Closes #706

📝 Summary

#706 reported two things: a mem_save_prompt response whose id resolved to an unrelated entry from another project, and a cloud dashboard that kept showing 0 prompts afterwards.

The id was never stale. Prompts are numbered from user_prompts, a sequence independent of observations, so a prompt id in the low hundreds is normal while observations are in the thousands. What made it look stale is that the response named the id id, which invited reading it back through mem_get_observation — where it landed on whatever unrelated observation happened to hold that row number. This PR returns prompt_id so the identity names its own namespace.

The persistence was not broken. The dashboard half of the report was untested rather than defective. This PR adds the end-to-end and project-scoped sync coverage that proves it, per review feedback, so the closure claim rests on evidence instead of inference.

📂 Changes

File Change
plugin/pi/index.ts Normalize successful prompt saves to { prompt_id, status: "saved" }.
plugin/pi/test/native-tool-contract.test.mjs Load the extension and execute mem_save_prompt against a recording fetch: assert the session is created under the requested project before the prompt is posted to /prompts with that scope, and that the response echoes the server-assigned id as prompt_id.
plugin/pi/test/index-source.test.mjs Assert the prompt-scoped response identity.
internal/server/server_e2e_test.go TestPiPromptPersistenceE2E — replay the Pi wire sequence, read the prompt back from /prompts/recent and /prompts/search under its own project, confirm the returned id resolves to the content just written, confirm it carries a sync_id, and confirm another project cannot see it or resolve it as an observation.
internal/sync/sync_test.go TestCloudSyncPreservesPiPromptIdentityUnderProjectScope — the prompt enqueues an upsert mutation filed under its own project and keyed by its sync_id, then survives a cloud export/import round trip into a clean store with identity, content, session and project intact.
internal/cloud/cloudstore/dashboard_queries_test.go TestDashboardCountsPiSavedPromptUnderItsProject — a prompt delivered as an upsert mutation is counted on the project's dashboard row, listed in recent prompts, and resolvable through the sync_id the detail page uses; a neighbouring project does not see it.

🧪 Test Plan

  • Unit tests pass locally: go test ./... — 22 packages, all ok.
  • E2E tests pass locally: go test -tags e2e ./internal/server/...ok, including the new TestPiPromptPersistenceE2E.
  • Pi plugin suite passes locally: npm test in plugin/pi — 44 tests, 0 failures. The broad-suite hang noted on the first revision of this PR does not reproduce after merging main.
  • gofmt -l clean on every touched Go file; go build ./... and go vet ./... clean (including -tags e2e).
  • The new Pi test was verified to fail against the pre-fix index.ts, which returns { id: 213, status: "saved" } instead of { prompt_id: 213, status: "saved" } — it is a real regression guard, not a passing assertion.

💬 Notes for Reviewers

Review feedback was that the rename removed the response ambiguity but did not prove the dashboard and cloud persistence #706 asked about, and that the closure claim should wait for that evidence. That evidence is now in the PR, across three layers: the Pi tool's actual HTTP calls, the server's /prompts retrieval surfaces, and the sync/cloud/dashboard path including project scoping in both directions.

Worth stating plainly for the record: nothing in the persistence path turned out to be broken. Every new test passed on first run against unmodified production code. The only production change in this PR remains the one-line prompt_id rename. If the reporter's dashboard genuinely showed 0 prompts, this coverage says the cause was not the local save, the mutation scope, the round trip, or the dashboard query — the most likely remaining explanation is the intermittent HTTP transport errors the issue itself notes, where the POST /prompts never reached the server at all. That is a separate concern from #706's identity defect and is not addressed here.

Merge Risk: ⚪ Minimal · up to 7bc82

The PR only renames the successful save response field to prompt_id; persistence and project scoping remain unchanged and are covered by tests. One localized assertion could further strengthen the test against incorrect project re-scoping, but no merge-blocking production risk is established.

Requesting changes. Renaming the response field to prompt_id removes response ambiguity but does not prove the dashboard and cloud persistence required by #706. Keep #706 open until there is end-to-end Pi /prompts coverage and project-scoped sync proof. Update the closure claim only after that evidence exists.

Issue Gentleman-Programming#706 asked for evidence that a prompt saved through the Pi plugin is
actually persisted and retrievable, not just that the response names the right
identity namespace. The existing coverage asserted over the extension source
text, which cannot show a prompt ever left the process.

Add two executable layers instead:

- A Pi-native tool test that loads the extension, records the HTTP requests
  mem_save_prompt issues, and asserts the session is created under the
  requested project before the prompt is posted to /prompts with that same
  scope, and that the response echoes the server-assigned id as prompt_id.
- A Go e2e test that replays that exact wire sequence and reads the prompt back
  from /prompts/recent and /prompts/search under its own project, confirms the
  returned id resolves to the content just written, confirms it carries a
  sync_id, and confirms another project cannot see it.

The prompt id in Gentleman-Programming#706 was never stale: prompts are numbered from user_prompts,
a sequence independent of observations. The e2e test pins that by asserting the
same id read as an observation never answers with the prompt content.
Issue Gentleman-Programming#706 reported a prompt that saved locally while the cloud dashboard kept
showing 0 prompts for the project. Nothing covered the path between those two
facts, so the report could not be answered either way.

Add coverage for the two remaining hops:

- internal/sync: a prompt saved with the Pi wire shape enqueues an upsert
  mutation filed under its own project, keyed by its sync_id and carrying that
  project in the payload; the prompt then survives a cloud export/import round
  trip into a clean store with its sync_id, content, session and project
  intact, and does not widen into a neighbouring project.
- internal/cloud/cloudstore: a prompt delivered as an upsert mutation is
  counted on the project's dashboard row, listed in recent prompts, and
  resolvable through the sync_id the detail page is addressed by, while a
  neighbouring project does not see it.

Both paths already behaved correctly; they were untested, not broken.

Assert that the target project contains only its prompt.

The destination store starts empty. The test confirms that the target prompt arrives, but it does not reject a neighboring prompt that export or import incorrectly re-scopes to targetProject. The otherProject query still passes in that case.

Assert that pulled contains exactly one prompt before locating saved.SyncID.

Resolved. The prompt_id rename is now backed by the evidence #706 actually demanded, which is what was missing before: an end-to-end test proving a prompt saved through the Pi plugin reaches and is retrievable from /prompts, project-scoped sync coverage through the round trip, and the dashboard query path. The production delta is 3 lines; the rest is proof.

The merge with #734 kept both sides intact — the in-flight registration map and the no-normalization identity rule are untouched, and no .trim() was reintroduced on any runtime session ID path. The two near-duplicate module loaders in the test file were collapsed into one rather than left competing.

50/50 plugin tests, full Go suite and e2e green. Closes #706 now holds up.

Separately: while writing the sync proof, a real defect surfaced that is the opposite symptom of #706 — a prompt deleted locally never propagates its delete, because DeletePrompt hard-deletes the row so it cannot ride in chunk.Prompts, and materializedChunkMutations discards every non-relation chunk.Mutations entry. Observations escape it only because they soft-delete. Filed as #837 rather than widened into this PR.
