour-neutral for every in-repo production path: load.ts:1019, project.ts:316-320, project.ts:413-416, and generate.ts:1710-1713 all pass a real configDir, so only external configPath-only callers and the test helper see a different base. normalize.test.ts + sync.test.ts pass (82 tests) and tsgo --noEmit is clean for the package.

@KayleeWilliams
KayleeWilliams force-pushed the dx/sync-resolved-graph branch from 0e3658e to 1afce16 Compare August 15, 2026 18:23
`leadtype sync` re-derived its own source graph from the collections map
(resolveRemoteSources), disagreeing with the graph resolveSources reports
to doctor and `generate --json`. Three bugs stemmed from the duplication:
a sparse disagreement normalized into a coherent, wrong graph that sync
then rejected; a mixed explicit/default cacheDir was backfilled by
normalize but rejected by sync; and a git source named "local" produced
two sources with the same id.

The agreement checks now live in resolveSources — sparse sets and cache
dirs (compared as resolved paths, so an explicit cacheDir spelling out
the default stays valid) fail at normalize time, and a duplicate source
id is rejected outright. Sync's derivation is gone: projectRemoteSources
is a projection of resolved.sources, and syncSources takes the graph
itself, so exactly one place decides source identity, sparse sets, and
cache dirs. The sync CLI drops its repo#ref remapping — the id, ref
kind, and dependents come straight off the synced source.

New agreement tests assert, across a matrix of authoring shapes, that
the graph sync acts on is the graph normalize reports and that
resolveCollection reads from the same checkouts.
When normalizeDocsConfig got configPath but no configDir, the
cacheDir-equivalence check fell back to process.cwd(), so an explicit
absolute cacheDir spelling out the config-relative default was rejected
or accepted depending on invocation cwd. Derive the fallback base from
path.dirname(configPath), keeping cwd as the last resort only when
neither is known.

Also pin the sync graph agreement test against expectations derived
independently from the resolved graph's git entries — it previously
compared projectRemoteSources against itself, so it could never fail.

Rebased onto origin/main after #167 landed. Still two distinct commits: sync now consumes the first-pass resolved source graph, and cacheDir equivalence is still resolved against the config file's directory.

Important

The force-push carries no code change — but it retargets this PR onto main now that #167 has merged, which settles the changeset question the first review left open.

Reviewed changes — the delta since the prior pullfrog review of 0e3658e: two successive force-pushes that replayed the same two commits, the second of which moves this PR off the stack and onto main. I re-derived the patch equivalence and re-verified the integration against the new base.

  • Confirmed the patch is byte-identicalgit range-diff dcad26ff..1afce169 76af4e4e..8ba12b6a reports = for both commits, so resolveSources' three relocated validations, projectRemoteSources, the syncCollectionssyncSources rename, and the rewritten cli/sync.ts output loop are unchanged from the reviewed version.
  • Retargeted the base from the merged dx/157-resolve-project to mainmain gained the --docs-dir parsing, diagnostic-channel, and nav-locale series (966adae6..76af4e4e) on top of the old base, so the merged result differs even though the diff does not.
  • Re-verified the load-bearing invariants against the new base — all four production normalizeDocsConfig callers still pass a real configDir (load.ts:1328, project.ts:600, project.ts:770, generate.ts:1685), and a repo-wide sweep found no other caller in any package, so the resolveBase fallback added in 0e3658e still only affects external callers. Both re-normalize sites still carry the first-pass sources forward (generate.ts:1694, project.ts:797), and no new base commit references the renamed or deleted sync API.
  • Confirmed the validation move is not newly fatal anywhere on the new base — every path that reaches resolveSources already catches: generate.ts:1657-1713 wraps the whole config-load block, so watch-mode rerun() degrades to a reported failure rather than tearing the watcher down; doctor.ts:391-423 converts throws into a config.invalid issue; nav.ts:258-350 and lint/cli.ts:226-253 handle their own. project.ts:940-947 is the only base code touching resolved.sources after normalization, and it only appends collectionKeys to the local source, so assertUniqueSourceIds cannot be bypassed.
  • Re-ran the suite on the new base — 889 pass / 10 fail in packages/leadtype, the 10 all in src/cli.test.ts and all environmental (packages/leadtype/dist unbuilt); normalize.test.ts + sync.test.ts = 82 pass; tsgo --noEmit clean for the package.

⚠️ The rebase removes the reason the changeset could be deferred

The first review flagged that three previously-accepted config shapes now throw at config load with no .changeset entry, and left open whether the stack would ship one changeset owned by #167. That question is now answered: #167 has merged, and its entries sit unreleased on main where a Version Packages run can consume them at any time — so amending one is no longer a safe option, and this PR needs its own. Without it, the move of the error surface from leadtype sync to config load reaches users undocumented, and doctor, nav, lint, generate without --sync, and createDocsProject all start rejecting configs they previously tolerated.

Technical details
# Missing changeset, now unbackstopped by the merged stack

## Affected sites
- `.changeset/` — this PR adds no entry (its diff touches 6 files, none under `.changeset/`).
- `.changeset/git-source-groups.md`, `.changeset/resolve-project.md`,
  `.changeset/canonical-config-api.md`#167's entries, now on `main` and unreleased.
  `git-source-groups.md` states the `sparse` agreement rule but nothing about the
  explicit-vs-default `cacheDir` rule, the `local` id collision, or the relocation of the
  error surface.
- `packages/leadtype/src/config/normalize.ts:265-295` — new explicit-vs-default `cacheDir`
  rejection.
- `packages/leadtype/src/config/normalize.ts:296-306` — new `sparse` disagreement rejection.
- `packages/leadtype/src/config/normalize.ts:354-376` — new `assertUniqueSourceIds` rejection.
- `docs/concepts/config-model.mdx:87-115` — documents the source graph shape but not the
  agreement rules a shared acquisition must satisfy.

## Required outcome
- A changeset owned by this PR naming which config shapes now fail, and stating that they fail
  at config load rather than at `leadtype sync` — so `doctor`, `nav`, `lint`, `generate`
  without `--sync`, and `createDocsProject` are covered, not just `sync`.
- A decision on whether `docs/concepts/config-model.mdx` should state the agreement rules
  alongside the source-graph shape it already documents.

ℹ️ The changeset the previous review asked for has landed and reads accurately — one suggestion on its bump level.

Reviewed changes99fb9a4, the single commit since the prior pullfrog review of 8ba12b6. git show --stat 99fb9a4 confirms it touches one file (+9, no deletions), so every code path reviewed at 8ba12b6 is byte-identical and nothing in the earlier verification needed re-deriving.

  • Added .changeset/sync-resolved-graph.md — a patch entry naming all three previously-accepted config shapes that now throw (silently-merged sparse disagreement, mixed explicit/default cacheDir, a git source named local colliding with the implicit local source), and stating the error surface moved to config load rather than leadtype sync.

I checked the entry's claims against the code rather than the PR body: the three shapes match the throws at normalize.ts:265-295, :296-306, and assertUniqueSourceIds at :354-376; "fail when the config loads" is the right generalization, since it covers doctor, nav, lint, generate without --sync, and createDocsProject, not just sync. The prior review's second ask — whether docs/concepts/config-model.mdx should state the agreement rules — is still open, but that page documents only the source-graph shape and says nothing about cacheDir or sparse, so nothing there is now false; it is an enhancement, not drift.

ℹ️ Nitpicks

  • The entry says a shared acquisition's cache directory is "compared as resolved paths", but only the explicit-vs-default comparison resolves paths (normalize.ts:265-295). The both-explicit check at normalize.ts:239-247 still compares authored strings, so "./vendor/acme" beside "vendor/acme" is rejected even though they resolve to the same place — a reader of the changelog would infer a normalization that doesn't hold across the board.

This entry is marked patch, but it makes configs that previously loaded throw at config load — a sparse-disagreeing config that only ever ran generate (never sync) worked before and now fails to load. On a 0.x line minor is the lever for that, and this repo already ships breaking removals under it (0.4.0 retired markdownEngine and the leadtype/remark export as a Minor Change). The aggregate release bump is minor regardless thanks to the unreleased entries on main, so the practical stake is the changelog heading a config break lands under — decline if you read the affected configs as already-broken rather than newly-rejected.

Technical details
# Bump level understates a config-load break

## Affected sites
- `.changeset/sync-resolved-graph.md:2``"leadtype": patch`.
- `packages/leadtype/src/config/normalize.ts:296-306` — the `sparse` disagreement throw, the one
  shape reachable by a user who never runs `leadtype sync`.

## Required outcome
- The changelog signal matches the compatibility impact: a consumer on `0.4.x` taking a
  patch-range update should not find their config newly rejected without a minor-or-greater bump.

## Suggested approach (optional)
- Change the frontmatter to `"leadtype": minor`, matching `.changeset/git-source-groups.md` and
  the other unreleased entries this will release alongside.

## Open questions for the human
- Do you classify the three rejected shapes as already-broken (patch-worthy fix) or as previously
  valid (minor-worthy break)? Only `sparse` disagreement is reachable without `sync`; the other
  two already threw at clone time.

Learning: In this repo, `.changeset/*.md` files must not start the body with an H1/first-line heading (`#`) immediately after the YAML frontmatter. The changesets tool inlines the body as bullet entries into `CHANGELOG.md` during release, and a leading `#` heading would break the generated changelog format. As a result, MD041 (`first-line-heading`) warnings for files under `.changeset/` are expected false positives and should be ignored.

1-3: Bump level may understate the change.

The entry declares patch. The body states that configs which previously loaded now fail at config load, and the sync API export changed. I raised the export-surface question on packages/leadtype/src/sync/sync.ts Lines 494-508; resolve it there and adjust this bump if the public surface changed.

Default cache-directory expectations duplicate the defaultCacheDir layout rule. Both test files assert a hardcoded .leadtype/sources/<slug>@<ref> string. The layout comes from defaultCacheDir and the slug from repositorySlug, both in packages/leadtype/src/sync/sync.ts. A change to either rule leaves these literals stale.

Replace the as string assertion with a narrowing expression.

The XOR comparison at Line 270 does not narrow either cacheDir, so Line 274 needs an assertion. Derive explicitDir from a branch that narrows instead. The rest of the block stays unchanged.

Give sourcesFor an explicit config base.

sourcesFor calls normalizeDocsConfig without configPath or configDir. The new cacheDir equivalence check in packages/leadtype/src/config/normalize.ts then resolves against ".", which is the process working directory. No current case in this file mixes an explicit cacheDir with a default one, so the tests pass today. Any future case added through this helper would become cwd-dependent.
