Bohan Jiang	f628e48775	refactor(server): error-returning ParseUUID to prevent silent data loss ... * refactor(server): make ParseUUID error-returning to prevent silent data loss (MUL-1410) util.ParseUUID previously swallowed errors and returned a zero pgtype.UUID on invalid input. When this zero UUID reached a write query (DELETE/UPDATE), the SQL matched zero rows and the handler returned 2xx success — producing silent data corruption. #1661 (DeleteIssue with identifier-style ID) was the visible symptom; PR #1680 patched that one site, this commit closes the class of bug. Changes: - util.ParseUUID now returns (pgtype.UUID, error). Add util.MustParseUUID for trusted round-trips that should panic on invalid input. - handler/handler.go: parseUUID wrapper now calls MustParseUUID — any unguarded user-input string reaching it surfaces as a recovered panic (chi middleware.Recoverer → 500) instead of silently corrupting data. Add parseUUIDOrBadRequest(w, s, fieldName) for handler entry points. - Convert every Queries.Delete*/Update* call site reachable from raw user input (autopilot, comment, project, skill, skill_file, label, pin, attachment, feedback, issue assignee, daemon runtime, workspace) to validate UUIDs explicitly with parseUUIDOrBadRequest, returning 400 on invalid input. Where a resolved entity.ID is already in scope, write queries now use it directly instead of re-parsing the URL string. - Update getWorkspaceMember + loadIssueForUser to handle invalid UUIDs gracefully (404/400 instead of panic). - Update util/middleware/cmd-level callers (subscriber_listeners, notification_listeners, activity_listeners, scope_authorizer, middleware/workspace) to use the error-returning API. - Add server/internal/util/pgx_test.go covering valid/invalid input and the MustParseUUID panic contract. - Add TestDeleteIssueByIdentifier + TestDeleteIssueRejectsInvalidUUID regression tests in handler_test.go (the original #1661 bug + the invalid-input case). - Document the handler UUID parsing convention in CLAUDE.md so the rule is enforceable in future PR review. * fix(server): address GPT-Boy review of #1748 P1 fixes from PR #1748 review: 1. Migrate remaining request-boundary UUIDs to parseUUIDOrBadRequest so malformed input returns 400 instead of panic/500. Was missing on: - issue.go: workspace_id in CreateIssue/ChildIssueProgress/ListIssues/ SearchIssues/BatchUpdateIssues/BatchDeleteIssues; project_id / parent_issue_id / lead_id / assignee_id / assignee_ids / creator_id filters; batch issue_ids and assignee/parent/project fields in BatchUpdateIssues (skip on bad input via util.ParseUUID, matching the existing per-row continue semantics). - project.go: project id + workspace_id in GetProject/UpdateProject/ DeleteProject; lead_id in CreateProject/UpdateProject; workspace_id in ListProjects + SearchProjects. - handler.go: resolveActor now uses util.ParseUUID for X-Agent-ID / X-Task-ID headers; invalid UUID falls back to "member" (matches pre-existing semantics) instead of panicking. - issue.go: validateAssigneePair returns 400 on invalid workspace_id instead of panicking. 2. Fix issue:deleted WS event payloads to emit uuidToString(issue.ID) instead of the raw URL string. After an identifier-path delete ("MUL-7"), the previous payload would have leaked the identifier to subscribers, leaving stale entries in frontend caches that key by UUID. Updated DeleteIssue (issue.go:1341) and BatchDeleteIssues (issue.go:1641). The slog "issue deleted" log line also now records the resolved UUID so logs match the WS payload. 3. Extend TestDeleteIssueByIdentifier to subscribe to the bus and assert issue:deleted.payload.issue_id is the resolved UUID, not the identifier. * fix(server): validate remaining reviewed UUID inputs * fix(server): validate remaining handler UUID inputs * fix(server): finish request boundary UUID audit * fix(server): validate remaining request body UUIDs * fix(server): validate runtime path UUIDs * fix(server): validate remaining audit UUID inputs --------- Co-authored-by: Eve <eve@multica.ai>	2026-04-28 14:50:28 +08:00
devv-eve	637bdc8eb3	feat(analytics): full PostHog pipeline + 6 funnel events (MUL-1122) (#1367) ... * feat(analytics): add PostHog client with async batch shipping Introduces server/internal/analytics, the shipping layer for the product funnel defined in docs/analytics.md. Capture is non-blocking — events are enqueued into a bounded channel and a background worker batches them to PostHog's /batch/ endpoint. A broken backend drops events rather than blocking request handlers. Local dev and self-hosted instances run a noop client until the operator sets POSTHOG_API_KEY. This is PR 1 of MUL-1122; signup and workspace_created emission land in the follow-up commit so this change is independently reviewable. * feat(server): emit signup and workspace_created analytics events Wires analytics.Client through handler.New and main, then emits the first two funnel events: - signup fires from findOrCreateUser (which now reports isNew), covering both the verification-code and Google OAuth entry points — a single emission site guarantees Google signups aren't missed. - workspace_created fires after the CreateWorkspace transaction commits, with is_first_workspace computed from a post-commit ListWorkspaces count so we can distinguish fresh-user activation from returning-user expansion. Tests use analytics.NoopClient so nothing ships from test runs. PR 1 of MUL-1122; runtime_registered and issue_executed follow in later PRs per the plan. * refactor(analytics): drop is_first_workspace from workspace_created Stamping "is this the user's first workspace?" at emit time races under concurrent CreateWorkspace requests: two transactions committing close together can both read a post-commit count greater than one and both emit false. Fixing it at the SQL layer requires a schema change we don't want in PR 1. PostHog answers the same question exactly from the event stream (funnel on "first time user does X" / cohort on $initial_event), so removing the property loses no information and makes the emit side race-free. * docs(analytics): document self-host safety defaults Spell out why self-hosted instances never ship events upstream by default (empty POSTHOG_API_KEY → noop client) and explain how operators can point at their own PostHog project without any code change. * feat(analytics): emit runtime_registered, issue_executed, team_invite_* Three server-side funnel events, all gated on first-time state transitions so retries and re-runs don't inflate the WAW buckets: - runtime_registered fires from DaemonRegister when UpsertAgentRuntime reports (xmax = 0) — i.e. the row was inserted, not updated. Heartbeats and re-registrations stay silent. - issue_executed fires from CompleteTask after an atomic UPDATE issue SET first_executed_at = now() WHERE id = $1 AND first_executed_at IS NULL flips the column for the first time. Retries, re-assignments, and comment-triggered follow-up tasks hit the WHERE clause and no-op. Carries nth_issue_for_workspace so the ≥1/≥2/≥5/≥10 buckets filter without extra queries. - team_invite_sent fires from CreateInvitation and team_invite_accepted from AcceptInvitation, closing the expansion funnel. Adds a 050 migration for issue.first_executed_at plus a partial index so the workspace-scoped executed-count query doesn't scan the never-executed tail. * feat(config): surface PostHog key via /api/config Extends AppConfig with posthog_key / posthog_host sourced from env on every request (so operators can rotate the key via secret refresh without a restart). Reading the key off the server — rather than baking it into the frontend bundle via NEXT_PUBLIC_* — means self-hosted instances inherit the blank key automatically and never ship events upstream. * feat(analytics): wire posthog-js identify + UTM capture on the client Adds @multica/core/analytics — a thin wrapper around posthog-js that owns attribution capture and identity merge. Posthog-js config comes from /api/config (not NEXT_PUBLIC_*), so self-hosted instances whose server returns an empty key automatically run the SDK inert. captureSignupSource stamps a multica_signup_source cookie with UTM params and the referrer's origin (never the full referrer — that can leak OAuth code/state in the callback URL). The backend signup event reads this cookie on new-user creation. Identity flows: - auth-initializer fires identify() right after getMe() resolves, on both cookie and token paths. A getConfig/getMe race is handled by buffering a pending identify inside the analytics module and flushing it once initAnalytics finishes. - auth store calls identify() on verifyCode / loginWithGoogle / loginWithToken and resetAnalytics() on logout so the next login merges cleanly without bleeding events. * docs(analytics): describe runtime_registered, issue_executed, invite events Fills in the schema for the remaining funnel events. Captures the design commentary that belongs next to the contract rather than in a PR description — in particular why issue_executed uses the atomic first_executed_at flip instead of counting task-terminal events, and why runtime_registered relies on xmax = 0 rather than a query-then-write. * fix(analytics): drop non-atomic nth_issue_for_workspace from issue_executed Computing the workspace's Nth-issue ordinal at emit time is not atomic under concurrent first-completions — two transactions can both run MarkIssueFirstExecuted, then both run CountExecutedIssuesInWorkspace, and both observe count=1 before either has committed, so both events go out stamped as n=1. Serialising it would mean a per-workspace advisory lock or a SERIALIZABLE-isolated tx; PostHog answers the same question exactly at query time via row_number() partitioned by workspace_id, so the emit-time property adds risk without adding information. Removes the property from analytics.IssueExecuted, deletes the unused CountExecutedIssuesInWorkspace query, and regenerates sqlc. The partial index stays — any future workspace-scoped executed-issue query will want it. * fix(analytics): wire $pageview and harden signup_source cookie payload Two frontend fixes from the PR review: - PageviewTracker, mounted under WebProviders, fires capturePageview on every Next.js App Router path / query-string change. Without this the capturePageview helper in @multica/core/analytics was never called and the acquisition funnel's / → signup step was empty. - captureSignupSource now caps each UTM / referrer value at 96 chars *before* JSON.stringify, and drops the whole cookie when the serialised payload still exceeds 512 chars. Previously the overall slice(0, 256) could leave a half-JSON string on the wire that neither the backend nor PostHog could parse. Both capturePageview and identify now buffer a single pending call when fired before initAnalytics resolves — otherwise the initial "/" pageview and same-turn login identify race the /api/config fetch and get dropped. resetAnalytics clears both buffers so a logout→login cycle stays clean. * fix(analytics): URL-decode signup_source cookie on read Go does not URL-decode Cookie.Value automatically, so the frontend's JSON-then-encodeURIComponent payload was landing in PostHog as percent-encoded garbage (%7B%22utm_source...). Unescape on read so the backend receives the original JSON string the frontend intended, and drop values that fail to decode or exceed the server-side cap — sending truncated garbage is worse than sending nothing. Oversized-cookie guard matches the frontend's SIGNUP_SOURCE_MAX_LEN. * docs(analytics): reflect nth-issue drop, $pageview wiring, cookie encoding Pulls the schema doc back in line with the code: issue_executed no longer advertises nth_issue_for_workspace (with a note about why PostHog derives it at query time instead), the frontend $pageview section names the actual PageviewTracker component that fires it, and the signup_source section documents the per-value cap / overall drop rule and the encode-on-write / decode-on-read contract. --------- Co-authored-by: Jiang Bohan <bhjiang@outlook.com>	2026-04-21 14:42:52 +08:00
Bohan Jiang	60c5848794	feat(invitation): dedicated /invite/{id} page for accepting invitations (#1023) ... The email CTA now deep-links to /invite/{id} instead of the generic app URL. If the user isn't logged in, they're redirected to login with a ?next= param that brings them back to the invite page. Changes: - Backend: GET /api/invitations/{id} endpoint (enriched with workspace/inviter names) - Backend: Email template now links to /invite/{invitationId} - Frontend: Shared InvitePage component (packages/views/invite/) - Frontend: Web route at (auth)/invite/[id], Desktop route at invite/:id - Frontend: /invite/ excluded from navigation history persistence	2026-04-15 00:37:53 +08:00
Bohan Jiang	1163f684fb	feat(invitation): send email notification when inviting a user (#1021) ... Uses the existing Resend email service to notify invitees. Email includes inviter name, workspace name, and a link to the app. Sent fire-and-forget in a goroutine to avoid blocking the API response.	2026-04-15 00:17:21 +08:00
Bohan Jiang	ff1d348274	feat(security): invitation acceptance flow for workspace members (#1019) ... * feat(security): replace instant member-add with invitation acceptance flow Users invited to a workspace must now explicitly accept the invitation before becoming a member. This fixes the security vulnerability where knowing someone's email was enough to auto-register their runtime to your workspace. Changes: - Add workspace_invitation table with pending/accepted/declined/expired states - Replace CreateMember with CreateInvitation (same endpoint, new behavior) - Add accept/decline/revoke/list invitation API endpoints - Add invitation WS events for real-time notification - Frontend: invitation accept/decline UI in workspace switcher - Frontend: pending invitations section in members settings tab * fix(invitation): address PR review nits - Fix invitation:revoked listener to send event to invitee user (was no-op) - Remove duplicate queryClient2 in app-sidebar.tsx, reuse existing queryClient - Add expires_at > now() filter to ListPendingInvitationsByWorkspace query	2026-04-15 00:01:18 +08:00
