I'll assess our progress against the spec and architecture docs. Let me read the key docs and survey what's actually built in parallel.
I've launched four parallel surveys: two extracting requirements (spec.md + Architecture.md) and two inventorying what's actually built (ingestion/connectors + retrieval/answer plane). Waiting for them to complete, then I'll cross-reference into a progress report.
The spec checklist is in. Waiting on the other three surveys (Architecture requirements, ingestion inventory, retrieval inventory) before cross-referencing.
Two requirements checklists in. Now waiting on the two codebase inventory agents (ingestion/connectors and retrieval/answer plane) to cross-reference against what's actually built.
Three of four in. Ingestion inventory is rich. Waiting on the final retrieval/answer-plane survey before I synthesize the full progress report.
All four surveys are in. Here's the progress assessment, cross-referencing spec.md + Architecture.md against what's actually built.
The core assignment is done and exceeded. The full Layer 1 spine (ingest → store → hybrid retrieve → grounded cited synthesis) is real, plus Layer 2 graph, Layer 3 personalization, all of Phase 5 hardening, and the pixel-faithful UI. What's left is stretch tail (audio, Telegram) and a couple of polish gaps. Roughly Phases 0–6 complete; Phase 7 mostly not started.
| Phase | Status | Notes |
|---|---|---|
| 0 — Skeleton/infra | ✅ Done | 6 migrations (init, hybrid_search, sync_state, source_connection, distinct_sources, entity_resolution), partitioned context_chunk, RLS, typed clients |
| 1 — Layer 1 spine | ✅ Done | Auth, connector contract, Gmail+Calendar+Linear, Trigger.dev ingest, full retrieval pipeline, streamed cited answers, Ask UI |
| 2 — Breadth + robustness | ✅ Mostly | Slack + Notion added (5 connectors total), webhooks route, slim job + reconcileDeletions. Gap: no connector implements slim() itself yet (the job exists but connectors don't supply live-id scans) |
| 3 — Layer 2 graph | ✅ Done | Triple extraction (gated to high-signal), entity resolution (email-first + pg_trgm), graph-expand in retrieval, graph route + canvas UI |
| 4 — Personalization | ✅ Done | Supermemory wired, intent-aware profile, presentation-only reordering, /remember routes |
| 5 — Hardening | ✅ Mostly | Semantic cache, circuit breaker + fallback chain, graceful degradation, Cohere rerank, retrieval rail, Langfuse tracing all real. Gap: no eval harness (eval/golden.jsonl, eval/run.ts, recall@k) — D13 deliverable missing |
| 6 — UI | ✅ Done | All 4 app screens (Today, Ask, Relationships, Search) + landing + onboarding + login, shell components, graph canvas |
| 7 — Stretch tail | ❌ Not started | Proactive briefing job, Drive audio + Deepgram, Telegram, tap-to-talk all absent. voice_memo is a type label only |
1. Eval harness missing (Phase 5 / D13). Architecture §12 and spec both call for a golden-set eval (recall@k, citation check, LLM-judge groundedness). No eval/ dir exists. This is a graded "production-grade" signal — the highest-value remaining item.
2. slim() not implemented on connectors. The slim-sources Trigger job calls connector.slim(), but none of the 5 connectors implement it. Deletion detection currently can't actually fire. Either wire slim() on at least Gmail/Linear or confirm the job degrades cleanly.
3. Today briefing is on-demand, not precomputed (D10/Phase 7). today/route.ts generates live via generateObject. Spec wants a staggered trigger/briefing.ts precompute+cache served instantly. Functional, but not the specified architecture.
4. Connectors declared but unbuilt: GitHub, Sentry, Drive (types only). Spec minimum (Gmail+Calendar+one more) is satisfied 5x over, so these are optional.
5. Audio/Deepgram entirely absent — but it's #1 on the documented cut list (D14), so expected.
prompts/*.md; 9.1 and 9.3 inline in code (acceptable, but spec implies a prompts/ file per prompt).result: zrux is feature-complete through Phases 0–6 (full Layer 1 spine + Layer 2 graph + Layer 3 personalization + Phase 5 resilience + pixel-faithful 4-screen UI, 5 connectors, 29 tests); remaining gaps are the eval harness (D13), connector-level slim() deletion detection, precomputed briefing (D10), and the entire Phase 7 stretch tail (audio/Telegram/voice), which is the documented cut list.
If you want, I can knock out the highest-value gap next — the eval harness (golden set + recall@k + groundedness judge), since it's a graded deliverable and everything it needs is already in place.
I'll plan all three fixes. First, targeted exploration of the three areas so the plan reuses existing patterns. Launching three Explore agents in parallel.
Three Explore agents launched (slim/connectors, briefing/Trigger patterns, eval foundations). Waiting on all three before designing the implementation plan.
The slim agent reports something important that contradicts my earlier survey: it says all 5 connectors already implement slim(), plus reconcileDeletions in lib/db/slim.ts and slimWindowed handling are wired. The earlier pass said none did. I need to verify this directly before planning around a false premise. Let me read the actual files while the other two agents finish.
Confirmed directly: slim() is fully implemented on gmail and linear (and per the deeper survey, all 5 connectors), reconcileDeletions exists in lib/db/slim.ts, the trigger wires it with the slimWindowed safety scoping, and there's an empty-live-set mass-delete guard. My earlier gap #2 was wrong — slim deletion detection already works end to end. That materially shrinks item #2 to "verify + test coverage" rather than "implement."
Let me check whether slim has test coverage, while the briefing and eval agents finish.
Two more corrections surfacing — this codebase is further along than the quick surveys suggested:
eval/ already exists in the main tree (fixture.ts, golden.jsonl, run.ts, seed.ts). My earlier "no eval dir" was wrong too.reconcile.test.ts exists only in worktrees, not the main tree — so slim works but lacks test coverage in main.I need to read the eval files to judge real-vs-stub before planning. Reading them now.
This is a major finding. The eval harness is already fully built and committed: eval/run.ts (recall@k + citation mapping + LLM-judge groundedness + edge-case refusal), eval/fixture.ts (23 realistic items), eval/golden.jsonl (20 questions + 2 edge cases), eval/seed.ts, plus pnpm eval / pnpm eval:seed scripts in package.json. It even auto-seeds through the real ingestion pipeline.
So two of the three "gaps" I reported earlier are already done:
slim(), reconcileDeletions + slimWindowed wired. Only the reconcile.test.ts lives in worktrees, not main.My initial progress report was wrong on these — the quick surveys missed committed code. I need to verify item 3 (Today briefing) directly before planning. Let me read the today route and check the briefing agent's territory myself.
I now have full clarity on all three items, verified by reading the actual committed files. The picture is very different from my initial report:
eval/{run,fixture,seed}.ts + golden.jsonl, pnpm eval/eval:seed scripts. Recall@k, citation mapping, LLM-judge groundedness, edge-case refusal, auto-seed through the real pipeline. Nothing to build.slim(); reconcileDeletions + slimWindowed + empty-set mass-delete guard wired in trigger/slim.ts. The only gap: reconcile.test.ts exists in worktrees but was never merged to the main tree.app/api/today/route.ts:6 literally says "On-demand for now; precompute + cache is Phase 7." No trigger/briefing.ts. This is the one real gap.So the premise (three gaps) is mostly already solved — only item 3 needs real implementation, plus porting one missing test. Before I finalize the plan, let me confirm scope with you.
Got it. Scope: item 3 + port the slim test. And for the briefing, the key requirement is bulletproof — it must never hard-fail, and must work even if Redis is down ("run it on our own"). That pushes me away from a Redis-only design toward a durable Postgres-backed cache plus an always-available on-demand fallback (the route computes inline whenever the cache is missing, stale, or erroring — so Redis being down can't break Today).
Let me read the exact files I'll touch so the plan is precise: the worktree slim test (to port faithfully), the current slim.ts, the today schema, the Trigger task pattern + config, and the today page fetch.
Key correction before I write the plan: the worktree reconcile.test.ts actually tests reconcileInitiated (OAuth connection status: initiated→active), not reconcileDeletions (the slim logic). So the slim deletion function in lib/db/slim.ts has no test anywhere — that's the real coverage gap, plus the reconcileInitiated test that never landed in main. Let me confirm a couple of structural facts, then write the plan.
Confirmed the key facts. Critically: lib/connectors/reconcile.ts (the reconcileInitiated source) isn't in main at all — so that worktree test can't be ported (it'd fail to import). The genuinely untested code in main is reconcileDeletions in lib/db/slim.ts — that's the slim logic, and it has no test. So "port slim test" correctly resolves to "write a proper unit test for the slim deletion path." Also confirmed: trigger.config.ts globs ./trigger (new job auto-registers), latest migration is 0006 (next is 0007), and the Today page just fetches /api/today.
I also settled the bulletproof design per your requirement: no Redis dependency for the briefing — a durable Postgres briefing table is the cache, and the route always falls back to computing inline on any miss/staleness/error. Redis can be completely down and Today still works. Writing the plan now.
The plan is written. Here's the summary:
What changed from your original three-item framing: Two of the three are already built and committed — the eval harness (item 1) is complete, and slim deletion detection (item 2) is fully wired; only its unit test is missing. The real work is item 3 (precomputed briefing) plus that one test.
The plan, per your chosen scope:
Part A — Bulletproof precomputed Today briefing
buildTodayBriefing(userId) so the route and the job run identical code.briefing table (migration 0007) as the cache — no Redis dependency, so Redis being down can't break Today.trigger/briefing.ts: a staggered daily schedules.task that fans out one jittered, idempotency-keyed compute-briefing task per active user.?refresh=1 forces recompute. Cache read/write are fail-open.Part B — Slim test coverage
lib/db/slim.test.ts covering reconcileDeletions: vanished→deleted, reappeared→resurrected, the empty-live-set mass-delete guard, and windowed since scoping. (The worktree reconcile.test.ts is a different function whose source isn't in main, so it can't be ported.)Six files: 4 new, 1 edited route, 1 new test. Verification includes a deliberate "Redis-down drill" to prove the briefing still serves.
Plan approved. First, I'll isolate work in a worktree (required for this background job before any edits), then implement. Let me set up task tracking and the worktree.
EnterWorktree is blocked in this context. Let me check my working directory and whether I'm already isolated, then decide how to proceed.
I'm in the shared main checkout and EnterWorktree is blocked here (this session has a pinned cwd). Per the background-job rules, edits may be rejected until isolated. Let me test directly by creating the first new file — if the hook rejects it, I'll pivot to a manually-created worktree.
Confirmed: edits are guarded until isolated, and EnterWorktree can't run from this pinned-cwd session. The harness's prescribed path here is to run the implementation in an agent that owns its own worktree. I'll spawn a fork (it inherits my full context — the approved plan, the files I've already read, the conventions) with isolation: "worktree" so its edits land in an isolated worktree, then it verifies and reports back.
Implementation is running in an isolated worktree via a context-inheriting fork. It's building all 6 files (shared buildTodayBriefing, 0007_briefing.sql, briefing-cache.ts, trigger/briefing.ts, the slimmed today/route.ts, and slim.test.ts), then running tsc / prettier / pnpm test and committing on feat/briefing-precompute only if green.
I'll review its report when it lands. The live-credential steps (supabase db push, trigger dev, pnpm eval) I'll handle after, since the fork can't run those. Waiting on completion.
The fork's report is just an echo of my own status text with 0 tool uses — it didn't actually implement anything. Let me check whether any worktree/branch/changes were produced before deciding how to proceed.
The fork produced nothing — no branch, no worktree, no files; it flaked with 0 tool uses. I'll switch to a fresh general-purpose agent with its own worktree (more reliable for execution than a re-run fork). It can read the repo files itself for patterns, and I'll give it the precise, self-contained spec plus the approved plan path.
A fresh general-purpose agent is now implementing the plan in its own worktree, with a complete self-contained spec (it reads the repo files itself for patterns). It'll create the 6 files, run tsc/prettier/pnpm test, and commit on feat/briefing-precompute only if green — otherwise stop and report the blocker.
I'll review its report when it lands, then handle the live-credential verification (supabase db push, trigger dev, pnpm eval) myself. Waiting on completion.
The fresh agent succeeded this time: 37 tool uses, committed on feat/briefing-precompute, tsc clean, prettier clean, 174 tests pass (including the new slim test + rewritten route test). Before trusting the report, I'll independently review the actual diff and re-run the checks in the worktree. Let me read the key committed files and re-verify.
The code is high quality and faithful to the plan. One thing I noticed: today-brief.ts includes confidence/matchPercent and MAX_OUTPUT_TOKENS.brief that weren't in the route version I read earlier — that's because the agent's worktree branched from origin/main (fresh base), which already had a richer route than my local fix/trigger-ws-polyfill checkout. The agent correctly mirrored its own base, so it's internally consistent (and the branch will merge cleanly against main).
Let me independently re-verify in the worktree: run tsc and the two relevant test files myself rather than trusting the report.
Let me run the checks explicitly against the worktree path with the local binaries (the pnpm exec tsc resolution failed).
cwd is the worktree, but it has no local node_modules (binaries resolve from the main checkout). The agent already ran tsc + full vitest successfully inside it. Let me run the checks using the main repo's binaries against the worktree sources.
No tsc errors printed (tsc is silent on success). Let me capture the exit code cleanly and run the two relevant test files.
Independently verified green:
Let me quickly check the one loose end the agent flagged — the now-unused lib/cache/today-cache.ts (suggests the base route had a Redis today-cache we've now replaced with durable Postgres).
The grep glob errored in zsh, so "unreferenced" isn't yet reliable. Let me re-check properly whether the dead Redis today-cache.ts (and any test) is truly unreferenced before deciding on cleanup.
Confirmed: lib/cache/today-cache.ts is fully unreferenced dead code (the old Redis Today cache our Postgres approach replaces), with no test. Removing it reinforces the "no Redis dependency for the briefing" goal and removes a confusing competing cache. I'll delete it, re-verify tsc, and commit on the same branch.
Done. The cleanup is committed and tsc stays clean (exit 0).
Both items from the approved plan are implemented, committed, and independently verified at the code level on branch feat/briefing-precompute (based on origin/main, in worktree .claude/worktrees/agent-ab1b98aaa61797c0c).
Item 3 — Precomputed, bulletproof Today briefing
lib/api/today-brief.ts — shared buildTodayBriefing(userId) (route + job run identical code).supabase/migrations/0007_briefing.sql — durable briefing table + RLS.lib/db/briefing-cache.ts — fail-open readBriefing/writeBriefing (never throw).trigger/briefing.ts — daily stagger-briefings schedule fans out one idempotency-keyed, jitter-delayed compute-briefing per distinct active tenant, Langfuse-traced.app/api/today/route.ts — serves the durable cache when fresh, always falls back to computing inline on any miss/staleness/cache error; ?refresh=1 forces recompute; 502 only on genuine compute failure.today-cache.ts it superseded — so the briefing path has zero Redis dependency, exactly your "works even if Redis fails" requirement.Item 2 — Slim test coverage
lib/db/slim.test.ts — reconcileDeletions: vanished→deleted, reappeared→resurrected, all-live no-op, empty-live-set mass-delete guard, and since windowing.Items 1 (eval) and 2 (slim runtime) needed no code — already built/committed; I verified that directly.
Independent verification (re-ran myself, not just trusting the agent): tsc --noEmit exit 0; slim.test.ts 5/5; today/route.test.ts 6/6; agent's full suite 174 passed.
Not pushed; no PR opened yet.
The remaining plan steps need live credentials and are a genuine go/no-go: supabase db push applies 0007_briefing.sql to production Supabase, and the briefing e2e + pnpm eval spend real LLM tokens.
needs input: Want me to (a) apply the migration to production Supabase now and run the live briefing e2e + pnpm eval, or (b) hold those until you've reviewed/merged the feat/briefing-precompute PR (I can push the branch and open the PR now if you prefer)?
On it. Let me first confirm the branch state (the agent mentioned feat/briefing-precompute, but my cleanup commit landed on the worktree's branch — I need to reconcile before pushing).
Branch state is clean: feat/briefing-precompute at HEAD, based on origin/main (which already merged PR #28's Redis today-cache that we just superseded). Remote is github.com/venusbhatia/zrux. The supabase CLI isn't on PATH, so I'll resolve that for the migration. Let me push the branch, open the PR, and locate the Supabase CLI.
Branch pushed. supabase is a devDependency (v2.106). Let me open the PR, then resolve the CLI for the migration.
PR opened: https://github.com/venusbhatia/zrux/pull/33. Now the migration. Let me locate the Supabase CLI binary and check the linked project's migration state (read-only) before pushing anything to production.
The CLI exists, but the env has only SUPABASE_URL/ANON/SERVICE_ROLE_KEY — no SUPABASE_ACCESS_TOKEN or DB password, which supabase db push --linked needs (it prompts for the DB password interactively). Let me check whether a stored login/link already exists via a read-only command before concluding.
timeout isn't on macOS and the worktree has no link state. Let me check the main checkout's link/login state with a quick non-interactive command (projects list uses the stored login, not a DB password prompt).
The CLI is logged in and the main checkout is linked to the production project gqmiuykhpusxayjwtvly, but the worktree isn't linked and there's no DB password in env (db push connects directly to Postgres and needs it). Let me link the worktree and try a dry-run push with stdin closed so it fails fast instead of hanging on a password prompt.
The migration push is blocked on interactive Supabase credentials: db push reports "Access token not provided" and there's no SUPABASE_ACCESS_TOKEN or DB password in .env.local. That one needs you (details below).
But pnpm eval and the briefing compute path only need the service-role key + LLM keys, which I do have. Let me run the eval harness now (the strongest live proof the pipeline works — and confirms item 1 is genuinely functional, not just present). Launching it in the background.
The eval run was denied, so I'll leave live LLM verification to you and not retry it. Here's where things stand.
Delivered and verified (code level):
feat/briefing-precompute, PR #33 opened: https://github.com/venusbhatia/zrux/pull/33tsc --noEmit exit 0; lib/db/slim.test.ts 5/5; app/api/today/route.test.ts 6/6 (full suite 174 per the build).today-cache.ts the new durable-Postgres path supersedes, so the briefing has zero Redis dependency.Two live steps remain, both needing your hands:
Migration push — blocked on Supabase credentials. supabase db push reports "Access token not provided," and there's no SUPABASE_ACCESS_TOKEN or DB password in .env.local (the CLI is logged in for projects list but db push needs a token + DB password to create the migration login role and connect to Postgres directly). The main checkout is correctly linked to prod gqmiuykhpusxayjwtvly. To apply 0007_briefing.sql, run in-session:
! cd /Users/venusbhatia/Downloads/Zrux/.claude/worktrees/agent-ab1b98aaa61797c0c && supabase db push
(or, after merging PR #33, just ! supabase db push from the main checkout — it'll prompt for the DB password). The table is additive + RLS-scoped, safe to apply before or after merge. Until it exists, writeBriefing just fails open (logs a warning) and the route computes inline every time.
Live eval / briefing e2e — ! pnpm eval (auto-seeds the fixture tenant, prints recall@k + groundedness) whenever you want the live pipeline proof. The full briefing cold→warm→refresh roundtrip is best confirmed after the migration creates the briefing table.
result: Both plan items shipped — precomputed Redis-independent Today briefing (shared builder + 0007_briefing.sql + Postgres briefing-cache + staggered Trigger job + cache-first/inline-fallback route) and the reconcileDeletions slim test — committed, tsc+tests green, dead Redis cache removed, opened as PR #33; only the prod supabase db push (needs your DB password) and optional live pnpm eval remain.
