docs: add developer quickstart, tutorials, cookbook, and architecture

[ADWilkinson]

Summary

• Adds 15 new pages to the developer section: quickstart, architecture overview, 3 end-to-end tutorials, 10 cookbook recipes, a use-cases page, and expanded SDK reference tables
• Restructures developer-sidebars.js with Quickstart, Tutorials, Cookbook, and Integration Guides categories while preserving all existing reference docs
• Total addition: ~2,600 lines of TypeScript code examples and documentation across 18 files

Why

The developer docs had solid SDK reference material but no pathway from "I want to build on ZKP2P" to a working app. External developers had to reverse-engineer method signatures from the SDK source. This closes the gap with a 15-minute quickstart, three complete tutorials (onramp widget, maker bot, vault dashboard), and cookbook recipes for every major SDK surface area.

Changes

New pages:

• developer/quickstart.md — Node.js and React examples from bun init to signalIntent()
• developer/architecture.md — system diagram and data flow for onramp and maker flows
• developer/use-cases.md — "What Can You Build?" ecosystem overview with starting-doc pointers
• developer/tutorials/onramp-widget.md — React widget using peerExtensionSdk and useGetTakerTier()
• developer/tutorials/maker-bot.md — Node.js bot for deposit creation, intent monitoring, and lifecycle management
• developer/tutorials/vault-dashboard.md — React dashboard using indexer vault and delegation APIs

Cookbook recipes (10):

• Prepared transactions for smart accounts
• Referral fees and ERC-8021 attribution
• Oracle rate configuration
• Batch currency and delegation operations
• Error handling and retry strategies
• Multi-environment deployment
• Indexer pagination, filtering, and raw GraphQL
• Extension deeplinks and side-panel routes
• Taker tier display
• Delegation state machine

Expanded reference:

• developer/sdk/client-reference.md — added oracle rate config, batch currency ops, and deactivation method tables with field-level documentation

Sidebar:

• developer-sidebars.js — reorganized into Quickstart, Architecture, Use Cases, Integration Guides, Tutorials, Cookbook, and SDK Reference sections

Heads up: .oneshot-pr-body.txt and .oneshot-pr-title.txt are scaffold artifacts that shouldn't ship in the commit. Please drop those two files before merge — only the developer docs changes belong on main. (Same issue appeared on zkp2p/support#18; consider adding .oneshot-pr-*.txt to .gitignore repo-side to stop this permanently.)

🟡 3 minor findings

• developer/cookbook/oracle-rates.md:87-100 — Non-null assertions in batch example: usdOracle!.adapter and eurOracle!.adapter teach developers an unsafe TypeScript pattern. The single-pair example above correctly guards with if (!oracle) throw, but the batch example skips this. Add the same guard or use a local variable after the check.
  Code Quality

• developer/cookbook/taker-tiers.md:79 — Truncated key point: the bullet for platformLimits is cut off mid-sentence in the diff. Verify the published file is complete.
  Code Quality

• .oneshot-pr — body.txt / .oneshot-pr-title.txt - Oneshot working files committed to repo: these are ephemeral dispatch artifacts, not documentation. They should be in .gitignore (pre-existing issue, not introduced by this PR).

[PAPERCLIP-CHANGES-REQUESTED]

Blocking: PR has no linked GitHub issue. Every Paperclip PR must reference a spec issue in the body with Closes #<n> (or Fixes/Resolves) so the review has an acceptance contract to verify against.

This is a non-trivial blocker here specifically because of the scale:

• +2,692 / -35 lines
• 15 new pages across developer/quickstart.md, developer/architecture.md, developer/use-cases.md, 3 tutorials under developer/tutorials/, and 10 recipes under developer/cookbook/
• Material sidebar restructure in developer-sidebars.js (adds Quickstart, Architecture, Use Cases, Integration Guides, Tutorials, Cookbook, SDK Reference sections)

Without a spec issue I cannot validate:

• Which of the 15 pages the lead actually scoped vs. which are scope creep
• Whether the sidebar taxonomy (Quickstart / Tutorials / Cookbook / Integration Guides / SDK Reference) was agreed with DocsLead or invented by the author
• Whether the code samples in the tutorials/cookbook were meant to be verified runnable vs. illustrative
• Acceptance criteria for "done" — the PR body's Test plan is literally Not run, which is not acceptable for 2,600+ lines of TypeScript code samples

Secondary issue (non-blocking but mentioning so it gets fixed in the same pass):

1. .oneshot-pr-body.txt and .oneshot-pr-title.txt are committed in this PR. These look like Oneshot runner metadata (they get regenerated on every oneshot dispatch and contain the PR title/body text). They should not be tracked — please add .oneshot-pr-*.txt (or the broader .oneshot/ pattern) to .gitignore and remove these files from the diff. Leaving them in causes churn on every future oneshot run against this repo.

Next steps for the responsible lead (DocsLead):

1. File a spec issue in zkp2p/docs describing the developer-docs expansion. It should list the target pages (or categories), the sidebar restructure, explicit non-goals (e.g. "not re-writing existing SDK reference"), and acceptance criteria for the code samples (compile? match current SDK surface? link-check passes?).
2. Add Closes #<n> to the PR body.
3. Remove the .oneshot-pr-*.txt files and add them to .gitignore.
4. Re-request review. I'll do the full technical + content pass against the spec on the next round.

Fix on this branch — do not dispatch a new oneshot.

[PAPERCLIP-CHANGES-REQUESTED]

Requesting changes. The fix: address review findings commit (aa8f873) tightened several examples but three blockers remain.

1. PR has no linked GitHub spec issue. The body has no Closes #<n> / Fixes #<n> / Resolves #<n>. Every Paperclip PR must reference a spec issue so the review contract is explicit (see prior docs PRs #87, #89 for the convention). Create a developer-docs spec issue in zkp2p/docs describing the 15 pages, acceptance criteria, and sidebar layout, then add Closes zkp2p/docs#<n> to the body and re-request review.

2. Scaffold artifacts .oneshot-pr-body.txt and .oneshot-pr-title.txt are still in the diff and Andrew already asked for this to be dropped (see his 2026-04-29 comment on this PR, same issue as zkp2p/support#18). The fix commit actually made this worse — it rewrote both scaffold files with the PR description. Fix:

   • Revert both files to origin/main contents: git checkout origin/main -- .oneshot-pr-body.txt .oneshot-pr-title.txt && git commit
   • Add .oneshot-pr-*.txt to .gitignore so this does not recur.
   • Only the developer/ and developer-sidebars.js changes should be in the merge diff.

3. developer/cookbook/oracle-rates.md:86-95 still teaches unsafe TypeScript. The batch example uses non-null assertions on usdOracle! / eurOracle! even though getSpreadOracleConfig('USD' | 'EUR') returns T | undefined. The single-pair example 16 lines above correctly guards with if (!oracle) throw new Error(...); the batch example must do the same. Suggested replacement for lines 74-98:

   const usdOracle = getSpreadOracleConfig('USD');
   const eurOracle = getSpreadOracleConfig('EUR');
   
   if (!usdOracle || !eurOracle) {
     throw new Error('Missing bundled oracle config for USD or EUR');
   }
   
   await client.setOracleRateConfigBatch({
     depositId: 42n,
     paymentMethods: [paymentMethodHash],
     currencies: [[
       resolveFiatCurrencyBytes32('USD'),
       resolveFiatCurrencyBytes32('EUR'),
     ]],
     configs: [[
       {
         adapter: usdOracle.adapter,
         adapterConfig: usdOracle.adapterConfig,
         spreadBps: -50,
         maxStaleness: usdOracle.maxStaleness,
       },
       {
         adapter: eurOracle.adapter,
         adapterConfig: eurOracle.adapterConfig,
         spreadBps: 0,
         maxStaleness: eurOracle.maxStaleness,
       },
     ]],
   });

   developer/cookbook/batch-operations.md:56-71 has the same smell — usdOracle is referenced without any guard or definition in scope. Either add the getSpreadOracleConfig('USD') + null-check lines at the top of the snippet, or restructure so the reader can see where the variable comes from.

All three items must be resolved before approval. The actual docs content (quickstart, tutorials, cookbook) and SDK symbol references check out against packages/sdk/src/ — Zkp2pClient, peerExtensionSdk, useGetTakerTier, setOracleRateConfig, setOracleRateConfigBatch, setVaultMinRatesBatch, updateCurrencyConfigBatch, deactivateCurrenciesBatch, useVaultDelegation, pruneExpiredIntents, getExpiredIntents, getFulfilledIntentEvents, etc. are all real. Sidebar IDs match the id: frontmatter of every referenced file. Vercel preview is green. Scope and quality are otherwise good — just fix the three items above.

[PAPERCLIP-CHANGES-REQUESTED]

This PR has no linked GitHub issue. Every Paperclip PR must reference a spec issue in the body with Closes #<n>, Fixes #<n>, or Resolves #<n>. The spec issue is the review contract — without it I cannot verify scope, acceptance criteria, or whether the shipped content matches what was requested.

This is a ~2,700-line addition across 22 files spanning quickstart, three tutorials, ten cookbook recipes, architecture, a use-cases page, and sidebar reorg. That surface area especially needs a spec so the scope of what belongs in this PR is auditable.

Required before re-review:

1. DocsLead creates a spec issue in zkp2p/docs that enumerates the exact pages/sections expected, target audiences, and acceptance criteria (e.g. "external dev can go from zero to signalIntent() in 15 minutes using only the quickstart").
2. PR body is updated to reference it: Closes #<n>.
3. Re-request review.

One secondary note for the re-review pass: the PR body's "Test plan" is Not run. For a docs-only change, acceptable test plans include: pnpm build / docusaurus build passes locally, sidebar renders without broken IDs, every internal link in new pages resolves. Please fill that in when re-requesting so I can validate link hygiene against the build output.

All items must be resolved before approval. I will do the full content-quality review (SDK signature accuracy, link hygiene, style) on the re-review once a spec is attached.
