+# Add full-chain (100k block) import stats to the perf graph
+
+## Goal
+
+Show the picofuzz **full-chain** (100k-block) import stats on the performance
+stats page (`perf-graph/`, deployed to GitHub Pages as "typeberry import
+stats"), alongside the existing per-scenario charts (`conformance`, `fallback`,
+`safrole`, `storage`, `storage_light`).
+
+## Context
+
+- The perf page renders one `<Chart>` per scenario. Each chart loads a CSV from
+  `perf-graph/public/<name>.csv` with the 20-field stats format
+  (`projectName,date,count,sum,mean,median,min,max,range,stdDeviation,variance,p1,p5,p10,p25,p50,p75,p90,p95,p99`).
+- The **Picofuzz Full Chain** workflow (`.github/workflows/picofuzz-full.yml` →
+  `tests/picofuzz/full_chain.test.ts`) already emits `full_chain.csv` in exactly
+  this format, uploaded as artifact `picofuzz-csv-full_chain`. Each run chains
+  the previous run's CSV, so the latest artifact holds the full accumulated
+  history (~10 rows as of 2026-07-13, versions v0.9.x–v0.11.x, `count=100051`).
+- The deploy (`deploy-perf-graph.yml`) is triggered by the **Picofuzz Tests**
+  workflow and downloads `picofuzz-csv-*` artifacts *from that triggering run
+  only*. The full-chain artifact lives in a **different** workflow's runs, so it
+  is not currently picked up.
+
+## Design
+
+### 1. Frontend (`perf-graph/`)
+- Add an optional `title?: string` prop to `Chart` so the heading can read
+  "Full chain import (100k blocks)" instead of the raw `name`. Existing charts
+  fall back to `name` (unchanged behaviour).
+- Render a dedicated `<Chart name="full_chain" title="..." />` in its own
+  section in `App.tsx` (mirroring the `conformance-section`), conceptually
+  separate from the per-scenario fuzzers.
+- No changes to data parsing or the global version filter — `full_chain` shares
+  the `v0.x.x` version namespace and plugs into the existing filter as-is.
+
+### 2. Deploy wiring (`deploy-perf-graph.yml`)
+- Add a step that resolves the latest **successful** "Picofuzz Full Chain" run
+  via the GitHub API and downloads its `picofuzz-csv-full_chain` artifact into
+  `./csv-artifacts/` (`continue-on-error`, mirroring the existing download).
+  `merge-csvs.ts` globs whatever CSVs exist, so `full_chain.csv` is merged with
+  no merge-script change.
+- Add "Picofuzz Full Chain" to the `workflow_run.workflows` trigger list so a
+  fresh full-chain result redeploys the page the same day. (Deploy runs on
+  `ubuntu-latest`, not the shared self-hosted runner — no runner contention.)
+
+### 3. Seed data
+- Commit the current 10-row history as `perf-graph/public/full_chain.csv`,
+  consistent with the already-committed `fallback.csv` etc. The artifact has
+  90-day retention, so the repo copy is the long-term history base that merge
+  builds on.
+
+## Testing
+- `npm run build` in `perf-graph/` with the seeded CSV → confirms the chart
+  parses and renders.
+- Run `merge-csvs.ts` against a `csv-artifacts/full_chain.csv` → confirms merge
+  picks it up and dedups by `(version,date)`.
+- The API-fetch workflow step is validated on CI; it is a mirror of the existing
+  working `download-artifact` step.
+
+## Out of scope
+- The `docker-imports-full` wall-clock flow (a separate, larger project that
+  would require inventing a new metric and chart type).
