…t_stdout allows
The CLI binary now initializes a `simple_logger` with no timestamps and no
level prefixes (so the user-facing UX is unchanged: `[edgezero] creating
project at ...` still prints exactly that), and all `println!` /
`eprintln!` sites are converted to `log::info!` / `log::error!` /
`log::warn!`.
Sites converted (24 total):
- `crates/edgezero-cli/src/main.rs`: top-level error reporters (`new`,
`build`, `deploy`, `serve`, `dev`) + status output for store-binding
warnings.
- `crates/edgezero-cli/src/generator.rs`: 9 status messages and 2 git
warnings now go through the logger.
- `crates/edgezero-cli/src/dev_server.rs`, `adapter.rs`: dev manifest /
command-failure reporting.
- `crates/edgezero-adapter-{axum,cloudflare,fastly,spin}/src/cli.rs`:
one build-artifact-path message each.
Allow-list: 47 → 45 entries (`print_stderr` + `print_stdout` removed).
Real renames + restructuring (no inline allow attrs):
- `non_ascii_literal` (3 sites): replaced the Japanese KV-key test literal
with `\u{...}` escapes (same runtime bytes, ASCII source) instead of
`#[expect]`-ing the lint. Replaced `→` arrow in a CLI test message with
`->`.
- `similar_names` (2 sites): renamed `decoded` → `output` in
`crates/edgezero-adapter-spin/src/decompress.rs` to break the
`decoded`/`decoder` prefix-share that the lint flags.
- `too_many_lines` (1 site): split `collect_adapter_data` in
`crates/edgezero-cli/src/generator.rs` into three helpers
(`blueprint_data_entries`, `render_manifest_section`,
`append_readme_entries`).
- `shadow_unrelated` (~14 sites): renamed every flagged inner binding
to be specific to its purpose:
- `serve_with_stores`: `let router = Router::new()...` →
`axum_router`; `let server = server.with_graceful_shutdown(...)` →
`graceful_server`; `let shutdown = ...` → `shutdown_signal`.
- `store_name_slug`: `Some(ch)` → `Some(lower_ch)` (was shadowing
outer `ch`).
- dev_server tests: `let url = ...` reused per-step → `write_url`,
`read_url`, `check_url`, `delete_url`, `save_url`, `load_url`;
`let resp = ...` → `write_response`/`read_response`/`save_resp`/
`load_resp`/`exists_before`/`exists_after`.
- `axum::key_value_store::get_bytes`: inner write-txn `table` →
`write_table`, `entry` → `fresh_entry`.
- `list_keys_page` cursor match: inner `Some(cursor)` → `Some(scan_from)`.
- `data_persists_across_reopens` test: second `let store = ...` →
`reopened`.
- `axum::response::into_axum_response` error path: `body` →
`error_body`, `response` → `error_response`. Test: `stream` →
`body_stream`.
- `fastly::key_value_store::list_keys_page`: inner `cursor` →
`next_cursor`.
- `fastly::proxy` test: collapsed two pairs of `body`/`collected` reuse
into named bindings (`plain_body`, `gzip_body`).
- `spin::decompress` test: `let result = ...` reused per-encoding →
`none_encoding`, `identity_encoding`.
- `core::body::from_stream_maps_errors` test: `stream` →
`source`/`chunks`.
- `core::key_value_store` tests: `let val = ...` reused → `after_first`/
`after_second`/`int_val`/`str_val`/`single_dot_err`/`double_dot_err`.
- `axum::cli::read_axum_project`: `Some(value)` → `Some(port_value)`
(was shadowing outer `value` from `toml::from_str`).
Allow-list: 45 → 41 entries.
…quest path
Real fixes (not just docs) for every production-code .expect() that could
fire under upstream contract change or misconfigured input:
- `IntoResponse::into_response` now returns `Result<Response, EdgeError>`
workspace-wide (breaking change). Cascades through `Responder`,
`EdgeError::into_response`, `RouterService::oneshot`, the handler future
in `core/handler.rs`, and the route-listing builder.
- `ProxyResponse::into_response` and `core::response::response_with_body`
now return `Result<Response, EdgeError>` and propagate `http::Builder`
failures via `map_err(EdgeError::internal)?` instead of `.expect()`.
- `core::body::Body::into_bytes_bounded` rewritten as a `match self {
Once | Stream }` so the unreachable `is_stream()`-guarded `.expect()`
pair is gone — the compiler proves exhaustiveness.
- `core/compression.rs` decoder slice access now propagates as
`io::Error::other(...)` instead of `.expect("AsyncRead contract")`,
so a malicious or buggy upstream stream fails the request rather than
crashing the worker.
- `axum/response.rs::into_axum_response` error path no longer uses
`Response::builder().expect(...)`; constructs the 500 response
directly via `Response::new` + `status_mut` + `headers_mut().insert`,
every step infallible by `http`-crate contract.
- `axum/proxy.rs` replaced `Default` (which panicked on TLS init) with
fallible `AxumProxyClient::try_new() -> Result<_, reqwest::Error>`.
Production caller in `request.rs::into_core_request` propagates as a
`String` error (matches the fn's existing return type).
- `fastly/logger.rs::init_logger` now returns
`Result<(), InitLoggerError>` (a typed enum wrapping the underlying
build error and `log::SetLoggerError`) instead of `.expect("non-empty
Fastly logger endpoint")`. `lib.rs::init_logger` re-exports the wider
return type.
- `cli/generator.rs::render_templates` propagates the previously-
`.expect("adapter context dir has a file name")` invariant as
`io::Error::other` since the surrounding fn already returns
`io::Result<()>`.
`axum/service.rs::call` (the tower `Service` impl) bridges the new
`Result<Response, EdgeError>` from `RouterService::oneshot` into a
`Response<AxumBody>` by mapping the error to a hard-coded 500 with a
plain-text body — `Service::call` returns `Result<Response, Infallible>`
so we cannot propagate further up the stack here.
`adapter-fastly` adds `thiserror` as a direct dependency for
`InitLoggerError`. All 557 workspace tests still pass.
Replaces the previous \`std::io::Result<()>\` / \`io::Error::other(format!(...))\`
shape across the \`edgezero new\` code path with two domain-specific error
types:
- \`crate::scaffold::ScaffoldError\` (variants \`Io { path, source }\` and
\`Render { name, message }\`) wraps every Handlebars failure and every
filesystem op inside template rendering with the offending path/template
name attached.
- \`crate::generator::GeneratorError\` (variants \`OutputDirExists\`,
\`AdapterDirMissingFileName\`, \`Io { path, source }\`, and
\`Scaffold(#[from] ScaffoldError)\`) replaces the workspace-construction
io::Error stringification.
\`generate_new\`, \`ProjectLayout::new\`, \`collect_adapter_data\`, and
\`render_templates\` all return \`Result<_, GeneratorError>\`.
\`adapter-cli\` and \`scaffold\` now depend on \`thiserror\` directly. All
557 workspace tests still pass.
The `IntoResponse::into_response` change in 1506738 turned the trait into `-> Result<Response, EdgeError>` workspace-wide. The demo app (`examples/app-demo/`) is excluded from the main `Cargo.toml` workspace, so it didn't get rebuilt by the workspace clippy/test gate and silently broke. This propagates the same fix to the demo: - Every `block_on(handler(ctx)).expect("handler ok").into_response()` in `crates/app-demo-core/src/handlers.rs` test code now appends `.expect("response")` to unwrap the response result. - Every `into_body().into_bytes()` test path now appends `.expect("buffered")` since `Body::into_bytes()` returns `Option<Bytes>` (changed in the defensive-coding pass). `cd examples/app-demo && cargo test --workspace --all-targets` passes all 21 demo handler tests; `cargo clippy --workspace -- -D warnings` also clean.
Inherit pedantic+restriction lints in the demo workspace and each demo crate. Fix the lints that flagged real issues in the demo handlers (`as _` trait imports, inlined format args, fast-path `to_string`, renamed shadowed bindings, separated literal suffix). The demo's allow-list is intentionally narrower than the library's — only entries the demo actually trips. New allows can be added lazily as future failures surface.
Add a clippy.toml mirroring the parent (allow expect/unwrap/panic/ indexing-slicing in tests). Then refactor away the workspace allows that were genuine wins: - shadow_reuse: rename `chunk` and `cursor` shadows - absolute_paths: import std::env, std::time::Duration, std::process, and use already-imported Arc instead of std::sync::Arc - default_numeric_fallback: add type suffixes (1_u64, 0_i32..3_i32, 1_i64) - pattern_type_mismatch: implicitly fixed by str_to_owned changes - missing_trait_methods: implement KvStore::exists on the test MockKv - expect_used in production code: stream() now propagates the response builder error via EdgeError::internal The remaining allow-list keeps only entries the demo actually trips that match main's philosophical stance — std (not core/alloc) for binaries, idiomatic `?` over match, terse closure idents, and the single exhaustive_structs site that comes from the `app!` macro.
- str_to_string (21 sites): `.to_string()` → `.to_owned()` on `&str` - arithmetic_side_effects: counter `n + 1` → `n.wrapping_add(1)` - min_ident_chars + pattern_type_mismatch: rename closure destructures `|(k, v)|` → `|&(name, value)|`/`|&(key, value)|` - pub_with_shorthand + field_scoped_visibility_modifiers: drop `pub(crate)` shorthand on the demo's DTOs and handlers — the `mod handlers;` declaration is already private, so plain `pub` is crate-private at the boundary - print_stderr: axum main returns `anyhow::Result<()>` and lets the Termination impl render errors; fastly/cloudflare host stubs keep `eprintln!` behind a localized `#[expect]` with reason since they only run on the wrong target Workspace allow-list now keeps only the entries that match main's philosophical stance (idiomatic `?`, `pub` shorthand handled per-call site, etc.) plus the single `exhaustive_structs` site from the `app!` macro.
Drop the `arbitrary_source_item_ordering` allow in favor of the canonical clippy-restriction layout: - Top of `handlers.rs`: consts (alphabetical), then structs (alphabetical: ConfigParams, EchoBody, EchoParams, NoteIdPath, ProxyPath), then handler fns - Test mod: uses, then structs (alphabetical), then impls grouped with their self-types, then helper + test fns interleaved in alphabetical order - `impl KvStore for MockKv` methods alphabetical (delete, exists, get_bytes, list_keys_page, put_bytes, put_bytes_with_ttl) - Hoisted the late `use edgezero_core::secret_store::...` up to the test mod's use block No behavior changes — pure reordering. Demo workspace allow-list drops to 8 entries.
The `edgezero new` generator now scaffolds the same lint policy EdgeZero itself uses: - Root `Cargo.toml` carries `[workspace.lints.clippy]` (pedantic warn + restriction deny) with the same demo-tested allow-list - Root `clippy.toml` exempts tests from `unwrap`/`expect`/`panic`/ indexing-slicing restriction lints - Each generated crate's Cargo.toml inherits via `[lints] workspace = true` Generated projects are clippy-clean against the strict gate out of the box.
Both adapters were calling `from_core_response` directly on the router's return value, but `oneshot` now yields `Result<Response, EdgeError>` since the response builder errors propagate through the router. Extract the response with `?` first so the wasm32 builds (`--target wasm32-unknown-unknown` for cloudflare, `--target wasm32-wasip1` for spin) compile again.
… per-site Real fixes (allows now justified by audit, not laziness): - build.rs returns `Result<(), Box<dyn Error>>` instead of expect-panicking - adapter registry / blueprint registry recover from poisoned RwLocks via `unwrap_or_else(PoisonError::into_inner)` rather than expect-panicking - ManifestLoader gains `try_load_from_str` returning `io::Result`; adapter `run_app` paths propagate via `?`. The non-fallible `load_from_str` keeps its panic-on-bad-input contract for compile-time-embedded manifests, with a documented per-fn `#[expect(clippy::panic, reason = ...)]` - `expand_app` macro emits `compile_error!()` instead of panicking on bad `edgezero.toml` (rustc surfaces a clean build error) - `parse_handler_path` keeps a panic with a clear reason — proc-macro expansion errors *are* build failures - `partial_pub_fields` on `Manifest`: privatized `root` and `logging_resolved`, kept the deserialized fields `pub` for the public API. Localized `#[expect]` documents the deliberate split - `must_use_candidate` fixed on cli_support helpers via `#[must_use]` - `missing_inline` fixed on adapter/scaffold registry functions - `pub_use`, `format_push_string`, `arithmetic_side_effects`, `default_numeric_fallback`, `pattern_type_mismatch`, `min_ident_chars`, `str_to_string`, `absolute_paths`, `module_name_repetitions`, `shadow_reuse`: all kept as workspace allows but with concise rationales replacing the prior verbose audit notes Each remaining workspace allow now has a one-line reason. The list is shorter than before but explicitly accepts the lints whose "fix" would universally make the code worse (match-ergonomics destructures, std-only binary entrypoints, idiomatic `?`/return).
…space-wide 54 sites across 23 files. Fixed places where my bulk replace had wrongly converted Display::to_string() calls (anyhow::Error, io::Error, i32 etc.) back to .to_string(). The lint allow is dropped from the workspace.
23 sites across extractor.rs, key_value_store.rs, middleware.rs, proxy.rs, adapter-axum dev_server/key_value_store, adapter-spin decompress. Validator length(min=N) gets _u64; range(min=N, max=N) gets matching type suffix; loop-bound and assertion literals get explicit i32.
Core crate: replaced 60+ `std::collections::HashMap`, `std::sync::Arc`, `std::ops::Deref/DerefMut`, `crate::error::EdgeError`, `futures::executor::block_on`, `std::task::*`, `std::string::String::*` absolute paths with explicit `use` statements. Axum proxy.rs: imported the various `axum::http::*` and `axum::routing::*` types used in test functions. The lint stays allowed at the workspace level for adapter test modules where one-shot uses of framework types like `axum::http::HeaderMap` and `fastly::kv_store::KVStore` are clearer inline.
Real fixes (workspace allows dropped, code refactored): - AdapterAction marked #[non_exhaustive] with wildcard arms in adapter cli match sites — drops a workspace exhaustive_enums concession - Adapter crate exposes `pub mod registry` instead of pub-using items at the crate root — drops the workspace pub_use concession - expand_action_impl made private (no longer pub(crate)) — drops the workspace pub_with_shorthand concession on this site - ManifestLoader, Manifest, ManifestApp/HttpTrigger/Environment/Binding/ ResolvedEnvironment*, ManifestAdapterBuild/Commands, ManifestConfigStoreConfig, ManifestLoggingConfig, ResolvedLoggingConfig, ManifestKvConfig, ManifestSecretsConfig, HttpMethod, LogLevel — all reordered to match canonical clippy item ordering (consts first, then structs, impls, fns; alphabetical within each group) - Manifest impl methods sorted alphabetically; Manifest fields sorted - match-ergonomics destructures rewritten as let-else for clarity - HttpMethod gained Copy; LogLevel/HttpMethod take `self` (drops trivially_copy_pass_by_ref) - partial_pub_fields fixed via consistent pub on Stores in fastly request - needless_pass_by_value: run_app_with_config / run_app_with_logging take `&FastlyLogging`; map_edge_error / map_lookup_error take by ref; build_fastly_request takes `&HeaderMap`; generate_new takes `&NewArgs` - expect_used localized on register_templates with rationale - ManifestLoader::load_from_str / parse_handler_path keep panic-on-bad- build-input contract documented per-fn - Router: route-listing duplicate-path panic + add_route panic both documented per-fn (build-time programmer error) - spin contract test uses #[allow] for expect/tests-outside per file - separate manifest_definitions.rs in macros crate (drops mod-after-use) Workspace allows that survived (most match audited rationales): implicit_return, question_mark_used, single_call_fn, separated_literal_suffix, pub_with_shorthand (rustfmt-enforced), pub_use, min_ident_chars, single_char_lifetime_names, shadow_reuse, module_name_repetitions, format_push_string, pattern_type_mismatch, arithmetic_side_effects, float_arithmetic, as_conversions, exhaustive_structs, exhaustive_enums, missing_trait_methods, absolute_paths, std_instead_of_alloc/core, missing_inline_in_public_items, tests_outside_test_module, arbitrary_source_item_ordering (core-crate files outside manifest.rs). Tests pass, strict clippy clean across workspace + demo.
Override KvStore::exists in 4 production impls (axum/fastly/cloudflare + NoopKvStore) and the in-test MockStore. Override configure/name/ config_store/build_app in the two Hooks test impls. Update the #[app] macro to emit configure, build_app, and a None-returning config_store when [stores.config] is absent so generated user apps still pass clippy. Add explicit clone_from to RouteEntry's Clone impl.
Delete config_store, key_value_store, and secret_store crate-root
re-exports — items remain reachable via the `pub mod` paths. Update the
two short-path callers (axum service.rs / secret_store.rs) to use full
module paths. Keep `pub use edgezero_macros::{action, app}` and the
`http` facade re-exports — these are the only surviving sites and the
lint is module-scoped so it cannot be silenced per-item. Workspace
allow rationale updated to point to those two patterns.
The previous comment framed `push_str(&format!(...))` as a stylistic preference. It is actually the only call-site form that satisfies the full restriction-deny gate: `write!(s, ...)` returns a `Result` which trips `let_underscore_must_use` under `let _ =`, `unwrap_used` under `.unwrap()`, and `expect_used` under `.expect()`.
Switch generator.rs from `push_str(&format!(...))` to `writeln!(...)?` which writes directly into the buffer (no temp String allocation) and propagates `std::fmt::Error` rather than silencing it. Add `GeneratorError::Format(#[from] std::fmt::Error)` and bubble the result through `render_manifest_section` and `append_readme_entries`. Drop the workspace allow.
Rename 'a → 'mw on Next, 'a → 'route on RouteMatch, 'a → 'manifest on manifest_command, and 'a → 'blueprint on AdapterContext. Drop the workspace allow.
Eliminate let-rebinding shadows across core, fastly, axum, and cli
crates. The recurring patterns:
- `while let Some(chunk) = stream.next().await { let chunk = chunk?; }`
→ rename outer to `result`, keep inner `chunk`
- `if let Some(cursor) = cursor.filter(...)` → rename outer/inner to
distinct names
- `let path = path.into()` (Into-paramter idiom) → rename to
destination-specific name
- closure params shadowing outer captures → rename closure param
All renames preserve semantics; tests + workspace clippy + wasm
target checks all pass.
Split `#[cfg(all(test, feature = "..."))]` on test modules into two separate cfg attributes (`#[cfg(test)] #[cfg(feature = "...")]`) which the lint recognizes correctly. Affects edgezero-adapter-fastly lib.rs and edgezero-cli main.rs.
Convert the http builder re-exports to `pub type` aliases (real fix — no `pub use` required) and wrap the `header` re-export in a child module with a scoped `#![expect]`. Add file-level `#![expect(clippy::pub_use)]` to each adapter lib.rs (axum, fastly, spin, cloudflare) and to edgezero-core/lib.rs for the proc-macro re-export. Cloudflare uses `cfg_attr(target_arch = "wasm32", expect)` because its re-exports are wasm-gated and would leave the expect unfulfilled on the host build.
For each adapter (axum/fastly/spin/cloudflare): make the previously
private internal modules `pub mod` and drop every `pub use` re-export.
Callers now reach types via the full path, which is what the lint
suggests as the proper fix. Update internal cross-module refs and
external callers (edgezero-cli, demo crates, axum/spin scaffold
templates, fastly/spin/cloudflare contract tests).
Remaining `pub_use` expects:
- `edgezero-core/src/lib.rs` — single-line proc-macro re-export
(`pub use edgezero_macros::{action, app}`); the canonical proc-macro
distribution pattern requires this and the lint is module-scoped, so
a tightly-scoped file-level expect is the only available form
- `edgezero-core/src/http.rs::header` — wrapped in a child module with
the expect scoped to that one line; required by the CLAUDE.md HTTP
facade rule
The two `#[allow(deprecated)]` annotations on `AppExt::dispatch` implementations (cloudflare/fastly) were unnecessary — implementing a deprecated trait method does not trigger the `deprecated` lint, only calling the deprecated declaration does. Drop them. Also fix the fastly contract integration test (wasm32-only) which was still importing names from the previous crate-root re-exports — switch to the new `request::`/`response::`/`context::` module paths.
Per-package `.cargo/config.toml` is only honored when cwd is inside the package directory, so `cargo test -p edgezero-adapter-fastly --target wasm32-wasip1 --test contract` from the workspace root fails to resolve the Viceroy runner. Mirror the runner at the workspace level. Cargo invokes test runners with cwd set to the package manifest directory, so `../../examples/...` resolves correctly for any adapter package targeting wasm32-wasip1.
Three previously-duplicated wasm test jobs (cloudflare, fastly, and a new spin entry) collapse into one `adapter-wasm-tests` matrix that varies on adapter, target, and runner. Spin uses Wasmtime; fastly keeps Viceroy; cloudflare keeps wasm-bindgen-test-runner. Per-adapter toolchain installs are gated with `if: matrix.adapter == ...` so each job only pulls what it needs. Also fix a pre-existing compile error in `crates/edgezero-adapter-spin/ tests/contract.rs:171` (`name == "x-edgezero-res"` needed a deref) — silently broken because there was no CI job exercising it.
Remove the `extra_check` matrix flag and gating `if:` — every adapter in the wasm matrix now runs the same test+check pair, and the duplicate "Check Spin wasm32 compilation" step in the top-level `test` job (now redundant with the matrix's spin cell) goes away. axum is the host-target adapter — its 102 tests already run as part of `cargo test --workspace --all-targets` in the `test` job. It has no `--test contract` integration target, so adding it to the wasm matrix would either need a special-case command or duplicate the workspace-test work. Keeping it in the `test` job is the simpler call.
The cargo cache restores `~/.cargo/bin/{viceroy,wasm-bindgen-test-runner}`
from prior runs; a bare `cargo install` then fails with `binary already
exists in destination`. Match the same `command -v` guard the spin step
already uses, and for wasm-bindgen also re-check the version (the cache
key is per-Cargo.lock so a wasm-bindgen bump in lockfile needs a refresh).

- Define config-store / kv-store / secret-store capability semantics (bare enum variants had no doc comment, unlike the six outbound caps). - Add explicit transport-error mapping bullets to the Cloudflare (§4.2) and Spin (§4.4) adapters, matching Axum/Fastly (DNS/TLS/connect -> bad_gateway). - Collapse the now-obsolete dual-baseline enforcement-gate hedging: PR #269 has merged to main, so the #269 sibling-gate topology is the active shape and the pre-#269 wording is marked historical.
- §4.3: document Fastly send_all cancellation/drop semantics (no async cancellation; every PendingRequest is harvested; sibling deadline never aborts other slots). - §3.3.1 / §3.1.3: spell out Deadline::after overflow fallback and into_response()'s only Err (adapter-invariant internal) condition. - §5.4: add test rows for Json/ValidatedJson cap migration, the *Within explicit-cap extractors, the per-adapter capability() matrix, and back-compat manifest parse. - §5.5: state where Tier 2 runs per adapter (host gate for Axum; per-adapter wasm-target matrix for the three WASM adapters). - §7: add dispositions for adapter request.rs, the Tier 3 MockServer, the run_* gate-site files + ensure_capabilities home, and CLAUDE.md/workflow wasip2 refresh; note sha2 is already a workspace dep. - Collapse the now-obsolete dual-baseline (#269 pre/post) framing in §3.5.2, §5.5, and §6 to the post-#269 shape, keeping the pre-#269 note as history.
- into_response(): drop the unreachable 'body handle surrendered by a prior terminal call' Err example — all terminal methods take self by move, so double-consumption is a compile error; reword as infallible-in-safe-use with a reserved internal path. - §5.4 capability() matrix row: include the omitted BoundedCooperative variant (CapabilitySupport has four variants: Native / BoundedCooperative / BestEffort / Unsupported).
…er (WIP) Amends the spec from three source-verified investigations (spin-sdk 6/wasip3, worker 0.8.3/workerd, Spin host-sync lifecycle) plus review findings: - Spin: replace the unimplementable WASI-0.2 upload loop (wasi:io is deleted in WASI 0.3) with a hand-built wasi:http request; the SDK's high-level send spawns an uncancellable body pump. Lazy response passthrough = BestEffort (EdgeZero's own FullBody alias, not a platform limit). - Cloudflare: set-cookie IS preservable (compat_date already enables it); the collapse is HeaderMap::insert. Second collapse bug on the client-facing path (Headers::set) and a to_str().unwrap() panic hazard. Comma-joining of repeated non-set-cookie headers is the real, narrow loss. - Spin host sync: provision writes, build/serve/deploy validate at adapter.rs::execute (a hook in SpinCliAdapter::execute would be dead code). - Fastly SendErrorCause -> 504/502; RequestContext::new preserved; test seams behind test-utils (not cfg(test)); tiers redefined by owning crate. Known-open: a follow-up review found compile-level errors in the normative pseudocode (pub(crate) validator across crates, builder/getter name collisions, Spin pump result handling, StoredError reconstruction, Hooks defaults vs denied missing_trait_methods). Tracked in the decisions register; NOT ready for task-level planning.
…cs/outbound-http-spec
…ted)
Built a 2-crate compile-check skeleton (core + separate adapter crate) and let
the compiler/clippy adjudicate the review's compile-class findings:
- validate_for_dispatch: pub (pub(crate) is unreachable from adapter crates) [E0603]
- deadline accessors: single budget_inputs() struct accessor (getter names
collided with the public builder setters -> E0592 duplicate definitions)
- Spin pump: unwrap Result<Bytes,EdgeError>, keep+prioritize pump result
(join!(...).1 silently discarded source errors and cap overflow)
- StoredError: variant-specific snapshot enum ({kind,message} doubled Internal's
prefix and couldn't hold ConfigOutOfDate/MethodNotAllowed/NotFound payloads)
- Capability schema: inline in manifest.rs + derive Serialize (reconciled active
section with §7; separate capability.rs won't compile in the macro include)
- Baked manifest: app! must emit BOTH Hooks methods (clippy::missing_trait_methods
is denied -> proven error); manifest() uses a per-impl function-local OnceLock
calling a PUBLIC Manifest::from_baked_json (reparse must call pub(crate) finalize,
unreachable from the downstream generated impl)
- Spin host default: Option<Vec<String>> (absent=None https-only vs explicit
["*"]=http+https; bare Vec can't carry the distinction -- serde test passes)
- Fastly cache: MUST be session-scoped thread_local!, not a per-request client
field (client is constructed per inbound request; names are session-global ->
request #2 fails closed on NameInUse)
- provision: corrected -- receives NO host data; needs manifest re-read or a
signature change (my earlier 'no trait change' was wrong)
- config validate: run_config_validate_typed is a separate public entry generated
CLIs call directly; gate must be a shared inner op behind both entries
- Fastly test seam: recording BackendBuilder, not a cache inspector (Backend is
opaque -- getters don't round-trip SSL/SNI/cert/override_host)
Skeleton at scratchpad/skel compiles green in corrected form. Still open: policy
calls (loopback-vs-no-network, command-class gating, compression, migration
completeness incl PROXY_HEADER + error-JSON status field).
Skeleton (scratchpad/skel, compiles green) confirmed the CLI-gate wiring shape:
a gate on only one of run_config_validate / run_config_validate_typed leaves the
typed path silently ungated -> must be a shared inner gated op both entries call.
Policy decisions (all user-locked):
- Command-class gating: gate runtime-producing/mutating (build/serve/deploy/
provision/config push) + validation (config validate); EXEMPT read-only
diagnostic (config diff, auth status) and credential (auth login/logout). This
REVERSES the earlier 'gate config diff' lock. Gate count 6 -> 5; execute(..)
branches to skip auth. Swept §3.5.3 table, §5.4 enumerations (+ exemption
regression-guard row), §6/§7 counts, §1 header.
- Loopback tests: amend CLAUDE.md so 'network' = public internet; a loopback
mock origin is permitted (in-process fake rejected -- can't prove real socket
concurrency).
- Compression: decode single gzip/br; identity/unknown/stacked/repeated ->
passthrough untouched (bytes + content-encoding intact), never a hard fail.
Case-insensitive token match. Normative table added to §3.4.1.
- PROXY_HEADER (x-edgezero-proxy): PRESERVED through the rename.
Migration honesty (finding 13): replaced the false 'no public capability lost'
claim with an enumerated removal table -- ProxyHandle::client(), body_mut(),
extensions()/extensions_mut(), request_mut() are DROPPED (breaking); PROXY_HEADER
preserved. EdgeError JSON shape corrected to the REAL converter's
{status, kind, message, field_path?}, not {kind, message}.
…e appendices) Independent source-grounded verification review: compile-class CLEAN (no blockers), current-tree claims ALL accurate. Two active defects were my own incomplete command-class-gating sweep from the prior round, plus three stale appendix entries: - §7 CLI gate enumerations (both) still gated the EXEMPT config diff and said execute(..) covers auth. Corrected: execute gates build/serve/deploy only (branches to skip Auth*); four siblings run_provision/run_config_push_typed/ run_config_validate/run_demo; run_config_diff_typed is NOT a gate site. - §5.4 row asserted the execute gate fires on auth -> corrected to build/serve/ deploy only, + asserts config diff / auth do NOT hard-fail. - Appendix entries: added [SUPERSEDED] markers (not rewriting frozen history, matching the spec's existing 'superseded by AY' convention) to: lazy=Native- on-three-WASM-adapters (only CF Native now), the WASI-0.2 subscribe/check_write protocol (doesn't exist in SDK 6), and the #[cfg(test)] seam (must be test-utils). Also compile-verified the Fastly session-cache thread_local! pattern in the skeleton (request #2 reuses across per-request clients; mismatch fails closed). Gate count now consistently FIVE across §3.5.3, §5.4, §6, §7; auth + config diff exempt everywhere in the authoritative body.
…tives)
First executable TDD slice of the outbound-http implementation. Scoped to the two
purely-additive, skeleton-verified core primitives that keep cargo test --workspace
green at every step:
- EdgeError::BadGateway (502) / GatewayTimeout (504): variants, constructors, all
five exhaustive-match updates (kind_str/message/status/inner/into_response
field_path), + tests for status/kind/message and the {error:{status,kind,message}}
JSON shape (no field_path). Test code verified against the real error.rs APIs
(sync into_bytes(), nested error-wrapping).
- time.rs: Deadline (after with DEADLINE_FAR_FUTURE clamp + saturating checked_add,
at_instant/instant/remaining/is_expired), DispatchBudget struct, and the three
budget constants with exact verbatim values.
dispatch_budget() itself is explicitly deferred to Phase 1b (needs OutboundRequest +
the budget_inputs() accessor), which is the breaking proxy->outbound rename slice.
PLAN (all findings verified against the real tree before fixing): - Task 1 would NOT have compiled: enumerated only 5 exhaustive EdgeError matches, but there are EIGHT -- the 3 test-module matches (error.rs 281/335/369) have explicit panic-arms listing every other variant with NO '_' wildcard, so adding two variants breaks them. #[non_exhaustive] does not relax exhaustiveness inside the defining crate. Listed all 8 + added a compiler-driven catch step (E0004). - is_expired() was WRONG at exact equality: checked_duration_since returns Some(ZERO) at t==deadline, so it reported not-expired, contradicting the spec's 'deadline <= now => expired'. Now compares instants directly; remaining() returns None at equality. Added an equality test. - 'cargo test -p X a b' is invalid (verified: unexpected argument 'b'). Single filter. - GatewayTimeout's JSON contract was untested -> both variants table-driven, and the existing kind_strings_per_variant matrix (error.rs:502) gains rows (with the suffixed 502_u16/504_u16 literals the macro actually uses). - Flaky timing tests replaced with instant-bounded ones (no now()-1s underflow, no 50-60s tolerance); the Duration::MAX test now actually proves the 7-day clamp. - DispatchBudget moved to Phase 1b to ship with its producer (spec treats §3.3.2 carrier+producer as one contract). - fmt added to Task 1; Task 3 now runs all five CI gates incl. fmt --check and the wasm32-wasip2 target. - Phase 1b noted as multiple slices, not one atomic step. SPEC (stale pseudocode/footnotes the prose sweeps missed): - Fastly cache ownership normalized to ONE owner: session-scoped thread_local! + RefCell (single-threaded guest, no Mutex). Removed the contradictory per-client 'Mutex<HashMap> on FastlyOutboundClient, one per request context' claims, which fail on the 2nd inbound request (names are session-global, client is per-request). Test seam targets the thread-local, not a client field. - Footnote 2 claimed between_bytes_timeout bounds streamed-upload inter-chunk gaps; it is receive-side only and bounds nothing on the guest->origin write path. Now agrees with §4.3 and §8 risk 7: BOTH source-pull and host-write are BestEffort. - CLI gate pseudocode rewritten: execute(..) branches to skip Auth*, gates the TYPED push path (bundled run_config_push is an erroring stub), validate is adapter-less and loops configured adapters behind ONE shared gated_validate that both the bundled and typed entries call, demo reads the baked Hooks::manifest(), and run_config_diff_typed is explicitly NOT a gate site. - Spin sample applied '?' to Option<Duration> in a Result fn -> explicit let-else to gateway_timeout.
…r stages
Verified every finding against the tree/compiler before fixing.
PROVEN BUGS (skeleton-adjudicated):
- Trait-default static is NOT per-impl. Proof test: two Hooks impls relying on a
caching default BOTH returned the first impl's value (AppA=1, AppB=1) -- items
in generic fns are not monomorphized, so ONE static is shared by all
implementors. As specced, app A's baked manifest would serve app B's capability
checks. Fix: default manifest() returns None; the OnceLock lives in each
macro-generated impl (distinct static per impl). Test kept as a regression guard.
- The repo DENIES clippy::restriction wholesale (root Cargo.toml) and does NOT
allow-list missing_inline_in_public_items / min_ident_chars /
arithmetic_side_effects / expect_used / as_conversions. My Phase 1a Deadline
code and the spec's pseudocode both violated it:
* plan: added #[inline] to every public fn, d -> duration, replaced
with checked_duration_since + explicit zero filter via pure remaining_at(now)/
is_expired_at(now) helpers (which also make the tests exact/deterministic --
no tolerance windows, no now()-1s underflow; the clamp test now bounds
d.instant() to prove the 7-day clamp).
* clippy.toml allows expect/unwrap/panic IN TESTS but NOT arithmetic_side_effects
-- documented, hence checked_add(..).expect(..) in test code.
* spec: dispatch_budget .expect(..) -> explicit invariant EdgeError::internal;
fastly_timeout_ms casts + unchecked arith -> as_millis + saturating +
u64::try_from (compile-verified AND behaviour-tested: sub-ms->1, 1.5ms->2,
Duration::MAX clamps without panic).
FASTLY CONTRADICTIONS:
- Step 6 listed DNS/TLS as Backend::builder().finish() errors; they only arrive from
send. Split the two stages (BackendCreationError vs SendErrorCause), which also
makes the §5.4 rows writable (a fake builder cannot produce a DNS branch).
- Decided the ambiguous cause: DnsTimeout -> 504 (classify by 'did a timer fire?',
not by subsystem); DNS resolution failure (NXDOMAIN) -> 502.
- Canonical-accessor test row pointed at map inspection; Backend is opaque -> now
targets the recording BackendBuilder (map inspection reserved for identity/reuse).
- Purged mutex-era reasoning from the thread_local algorithm ('drop the lock' ->
'release the borrow'); removed the impossible 'prior session / another deployment'
NameInUse cause (names are session-scoped and may overlap across sessions) and
replaced it with the three real causes.
- Upload summary still claimed a BoundedCooperative write-side bound and that only
source-yield was the 'worst phase' -- both phases are unbounded BestEffort.
- [SUPERSEDED] markers on the two appendix Mutex-era entries.
STALE FOLLOW-UPS (verified already done -- would have scheduled redundant work):
- Risk 10 (Spin wasip2 refresh) CLOSED: CLAUDE.md already quotes wasip2 for gate 5
and lists Spin as wasm32-wasip2; surviving wasip1 refs are Fastly's (correct).
- §1 header no longer claims the CLI gates are unreconciled -- §3.5.3 reconciles them.
- §7 CLAUDE.md entry now carries the real deliverable: amend the unqualified
no-network rule to permit a loopback mock origin.
…rror policy Reviewer compiled the Phase 1a code under the repo's lint policy and found duration_suboptimal_units. I reproduced the repo's EXACT lint table in an isolated crate and found MORE than reported -- then iterated to green. PHASE 1a PLAN (now verified GREEN under the repo's real gate): - duration_suboptimal_units (pedantic; CI runs -D warnings so it FAILS the build): from_secs(7*24*60*60) -> from_hours(168); from_secs(60) -> from_mins(1). - arbitrary_source_item_ordering (denied restriction) -- NOT in the review, found by compiling: items must be ALPHABETICAL, and it policies ENUM VARIANTS too (proven: appending BadGateway after Validation errors). The plan said "add after Validation", which would have failed on first build. Corrected: BadGateway before BadRequest, GatewayTimeout between ConfigOutOfDate and Internal; constructors likewise. Deadline's methods reordered alphabetically. - Confirmed std_instead_of_core/std_instead_of_alloc ARE allow-listed, so `use std::time::Duration` is fine (checked the full allow-list rather than guessing). - Fixed the two "compares instants directly" descriptions -- impl uses checked_duration_since(..).filter(..). SPEC (High): - ManifestCapabilities/ManifestOutboundCapability derived only Deserialize while Manifest derives Serialize -> would break Manifest's derive and the macro crate. Both now derive Serialize. - SECURITY: hosts was Vec<String> defaulting to ["*"], but the renderer defines "*" as http+https while an ABSENT field must stay https-only. Every existing manifest that never declared hosts would silently gain cleartext outbound on next build. Now Option<Vec<String>>: None -> ["https://*:*"]; Some(["*"]) -> http+https (opt-in); Some([]) -> rejected. Validator signature updated to the inner slice. - Fastly error policy: replaced the two catch-alls with an EXHAUSTIVE per-variant table built from the real fastly-0.12.1 enums. Key correction: ConnectTimeoutTooLarge /FirstByteTimeoutTooLarge/BetweenBytesTimeoutTooLarge/NameTooLong/EncodingError and HttpRequestUriInvalid/InternalError mean EDGEZERO violated its own clamp/name/URI invariants -> `internal` (500), NOT bad_gateway. Mapping them to 502 disguises an adapter bug as an upstream failure. Widened the §5.4 "internal only on three paths" assertion to five, with a regression guard against the 502 mapping returning.
…t sweep)
Addresses ALL remaining feedback. Verified each against the real SDK/tree.
SECURITY -- baked-manifest gate failed OPEN:
- parse-failure and "no manifest" both collapsed to None, and ensure_capabilities
treats None as permission to proceed => a MALFORMED baked contract silently
disabled required-capability enforcement (the gate reports success exactly when
it can no longer verify anything). Replaced Option with a three-state
BakedManifest { Absent, Present(&'static Manifest), Malformed(&'static str) }:
Absent proceeds (no contract), Malformed HARD-FAILS with an actionable message.
- Macro output now uses fully-qualified paths (::edgezero_core::manifest::Manifest,
::std::sync::OnceLock) -- it expands in a downstream crate that may not have them
in scope.
FASTLY -- test seam was impossible as specced (verified against fastly-0.12.1):
- SendError has private fields + no public ctor; SendErrorCause is #[non_exhaustive].
NEITHER is constructible in a test, so "one test per SendErrorCause" was unwritable.
Also retracted my own earlier instruction to "match SendErrorCause exhaustively so a
future variant is a compile error" -- #[non_exhaustive] makes that impossible; a `_`
arm is mandatory. BackendCreationError is the opposite (not non_exhaustive =>
constructible AND exhaustively matchable). Documented the asymmetry and split
classification: a pure classify(SendFailure) over a locally-defined constructible
enum (unit-testable), plus a thin cause_to_failure boundary map covered by Tier 3.
- Purged the last mutex-era reasoning: "prior session" NameInUse cause (names are
session-scoped; a fresh session starts clean), "outer lock held continuously",
"no other thread", finer-grained locking. Now stated in single-threaded
session-map-borrow terms. [SUPERSEDED] marker added to the last appendix entry.
CLI:
- Manifest::configured_adapter_names() does not exist -> iterate
manifest.adapters.keys() (BTreeMap<String, ManifestAdapter>, manifest.rs:95;
ordered => deterministic failure reporting).
- The three config commands are NOT symmetric; replaced the over-general "same
applies to push/diff" with a per-command table: push = gate the TYPED path only
(bundled is an erroring stub, nothing to gate); validate = shared inner op both
entries call (the only one needing it); diff = never gated.
LINT SWEEP (spec pseudocode, same gate as Phase 1a):
- sent += chunk.len() -> saturating_add (arithmetic_side_effects).
- production cert_host().unwrap() -> explicit if-let (unwrap_used).
- dispatch_budget: added #[inline] + the lint contract; |dur| -> |duration|
(min_ident_chars), including the closure body.
PHASE 1a PLAN:
- The new variants must also join the retry_after_* and field_path_* matrices
(502/504 carry neither), not just kind_strings_per_variant -- three matrices.
…+ strip meta-refs from code comments
Verified each finding against the tree/compiler before fixing.
HIGH (self-inflicted lifetime bug): ensure_capabilities took BakedManifest, whose
Present holds &'static Manifest, but the four file-backed gate sites pass LOCAL
&Manifest borrows (not 'static) -> cannot compile. Introduced a lifetime-bearing
ManifestContract<'a> { None, Malformed(&'static str), Present(&'a Manifest) };
BakedManifest converts in via as_contract(); file-backed callers build it from
Option via from_opt. Fail-closed on Malformed preserved.
HIGH (StoredError): the "total" capture omitted NotImplemented + ServiceUnavailable
(EdgeError has 10 variants); MethodNotAllowed stored String not Method (forcing a
fallible reconstruction); the cancellation example used the REJECTED flat
{kind,message} shape; and three call sites used clone_as_edge_error() while the
method is to_edge_error(). All fixed.
HIGH (Fastly error classification, mutually-exclusive rules): creation step-6 prose
+ the §5.4 stage-1 row said "every non-NameInUse -> 502", contradicting the
per-variant table (clamp/name/encoding -> internal 500). And a "internal is never
correct during send" sentence contradicted SendFailure::LocalInvariant. The
per-variant tables are now authoritative everywhere; the blanket-502 prose is gone.
HIGH (Fastly cache unbounded): backend identity used EXACT ceiled budget_ms, which
drifts by the ms across requests (97/98/99 for a nominal 100ms deadline) while the
thread_local map is session-wide -> one leaked backend per distinct ms, unbounded.
Now identity uses budget_bucket_ms (ceil to a 1-2-5 grid); host timers armed with
the bucket (>= real budget, a looser backstop) while the exact deadline stays
enforced by the cooperative is_expired() check. Bounds distinct backends per host to
~a few dozen, independent of request count. Added a bound-assertion §5.4 row.
HIGH (Spin provisioning wrong-file): recommended re-reading from manifest_root, but
manifest_root = args.manifest.parent() DROPS the filename while --manifest accepts an
arbitrary name -> would read the wrong file for --manifest custom.toml. Now: thread
the hosts (or full path) into provision; a bare re-read does not work.
HIGH (outbound-host default): the initial manifest EXAMPLE still advertised the
cleartext-enabling ["*"] default the corrected schema rejects. Example + appendix now
state absent -> https-only ["https://*:*"], explicit ["*"] -> http+https opt-in.
MEDIUM: Manifest::configured_adapter_names() doesn't exist -> iterate
manifest.adapters.keys() (real BTreeMap field). The three config commands aren't
symmetric (per-command table). Response migration summary said buffering is reserved
for Body::Once on all three WASM adapters -- only Cloudflare streams lazily; Axum,
Fastly, Spin all buffer Body::Stream (fixed + appendix superseded marker).
MASTER-SPEC LINT: DEADLINE_FAR_FUTURE from_secs(7*24*60*60) -> from_hours(168) at both
live sites; Capability enum carries a documented #[expect(arbitrary_source_item_ordering)]
(semantic grouping tied to the matrix); added a prominent §3 directive that all code
blocks are illustrative and must be brought to the strict lint gate before use.
PHASE 1a PLAN: `let v` -> `body_json` (min_ident_chars, reviewer-verified); the three
error.rs tests are not all "exhaustive matrices" (only kind_strings_per_variant is;
the other two are subset checks) -- wording corrected. Deadline block replaced with
the version compile-verified GREEN under the repo's exact lint table.
COMMENTS: stripped section-number / round-N / phase meta-references from all code-block
comments (plan + 894 spec lines) -- comments describe the code, not the planning process.
…consistency Independent review verified the Phase 1a plan end-to-end against the tree and found one real defect, now confirmed here: - The Task 1 / Task 2 test snippets did NOT pass cargo fmt --check as written. Verified with rustfmt at the REAL test-module nesting (inside ): the one-line array-of-tuples rows exceed max_width=100 (~106 cols) and rustfmt rewraps every tuple element onto its own line, plus the message-bearing assert!/assert_eq! and checked_add(..).expect(..) chains. The plan presented these as exact landed code and its Self-Review claimed 'no diff' -- wrong. Replaced both snippets with their rustfmt-canonical multi-line form (re-derived from rustfmt, not guessed); rustfmt --check now exits 0 at real nesting for both blocks. - Spec appendix nit: the resolved-findings table still wrote DEADLINE_FAR_FUTURE = Duration::from_secs(7 * 24 * 60 * 60), contradicting the canonical §3.3.1 def (from_hours(168), which the live sites already use). Made consistent.
The prior meta-ref stripping regex over-reached on comment lines: its empty-paren tidy step ate () off method calls (.is_expired/.enable_ssl/.disable_ssl), bare-§ removal left dangling 'per;'/'per)'/', )' fragments, and one /// collapsed to //////. Repaired 23 comment lines back to grammatical rustdoc (no § back-refs, per the earlier directive -- just correct text). Verified no residual artifacts.
…tent SDK variant
H2 (fail-open, security): from_baked_json did parse + finalize but SKIPPED validate(),
while the real try_load_from_str does parse -> validate() -> finalize(). A crafted `{}`
is valid JSON and parses to a default Manifest with EMPTY capabilities, so an
invalid-but-parseable contract became Present and the gate proceeded against no required
capabilities. Now runs validate(); failure -> Malformed (hard-fail). Added a §5.4
regression-guard row. (finalize only rebuilds derived logging state -- verified in tree.)
H1 (my own regression): last round's cache-bounding used a 1-2-5 grid AND armed the host
timers with the rounded-up bucket, which breaks the headers-phase deadline (that phase
has no cooperative check -- the guest is blocked in the SDK awaiting headers). A 201 ms
budget -> 500 ms bucket = ~299 ms of unpreemptable overshoot. Replaced with a TIGHT
geometric ladder (ratio 1.1): compile-verified (strict clippy + tests) that the result
is always >= real budget (never premature), overshoot < 10%, 97..100 ms collapse to
~1 bucket, and the full 1ms-7day range yields < 300 buckets. 201 ms -> 215 ms now.
Stopped claiming "wall-clock contract unchanged" -- honestly documented the <=10%
headers-phase overshoot as part of Fastly's BoundedCooperative outbound-deadlines
posture, and reconciled the proof, the phase-split prose, and the §5.4 rows.
M6: the "real fastly 0.12.1" table named HttpCacheKeyInvalid, which does NOT exist.
The pinned SDK has HttpRequestCacheKeyInvalid, HttpCacheLimitExceeded,
HttpCacheApiUnsupported. Corrected.
…tract location, test matrix
H3 (Spin can discard a valid early final response): the upload used join!(pump, send)
with pump-failure precedence. If an origin returns 413/401/redirect BEFORE consuming the
full body, it stops reading -> the guest write sees reader-gone -> the pump returned
bad_gateway and DISCARDED the valid response; and a stalled source delayed an
already-available response to the deadline (504). Both violate "completed non-2xx is Ok".
Fixed two ways:
1. Reader-gone in the pump is NOT an error -- end the pump cleanly (Ok) so `send`
surfaces the response.
2. Replaced join! with an ORDERED select: a completed `send` (Ok or Err) IS the
exchange result; a pump SOURCE-error/cap-overflow only wins if it lands before any
response. Compile-verified (pin/select/Either/borrow) in an isolated crate; used the
select-returned future to avoid a double mutable borrow, and no `loop` (never_loop).
Added 3 §5.4 rows: early-final-response not discarded, stalled-source not delayed,
pre-response pump error still surfaces.
M4 (run_demo has no injection seam): run_demo() hardcodes run_app::<App>(), so the
required crafted-JSON gate test is unwritable. Added a generic run_demo_for<A: Hooks>();
run_demo() delegates with the concrete demo App; the test calls run_demo_for::<TestApp>().
M5 (ManifestContract location + stale inventory): §7 still said ensure_capabilities takes
BakedManifest and located the helper in the CLI crate. Corrected: it takes
ManifestContract<'_> (file-backed sites hold non-'static borrows), and both
ManifestContract and BakedManifest::as_contract() live in core beside BakedManifest.
M-test-matrix: empty send_all was Tier 1 only, but the mandatory per-adapter send_all
conformance suite must re-run it (Tier 2) since each adapter implements send_all
independently. Marked Tier 1 + Tier 2.
M7: verified already resolved -- the "prior session" lines are the corrections
("NOT a prior session"), and config push has no residual shared-gate claim.
…st) + plan literal suffix The reviewer verified Phase 1a passes everything in an isolated copy EXCEPT the literal suffix, and caught that TWO rounds of my Fastly fixes rested on a false premise. ROOT CAUSE (verified against fastly-0.12.1 BackendBuilder docs): dynamic-backend names are SESSION-scoped, not global-across-requests. Connections pool across sessions, but each request is a new session with a FRESH namespace. So: - The "request #2 fails on NameInUse" concern that drove the thread_local cache was WRONG -- request #2 is a new session, re-registration is fine. - The "unbounded cross-request cache" concern that drove geometric bucketing was WRONG -- a per-session cache is bounded by fan-out size and discarded each request. Reverted BOTH: the cache is a per-session RefCell FIELD on the per-request client (fresh each session, correct by construction; a cross-request thread_local would carry STALE entries into a reused instance). Identity + host timers use the EXACT ceil-to-ms again (no bucket), which restores the exact headers-phase deadline bound. This resolves: - F2: "Net guarantee" (25ms + rounding) is correct again (no bucket overshoot). - F9: cache lifetime is per-session; fixed "prior session" NameInUse wording. - the H1 overshoot I introduced last round (removed, not just documented). fastly_timeout_ms reverted to plain ceil; §5.4 bucket rows replaced with a per-session-bound row; phase-split prose back to budget (not budget_bucket). F1 (Phase 1a blocker): 502u16/504u16 violate unseparated_literal_suffix (denied; verified 502u16 errors, 502_u16 passes). Fixed to 502_u16/504_u16, added the lint note, and added --all-targets to the task clippy command so tests are linted pre-commit. F6 (my regression): run_demo_for<A: Hooks + App> can't compile (App is a struct). And overriding only manifest_json() is a no-op (default manifest() returns Absent). Replaced with a PURE demo_capability_gate<A: Hooks>() (no blocking server on success); TestApp overrides manifest(). F7 (my regression): {} is a VALID empty manifest (accepted with defaults), so it yields Present, not Malformed. Fixture changed to genuinely-invalid JSON (bad outbound host / duplicate required+optional capability) that parses but fails validate(). F11: config-push gate row said "shared inner op, both entries" -- corrected to typed entry only (the bundled stub errors; gating it enforces nothing).
…ladder, smoke tests F3 (Cloudflare timeout did not cancel the fetch): dropping the raced future does NOT abort the subrequest -- the Workers runtime keeps the POST going after EdgeZero returns 504. Verified worker 0.8.3 exposes AbortController + Fetch::send_with_signal(&signal). §4.2 now issues via send_with_signal and calls controller.abort() on expiry; §8 risk 3 marked resolved. F8 (Spin map_spin_send_err was referenced but unspecified): added the WASI ErrorCode classification mirroring Fastly's SendFailure -- DnsTimeout/ConnectionTimeout/ ConnectionReadTimeout -> 504 (must NOT fall through to 502), transport -> 502, local-invalid -> internal, `_` -> 502. F4 (only Axum had a 502/504 response-synthesis mapping): specified that Fastly and Spin buffered-drain converters also synthesize the platform response from err.status() + into_response(), not a stringly platform error; §5.4 tests 502/504/over-cap/500 per adapter. F5 (Fastly Tier 2 had no transport seam): the recording builder + clock can't script PendingRequest::poll/wait or connect/header hangs. Added a `test-utils` FastlyDispatch trait so tests script the exchange; rows that need real TCP/TLS timing are Tier 3 only. F10 (capability model couldn't express "exact deadlines required"): defined the support-level ladder -- `required` is satisfied by Native OR BoundedCooperative, hard- fails on BestEffort/Unsupported; exact-only need is a deferred outbound-deadlines-exact capability (§8 risk 14), not an ad-hoc "declare exactness". Low: required/optional capabilities validated unique + disjoint (a from_baked_json -> Malformed / config-validate failure); added public smoke tests for Deadline::remaining() /is_expired() using after(ZERO) (no checked_sub underflow on a fresh WASM Instant).
…nown_fields, Spin timeouts H2 (my regression, compile error): OutboundHttpClient: Send + Sync (the handle stores Arc<dyn ..> in http::Extensions, which require Sync), but last round I "corrected" the Fastly cache to a RefCell field -- RefCell is !Sync, so it cannot compile. The ORIGINAL Mutex<HashMap> field was correct. Reverted to a per-session Mutex<HashMap> field on the per-request client: uncontended on the single-threaded WASM guest (satisfies Sync, does not serialize), fresh each request. This is now the third and final correction of a cache model I kept getting wrong from one false premise (names persist across requests) -- the verified truth is session-scoped names + a per-session Mutex field. H3: deleted the stale cross-request/process-scoped cache block (3896) that still contradicted the authoritative per-session section, plus the RefCell heading and the "no Mutex needed" prose. H7 (Spin timeout misclassification): verified wasip3-0.4.0 has FIVE http timeout ErrorCode variants -- DnsTimeout, ConnectionTimeout, ConnectionReadTimeout, ConnectionWriteTimeout, HttpResponseTimeout. map_spin_send_err mapped only three, leaking ConnectionWriteTimeout + HttpResponseTimeout to 502. All five -> 504, with an exhaustive classifier test. H1 (capability declarations fail open): ManifestCapabilities/ManifestOutboundCapability lacked #[serde(deny_unknown_fields)], so a typo (require/host) is silently ignored -> enforcement disabled or broad default invoked. Added deny_unknown_fields to both, and attached the validate_capabilities_disjoint schema validator (rejects duplicates and required∩optional overlap). §5.4 tests typo/duplicate/overlap. Low: purged the last stale "bucketed" wording (identity uses exact ceil-to-ms; the snapshot-vs-arm slack is the pre-existing guard, unrelated to bucketing).
…bility non_exhaustive) H4 (Axum decompression): reqwest's auto-decode matches exact-lowercase content-encoding from one map entry -- it cannot honour the portable contract (case-insensitive GZIP, identity/unknown/stacked/repeated passthrough). Axum now does NOT enable reqwest gzip/brotli; it routes through the SAME shared §3.4.1 decoder as the other adapters, so all four share one decompression contract. H5 (Cloudflare streamed-response expiry did not cancel the fetch): the buffered path aborts via AbortController, but the streamed wrapper only emitted an error chunk. The AbortController now moves INTO the body wrapper and aborts on deadline, chunk-read failure, or early consumer drop -- so a timed-out stream cancels the subrequest, not just stops reading. H6 (Spin buffered uploads were not cancellable): spin_sdk::http::send spawns a detached uncancellable pump even for a buffered Body::Once (which can block on host backpressure after the send future is dropped). ALL Spin uploads -- buffered and streamed -- now use the hand-built wasi:http request + owned in-race pump, so both body kinds are genuinely cancellable and streamed-upload-deadlines stays Native. Mediums: Capability/CapabilitySupport enums -> #[non_exhaustive] and Adapter::capability gets a default returning Unsupported (out-of-tree adapters compiled against older core still build; unknown capability fails closed). Optional capabilities logged at BestEffort AND Unsupported (not just Unsupported). Axum response converter drains async on the Tokio reactor (NOT block_on inside a worker), with a timer-backed-stream test. Tier 2 seam- dependent rows are required (the seam is a deliverable), not waived. CF redirect uses RequestRedirect::Manual (enum, not "manual" string). Spin wasip3 setters use .map_err (they return Result<(),()>, bare ? won't compile). Provision host-data: locked option (a) (add hosts to the provision context). Plan Task 3 renamed/scoped to the five core gates (Phase 1a is additive core-only).

Summary
Adds the EdgeZero outbound HTTP design spec at
docs/superpowers/specs/2026-05-21-outbound-http-design.md. Targets the PR #269 (feature/extensible-cli) baseline — the spec assumes the multi-store manifest, theedgezero_cli::adapter::execute(..)dispatcher, the expandedAdapterActionset,Adapter::provision/ config-validation hooks, Spin SDK 6 / wasip2, and thedemocommand. Earlier appendices that quote the pre-#269 surface are explicitly flagged as historical.Driving pattern
The spec is written against fan-out HTTP workloads — N concurrent outbound requests under a shared wall-clock deadline, results harvested in input order. The driving pattern is treated as a portable substrate; the spec deliberately does not name a single consumer.
Scope
Six driver requirements:
OutboundHttpClienttrait with singlesendand concurrentsend_allon every adapter (Axum, Cloudflare, Fastly, Spin). One handler source compiles unchanged across all four.dispatch_budget(req, now)with explicitnowsnapshot,DEFAULT_NO_DEADLINE_BUDGET = 30s,DEADLINE_FAR_FUTURE = 7 days,BATCH_DISPATCH_SLACK_MAX = 25ms. Fastly's bounded-cooperative semantics are documented with precise overshoot bounds.max + sizeof(current_chunk)worst case, in-flight chunk size source-controlled), pre-append cap checks across inbound + outbound bounded drains. Batch model isΣᵢ request_bodyᵢ.len() + Σᵢ max_response_bytesᵢ.outbound-http,outbound-deadlines,outbound-flexible-phase-budget,send-all-slot-isolation,streamed-upload-deadlines,lazy-streamed-response-passthrough,config-store,kv-store,secret-store). Enforcement runs as five pre-dispatch gates (one insideexecute(..), siblings onrun_provision/run_config_push/run_config_validate/run_demo).MockOutboundClient), Tier 2 (per-adapter translation), Tier 3 (runtime against a local mock origin). Adapter-specific mechanics (Fastly host timers, harvest behaviour, dynamic backend identity) are restricted to Tier 2/3 since Tier 1's mock has no analogue.backend_target() / host_authority() / sni_hostname() / cert_host()are the single source of truth for the host/port/SNI/cert split. Adapters MUST consume these, not re-derive fromreq.uri(). IP-literal HTTPS (RFC 6066 §3) is handled bysni_hostname() == None && cert_host() == Some(ip).Out of scope (explicit non-goals)

The spec was revised through 49 review rounds. The non-normative resolution journal lives in Appendices A through AX. Appendix AR is the round-44 rebase snapshot, superseded by Appendices AS / AT / AU / AV / AW / AX (rounds 44–49).
