[`apply_defaults`] runs first (insert-only, create only), then +//! [`apply_computed`], then [`check_requires`].

The CEL evaluator is deliberately **pure**: it has no I/O and no ambient +//! authority, so it does *not* expose a `now()` function (a wall-clock read +//! would be a side effect). Instead, every rule call takes a single +//! `now: DateTime` instant captured once by the handler, and +//! [`build_bindings`] binds it as a CEL variable named **`now`** (a +//! `timestamp`). Expressions therefore spell the current time as the variable +//! `now`, not as a call `now()` — e.g. `@default("now")` or +//! `@require("due_date >= now", "...")`.

This oracle is introduced in +issue #90 and currently gates approximately 2 123 workspace tests. + +The `cel` crate (upstream) is not depended upon, vendored, or referenced at +runtime. Cedar continues to serve only authorization; its scope does not expand. + +## Consequences + +- The `schema-forge-cel` crate is wholly owned by this project. There is no + upstream to track, no vendored snapshot to audit on every update, and no + transitive dependency that could surface as a supply-chain finding during ATO + review. +- The engine builds and runs with no runtime network access and no dependency on + non-FIPS primitives, satisfying airgap and FIPS environment requirements. +- Conformance is durable: the cel-spec corpus (issue #90) is a permanent + regression gate. Any future engine change that breaks a conformance case will + fail CI before it merges. +- Full ownership means the project carries maintenance. There is no upstream to + pull bug-fixes or new CEL spec features from; those must be implemented + in-house when needed. This is an accepted cost given the supply-chain and + auditability benefits. +- The decision is **already in effect**: issues #107, #108, and #109 are + complete. This ADR records the substrate context that informs the downstream + type-projection decisions in issue #98 (uint, ADR-0001) and issue #102. +- Because the conformance corpus is a test-time oracle and not a shipped + artifact, it imposes no runtime or distribution constraint. + +## Alternatives considered + +- **Live upstream dependency on the `cel` crate.** Rejected. The crate has been + effectively unmaintained since 2023, carries no conformance gate, and an + unvetted, unmaintained transitive dependency is an explicit audit liability for + a federal product seeking ATO. Supply-chain posture alone is disqualifying, + independent of any feature gaps. + +- **Vendoring the `cel` crate.** Rejected. Vendoring a snapshot would require + fully vetting the crate's existing design, gaps, and code at intake, and + re-vetting on every update. It would also mean inheriting a design that does + not naturally fit `DynamicValue`. Building exactly what SchemaForge needs from + scratch is cleaner: the scope is bounded, the shape is right-fitted, and there + is no inherited debt to audit. The effort to vet a vendored snapshot is not + materially less than building a purpose-fit implementation. + +- **Cedar for expression evaluation.** Hard no. Cedar is scoped to authorization + policy and produces boolean decisions; it does not evaluate expressions to + typed values. Overloading Cedar for expression evaluation would conflate two + distinct concerns (authz vs. data-layer predicate evaluation), complicate the + Cedar policy model, and produce an architecture that is difficult to explain + and audit.

Canonical write-path ordering (issue #105) + +For every entity create, update (PUT), and patch (PATCH), the engine executes a +single, fixed, engine-controlled sequence. The order does not depend on schema +authoring or on field declaration order across phases: + +```text +@default → @compute → @require → before_* hooks → PERSIST → { after_* hooks, webhook dispatch } +└───────────── rule phases (in-transaction) ─────────┘ └ network ┘ └────────── detached fan-out ──────────┘ +``` + +The three rule phases live in `crates/schema-forge-acton/src/rules.rs` +(`apply_defaults`, `apply_computed`, `check_requires`); the route handlers in +`crates/schema-forge-acton/src/routes/entities.rs` call them in this order +before dispatching any `before_*` hook. + +### 1.1 Why rules run before hooks + +The rule phases are **pure and cheap**: they evaluate CEL against the in-memory +field set with no I/O. Running them first means a `@require` rejection +short-circuits the entire write **before** any `before_*` gRPC hook network +round-trip and **before** anything is persisted. A request that violates a rule +never costs a hook call. + +### 1.2 The invariants + +| Invariant | Guarantee | +|---|---| +| In-transaction, pre-persistence | All three rule phases run before the backend write, inside the same request that persists. | +| Rules ahead of `before_*` hooks | `@default`/`@compute`/`@require` all complete before the first `before_*` hook is dispatched. | +| Deterministic, no reentrancy | Phases run in the fixed order above; each visits fields in schema declaration order; a phase never re-invokes an earlier phase. | +| Rejection suppresses all downstream work | A `@require` failure returns **422** and fires **no** `before_*` hook, persists **nothing**, and therefore fires **no** `after_*` hook and **no** webhook. | +| Fan-out is detached | `after_*` hooks (via the `HookDispatchActor`) and webhook delivery (spawned by the webhook dispatcher) never block the API response. | + +### 1.3 Phase notes + +- **`@default`** is *insert-only* — it runs on create only, never on PUT/PATCH, + and only fills a field that is absent or explicitly `null`. On create it runs + *after* the engine stamps owner/tenant/audit columns, so those injected + non-null values win over an expression `@default` for the same field. +- **`@compute`** is server-derived and **overwrites** any client-supplied value + for the computed field. It rebuilds its CEL bindings from the current field + map before each field, so a later compute can read an earlier one (chaining). + Because it runs after `@default`, a compute can read a defaulted sibling. +- **`@require`** runs last, so its predicates validate the *finalized* field set + — including computed values. It is **fail-closed**: a predicate passes only on + `Ok(true)`; a definite `false` is a 422 rejection, and an error or non-boolean + result is a 500 (a broken predicate can never let a write through). + +This ordering is proven by integration tests: +`rule_phase_order_default_then_compute_then_require_is_observable` (in +`crates/schema-forge-acton/tests/integration.rs`) and +`require_rejection_fires_no_before_or_after_hook_and_persists_nothing` / +`passing_require_reaches_before_and_after_hooks` (in +`crates/schema-forge-acton/tests/hooks_integration.rs`). + +## 2. Rules as part of the signed artifact (issue #106) + +A SchemaForge rule is **declarative annotation text inside the `.schema` +file** — for example: + +```text +schema Invoice { + @default("0") + subtotal: float + @compute("subtotal * 1.1") + total: float + @require("total >= 0", "total must be non-negative") + status: text +} +``` + +This is the audit win over an out-of-band gRPC hook: a hook's logic lives in a +separately-deployed binary that the schema signature does not cover, whereas a +rule's logic is bytes in the signed `.schema` file. + +### 2.1 How the signature covers the rules + +Signed-schema enforcement (see the [Signing Reference](signing-reference.md)) +binds the **raw bytes** of each `.schema` file to a signer: + +1. `schema-forge-signing` computes `sha256(file_bytes)` over the entire `.schema` + file and pins it in `schemas.manifest.toml`. +2. A per-file `.schema.sig` signs those same raw bytes. +3. On load under `mode = "warn"` / `"enforce"`, the verifier + (`VerifyPolicy::verify_files`) re-reads each file, recomputes the hash, checks + it against the manifest, and verifies the signature against the trust policy. + +Because the `@default` / `@compute` / `@require` annotation text is part of those +raw bytes, **any change to a rule expression changes the file hash and the +signature no longer matches**. An attacker who weakens a `@require` threshold +(say, `total >= 0` → `total >= -999999`) cannot do so without invalidating the +signature, and under `enforce` the load aborts (exit code 13). This is covered by +`enforce_mode_rejects_tampered_rule_annotation` in +`crates/schema-forge-signing/src/policy.rs`. + +### 2.2 How a reviewer enumerates every rule gating an entity + +The rules that gate an entity are exactly the `@default` / `@compute` / +`@require` annotations on that entity's fields in its signed `.schema` file. To +enumerate them with provenance: + +1. **Read the rules.** Open the signed `.schema` file (in the PR diff or on + disk). Every gating rule is a `@require` (rejects writes), `@compute` + (server-derived value), or `@default` (insert-time seed) annotation. There are + no hidden rules — there is no rule source other than the `.schema` text. +2. **Surface them mechanically.** `sf parse ` parses the `.schema` files and + reports the typed schema, including the annotations, so a reviewer does not + have to eyeball raw text. (`sf parse` also runs the verifier under the + configured mode, so a tampered file is reported there too.) +3. **Confirm provenance.** `sf verify` (or any load under `enforce`) checks the + per-file signature and manifest hash against the trust bundle. A passing + verification means the rules the reviewer just read are the exact rules that + will run — signed by a trusted identity, unmodified since. + +The pairing is the point: step 1–2 tell the reviewer *what* the rules are, and +step 3 gives them cryptographic assurance that *those* rules — not a tampered +variant — are what the running server enforces. + +## 3. Cross-entity reads in `@require` — `related..` (issue #95) + +A `@require` predicate may read a **single, committed, tenant-scoped related +row** through the reserved root identifier `related`. This is the only way a rule +reaches outside the row being written. + +```text +schema Document { + approval: -> Approval // a Relation{One} field; stores an opaque id (#102) + status: enum("draft", "closed") + @require("status != 'closed' || related.approval.state == 'granted'", + "closed documents need a granted approval") +} +``` + +`approval` (the bare field) is the opaque id string (#102 projection, unchanged). +`related.approval` is the **dereferenced** `Approval` row, bound as a CEL map; +`.state` is a column on it. The mandatory `related.` prefix makes every +cross-entity read explicit and greppable in the schema text — an audit +requirement. + +### 3.1 The hard limits (v1) + +| Limit | Rule | Where enforced | +|-------|------|----------------| +| Single `Relation{One}` only | `related.F` requires `F` to be a declared `Relation{One}` field. `Relation{Many}` (to-many) → rejected; non-relation / undeclared → rejected. | DSL apply-time (`check_rule_types`); runtime resolver defensively re-checks. | +| `@require` only | `related.*` in `@compute` / `@default` is rejected (persisting a copy of another row's field is a staleness trap that belongs in a hook). | DSL apply-time. | +| Single hop only | `related.F.G.<…>` where `G` is itself a `Relation` on `F`'s target schema is rejected with a clear multi-hop error. | Runtime resolver (it holds every target schema via the batch fetch). | + +### 3.2 The engine stays pure — prefetch-and-bind + +The CEL evaluator (`schema-forge-cel`) is unchanged: **no backend handle, no +async, no I/O inside `evaluate`**. `schema_forge_cel::evaluate`'s signature is +untouched. Cross-entity reads work by the **same** mechanism the request clock +`now` uses: the route layer resolves the I/O **before** evaluation and injects +the result as a CEL binding. + +1. A pure AST walker (`schema_forge_cel::related_paths`) extracts every + `related..<…>` path from a `@require` expression. +2. The route handler + (`check_requires_with_related` in `routes/entities.rs`) collects the distinct + `Relation{One}` fields referenced, reads each FK id from the in-flight field + map, loads the related row through the supervised `forge` actor, projects it + with `dynamic_to_cel` (#102 projection — the target's own relations stay + opaque id strings), and assembles a `related` map: `{ F -> row_map, … }`. +3. That map is inserted into the `Bindings` next to `principal` and `now`, then + the **pure** `check_requires_with_bindings` evaluates the predicate. + +### 3.3 Tenant scope and fail-closed + +The related row is loaded through the **same** tenant-scoped query path the read +endpoints use (`inject_tenant_scope` + a `Filter::In { id }` query via the +supervised `forge` actor — *not* the unscoped `GetEntity`). A rule therefore can +**never** read a related row across a tenant boundary the caller couldn't +otherwise see. + +The contract is **fail-closed**. If the FK is absent/null, the related row does +not exist, or tenant scope hides it, the `related.F` entry is simply **not +bound**. A `@require` that then references `related.F` hits an absent reference, +and the existing fail-closed contract in `check_requires` turns that into a +rejection / eval-error — **never a silent pass and never a null-coerced value**. +This is covered end-to-end by `crates/schema-forge-acton/tests/cross_entity_reads.rs`. diff --git a/docs/site-guide.md b/docs/site-guide.md index bb18b62..55d0a12 100644 --- a/docs/site-guide.md +++ b/docs/site-guide.md @@ -112,6 +112,17 @@ pnpm preview # local sanity check of the production build | `relation Many` (derived inverse, issue #34) | *rendered as a read-only linked list on the detail page* | The backend rejects writes on derived collections, so the generator skips them on create/edit forms and their zod schemas (issue #35).
