A second binary (`prb`) is the operator CLI; a third +(`probod-bootstrap`) generates the YAML config from environment variables +inside the Docker entrypoint. + +The package layout is **flat by intention**: `pkg/probod` is the only +composition root, `pkg/probo` is the only domain-service layer +(`Service` → `Service.WithTenant` → `TenantService` with one sub-service +field per entity), and `pkg/coredata` is the only place SQL is allowed +to exist. Authorization is policy-as-Go-code in `pkg/iam/policy` with +policies registered at startup; resolvers (GraphQL and MCP) call +`r.authorize(ctx, id, action)` as their first line. Tenant isolation is +enforced by the `coredata.Scoper` injected into every query — see +[shared.md § 9](../shared.md#9-tenant-isolation--cross-stack-architectural-principle). + +The wiring philosophy is **constructor injection, no DI container**: every +service receives its dependencies as positional parameters from +`pkg/probod/probod.go:Run()`. Workers use `go.gearno.de/kit/worker` with +PostgreSQL `FOR UPDATE SKIP LOCKED` claim queries.

Now there is no way to distinguish +"don't change" (omit the field) from "set to null" (send null) — both +arrive as `nil`. + +**Why**: Single-pointer optional fields conflate two semantics. + +**Fix**: Use `**string` (or `**gid.GID`, `**time.Time`) on the update +request: + +```go +type UpdateVendorRequest struct { + Name *string // single ptr: nil = no change + Description **string // double ptr: outer nil = no change, outer non-nil + inner nil = set NULL +} +``` + +The validator framework auto-derefs both forms; the coredata Update +method understands both via its own check. + +**Source**: `pkg-probo.json` pitfall; canonical reference +`pkg/probo/vendor_service.go`. + +--- + +## 11. `pkg/probo` — 4-file checklist when adding a new entity + +**What goes wrong**: You add a new domain entity (`Asset` say), wire it +in `pkg/coredata`, write a service, expose a GraphQL field — and IAM +silently denies access for every role.

The Probo +adapter validates this client-side; OpenAI does not require it. + +**Fix**: Always populate `ChatCompletionRequest.MaxTokens` for any +request that may be routed to Anthropic. Default in +`pkg/probod/llm.go` is 4096. + +**Source**: `pkg-llm.json`; mapped errors in `pkg/llm/anthropic/provider.go`. + +--- + +## 13. `pkg/llm` streams — `stream.Close()` must always be called + +**What goes wrong**: A streaming call returns; the caller breaks out of +the loop on an early error and forgets to call `Close()`. The HTTP +connection leaks (held until socket timeout) and the OTel span never +ends. + +**Why**: `tracedStream` ends the span via `sync.Once` triggered by +either stream exhaustion **or** `Close()`. Skipping both leaks both. + +**Fix**: + +```go +stream, err := client.ChatCompletionStream(ctx, req) +if err != nil { return fmt.Errorf("cannot start stream: %w", err) } +defer stream.Close() // <-- mandatory + +for stream.Next() { ... } +if err := stream.Err(); err != nil { return err } +``` + +**Source**: `pkg-llm.json`; pattern in `pkg/llm/trace.go`. + +--- + +## 14. `pkg/webhook` — DTO discipline has no compile-time guard + +**What goes wrong**: `webhook.InsertData(ctx, tx, scope, orgID, "vendor:created", v)` +where `v` is a `*coredata.Vendor`. It compiles, runs, and the customer +receives a payload with internal field names (`tenant_id`, `db_*`), +deprecation-prone column names, and accidental sensitive fields. + +**Why**: `InsertData` accepts `any` for the payload and JSON-marshals +it. There is no type seam preventing coredata structs from leaking. + +**Fix**: Always wrap with `webhooktypes.NewXxx(coredata)`: + +```go +webhook.InsertData(ctx, tx, scope, orgID, "vendor:created", webhooktypes.NewVendor(v)) +``` + +If a DTO doesn't exist for a new entity, **add one** in +`pkg/webhook/types/.go` with a `NewXxx(coredata.Xxx) Xxx` +constructor. Reviewers enforce this — frequency-2 rule (PR #720). + +**Source**: `pkg-webhook.json`; review evidence +[shared.md § 13 #13](../shared.md#13-code-review-enforced-standards). + +--- + +## 15. `pkg/connector` — registering a new OAuth2 provider edits 3 maps + +**What goes wrong**: You add `LINEAR` to `providerDefinitions` but +forget to wire `ConnectorRegistry.Register("LINEAR", ...)` in +`pkg/probod/probod.go`, or you forget to expose the provider name in +the GraphQL/MCP enum. Either omission yields a runtime "unknown +provider" error. + +**Fix**: Three locations, lockstep: + +1. `pkg/connector/providers.go` — `providerDefinitions["LINEAR"] = {...}`. +2. `pkg/probod/probod.go` — call `Register("LINEAR", connector)` after + `ApplyProviderDefaults` with the deployment's client ID/secret. +3. The connector-provider GraphQL enum (and MCP equivalent) — add + `LINEAR` to keep the four-surface rule (see + [shared.md § 3](../shared.md#3-the-four-surface-api-rule)). + +**Source**: `pkg-connector.json` and `contrib/claude/api-surface.md`. + +--- + +## 16. `pkg/page` — `CursorKey.Value` is `any`, JSON round-trips can change `int` → `float64` + +**What goes wrong**: A cursor key is constructed with an +`int` sort value. After serialising to JSON and reading it back from +the client, the `Value` field is `float64`. Comparing +`reflect.DeepEqual(original, decoded)` fails, or worse, the +SQL parameter becomes a float and the keyset comparison silently +broadens. + +**Why**: `CursorKey` stores `any`, and Go's `encoding/json` +defaults all numbers to `float64` on decode. The base64-JSON round trip +inherits the loss. + +**Fix**: When parsing a cursor key from a client, normalise the value +to the expected concrete type before using it as a SQL parameter: + +```go +ck, err := page.ParseCursorKey(s) +// ... type-switch ck.Value to coerce float64 → int when expected ... +``` + +In practice, sort values are usually `time.Time` (passes through as +RFC3339 string) or `string`; the int trap appears with numeric sort +fields. + +**Source**: `pkg-page.json`. + +--- + +## 17. `pkg/probod` — `runTrustCenterServer` errgroup vs top-level WaitGroup + +**What goes wrong**: You "fix" the inconsistency by porting +`runTrustCenterServer` to the top-level `sync.WaitGroup` pattern. The +ACME provisioner can now run when the HTTP server has crashed, and +crash-fast semantics are lost. + +**Why**: The errgroup is **intentional** for this subsystem. The cert +provisioner, cert renewer, HTTP server, and HTTPS server form a unit: +if any of them dies, the others must die too. `errgroup.WithContext` +encodes that. + +**Fix**: Leave the errgroup in place. Document it locally if you touch +the file. Do not adopt errgroup at the top level — the rest of probod +deliberately separates child lifetimes. + +**Source**: `pkg-probod.json` pitfall. + +--- + +## 18. `cmd/` — adding a new binary requires three lockstep edits + +**What goes wrong**: You add `cmd/probo-migrate-thing/main.go`, build +locally, and ship. CI passes, the release pipeline runs, and the new +binary is missing from the release archives and the cross-platform +build matrix. + +**Why**: Three integration points outside the package: + +1. **`cmd//main.go`** itself. +2. **`GNUmakefile`** — append the binary to the build matrix and the + default `make build` target. +3. **GoReleaser CI config** — extend the build/archive entries so the + new binary is signed, packaged, and uploaded. + +**Fix**: Use an existing binary's diff (e.g. `probod-bootstrap`'s +introduction commit) as a checklist. See +[shared.md § 7](../shared.md#7-ci--quality-gates). + +**Source**: `cmd.json` open question. + +--- + +## 19. `pkg/iam/oidc`, `pkg/iam/oauth2server`, PKCE — 100% coverage required + +**What goes wrong**: A new helper in `pkg/iam/oidc/idtoken.go` ships +without unit tests.

The first INSERT panics at runtime (NoScope's +`GetTenantID()` panics), or — worse — a SELECT returns rows from every +tenant. + +**Why**: NoScope is a deliberate escape hatch for cross-tenant admin +queries (e.g. claiming the next pending row across all tenants). It +**panics** on `GetTenantID()` to prevent insert with no tenant. + +**Fix**: After claiming a tenant-owned row with NoScope, switch to +`coredata.NewScopeFromObjectID(row.ID)` for any subsequent +per-tenant work.

Always call the `*Ctx` variants + (`InfoCtx`, `WarnCtx`, `ErrorCtx`) so trace context propagates. Use typed field helpers + (`log.String`, `log.Int`, `log.Error`, `log.Duration`) — never `fmt.Sprintf` into the message. + Derive child loggers with `.Named()` at service boundaries and `.With()` for per-scope IDs. + Keep messages **static**; dynamic data goes in fields. +- **TypeScript** — `console.*` is acceptable for the SPAs (browser console). Apply the same PII + rules; redact tokens in dev tools output. Network errors should surface user-friendly messages + via the toast/notification system, not raw server responses. + +--- + +## 9. Tenant Isolation — Cross-Stack Architectural Principle + +> Source: [`contrib/claude/coredata.md`](../../contrib/claude/coredata.md), +> [`contrib/claude/gid.md`](../../contrib/claude/gid.md). + +Probo is multi-tenant. The isolation invariant is enforced at the **data layer**, not at the API +or UI layer: + +- The `tenant_id` column exists in **every** table but is **never** stored on a Go struct + (the **single exception is `Organization`**, which represents the tenant itself). +- `tenant_id` is injected at **query time** by the `Scoper` interface implemented by + `pkg/coredata`. Every SELECT, UPDATE, DELETE goes through a Scoper that adds the predicate. +- **Every** entity carries a denormalized `organization_id` column — used by + `AuthorizationAttributes()` for IAM checks without requiring JOINs (perf-critical). +- The **frontend trusts API responses**: the SPA does no tenant filtering of its own. If the API + returns it, the user is authorized to see it. UI must never silently filter rows by tenant. +- The CLI (`prb`) selects the active organization via a config file managed by `pkg/cli/config`; + the daemon enforces the actual scoping. + +**Rule for new tables / queries**: add `tenant_id BYTEA NOT NULL` and `organization_id BYTEA NOT NULL` +to every entity table, and route every read/write through a `Scoper`. `coredata.NewNoScope()` is a +deliberate escape hatch only for system-level operations and is reviewed (PR #957: +*"remove use coredata.NewNoScope() where needed"*). + +--- + +## 10.
