Closes #73

Summary

  • replace broad gh project view, field-list, and item-list observation with one bounded, paginated GraphQL reader
  • page Project fields, items, labels, field values, and linked pull requests independently with identity, cursor, duplicate, and completeness checks
  • preserve REST issue/dependency evidence, exact operation ordering, and authoritative rereads after every attempted write
  • keep provider failures timed out, bounded, normalized, and redacted

Evidence

  • focused source/adapter/reconciliation/verifier suite: 4 files, 240 tests passed
  • post-Apply shared controls to Owner Application review #66 npm run verify: 469 unit tests, 103 database checks, 16 mobile/desktop access journeys, 8 Worker journeys, production build, secret scan, 33 browser tests with 5 expected skips, and Worker smoke passed
  • independent Standards review: PASS
  • independent Spec review: PASS
  • live no-op reconciliation: 30 GraphQL points versus the 261-point baseline (88.5% reduction); the plan remained a verified no-op
  • npm run verify:board: 46 current items and all tracker invariants passed

Safety

No database migration, user-data, authentication, authorization, tracker-policy, or credential changes. Existing write-time authoritative rereads and exact approved remaining-operation checks remain intact. Rollback is a code revert.

Summary by CodeRabbit

  • Improvements

    • Improved reliability when loading GitHub Project data, including large projects and paginated results.
    • Added stronger validation for incomplete, duplicated, or inconsistent project information.
    • Linked pull requests are captured directly with project items for more accurate status and provenance tracking.
    • Improved handling of malformed responses and provider errors while reducing unnecessary error details.
    • Reduced redundant data loading for faster, more consistent project updates.
  • Tests

    • Expanded coverage for pagination, validation, duplicate detection, safety limits, and linked pull-request handling.

📝 Walkthrough

Walkthrough

The pull request replaces separate GitHub Project reads with bounded GraphQL readProjectEvidence() calls. It validates pagination and identities, normalizes field values, includes linked pull requests, updates adapter and mutation consumers, and expands test coverage.

Changes

Project evidence consolidation

Layer / File(s) Summary
Bounded GraphQL connection validation
scripts/lib/rentcottage-gh-source.mjs
Shared limits and helpers validate pagination metadata, totals, identities, cursor progress, truncation, and safety limits.
Consolidated Project evidence flow
scripts/lib/rentcottage-gh-source.mjs, scripts/rentcottage-gh-source.test.mjs
readProjectEvidence() replaces separate project, field, item, and linked pull-request reads. It paginates nested connections, validates anchors, normalizes values, and supports mutation reads.
Adapter and schema contract updates
scripts/lib/rentcottage-github-adapter.mjs, scripts/lib/rentcottage-github-schema.mjs, scripts/rentcottage-github-adapter.test.mjs
The adapter consumes consolidated evidence and item-linked pull requests. Schema validation now requires structured linked pull-request records and checks their field for uniqueness.
Evidence and adapter validation coverage
scripts/rentcottage-gh-source.test.mjs, scripts/rentcottage-github-adapter.test.mjs
Tests cover bounded queries, nested pagination, identity and duplicate detection, malformed responses, mutation freshness, error redaction, and linked pull-request deduplication.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to bf09b

The PR substantially reduces reconciliation GraphQL usage while preserving authoritative rereads and existing checks, but add-project-item still performs an unusually broad read during writes and duplicated linked-pull-request validation could diverge over time. It is mergeable with explicit owner awareness and follow-up on these bounded risks.

Make the call-count assertion independent of test setup.

toHaveBeenCalledTimes(2) counts the setup call at line 236 plus the adapter call. The assertion therefore does not prove that observe reads evidence once. The new test at lines 312-325 already uses source.readProjectEvidence.mockClear() before observing. Apply the same pattern here.

Clarify the self-anchored item validation.

requireItemAnchor(item, item, repository, context) compares the item with itself. Only the shape checks and the repository check apply here. A dedicated shape validator, or a comment, would make the intent explicit and prevent a future reader from assuming a cross-page comparison happens at this line.

255-262: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Make the readProjectEvidence call count unambiguous.

The test calls await source.readProjectEvidence() during setup, and the adapter calls it once during observe. Line 261 therefore asserts 2. The assertion looks like the adapter reads Project evidence twice, which it does not.

The test at Lines 312-313 already solves this with mockClear(). Apply the same pattern here, or expose the fixture evidence object directly instead of awaiting the mock for setup.

♻️ Suggested change
-    expect(source.readProjectEvidence).toHaveBeenCalledTimes(2);

729-734: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Consider a lighter read for add-project-item.

add-project-item needs only project.id, but readProjectEvidence() now paginates fields and items and runs per-item label, field-value, and linked-pull-request follow-ups. The previous readProject() read only the Project coordinates. Each add-project-item operation now pays the full evidence cost.

If the write path executes several operations per run, this increases GraphQL usage on the write path while the read path savings are the PR goal.

One option is a bounded project-identity-only query for this operation, reusing requireProjectAnchor and hasFreshProjectCoordinates.

513-658: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider extracting the per-item nested pagination into helpers.

The for (const item of items.nodes) body now contains three inline pagination loops, three embedded GraphQL documents, and the normalization step. The function is long and hard to change safely.

Extract readItemLabels(item), readItemFieldValues(item), and readLinkedPullRequests(item, linkedValue, fieldCursor). Keep the current validation order and error messages so the fail-closed tests still pass.

This is a readability change only. Defer it if you prefer to keep the diff small.

Extract the linked-pull-request predicate and reuse it in the adapter.

This inline predicate is identical to isLinkedPullRequestResponse in scripts/lib/rentcottage-github-adapter.mjs Lines 130-138. Two copies of the same shape rule can drift when the provider payload changes.

Export this predicate and reuse it in the adapter.

The inline predicate at Lines 56-61 is identical to isLinkedPullRequestResponse in scripts/lib/rentcottage-github-adapter.mjs Lines 130-138. Both validate the same records on the same path. If one copy changes, the other can silently diverge and accept a shape the source no longer emits.

421-511: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff

Consider extracting the repeated Project-page read pattern.

The field-page loop and the item-page loop repeat the same four steps: read a page, check user.login, call requireProjectAnchor with projectId, then call appendConnectionPage. The two inline queries also duplicate the base user { login projectV2 { ... } } selection. The nested loops below repeat an analogous pattern for labels and field values.

readProjectEvidence is now about 250 lines. A helper such as paginateProjectConnection({ state, buildQuery, connectionFrom, identityFrom }) would remove the duplication and keep each fail-closed check in one place.

This is a maintainability suggestion only. The current control flow and validation are correct.

26-79: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider exposing the evidence object instead of reading it through the mock.

readProjectEvidence resolves the same evidence reference on every call. Tests therefore mutate the fixture by calling the mock itself, which also records an invocation. Two tests must call mockClear() before they assert call counts (Lines 255 and 313). The other mutation sites do not clear, so a later call-count assertion in those tests would fail for a reason unrelated to the code under test.

Returning evidence alongside the mocks removes the coupling.

♻️ Proposed refactor
   return {
+    evidence,
     assertSupported: vi.fn().mockResolvedValue(undefined),
     readProjectEvidence: vi.fn().mockResolvedValue(evidence),

Call sites then use const { items } = source.evidence; instead of const { items } = await source.readProjectEvidence();.

484-548: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extract the shared Project connection pagination loop.

The field loop at Lines 489-515 and the item loop at Lines 522-548 duplicate the loops at Lines 595-621 and Lines 629-662. They differ only in the node selection string, the connection name, and the context prefix. A future change to the owner check or the project anchor must be applied in four places.

Extract one helper that accepts the connection name, the node selection string, and the context prefix, and returns the accumulated connection state.

308-318: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

The project.items.totalCount and project.fields.totalCount values are now unused.

Removing the cross-read comparisons is correct, because a single consolidated read made those comparisons tautological. After the removal, isProjectResponse (Lines 24-27) is the only consumer of project.items.totalCount and project.fields.totalCount. No check compares them to anything.

Consider dropping these two nested count fields from the source payload and from isProjectResponse, or documenting why the shape is retained. The truncation checks at Lines 308 and 319 already use the top-level totals.

590-662: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Consider extracting the Project connection paginator.

readFreshProjectCoordinates (Lines 484-548) and readProjectEvidence (Lines 590-662) repeat the same loop: build a cursor query, check user.login, call requireProjectAnchor with projectId, then call appendConnectionPage. Only the context string and the node selection differ.

Extract a helper that takes the node selection, the connection name, and the context, and returns the accumulated nodes. This removes four near-identical blocks and keeps the anchor checks in one place.
