The branch is kept as a reference under +`prototype/python-sdk-tracer`. **Do not merge it.** Read this file, then +CIP-4340, then start again from `main`. + +The code is disposable. What follows is not: it is what the code proved, +and most of it would take days to rediscover. + +## What was proven, live + +Against ZeroKMS (through the `stash auth login` profile) and a Postgres with +EQL v3.0.6 applied — 53 tests green, 3 Rust unit tests green: + +1. `import stackencrypt` from an `abi3-py39` wheel built by maturin over + `stack-encrypt`, in a fourth Cargo workspace at `languages/python`. +2. `Plan.of(User).context("users").build()` reads `Annotated` hints into the + engine's data plan, fails closed at `build()` on an undeclared field + (import time when that call sits at module level — by convention, not by + construction; see "Gaps against CIP-4340's wording"), and the engine's + own `plan_with` validates the rest with no credentials. +3. `Cipher(plan).encrypt(models)` seals a batch in **one** ZeroKMS request; + an empty batch makes none; `decrypt` returns the model type; `query` + returns a term. +4. **Byte parity with Rust**, produced at test time: the shell opens what + Rust sealed, Rust opens what the shell sealed, and the equality term is + byte-identical. +5. **The whole six-step path through PostgreSQL**: insert into + `public.eql_v3_text_eq`, equality query through `eql_v3.query_text_eq`, + read back, decrypt. This is the "TextEq proven end to end in PostgreSQL" + that the catalog's storage-only `Text` domain records as its own blocker. + +Not done: CI (Task 8) and the scorecard (Task 9). + +## Findings about the engine and the catalog + +These are facts about `main` as of 2026-10-13, independent of any Python +design choice. + +- **`stack-encrypt`'s `dynamic` feature is the entire binding surface, and + it is off by default.** `stack_encrypt::dynamic::record` — the data plan, + `FfiValue`, `plan_with`, `encrypt_with`, `decrypt_with`, `query` — does not + exist without it. `eql-bindings`' own `stack-encrypt` feature takes the + crate with `default-features = false` and does **not** enable it; the + binding crate must. `http` (credential discovery) is a default and should + be named explicitly so it cannot be dropped silently. +- **The catalog produces exactly one EQL type: `TextEq`.** Every other entry + resolves `Unproducible`, with four recorded reasons: 42 types because + "how this family encodes a plaintext for the stack-encrypt producer + profile is not specified; only the text family's encoding is"; `TextMatch` + and the `Ope` types because "the engine derives match and OPE terms, but + no EQL type is built from them yet"; the ORE types because "EQL stores a + block ORE term and the engine derives a CLLW ORE term; the two are + different algorithms"; `Text` because it "follows once TextEq is proven + end to end in PostgreSQL". **Consequence for CIP-4340:** decision 9 lists + `equality`, `match`, `ore` as the engine features the four tasks need, and + backlog item 5 is "`match` and `ore` queries". Neither is a Python change; + both wait on the engine. Amend the ticket before anyone builds against it. +- **The engine-side design for that gap already exists:** "Value encodings + for new EQL kinds" (7 Oct 2026, the same day as CIP-4340's decisions; + https://claude.ai/artifact/9JQR2Zwn7ft5QkyzrMurbh — a Claude + Docs draft for team review, "nothing is built or ticketed yet"; it is a + living document, so open the link rather than trusting a copy). Read it + before planning anything past `TextEq`. + What it establishes: + - The 42 non-text families are tracked in **#1130** and are "blocked on + encoding, not on code". A kind must exist in **three** encodings owned + by three crates — the ciphertext tag (`vitaminc-aead-value`), the + equality domain (`vitaminc-prf`), the order encoding (`cllw-ore` / + `ore-rs`) — and today they disagree about which types exist (`i16` is in + two of three, so it cannot be a kind). + - The ORE refusal is **#1132**: EQL v3 stores **block ORE** for the + `_ord_ore` domains and **CLLW OPE** for `_ord` / `_ord_ope`; Stack + Encrypt derives CLLW ORE and CLLW OPE and no block ORE. That is why + `TextOrdOre` is refused although text is a kind. + - The proposal: a `vitaminc-ore` crate with one order-preserving plaintext + encoding (adopting `orderable-bytes`) and pluggable schemes (block ORE, + CLLW ORE, CLLW OPE); new kinds `Int16`, `Date`, `Timestamp`, `Decimal` + with new frozen tags from `0x0C`; a conformance test that fails unless + every kind has all three encodings. + - It does **not** cover `TextMatch`, whose blocker is different ("the + engine derives match terms, but no EQL type is built from them yet"). + So `match` is a smaller, separate, unticketed piece of work; `ore` is + this proposal. + - **It reaches Python directly.** The kind table is "a cross-language + commitment", and every new kind means a codec "in each binding": when + `Int16` / `Date` / `Timestamp` / `Decimal` land, the shell's + `convert.rs` grows an arm each, the width markers gain four names, and + `Date` versus `Timestamp` is the same declaration ambiguity it already + flags for Go's `time.Time`. The restart's declaration shape should + leave room for that rather than hard-code today's nine scalar kinds. +- **The engine core does more than the catalog.** Through the bare-outputs + path (`"outputs": ["c", "match"]`) it seals any kind and derives `eq`, + `match`, `ore`, `ope`. What is `TextEq`-only is the *framing* into an EQL + v3 column type, which is `eql-bindings`' catalog, not the engine. +- **`"type"` is required on every field with a term output** (#1096, now on + `main`), and `admits` decides which kinds an index accepts: `Equality` + takes the integer kinds, `string`, `bytes`; `Match` takes `string` only; + `Ore`/`Ope` take anything but arrays and objects. Kind names are + vitaminc's lowercase vocabulary (`string`, `int64`, `float64`, `bool`…), + parsed with `ValueKind: FromStr`; use that parser, never a table. +- **A stored record is a `CipherText` tree, not bytes.** Per row a `Map`; + per field a `Map` keyed by output: a target field's EQL JSON rides as a + passthrough `FfiValue::Bytes` under `"eql"`, a passthrough field's value + as a passthrough `FfiValue` under `"passthrough"`, a ciphertext as a + sealed subtree under `"c"`. The first two extract directly to column + values; the third needs a tree codec (the Go host has one). The tracer + refused bare-`"c"` fields by name and lost nothing. +- **Ciphertexts are never byte-equal** (fresh IV per seal). "The bytes + agree" can only mean the deterministic equality term; the ciphertext is + proven by cross-opening. +- **The EQL identifier `i` is stamped from the plan's context** at encrypt + time — `{"t": "", "c": ""}` — and is + authenticated into the ciphertext. `.context("")` and the SQL + table should be the same word. Postgres does not check it. +- **Credentials:** `StackCipher::new()` → `AutoStrategy`: `CS_CLIENT_ACCESS_KEY` + + `CS_WORKSPACE_CRN` (`auto_strategy.rs:120`), else the device session in + `~/.cipherstash//auth.json` (`:129-133`); the client + key likewise from `CS_CLIENT_ID`/`CS_CLIENT_KEY` or `secretkey.json`. A + logged-in developer machine needs nothing set. **Any committed bytes + keyed to a workspace keyset (equality terms) pass only in that + workspace.** Produce the Rust side of a parity check at test time instead. +- **`TextEq` needs nothing from Postgres that does not already exist**, which + is part of why it could ship first. Equality lives entirely in `hm`, the + HMAC; the ciphertext `c` is sealed with a fresh IV, so two stored values + for the same plaintext are *different* JSON and an index on the column + itself never matches. The index EQL v3 is built for is a functional one on + the extracted term — + `create index … using hash (eql_v3_internal.eq_term(col))` (or `btree`: + the term's type rides on `bytea`'s default operator classes, so both work + and only `=` means anything) — and the bundle marks the extractor + `IMMUTABLE` and inlinable so the domain's `=` operator folds into the + query and the planner engages that index "structurally". The tracer + created **no** index on the encrypted column; its equality queries were + sequential scans. The ORE / OPE domains are the ones that need EQL's own + operator classes, because their terms do not sort as bytes. + +## Findings about Python and the toolchain + +- **pyo3 0.29, not 0.23**, for CPython 3.14. `abi3-py39` gives one wheel + per platform and builds against an interpreter newer than pyo3 knows. + Renames since the plan was written: `downcast` → `cast`, `allow_threads` + → `detach`, `PyObject` → `Py`. +- **`extension-module` must be maturin-only** (`[tool.maturin].features`), + not in `Cargo.toml`. On by default it stops `cargo test` and `cargo build` + linking (`Undefined symbols … _Py*`); maturin supplies + `-undefined dynamic_lookup`. `cargo check` is the compile check, + `maturin develop` the link check. +- **Anything that links pyo3 outside a wheel needs libpython on the loader + path** at run time (`DYLD_FALLBACK_LIBRARY_PATH` / `LD_LIBRARY_PATH` = + `sysconfig.get_config_var("LIBDIR")`), including `cargo test` and a + parity binary. CI must set it. +- **`Pending` is `IntoFuture`, not `Future`.** A sync shell is one Tokio + runtime, `into_future()` *before* `py.detach`, then `block_on`. There is + no second engine entry for sync, which keeps G6 reachable when async + comes. +- **Python's `int` has no width** and `34`/`34.0` derive different ORE + terms, so the annotation carries one (`Int64`, `Text`, …) and the shell + narrows exactly — stricter than `dynamic::read`, which converts lossless + widths and is right only for query literals. Check `bool` before `int`. + `None` encodes to `FfiValue::Null` and is refused by the declared kind. +- **The width markers should be a type, not a bare string**, or an unrelated + `Annotated[str, "a note"]` reads as a declaration. +- **psycopg plumbing** that touches no bytes: send a stored EQL value as + text with `::jsonb` in the SQL (`Jsonb(str)` wraps a JSON *string* and + fails the domain check); read it back as `email::text` and `.encode()` + (psycopg otherwise returns a `dict`). Postgres reorders keys; read by + name, never by position. +- **Environment quirks on this machine:** cargo and pip need the sandbox + off (shared `~/.cargo` writes; the proxy's TLS breaks pip and `gh`); + the repo's node scripts need node ≥ 20.11 (`import.meta.dirname`) — the + shell's is 20.3.1, mise has 24.11.1; `ghcr.io/cipherstash/postgres-eql` + needs a fresh `docker login ghcr.io`; the asdf `psql` shim has no + version, so install EQL through the container's own `psql`. + +## Design decisions made along the way (provisional — reviewers decide) + +- Targets resolve by **(kind, index)**, not by EQL name: Python writes + `{"kind": "string", "index": "eq"}` and the engine answers `TextEq` plus + both SQL domains. No EQL name is written in Python. An explicit + `EQL(name=...)` escape hatch exists. +- A **record is a dict of field name → column value** (EQL JSON as `bytes`, + passthrough as itself). It is what SQL wants, and no record ever needs a + serialised form. +- The **SQLAlchemy layer should be a separate PyPI distribution**, pure + Python, depending on the core wheel — the user's call on 2026-10-13; + not yet on the ticket. Backlog item 2 covers the call site, not the + shipping unit, so this is unowned. +- The live-test gate is "does the engine construct", not "are `CS_*` set". + +## Gaps against CIP-4340's wording, found on re-reading + +Two places where what was built is narrower than what the ticket says, and +the findings above would otherwise imply the ticket was met. + +- **"The engine checks the declaration when Python defines the class" + (week-1 step 2) — not quite.** The check runs at `build()`, one call + later, wherever the caller puts that call. + `Plan.of(User).context(…).build()` at module top level makes it import + time **by convention**; nothing fires when the `class` statement + finishes. A class decorator — `@stash.model("users")` above `@dataclass` + — would run `build()` at class definition **by construction**, hold the + `PlanSpec` on the class, and let the call site be `Cipher(User)`. It is a + second way in (G6), so it has to earn its place: it carries the context, + which is per-model and which `Annotated` cannot express, and it reaches + the moment the ticket names. The stronger form makes it *the* way and + retires `Plan.of` from the public surface. Costs: decorator order + (`@dataclass(slots=True)` returns a new class, so a plan set below it is + lost; a transforming base such as Pydantic's or SQLAlchemy's declarative + may rewrite the class after it was read), and committing to "the model + class owns its plan". A plain `@dataclass` below the decorator is + **fine** — a class's annotations exist before `@dataclass` runs, so an + earlier claim that the wrong order "sees no fields" was mistaken. Backlog + item 1. +- **The model contract is not "a dataclass", and should not become one.** + psycopg imposes nothing — it sees tuples and parameters. The shell relies + on exactly three things: annotated fields readable through + `get_type_hints(cls, include_extras=True)`; attribute access (`getattr`) + on the way in; and a **keyword-argument constructor** matching the field + names on the way out (`model(**row)` in `decrypt`). Dataclasses meet that + with the least ceremony, which is the only reason the tracer used them. + So do `attrs`, Pydantic, `NamedTuple`, and SQLAlchemy declarative models + (default constructor takes kwargs) — the first user's actual classes. + Restricting to `@dataclass` would exclude them while enforcing more than + the code needs. State the contract explicitly (a `Protocol`), and let the + SQLAlchemy layer supply a base that meets it. `is_dataclass` is the cheap + guard for decorator order, not the right one. + +## Defects found in the plan (`2026-10-08-python-sdk-tracer.md`) + +All ruled on and ledgered; listed so the restart's plan does not repeat them: +missing `dynamic`/`http` features; pyo3 0.23; `cargo build` as a check; +`"Utf8Str"`-style kind names; `FfiValue::String(Vec)` (it is +`Utf8String`); an invented `Value::kind_of`; a committed workspace-keyed +fixture; "Python encrypted" wording (Python never encrypts — the check is +the engine *through the shell* against the engine bare); the record as +`list[bytes]`; `decrypt_with`'s fifth argument (`expected: Option

+0900 Subject: [PATCH 065/109] refactor(python): the SQLAlchemy example uses configure_encryption The SQLAlchemy version of the customer directory called encrypt before each insert and decrypt after each select, and built the search term by hand. With configure_encryption, its endpoints use Session as any SQLAlchemy app does. It is the nearest copy of putting the layer into an existing app. The hooks check only the encrypted fields. cipher.encrypt also refused a created_at with no time zone, so the request model now uses Pydantic's AwareDatetime to keep that refusal.

Alembic would then create both. Now an index the model declares on the same term of the same column replaces the SDK's index for that term. A unique constraint on an encrypted column compares the stored EQL values. Each one has new random ciphertext, so the constraint never finds a duplicate. configure_encryption refuses it, and points to a unique index on eq_term instead. The example declares the unique index of schema.sql, and gives plan the text type, so Alembic finds no index or plan difference with the table.

Their `build` and `test` scripts never invoke cargo; `build:native`, `build:debug` and `test:cargo` do. - `languages/golang`: The Go module — the SDK `encrypt` with its generated-code support `encrypt/gensupport` and the policy packages `encrypt/policy` and `encrypt/policy/protosource`; the credential package `auth`; the generator `stashgen` and its command `cmd/stashgen`; and `internal` (the shared guest plumbing and the `record` wire model). A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused. Never tag a main commit by hand: `go get` would fetch a module with no guests. -- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin in `pyproject.toml`, never in a crate manifest, so `cargo test` links libpython. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so every crate it shares with the root workspace resolves to the version the root tests. After a root dependency moves, re-seed it the same way: copy the root `Cargo.lock` over it and run `cargo metadata --offline` there. That command prunes the copy to what the workspace uses. Until then, `tests-python.yml` fails on `--locked`. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version.

It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin in `pyproject.toml`, never in a crate manifest, so `cargo test` links libpython. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so every crate it shares with the root workspace resolves to the version the root tests. After a root dependency moves, re-seed it the same way: copy the root `Cargo.lock` over it and run `cargo metadata --offline` there. That command prunes the copy to what the workspace uses. Until then, `tests-python.yml` fails on `--locked`. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version.

A column type.** A SQLAlchemy `TypeDecorator` encrypts each value as SQLAlchemy writes it, and decrypts each value as it reads a row. This is the usual SQLAlchemy way to change a column's values. + +**B. Hooks that work on a whole statement or result (chosen).** + +- Writes: a `before_execute` hook on the engine. For each `INSERT` or `UPDATE` on a configured table, it encrypts the parameters of every row with one `Cipher.encrypt_rows` call. +- Reads: the `load` and `refresh` events of each class record the objects a query builds. A `do_orm_execute` hook then decrypts them, with one `Cipher.decrypt_rows` call for each class and set of fields. It sets the plaintext with `set_committed_value`, so the objects are not marked as changed. + +### Why B + +SQLAlchemy passes a column type one value at a time. So 100 rows would make 100 key requests. With B, they make one. The live test `test_100_objects_make_one_key_request_to_insert_and_one_to_load` in `tests/test_sqlalchemy_live.py` shows this. + +### What B needed + +- `Cipher.encrypt_rows` and `Cipher.decrypt_rows`. They take dicts that contain only some of the declared fields. An `UPDATE` has only the changed columns, plus keys such as the primary key for the `WHERE`. +- The engine refuses a row that leaves out a field of the plan. So these methods build a smaller plan for each set of fields. A value from the smaller plan opens and searches under the full plan. The live test `test_a_row_updated_with_some_fields_decrypts_and_searches_with_the_full_model` shows this. +- Every row in one call must contain the same declared fields. Then every value is checked before the one batch of key requests. SQLAlchemy sends one set of columns for each statement, so the hook meets this rule. + +## Decision 2: one setup call with an explicit list of classes + +`configure_encryption(engine, [Customer, Order])` takes the engine and the classes to encrypt. It does not find declared classes by itself, such as from the `Base` registry. An explicit list shows which tables are encrypted. A class imported late would otherwise be missed, with no error. + +It checks each class first, and raises `DeclarationError` before any query: + +| Code | The class has | +|---|---| +| `declaration_not_mapped` | no SQLAlchemy mapping | +| `declaration_table_mismatch` | a `__tablename__` that is not the table in `stackencrypt.model` | +| `declaration_column_name` | an encrypted field whose column has another name | +| `declaration_column_type` | an encrypted field whose column is not its marker's EQL type | +| `declaration_unique_column` | an encrypted field with a unique constraint | +| `declaration_already_configured` | a configuration from an earlier call | + +The hooks use field names, and SQLAlchemy uses column names in statement parameters. So a column with another name, such as `mapped_column("email_address")`, is refused for now. + +## Decision 3: refuse what would store or send plaintext + +The hooks can change only the parameters passed beside a statement. Three cases would put plaintext where the hooks cannot reach it. Each one raises an error before anything is sent. + +- **A value inside the SQL**, such as `insert(Customer).values(email=...)`. It raises `DeclarationError` with `declaration_inline_value`. +- **An operator that would send a value as plaintext**, such as `like`, `contains`, `between`, or `in_` with a subquery. It raises `QueryError` with `query_unsupported` when the app builds the query. The value could also never match an EQL value. +- **A unique constraint on an encrypted column.** Each EQL value contains new random ciphertext, so the constraint never finds a duplicate. A unique index on `eql_v4.eq_term(col)` works instead. + +The allowed operators are: + +- `==`, `<`, `<=`, `>`, and `>=`. Each one sends a query term made by the `Cipher` method of the same meaning. +- `!=`, as `NOT (col = term)`. +- `in_` and `not_in` with a list, as one equality term for each value, joined with `OR`. +- `is_(None)`, `is_not(None)`, `asc()`, and `desc()`. These send no value. + +The comparisons answer ADR-0002's open question. On the ORM, the field is named by the class attribute, such as `Customer.email`. The column type reads the attribute's name and calls the `Cipher` with it. + +## Decision 4: the column type comes from the marker + +`eql_type_map` is for SQLAlchemy's `type_annotation_map`. It maps each hint, such as `Annotated[str, TextEq]`, to an `EqlType` with that marker. The SQL type is the marker's `sql_domain`. So a model names no SQL type, and the type cannot disagree with the marker. + +The other option was an explicit type in each column, such as `mapped_column(Encrypted(TextEq))`. That repeats the marker in the hint. + +## Decision 5: the database indexes come from the markers + +Each marker lists its EQL indexes, such as `eq` for `TextEq`. When SQLAlchemy maps a class, the SDK adds one database index for each: + +| EQL index | Database index | +|---|---| +| `eq` | `hash (eql_v4.eq_term(col))` | +| `ope` | `btree (eql_v4.ord_term(col))` | +| `ore_block` | `btree (eql_v4.ord_term_ore(col))` | +| `match` | `gin (eql_v4.match_term(col))` | + +- The indexes are added when a class is mapped, not when a column joins a table. Alembic's `add_column` puts the new column on a temporary table, and creates that table's indexes. So an index added there was created twice. +- If the model declares its own index on the same term of the same column, the SDK adds none for that term. The customer directory example needs this. Its unique btree index on `eq_term(email)` also serves the search. + +The other option was to declare each index by hand. An index that is missing, or on the wrong function, makes a search slow with no error. + +## Decision 6: two Alembic hooks for env.py + +- `render_item` writes `stackencrypt.sqlalchemy.EqlType(stackencrypt.TextEq)` into a migration, with its imports. +- `process_revision_directives` changes two kinds of step: + - A change of an existing column to an EQL type becomes `op.execute` of an `ALTER` with `USING col::jsonb::`. PostgreSQL refuses the change without it, even with no rows. The cast changes an empty column, and refuses a column with plaintext rows. + - A type change between an EQL type and itself is dropped. Alembic compares types as text: `eql_v4_text_eq` from the database, and `public.eql_v4_text_eq` from the model. + +The other option was to leave the `USING` clause to the app, as a hand edit in each migration. + +## Decision 7: writes check passthrough values + +The write hook sends every declared field to `encrypt_rows`, not only the encrypted ones. So a passthrough value is checked as `encrypt` checks it, and stored unchanged. For example, a `datetime` with no time zone raises `value_naive_datetime`.

A session query of columns, such as select(Customer.email, Customer.plan), returned EQL values, though it is ordinary ORM code. The hook now finds the result columns that are encrypted fields, through attributes and labels, and decrypts them with one decrypt_rows call for each class and set of fields. A query on a connection is still left to the app, which calls cipher.decrypt_rows: a connection has no hook that can change a result.

ADR-0003 says the SQLAlchemy layer should hide this. .match(text) on a field with a match index is col @@ term, and the session hook runs verify on the rows after the query and removes those that fail. Removing rows after the query is right only in a session's select, with the match as a condition of the WHERE joined with AND, and whole objects of the class in the result. Anything else, such as or_, not_, a count, an update, or a query on a connection, raises QueryError before it is sent: it would return, count, or change rows that do not hold the text. A LIMIT is applied before the rows are removed, so a page can be short. ADR-0004 records the choice and the two other options.

With `cipher.encrypt` alone, `examples/customer-directory/app_sqlalchemy.py` could not use `Session` at all. + 2. **The same output, through the same code.** The hooks call `encrypt_rows` and `decrypt_rows`, which run the same `_engine.encrypt` and `_engine.decrypt`. Search terms come from the same `Cipher` methods. `test_a_row_updated_with_some_fields_decrypts_and_searches_with_the_full_model` shows that a value from a smaller plan opens and searches under the full plan. The example's `test_each_app_reads_what_the_other_wrote` shows the two ways read each other's rows. + 3. **The same guarantees, at the same stage.** The declaration is the same decorator. Every value, passthrough values included, is checked before any key request. Errors contain no value. A match search runs `verify` for the app. One difference: the read hook makes one `decrypt_rows` call for each class and set of fields, not one call for the whole result. If a later call fails, the query raises, and the app gets no result. + 4. **Someone owns it.** It has the README section "Use it with the SQLAlchemy ORM", ADR-0004, and four test files. `mise run test` and the `live` job of `tests-python.yml` run them. The owners of this repository, `@cipherstash/developers` in `.github/CODEOWNERS`, own it with the rest of the Python SDK. +- No test checks what SQLAlchemy logs with `echo=True`. The write hook runs before that log, so the log should show EQL values. ## G7.

A row with a missing value could not be stored. Most columns of an app being ported are nullable. Annotated[Optional[T], Marker] and T | None are now accepted. The plan gives the field "null": "sql", so the engine stores nothing for None and the column holds SQL NULL; decrypt reads it back as None. A query term for None is refused, and points to IS NULL. eql_type_map maps the Optional hints too, so SQLAlchemy makes the column nullable. "sql" shows which rows have no value. "sealed" would hide that, but only for fixed-width types with an equality index alone; it can come later. The ADR-0001 amendment records why.

The read hook refused every match inside an or_, so an app had to run one query for each field and join the rows in Python, which stops the database sorting and paging the combined result. A row that passes verify always passes @@, so the database returns every row that any branch would keep. The hook now accepts an or_ whose branches are all match searches, or and_ of them, and keeps a row when any branch passes verify. That gives exactly the rows verify would keep over the whole table. An or_ with any other condition, and a match under not_, are still refused.

A list relationship could not be marked Ignore, because SQLAlchemy reads the type directly inside Mapped, so an app removed the annotation and lost the type. Its hint also had to resolve when the decorator ran, so the target class had to come first. A relationship is never a column, so leaving it out cannot store plaintext. The decorator now finds the relationships in the class's SQLAlchemy mapper, which lists them when the class statement runs, and leaves them out of the plan without resolving their hints. Every column still needs a marker, as Rule A says.

An app that writes through more than one engine, such as an app engine, a test engine, and a worker run twice in one test, had no way to cover them, and a missed engine wrote without encryption. configure_encryption(classes) now installs the write hook once, on SQLAlchemy's Engine class, so every engine runs it, including one made later. A table is found by its Table object, not its name, so another database's table of the same name is not encrypted. A repeat call for a configured class does nothing; it still refuses a changed class, or a second class for the same table. The package is not released, so the signature change breaks no user.

A column collection accepts only a string key with `in`. So SQLAlchemy raised ArgumentError for a class with an encrypted field and any UniqueConstraint on its table. That includes the one that unique=True makes for a plaintext column. The check now uses contains_column. An encrypted column in a composite UniqueConstraint is now refused with declaration_unique_column, the same as a column declared unique=True. A unique plaintext column beside an encrypted one is accepted.

Two causes, both in the tests. The offline jobs have no CipherStash profile. The module-scoped scores fixture called configure_encryption before the function-scoped credentials fixture set the fake credentials, and one declaration case built a Cipher with no credentials fixture. Both now ask for credentials. They passed locally only because of a ~/.cipherstash profile. The live job sets EQL_TEST_DATABASE_URL as a libpq keyword string. psycopg reads it, but SQLAlchemy's create_engine reads only a URL. A new helper, sqlalchemy_url, turns either form into a SQLAlchemy URL for psycopg 3. Both live SQLAlchemy test files use it.

They get no Actions secrets, so require-cs-secrets failed on every one. - An example-only change no longer starts the workflow. CI does not run the example's tests. - .cargo/** and EQL's Cargo.toml and Cargo.lock now start it. Cargo reads the first for this workspace. The EQL build uses the other two. - A pull request's wheel records the PR's head commit. GitHub's test merge commit is on no branch, so a bug report could not name it. - maturin is fixed at v1.16.0, inside pyproject.toml's range. - wheels-summary runs when a leg fails, so the passing legs still get their build-time row. Addresses review threads 1513-F5, 1499-F2, 1499-F12, 1621-F5, and 1406-F1, F2, F3, F5.

Now the decorator replaces only a method that dataclasses, attrs, or NamedTuple generated. It refuses anything else on the class with declaration_repr_present. The field reader had five faults: - It refused a correctly placed marker around a generic value type, such as re.Pattern[str]. - It read dunder annotations, such as __tablename__, as fields. - An AttributeError or a SyntaxError from a hint escaped with no field name. - Before Python 3.14, it named the wrong field after a string ClassVar hint. - It did not refuse a required Ignore field with a Pydantic alias or an attrs private name. The fixes: - Only a SQLAlchemy wrapper is refused inside the marker's Annotated. - Dunder names are skipped. - The four hint errors give declaration_hints_unresolved. - Each hint is resolved on a probe class, not a probe function. - An Ignore field is looked up by its constructor name. - A Pydantic dataclass's config is read from __pydantic_config__.

It now refuses a model that is not an instance of the declared class, with value_wrong_type. A datetime whose tzinfo gives no UTC offset is naive in Python. The value reader now checks utcoffset(), so such a value gives value_naive_datetime, not a TypeError. decrypt turned every error from json.dumps into decrypt_malformed. That included KeyboardInterrupt and MemoryError. Now only TypeError, ValueError, and RecursionError do so. An error raised while a passthrough value is read now propagates, as it does on encrypt. One row passed on its own, for example from fetchone(), was read as a list of column names. decrypt, decrypt_rows, and encrypt_rows now refuse it and say to pass [row]. A str with a lone surrogate now gives decrypt_malformed, the same as bytes that are not UTF-8. encrypt now has the type Sequence[T]. Addresses review threads 1499-F5, 1499-F6, and 1509-F4, F5, F6, F8, F9.

A frame writer writes a typed null as the plain null, so the test expects no type there. - The SIGINT gate tests cancel and join their timer in finally. - A class read from its hints leaves out ClassVar and InitVar, and rule A holds inside Mapped on a real mapped class. - repr of an expired or detached SQLAlchemy row sends no SQL statement. - After the switch to the deterministic client, the live client and a second switch are refused. test:cargo runs this test binary with the deterministic-kms feature. A seed that is not 32 bytes is refused. - decrypt runs from 8 threads at once, live and deterministic. - The keyset test fails if the load-keyset counter is missing.

Together they close the review threads tagged as quick wins. Build and engine: - build.rs fails when git status fails. Before, it recorded a clean commit. -dirty now also covers the root Cargo.toml and the Python Cargo.lock, which choose the engine's dependency versions. - run! gives its value in both builds. Before, the test build returned from the calling function. - The allocator spy uses a poisoned lock as it is. A panic inside the allocator would abort the test binary with no message. Tests: - The value tests refuse both sides of each integer range, a float too large for float32, and a decimal mantissa one past 96 bits. The edge-value test builds the cipher outside pytest.raises. - Refusals of a hand-written or replaced __str__ and __rich_repr__, and of a changed or removed hint. - A constructor's own error reaches the caller of decrypt unchanged. A dict with no JSON form gives decrypt_malformed. - The thread helpers time out and name the failed thread. Other helpers give clearer failure messages, and the Go-row tests check lengths before zip. - The conformance test compares vector names, not counts. - The CI script tests check that their scans find something, test the triggers() helper, and hold the deterministic build's features to pyproject.toml's. - The codegen test shows that a refused override writes no file. - The ClassVar test from the last commit keeps its bare ClassVar case for Python 3.10 and later. Python 3.9 cannot resolve one written as a string. Docs and example: - AGENTS.md says which job builds the wheels, where extension-module is named, and what test:cargo runs. - G6 on the scorecard is strained: it lists two gaps with no test. - The example builds EQL before it deletes its database volume, says to trust EQL's mise file, and accepts a postgres:// URL.

They are the members of the **root Cargo workspace**, with the three node binding crates below. See "Working on the Rust crates". - `languages/typescript/packages/auth`, `languages/typescript/packages/profile`, `languages/typescript/packages/stack-auth-wasm`: The node bindings of those crates. `@cipherstash/auth` (napi-rs v2) and its six `platforms/*` packages are published to npm from this repository by `release.yml` (`auth-artifacts`, `publish-auth`); a change to what it ships, the `stack-auth` crate included, needs an `@cipherstash/auth` changeset (`require-auth-npm-changeset.yml`). `@cipherstash/profile` and its platforms are private and never published; `@cipherstash/stack-auth-wasm` is private and builds the wasm that `@cipherstash/auth` ships. Their `build` and `test` scripts never invoke cargo; `build:native`, `build:debug` and `test:cargo` do. - `languages/golang`: The Go module — the SDK `encrypt` with its generated-code support `encrypt/gensupport` and the policy packages `encrypt/policy` and `encrypt/policy/protosource`; the credential package `auth`; the generator `stashgen` and its command `cmd/stashgen`; and `internal` (the shared guest plumbing and the `record` wire model). A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused. Never tag a main commit by hand: `go get` would fetch a module with no guests. -- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin in `pyproject.toml`, never in a crate manifest, so `cargo test` links libpython. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so every crate it shares with the root workspace resolves to the version the root tests. After a root dependency moves, re-seed it the same way: copy the root `Cargo.lock` over it and run `cargo metadata --offline` there. That command prunes the copy to what the workspace uses. Until then, `tests-python.yml` fails on `--locked`. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs `mise run test:live`: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It skips on a fork's pull request, and the task fails on any skipped test. It then builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic. The package has no runtime dependency, so nothing else is locked. attrs, Pydantic, and SQLAlchemy are for the declaration tests, and SQLAlchemy also for `stackencrypt.sqlalchemy`. psycopg is for the live tests. Alembic is for the tests of the migrations that `stackencrypt.sqlalchemy`'s two Alembic hooks write. `mise run build` installs them with `uv sync --locked`, so a lock that does not match `pyproject.toml` fails the build. After a change to the `test` extra, run `uv lock` in `languages/python`. None has an upper bound. Dependabot's `uv` entry proposes each new minor or patch release as a lock update. maturin, the build backend, is not locked. `python/stackencrypt/_eql.py`, the EQL type markers, is generated from the EQL catalog by `eql-codegen py-eql`. To regenerate it, run `mise run types:generate` in `packages/eql`. Never edit it by hand: `tests-python.yml` runs its parity tests and fails on a hand edit. Design: the Python ADRs under `languages/python/docs/adr/` (ADR-0001, the declaration; ADR-0002, a query names its field by a string; ADR-0003, one method for each query operator; ADR-0004, the SQLAlchemy layer encrypts in batch hooks), the spec in #1341. `languages/python/docs/scorecard.md` marks the eight shared principles of `docs/sdk-design-principles.md` against the code. The README's SQL and Python blocks run in order in the `live` job, through `tests/test_readme_live.py`, so a change to a README step needs that test to pass. +- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one.

The decorator reported it as an unresolved name, and told the user to define or import it. Nothing was missing, so that advice did not help. The decorator now evaluates the hint that failed. If it is ClassVar with no type, the error says to write ClassVar[int], with the reason bare_class_var. The evaluation is Python's own, so typing.ClassVar and an alias are found too.

Its next call never returned. The client is now stored with the ID of the process that built it. A child builds its own client on its first call, and loads the keyset again. The parent's copy is never dropped in the child: dropping a runtime whose threads are gone could block. macOS does not allow its TLS certificate service in a child that fork made, so on macOS the child crashes when it builds its client. The test skips on macOS, and test:live leaves it out there. CI runs it on Linux. run! also had a label that only the test build used. clippy with -D warnings refused it in the normal build. It is allowed now. Addresses review thread 1499-F4.

Its next call never returned. Building a new runtime in the child is not safe either. tokio's locks keep a process-wide table of waiting threads, and the child's copy lists the parent's threads. On Linux, a new runtime in the child blocked in 8 of 15 runs. So a child that fork made after the client was built is now refused, with StashError code stack_forked. The message says to make the first call after the fork. The check reads a OnceLock and an atomic process ID, and takes no lock, so it cannot block. A child forked before any call builds its own client, as before. The fork test covers both cases, and runs on macOS and Linux. On Linux, each case passed 15 of 15 runs.

That was no longer true: the Python lock had vitaminc 0.8.1, and the root lock had 0.8.0. No check compared the two locks. The Python lock is seeded from the root lock again. The difference was small: 0.8.1 adds a storage profile to vitaminc-aead-frame. The SDK does not use it. The encryption and order crates have the same source in both versions. The documented steps were not enough to re-seed: cargo metadata moved vitaminc back to 0.8.1, and cargo update --precise moved each crate to 0.8.0. AGENTS.md now gives that step. python-lock-parity.test.mjs compares the crates that decide what a stored value is, by version, source and checksum: every vitaminc crate, recipher, ore-rs, clww-ore, cts-common and zerokms-protocol. Other shared crates may differ. The lock parser moves to lib/cargo-lock.mjs, so this test and the cipherstash-client one share it. The deterministic suite still opens the Go SDK's frozen rows and seals the same values, so vitaminc 0.8.0 gives the same results here. Addresses review thread 1406-F4.

Their `build` and `test` scripts never invoke cargo; `build:native`, `build:debug` and `test:cargo` do. - `languages/golang`: The Go module — the SDK `encrypt` with its generated-code support `encrypt/gensupport` and the policy packages `encrypt/policy` and `encrypt/policy/protosource`; the credential package `auth`; the generator `stashgen` and its command `cmd/stashgen`; and `internal` (the shared guest plumbing and the `record` wire model). A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused. Never tag a main commit by hand: `go get` would fetch a module with no guests. -- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin, never in a crate manifest, so `cargo test` links libpython. `pyproject.toml` sets it, and `test:deterministic` names it again in its `--features` list; `scripts/__tests__/python-ci.test.mjs` holds the two lists together. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. It also runs one test binary of `crates/core`, `deterministic_switch`, with the `deterministic-kms` feature: the switch is for the whole process, so that test needs a process of its own. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so every crate it shares with the root workspace resolves to the version the root tests. After a root dependency moves, re-seed it the same way: copy the root `Cargo.lock` over it and run `cargo metadata --offline` there. That command prunes the copy to what the workspace uses. Until then, `tests-python.yml` fails on `--locked`. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs `mise run test:live`: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic. The package has no runtime dependency, so nothing else is locked. attrs, Pydantic, and SQLAlchemy are for the declaration tests, and SQLAlchemy also for `stackencrypt.sqlalchemy`. psycopg is for the live tests. Alembic is for the tests of the migrations that `stackencrypt.sqlalchemy`'s two Alembic hooks write. `mise run build` installs them with `uv sync --locked`, so a lock that does not match `pyproject.toml` fails the build. After a change to the `test` extra, run `uv lock` in `languages/python`. None has an upper bound. Dependabot's `uv` entry proposes each new minor or patch release as a lock update. maturin, the build backend, is not locked. `python/stackencrypt/_eql.py`, the EQL type markers, is generated from the EQL catalog by `eql-codegen py-eql`. To regenerate it, run `mise run types:generate` in `packages/eql`. Never edit it by hand: `tests-python.yml` runs its parity tests and fails on a hand edit. Design: the Python ADRs under `languages/python/docs/adr/` (ADR-0001, the declaration; ADR-0002, a query names its field by a string; ADR-0003, one method for each query operator; ADR-0004, the SQLAlchemy layer encrypts in batch hooks), the spec in #1341. `languages/python/docs/scorecard.md` marks the eight shared principles of `docs/sdk-design-principles.md` against the code. The README's SQL and Python blocks run in order in the `live` job, through `tests/test_readme_live.py`, so a change to a README step needs that test to pass. +- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin, never in a crate manifest, so `cargo test` links libpython. `pyproject.toml` sets it, and `test:deterministic` names it again in its `--features` list; `scripts/__tests__/python-ci.test.mjs` holds the two lists together. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. It also runs one test binary of `crates/core`, `deterministic_switch`, with the `deterministic-kms` feature: the switch is for the whole process, so that test needs a process of its own. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so the crates that decide what a stored value is resolve to the versions the root tests: every `vitaminc` crate, `recipher`, `ore-rs`, `clww-ore`, `cts-common` and `zerokms-protocol`. `scripts/__tests__/python-lock-parity.test.mjs` compares those crates in the two locks, by version, source and checksum. Other shared crates may differ. To re-seed, copy the root `Cargo.lock` over it and run `cargo metadata` there. That command prunes the copy to what the workspace uses. It can also move a crate to a newer version, when this workspace turns on a feature the root does not. Move each such crate back with `cargo update -p @ --precise `, until the parity test passes. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs `mise run test:live`: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic.

It has its own `pyproject.toml` and `uv.lock`, and installs `stackencrypt` from this checkout.

So every step could read them, the builds included. A build runs third-party code: each dependency's build.rs and proc-macros, and maturin. The credentials now go to the Live tests step only. A step before it builds the extension and the EQL bundle, with no credentials. The live tests run through test:live:run, a new task that builds nothing. build:eql-bundle is the other new task. test:live still builds and runs everything, for local use. python-ci.test.mjs requires CI to run every Python task. test:live is exempt, with its reason, because CI runs it in parts. maturin is still installed unlocked (review thread 1582-F1). It now runs without the credentials. Addresses review thread 1499-F1, and in part 1582-F1.

Their `build` and `test` scripts never invoke cargo; `build:native`, `build:debug` and `test:cargo` do. - `languages/golang`: The Go module — the SDK `encrypt` with its generated-code support `encrypt/gensupport` and the policy packages `encrypt/policy` and `encrypt/policy/protosource`; the credential package `auth`; the generator `stashgen` and its command `cmd/stashgen`; and `internal` (the shared guest plumbing and the `record` wire model). A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused. Never tag a main commit by hand: `go get` would fetch a module with no guests. -- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin, never in a crate manifest, so `cargo test` links libpython. `pyproject.toml` sets it, and `test:deterministic` names it again in its `--features` list; `scripts/__tests__/python-ci.test.mjs` holds the two lists together. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. It also runs one test binary of `crates/core`, `deterministic_switch`, with the `deterministic-kms` feature: the switch is for the whole process, so that test needs a process of its own. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so the crates that decide what a stored value is resolve to the versions the root tests: every `vitaminc` crate, `recipher`, `ore-rs`, `clww-ore`, `cts-common` and `zerokms-protocol`. `scripts/__tests__/python-lock-parity.test.mjs` compares those crates in the two locks, by version, source and checksum. Other shared crates may differ. To re-seed, copy the root `Cargo.lock` over it and run `cargo metadata` there. That command prunes the copy to what the workspace uses. It can also move a crate to a newer version, when this workspace turns on a feature the root does not. Move each such crate back with `cargo update -p @ --precise `, until the parity test passes. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs `mise run test:live`: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic. The package has no runtime dependency, so nothing else is locked. attrs, Pydantic, and SQLAlchemy are for the declaration tests, and SQLAlchemy also for `stackencrypt.sqlalchemy`. psycopg is for the live tests. Alembic is for the tests of the migrations that `stackencrypt.sqlalchemy`'s two Alembic hooks write. `mise run build` installs them with `uv sync --locked`, so a lock that does not match `pyproject.toml` fails the build. After a change to the `test` extra, run `uv lock` in `languages/python`. None has an upper bound. Dependabot's `uv` entry proposes each new minor or patch release as a lock update. maturin, the build backend, is not locked. `python/stackencrypt/_eql.py`, the EQL type markers, is generated from the EQL catalog by `eql-codegen py-eql`. To regenerate it, run `mise run types:generate` in `packages/eql`. Never edit it by hand: `tests-python.yml` runs its parity tests and fails on a hand edit. Design: the Python ADRs under `languages/python/docs/adr/` (ADR-0001, the declaration; ADR-0002, a query names its field by a string; ADR-0003, one method for each query operator; ADR-0004, the SQLAlchemy layer encrypts in batch hooks), the spec in #1341. `languages/python/docs/scorecard.md` marks the eight shared principles of `docs/sdk-design-principles.md` against the code. The README's SQL and Python blocks run in order in the `live` job, through `tests/test_readme_live.py`, so a change to a README step needs that test to pass. +- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one.

So six seeds decoded as Write, and the seventh as a Read of one byte. No seed reached the read check, and CI's replay never ran it. Putting the Read tag in front of each seed is not enough. arbitrary 1.5.0 puts a byte of its own before each Vec element, so an arbitrary input never contains a frame byte for byte. The target now takes raw bytes, and the first byte chooses the branch. 0x00 is Read, and the rest of the input is the frame, byte for byte. Any other byte is Write, decoded through arbitrary as before. Each seed now starts with 0x00. On current nightly, all seven seeds reach the read check, and the replay passes.

Each now has a status line. + +### 1. The README does not warn about Pydantic's `ValidationError` + +`Customer` is a Pydantic model that contains plaintext. By default, Pydantic prints the rejected input in a `ValidationError`. FastAPI's default 422 response also repeats the input: the example's first run returned `"input":"bad"`. + +The README's list of what still shows plaintext names `model_dump`, `vars`, `pickle`, and others. It does not name either of these. + +The example sets `hide_input_in_errors=True` and replaces FastAPI's 422 response. `tests/test_app.py` covers both. + +Suggested action: add both to the README's list, with the setting that hides the input. + +### 2. The README has no recipe for a database-generated key + +The README covers a UUID key only. A required integer `id` on the model cannot work, because the model is encrypted before PostgreSQL creates the `id`. + +The example leaves `id` out of the model. It works, but the model then cannot return the `id`. + +Suggested action: add the database-generated case to "Store a UUID key". + +### 3. `decrypt` does not say whether it keeps row order + +Neither the `decrypt` docstring nor the README says that results come back in the order of the input rows. An application that needs a column outside the model must pair it with the decrypted result by position. + +The example avoids this by not returning `id`. I did not test the order. + +Suggested action: state the guarantee, and add a test for it. + +### 4. The README does not cover uniqueness on an encrypted column + +The README shows only a hash index, and PostgreSQL cannot make a hash index unique. This B-tree index works: + +```sql +CREATE UNIQUE INDEX customers_email_unique ON customers (eql_v4.eq_term(email)); +``` + +A second insert with the same email raises `UniqueViolation` with SQLSTATE 23505. `EXPLAIN` shows an index scan on this index for `WHERE email = %s::eql_v4.query_text_eq`, with `enable_seqscan` off. + +Suggested action: document the unique index, and say that equal emails produce equal terms. + +### 5. The README has no write or read path for SQLAlchemy + +The README shows how to declare a SQLAlchemy model, including relationships. It does not show an insert or a query. `app_sqlalchemy.py` needed three things that the README does not mention: + +- A custom column type. The tests fail with `sa.Text`, `sa.String`, or `sa.JSON` in its place. +- `sa.insert(Customer.__table__)` with the rows from `encrypt`, in place of `Session.add`. +- A `sa.cast` of the query term to `eql_v4.query_text_eq`. + +The `id` column works when it is marked `Ignore`. Search with these statements uses the unique index, as `EXPLAIN` shows with `enable_seqscan` off. + +Python ADR-0002 mentions a later SQLAlchemy layer. Until it exists, this is hand-written code for each application. + +Suggested action: add this recipe to the README, or say that the layer is planned. + +Status: addressed by the SQLAlchemy layer, `stackencrypt.sqlalchemy`. `app_sqlalchemy.py` now calls `configure_encryption([Customer])`. Its endpoints use `session.add` and `session.scalars`, with no SDK calls. The README section "Use it with the SQLAlchemy ORM" shows the write and the read. + +### 6. `Session.add` sends plaintext to PostgreSQL before it fails + +`Session.add` with a normal `Customer` object fails with a `DataError`, and no row is stored. But the plaintext has already reached the PostgreSQL server. The error text quotes the start of the value, even with `hide_parameters=True`: + +```text +DETAIL: Token "zed" is invalid. +CONTEXT: JSON data, line 1: zed... +``` + +The example logs only PostgreSQL's primary message, so this text is not in its log. An application that logs the exception would write part of the plaintext. A PostgreSQL server that logs errors could also record it. I did not check the server's log. + +Suggested action: warn about this in the README. The later SQLAlchemy layer could refuse this case before anything is sent. + +Status: addressed by the SQLAlchemy layer. Its write hook encrypts the values before SQLAlchemy sends the statement, so `Session.add` sends no plaintext. I did not check this example's PostgreSQL log again. + +### 7. A decrypted SQLAlchemy object is not connected to a session + +`select(Customer)` returns ciphertext dicts in `.email` and `.name`. `decrypt` returns new objects that SQLAlchemy reports as transient, with `id` set to `None`. So the usual pattern of loading an object, changing it, and committing it does not work. + +Suggested action: state this limit in the README. + +Status: addressed by the SQLAlchemy layer. A session query builds its objects as usual. The read hook then decrypts them in place with `set_committed_value`, so they are not marked as changed (ADR-0004). `tests/test_sqlalchemy_live.py` checks `session.dirty` after a load. + +### 8. Two `decrypt` errors from the engine do not name the row + +Most `decrypt` errors name the row and the field, such as `row 317, field "email"`. Two codes name the field only, when the engine finds the problem: + +- `decrypt_malformed`, for a value with an `i` that is not the field's EQL type. The engine refuses it before any key request. +- `decrypt_kind_mismatch`, for a value sealed as another type. The engine finds it after the value opens, so after the key requests. + +In a batch of 500 rows, the user must then search every row for the bad value. The Go SDK has the same gap: `Client.open` in `languages/golang/encrypt/records.go` returns the engine's error unchanged. Review thread 1509-F7 reported it for Python. + +The SDK could find the row for `decrypt_malformed` by running the engine's check again one row at a time. That needs a copy of every row's ciphertext on every call, and it cannot help with `decrypt_kind_mismatch` without new key requests. It would also make Python differ from Go. + +Suggested action: have the engine name the row in both refusals, so that Python and Go both get it.

It copied two private pieces of that builder: the reader of CS_ZEROKMS_HOST in stack-kms, and the client key provider in stack-encrypt. A change to either would not reach Python, and no test would report it. stack-kms now exports endpoint_from_env, the reader the builder uses. stack-encrypt now exports client_key_provider, the provider init uses: the environment first, then the stash profile. The Python client calls both, and its copies are gone. The two copies had already drifted: with no client key and no profile, Python now gives the engine's message, which says npx stash auth login. The wasm32 variant of client_key_provider named KeyProvider, which is imported only for other targets. It now uses the full path. Nothing in CI builds stack-encrypt's http feature for wasm32.

They are the members of the **root Cargo workspace**, with the three node binding crates below. See "Working on the Rust crates". - `languages/typescript/packages/auth`, `languages/typescript/packages/profile`, `languages/typescript/packages/stack-auth-wasm`: The node bindings of those crates. `@cipherstash/auth` (napi-rs v2) and its six `platforms/*` packages are published to npm from this repository by `release.yml` (`auth-artifacts`, `publish-auth`); a change to what it ships, the `stack-auth` crate included, needs an `@cipherstash/auth` changeset (`require-auth-npm-changeset.yml`). `@cipherstash/profile` and its platforms are private and never published; `@cipherstash/stack-auth-wasm` is private and builds the wasm that `@cipherstash/auth` ships. Their `build` and `test` scripts never invoke cargo; `build:native`, `build:debug` and `test:cargo` do. - `languages/golang`: The Go module — the SDK `encrypt` with its generated-code support `encrypt/gensupport` and the policy packages `encrypt/policy` and `encrypt/policy/protosource`; the credential package `auth`; the generator `stashgen` and its command `cmd/stashgen`; and `internal` (the shared guest plumbing and the `record` wire model). A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused. Never tag a main commit by hand: `go get` would fetch a module with no guests. -- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion. The root `mise.toml`'s `fuzz:python-values` task runs it, from `fuzz.yml`, so it is the one Python task outside `languages/python/mise.toml`. `crates/core/testdata/value-conformance.json` is a copy of vitaminc's shared value corpus; its `README.md` records the commit it came from. `crates/core` compiles the Go guest's EQL resolver, `languages/golang/encrypt/guest/src/targets.rs`, in place through `#[path]`. So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin, never in a crate manifest, so `cargo test` links libpython. `pyproject.toml` sets it, and `test:deterministic` names it again in its `--features` list; `scripts/__tests__/python-ci.test.mjs` holds the two lists together. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. It also runs one test binary of `crates/core`, `deterministic_switch`, with the `deterministic-kms` feature: the switch is for the whole process, so that test needs a process of its own. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so the crates that decide what a stored value is resolve to the versions the root tests: every `vitaminc` crate, `recipher`, `ore-rs`, `clww-ore`, `cts-common` and `zerokms-protocol`. `scripts/__tests__/python-lock-parity.test.mjs` compares those crates in the two locks, by version, source and checksum. Other shared crates may differ. To re-seed, copy the root `Cargo.lock` over it and run `cargo metadata` there. That command prunes the copy to what the workspace uses. It can also move a crate to a newer version, when this workspace turns on a feature the root does not. Move each such crate back with `cargo update -p @ --precise `, until the parity test passes. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs the live tests: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It builds the extension and the bundle in a step with no credentials, then runs `mise run test:live:run`, which builds nothing, in the only step that has them. So no dependency's build script runs with the credentials set. Locally, `mise run test:live` does both. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic. The package has no runtime dependency, so nothing else is locked. attrs, Pydantic, and SQLAlchemy are for the declaration tests, and SQLAlchemy also for `stackencrypt.sqlalchemy`. psycopg is for the live tests. Alembic is for the tests of the migrations that `stackencrypt.sqlalchemy`'s two Alembic hooks write. `mise run build` installs them with `uv sync --locked`, so a lock that does not match `pyproject.toml` fails the build. After a change to the `test` extra, run `uv lock` in `languages/python`. None has an upper bound. Dependabot's `uv` entry proposes each new minor or patch release as a lock update. maturin, the build backend, is not locked. `python/stackencrypt/_eql.py`, the EQL type markers, is generated from the EQL catalog by `eql-codegen py-eql`. To regenerate it, run `mise run types:generate` in `packages/eql`. Never edit it by hand: `tests-python.yml` runs its parity tests and fails on a hand edit.

The README's SQL and Python blocks run in order in the `live` job, through `tests/test_readme_live.py`, so a change to a README step needs that test to pass. +- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one.

The build now records which process holds the lock, and a child that finds its parent's build in progress refuses with stack_forked. A fork between taking the lock and storing the client is still not caught; the comment in client.rs says so. encrypt took one model on its own and split a Pydantic model or a NamedTuple into its fields. decrypt took a SQLAlchemy Row or one EQL value as a row. All three now give a refusal that names the fix. attrs generates __str__ in its own module, so redaction did not recognise it and the model's str() printed plaintext. Redaction now accepts code from attr._make named __str__. The rest are smaller: the declaration reads each base class's namespaces once, the wheels job checks out the commit under test, the CI test holds maturin's version to uv.lock and reads --features from the test:deterministic task itself, and the live job's comments say the build and test steps still share a runner.

A wazero host with no cgo. Its two WASI guests (`encrypt/guest`, `auth/guest`) are detached Cargo workspaces built by `mise run wasm:guest:build` and `mise run wasm:auth-guest:build`; `mise run wasm:guest:build:deterministic` builds the seeded TEST build the hermetic Go tests use; the `.wasm` files they embed are gitignored. The stack-encrypt guest has a second build with the EQL types (`mise run wasm:guest:build:eql`, cargo feature `eql`, linking `eql-bindings` by path; `wasm:guest:build:eql:deterministic` is its test build), embedded by `encrypt/eql` and registered on import, so a program whose generated code names an EQL type runs it (ADR-0007, amended). `encrypt/eql`'s types and `Types` table are generated from the EQL catalog by `eql-codegen` (`eql_gen.go`, written by `mise run types:generate` in `packages/eql` and drift-gated by `types:check` and `cargo test -p eql-codegen`). Generated `*_stash.go` files are committed and CI fails when `go generate ./...` changes one. Releases are cut by hand with `.github/workflows/release-golang.yml` (`gh workflow run release-golang.yml -f version=X.Y.Z[-pre] --ref `): because the guests are gitignored on main and Go fetches a version as the files committed at its tag, the workflow builds them, commits them on a release-only commit no branch points at, tags it `languages/golang/vX.Y.Z` and pushes the tag alone, then attaches the EQL v4 SQL bundle to the GitHub release. The ref must carry the EQL v4 bundle, or the build stops at "Build the EQL SQL bundles". `scripts/go-release-version.mjs` refuses, before anything is built, every version Go would refuse (non-canonical semver, `+build` metadata, a v2+ major on a module path with no `/vN` suffix, a version shaped like a pseudo-version), a final version dispatched from anywhere but `main`, and a final version while `languages/golang/go.mod` pins a `github.com/cipherstash/vitaminc/…` module at a pseudo-version (vitaminc's Go bindings have no tags, and a TEMPORARY pin on an unreleased commit must be gone before the module is tagged); a pre-release may come from a branch and may carry such a pin. The build job also refuses a version the Go proxy already lists in `@v/list`, which catches a tag deleted after the proxy fetched it; it never asks the proxy for the version itself before the tag exists, because the proxy would cache "not found" for up to 30 minutes and `verify` would fail after the push. The build checks the `Cargo.lock` of the EQL workspace and both guest workspaces with `--locked` first, since none of those builds passes it. It runs in a job with no write token and hands the guests to a `publish` job that holds `contents: write` and runs only git and gh. `publish` fetches the commit with plain unauthenticated git rather than `actions/checkout`, whose `token` input defaults to the job's writable token, and refuses a release commit whose tree is not the one the build tested. `publish` takes the paths it commits from the workflow's fixed `GUESTS` list, never from the artifact, and refuses a `guests.sha256` that is not exactly one SHA-256 line for each of those three guests: the build job runs third-party code after writing that manifest, so a path read from it could put any file on the tag (`scripts/__tests__/go-release-artifact.test.mjs`). A version is immutable once the Go proxy has fetched it, so a tag is never moved or deleted: if `publish` or `verify` fails after the tag is pushed, use "Re-run failed jobs" on the same run, which keeps a tag that run pushed and creates or completes the release; a new dispatch of the same version is refused.

So both SDKs run one resolver, and a change to that file is a change to both. The `extension-module` feature is set only by maturin, never in a crate manifest, so `cargo test` links libpython. `pyproject.toml` sets it, and `test:deterministic` names it again in its `--features` list; `scripts/__tests__/python-ci.test.mjs` holds the two lists together. Its tasks live in its own `mise.toml` and run from that folder. `mise run build` builds the wheel into `.venv`. `mise run test` runs pytest. `mise run test:cargo` runs plain `cargo test --locked` for both crates, with libpython on the loader path. It also runs one test binary of `crates/core`, `deterministic_switch`, with the `deterministic-kms` feature: the switch is for the whole process, so that test needs a process of its own. Its extension tests include `crates/engine/src/heap_hygiene.rs`: a spy allocator fails the test when a block the extension frees during `encrypt`, `query` or `decrypt` still contains text or decimal plaintext. Python's own objects are out of its scope. It runs on Unix, and CI runs it on Linux. `mise run test:deterministic` rebuilds the extension with the `deterministic-kms` test feature, whose keys come from a seed through stack-kms's `DeterministicSource`. It then runs `tests_deterministic/` in its own pytest process: Python opens the EQL rows the Go SDK stored under that seed in `packages/eql/tests/encryption/fixtures/`, the frozen `stored_v4_rows_v1.json` among them, and seals the same values to the same terms. It does not use nextest, and its CI job sets no `MISE_ENV`. The nextest rule under "Working on the Rust crates" is for the root workspace, whose `stack-kms` tests set environment variables. No test in this workspace does, and nextest comes from `mise.test.toml`, which this workspace's CI does not load. The wheel's version is `crates/engine/Cargo.toml`'s. `stackencrypt.__engine__` is the commit of this checkout, recorded by `crates/core/build.rs`. Its `Cargo.lock` is seeded from the root one, so the crates that decide what a stored value is resolve to the versions the root tests: every `vitaminc` crate, `recipher`, `ore-rs`, `clww-ore`, `cts-common` and `zerokms-protocol`. `scripts/__tests__/python-lock-parity.test.mjs` compares those crates in the two locks, by version, source and checksum. Other shared crates may differ. To re-seed, copy the root `Cargo.lock` over it and run `cargo metadata` there. That command prunes the copy to what the workspace uses. It can also move a crate to a newer version, when this workspace turns on a feature the root does not. Move each such crate back with `cargo update -p @ --precise `, until the parity test passes. Nothing is published. CI is `tests-python.yml`. It runs the Rust checks and pytest on Python 3.9 and 3.14, where `MISE_PYTHON_VERSION` moves a leg off the local version. A `live` job runs the live tests: `encrypt`, `decrypt` and the query methods against ZeroKMS with the repository's `CS_*` secrets, and the rows inserted into, searched in and read back from a `postgres:17` service with the EQL v4 bundle built from the tree. It builds the extension and the bundle in a step with no credentials, then runs `mise run test:live:run`, which builds nothing, in the only step that has them. So no dependency's build script runs with the credentials set. Locally, `mise run test:live` does both. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic. It also locks maturin, the build backend, in the `build` dependency group. The package has no runtime dependency, so nothing else is locked. attrs, Pydantic, and SQLAlchemy are for the declaration tests, and SQLAlchemy also for `stackencrypt.sqlalchemy`. psycopg is for the live tests. Alembic is for the tests of the migrations that `stackencrypt.sqlalchemy`'s two Alembic hooks write. `mise run build` installs them with `uv sync --locked`, so a lock that does not match `pyproject.toml` fails the build. It then builds the package with `--no-build-isolation`, through the locked maturin in `.venv`, so uv downloads no build tool outside the lock. After a change to the `test` extra, run `uv lock` in `languages/python`. None has an upper bound. Dependabot's `uv` entry proposes each new minor or patch release as a lock update. The `wheels` job builds with `PyO3/maturin-action` instead, with maturin's version fixed in the workflow. `python/stackencrypt/_eql.py`, the EQL type markers, is generated from the EQL catalog by `eql-codegen py-eql`. To regenerate it, run `mise run types:generate` in `packages/eql`. Never edit it by hand: `tests-python.yml` runs its parity tests and fails on a hand edit. Design: the Python ADRs under `languages/python/docs/adr/` (ADR-0001, the declaration; ADR-0002, a query names its field by a string; ADR-0003, one method for each query operator; ADR-0004, the SQLAlchemy layer encrypts in batch hooks), the spec in #1341. `languages/python/docs/scorecard.md` marks the eight shared principles of `docs/sdk-design-principles.md` against the code. The README's SQL and Python blocks run in order in the `live` job, through `tests/test_readme_live.py`, so a change to a README step needs that test to pass. +- `languages/python`: The Python SDK, `stackencrypt`, a pyo3 extension over `stack-encrypt`, built by maturin. **The fourth Cargo workspace**, excluded from the root one. It has two crates. `crates/core` has no pyo3: the engine-side logic, linked and tested without a Python interpreter. `crates/engine` is the `_engine` cdylib, `abi3-py39`, one wheel per platform for Python 3.9 to 3.14. `crates/core/fuzz` is a detached cargo-fuzz crate over the value conversion.

It builds the extension and the bundle in a step with no credentials, then runs `mise run test:live:run`, which builds nothing, in the only step that has them. So no dependency's build script runs with the credentials set. The two steps share one runner, though: a file a build step leaves behind, or the extension itself, still runs with them. Building the wheel in a separate job with no secrets would close that gap. Locally, `mise run test:live` does both. It skips on a fork's pull request, and the task fails on any skipped test. A third job, `wheels`, builds one abi3 wheel per FFI platform, uploads them as artifacts, and writes each build time to the job summary. `scripts/__tests__/python-ci.test.mjs` compares its path filter with the workspace's `Cargo.lock` and its wheel matrix with the protect-ffi platform packages. `languages/python/uv.lock` locks the `test` extra: pytest, attrs, Pydantic, SQLAlchemy, psycopg, and Alembic.

It has its own `pyproject.toml` and `uv.lock`, and installs `stackencrypt` from this checkout.

It now reads the statement's own values and refuses any sealed value it cannot encrypt. That also drops a second compile of every write. The session hook froze every ORM result. That broke a joined eager load with unique(), hid SQLAlchemy's refusal of one without it, and read the whole table under yield_per. It now decrypts each chunk of rows as the ORM builds it. A single-table subclass of a configured class is now decrypted as its base. Its load events propagate, and the class is found through the inheritance chain. The rest: a unique index or a primary key on an encrypted column is refused like a unique constraint; a bare encrypted column in a window, WITHIN GROUP, an aggregate's ORDER BY or a UNION's ORDER BY is refused, since it would sort the stored JSON; a MappedAsDataclass relationship needs no marker; a hint resolves in the module's names before the class's, as get_type_hints(cls) does; an index name over 63 bytes is cut short with a hash; and a mixed-case column's own index on its term is found.

fix(python): build and pass the tests on next The rebase onto next brought vitaminc 0.9 and a newer stack-encrypt. The Python workspace did not compile against them, and its tests expected the old catalog. - Re-seed the Python Cargo.lock from the root one, and the fuzz crate's lock from the Python one, so both resolve vitaminc 0.9. - Use vitaminc's Buffer and AsProtectedRef where stack-encrypt now returns and takes them, and Op where OpSpec was removed. - Regenerate _eql.py: the engine now produces Json. The Python declaration still refuses the json kind, so the tests that needed an unproducible marker or an unexported one now make one, and the live every-type test leaves out the whole json kind. - Let the EQL suite CI test accept the root workspace in a rust-cache step, as tests-golang.yml's wasi-check names it. - Skip the encrypt and query heap tests as known failures. stack-encrypt's dispatch now boxes futures built on the stack, which copies plaintext the caller left there into a heap block that it frees unwiped (#1644).
