-# Basic rules
-- Never run a "dev" or "build" command, chances are I'm already running it in the background. Just ask me to check for updates or whatever you need
-- Never ever ever write a "TO DO" comment. If you've been told to do something, DO IT. Don't stop halfway. Never give up and just leave a "to do" comment and say - "haha heres working code :)" - that is unacceptible. Always finish your task, no matter how many iterations you need to perform.
-- DO NOT alter .gitignore
-- JS Doc comments should be SHORT and SWEET. Don't need examples unless ABSOLUTELY necessary
-- When using db schemas in Drizzle, import them from '@autumn/shared', and don't do schemas.
+<!-- Generated by ai-sync. Edit ai/rules/ instead. -->
 
-# Testing
-- When writing tests, ALWAYS read:
-  1. `server/tests/_guides/general-test-guide.md` - Common patterns, client initialization, public keys
-  2. Case-specific guide (e.g., `server/tests/_guides/check-endpoint-tests.md` for `/check` tests)
-- When running tests, ALL server-side console logs go to the server's logs which you do not have access to. You must ask the user to paste you in the logs, instead of expecting the server logs to magically appear
-in the test logs. Use your common sense
+# Scope Cache Refresh Changes Safely
 
-# Linting and Codebase rules
-- You can access the biome linter by running `bunx biome check <folder or file path>`. Always specify a folder path, as the codebase is quite large and you will get out of scope errors that you are not burdened to correct. If you would like to let biome automatically fix as much as it can, use  `bunx biome check --write <folder or file path>`
+When changing cache-refresh behavior for API routes:
 
-- Note, biome does not perform typechecking. For typechecks, either `cd` into the relevant workspace and run `bun ts`, or run `tsgo` directly. If you need to install it first, the npm package is `@typescript/native-preview`. Do not use `tsc` for workspace typechecks.
+- Prefer editing `server/src/honoMiddlewares/refreshCacheConfigs.ts` to add or remove route entries.
+- Do **not** remove or bypass logic in `server/src/honoMiddlewares/refreshCacheMiddleware.ts` unless the user explicitly asks to change middleware behavior globally.
+- If the request is ambiguous, ask whether they want a route-level config change or a global middleware behavior change.
 
-- The `server/src/_luaScriptsV2/` folder contains Lua scripts for Redis atomic operations. Redis uses **Lua 5.1** - there is NO `goto` statement (added in Lua 5.2), so use if/else blocks instead.
+# Cache Version Increment Policy
 
-- This codebase uses Bun as its preferred package manager and Node runtime.
+Treat `cache_version` as a DB-side stale-sync guard for `syncItemV4`, not a general cache mutation counter.
 
-- **ALWAYS import from `zod/v4`**, not from `zod` directly. Example: `import { z } from "zod/v4";`
+## Increment cache_version only when needed
 
-- Always prefer foo({ bar }) over foo(bar) method signatures - no matter if we are using only one argument or not, object as param are always better, as in the future when wanting to change the order of parameters, or add new ones - its easier.
+Increment only for DB updates that must not be overwritten by stale sync payloads read from cache (for example lifecycle or billing transitions).
 
-- When creating "hooks" folders, don't nest them under "components"
+## Do not increment on cache-side/runtime patch paths
 
-- Functions (unless there's a very good reason) should always take in objects as arguments. Object params are named and easy to understand.
+For runtime balance/reset/cache patch flows, do not bump `cache_version` in cache writers or Lua update scripts.
 
-- For regular functions, use inline object types in the function signature rather than creating separate type definitions. Only create named types when they're reused across multiple functions or exported.
-  ```typescript
-  // ❌ BAD - Unnecessary type definition for single-use params
-  type DoSomethingParams = {
-    ctx: AutumnContext;
-    customerId: string;
-  };
-  const doSomething = async ({ ctx, customerId }: DoSomethingParams) => { ... }
+Examples:
 
-  // ✅ GOOD - Inline object type
-  const doSomething = async ({ ctx, customerId }: { ctx: AutumnContext; customerId: string }) => { ... }
-  ```
+- FullSubject cache patch helpers (`updateSubjectBalanceCache`, reset/deduction cache patch sync helpers)
+- FullSubject Lua cache update scripts (`updateSubjectBalances`)
+- Update-balance runtime paths that patch Redis and then sync
 
-- This codebase uses Bun for all of its operations in `/server`, `/vite` and `/shared`. It uses Bun for the package management, Bun for the workspace management and Bun for the runtime. Prefer Bun over PNPM. If you ever want to trace a package dependency tree, run `bun why <package name>` which will tell you why a certain package was installed and by who.
-- Prefer Guard clauses "if(!admin) return;" over explicity "if(admin) do X;" Early returns are better
+## Call-site rule for CusEntService.update
 
-- If you need the TypeScript CLI directly, run `tsgo` itself (package: `@typescript/native-preview`), not `npx tsc`.
+When using `CusEntService.update(...)` in runtime FullSubject cache patch flows, set `incrementCacheVersion` explicitly.
 
-- **ALWAYS use `.meta()` for zod-openapi schema registration**, NOT `.openapi()`. Example: `ApiProductSchema.meta({ id: "Product" })`
+- Use `incrementCacheVersion: false` for routine balance/reset/adjustment updates that are mirrored to Redis.
+- Use `incrementCacheVersion: true` only for intentional DB-side stale-write protection transitions.
 
-- **ALWAYS use `c.req.param()` to get route parameters in Hono handlers**, NOT `c.req.valid("param")`. Example: `const { customer_id } = c.req.param();`
+## Why
 
-- When referring to a `customer_entitlement` object (or plural `customer_entitlements`), always use the full name. Do not abbreviate to "entitlement" or "entitlements" as this will be confused with the separate `entitlement` object.
+Incorrect version bumps create `CACHE_VERSION_MISMATCH` conflicts in `syncItemV4`, causing repeated invalidation and stale/lost update behavior.
 
-## Error Handling in API Routes
-- NEVER use `c.json({ message: "...", code: "..." }, statusCode)` pattern for input validation or expected errors in Hono routes
-- ALWAYS throw `RecaseError` from `@autumn/shared` for all validation errors, not found errors, forbidden errors, etc.
-- For internal/unexpected errors (like missing configuration, database errors, etc.), throw `InternalError` from `@autumn/shared`
-- The onError middleware automatically converts these errors to appropriate HTTP responses
-- Examples:
-  ```typescript
-  // ❌ BAD - Don't do this
-  if (!org) {
-    return c.json({ message: "Org not found", code: "not_found" }, 404);
-  }
+## Legacy exception (review-required)
 
-  // ✅ GOOD - Validation/expected errors use RecaseError
-  if (!org) {
-    throw new RecaseError({
-      message: "Org not found",
-      code: ErrCode.NotFound,
-      statusCode: 404,
-    });
-  }
+There is a legacy-compatibility exception in the adjust-balance flow:
 
-  // ✅ GOOD - Internal/unexpected errors use InternalError
-  if (!upstash) {
-    throw new InternalError({
-      message: "Upstash not configured",
-      code: "upstash_not_configured",
-    });
-  }
-  ```
+- `adjustBalanceDbAndCache` currently uses `CusEntService.increment/decrement`, which increments `cache_version`.
+- Treat this as a reviewable legacy action, not a pattern to copy into new runtime/cache patch paths.
+- Any new or refactored runtime balance/reset/cache patch code should continue following this policy and avoid adding new cache-version bumps by default.

+## Project Context System
 
-- Functions (unless there's a very good reason) should always take in objects as arguments. Object params are named and easy to understand.
+Projects maintain state in `.context/<project>/` folders across sessions. Tasks are optional parallel workstreams within a project.
 
-- This codebase uses Bun for all of its operations in `/server`, `/vite` and `/shared`. It uses Bun for the package management, Bun for the workspace management and Bun for the runtime. Prefer Bun over PNPM. If you ever want to trace a package dependency tree, run `bun why <package name>` which will tell you why a certain package was installed and by who.
+### Reading context (session start)
+When the user mentions a project or task name and `.context/<name>/` exists:
+1. Read project STATUS.md first (20-30 line "resume card")
+2. If the project has `tasks/`, list active tasks
+3. If the user mentions a specific task, read `tasks/<task>/STATUS.md`
+4. Read the most recent session summary if more detail is needed
+5. Do NOT read everything upfront. Use progressive disclosure.
 
-- Prefer Guard clauses "if(!admin) return;" over explicity "if(admin) do X;" Early returns are better
+### Updating context (at breakpoints, NOT continuously)
+Update at these moments ONLY:
+- Phase or milestone completed
+- Architectural decision made (append to DECISIONS.md)
+- User says they're done or switching tasks
+- Blocker discovered or resolved
+- Task created, completed, or handed off
 
+Do NOT update context during normal coding work. Work first, compact at breakpoints.
 
-# Figma MCP guidance
-- When you are using the Figma MCP server, you **must** follow our design system. Below is an example implementation of CVA with out design system
+### Compaction quality
+STATUS.md must be:
+- Correct (reflects actual current state, not stale)
+- Complete (no critical information missing)
+- Concise (project < 30 lines, task < 20 lines)
 
-## File Naming
-DON'T name files one word (like index.ts, model.ts, etc.). Give proper indication in the filename to which resource it's targeting. For example, a utility file for organizations should be named orgUtils.ts. This is because it's easier to search for files like this. That being said, the filename shouldn't be overly long (less than three words is ideal)
+Always REWRITE STATUS.md completely rather than append.
 
-# Vite
-## Components
-- Always use v2 components from `@/components/v2/` (buttons, inputs, dialogs, sheets, selects, etc.) for new features. Old components in `@/components/ui/` are deprecated.
+### File structure
+```
+.context/<project>/
+  STATUS.md       -- project resume card (includes Active Tasks section)
+  PLAN.md         -- phases and architecture
+  DECISIONS.md    -- append-only decision log
+  sessions/       -- dated session summaries
+  tasks/          -- optional parallel workstreams
+    <task>/
+      STATUS.md   -- task resume card
+      DECISIONS.md
+```
 
-## Sheets
-- Use `Sheet.tsx` for overlay sheets (modal-style with backdrop). Use `SheetHeader`, `SheetFooter`, `SheetSection` from `SharedSheetComponents.tsx` for consistent styling.
-- `InlineSheet.tsx` provides `SheetContainer` for inline sheets (embedded in page layout). It re-exports shared components for backwards compatibility.
-- Both sheet types support the same header/footer/section components, ensuring consistent UI patterns across overlay and inline implementations.
-
-## Styling
-- DO NOT hardcode styles when possible. Always try to reuse existing Tailwind classes or component patterns from similar components in the codebase.
-- When adding interactive elements (hover, focus, active states), look for existing patterns in similar components and reuse those class combinations.
-- Consistency is key - if a pattern exists, use it rather than creating a new one.
-
-## Form Elements
-- When creating form input elements (inputs, selects, textareas, etc.) in the vite folder, ALWAYS read `vite/FORM_DESIGN_GUIDELINES.md` first to understand the atomic CSS class system.
+### Task handoff
+When a task is being handed to another agent, ensure the task's STATUS.md is up to date -- it's the handoff artifact.

+  Lua Script: Update Subject Balances in V2 Cache (per-feature hash)
+
+  Atomically updates SubjectBalance entries in a single per-feature
+  balance hash. Each hash field is cusEntId -> JSON(SubjectBalance).
+
+  Supports: scalar field updates, rollover operations (insert/overwrite/delete),
+  replaceable operations (insert/delete), and an expected_next_reset_at guard.
+  This script intentionally does not increment or overwrite cache_version.
+  cache_version is owned by DB-side lifecycle/billing transitions.
+
+  After applying updates, propagates entity-level balance/adjustment deltas
+  to the _aggregated field on the same hash via update_aggregated_balances.
+
+  Helper functions prepended via string interpolation from:
+    - luaUtils.lua (safe_number, is_nil, safe_table)
+    - updateContextUtils.lua (init_update_context)
+    - applyFieldUpdates.lua (per-field update helpers)
+    - updateAggregatedBalances.lua (shared aggregation utility)
