Adds docs/sdk-design-principles.md: eight principles for every language SDK and thirteen for the Go SDK. ADR-0002 records the decision to adopt them, and AGENTS.md points agents at the document before they design or change a language SDK. Why write them down. The Go design in #1070 was settled one objection at a time: the result type, a forgotten call, a field looked up by string, a check at startup. Each fix reopened the same questions. When is a mistake found? What does the user see? What must match across languages? Without an answer on the page, the next language SDK would argue all of it again. How they were set. Each principle was reviewed and accepted one at a time, and several were changed in review: - "Find mistakes at compile time" gained a fixed order of stages, so the three cases Go cannot catch in the compiler do not read as violations. - "Mirror the Rust concepts" became "take the host language's shape". The plan is hidden from a Go user altogether, which goes further than reshaping its calls. - "One way to do each thing" replaced a package function, an interface and a marker method with generated functions in the user's package. - Dave Cheney's API advice is an input and not a named source. Two rulings already depart from it: a slice parameter in place of a variadic one, and package-level generated values. Why two terms. "Binding" was being used for the user-facing library and for the interface to the engine. They are different things with different rules, so the document fixes one word for each. Why an order for conflicts. Go idiom and compile-time guarantees pulled against each other more than once. The order says which wins: the engine and the bytes, then early checks, then hiding what a user cannot act on, then idiom. Five questions are listed as not yet decided. The largest is the approach of the Go policy package. The text follows ISO 24495-1 and ASD-STE100 and passes slipstream's language, length and line-break checks with 0 findings. The script tests that read AGENTS.md were not run here: this worktree has no node_modules. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi

A review of #1070 found claims that disagreed with decisions on #1052. This commit settles the ones that have a ruling. A field crosses the binding only when its value does. The section said generated code sends the full declaration and skips passthrough values. Decision 9 of the plan says every plan field must be present in the value. Agreed with Dan: a field with no value sends no declaration, so decision 9 holds and the data grammar does not change. The generated file still names every field, because that file is what a reviewer reads. The record fixture replaces the golden snapshots as the proof of the lowering. Sequencing item 7 rested on plantest.Golden, and this design removes the package that writes those snapshots. The fixture compares term bytes and checks that each side opens the other's records, because a ciphertext is not the same bytes twice. The sentence about #1025 is gone: it merged. The generator checks a declaration with the embedded guest. A second copy of the engine's rules in stashgen is the "lives twice" cost that ADR-0007 accepted only for an encoder. It was an open question. The EQL envelope is stated. eql-bindings writes the eql_v3 types with SchemaVersion 3 and a ciphertext prefixed "stack-encrypt:1:", and its module doc says the envelope and SQL domains are unchanged. "EQL v4" in the plan names that form. Principle 5 forbade a single-value form while a field entry's Encrypt takes one value. The exception is now written. The principles ADR moves to the stack-encrypt series as ADR-0008. docs/adr/0002 and packages/stack-encrypt/docs/adr/0002 were two different ADR-0002s, and this ADR rests on ADR-0007 in that series. The glossary gains Binding, Language SDK and Declaration, which the principles define and the glossary used loosely. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi

…ed context Two more items from the review of #1070. encrypt.Batch is removed, with EncryptInto, DecryptInto and Operation. One ZeroKMS request for several types needs the guest to take several declarations in one call: se_encrypt_record takes one plan today. It also needs the engine to run several plans under one key request, and Dan confirmed that the Rust side does not exist. A design that names a call the engine cannot serve is a claim that was not run. The work is listed as an open question, and the Go call is designed after it. The Go SDK has no cipher-directed path, and the plan now says so. An opaque struct goes to the engine with a declaration, so a sealed value always has a declared context, and Cipher.Extend appends to that context. A call that takes its own context lets the write and the read disagree, which principle 4 forbids. The glossary said cipher-directed is the one path every binding has natively; that sentence is amended, and ADR-0008 records the consequence. The guest's value exports have no caller in Go. Principle 7 keeps history out of a design document, and this plan holds "Why the first draft was dropped" and the rejected names. The principle keeps its text. The move of that history to ADR-0007 is an open item that Dan owns, because those sections are his. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi

The review of #1070 found four ADRs whose text the Go SDK design leaves wrong. Each gets a dated amendment, and each amendment names the principle it rests on, so a reader can trace the change back. ADR-0007 gains the binding and language SDK words, the rule that a field crosses the binding only with its value, the record fixture as the proof of the lowering, the generator checking declarations with the embedded guest so the engine's rules have one source, and the fact that the guest takes one plan in one call. The value exports stay for another host of the guest and are not a Go path. ADR-0005 decision 4 named bindings/go, stackencrypt and stackauth. The module is at languages/golang and the packages are encrypt and auth. ADR-0006 said the Go binding has a Label held to Rust's by a fixture. The Go SDK has no Label: the segments come from the context= tag and the field name, and the engine's own parser checks them at go generate. The Go half of the fixture is retired with the Go Label. ADR-0004 decision 5 is convention in Rust and structural in Go, because Go has no standalone term derivation. Decision 6's plan-versus-value check moves to go generate for Go, with the engine's check as backstop. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi

Decisions from discussion with @coderdan, 2026-10-05 (PDT)Responses to the decisions comment above. Dan's proposal in "EQL Plans in Go" is taken. The plan names the EQL type. The guest runs the Rust plan for that type and returns the finished EQL value. Go does not assemble EQL values. The two conditions stand: the
Changed. The whole struct crosses the binding to the engine and back, passthrough fields included. This is heavier on the wire. It needs less reconstitution on either side, so the code stays simpler and easier to understand.
Deferred until later. It is not an open question.
Remove
Edit the earlier ADRs. Each gets a note that says a later ADR changed the decision.
Re-scope CIP-4157 to the three sqlc rules.
No action now on CIP-4319. Dan's audit-context and lock-context PRs, sequencing item 10 in the plan, address it. Note This feedback was written with assistance of Claude Code, with 4 reviews and 3 corrections. |

Five decisions from a discussion with Dan Draper, recorded on #1070. The guest returns the EQL value. The data plan names the EQL type as a target, and the guest build that holds the EQL types runs that type's own Rust plan and returns the finished value. Go stores it and assembles nothing, so the EQL encoding lives once, in eql-bindings, and the EQL fixture has nothing to test. Two guest builds: encrypt embeds the one without the EQL types, encrypt/eql embeds the one with them, and a generated file that names an EQL type imports encrypt/eql, so the link is forced by code the user compiles. The size of the larger build is measured before the SDK ships two builds or one. This reverses one bullet of ADR-0007; the amendment and the "EQL v4 types as field targets" section say so. WithGuest joins the Removed list, because with it a program could link the smaller build beside EQL types and fail at run time. The whole struct crosses the binding, both ways. Passthrough fields cross with their values and come back. Heavier on the wire; nothing is rebuilt from parts on either side, so generated code is simpler. Decision 9 of the plan holds. The generated examples send every field and read every field back. One request for several types is deferred, not open. It moves from "Open questions" to a "Deferred" section. se_encrypt and se_decrypt are removed, not kept for a host that does not exist. Each amended ADR opens with a note that a later ADR changed the decision, so a reader of ADR-0004 to ADR-0007 sees the change before the body.

Adds docs/plans/2026-10-04-plan-builder/: complete Go programs that use
the Go binding the plan describes, with a README that lists what each
file shows.
Why complete programs: a snippet hides the questions a Go caller asks
first. Where does the plan live? What type does each call return? How
does a value reach a database column? Each file answers them in context.
Why three database stores: database/sql, GORM and sqlc are the usual
ways Go code reaches Postgres. Each store encrypts before the driver
sees a value, because driver.Valuer gets no context.Context and runs
one field at a time, so it can neither batch a ZeroKMS request nor stop
on cancellation.
The sqlc packages are real `sqlc generate` output (sqlc v1.31.1, sha256
checked against the release asset digest). Running it confirmed three
things the examples rely on:
- go_struct_tag works on a column override that has no go_type;
- the params structs carry the stash tags, not only the model;
- userdb.CreateUserParams(row) converts from the generated model.
The EQL sqlc variant records what running sqlc against EQL showed:
- sqlc cannot parse the EQL install bundle. A bisection over its 6,434
statements stopped at line 2829, an eql_v3_internal."-" overload that
differs from its sibling only by text versus text[]. Two plain
functions, minus(jsonb, text) and minus(jsonb, text[]), reproduce
`relation "minus" already exists`. Quoting and DO blocks are not the
cause. The workaround is a file that declares the domains for sqlc.
- A db_type override matches only the exact spelling in the schema:
public.eql_v3_text_search and eql_v3_text_search are two spellings,
and the wrong one leaves the column as interface{}.
- sqlc types a parameter by its first cast, so the query casts once,
straight to the query domain. $1::jsonb::eql_v3.query_text_search
generates json.RawMessage.
The interface does not exist yet, so nothing here builds in this
repository. Every Go file type-checks (`go vet ./...`) against a
signature-only stub of the proposed API, with real gorm.io/gorm v1.31.2
and github.com/jackc/pgx/v5 v5.11.0, and gofmt reports nothing. The stub
is not committed.

Replaces "The Go mirror" with "The Go binding" and brings the intro, decision 2, the other-languages table, sequencing step 5 and the open questions in line with it. The plan states the design; the reasons are here. Typed plans are the design, not an open question. The mirrored chain ended in one Run(ctx) on one builder type, and Go methods cannot take type parameters. So Run could only return `any`: cipher.Encrypt(user).Using(p).Run(ctx) and cipher.Encrypt(users)... share a builder type and differ only at run time. Every caller would assert a type, as probe.(stackencrypt.EqualityTerm) does today. A method on a generic type can use the type's parameter, so RecordPlan[T], RowPlan[T, R] and ValuePlan[T] return a concrete type from every call. Using(p) cannot be overloaded for a one-value plan and a record plan. ValuePlan[T] is both a standalone one-value plan (the Rust age_plan) and one field of a record plan (Field[V]), so queries and one-column updates are typed as well. Calls that could fail silently now fail loudly or do not compile: - A slice meant a batch by reflection, which is ambiguous ([]string is one value or two; []byte is worse). EncryptAll and DecryptAll say so. - Discarding a builder compiles and go vet is silent, so a forgotten .Run(ctx) after .Into(&user) decrypted nothing. Every call returns its result. - TermKind is a uint32: it cannot carry Match or JSON options, and TermKind(42) compiles. Index is an interface only stackencrypt implements. - EncryptIndex(name, first Index, rest ...Index) makes an empty index set a compile error (Dave Cheney's required-first variadic), as `()` not implementing Indexes does in Rust. A policy that computes an empty slice would otherwise drop the index with no error: the #1051 failure. - An EncryptedRecord map lookup with a typo returned a zero value, and the insert wrote NULL. Field(name) returns ErrUnknownField. - An untagged struct field was left out of the record with no error. PlanOf refuses an exported field with no stash tag. - RowPlan[T, R] checks a storage struct (hand-written, a GORM model or an sqlc model) against the plan at init. A column added without an override panics at startup instead of storing plaintext. Go idiom: - ctx is the first parameter and is never stored, as the context package asks. A .Context("users") chain method read as context.Context (r.Context(), the Google API clients' .Context(ctx).Do()), and the package already has a Context type. The context is now an argument to NewPlan, NewValuePlan or Cipher.Encrypt, or the context= tag. - The inline .Fields() chain on Encrypt is gone. It rebuilt and checked the plan on every call; a plan is now a package-level value built once. - Builder methods return a new builder, so two chains from one base cannot share state. A built plan never changes and goroutines share it. - PlanOf returns an error, because a tag can fail to parse, and MustPlanOf panics for package-level variables, as plan.MustPlanFor does. - Errors are a *PlanError wrapping sentinels, for errors.Is and errors.As. An error never holds a plaintext value, because a fail-closed error names a field and a careless %v would print it. Storage: - EncryptedField.Ciphertext was `any`, which is not a driver.Valuer. Ciphertext is one concrete type that implements driver.Valuer and sql.Scanner. A scalar column can hold any of the four Sealed leaf kinds, so one storage type replaces them. - Decrypter keeps both decrypt behaviours the binding has today: a *Client opens a leaf under any of its keysets, and a *Cipher refuses a leaf from another keyset with ErrForeignKeyset. - The tags used `plain` for a field left out of the record, beside a Passthrough verb that carries a field unsealed. The tags now use the verbs: passthrough, and `-` for Omit. - The policy package's Plaintext decision becomes an Omit field, so Bind accepts the struct under the fail-closed rule. A batch across plans stays an open question. The draft spelled it Prepare, which reads as database/sql's PrepareContext; the question now records the typed-handle shape instead. The new text follows ISO 24495-1 and ASD-STE100, one sentence to a line, and passes slipstream's guide-language, guide-length and line-break checks: 0 findings, 93 sentences, the longest 24 words, a deviation of 5.06. Paragraphs this change does not touch keep their wrapping. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Makes a generated type the main Go path for a struct with stash tags. The plan states the design; the reasons are here. The goal is a concrete output type that matches the input type, checked by the compiler. Go has three ways to write that type's shape (generate it, write it by hand, or hold both states in one type) and two ways to connect it to the plaintext type (generics, interfaces). Neither generics nor interfaces can write the shape: Go generics substitute types and cannot derive one struct from another, and an interface describes methods, not fields. Why generate: the type and the plan come from the same tags, so they cannot disagree, and every check moves to compile time. A hand-written type is checked against the plan only at package init. One type that holds plaintext before Encrypt and ciphertext after was rejected: a forgotten Encrypt is found only when the driver reads the value, and a log line prints whatever the field holds at that moment. Why each field holds only its declared outputs: EncryptedField has a slot for every index type, and a slot the plan does not declare is nil. Reading it compiled and wrote NULL. EncryptedUserEmail has no Ore field, so the mistake does not compile. UserFields closes the same gap for queries: UserFields.Email has no Ore method. Why the Planned interface: a StashPlan method on User and on EncryptedUser lets stackencrypt.Encrypt and stackencrypt.Decrypt infer the result type from the value. The caller names no plan, so a value cannot be paired with the wrong one. Go 1.26 infers the type through the method for a value and for a slice; the examples compile with it. Why go generate, and a Go command: a Go module that needs Node to build is a poor fit, so stashgen lives in the Go module and runs with `go tool`. This is the easyjson, msgp and gorm.io/gen direction (a Go type is the source of truth), not sqlc's (SQL is). Why RowPlan stays: an sqlc model or a GORM model is owned by another tool, so stashgen cannot write it. NewRowPlan now also accepts a struct field that holds all of one field's outputs, which is the layout the generated type uses, so the generated file needs no second mechanism. RowPlan.Record() lets the GORM and sqlc stores build their row plans from the generated plan. A protobuf message cannot carry tags; a protoc plugin front end is recorded as an open question. stashgen does not exist, so users/user_stash.go is written by hand as the file it will write. The Go files type-check (`go vet ./...`) against the uncommitted stub of the proposed API, and gofmt reports nothing. The amended text passes slipstream's language, length and line-break checks with 0 findings (117 sentences, the longest 24 words). Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
A fact carries two names for one field, Field and GoField, and the example gave no reason for the second. Field is the schema's name, which rules match on and which names the column. GoField is the Go struct field that holds the value, which the generator reads from and reuses as the name of the encrypted type's field. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Adds docs/sdk-design-principles.md: eight principles for every language SDK and thirteen for the Go SDK. ADR-0002 records the decision to adopt them, and AGENTS.md points agents at the document before they design or change a language SDK. Why write them down. The Go design in #1070 was settled one objection at a time: the result type, a forgotten call, a field looked up by string, a check at startup. Each fix reopened the same questions. When is a mistake found? What does the user see? What must match across languages? Without an answer on the page, the next language SDK would argue all of it again. How they were set. Each principle was reviewed and accepted one at a time, and several were changed in review: - "Find mistakes at compile time" gained a fixed order of stages, so the three cases Go cannot catch in the compiler do not read as violations. - "Mirror the Rust concepts" became "take the host language's shape". The plan is hidden from a Go user altogether, which goes further than reshaping its calls. - "One way to do each thing" replaced a package function, an interface and a marker method with generated functions in the user's package. - Dave Cheney's API advice is an input and not a named source. Two rulings already depart from it: a slice parameter in place of a variadic one, and package-level generated values. Why two terms. "Binding" was being used for the user-facing library and for the interface to the engine. They are different things with different rules, so the document fixes one word for each. Why an order for conflicts. Go idiom and compile-time guarantees pulled against each other more than once. The order says which wins: the engine and the bytes, then early checks, then hiding what a user cannot act on, then idiom. Five questions are listed as not yet decided. The largest is the approach of the Go policy package. The text follows ISO 24495-1 and ASD-STE100 and passes slipstream's language, length and line-break checks with 0 findings. The script tests that read AGENTS.md were not run here: this worktree has no node_modules. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Rewrites the Go section of the plan and every example to follow docs/sdk-design-principles.md. The plan states the design; the reasons are here, one for each change. The user never sees a plan. A program now calls generated functions in its own package: users.Encrypt, users.Decrypt and users.Fields. That removes stackencrypt.Encrypt, the Planned interface, the StashPlan methods and the exported plan variables. The package function could not serve a type from another package or a model, so it needed a second call shape beside it; a plan variable put "plan" at every call site. Generated functions give one call shape for all three cases, add nothing to the user's types, and only generated code can provide them. A -name flag tells two structs in one package apart. One EQL column for each field leads. encrypt_into names an EQL type and the generated field holds one value. The generated type is then flat, so database/sql, pgx, sqlx and GORM take it as it is, and sqlc's row struct converts to it directly. Separate columns stay as the second layout, with a model named by -record (the flag was -row, and the term was "storage struct"). Every sealed field gets its own struct in the separate-columns layout, including a field with one output. Flattening meant that adding an index later changed how every caller read the field. An opaque struct replaces Cipher.Encrypt and DecryptValue. Sealing a whole value was the last call that took a context by hand and returned an untyped ciphertext. As a tag, the context is checked by the generator and the write and the read cannot differ. Context extension moves to the cipher. Passed on each call, it could be left off the query, which then matched nothing with no error. Batch2 and Batch3 put two or three types in one ZeroKMS request. Batching across types is part of the value of the product, so it is in the design and no longer an open question. Go has no variadic generics, so there is one function for each count. Fail closed is spelled out for three cases: one tag on an embedded struct decides for all its fields, and the generated type embeds the same struct so its own tags still apply; other libraries' tags are copied; an unexported field with no tag is ignored with three notices, and stash:"-" states the choice. Printing. Generated types hide their sealed fields. For the struct the user wrote: a generator warning, a run-time warning, a -redact flag, and a go vet check. The full declaration crosses the binding, with only passthrough values skipped. The last commit left passthrough fields out of the declaration, which hid them from the engine. The examples change to match. The blocklist example and the separate-columns sqlc example are removed; accounts (embedded struct, unexported field, -redact) is added; documents is an opaque struct; contacts shows a type from another package with separate columns and a model. Six open questions replace the old one. The EQL package name, its type names and the values of encrypt_into are placeholders until #1062. Checked. Every Go file passes `go vet ./...`, and the generate program passes under `-tags stashgen`, against the uncommitted stub of the SDK; gofmt reports nothing. Seven mutations each fail `go build` as the design says: a field added to the tagged struct, to the model, and to crm.Contact; a column type changed in sqlc's row struct; a generated file from another version; a read of an undeclared output; a field added to Individual. The generate program still builds in that last case. The README lists what was run and what was not. The amended text passes slipstream's checks with 0 findings (214 sentences, the longest 24 words), and every relative link resolves. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
The flag that names a model was -record. The plan's glossary defines Record as the value sealed field by field, which is the generated type, so the flag named the wrong thing. The docs already call the struct a model, and the flag now uses the same word. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Batch2 and Batch3 put two or three types in one ZeroKMS request, with one numbered function for each count. Go cannot write one function that takes any number of differently typed arguments and returns each result with its own type, so the count was in the name. That stopped at three and looked like nothing else in Go. Batch takes any number of operations. Each operation names the variable that gets its result, as rows.Scan and json.Unmarshal do, and the compiler checks the variable's type. The generated functions are EncryptInto and DecryptInto. A batch object that a caller queues work onto and then runs, as pgx has, was not used: a caller can forget to run it, and this design removes that kind of mistake everywhere else. The examples pass go vet against the stub, and the seven mutation checks give the same results as before. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Settles the Go EQL names, and makes the examples show an EQL type the engine can produce. The plan states the design; the reasons are here. The names. The EQL catalog (packages/eql/crates/eql-domains) is the single source of every EQL type, and one function in it turns a domain into a type name for the Rust and TypeScript generators. The Go types take the same names, so TextEq is TextEq in every language. The package is stackencrypt/eql, a query type is the name plus Query, and the value of encrypt_into is the Go type name. The last commit marked all of this as a placeholder waiting on someone else. It was not: the names already existed in the repository. JSON is the one exception. The catalog says Json and Go convention says JSON. Go idiom wins here, because a Go reader meets this name in every struct that uses it. eql-codegen writes the Go package from the catalog, as it writes the Rust and TypeScript types. A hand-copied list of eleven families and their suffixes would drift. Two errors, found by reading the catalog: - The users example declared the wrong terms. It gave TextSearch equality, ORE and match, and IntegerOrd equality and ORE. The catalog says TextSearch is equality, OPE and match, and IntegerOrd is OPE alone. Those were written from memory. - The examples used four EQL types the engine cannot produce. eql-codegen lists the domains stack-encrypt can encrypt into, and the list has one entry: text equality. The others wait on plaintext encodings for the non-text families, and on ordering and match terms in EQL's form. So the plan now says which EQL type works today, stashgen refuses the rest, and the users example is rebuilt on TextEq: two TextEq fields and one search by email. A field that needs an ordering or a match search today uses separate columns, which the contacts example shows. The "Go EQL names" open question is removed, because it is decided. Every Go file passes `go vet ./...` against the uncommitted stub, and the generate program passes under `-tags stashgen`; gofmt reports nothing. The seven mutation checks give the same results on the rebuilt files. The sqlc package is real output for the new schema. The amended text passes slipstream's checks with 0 findings, and every relative link resolves. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
The last commit said separate columns support an ordering or a match search today, and said the EQL types wait on ordering and match terms in EQL's form. Neither was checked against the engine. Both are now. What the source says: - stack-encrypt derives four terms today: equality, match, CLLW ORE and CLLW OPE (packages/stack-encrypt/src/sem/mod.rs). The existing Go package returns all four (stackencrypt/term.go). So separate columns do work today for those searches. - EQL stores a block ORE term (ore_block_256) for OrdOre and SearchOre. The engine's ORE term is CLLW ORE, a different algorithm. So those two EQL types need more than wiring. - EQL's OPE term is CLLW OPE, the family the engine already derives, and its match term is a bloom filter, which the engine also derives. No EQL type is built from them yet: eql-codegen lists one domain that stack-encrypt can encrypt into, text equality. The plan now gives the reason for each group of EQL types, in place of one general sentence. The plan also states that stackencrypt/eql is a package in the Go module. That answers the open question about a package or a separate module, so the question is removed. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
The Go SDK's package was stackencrypt. A caller writes the package name at every use, and the generated code names it in every signature: stackencrypt.Cipher, stackencrypt.Batch. The first half repeats what the import path already says, github.com/cipherstash/stack. The package is now encrypt, with its EQL types at encrypt/eql and the support for generated code at encrypt/gensupport. The plan lists the old name under Removed, so a reader of the existing module can match the two. The examples pass go vet against the stub, the seven mutation checks give the same results, and the sqlc package is regenerated for the new import path. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
The sibling of the encrypt package was stackauth. It is renamed auth for the same reason: the import path already says cipherstash/stack, and a caller writes the package name at every use. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Re-evaluates the policy package against the SDK design principles and keeps it, with five changes. The plan states the design; the reasons are here. Why keep it. Read from the code alone, the package had no user: its only importers were its own tests, and no real source of facts existed. On that evidence the recommendation was to remove it. There is a real user. Their types are generated from protobuf, so they cannot carry tags, and their schema already holds a data category for each field. A declaring struct for each message would mean writing every message a second time by hand. So the policy serves a need tags cannot meet, which is the first of the four tests for a second way in. Why change it. A real user does not fix the ways the package broke the principles: - A quiet path to plaintext. A field with no annotation that no rule named was "left out of the plan and stored as it is", with no error. With tags the same field stops the generator. Every field of a message now needs a decision, and a catch-all exists only when its author writes one. - The word "plan". The package is encrypt/policy. Its decisions are the tag verbs (Encrypt, EncryptIndex, Index, EncryptInto, Passthrough, Omit), so a rule and a tag say the same thing in the same words. Plaintext becomes Passthrough, Column becomes Name, Table becomes Context. - A source of facts. A policy with no source does nothing. The plan names encrypt/policy/protosource, which reads a protobuf descriptor and its field options. - The build constraint. The last design put the generated file in the type's own package, so the generate program imported a file it had written, and a stale file stopped it from building. That needed a build tag and a rule about where other code could live. Generated functions do not need to live beside the type. For this user the type is in a package protoc writes, so the output goes in a package of their own, and the problem is gone. - Tags or a policy, with a stated line between them: tags for a type you write, a policy for a type a schema generates. Kept from the package: Identity, which holds a field's context when its column gets a new name. Tags have no word for that yet, and the open question on changing a declaration now says so. The example is rebuilt on real protobuf code. proto/ holds a message whose fields carry a data_categories option, and buf v1.50.0 with protoc-gen-go wrote internal/pb. The generated file for it compiles against that code, which confirms two statements in the plan: Go cannot convert a protobuf message to a copy of its fields, and a field added to the message does not stop the build, so CI finds that change. Not run: the protobuf source and the rules themselves. Neither the source nor the generator exists. Every Go file passes `go vet ./...` against the uncommitted stub, and gofmt reports nothing. The amended text passes slipstream's checks with 0 findings, and every relative link resolves. Refs #1046 Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
A review of #1070 found claims that disagreed with decisions on #1052. This commit settles the ones that have a ruling. A field crosses the binding only when its value does. The section said generated code sends the full declaration and skips passthrough values. Decision 9 of the plan says every plan field must be present in the value. Agreed with Dan: a field with no value sends no declaration, so decision 9 holds and the data grammar does not change. The generated file still names every field, because that file is what a reviewer reads. The record fixture replaces the golden snapshots as the proof of the lowering. Sequencing item 7 rested on plantest.Golden, and this design removes the package that writes those snapshots. The fixture compares term bytes and checks that each side opens the other's records, because a ciphertext is not the same bytes twice. The sentence about #1025 is gone: it merged. The generator checks a declaration with the embedded guest. A second copy of the engine's rules in stashgen is the "lives twice" cost that ADR-0007 accepted only for an encoder. It was an open question. The EQL envelope is stated. eql-bindings writes the eql_v3 types with SchemaVersion 3 and a ciphertext prefixed "stack-encrypt:1:", and its module doc says the envelope and SQL domains are unchanged. "EQL v4" in the plan names that form. Principle 5 forbade a single-value form while a field entry's Encrypt takes one value. The exception is now written. The principles ADR moves to the stack-encrypt series as ADR-0008. docs/adr/0002 and packages/stack-encrypt/docs/adr/0002 were two different ADR-0002s, and this ADR rests on ADR-0007 in that series. The glossary gains Binding, Language SDK and Declaration, which the principles define and the glossary used loosely. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
…ed context Two more items from the review of #1070. encrypt.Batch is removed, with EncryptInto, DecryptInto and Operation. One ZeroKMS request for several types needs the guest to take several declarations in one call: se_encrypt_record takes one plan today. It also needs the engine to run several plans under one key request, and Dan confirmed that the Rust side does not exist. A design that names a call the engine cannot serve is a claim that was not run. The work is listed as an open question, and the Go call is designed after it. The Go SDK has no cipher-directed path, and the plan now says so. An opaque struct goes to the engine with a declaration, so a sealed value always has a declared context, and Cipher.Extend appends to that context. A call that takes its own context lets the write and the read disagree, which principle 4 forbids. The glossary said cipher-directed is the one path every binding has natively; that sentence is amended, and ADR-0008 records the consequence. The guest's value exports have no caller in Go. Principle 7 keeps history out of a design document, and this plan holds "Why the first draft was dropped" and the rejected names. The principle keeps its text. The move of that history to ADR-0007 is an open item that Dan owns, because those sections are his. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
The review of #1070 found four ADRs whose text the Go SDK design leaves wrong. Each gets a dated amendment, and each amendment names the principle it rests on, so a reader can trace the change back. ADR-0007 gains the binding and language SDK words, the rule that a field crosses the binding only with its value, the record fixture as the proof of the lowering, the generator checking declarations with the embedded guest so the engine's rules have one source, and the fact that the guest takes one plan in one call. The value exports stay for another host of the guest and are not a Go path. ADR-0005 decision 4 named bindings/go, stackencrypt and stackauth. The module is at languages/golang and the packages are encrypt and auth. ADR-0006 said the Go binding has a Label held to Rust's by a fixture. The Go SDK has no Label: the segments come from the context= tag and the field name, and the engine's own parser checks them at go generate. The Go half of the fixture is retired with the Go Label. ADR-0004 decision 5 is convention in Rust and structural in Go, because Go has no standalone term derivation. Decision 6's plan-versus-value check moves to go generate for Go, with the engine's check as backstop. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
Five decisions from a discussion with Dan Draper, recorded on #1070. The guest returns the EQL value. The data plan names the EQL type as a target, and the guest build that holds the EQL types runs that type's own Rust plan and returns the finished value. Go stores it and assembles nothing, so the EQL encoding lives once, in eql-bindings, and the EQL fixture has nothing to test. Two guest builds: encrypt embeds the one without the EQL types, encrypt/eql embeds the one with them, and a generated file that names an EQL type imports encrypt/eql, so the link is forced by code the user compiles. The size of the larger build is measured before the SDK ships two builds or one. This reverses one bullet of ADR-0007; the amendment and the "EQL v4 types as field targets" section say so. WithGuest joins the Removed list, because with it a program could link the smaller build beside EQL types and fail at run time. The whole struct crosses the binding, both ways. Passthrough fields cross with their values and come back. Heavier on the wire; nothing is rebuilt from parts on either side, so generated code is simpler. Decision 9 of the plan holds. The generated examples send every field and read every field back. One request for several types is deferred, not open. It moves from "Open questions" to a "Deferred" section. se_encrypt and se_decrypt are removed, not kept for a host that does not exist. Each amended ADR opens with a note that a later ADR changed the decision, so a reader of ADR-0004 to ADR-0007 sees the change before the body. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi
…e engine returned The plan says the whole struct crosses the binding both ways and nothing is rebuilt from parts on either side. The generated examples still copied passthrough fields from the Go value into the encrypted type, so one side rebuilt. Seal now takes only the record the engine returned, reads each passthrough field from it, and returns an error for a value of the wrong type rather than asserting. The README row that said generated code assembles EQL types says the guest returns them. Claude-Session: https://claude.ai/code/session_014jiJy4WhYH2LXojK2jSoxi

- Around line 1178-1180: Update the design around `WithGuest` to account for
overrides that replace the embedded wasm guest with a non-EQL module. Require or
validate that any guest override used with an EQL target is EQL-capable; do not
treat importing `encrypt/eql` as sufficient to make target refusal unreachable.
- Around line 690-691: Update the print-method contract for EncryptedUser to
specify that `%#v` redacts sealed fields, using GoStringer or Formatter as
appropriate, and add a focused test that verifies this format hides sealed
values.
- Around line 1223-1224: Update the EQL typed verb sequencing entry to state
that Go names the EQL type as a target in its data plan and generated code
stores the value returned by the guest; remove the inaccurate claim that Go
assembles EQL types through the generator.
Review comments at @docs/plans/2026-10-04-plan-builder/README.md:
- Line 11: Update the main.go row in the README table to describe one call for
each type, rather than a batch of two types in one request.
Review comments at @docs/sdk-design-principles.md:
- Around line 76-77: Scope the request-count principle to SDK calls that use the
key service, and update the related “Each call sends one request” statement in
the Go plan to apply only to calls that use ZeroKMS. Keep the existing call and
request-count examples otherwise unchanged.
- Around line 79-82: Update the cross-type batching principle to make it
conditional on the engine supporting multiple plans per request and the binding
accepting multiple declarations; clarify that the Go SDK defers this capability
until those requirements are met.

Account for WithGuest when selecting the EQL guest.
WithGuest replaces the embedded wasm module. A caller can therefore use an EQL target with a non-EQL guest, which may refuse that target. Update the design to require or validate an EQL-capable override; importing encrypt/eql alone does not make the refusal unreachable.

Correct the main.go description.
The table says main.go sends "a batch of two types in one request". main.go Line 61 says "One call for each type, and one ZeroKMS request for each call". The PR objectives also defer multi-type batching. As a result, the README describes behavior that the example no longer shows.

Update the main.go row in the README table to describe one call for each type,
rather than a batch of two types in one request.

Limit the one-request guarantee to calls that use the key service.
The principle promises a key-service request for every SDK call, but the Go plan includes term calls that derive without one. The plan’s later “Each call sends one request” sentence is also too broad. Scope both statements to key-service calls.
Suggested fix
diff --git a/docs/sdk-design-principles.md b/docs/sdk-design-principles.md
-One call from the user makes one request to the key service, however many values it carries.
+A call that uses the key service makes one request, regardless of how many values it carries.
diff --git a/docs/plans/2026-10-04-plan-builder.md b/docs/plans/2026-10-04-plan-builder.md
-Each call sends one request, so two types take two calls and two requests.
+Each call that uses ZeroKMS sends one request, so two types take two calls and two requests.📝 Committable suggestion

Scope the request-count principle to SDK calls that use the key service, and
update the related “Each call sends one request” statement in the Go plan to
apply only to calls that use ZeroKMS. Keep the existing call and request-count
examples otherwise unchanged.

Scope cross-type batching to multi-plan engine and guest support.
The shared principle says an SDK can put operations on different types in one request. The Go plan sends one request per type: each call carries one declaration, and multi-type requests are deferred until the engine and guest support multiple plans per request. Add this condition so the principle does not read as a current Go capability.
Suggested fix
-- An SDK can put operations on different types in one request.
+- An SDK can put operations on different types in one request when its engine can run multiple plans under one key request and its binding accepts multiple declarations. The Go SDK defers this until then.📝 Committable suggestion

supporting multiple plans per request and the binding accepting multiple
declarations; clarify that the Go SDK defers this capability until those
requirements are met.
