THE HEADLINE

+

Edge absorbs the reads

+

Nearly every reader is served by Cloudflare's edge cache. The Astro origin only wakes on a cold slug or a revalidation.

+
+
+

Content lives in the repo

+
  • Posts are MDX files
  • Checked in, reviewed in PRs
  • No runtime database
+
+
+

CMS holds the big stuff

+

Images, OG art, and downloadable assets live in a separate bucket keyed by slug. Astro links them at render time.

RECORD SPRINT

+

Sprint 5 · 110 points

+

No mid-sprint additions, zero carry-over from S4, and the team's highest-complexity stories were completed two days early. The bar is not the goal — the conditions are.

+
+
+

Trend: rising with one dip

+

Average across 8 sprints: 89 points. S4 dipped to 78 — a dependency on an external API that shipped late. Excluding S4, the underlying trajectory is +4 pts/sprint.

+
+
+

What the chart doesn't show

+

Story points measure scope delivered, not value shipped. S3 at 95 points included three stories that were deprioritised before the sprint ended — they don't appear in the count.

The median hides the tail

+

A hundred and thirty-eight per-request latency samples for one checkout endpoint, one dot per request on a shared linear axis from zero. The median sits near 105 ms and looks perfectly healthy; the story is the three requests past 380 ms, because the p99 is what a customer at the wrong moment actually experiences.

The tail is the story

+

Read the swarm, not the middle

+

req-4c1f took 431 ms — four times the median — and it is one of three requests past 380 ms in a five-minute window. At this rate, roughly one checkout in fifty gets a visibly slow page, which is exactly the reading a single averaged number would have hidden.

+
+
+

Every unit keeps its mark

+

One dot = one request

+

No binning, no averaging: each request is its own dot at its exact value. Density reads as thickness — the swarm bulges where requests crowd — so the shape of the distribution and its outliers arrive in one glance.

+
+
+

The vertical axis says nothing

+

Packing, not a value

+

Dots dodge up and down only so they do not overlap; the offset is greedy packing at a fixed pitch and carries no meaning. A dot is never moved along the value axis to make room — crowding is data.

The biggest risk is not the slowest service

+

Nine services by p95 latency and error rate, bubble area proportional to requests per second, both axes from zero. Reports is the slowest thing on the board and barely matters; Payments runs near-peak traffic at the highest error rate, and that is where the incident will come from.

FOCAL · PAYMENTS

+

Payments burns the error budget fastest

+

2.8% of 760 requests per second — the highest error rate on the board applied to nearly the biggest volume. The accent marks the risk, not the worst number in any one column: Reports has worse latency and Gateway has more traffic, but neither multiplies out to as many failing requests.

+
+
+

Gateway shows where mass should sit

+

The largest bubble sits in the bottom-left corner — 900 requests per second at 85ms and half a percent of errors. Area is what keeps that reading honest: 900 is fifteen times Reports' 60, and the bubble carries fifteen times the ink. Radius-proportional sizing would square that into a 225-to-one blot.

+
+
+

Reports is slow and it does not matter

+

460ms p95 — the worst latency here — on 60 requests per second. The x-position raises the alarm and the tiny area answers it. Cropping the size encoding out of this chart turns Reports into the headline; that is the lie of every latency-only ranking.

The default everyone stopped choosing

+

Six internal packages ranked by weekly downloads, quarter by quarter. legacy-http entered the year in first place and left it in last; fetch-kit took the top rank in Q2 and never gave it back. Position is the only encoding — the vertical axis is rank, not volume.

FOCAL · LEGACY-HTTP

+

First to sixth in four quarters, and never a sudden drop

+

One rank, then two more, then two more. No single quarter looks alarming, which is exactly how a default dies — each straight segment joins two measured ranks and says nothing about the weeks between, so the chart claims the decline happened, not when in each quarter it happened.

+
+
+

fetch-kit took first place in Q2 and the line goes flat

+

A flat line at rank one is the strongest claim a bump chart makes: nothing displaced it for three consecutive snapshots. Note what it does not say — downloads could have doubled or halved in that time. Rank hides magnitude; that trade is the price of reading position at a glance.

+
+
+

schema-gen moved one rank and that is the whole story

+

Three flat quarters, then a single step up — inherited from legacy-http falling past it, not from growth of its own. A bump chart cannot tell those apart, which is why the footnote names the ranking key: the reader who needs magnitude follows the measure, not the picture.

THE HANDOFF

+

Raw becomes analysis-ready

+

The focal handoff marks the moment stored records become a trusted table owned by data science.

+
+
+

Roles stay explicit

+
  • Data Engineer ingests and lands
  • Data Scientist transforms and models
  • Analyst publishes the dashboard
+
+
+

Payloads explain change

+

Left and right chips show the input and output type at every active pipeline step.

FOCAL · STORAGE

+

MinIO — data lake core

+

S3-compatible object storage. Every tool in the stack either lands data here or reads from it. All formats land as raw files; Iceberg table metadata sits alongside them. When in doubt, write to MinIO.

+
+
+

Ingest — NiFi + Airflow

+
    +
  • NiFi: real-time routing, record-level transformation, CDC fan-out
    • +
  • Airflow: batch scheduling, cross-system DAGs, retry semantics
    • +
  • Two tools, two tempos — they complement rather than replace each other
    • +
+
+
+

Query — Trino + StarRocks

+
    +
  • Trino: federated ad-hoc SQL across any file format, any catalog
    • +
  • StarRocks: sub-second MPP for hot partitions and dashboard queries
    • +
  • Different latency budgets, same underlying lake
    • +
+
+
+

Consume

+

Superset for dashboards, JupyterLab for exploration, Python for batch ML. All three can write processed results back to MinIO via the dashed write-back path.

THE DESTRUCTIVE EDGE

+

Deleting an order cascades

+

`order_items.order_id` is the one `ON DELETE CASCADE` in this schema — remove an order and its line items go with it. Every other foreign key is `RESTRICT`.

+
+
+

Column to column, not box to box

+
  • Every FK anchors to a specific row on both ends
  • Fixed 24px row height keeps anchors predictable
  • The `ON DELETE` label is the point of the edge
+
+
+

Scoped to the subsystem

+

`products` truncates to a `+ 3 more columns` row rather than dumping every column. This is checkout, not a `\d+` of the whole database.

Nine packages, ranked by dependency depth. A tree can't show what matters here — that shared-types has four dependents, or that utils depends back on it. Coral is spent on exactly that cycle.

THE HEADLINE

+

One cycle, spent deliberately

+

Coral appears exactly twice: the dashed back-edge from utils into shared-types, and its CYCLE label. Everything else — including the four-dependent fan-in on shared-types — stays ink and muted, because only the cycle is the editorial point.

+
+
+

Why not a tree

+
  • shared-types has four parents, not one
  • utils depends back on its own ancestor
  • a tree can render neither honestly
+
+
+

Read the badges

+

The small N IN chip on every node is the fan-in count. It's the fastest way to spot where a change ripples widest before reading a single arrow.

Checkout service, production

+

Edge caching absorbs the reads, three ingress-fronted API pods handle the writes, and a single Postgres primary streams WAL to a standby in the data zone.

+
+

THE HEADLINE

+

One primary, one point of failure

+

Every write lands on `rds-primary`. The standby streams WAL continuously but isn't hot — a primary failure is the one scenario this topology hasn't automated away yet.

+
+
+

Three replicas behind one ingress

+
  • `checkout-api` runs 3 pod replicas
  • `sidecar-otel` ships traces from the same pod
  • nginx-ingress fans requests across all three
+
+
+

Edge absorbs static reads

+

Cloudflare's edge cache serves cached responses directly; only cache misses and writes reach the ingress zone.

Generic data platform integration topology

+

Three source patterns land in shared object storage, a query surface serves three consumer modes, and platform-wide services remain visibly cross-cutting.

+

+
+

THE HEADLINE

Storage and query are the platform core

The two focal surfaces separate durable ingestion from governed access without hiding the wire protocols.

+

Every integration stays explicit

  • CRM arrives over REST
  • Point-of-sale data arrives as CSV
  • Consumers use JDBC, kernels, or HTTPS
+

Services apply to the whole layer

Identity and centralized logging terminate at the platform boundary, not at an individual component.

Data platform access matrix

A compact policy view for five human roles across storage, query, analysis, reporting, and orchestration. Each intersection resolves to one explicit permission level.

+

THE HEADLINE

Partner access stops at BI

External partners receive read-only shared dashboards. They cannot enter storage, notebooks, or orchestration.

Administration stays separate

  • Administrators hold admin rights everywhere.
  • Engineers write across the platform.
  • Scientists write only in notebooks.

Analyst scope is narrow

Analysts query governed data and author BI content, while object storage, notebooks, and workflow controls remain unavailable.

THE HEADLINE

+

Article is the root

+

Author, Tag, and the join table only exist to describe Article. If you're thinking about a feature, start here and trace outward.

+
+
+

Many-to-many via a join

+
  • Tags aren't embedded on Article
  • ArticleTag is a pure join — no metadata
  • Dashed border signals it's not a primary entity
+
+
+

Cardinality over arrows

+

Plain lines with 1/N at the ends read cleaner than crow's feet at this size. Every relationship carries both numbers.

Five candidate cause categories investigated after a 90-minute checkout latency incident. The confirmed root cause carries the diagram's only accent — everything else stays in the neutral ink/muted palette so the reader's eye lands on the answer, not the investigation.

ROOT CAUSE

+

Data — missing index

+

No index on orders.created_at; the query planner fell back to a sequential scan once the table crossed 3x its forecast size. The single confirmed cause — every other category was ruled out.

+
+
+

Contributing categories

+

Deploy (canary skipped, config drift), Runtime (pool cap 20, GC pauses), and Observability (no p99 alert, 5-minute dashboard sampling) all slowed detection but didn't cause the regression themselves.

+
+
+

People

+

A mid-incident on-call handover cost roughly ten minutes of context — worth fixing, not the root cause.

Should you write this as a skill?

+

A three-decision triage for turning a one-off workflow into something reusable. Shape carries type — ovals bracket the flow, rectangles are steps, diamonds are decisions.

+

WHY THIS FLOWCHART

+

Most things aren't skills

+

The happy path is narrow on purpose. Only workflows that clear all three gates earn the overhead of a reusable skill — everything else is better as a project note.

+
+
+

Shape, not color

+
  • Oval bookends the flow
  • Rectangle is a step
  • Diamond is a decision
  • Color reserved for the happy path
+
+
+

Every branch gets a label

+

Unlabeled branches turn a flowchart into a maze. Yes/No is fine; conditions in mono when the logic is richer.

Q2 product launch · 12-week plan

Three phases from research through launch. Design review in week 8 is the critical gate — development doesn't continue until sign-off.

+

CRITICAL GATE

+

Design review — week 8

+

Development begins in week 7 but the full build is contingent on design sign-off. Starting before the gate means dev can fix implementation issues early, not rebuild from scratch post-review.

+
+
+

Discovery ↔ Design overlap

+

User interviews (W2–W4) overlap with wireframes (W4–W6) by one week. This is intentional — the first round of interview findings feeds directly into iteration without a formal handoff ceremony.

+
+
+

Float in the schedule

+

Beta testing (W10–W12) has two weeks of overlap with dev end (W11). If dev slips by one week, beta absorbs it. If dev slips two weeks, the launch date moves — there is no buffer beyond that.

Ingestion · Apache NiFi

+
+
+

Data collection

+
+
    +
  • Collects from WEB (HTTP/REST), FTP, database CDC, and legacy file exports
    • +
  • No-code dataflow routing with back-pressure and guaranteed delivery
    • +
  • Lands raw data into MinIO and exposes it to Trino simultaneously
    • +
  • Orchestrated by Airflow DAGs for scheduled batch and event-driven runs
    • +
+
+
+

Storage · MinIO / S3

+
+
+

Object store (focal)

+
+
    +
  • S3-compatible API — single storage surface for all tools in the stack
    • +
  • Holds raw, cleansed, and curated layers (bronze / silver / gold paths)
    • +
  • Trino virtualizes directly over MinIO buckets — no ETL copy step needed
    • +
  • Python notebooks write model outputs back as Parquet for further querying
    • +
+
+
+

Query & Serve · Trino + Superset

+
+
+

Analysis & visualization

+
+
    +
  • Trino federates SQL queries across MinIO, databases, and APIs in one query
    • +
  • JupyterLab notebooks run Python and R for statistical modeling and ML
    • +
  • Superset dashboards connect to Trino for live, governed report delivery
    • +
  • Active Directory enforces row- and column-level access across all surfaces

Five horizontal phases (Sources → Ingestion → Storage → Transformation → Visualization) plus three cross-cutting verticals (Orchestration, Security, Observability) rendered as a reserved right strip. Two cross-cutting bars stack below the cluster — Identity and Monitoring — each paired 1:1 with a vertical chevron. The diagram is fully parametric: chevrons, sources, components, and connections drive every coordinate.

Vertical · Orchestration

+
+
+

Workflow automation

+
+
    +
  • Apache Airflow runs as a full-width bar at the top of the cluster — visible to every cluster node
    • +
  • Trigger drops are always dashed (style: trigger), originating from the bar's bottom edge
    • +
  • The vertical Orchestration chevron in the right strip labels the cross-cutting column
    • +
  • One bar component per vertical chevron — enforced by the pairing rule
    • +
+
+
+

Storage · MinIO / S3 (focal)

+
+
+

Object store hub

+
+
    +
  • Single focal node — accent border, accent ink, accent connectors
    • +
  • Every edge touching the focal node is automatically style: primary (accent stroke)
    • +
  • Trino virtualizes MinIO buckets — read-back drawn as style: query (dashed dim)
    • +
  • Notebooks consume curated data; their output writes back as Parquet
    • +
+
+
+

Verticals · Security + Observability

+
+
+

Cross-cutting concerns

+
+
    +
  • Multiple cross-cutting bars stack below the cluster, one row per concern (44 px each)
    • +
  • Each crosscut pairs 1:1 with a vertical chevron in the right strip (count constraint)
    • +
  • Bars emit no individual connectors — semantic is "applies to everything above"
    • +
  • Components carry an optional color override (Identity Manager rendered in rust-red here) — applies to border, icon, and name; connectors stay topology-driven

THE HEADLINE

Two manual bottlenecks

  • The shared drive has no version history.
  • The portal depends on a person-led refresh.
  • Spreadsheet copies break traceability.
+

File-based exchanges

  • Stores export nightly CSV files.
  • Suppliers email changing workbooks.
  • Regional packs leave as PDF attachments.
+

System that remains

The on-premises relational database remains the inventory and finance source of record while the surrounding handoffs are modernized.

Trial to paid: the first week

+

One persona, five stages from signup to upgrade. The sentiment curve is the point: a confident start, a dip when the free-tier export limit hits with no warning, and a recovery once the team upgrades.

TROUGH

+

Hit the limit

+

The export cap arrives with zero warning at 80% usage, and the only way out is a pricing page that's three clicks from the blocked screen. This is the one stage worth fixing before anything else.

+
+
+

Recovery, not just relief

+

Sentiment climbs back to neutral at upgrade rather than back to high — the friction is remembered. Track this cohort's 90-day retention separately from users who never hit the limit.

+
+
+

Early signal

+

Sign up and invite team both read high. The trial's first impression is working; the problem is entirely mid-funnel.

Platform team board

+

A state census of platform-team work, not a flow — no connectors, just where each ticket sits and whether a column is over its WIP limit. In progress is running one over budget, and one ticket is stuck on a vendor maintenance window.

OVER LIMIT

+

In progress · 4/3

+

One ticket over the stated cap, and the reason isn't throughput — it's Postgres 16 upgrade, blocked on a vendor maintenance window. Pulling more work in won't help until that window opens.

+
+
+

Review · 2/3

+

Under limit, but one of the two cards is waiting on an external vendor SSO integration rather than internal review time — worth tracking separately from cards actually being reviewed.

+
+
+

Done

+

Capped at two visible entries; older completions roll off the board rather than accumulating indefinitely.

AI app stack · Where the work actually happens

+

Five layers between silicon and the user. Most teams over-invest in the model and under-invest in the harness — which is the layer that decides whether the app feels magical or flaky.

+

THE HEADLINE

+

Coral marks the layer that pays rent

+

Swapping models is a knob. Rewriting the harness is a product decision. The coral band says: this is the layer where you out-execute the competition, not the one where you chase leaderboards.

+
+
+

Reading the stack

+
  • Abstraction rises up the left column
  • L-index on the left, note on the right
  • Hairlines between layers, no shadows
  • Fill shade shifts from paper-2 to white
+
+
+

Why only five

+

Six-plus layers become a legend, not a diagram. Five holds the whole thing on one screen — every band readable without squinting, every note a scan away.

Organic search driving 55% of new signups

+

75% week-over-week growth over 8 weeks — from 120 to 210 signups. Two long-form guides published in W4 account for the step change. The W5 dip is a weekday holiday effect.

+
+
+

Direct: stable core

+

22% growth (80→98) — this is mostly returning users and brand-aware discovery. The near-flat slope is a healthy baseline, not stagnation. It means the product retains its direct audience while organic expands.

+
+
+

Referral: early signal

+

67% growth (45→75), driven by one integration partner. Volatile week-to-week but directionally positive. Worth a dedicated channel review before investing further in partner programmes.

THE LOOP SIGNAL

+

The dashed lines are the product

+

Shipping work matters once. Writing the result back makes the next pass faster, safer, and better informed.

+
+
+

Memory compounds

+
  • Evidence survives the handoff
  • Outcomes update the playbook
  • One record stays shared
+
+
+

One human gate

+

Decide is the only focal station because accountability should remain visible inside an improving system.

THE HEADLINE

+

Aggregated is the query surface

+

Dashboards read stable metrics instead of recomputing joins across raw commerce records.

+
+
+

Quality rises by tier

+
  • Identifiers are masked first
  • Events and orders are validated
  • Metrics are versioned for reuse
+
+
+

Two write modes

+

Trino handles repeatable promotion jobs; notebooks support exploration before logic is operationalized.

How Claude Code composes context from every folder level above. Each outer ring is a broader scope; the innermost box is where the work happens — inheriting every instruction above it without a single import statement.

THE HEADLINE

+

Containment is the config

+

Every CLAUDE.md inside a parent folder implicitly wraps the one below. No manifest, no import graph — the file tree itself declares scope, so renaming a folder is the only migration you'll ever run.

+
+
+

Reads outside-in

+
  • Global rules load first
  • Each parent narrows context
  • Innermost file gets the last word
  • Conflicts resolve by specificity
+
+
+

Five levels is the ceiling

+

Past five rings the diagram stops teaching — and so does the filesystem. If you need six levels of instruction, you probably need two projects instead.

Use when

The reader needs to know who owns what, where to route work, and which roles are active vs. still being wired.

Keep nodes short

Name, invocation path, and 2–4 scope words. Put detailed operating rules below the figure.

Show gaps

Unavailable owners and missing routes should be dashed, not hidden. They are operationally useful.

THE PIVOT

Stock allocation commits the order

The focal handoff turns a verified order record into an actionable warehouse pick list.

+

Ownership stays explicit

  • Support verifies and closes
  • Warehouse allocates, picks, and packs
  • Finance captures the final payment
+

Payloads change with the work

Records become tasks, then documents, transactions, and a customer-visible status.

Four layers of output, ordered by how rarely they ship and how far they travel. The base keeps you present. The apex defines the body of work — and it's the only layer anyone quotes back a decade later.

THE HEADLINE

+

One coral layer, on purpose

+

A five-colour pyramid is a children's diagram. Reserving coral for the apex makes the whole structure actually say something: this is the rarest thing you'll make, and it's the one the rest of the pyramid is feeding.

+
+
+

Width tells the truth

+
  • ~240 short posts a year
  • ~48 essays
  • ~4 long-form guides
  • 1 flagship every 3–5 years
+
+
+

Pyramids only work for hierarchy

+

If your four categories don't have a rarity order — if a bullet list would communicate it — use bullets. Pyramids promise you're trading volume for value as you climb.

Workplace 2030 · Remote × AI automation

+

Four named futures, one matrix. Scenario planning in the consultant 2×2 form — two independent drivers, four equal-weight cells, one quadrant carrying the coral bet.

+

THE HEADLINE

+

Name every future

+

Scenario planning fails when three of the four cells are placeholders. Forcing a name on each future — even the "won't happen" ones — surfaces the assumptions hiding in the axes.

+
+
+

Variant rules

+
    +
  • Double-ended arrows on both axes (spectrum, not flow)
    • +
  • Named cells, not plotted items
    • +
  • Driver name + range on each arrow tip
    • +
  • Coral on one focal quadrant max
    • +
+
+
+

When to use

+

Reach for the consultant 2×2 for scenario planning, positioning frames, or strategy sessions where four named archetypes beat a plotted point cloud. If you're prioritising, use the standard quadrant instead.

THE HEADLINE

+

One coral dot, on purpose

+

A 2×2 with four coloured quadrants is a poster, not a decision tool. Reserving coral for the single item you commit to tomorrow makes the matrix actually prioritise.

+
+
+

Axes labelled at ends

+
  • HIGH / LOW at the extremes
  • Arrows show direction
  • No labels at midpoints
  • The cross is 1px ink, not a box
+
+
+

Empty BR isn't wasted

+

Two items in "Avoid" is informative — it says the team considered them and rejected them. A blank quadrant would leave you wondering.

RECOMMENDED

+

MinIO

+

9 across the board, weakest only on large-object reads. The clear pick when small-file performance and Iceberg integration matter and you can run the operator yourself.

+
+
+

Amazon S3

+

The reference implementation: top-class on large-object reads and write throughput, but a hard step down on operational simplicity once you factor in IAM, lifecycle, and bucket policy sprawl.

+
+
+

Ceph

+

Capable across the board, but the lowest score on operational simplicity. Pick it when you already run Ceph or need block + object + file from one cluster — not for a fresh greenfield.

+
+
+

Google Cloud Storage

+

Solid middle path. No standout dimension — which is itself an answer when the team optimises for "boring, managed, fine."

+

Checkout is slow in two different ways

+

Five services, one week of request latency, one amplitude scale. Each ridge is the share of that service's own requests in each 40 ms bin — so the ridges compare shape, not traffic. Four of them have a single hump and a thinning tail; checkout-api has a second, smaller peak past 300 ms, which is a different failure from simply being slow.

+
+
+

FOCAL · CHECKOUT-API

+

A second peak is not a long tail

+

About a third of checkout's requests land past 280 ms, and they arrive as a distinct bump peaking near 360 ms rather than as a thinning tail. A tail says "sometimes slower"; a second peak says there are two paths through the code and one of them is always slow. Its p50 is 160 ms and its p99 is 400 ms — both true, and neither says the requests between them arrive in two clusters instead of one spread.

+
+
+

Height is share, so the ridges compare shape

+

static-cdn is the tallest ridge because its requests are concentrated in three bins, not because it serves the most traffic. Each ridge is normalised to its own service's request count and then drawn on one shared amplitude — that is what makes the silhouettes comparable, and it is the one thing a ridgeline must never fudge.

+
+
+

Overlap is deliberate; occlusion would not be

+

Ridges sit 56 px apart and the tallest rises 86 px, so peaks cross the row above and the stack reads as depth. The rule is that no peak may reach the row two above it — past that a peak hides behind a peak, and the fix is more pitch, never a smaller amplitude on one ridge.

EDITORIAL POINT

+

Flaky reruns

+

1,000 of the 12,000 monthly minutes — about 8% of the whole budget — go to tests that failed once and passed on rerun. That's the one line item this diagram argues for cutting.

+
+
+

Where the minutes go

+

Unit tests and E2E together are three-quarters of the budget (9,200 of 12,000 minutes). Build and lint are comparatively cheap at 1,900 and 900.

+
+
+

Net outcome

+

9,400 minutes pass clean, 1,600 fail for real. The remaining 1,000 are pure overhead — neither signal nor failure, just retries.

18 deploys/week with a 3-day lead time. This combination is achievable because they own the full stack — no cross-team approval gates, and their CI pipeline runs under 4 minutes.

+
+
+

Correlation is clear

+

Every team to the right of the median deploy frequency (8/week) is also below the median lead time (12 days). The relationship isn't causal — both are symptoms of the same underlying practice: small, frequent, reversible changes.

+
+
+

Two outliers worth examining

+

The team at (2,20) ships rarely and slowly — high coupling, long approval chains. The team at (12,10) deploys frequently but with higher-than-expected lead time — likely a large monorepo with slow integration tests.

Article request, cold cache

+

How a content site serves a reader when the requested slug isn't already sitting in Cloudflare's edge cache — origin render, beacon, and back in one round trip.

THE HEADLINE

+
+ +

Edge handles the hot path

+
+

On subsequent reads the whole exchange collapses to M1 → M5. Cloudflare serves the cached HTML without waking the origin. The coral arrow is the only one the reader ever perceives.

+
+ +
+
+ +

Origin render on miss

+
+
    +
  • Astro SSRs MDX on cold cache
    • +
  • Returns HTML + cache headers
    • +
  • Edge stores the result
    • +
  • Next reader skips the origin trip
    • +
+
+ +
+
+ +

Analytics is fire-and-forget

+
+

The pageview beacon is dashed for a reason: the reader never waits on it, and a failed beacon never breaks the page.

A resource call under a bearer token, with an ALT fragment for the happy path versus a 401 that refreshes via Auth and retries. Async audit is fire-and-forget with an open arrowhead.

THE HEADLINE

+
+ +

Valid token is one hop

+
+

When the access token is still good, the ALT frame collapses to a single coral return. That is the path most readers should see first.

+
+ +
+
+ +

401 drives refresh

+
+
    +
  • API answers 401, not a hard fail
    • +
  • Client posts refresh to Auth
    • +
  • New access returns dashed
    • +
  • Retry re-enters the resource API
    • +
+
+ +
+
+ +

Async uses open arrows

+
+

The audit event is dashed with an open arrowhead so it never reads as a blocking return. Returns stay filled even when dashed.

FOCAL · RECOMMENDER

+

The recommender went from fourth-slowest to slowest

+

238ms to 431ms. It is the only line that rises, so it crosses three of the other four — all but Auth, which stays below it throughout. Where it crosses on the page is an artifact of joining two endpoints with a straight line: this chart cannot say when the regression started, only that it is there.

+
+
+

Search won the most and is still the second slowest

+

512ms to 208ms, down 304 — the steepest slope here. It started so far above everything else that the largest absolute win still leaves it near the top. Level and change share one scale, which is what lets you read both at once.

+
+
+

Auth barely moved because it had nothing to win

+

154ms to 121ms, down 33. Nearly flat, and low on the axis — a shallow slope down here means a service that was already fast, while the same shallow slope near the top would mean a cache that did not work.

The four states a post passes through from draft to archive, with the rejection loop made explicit. Published is the state the team optimizes for — hence coral.

THE HEADLINE

+

Published is the win state

+

Everything flows toward Published. The rejection loop is dashed because it's a detour, not a failure — the article is still in-progress.

+
+
+

Reject is a loop, not a dead-end

+
  • Dashed to signal detour
  • Returns to Draft, not a new state
  • Review feedback is the action
+
+
+

Archive keeps the URL

+

Archived preserves the redirect map so inbound links survive. Only Purge removes the record entirely.

Narrative order runs left to right — find the data, build the report, share it, trust it — while priority runs top to bottom. The release-cut line under MVP is the editorial point: everything above it ships first, and the riskiest bet, row-level permissions, lands in Release 2.

RELEASE CUT

+

MVP · 4 stories

+

Keyword search, a table with one chart, a public link, and a last-updated stamp — enough to answer "what is the whole story" without shipping every activity's full depth. Everything below the cut line waits.

+
+
+

Release 2 · 3 stories

+

Saved filters and scheduled email round out the workflow, but row-level permissions is the riskiest bet in the map — untested access-control logic sitting right after the cut, not buried in "Later".

+
+
+

Later · 2 stories

+

Natural-language query and anomaly alerting are named and ordered, not promised — three slices is the ceiling before nobody believes the sequencing anymore.

Publishing an article

+

Four actors, seven steps, three handoffs. The step each person owns lives in their lane — arrows crossing lanes are where coordination happens.

THE HEADLINE

+

The deploy trigger is the risky edge

+

Every other step lives inside one person's head. The Editor→CI/CD handoff is where automation takes over and humans lose the ability to undo — hence coral.

+
+
+

One owner per step

+
  • No step crosses two lanes
  • Handoffs are arrows, not shared steps
  • Dashed arrow = revision detour
+
+
+

Uneven step counts are fine

+

The Reviewer lane has one step; CI/CD has two. Lanes don't need to match — they exist to make ownership unambiguous.

Product launch · fourteen months

+

Five design moments from the first post to the current schematic overhaul. Spacing is proportional to calendar time — the five-month gap between v1 and v2 is genuinely wider on the page.

+
+

THE HEADLINE

+

v3 set the complexity budget

+

January's design overhaul is the pivot — the rule that no diagram exceeds nine components comes from there, and it's why this skill exists in the form it does.

+
+
+

Honest spacing

+
  • 5 months between v1 and v2
  • 4 months between v2 and v3
  • 3 months between v3 and now
  • Cadence is tightening, not gaming the axis
+
+
+

Alternate label placement

+

Above / below flipping prevents label collision without forcing a second row. Five events on one baseline stays legible.

Claude Code skill taxonomy

+

Three tiers, one root. The full skill library fans out from a single idea — and every leaf descends through exactly one category. Orthogonal connectors, one coral accent, nothing else.

+ +
+
+

THE HEADLINE

+

One root, one coral dot

+

A taxonomy is a promise: every child has exactly one parent. Coral lives on the root because that's the only node the tree is actually about — everything else is a descent.

+
+
+

Connectors are orthogonal

+
  • Parent drops vertical
  • Horizontal bus connects siblings
  • Each child drops into its top edge
  • No diagonals, no curves
+
+
+

Uneven breadth is honest

+

Design and Engineering fan to two leaves; Research drops to one. The layout reflects the real shape of the library, not a forced symmetry.

Population by continent, mid-2023. Asia holds 4.78 billion people — 59% of everyone alive, and more than the other five continents put together.

+
+
+

One cell carries the story

+

Asia is the focal cell because it is the finding, not because it sorts first. Nearly six of every ten people alive are inside that rectangle.

+
+
+

How to read it

+

Cells are laid out squarified, largest first, so aspect ratios stay near 1 and areas stay comparable by eye. Among the other five, stronger contrast means larger.

+
+
+

What the chart doesn't show

+

Population, not growth. Africa's cell is under a third of Asia's today, and it is the one adding people fastest — this is one moment, not a direction.

THE HEADLINE

+

PaymentMethod is the contract

+

Card and BankTransfer both realize the interface — the dashed line with the hollow triangle. PaymentService only ever talks to the interface, never to a concrete method.

+
+
+

Composition means it dies with the whole

+
  • OrderLine has no life outside an Order
  • Filled diamond sits at Order, the owner
  • Order also just references Customer — no shared lifecycle there
+
+
+

What's deliberately left out

+

No getters or setters, no full attribute lists. Every member shown earns its place in the argument this diagram is making.

Good design · Desirable × Feasible × Viable

Three tests every product has to pass before it earns the word "shippable." Miss one and you get a prototype, a vaporware demo, or an internal tool nobody asked for. Coral marks the intersection worth the work.

THE HEADLINE

+

One sweet spot, in coral

+

Three overlapping circles create seven regions. Six of them are diagnostic — they name the failure mode. Only the center earns the coral. If every region is colored, the diagram stops prioritizing anything.

+
+
+

The three tests

+

The named traps

Prototype (loved, buildable, no model). Vaporware (loved, profitable, un-buildable). Internal tool (buildable, profitable, unloved). Labeling each one makes the map more useful than the center alone.

AI assistant product · Wardley map

The value chain behind an AI assistant, from the user-facing need down to raw infrastructure, positioned against how evolved each component is. The one arrow is the map's point: agent orchestration is commoditising, so betting engineering time on a bespoke orchestrator is a shrinking advantage.

MOVEMENT

+

Agent orchestration

+

Still custom-built today, but the open-source orchestration frameworks maturing this year push it toward product. Betting differentiation here has a shrinking half-life.

+
+
+

Eval harness

+

Genesis-stage and specific to this product's failure modes. No off-the-shelf harness captures what "good" means for this assistant yet — worth the custom build.

+
+
+

GPU compute · Object storage

+

Fully commoditised. Buy, don't build — any engineering time spent here is time not spent on the parts of the chain that are still genesis or custom-built.

Do not capture after an arbitrary delay. +3. **CSS owns presentation.** Use CSS transitions/keyframes for appearance and travel. Minimal inline JavaScript is allowed only to bind explicit controls, update step/state attributes, schedule deterministic steps, and update the dedicated live-status region. No fetches, markup injection, path measurement, or mutation of semantic diagram labels or values. +4. **One clock.** Use `--motion-fast: 160ms`, `--motion-step: 480ms`, `--motion-hold: 720ms`, and `--motion-total` ≤ `8000ms`; derive delays from integer steps. No randomness, springs, or transition-event timing. +5. **Explicit order.** Mark items `data-motion-item data-step="N"` for integer steps 1–8. DOM order follows narrative order. At most two items enter per step. +6. **Stable end.** Completion exposes all items and sets `data-frame="end"`. Replay resets to step 0 first. Pause clears the pending timer and resume continues from the same step. +7. **Scoped state.** Controls operate on their nearest `[data-motion-root]`; IDs, timers, live regions, and step state never cross figure boundaries. +8. **Failure-safe startup.** JavaScript adds `.motion-ready` only after controls are bound and the initial render succeeds.

Controls operate only on their nearest `[data-motion-root]`. + +Use [`assets/template-motion.html`](../assets/template-motion.html) rather than inventing another controller. Its inline controller is the executable implementation contract: copy that script body verbatim. The skin linter rejects modified or additional controllers, even when they carry `data-diagram-controls`. Replace diagram content and slug-prefixed IDs, but preserve the controller and its state/control attributes. + +## Reduced motion, color, and accessibility + +- `prefers-reduced-motion: reduce` initializes at the complete static frame, disables and hides every playback control, hides decorative movement, and exposes `data-motion-state="reduced"` plus status text that playback is unavailable. It never presents partial-step announcements beside a complete frame. +- The SVG's `` and `<desc>` describe the complete meaning, not the animation. Interaction instructions remain visible HTML text. +- Decorative overlays carry `aria-hidden="true" focusable="false"`.

Set `--motion-total` to step count × `--motion-hold` and keep it within the 8-second budget. Use one `setTimeout` chain per root, derive its hold from `--motion-hold`, clear it on Pause/Replay/page hide and immediately after rendering the final step, and never use `setInterval` for semantic playback. Pause when `document.visibilityState` becomes hidden and do not catch up later. `?motion=step&step=N` may expose an exact zero-duration frame for visual regression only when `N` is a non-negative base-10 integer from 0 through `data-step-count`; missing, fractional, negative, and over-budget values leave normal playback in place. + +The final-state capture contract is synchronous: `?motion=static`, `<html data-motion="static">`, or mode `none` exposes every semantic item, hides controls and decorative overlays, and sets `data-frame="static"`. Wait for `document.fonts.ready` before capture. Two captures from the same URL, viewport, fonts, and device scale must be pixel-identical; random delays, generated IDs, clocks, and runtime path measurement are forbidden. + +## Export and verification + +PNG and SVG exports are static final-state artifacts unless the user explicitly requests a named step. Before capture, open `?motion=static`, await `document.fonts.ready`, and assert `data-frame="static"`.

Disable JavaScript: the complete diagram remains visible and meaningful. +2. Emulate `prefers-reduced-motion: reduce`: the final state is complete, playback controls are hidden and disabled, and the DOM status says playback is unavailable. +3. Use keyboard only: Tab reaches each native control; Enter/Space operate it; Left/Right/Home/End step without moving focus. +4. Pause, resume, and replay twice: ordering and final state are identical. +5. Capture `?motion=static` twice after `document.fonts.ready`: pixels are stable. +6.

Run the pre-output checklist (§9) to verify before producing any diagram. + +1. **Rounded right-angle (orthogonal) connectors are mandatory.** Never use diagonal `<line>` or straight slanted paths between nodes that don't share an x or y axis. Every bend must be a quarter-arc with `r=8` (or `r=6` minimum for tight layouts). See `references/type-architecture.md` for the elbow-path formula. Reserve plain straight `<line>` only for connections whose endpoints share the same x or y coordinate. Diagonal connectors are an automatic fail. + +2. **Label-to-connector margin: 6–10px gap, always.** A label must never sit *on* its arrow — the connector must remain visible. Place the label centered above (or beside, for vertical segments) the line with a **minimum 6px gap** between the bottom of the label's mask rect and the connector stroke. The opaque mask rect prevents the arrow from bleeding through, but the *visible* gap between mask edge and line preserves the reader's ability to trace the connection. If the label is large enough that 6px feels cramped, push it to 8–10px. Never let the mask rect touch or overlap the stroke. + +3. **No overlapping connectors.** Two connectors must never share the same stroke path, run parallel on top of each other, or be drawn on top of each other for any segment. When two orthogonal arrows must cross at a single point, apply the **bridge / hop** primitive (see `references/type-architecture.md` § Crossing arrows). When two arrows naturally want to overlap, offset their routing by ≥12px so each line is independently traceable. If you find yourself stacking connectors, redesign the layout — it means two nodes are too close, or the diagram is over budget (split into overview + detail). + +4. **Shared edge → fan the attach points.** When two or more connectors enter or exit the *same edge* of a box, each must have its own distinct attach point along that edge — **no two connectors may share a single point on a box**. Spread the attach points evenly along the edge with **≥12px** between adjacent points (8px minimum for very small boxes). Routing rules: + - For N connectors on an edge of length L, attach point `k` (1..N) sits at offset `L * k / (N + 1)` from the edge's leading corner. + - When the connectors fan out to destinations on different sides, route each one orthogonally from its own attach point — no merging strokes near the box. + - When two parallel connectors run in the same direction, keep them ≥12px apart along their entire length, not just at the attach point. Each arrow must remain independently traceable end-to-end. + + No connector may hide another. If you can't tell two arrows apart at a glance, the layout has failed. + +5. **A connector must not pass behind a box that isn't its source or destination — except when the box is geometrically unavoidable on a direct orthogonal path.** Reroute around intervening boxes by default. The only legitimate exception is when a cross-cutting node (e.g., a footer service, a horizontal layer bar) physically sits between the connector's source and destination on the only straight path between them — for example, a `METRICS` arrow exiting an `Observability` footer bar and rising into a zone above must cross the `Active Directory` footer bar that sits between them. In that exception: + - The stroke must be **dashed** (e.g., `stroke-dasharray="4,3"`) to signal "transit, not interaction" — it tells the reader the intervening box is not an endpoint. + - The label sits at the **visible end** of the connector (typically near the source) so it doesn't fall behind the intervening box. + - No marker (arrowhead) may land on the intervening box's edge — the marker resolves at the true destination only. + + When in doubt, reroute. The exception exists for the narrow case where rerouting is geometrically impossible, not as a shortcut to avoid layout work. + +6. **A label mask must not overlap a node drawn after it.** Rule 2 keeps the label off its own connector; this one keeps it off the boxes. Because nodes are painted after labels, a mask that lands partly inside a node is covered by the node fill and the text renders as a fragment sitting on the node border. Place the label on a segment of the connector that runs through open canvas — for a connector leaving a node's right edge, that means clearing the node's `x + width` before the mask starts. A mask fully *inside* a node is a badge chip and is fine; a mask overlapping a zone container is fine too, since zones are painted first.

Infrastructure disappears. | + +`balanced` and `simplified` sit inside the standard complexity budget (SKILL.md §7). **`faithful` deliberately exceeds it** — that's the trade, and it comes with conditions: + +1. **Zoning is mandatory.** Above 9 nodes, every node belongs to a labeled zone (2–4 zones, hairline-bordered, `paper-2` fill, mono uppercase zone label at top-left). An unzoned 20-node diagram is a wiring diagram, not a schematic. +2. **Connector rules don't relax.** SKILL.md §6 rules 1–5 still apply at 24 nodes. If you can't route it without overlaps, you're over the real ceiling — split. +3. **Above 24 nodes, split.** Produce an overview (zones as nodes, `balanced` grammar) plus one detail diagram per zone. Name them `<base>-overview.html`, `<base>-<zone>.html`. Never ship a 40-node single canvas. +4. **Accent stays at 2.** More nodes never buys more focal elements. + +### Degrade ladder + +When the source has more than the level allows, cut in this order and stop as soon as you're under budget. Never cut ad hoc. + +1. **Decorative cells** — sticky notes, free-floating text, title blocks, watermarks, the source's own legend. (Notes worth keeping become annotation callouts — max 2, see [primitive-annotation.md](primitive-annotation.md).) +2. **Exact duplicates** — N identical workers/replicas/shards become one node labeled `Worker ×N`. +3. **Leaf clusters** — a container whose children are all leaves collapses to the container: `Core Services` replaces its three boxes. The extractor lists these under *collapsible groups*. +4. **Degree-1 sinks that don't change the story** — a monitoring hook, a log bucket, an archive tier. +5. **Cross-cutting infrastructure** — logging, metrics, secrets, CI. At `simplified` these go without asking; at `balanced` keep at most one, and only if the diagram is about it. +6. **Still over?** Split into overview + detail. Splitting beats shrinking. + +Anything cut in steps 2–6 goes in the fidelity ledger (§5). Step 1 doesn't need reporting. + +--- + +## 4.

Noto Sans KR ships in the skin's font link, so it leads that stack and the local families follow it; the register, floor, and title rules Korean needs beyond the font live in [`style-guide.md`](style-guide.md#korean-labels). For mono sublabels use `'Geist Mono', 'Noto Sans Mono CJK JP', monospace` (Japanese) or `'Geist Mono', 'Noto Sans Mono CJK KR', monospace` (Korean). Budget **1em per full-width CJK glyph**, not a small percentage over the average Latin glyph; a project-specific treemap verifier uses that conservative contract for Unicode wide/full-width characters and treats combining marks as non-advancing. Prefer 12px names over 8px sublabels for CJK, which goes muddy below 10px. Actual width still varies by fallback font, so run the relevant geometry verifier after translating labels. + +--- + +## 5.

A Korean `` element extends its own family — never swap the skin: + +```svg +결제 서비스 +``` + +Both Noto faces ship in the font link above, so the web font resolves before any locally installed one and the same file renders identically on macOS, Windows, and a reviewer's browser. The local families follow it for offline viewing. Page titles need the serif equivalent — `'Instrument Serif', 'Noto Serif KR', serif` — or a mixed Latin/Korean title resolves Hangul through the platform's generic serif and the two halves disagree. Google's `css2` endpoint slices Korean by unicode-range, so a diagram with a handful of Korean labels downloads only the slices it touches. The four templates carry both faces because a new diagram may contain Hangul; the shipped Latin-only examples keep the shorter link, since a file with no Hangul has nothing to resolve. + +**Width budget.** Measure per character, not per script: **every Unicode wide or full-width character costs 1em, every other character costs its face's Latin advance** (0.60em sans, 0.62em mono), and nonspacing/enclosing marks cost nothing. Sum over the string and multiply by the font size for the text width, then add padding and round the box up to the next multiple of 4. A project-specific treemap verifier enforces exactly this text width for treemap cell labels; the padding and rounding are authoring convention, and no other type carries an automatic check, so on those the budget is yours to hold. + +Counting by script is the trap. `주문 v2.1` is two full-width syllables and five narrow characters; a formula that tallies Hangul, Latin letters, and spaces silently drops `2`, `.`, and `1` and sizes the box for four of its seven characters. Every rendered character costs something — measure per character, never per script. + +Three rules follow from Hangul metrics: + +- **Sublabels stay Latin.** Ports, protocols, field types, and URLs are Latin anyway — keep `Geist Mono` there and don't translate them. Hangul in a 9px mono sublabel is unreadable and has no mono face to fall back to. +- **Floor of 12px.** Hangul goes muddy below 12px. If a Korean name doesn't fit at 12px, cut the name — don't shrink the type. +- **Arrow labels, eyebrows, and legend text switch register.** Those slots are 7–8px Geist Mono, uppercase and tracked, which Hangul has neither a face nor legibility for. A Korean label in one of those slots becomes 12px sans at weight 500 with no tracking and no uppercase transform, and its mask rect grows to match (16px tall, width from the budget above, still rounded to a multiple of 4). Latin labels in the same diagram keep the mono treatment. + +**Load-bearing rule:** Mono is for *technical* content (ports, commands, URLs, field types). Names go in Geist sans.

At the domain floor the axis line replaces the gridline rather than doubling it: `rgba(45,49,66,0.25)` 1px, y 40→420. +- **Tick labels:** centered under each gridline at y=440, Geist Mono 8px muted. +- **Axis title:** the value axis carries the family's axis label — Geist Mono 7px muted, `letter-spacing="0.14em"`, centered at x=580, y=456, below the tick labels and clear of the legend rule. A horizontal axis takes the un-rotated form the scatter x-axis uses, not the `rotate(-90 24 230)` form the column charts apply to their y-axis. The category axis needs no title: the row labels name themselves. +- **Dots:** r=6, positioned by value. Style by *series*: the reference end hollow (paper fill, `muted` stroke 1.5px), the focal end solid `accent` with a 1px `ink` stroke. Both marks therefore have a boundary above 3:1 even though the accent fill is not — see below. Fill weight, not hue, carries the pairing. +- **Accent marks the series, not a focal row.** The solid dot repeats on every row — the one place this variant departs from the one-accent rule above, because the two ends must be told apart in each pair. Do not additionally accent a "most changed" row; the sort order already carries rank. +- **Connector:** `rgba(45,49,66,0.55)` 1px, declared before both dots so the dots cap it. It is not the axis hairline: the connector is what says *these two dots are one row*, so it has to clear 3:1 (0.55 gives 3.19:1; the 0.25 the axis uses gives 1.60:1). +- **Endpoint positions round, they never snap.** `x = 200 + (v − floor) ÷ (ceil − floor) × 760`, with `floor` and `ceil` set by the axis rule below, rounded to the nearest integer pixel — at most 0.5px, below one rendered pixel. Data coordinates are exempt from the 4px grid; snapping them moves the data. +- **Value labels sit outside the pair, placed by geometry rather than by series.** A focal value *below* its reference reverses the dots, so derive `x_left = min(x_ref, x_focal)` and `x_right = max(x_ref, x_focal)`: left label right-anchored at `x_left − 12`, right label left-anchored at `x_right + 12`, both baseline `y + 4`, Geist Mono 8px `muted`, each still carrying its own series' value. Keying the offsets to start/end instead puts both labels *inside* the pair on every decreasing row. +- **Floor exception.** A value sitting on the domain floor lands its label at x=188, right-anchored on baseline `y + 4` — exactly the category label's anchor and baseline, so the two texts overlap. When `x_left − 12 < 200`, centre that label above its dot at baseline `y − 10` instead. +- **Legend:** two keys on the legend row — hollow dot, then solid dot, each with its series name. Circular keys centre at `cy=493`, the centre of the bar legend's 10px key rect at y=488, so both sit on the 497 text baseline. The row order goes in the legend or the source line, right-aligned on the same row. + +**Why the dots differ by fill, not hue.** The focal bar pattern above (12% tint + accent stroke) does not transfer to a 6px dot: the 12% tint across a 6px-radius disc contributes roughly 14 square pixels of colour, so the mark reads as its stroke alone and the pair separates by hue only. A solid accent dot against a hollow one separates by shape, survives greyscale and colour-vision deficiency, and leaves hue as redundant encoding. + +**Non-text contrast: the boundary carries it, not the fill.** Accent on paper is 2.86:1 skin-wide, under the 3:1 WCAG 1.4.11 asks of a graphical object needed to understand the content — and shape redundancy does not waive that, because the reader still has to see the mark's edge and the line joining the pair. So neither is left to the accent: the solid endpoint takes a 1px `ink` stroke (11.82:1 against paper, 4.13:1 against its own fill) and the connector takes 55% ink on light, 40% on dark (3.19:1 and 3.24:1). The hollow end already cleared it via its `muted` stroke at 6.11:1 light and 7.07:1 dark. A project-specific dumbbell formula check should assert all four, so a later tint change cannot quietly drop one under the line. The hollow/solid shape difference stays as redundant encoding for greyscale and colour-vision deficiency — do not collapse the two dots to a single fill. + +**Minimum drawn gap — never clamp it.** Both dots carry `r="6"`; the hollow one paints out to 6.75 because its 1.5px stroke straddles the path, so the marks touch at 12.75px of centre separation and below about 16px the pair reads as one blob — on a 0–100 domain across 760px, a data gap of 2.1 units. Do **not** widen the separation to clear it: moving a dot off its scaled position breaks the shared-scale rule below. Keep the true positions and shrink both marks (r=4 touches at 8.75px), or print the two values and mark the row as too close to resolve. + +### Dumbbell element pattern + +```svg + + + + +34 +71 +Platform +``` + +Values 34 and 71 on a 0–100 domain compute to 458.4 and 739.6, rounded to 458 and 740. Had this row fallen instead, the accent dot would sit on the left; the two anchors stay tied to left and right, and each label carries its own series' value. + +**Dark theme.** Dots and labels swap as expected — hollow fill `#2d3142` with `#bfc0c0` stroke, solid `#f08a59` with an `#f5f5f5` stroke, labels `#bfc0c0`. **The hairlines must invert too:** gridlines `rgba(245,245,245,0.08)`, axis `rgba(245,245,245,0.20)`, connector `rgba(245,245,245,0.40)` — the connector again heavier than the axis, for the same 3:1 reason. `rgba(45,49,66,…)` *is* the dark paper colour at every alpha value, so a connector, gridline, or axis carried over from light composites to exactly 1.000:1 — the gap encoding and the scale both vanish. + +### Dumbbell honesty rules + +- **Never truncate the value axis.** `floor` and `ceil` follow the data's range, never its observed extremes — taking `min` and `max` as the bounds *is* the truncation. With `lo` and `hi` the smallest and largest values, the four cases are exhaustive: `lo >= 0` anchors `floor = 0` and rounds `ceil` up past `hi`; `hi <= 0` anchors `ceil = 0` and rounds `floor` down past `lo`; `lo < 0 < hi` brackets both sides, and zero then falls inside the plot — give it a line at its scaled position in the axis-line weight, since it is what every gap is read against. The fourth case is the one a sign-based rule drops: **when every value is zero**, `lo == hi == 0` would make `ceil - floor` zero and the position formula divide by zero, so take a finite fallback span (`floor = 0`, `ceil = 1` in the data's unit) and let every dot sit on the floor, which is the truth. Data that merely *touches* zero is covered by the first two cases, not a special one. A project-specific dumbbell formula check should implement this and prove finite coordinates for all four. The plot width is fixed, so narrowing the domain raises px-per-unit and draws every gap wider: across the same 760px, an 8-point gap is 61px on a 0–100 axis and 152px on a 40–80 axis. Ratios *between* rows survive the zoom — what inflates is each gap's size against the frame, which is how a reader judges whether a gap is large. The gap is the entire claim, which makes this the most common way a dumbbell lies. +- **Both dots share one scale and one unit.** Label both endpoints with their real values. Labelling only the focal end asks the reader to take the geometry on trust. +- **The connector is a gap, not a trajectory.** It encodes the distance between two values and nothing about what lies between them — no intermediate points, no rate, no guarantee the change was monotonic. Do not narrate it as movement. +- **State the row order** in the legend or source line: by one endpoint, by signed change, by absolute change, or by an order the subject supplies (chronological, geographic, ordinal). "By gap" alone is ambiguous — say signed or absolute. What is not allowed is an unstated order, which reads as arbitrary. +- **A row missing an endpoint is disclosed, never imputed and never silently dropped.** Removing incomplete categories without saying so changes the population being compared. Either draw the known end and name the missing value, or drop the row *and* record which rows went and why — a lone dot is otherwise indistinguishable from two coincident dots, which is to say from a genuine zero gap. + +Two of these rules live in a formula rather than a drawing, so they belong in a project-specific generator check: resolve the domain over every sign case, assert finite coordinates and 3:1 marks, and exercise both polarities — including all-zero and zero-touching data, and the sub-3:1 treatments this replaced. Keep the implementation and this reference synchronized. A shipped dumbbell example would additionally owe a check of drawn positions against the values printed at them. + +## Examples + +- `assets/example-bar.html` — minimal light +- `assets/example-bar-dark.html` — minimal dark +- `assets/example-bar-full.html` — full editorial diff --git a/.agents/skills/diagram-design/references/type-data-flow.md b/.agents/skills/diagram-design/references/type-data-flow.md new file mode 100644 index 0000000000..2e05c516c3 --- /dev/null +++ b/.agents/skills/diagram-design/references/type-data-flow.md @@ -0,0 +1,372 @@ +# Data Flow + +**Best for:** visualising how data moves through a pipeline *across organisational roles* — who initiates, who processes, who publishes, and who consumes.

Bottom anchor of Airflow at y=368 (40-px clear from zone bottom at y=408). **Note**: with the canonical layout there's a 76-px gap between the primary row's bottom (y=248) and Airflow's top (y=324).

Use `value` for free-form displayed text + `color` override for arbitrary tinting. +- **Per-row or per-column color tints** — apply `color` per cell only. Whole-row or whole-column highlighting tends to over-emphasize and collapses the matrix into a list. +- **Using `none_label` as a placeholder for "TBD"** — `none` means *no access*. If the permission is unknown, leave the cell empty in inputs but document it elsewhere; don't render an ambiguous state. +- **More than 6 roles** — split into two matrices (e.g., human roles vs service accounts) before exceeding 6 columns. +- **More than 14 components** — split by domain (storage / compute / observability / governance) before exceeding 14 rows. +- **Using the matrix to document *how* permissions are granted** — that belongs in a process or sequence diagram.

Edges keep their topology-driven style from §3. + +**Where the color is applied** (given `C = color`): + +| Element | Light mode | Dark mode | +|---|---|---| +| Container fill (`rect` body) | `rgba(C, 0.06)` | `rgba(C, 0.10)` | +| Container stroke | `rgba(C, 0.35)` (`stroke-width=1` for nodes, `0.8` for bars) | `rgba(C, 0.45)` | +| Role badge stroke (nodes) | `rgba(C, 0.40)` | `rgba(C, 0.55)` | +| Role badge text (nodes) | `rgba(C, 0.85)` | `rgba(C, 1.0)` | +| Icon fill / stroke | `C` | lighten `C` by ~15% (or use `C` if already light) | +| Name text | `C` | lighten `C` | +| Subtitle text | **unchanged** (`muted`) | **unchanged** (`muted`) | +| Connectors touching this component | **unchanged** (still topology-driven) | **unchanged** | + +The subtitle stays muted because it's parenthetical metadata — only the primary identity (name + icon + border) carries the color signal. + +**Rules**: + +- **Never on the focal node.** The focal node is already colored with the accent (§2.7). A `color` on the focal node is ignored — accent wins. +- **Never on source nodes.** Sources live outside the cluster and stay neutral. +- **Cap at 2 custom-colored components** per diagram (in addition to the focal). Three or more colored things erases the signal — the same reason §1 limits accent to 1–2 elements. +- **No color on connectors.** If you find yourself wanting a colored edge, the right move is to pick a different `style` from §3, not to override. + +**Semantic uses** (recommended): +- `#b85450` (rust-red) — Security / Identity (Keycloak, Vault) +- `#5a7d9a` (slate-blue) — Observability (Prometheus, Datadog) +- `#7a8c47` (olive-green) — Governance / Lineage (OpenMetadata) +- `#8c6d3f` (warm-brown) — Backup / DR + +Stick to these unless the user's brand demands otherwise. Random hex per component is exactly the failure mode this skill avoids. + +--- + +## 4. Block branching rules (fan-out) + +The single biggest reproducibility hazard. Fix these rules and the diagram becomes predictable. + +### 4.1 Source fan-out (one source → N components) + +``` +exit_x = source.right +trunk_x = cluster_x - 8 # 4-px gutter before cluster border +``` + +Path per target: `M exit_x,source_cy → H trunk_x → V target_cy → H target.left`. Use Q-bezier corners. + +### 4.2 Component fan-out (one component → N components) + +``` +exit_x = node.right +trunk_x = x_boundaries[index(source.chevron) + 1] + 4 # 4 px past the chevron divider +``` + +Path per target: `M exit_x,source_cy → H trunk_x → V target_cy → H target.left`. + +### 4.3 Fan-out cap + +**Max 3 outgoing edges per node.** Above 3, introduce a hub (usually the `focal` node). The chevron banner is the legend; if a node is fanning out to four downstream targets, it's secretly the hub — make it explicit. + +### 4.4 Bar drops (Airflow → N nodes) + +``` +drop_x(target) = target.cx +drop_y_start = bar.bottom +drop_y_end = target.top +``` + +Straight vertical line, `style: trigger`. One per target. No bends — bar drops never elbow. + +### 4.5 Source vertical staggering + +When multiple sources connect to the same single target (e.g. four sources → NiFi), stagger their entry y on the target: + +``` +entry_y(k) = target.top + 8 + k * (target_h - 16) / (N - 1) # k = 0..N-1, evenly spaced +``` + +This avoids overlapping arrowheads at the target's left edge. + +--- + +## 5. Vertical chevrons — semantics + +Reserved names `Orchestration`, `Security`, `Observability`, `Governance`, `Backup` always render in the right strip (§2.9). Any chevron with `vertical: true` is treated as a reserved-style vertical regardless of name. The rules: + +- **Pairing rule (mandatory, 1:1):** every vertical chevron pairs with exactly one cross-spanning component, and every cross-spanning component pairs with exactly one vertical chevron. The two component kinds that pair: + - `kind: bar` — lives inside the cluster (top row). Conventionally paired with `Orchestration`. + - `kind: cross-cutting` — lives below the cluster, one row per component. Paired with `Security`, `Observability`, `Governance`, etc. + + If the inputs declare a vertical chevron without a paired component (or vice versa), halt and ask the user — the diagram is incomplete. + +- **Count constraint:** `len(verticals) == len(bars) + len(crosscuts)`. The right strip is split evenly among all verticals (§2.9), so visual alignment between a chevron and its bar/row is approximate — the *label* is what matters, not the y-pixel match. + +- **Ordering convention:** declare verticals top-down in the order: bar-paired first (Orchestration), then crosscut-paired in the same order the crosscuts appear below the cluster. This keeps the visual reading order consistent. + +- **No edges:** vertical chevrons emit no connectors themselves. They are *labels for a column of cross-cutting concern*. + +- **No node placement:** no `kind: node` may be assigned to a vertical chevron. Nodes always belong to a horizontal phase. + +- **Right strip presence:** if any vertical chevron exists, the right strip is reserved (`effective_w = 964`) and **all** horizontal chevron widths and cluster geometry shrink accordingly. Do not draw a vertical chevron on top of the cluster. + +The visual contract: the vertical chevron's column visually "owns" the bar/cross-cutting row at its approximate y-band. Orchestration (top of strip) ↔ Airflow bar (top of cluster). Security ↔ Identity bar. Observability ↔ monitoring bar (below identity).

The new type forbids it — always rounded right-angle Q-bezier. +- **Marker not touching the target.** Path ends at the centroid or stops short of the border. +- **Inline `text` connector labels without a mask rect.** The connector line can bleed through the text and it becomes unreadable. +- **Labels sitting on top of the connector line, mid-segment.** Labels belong at the *start* of the connector with a perpendicular margin (see §3.5) — burying them in the middle of the line hides the source-to-destination direction and forces the reader's eye to fight the mask. +- **Tiny text badges as icons.** The source uses 7-px `DB` / `APP` / `EXT` badges; this type uses real 24-px catalog icons. Text badges are only acceptable as the label text, not as the component "icon." +- **Custom color on a focal component.** Focal always wins; user-set `color` silently ignored on `kind: focal`. +- **Footer bar wired to one component.** Footer = cross-cutting layer-wide concern; a connector from a footer to a specific component is a category error (use `type-dp-integration.md`'s AUTH-line pattern only when the footer service truly authenticates *all* components, and even then the line lands at the zone bottom edge, not at a specific tool). +- **> 16 total components or > 5 per zone.** Density cap; split into two diagrams. +- **Mixing orientations within one diagram.** Pick one — `horizontal` or `vertical` — and apply it to every zone. +- **Using `kind: focal` to flag every painful thing.** Focal exists for ≤ 2 narrative pain-points; for "this is bad but not headline-bad", use `color: "#b85450"` rust-red instead. + +--- + +## 9.

The plot sits inside `x` 40 → 956 with the rotated value-axis caption at `x=24`, as in the parent chart, and the legend keeps the house rhythm (rule at `y=462`, `LEGEND` at `478`, key swatches at `492` with their text at `496`), so a reader of bar, line or treemap finds it where they expect. +- **Keep the run narrower than the plot is tall.** The 360px run against a 380px height puts the steepest shipped slope at 35° and the flattest at 4° — the spread you need before "halved" and "barely moved" look like different claims. Widening the run flattens every slope toward horizontal and throws away the comparison the type exists to make; the leftover width belongs to the label gutters, which need it. +- **Label gutters:** on the left, names right-aligned ending at `x=272` and values right-aligned ending at `x=304`; mirrored on the right from `x=696` (values) and `x=728` (names). Size the gutter to the longest name — a name that collides with the axis is the one thing here you cannot fix by moving a coordinate. +- **State captions** in Geist Mono 9px, centred under each axis at `y=440`, tracked `0.14em`. +- **Series count:** 4–10 — deliberately more than the parent chart's cap of 5. That cap exists because eight-vertex polylines tangle in mid-plot; a slopegraph has no mid-plot, so what sets the ceiling here is endpoint labels colliding, not the lines. Below 4 a sentence or a pair of bars says it better. +- **No gridlines.** Every endpoint prints its own value, so a gridline carries nothing the figure has not already said; the two axis rules *are* the scale. This is a real departure from the parent line chart, where the gridlines do the reading. +- **Domain:** pick round bounds that contain the data and state them in the source line. The shipped example runs 100–550ms over `y` 420 → 40, i.e. 0.84px per millisecond. The parent chart's include-zero rule does not bind here: a slope is unchanged by moving the origin, provided *both* axes move together. What a tight domain does do is magnify every slope equally, so state the bounds and let the reader calibrate. +- **Legend keys are a 24px line plus its dot**, not the 16×8 rect the parent section specifies — which is also what `example-line.html` actually ships, the parent prose being stale on this point. A slopegraph key has to show stroke weight, because weight is what marks the focal series. +- **Dots at both endpoints** — `r=3` non-focal, `r=4` focal. Also a departure: the line chart puts dots on the focal series only, because it has eight vertices per series and dots everywhere would be mush. A slopegraph has exactly two per series and both are where a value is read. +- **4px grid** applies to the designed constants — axis positions, gutter edges, state-caption baselines. Endpoint `y` values are data-scaled and exempt; snapping them would move the data. Two inherited constants are also off-grid and stay that way: the legend rule at `y=462` and the `LEGEND`/source baseline at `478`, which every chart type in `assets/` shares. Matching the house rhythm beats matching the grid here — moving them 4px would misalign this variant against bar, line, scatter and treemap to satisfy a rule none of them satisfies either. + +#### Colour + +- **One accent, and an `ink` opacity ramp for everything else** — not the series palette. In a line chart hue is the only way to follow a series across eight x-positions, so `series-1`…`series-4` earn their place. Here every series is named at both ends, so hue would be a second encoding of something the labels already carry, and it would spend the one-accent rule for nothing. +- **The ramp runs 0.80 → 0.62**, ordered by the left-hand value. The hard floor is **0.53** — that is where an `ink` stroke crosses 3:1 against light paper (0.53 measures 3.03:1, 0.52 measures 2.95:1), and every line in this figure is data, not decoration. The shipped ramp bottoms out at 0.62 (3.84:1) rather than hugging the floor, because a ramp whose lightest member is only just legible has no room left to add a series. +- **Note what the ramp does not buy you.** It separates the ends of the range, not adjacent members — 0.80 and 0.74 are not distinguishable at 1.2px, as the shipped example shows. It is there to help trace one line through a crossing. It must never be the only way to tell two series apart; that is the labels' job. +- **The accent marks the editorially focal series, not the best or the biggest.** In the shipped example it marks the one service that got *worse*. +- **Focus is carried by stroke weight, not tone** — 2.4px focal against 1.2px. Check the token you actually ship: `accent` measures **2.86:1 on light paper** and 5.21:1 on dark, so on light paper the focal line has *less* contrast than the ink ramp it is meant to dominate, and weight is the only cue that survives both skins and greyscale. +- **Be honest about what that leaves.** 2.86:1 is below WCAG 1.4.11's 3:1 floor for a graphical object, and a heavier stroke does not raise a contrast ratio — it only makes the mark easier to find. The focal line clears the bar on redundancy rather than on contrast: its position and its two endpoint labels (`ink` at 11.8:1, `muted` at 6.1:1) carry the data, and its accent adds only *which series is focal*, which the legend states in words and the stroke weight repeats. Nothing here rests on the accent alone. This is a property of the skin's accent token on light paper, not of this variant — the focal bar, the focal line and the focal treemap cell inherit it too, so fixing it properly means changing `accent` in style-guide.md. +- **Labels stay `ink` (names) and `muted` (values) on every series, including the focal one.** Accent text at 9–11px misses AA on light paper at that same 2.86:1. A focal value label in accent is the most common way to make a slopegraph fail contrast while looking deliberate. +- **Legend wording must be skin-neutral: "strongest tone", never "darkest".** The ramp is ink-at-opacity, so the top of it is the darkest line on light paper and the *lightest* on dark. A legend that says "darker is higher" ships false in one of the two variants — and it renders perfectly in both, so only reading the dark file catches it. + +#### Honest-data rule + +**Both axes must carry the same scale and the same units.** That is the entire claim of the type: if the scales differ, the angle of every line is fiction. A project-specific slopegraph verifier should gate it. + +- **The two axes must never differ from each other** — not in scale, not in origin, not in transform. A shared *origin* matters as much as a shared scale: shifting one axis tilts every slope by the same amount, so the series still rank correctly against each other while every rate is wrong. That is the harder version to spot by eye, which is why the checker tests slope and origin separately. +- **A domain tighter than zero is fine; an undisclosed one is not.** Both axes sharing a 100–550 window is legitimate, because moving the origin leaves every slope unchanged when both axes move together — this is exactly where a slopegraph differs from a bar chart, whose truncated baseline distorts the ratio between bars. What a tight window does do is magnify all slopes equally, so the bounds go in the source line and the reader calibrates. Log-scaling is a different matter and stays out: it makes the angle mean nothing. +- **Label both endpoints with actual values.** A slope with no magnitudes is a mood. +- **Round once, then draw from the rounded number**, so the printed label, the declared metadata and the drawn `y` are three statements of one number rather than three chances to disagree. +- **If a series is missing an endpoint, drop it and say so.** Never interpolate to complete a line. +- **Crowded endpoint labels are data.** When two series sit a few tenths apart their labels crowd *because the values are close*. Moving a point to open up space converts a legibility problem into a false statement — and it is invisible afterwards, because the label you moved it for now sits comfortably beside the wrong position. This is the specific defect the gate exists for. +- **Two series that coincide at both endpoints cannot be separated at all.** Merge them into one labelled line, or drop one and name the omission in the source line. What you must not do is nudge them apart, which is the same defect as above wearing a better excuse. +- **The straight line is a connector, not a trajectory.** Two endpoints say nothing about the path between them: the underlying series may have dipped, spiked, or crossed three times. So never read an intermediate value off a slope, and never annotate a crossing with a date. In the shipped example one service regresses while four improve, so its line crosses three others; none of the three crossings is annotated, and the card beside the figure says why. + +#### Declaring the values + +**Every visible string that carries meaning is bound to an attribute stating the same thing.** That is the whole contract, and it exists because each unbound string is a place the figure can be made to lie while every geometric check stays green. + +```svg + +BEFORE +AFTER + + + + + +Recommender +238 +431 +Recommender +``` + +Non-focal series: `stroke="rgba(45,49,66,0.68)"` at `stroke-width="1.2"`, dots `r=3`, names at `font-weight="500"`. + +What each binding buys, and what it costs to omit: + +| Binding | Without it | +|---|---| +| `data-from` / `data-to` on the line | The checker would have to read the labels, and a series whose label went missing would drop silently out of the verified set — the exact hole that let a treemap cell ship 50% oversized. | +| `data-end` on a value label | A printed number could not be cross-checked against the value it claims to state. | +| `data-role="name"` on a name label | Two series names could be exchanged between rows, renaming both lines, with every number still correct in isolation. | +| `data-axis` on a state caption | The captions could be swapped, reversing the direction every slope is read in. | +| `data-state` on a state caption | Swapping just the two visible strings leaves both captions in place and reverses the figure anyway. | + +A project-specific slopegraph verifier should require all of them, cross-check each visible string against its binding, and report any label drawn nearer another series' endpoint than its own — a label on the wrong row renames the line. + +**No `transform` on any of it.** The checker reads raw `x`/`y` attributes, so a `transform` on a series line, on a bound label, on an ancestor ``, or in a CSS rule moves the rendered mark away from the number that was verified — `transform="translate(0 80)"` on one line slid its endpoint 80px past every green check. Transforms are rejected rather than resolved: a partial implementation of the SVG transform stack looks like coverage without being it. Bake the offset into the coordinates. The rotated value-axis caption is fine — it is neither verified geometry nor a bound label. + +**Print one complete number per value label.** A unit suffix is fine (`208ms`); a thousands separator that changes the value is not, and neither is a second number in the same label. Reading only the first numeric fragment let the label `512,000` agree with metadata that said `512`. + +#### Anti-patterns + +- Different scales, different units, or different origins on the two axes — the type's one unforgivable error. +- A value axis whose two halves disagree, or a tight domain the source line never states. +- Moving an endpoint to make room for its label. +- More than 10 series (labels collide) or fewer than 4 (a sentence is shorter). +- Three or more state columns — that is the parent line chart, or a bump chart, not this. +- One hue per series instead of the ink ramp plus a single accent. +- A value label in `accent`, or any text in `soft` (3.48:1 on paper). +- Gridlines, or a value axis that repeats numbers the endpoints already print. +- Annotating the crossing with a date, or reading any intermediate value off a slope. +- A `transform` on a series line, a bound label, an ancestor group, or in CSS — it moves the mark away from the checked coordinate. +- An unbound visible string: a name, a value or a state caption with no attribute stating the same thing. +- Curving the connector. There is nothing between the two points to curve through. + +### Ridgeline + +**Best for:** one **distribution** per series, stacked at a fixed pitch with deliberate overlap, when the shape of each distribution is the story and the series are directly comparable — request latency per service, build duration per pipeline, session length per cohort. The line chart above plots one value per x; a ridgeline plots a whole distribution per row, and the reading is the silhouette: where the mass sits, how tight it is, whether there is a second peak. A p50/p99 pair cannot show a bimodal service, and a box plot flattens it to a rectangle. + +Not for: a single distribution (that is a histogram — one ridge is a ridgeline with the comparison removed); series measured in different units or on different x-ranges, which cannot share the one x-scale the type requires; time series, where each row is one value per moment rather than one distribution; or distributions so similar that the ridges are five copies of one shape, which a table of percentiles says shorter. + +#### Layout conventions + +- **One baseline per ridge at a fixed pitch**, inside the `0 0 1000 500` viewBox the other Line variants use. The shipped example runs five baselines at `y` 152/208/264/320/376, a 56px pitch. +- **The x-run is the slopegraph's**, `x` 320 → 680, sampled at 13 bins 30px apart. The gutters are symmetric about it: names right-aligned ending at `x=304`, ranges starting at `x=696`, both 16px clear of the plot. +- **Name left of the baseline, range right of it**, each on its ridge's own row (`y = baseline + 3.5`). The range is the span of the ridge's nonzero mass in x-axis units, which is the number a silhouette cannot give you. +- **Bin ticks** in Geist Mono 9px at `y=400`, centred on bin positions and tracked `0.14em`, with the x-axis caption at `y=424`. The rotated amplitude caption sits at `x=24`, as in the parent chart. +- **Ridge count 3–12, bins 8–40.** Below three ridges there is no family of shapes to compare and two distributions are a pair of small multiples; past twelve the stack is taller than a reader can hold one silhouette in mind across. Below eight bins the outline is a histogram wearing a curve's clothes; past forty the bins are narrower than the noise in them. +- **Straight segments between bins, closed with `Z`.** Not splines: the source line states the drawing is unsmoothed, and a curve through binned counts puts extrema between bins that the sample never measured. The draft this variant came from permits Catmull-Rom with vertices on true values; the shipped grammar does not use it, because unsmoothed bins need no footnote about what the curve is allowed to invent. +- **No gridlines.** The baselines are the rules, and every ridge prints its own range. + +#### Colour + +The slopegraph's colour section holds here unchanged, with one addition for the fill. One accent on the editorially focal ridge (stroke `accent`, fill the accent at `0.16`), an `ink` opacity ramp for the rest (`0.80 → 0.62`, floor `0.53`) ordered top row to bottom, and focus carried by stroke weight — 2.4px against 1.2px — rather than tone. Labels stay `ink` (names) and `muted` (ranges) on every ridge including the focal one. + +- **Fill `ink` at `0.12` on every non-focal ridge**, low enough that two overlapping ridges read as depth rather than as a third tone. This is the one place the type needs a fill at all: the outline alone does not say which side of the curve is mass. +- **Legend wording stays skin-neutral** — "strongest tone", never "darkest". The ramp is ink-at-opacity, so its top is the darkest line on light paper and the lightest on dark, and a legend that says "darker" ships false in one of the two skins while rendering perfectly in both. +- **The accent marks the ridge the story is about, not the worst performer.** In the shipped example it marks the service whose *shape* is unusual, not the slowest one. + +#### Honest-data rule + +**One amplitude on every ridge, stated in the source line.** That is the entire claim of the type: the ridges are stacked so their silhouettes can be compared, and per-ridge normalisation destroys exactly that while rendering beautifully — a rare, flat distribution given its own scale wears the same shape as a tight one. A project-specific ridgeline verifier should derive the figure's single amplitude and hold every vertex of every ridge to it. + +- **The baseline never lies.** Each ridge declares the row it rises from, and that row must sit on the stack's fixed pitch with its rule drawn across the full bin run. A baseline nudged up to give one ridge headroom is the same falsification as a private amplitude, told with different arithmetic — and it is the harder one to see, because the silhouette above it is untouched. +- **Every ridge shares one x-scale.** A peak at one x means one latency on every row, or the column comparison the type exists for is fiction. +- **State the overlap, and keep it overlap.** Ridges are meant to intrude on the row above — that is how the stack reads as depth. A peak that reaches the row *two* above is occluded by the peaks it passes, and the fix is more pitch, never a smaller amplitude on one ridge. The checker enforces the ceiling; the source line states the amplitude so the reader can convert a height back into a number. +- **A ridge starts and ends on its own baseline.** The first and last bins are zero, so the outline closes along the baseline. A distribution clipped mid-mass draws a cliff, and a cliff reads as data. +- **No smoothing beyond what the footnote states.** The shipped grammar smooths nothing at all. If a figure ever does smooth, the footnote names the method and the vertices stay on true values — a spline that invents a second peak is indistinguishable, on the page, from a service that has one. +- **Height is share, not volume.** Each ridge is normalised to its own series' count before the shared amplitude is applied, so the tallest ridge is the most concentrated, not the busiest. Say so in the source line; a reader who assumes height is traffic reads the figure exactly backwards. + +#### Declaring the values + +The binding contract is the slopegraph's, applied to areas: the outline declares its bins and its baseline, and every visible string is bound to what it describes. + +```svg + + +checkout-api +40–440 ms +240 +``` + +`data-bins` is the basis of every geometric check, and it is this contract's own vocabulary: the slopegraph above binds `data-series` on a ``, this variant binds `data-bins` on a ``, and neither gate reads the other's attribute, so neither claims the other's file. Any further Line variant should take its own attribute for the same reason — a shared name means two checkers holding one figure to two contracts, and the one that loses rejects it for lacking elements it never said it had. `data-baseline` is what makes a moved row detectable; without it the checker would have to infer the zero from the drawing, which is the very thing being falsified. The printed range is cross-checked against the first and last nonzero bin through the figure's own tick scale, so a range widened by a word is a finding. A project-specific ridgeline verifier should cover the amplitude, the pitch, the baseline rules, the shared bins, the segment grammar, the overlap ceiling, the focus pairing, and every label binding. Its focused tests should prove each check in both polarities and pin the scope treaty with sibling gates. + +**No `transform` on any of it**, for the reason the slopegraph section gives: the checker reads raw coordinates, so a transform on an outline, a baseline rule, a bound label, an ancestor `` or a CSS rule moves the rendered mark away from the bin that was verified. The rotated amplitude caption is fine — it is neither verified geometry nor a bound label. + +#### Anti-patterns + +- Per-ridge normalisation, or any second amplitude anywhere in the figure — the type's one unforgivable error. +- A baseline moved off the pitch to buy one ridge headroom, or a baseline rule drawn somewhere other than the row its ridge declares. +- Ridges sampled on different x-ranges, or an x-scale that is not printed at all. +- Smoothing that puts a peak between two bins, and any spline in a figure whose footnote says the drawing is unsmoothed. +- A ridge clipped mid-mass so the outline closes as a cliff. +- Pitch so tight that peaks hide behind peaks — increase the pitch, never shrink one ridge. +- One hue per ridge instead of the ink ramp plus a single accent. +- A legend that says "darker is faster", which is false on one of the two skins. +- Fewer than 3 ridges (that is a histogram or a pair of small multiples) or more than 12. +- Reading traffic off ridge height, or shipping a figure whose source line lets a reader do so. + +### Bump chart + +**Best for:** rank movement across **3–6 ordered snapshots** when position, not magnitude, is the story — package popularity by quarter, team standings by sprint, top queries by month. The slopegraph above shows two moments and keeps magnitude; a bump chart trades magnitude away entirely to show *several* moments of pure position. That trade is the type: the vertical axis is rank, every row is one rank apart, and a flat line means "nothing displaced it", not "nothing changed". + +Not for: exactly two snapshots (that is the **slopegraph** above); magnitude stories — a series whose downloads doubled while its rank held draws a flat line, and if that surprise matters the reader needed a **line chart**; fewer than 4 series (a sentence is shorter) or more than 8 (spaghetti with a legend). + +#### Layout conventions + +- **One vertical axis rule per snapshot**, evenly pitched inside the plot, with the label gutters of the slopegraph: names right-aligned ending at `x=272` and first ranks at `x=304` on the left, mirrored from `x=696` (ranks) and `x=728` (names) on the right. The shipped example runs four axes at `x` 320/440/560/680 — the same 360px run as the slopegraph, spent in three segments instead of one. +- **Rank rows on a fixed pitch.** The shipped grid is `y = 88 + 56 × (rank − 1)`. Rank is ordinal, so — unlike the slopegraph, whose endpoint `y` values are data-scaled and grid-exempt — **every vertex lands exactly on the 4px grid**, and a project-specific bump-chart verifier should enforce the row placement with no tolerance at all. There is no honest reason for a vertex to sit off its row. +- **Straight segments between adjacent snapshots, dots at every vertex** (`r=3`, focal `r=4`). Never splines: a curve between two quarterly snapshots draws a trajectory nobody measured. The draft this variant came from calls them subway curves and bans them outright. +- **Labels at first and last appearance** — name and rank (`#1`…`#6`, the sigil keeps a rank from reading as a magnitude) at both ends, each on its own series' row **and in the gutter outboard of the end it names**. Both coordinates are required and both are checked: the row says which series a label belongs to, the column says which *end* of it, and neither implies the other. A first-end label slid along its row into the plot prints every rank correctly and reads against the wrong snapshot. +- **Snapshot captions** in Geist Mono 9px, centred under each axis, bound with `data-axis` / `data-state` exactly as the slopegraph binds its two. +- **Series count 4–8, snapshots 3–6.** Two snapshots are a slopegraph; past six the columns compress until rank changes cannot be followed. +- **No gridlines.** The dots are the readable positions and the axis rules are the columns. + +#### Colour + +Everything the slopegraph's colour section says holds here unchanged: one accent on the editorially focal series, an `ink` opacity ramp (`0.80 → 0.62`, floor 0.53) for the rest — ordered by first-snapshot rank, so the legend can say "strongest tone was highest-ranked", skin-neutrally — focus carried by stroke weight (2.4px against 1.2px) and dot size rather than tone, and labels in `ink`/`muted` on every series including the focal one. The accent marks the series the story is about, never the winner: the shipped example spends it on the package that *fell*. + +#### Honest-data rule + +**State the ranking key and the tie-break in the source line.** Rank hides magnitude by design, so the footnote is where a reader learns what "first" means and why no two series ever share a row. A project-specific bump-chart verifier should gate the geometry half: every snapshot's ranks must be a permutation of 1..N — a duplicated rank is a tie the stated tie-break cannot produce, and a skipped rank is an empty row the reader fills with a series that is not there. + +- **If the ranking measure changed definition between snapshots, the chart is invalid** — ranks under different measures are not comparable, and no drawing convention repairs that. +- **A series that enters late or leaves early starts or stops.** A real gap is drawn as absence, never interpolated across. The shipped grammar has no way to *declare* a gap yet, so a project-specific bump-chart verifier should require every series to visit every snapshot — a series with fewer vertices than columns is a finding until a gap declaration exists, because widening the rule without one would let a truncated series pass as a deliberate exit. +- **Never smooth a tie into a crossing.** The tie-break decides the order; drawing anything else invents a rank. +- **Never nudge a vertex off its row** to dodge a label collision — it reads as a rank between two ranks, and the checker treats it as the lie it is. + +#### Declaring the values + +The binding contract is the slopegraph's, one level up: the path declares its ranks, and every visible string is bound to what it describes. + +```svg + +legacy-http +#1 +Q1 +``` + +`data-ranks` is the basis of every geometric check, so a series whose labels go missing stays in the verified set and the missing label is itself reported. A project-specific bump-chart verifier should cover the grid, the permutations, the segments, the dots, the focus pairing, the label bindings, label placement on both axes, and the captions; focused bump-chart tests should prove each check in both polarities. The gutter x is read off the figure — every label sharing an end and a role must agree on one column — so a resized plot needs no constant changed here. + +## Examples + +- `assets/example-line.html` — minimal light +- `assets/example-line-dark.html` — minimal dark +- `assets/example-line-full.html` — full editorial +- `assets/example-slopegraph.html` — slopegraph, minimal light +- `assets/example-slopegraph-dark.html` — slopegraph, minimal dark +- `assets/example-slopegraph-full.html` — slopegraph, full editorial +- `assets/example-ridgeline.html` — ridgeline, minimal light +- `assets/example-ridgeline-dark.html` — ridgeline, minimal dark +- `assets/example-ridgeline-full.html` — ridgeline, full editorial +- `assets/example-bump.html` — bump chart, minimal light +- `assets/example-bump-dark.html` — bump chart, minimal dark +- `assets/example-bump-full.html` — bump chart, full editorial diff --git a/.agents/skills/diagram-design/references/type-loop.md b/.agents/skills/diagram-design/references/type-loop.md new file mode 100644 index 0000000000..aaf2bce0d9 --- /dev/null +++ b/.agents/skills/diagram-design/references/type-loop.md @@ -0,0 +1,223 @@ +# Loop + +**Best for:** reinforcing cycles, flywheels, feedback loops, and operating loops — anything where the last step feeds the first and a shared hub accumulates state.

Every segment uses the same center `C`, radius `R`, and clockwise sweep. The station boxes interrupt the circle; connectors begin at the circle's clockwise exit from the source box and end just before its counterclockwise entry into the destination box, so the marker tip lands on the destination stroke. + +Find the circle/rectangle intersections against all four edges of station `k`. For vertical edge `x = x_e`: + +```text +y = cy +/- sqrt(R^2 - (x_e - cx)^2) +``` + +Keep only candidates whose `y` lies within the edge.

The arrowhead overhang completes the final 1.2px to `q_entry(j)`, landing on the box edge without crossing its stroke. The closing connector from station `N-1` to station 0 uses the identical formula. + +Loop's circular ring arcs are a documented type-specific exception to SKILL.md §6 rule 1, following the same precedent as Medallion's promotion arcs.

The lighter arrowhead stops before the hub stroke instead of colliding with it. Radial spokes are the type-specific exception to the general ban on slanted straight connectors; they must remain true radii, must not cross one another, and may touch only their source station and the hub. + +Labels are optional when the station sublabel already names the write-back. When used, they follow the `arrow-label` role, stay to one side of the spoke, and receive an opaque `paper` mask with a visible 6–10px gap from the stroke. Label a curated subset rather than forcing six labels into the hub halo. + +### 2.4 ViewBox sizing + +The viewBox must include the full station rectangles, outer ring curves, arrowheads, and at least `margin` breathing room: + +```text +left <= cx - R - station_w/2 - margin +right >= cx + R + station_w/2 + margin +top <= cy - R - station_h/2 - margin +bottom >= cy + R + station_h/2 + margin + +viewBox_w = right - left +viewBox_h = bottom - top +``` + +Include the full circle extrema `cx +/- R`, `cy +/- R` plus station bounds and marker clearance when checking these limits.

Connector rules (mandatory) + +SKILL.md §6 applies in full except for the two Loop-specific connector primitives: circular ring arcs (§2.2) and straight radial spokes (§2.3). Like Medallion's promotion arcs, these replace §6 rule 1 for this diagram type: + +- Ring arrows are same-radius circular arcs, solid, and clockwise. Every path uses `A R R 0 0 1`; destination markers land on station edges and no connector ends at a center point. +- Spokes are dashed and point inward. A solid spoke destroys the visual distinction between operating flow and write-back. +- Labels use opaque masks and maintain a visible 6–10px connector gap. Never place text on the stroke. +- No ring connector or spoke may overlap another connector. Ring paths remain outside the hub; spokes occupy distinct radial routes. +- When two spokes must leave the same station edge, fan their attach points by the §6 formula with at least 12px separation.

Browsers and Playwright/Chromium render this faithfully; if your export target doesn't support `` (some older Inkscape builds), hand-split long values into two `` lines instead. + +Field labels use the `node-name` role at 11px in ink. Field values use the `sublabel` role in muted. Bucket and field values can be retinted by `color` override (§4). + +### 2.3 Tier styles + +Four canonical styles, picked per tier via `tiers[i].style`. Default mapping if `style` is omitted: tier 0 → `outer`, last tier → `cold`, focal tier (if any) → `focal`, others → `default`. + +| `style` | Card fill | Card stroke | Header band fill | Bucket text | Example value text | +|---|---|---|---|---|---| +| `outer` | `#FFFFFF` | `muted` 1.0 solid | `muted @ 0.10` | `muted` | `muted` | +| `default` | `#FFFFFF` | `ink` 1.0 solid | `ink @ 0.06` | `muted` | `muted` | +| `focal` | `accent @ 0.07` | `accent` 1.6 solid | `accent @ 0.14` | `accent` | `accent` | +| `cold` | `paper-2` | `muted` 1.0 dashed `5,3` | `muted @ 0.18` | `muted` | `muted` | + +`rx = 6` on all card rects. + +**Focal styling note:** the focal tier's accent treatment cascades — its bucket text and its example-value lines render in accent. Other field values (tool/format/writer) stay muted; only the bucket name and the example payload carry the focal signal so the tier card doesn't fully drown in coral. + +### 2.4 Promotion arcs (over the top of the tiers) + +Each promotion is a **cubic Bézier arc** anchored at the **top-center** of each adjacent tier — `(tier_cx(i), tier_y)` to `(tier_cx(i+1), tier_y)`. The arc rises into the 80-px `arc_band` above the cards, peaking at y ≈ 20. Both the connector and its label remain fully visible — no paper masks, no overlap with card content. + +```svg + +``` + +Concrete for the canonical 5-tier shape (`tier_y = 80`, tier centers at x = 102, 290, 478, 666, 854): +- 0→1: `M 102,80 C 102,0 290,0 290,80` +- 1→2: `M 290,80 C 290,0 478,0 478,80` +- 2→3: `M 478,80 C 478,0 666,0 666,80` (focal — accent) +- 3→4: `M 666,80 C 666,0 854,0 854,80` (lifecycle — dashed) + +The cubic geometry: anchor y = 80 (tier top), control y = 0 (top of viewBox). Curve peak at t=0.5 sits at y ≈ 20 (computed from `0.125·80 + 0.375·0 + 0.375·0 + 0.125·80 = 20`). Each arc spans one full tier-stride (188 px on the canonical layout), giving the connector a clearly visible vertical excursion. + +**Marker orientation:** `marker-end` with `orient="auto"` rotates the arrow to match the path tangent at the endpoint. The control point sits directly above the anchor so the tangent at landing is straight **down** — the arrowhead enters the top-center of tier *i+1* cleanly, pointing into the header band. + +**Chained anchors:** consecutive arcs share their meeting points (arc 0→1 ends at the same `(tier_cx(1), 80)` where arc 1→2 begins). Visually each tier's top-center acts as a "joint" — data arrives at the top of the card, gets transformed inside, and leaves out the top toward the next tier. The arrow-head plunge plus the next arc's straight-up emergence read as a single payload-handoff motion. + +| `style` | Stroke | Width | Dash | Marker | +|---|---|---|---|---| +| `normal` | `muted` | 1.4 | — | `arrow` | +| `focal` | `accent` | 1.6 | — | `arrow-accent` | +| `lifecycle` | `muted` | 1.4 | `4,3` | `arrow` | + +**Auto-style rules:** +- If `promotions[k].to` references the **focal tier**, the style auto-promotes to `focal` (accent, width 1.6, `arrow-accent` marker). +- If `promotions[k].to` references a tier with a **`color` override** (§4), the arrow inherits that hex — stroke = `C`, label fill = `C`, marker-end uses a color-matched marker (e.g., `arrow-yellow` for `#c9a23a`). Width stays at 1.4 — the color override is a "concern" signal, not a focal promotion. Lifecycle/dashed arrows keep their dash but adopt the color. +- Focal wins if both apply (a colored tier marked focal still uses accent). + +**Label inside the arc:** +- Anchored at `(arc_peak_x(k), arc_label_y)` = `((arc_src_x + arc_dst_x) / 2, 50)`. +- `arrow-label` role at 10px with `letter-spacing=0.08em`, uppercase. Color matches the arrow stroke. +- **No mask rect needed** — the cubic curve peaks at y ≈ 20 and the label sits at y=50, well below the curve. The label floats inside the open space *enclosed* by the arc, reading "X transforms into Y" with the arc itself as the visual frame. + +For shorter inter-tier gaps (if `tier_gap` is overridden below the default 16 px), the arc anchors `arc_inset` may need to shrink correspondingly to keep the arc visible. + +### 2.5 Path row (bottom, optional) + +Up to **2** write-method cards.

No more, no less — above 3 stages, split into two linked diagrams. +- **Nodes are vertical bars**, `width=12`, solid `ink` fill, no stroke. Height is proportional to the quantity passing through, rounded to the nearest 4px so it stays on-grid — the rounding is a rendering step, not a data change; the true value still prints in the quantity sublabel. +- **Flows are filled ribbons**, not stroked lines: a single closed `` per flow. Top edge is a cubic Bézier from the source node's top-offset to the target node's top-offset; bottom edge is the same curve run in reverse from target-bottom back to source-bottom. **Both** control points sit at the horizontal midpoint between the two columns, each at the y of the end it belongs to: `C midX,y0 midX,y1 targetX,y1`. That is what makes the band leave and arrive **horizontally**, so it plugs into each bar square-on. Putting the second control on the target's x instead (`C midX,y0 targetX,y1 targetX,y1`) collapses it onto the endpoint, the arrival tangent degenerates, and every ribbon meets its bar at a visible slant — it looks like the band is not attached. +- **No arrowheads, ever.** Direction is implied by the left-to-right column order. This is a deliberate, explicit exemption from SKILL.md §6's orthogonal-elbow-and-arrowhead rule: ribbons are area encodings, not connectors, and a marker on a filled band reads as clutter, not information. +- **Ribbon fill:** `muted` at `0.18` opacity for ordinary flows. The one editorial focal path (see below) uses `accent` at `0.28` opacity. A focal path may span more than one ribbon segment (e.g. two flows that both feed the same downstream node as halves of one story) — accenting every ribbon that belongs to that single path still counts as **one** focal element, not one per ribbon. Never per-flow rainbow coloring — color is reserved for the one path that deserves attention. +- **Node ordering minimizes crossings.** Order nodes within each column so that flows converging on (or diverging from) the same node stay in a consistent top-to-bottom sequence across columns. If two ribbons still cross more than once, reorder the nodes — don't let them tangle. +- **Labels:** node name in Geist sans 12px 600, quantity directly under it in Geist Mono 9px `muted`. Placement is column-specific: column 1 sits outside the bar, `text-anchor="end"`; column 2 sits in the gutter above its bar, `text-anchor="middle"`, **vertically centred in that gutter** rather than flush to the top, or the cap line grazes the bar above; column 3 sits outside the bar, `text-anchor="start"`. + + Centring the column-2 label in its gutter is what makes it legible: the gutter is the gap the bands themselves leave between two nodes, so a centred label sits on clean paper and needs no backing at all. Don't reach for a mask rect here — over a filled band it reads as a hole punched in the diagram, and if the label already sits on paper it is solving nothing. If a label genuinely has nowhere clear to sit, the column is over budget: drop a node or split the diagram. +- **Column headers:** Geist Mono 8px, uppercase, tracked, centered above each column — "CI COMPUTE BUDGET / TEST STAGE / OUTCOME" style eyebrows, not full sentences. +- **Drawing order:** background → column headers → ordinary ribbons → the accent path's ribbon(s) (painted last among ribbons so they read on top) → node bars → node labels → legend. +- **Legend:** horizontal strip at the bottom per the global rule, viewBox extended ~60–100px to fit it (a Sankey's ribbons need more bottom clearance than a typical diagram because node stacks run tall). Swatches are 16×8 rectangles matching each ribbon treatment, plus an optional italic aside stating the editorial read. + +## Scale rule + +Pick **one px-per-unit constant `k`** for the whole diagram and apply it to every node and ribbon thickness — never a different scale per column. Round each resulting thickness to the nearest 4px (grid compliance) and reconcile the rounding at the node level, not the flow level, so a node's outgoing ribbons still sum exactly to its (rounded) height. + +**When you control the numbers, choose ones that land on the grid.** At `k`, a 4px step is `4/k` units; pick quantities that are whole multiples of it and the drawn area is then exactly the printed number. Rounding is the fallback for real data you cannot choose, and it is a real cost: at `k = 0.02` a 4px step is 200 minutes, so a rounded bar can misstate its own label by up to 100. In a chart whose entire premise is that area encodes quantity, a bar that disagrees with the number printed beside it spends credibility to buy grid compliance. Never let the rounding exceed one 4px step, and never round a flow so far that a node's ribbons no longer sum to its bar. + +**Minimum rendered ribbon thickness: 4px.** Anything that would round to less gets folded into an "other" band rather than drawn as an invisible hairline — a Sankey ribbon the reader can't see isn't communicating anything. + +### Worked reference (k = 0.02 px/unit, budget = 12,000 CI minutes) + +| Node | Quantity | Height (px) | +|---|---|---| +| CI minutes (col 1) | 12,000 | 240 | +| Unit tests | 5,200 | 104 | +| E2E | 4,000 | 80 | +| Build | 2,000 | 40 | +| Lint | 800 | 16 | +| Passed | 9,400 | 188 | +| Failed | 1,600 | 32 | +| Flaked | 1,000 | 20 | + +Each column's node heights sum to the same 240px total — that invariant (total-in equals total-out) is what makes the diagram trustworthy at a glance.

A band arriving at an angle reads as detached from its node, which undermines the one thing the diagram is asserting — that this quantity flows into that node. +- **An opaque mask rect behind a column-2 label.** Over a filled band it reads as a hole punched in the diagram, and it erases any bar it overlaps. Centre the label in the gutter instead, where it sits on clean paper and needs nothing behind it. +- **Column-2 labels flush to the top of their gutter.** Centre them, or the cap line touches the bar above and the label looks like it belongs to the wrong node. +- **A bar whose height disagrees with the number printed beside it.** See the scale rule: choose grid-friendly quantities when the data is yours to choose. +- **Ribbons crossing more than once.** Reorder the nodes in the offending column; a Sankey with a tangle in the middle is unreadable. +- **Ribbons thinner than 4px.** Merge them into an "other" band instead of drawing a sliver no one can see. +- **Per-flow rainbow coloring.** One `muted` treatment for ordinary flows, one `accent` treatment for the flow that carries the editorial point — never a distinct hue per ribbon. +- **Using Sankey for a simple funnel.** A single narrowing quantity with no splits or merges is a pyramid/funnel, not a Sankey. +- **Using Sankey for a plain step sequence.** If nothing splits, merges, or varies in thickness, it's a process diagram — the whole point of Sankey is quantity that branches. +- **Stacking two flows at the same node-edge offset.** Every flow gets its own offset range within the node's height, in a consistent top-to-bottom order — never two ribbons overlapping at the same attach point. +- **Percentages or quantities that don't sum to the source total.** Every node's outgoing (or incoming) flows must sum to that node's own height.

This is ink-mass compensation, not an encoding: a giant bubble at the same opacity as a small one dominates the page by area alone, so opacity scales down as area scales up and every bubble ends up with comparable visual weight. Tone is **not** a fourth variable — the legend must say which end of the ramp is which, in skin-neutral terms ("faintest fill is the largest bubble" survives both skins; "darkest" ships false on one of them). +- **Every bubble keeps a `muted` stroke** (6.11:1 on light paper, 7.07:1 on dark) — the fills sit at opacities well under 3:1, so the stroke is what carries WCAG 1.4.11 for the mark's edge.
