Fix: harden billing engine, auth middleware, and request throttling - #13
Conversation
- Billing Engine: Fix start-value resolution to correctly skip draft and empty periods using innerJoin - Auth & Access: Handle 403 Forbidden responses in api-client to redirect unverified users to /verify-email - Add middleware unit tests covering unverified-user redirects - Edit Requests: Check throttle limits before cancelling existing requests, allowing same-period overwrites without cross-period spam - Add strict Zod validation for proposedValues in approval and rejection flows - Bills: Fix the markPaidRoute race condition by reading tenancyId directly from the base bill - Validation & UI: Update parseDateInput to reject out-of-range calendar dates such as February 30 - Guard against invalid solarActivatedAt timestamps in PropertySettings.tsx - Documentation: Redesign the README.md Shield-style badges - Update DEPLOY.md with a deployment rollback guide - Update AGENTS.md DOX contracts to reflect the new architectural rules
📝 WalkthroughWalkthroughThe change adds deployment documentation, updates billing and edit-request behavior, improves paid-bill fallbacks, hardens API and date parsing, adjusts PDF runtime checks, and expands related test coverage. ChangesMeterly functional and operational updates
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The PR currently risks exposing production storage during remote development, allowing concurrent request submissions to bypass throttling limits, and reporting bills as paid after they have been deleted. Its rollback instructions also contain commands that would fail or be misparsed, so these issues should be fixed before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

💡 Result:
The wrangler d1 time-travel command is used to inspect or restore a Cloudflare D1 database to a previous point in time [1][2]. These commands act on remote D1 databases [1][3]. There are two primary subcommands for time travel: 1. d1 time-travel info: Retrieves information about a database at a specific point in time [1][2]. - Usage: npx wrangler d1 time-travel info [DATABASE_NAME] [OPTIONS] [1][2] - Options include --timestamp (to specify a Unix timestamp or RFC3339 string within the last 30 days) and --json [1][2]. 2. d1 time-travel restore: Restores a database to a specific point in time [2][4]. - Usage: npx wrangler d1 time-travel restore [DATABASE_NAME] [OPTIONS] [2][4] - Options include --bookmark (a specific D1 bookmark), --timestamp (a Unix timestamp or RFC3339 string within the last 30 days), and --json [1][2]. These commands are available in Wrangler and function on remote D1 databases [1][3].

Check canvas usability before enabling the smoke suite.
typeof HTMLCanvasElement !== "undefined" only checks constructor presence. A partial environment can pass all three checks while providing no usable 2D context, which can fail during PDF rendering. Probe a usable canvas context or gate the suite on a browser runner.

Cloudflare Wrangler configuration preview_bucket_name r2_buckets wrangler dev --remote behavior
💡 Result:
In Cloudflare Wrangler, preview_bucket_name and r2_buckets configurations manage how your Workers interact with R2 storage during local development and remote sessions [1]. R2 Buckets Configuration The r2_buckets setting is an array used to bind R2 buckets to your Worker [1][2]. - binding: The variable name used in your Worker code to access the bucket (e.g., env.MY_BUCKET) [2][3]. - bucket_name: The name of the production R2 bucket [1][2]. - preview_bucket_name: An optional configuration that specifies which R2 bucket to use during wrangler dev --remote [1]. Behavior of wrangler dev --remote When you run wrangler dev --remote, Wrangler proxies your requests to Cloudflare's infrastructure rather than simulating them locally [4][5]. - If preview_bucket_name is defined, your Worker will interact with that specific R2 bucket during the remote development session [1][5]. - If preview_bucket_name is omitted, the default bucket_name is used instead [1]. Note that using the production bucket for development carries the risk of modifying production data [5][6]. - The preview_bucket_name field is specifically required when using wrangler dev --remote if you wish to target a separate bucket for testing [1]. Local vs. Remote Behavior - Default Local Mode: By default, wrangler dev simulates bindings locally using an in-memory or file-based system [7][8]. It does not interface with actual R2 buckets on Cloudflare's network [9][6]. - Remote Bindings (Public Beta): As of June 2025, Cloudflare introduced a public beta for remote bindings [10]. By adding experimental_remote: true to a binding in your wrangler.toml or wrangler.jsonc, you can connect to real remote R2 buckets while running your Worker code locally [10]. This avoids the need for a full --remote dev session and allows you to test against production or staging data without deploying [10]. Configuration Example (wrangler.toml) [[r2_buckets]] binding = "MY_BUCKET" bucket_name = "my-production-bucket" preview_bucket_name = "my-dev-bucket" For remote development sessions via wrangler dev --remote, the my-dev-bucket will be bound to MY_BUCKET [1][11]. If you opt into the remote bindings beta for local execution, you would add experimental_remote = true to this configuration [10].

Update the active Wrangler configuration.
wrangler.jsonc sets preview_bucket_name to meterly-bills, so wrangler dev --remote uses the production R2 bucket. Set it to meterly-bills-preview and create that bucket.

In `@wrangler.jsonc.example` at line 24, Update the active Wrangler
configuration’s preview_bucket_name to meterly-bills-preview, matching the
example configuration, and create the corresponding R2 bucket so wrangler dev
--remote uses the preview bucket.
