Worker JSON-facing adapters can request +bounded text or binary chunks through this same contract, but Tools/WIP and +model-context/image presentation belong to T-723; this API does not emit large +base64 JSON blobs. + +Downloads validate bare MIME types and always use `Content-Disposition: +attachment` with percent-encoded UTF-8 names, `nosniff`, a sandbox/default-none +CSP, `private, no-store`, and a Workspace/node/revision ETag. Arbitrary HTML/SVG +bytes are storable, not safe app-origin inline previews. Content length is exact; +if a later chunk loses authority or expires, the response stream fails rather +than returning another generation or a successful truncated file. Even an empty +file validates its referenced blob before HTTP success. Conditional 304/range +HTTP semantics are not added; revision-selected chunk reads are explicit. + +Errors use fixed, path-free typed codes: `denied`, `not_found`, `conflict`, +`invalid`, `limit`, `storage_unavailable`, `outcome_unknown`. SQL/commit/task +uncertainty at a mutation boundary is `outcome_unknown`/`unknown`; known rejection +or blob persistence failure is `not_committed`. A successful DB commit alone +returns a mutation response. After a lost response, query the same request ID; +`uncommitted` only means no committed receipt in that snapshot and must not be +interpreted as proof that an in-flight request can never commit. Exact replay uses +the same identity/payload/transport-bound actor and current permissions. Never +blindly create a fresh request ID to resolve an unknown outcome. Physical paths, +blob keys and raw provider errors are not public. + +Contract regeneration/freshness: + +```sh +cargo run -q -p server-api --example export_openapi -- openapi/server-api.json +cargo run -q -p server-api --example export_openapi -- --check openapi/server-api.json +cargo run -q -p server-api --features typescript --example generate_drive_api_types > web/workspace/src/lib/generated/drive-api.ts +deno fmt web/workspace/src/lib/generated/drive-api.ts +cargo test -p server-api --features typescript generated_drive_api_contract_is_current +# Existing OpenAPI-derived projections embed the whole-contract digest: +for example in generate_repository_openapi_types generate_runtime_api_types generate_ticket_api_types generate_companion_api_types generate_worker_launch_api_types; do + cargo run -q -p server-api --example "$example" + cargo run -q -p server-api --example "$example" -- --check +done +``` + +The existing BinaryBody contract also supports binary **success responses**, +including declared response headers, without changing binary request bytes or +JSON/error behavior.

Its Read calls using repository-relative logical paths could +not read the required testing strategy; absolute paths were rejected as invalid +logical paths too.

It produces and consumes framework-neutral `wip-http` messages but performs no network I/O and contains no UI types. + +```toml +[dependencies] +wip-client = "0.1.0" +``` + +Applications provide the HTTP adapter and presentation layer, send each prepared request exactly as owned by the runtime, then return the corresponding response for completion. + +## Interface identity and scope lifetime + +Interface acquisition and call APIs use `wip_protocol::InterfaceReference { scope, name }` directly. Within an endpoint/security-context session, the complete scoped pair is the cache key and the Object membership key: equal names in different scopes remain distinct. A scope is a canonical absolute Worldspace path and must be an ancestor of, or equal to, the call target path. Root scope (`/`) and self scope are valid; clients must not rewrite either into a different reference. + +`InterfaceObservation::scope_ref` is optional opaque metadata identifying the scope Object, not a third reference component, a path, or an Interface Descriptor validator. Its absence does not prevent acquisition or calls. Calls copy the exact observed reference, optional `scope_ref`, and optional Interface Descriptor validator into `InterfaceTarget`; the target Object validator is copied separately. The `CallContext` fixes those observations, the descriptor, and the operation declaration before dispatch. + +A descriptor without an Interface Descriptor validator is immutable only within the lifetime of its scope Object, not forever at that path. Descriptors with validators are also bound to that scope lifetime. When accepted observations establish that a known scope binding has changed or been lost, dependent cached interface state is invalidated and cannot authorize a new call until explicitly reacquired. A superseded interface response must not restore an observation from the old lifetime. A previously prepared call retains its original context rather than silently adopting a new scope identity or descriptor. + +Scope binding evidence is shared across Interface names at the same scope path: a new binding learned by fetching one name retires older descriptors for the other names too. Separately observed Object refs also provide lifetime evidence even when a descriptor's `scope_ref` was omitted. This corroboration is private bounded cache state, not an invented identity, and never fills in missing call metadata. Same-lifetime descriptor validation still applies; a detected ref change or loss retires the old lifetime instead. + +Object deletion, entry-edge removal, and local cache eviction are different events. A direct observe `NotFound` confirms unavailability at the requested scope path and removes cached interfaces scoped to that path; it does not guarantee identity-wide Object deletion or unavailability through every alias. Removing one entry edge likewise does not prove that the Object was deleted or invalidate every remaining alias. Cache eviction is local loss of retained knowledge, not evidence of Host deletion. Losing a known binding at an interface's scope path nevertheless ends safe reuse of descriptors dependent on that binding, even if the same Object remains reachable elsewhere. Optional `scope_ref` can provide identity evidence, but clients do not fabricate it when it is absent. + +Without Object `ref` or `scope_ref` identity evidence, a replacement at the same scope path can be indistinguishable from the previous Object. The runtime cannot detect every ref-less replacement from path and descriptor contents alone; absence of detectable change is not proof that the scope lifetime continued. + +## Explicit recovery and operation outcomes + +`ensure_observed` and `ensure_interface` avoid duplicate fresh or loading work; they do not automatically refresh retained stale or failed observations. Use the explicit object/children refresh APIs and `prepare_interface` to recover the observations required for a new call. An operation `InterfaceMismatch` invalidates both sides of the call's assumptions: it marks the target Object observation stale and invalidates the selected cached interface observation, so recovery requires reobserving membership and reacquiring the descriptor. Reobserving an Object and reacquiring its interface are retrievals, not a retry of an operation. + +The runtime never automatically retries an operation. Mark a call dispatched when handing it to the transport and report completion or transport failure with its original `RequestId`. A timeout, disconnect, or invalid response after dispatch can leave the outcome unknown: execution or commit cannot be ruled out. Refreshing stale state does not resolve that uncertainty and must not automatically resubmit the call; any new operation is an explicit application decision. + +See the [API documentation](https://docs.rs/wip-client) for session, acquisition, cache, and call APIs. + +Licensed under either of Apache-2.0 or MIT at your option. diff --git a/vendor/wip-rs/wip-client/src/lib.rs b/vendor/wip-rs/wip-client/src/lib.rs new file mode 100644 index 000000000..d107bfce3 --- /dev/null +++ b/vendor/wip-rs/wip-client/src/lib.rs @@ -0,0 +1,2325 @@ +//!

Scope must be a canonical absolute Worldspace +path and name must be nonempty. Legacy opaque strings, short-form strings, +relative scopes, missing fields, and extra members are rejected.

It requires no descriptor. +An Interface needs no Object, separate name/scope/context arguments or lookup. +There is no document aggregator, configuration or details selector. + +## Typed display tokens + +```rust +use wip_protocol::{Object, InterfaceReference, InterfaceDescriptor, INTERFACE_FORMAT_V1}; +use wip_text_view::{ + Interface, TokenKind, tokenize_object, tokenize_interface, to_plain_text, + render_object, render_interface, +}; + +let reference = InterfaceReference { scope: "/".into(), name: "example".into() }; +let object = Object { + name: "item".into(), description: None, interfaces: vec![reference.clone()], + r#ref: None, validator: None, +}; +let object_tokens = tokenize_object(&object)?; +assert_eq!(object_tokens[0].kind(), TokenKind::Keyword); +assert_eq!(object_tokens[0].text(), "object"); +assert_eq!(to_plain_text(&object_tokens), render_object(&object)?); + +let descriptor = InterfaceDescriptor { + format: INTERFACE_FORMAT_V1.into(), documentation: None, + types: vec![], operations: vec![], +}; +let input = Interface { reference: &reference, descriptor: &descriptor }; +let tokens = tokenize_interface(&input)?; +for token in &tokens { + // Custom renderers can select presentation by role without reparsing text. + if token.kind() == TokenKind::Reference { + assert_eq!(token.text(), "\"/::example\""); + } +} +let joined: String = tokens.iter().map(|token| token.text()).collect(); +assert_eq!(to_plain_text(&tokens), joined); +assert_eq!(to_plain_text(&tokens), render_interface(&input)?); +# Ok::<(), wip_text_view::RenderError>(()) +``` + +`tokenize_object` / `tokenize_interface` return `Result, RenderError>`. +They generate **directly from the input structure**, not by lexing a completed +Text View string. Each token owns its text (and can outlive the input) and exposes +`kind()` / `text()`. Existing render APIs use the same token generation followed +by `to_plain_text(&[Token])`; there is no second grammar/escape/layout engine. + +### Kind and splitting contract + +| Kind | One token contains | +| --- | --- | +| `Keyword` | One grammar keyword, Object property label, or primitive type keyword | +| `TypeName` | One type declaration name or Named type reference | +| `OperationName` | One Operation declaration name | +| `ParameterName` / `FieldName` | One parameter / record field name | +| `CaseName` | One enum or union case name | +| `String` | One complete quoted Object name or description | +| `Reference` | One complete quoted absolute Interface reference, with both quoting layers | +| `Documentation` | Entire `/// "summary"` content, including marker and internal space, excluding indentation/LF | +| `Symbol` | One punctuation mark, except the indivisible two-character `->` arrow | +| `Whitespace` | One inter-token ASCII space | +| `Newline` | One LF, including the final LF | +| `Indentation` | All leading spaces of a non-root line, two spaces per depth level | + +Quoted identifiers retain their semantic role even when named like keywords. +Quotes, backticks and all WIP escapes are part of the data token, never separate +symbols. Host spaces inside quoted data remain in that token. Adjacent symbols +are separate; no empty tokens or zero-depth indentation tokens are emitted. +`TokenKind` is non-exhaustive so consumers should handle future roles with a +fallback. The API does not distinguish type declaration names from Named uses, +or enum cases from union cases; both share the documented role. + +All layout is included. Concatenate token text **without separators**, not with +`join(" ")`. `to_plain_text` is only that concatenation: no interpretation, +validation, quoting, escaping or layout completion. An empty slice yields `""`; +a filtered/reordered slice is allowed but need not be a complete signature. + +Token text is escaped for **WIP Text View**, not for HTML or other destinations. +Custom renderers must escape for their destination and treat Host text as data, +not markup or instructions. This crate supplies no HTML, ANSI, color or theme +renderer/adapter and no external text lexer/parser or AST. + +## Output and validation + +- UTF-8 plain text with LF, two-space indentation and a final LF, without ANSI, + Markdown fences, syntax highlighting or provider envelopes. Nonempty composites + and parameter lists use multiple lines; layout is deterministic here, but not a + byte-canonical protocol format. +- All Object references remain in Host order. All types, then all operations, + fields, parameters and cases remain in declaration order, without elision. +- Missing vs empty description/documentation, optional vs unit, no payload vs + unit payload, and empty record/enum/union/declaration sets remain distinct. +- Full absolute references use component quoting **and** outer JSON-string quoting. + Identifiers use keywords/backtick rules. All Host strings use standard JSON + escapes plus DEL/C1, Unicode line/paragraph separator and bidi-control escapes. + No normalization, case conversion, URL encoding or input mutation occurs. +- Documentation summaries are displayed in their prescribed positions, including + return documentation between `)` and `->`. Details are not displayed. Host text + is data, not renderer instructions or markup; quoting alone is not a prompt + injection defense. AI adapters must preserve the trust boundary. +- Object ref/validator, children, domain data and Interface scope_ref/validator + are not signature content. No annotations are inferred from operation names. + +The render functions return `Result`; token generation +returns `Result, RenderError>`. Neither returns partial signatures. Resource checks happen first, followed by existing Protocol validators: +Object shape and reference uniqueness, or Interface reference shape plus descriptor +structure, duplicate names, unknown Named references and cycles. Descriptor format +is checked after semantics: valid but unsupported formats return +`UnsupportedDescriptorFormat`, distinct from `InvalidDescriptor`. Supported format +is exactly `wip-interface/1`. Other validation errors preserve the Protocol's typed +`ValidationError` (also exposed as the error source). + +Bounded input limits are **1 MiB** of total string/opaque byte data, **16,384** +declarations/fields/parameters/cases/type expressions/references, **256** named type +declarations, and **64** TypeExpr nesting levels. Details and Object runtime +metadata count toward input bytes even though they are not rendered. A limit +returns `RenderError::ResourceLimit`, never truncates or supplies `...`. Counts +bound allocation and recursive validation before those validators run; these are +library safety limits, not Protocol restrictions. + +Without path/context, this library cannot attest Object scope ancestry, placement, +observation consistency, identity, membership, authorization or currentness. +Callers validate those at their observation boundary. Callers also own retrieval, +resolution, cache, selection, multiple-signature arrangement and AI/UI adaptation. +Text is display-only, not serialization, a digest, identity/cache key or call +target. No parser or round-trip API is supplied. + +## Validation + +`tests/signatures.rs` is an external consumer of the public APIs. Goldens cover +the spec's Object, issue.read, CloseResult, search/return documentation and +identifier examples (with permitted multiline layout), plus nested documentation. +The suite checks all TypeExpr variants/positions, ordering and empty distinctions, +keyword and Unicode names, both reference quoting layers, all required control +escapes, input immutability, metadata exclusion and typed rejection cases. Every +existing case compares the render result (including exact errors) with token +text concatenation and `to_plain_text`. Additional tests assert complete Object +token splitting, all semantic roles, keyword collisions, atomic escaped data, +all documentation positions, layout tokens and ownership beyond input lifetime. +Input budgets bound token counts per node, indentation depth and escape expansion; +token generation checks them before any rendering/validation traversal. + +```console +cargo test -p wip-text-view +cargo clippy -p wip-text-view --all-targets -- -D warnings +RUSTDOCFLAGS='-D warnings' cargo doc -p wip-text-view --no-deps +``` diff --git a/vendor/wip-rs/wip-text-view/src/lib.rs b/vendor/wip-rs/wip-text-view/src/lib.rs new file mode 100644 index 000000000..ae8571d97 --- /dev/null +++ b/vendor/wip-rs/wip-text-view/src/lib.rs @@ -0,0 +1,221 @@ +//!

It produces and consumes framework-neutral `wip-http` messages but performs no network I/O and contains no UI types. - -```toml -[dependencies] -wip-client = "0.1.0" -``` - -Applications provide the HTTP adapter and presentation layer, send each prepared request exactly as owned by the runtime, then return the corresponding response for completion. - -## Interface identity and scope lifetime - -Interface acquisition and call APIs use `wip_protocol::InterfaceReference { scope, name }` directly. Within an endpoint/security-context session, the complete scoped pair is the cache key and the Object membership key: equal names in different scopes remain distinct. A scope is a canonical absolute Worldspace path and must be an ancestor of, or equal to, the call target path. Root scope (`/`) and self scope are valid; clients must not rewrite either into a different reference. - -`InterfaceObservation::scope_ref` is optional opaque metadata identifying the scope Object, not a third reference component, a path, or an Interface Descriptor validator. Its absence does not prevent acquisition or calls. Calls copy the exact observed reference, optional `scope_ref`, and optional Interface Descriptor validator into `InterfaceTarget`; the target Object validator is copied separately. The `CallContext` fixes those observations, the descriptor, and the operation declaration before dispatch. - -A descriptor without an Interface Descriptor validator is immutable only within the lifetime of its scope Object, not forever at that path. Descriptors with validators are also bound to that scope lifetime. When accepted observations establish that a known scope binding has changed or been lost, dependent cached interface state is invalidated and cannot authorize a new call until explicitly reacquired. A superseded interface response must not restore an observation from the old lifetime. A previously prepared call retains its original context rather than silently adopting a new scope identity or descriptor. - -Scope binding evidence is shared across Interface names at the same scope path: a new binding learned by fetching one name retires older descriptors for the other names too. Separately observed Object refs also provide lifetime evidence even when a descriptor's `scope_ref` was omitted. This corroboration is private bounded cache state, not an invented identity, and never fills in missing call metadata. Same-lifetime descriptor validation still applies; a detected ref change or loss retires the old lifetime instead. - -Object deletion, entry-edge removal, and local cache eviction are different events. A direct observe `NotFound` confirms unavailability at the requested scope path and removes cached interfaces scoped to that path; it does not guarantee identity-wide Object deletion or unavailability through every alias. Removing one entry edge likewise does not prove that the Object was deleted or invalidate every remaining alias. Cache eviction is local loss of retained knowledge, not evidence of Host deletion. Losing a known binding at an interface's scope path nevertheless ends safe reuse of descriptors dependent on that binding, even if the same Object remains reachable elsewhere. Optional `scope_ref` can provide identity evidence, but clients do not fabricate it when it is absent. - -Without Object `ref` or `scope_ref` identity evidence, a replacement at the same scope path can be indistinguishable from the previous Object. The runtime cannot detect every ref-less replacement from path and descriptor contents alone; absence of detectable change is not proof that the scope lifetime continued. - -## Explicit recovery and operation outcomes - -`ensure_observed` and `ensure_interface` avoid duplicate fresh or loading work; they do not automatically refresh retained stale or failed observations. Use the explicit object/children refresh APIs and `prepare_interface` to recover the observations required for a new call. An operation `InterfaceMismatch` invalidates both sides of the call's assumptions: it marks the target Object observation stale and invalidates the selected cached interface observation, so recovery requires reobserving membership and reacquiring the descriptor. Reobserving an Object and reacquiring its interface are retrievals, not a retry of an operation. - -The runtime never automatically retries an operation. Mark a call dispatched when handing it to the transport and report completion or transport failure with its original `RequestId`. A timeout, disconnect, or invalid response after dispatch can leave the outcome unknown: execution or commit cannot be ruled out. Refreshing stale state does not resolve that uncertainty and must not automatically resubmit the call; any new operation is an explicit application decision. - -See the [API documentation](https://docs.rs/wip-client) for session, acquisition, cache, and call APIs. - -Licensed under either of Apache-2.0 or MIT at your option. diff --git a/vendor/wip-rs/wip-client/src/lib.rs b/vendor/wip-rs/wip-client/src/lib.rs deleted file mode 100644 index d107bfce3..000000000 --- a/vendor/wip-rs/wip-client/src/lib.rs +++ /dev/null @@ -1,2325 +0,0 @@ -//!

All Host strings use standard JSON - escapes plus DEL/C1, Unicode line/paragraph separator and bidi-control escapes. - No normalization, case conversion, URL encoding or input mutation occurs. -- Documentation summaries are displayed in their prescribed positions, including - return documentation between `)` and `->`. Details are not displayed. Host text - is data, not renderer instructions or markup; quoting alone is not a prompt - injection defense.

Descriptor format -is checked after semantics: valid but unsupported formats return -`UnsupportedDescriptorFormat`, distinct from `InvalidDescriptor`. Supported format -is exactly `wip-interface/1`. Other validation errors preserve the Protocol's typed -`ValidationError` (also exposed as the error source). - -Bounded input limits are **1 MiB** of total string/opaque byte data, **16,384** -declarations/fields/parameters/cases/type expressions/references, **256** named type -declarations, and **64** TypeExpr nesting levels.

Host documentation is untrusted data, -//! not markup or instructions; quoting does not by itself prevent prompt injection. -//! -//! Each call checks resource limits, then Protocol shape/semantic validation. -//! Interface rendering additionally requires [`wip_protocol::INTERFACE_FORMAT_V1`]. -//! Limits reject the entire input, never produce partial text: at most 1 MiB of -//! input string/byte data, 16,384 declarations/fields/cases/type expressions or -//! references, 256 named type declarations (bounding validator graph recursion), -//! and 64 nested TypeExpr levels. These are implementation limits, not new -//! Protocol semantics. An Object without placement context can only be checked -//! for name/reference shape and duplicate references; the caller must validate -//! scope ancestry and observation consistency at its observation boundary. -//! -//! Signatures are display-only: no parser, round-trip, identity comparison, -//! cache key or call-target reconstruction is provided. The caller owns fetching, -//! freshness, authorization, selection and arrangement of multiple signatures. -//! -//! ``` -//! use wip_protocol::{Object, InterfaceReference, InterfaceDescriptor, INTERFACE_FORMAT_V1}; -//! use wip_text_view::{Interface, render_object, render_interface}; -//! let reference = InterfaceReference { scope: "/".into(), name: "example".into() }; -//! let object = Object { -//! name: "item".into(), description: None, interfaces: vec![reference.clone()], -//! r#ref: Some("not a path".into()), validator: Some(vec![1]), -//! }; -//! assert_eq!(render_object(&object)?, -//! "object {\n name: \"item\";\n interfaces: [\"/::example\"];\n}\n"); -//! let descriptor = InterfaceDescriptor { -//! format: INTERFACE_FORMAT_V1.into(), documentation: None, -//! types: vec![], operations: vec![], -//! }; -//! let interface = Interface { reference: &reference, descriptor: &descriptor }; -//! assert_eq!(render_interface(&interface)?, "interface \"/::example\" {\n}\n"); -//! # Ok::<(), wip_text_view::RenderError>(()) -//! ``` -//! -//! # Typed display tokens -//! -//! [`tokenize_object`] and [`tokenize_interface`] traverse the input structure -//! directly and return owned [`Token`] sequences, including all layout. Existing -//! render APIs use this same generation path followed by [`to_plain_text`]. The -//! input limits above also bound token allocation: tokens per node, indentation -//! depth and escape expansion are bounded; no partial signature is returned. -//! Token text is WIP-escaped, **not HTML-escaped** or escaped for other destinations. -//!
