This ensures that a write from another agent that lands while the read is in flight is correctly ordered after the read and reported as stale, instead of being silently absorbed. The change also moves the read recording logic into a `FileStateCoordinator` method and updates the `ReadStamp` documentation to clarify the timestamp semantics.

Resolving the +hostname again in an HTTP client reopens the DNS-rebinding gap. Keep the URL's +hostname for TLS SNI and the Host header. Validate every redirect destination +before following it. + +The guard rejects loopback, private, link-local, multicast, documentation, +shared-address, local names, IPv4-mapped IPv6, and NAT64 translation prefixes. +Its lexical checks reject userinfo, backslashes, percent-encoded hosts, and +IPv6 URL literals because downstream URL parsers can interpret those forms +differently. This crate supplies no HTTP transport, so connection pinning and +redirect policy remain the caller's responsibility. diff --git a/crates/tinytools-std/src/url_guard/mod.rs b/crates/tinytools-std/src/url_guard/mod.rs index 7f0ad06..8565aa6 100644 --- a/crates/tinytools-std/src/url_guard/mod.rs +++ b/crates/tinytools-std/src/url_guard/mod.rs @@ -449,6 +449,10 @@ pub fn is_non_global_v6(v6: std::net::Ipv6Addr) -> bool { || (segs[0] == 0x2001 && segs[1] == 0x0db8) || (segs[0] == 0x0100 && segs[1] == 0 && segs[2] == 0 && segs[3] <= 1) || (segs[0] == 0x2001 && segs[1] == 0x0002 && segs[2] == 0) + // Local-use translation (RFC 8215) and the well-known NAT64 prefix + // can embed addresses that translate to private IPv4 destinations. + || (segs[0] == 0x0064 && segs[1] == 0xff9b && segs[2] & 0xff00 == 0x0100) + || (segs[0] == 0x0064 && segs[1] == 0xff9b && segs[2] == 0 && segs[3] == 0) || (segs[0] & 0xfff0) == 0x3ff0 || segs[0] == 0x5f00 || v6.to_ipv4_mapped().is_some_and(is_non_global_v4) diff --git a/crates/tinytools-std/src/url_guard/test.rs b/crates/tinytools-std/src/url_guard/test.rs index 9e7866a..1a3c1dd 100644 --- a/crates/tinytools-std/src/url_guard/test.rs +++ b/crates/tinytools-std/src/url_guard/test.rs @@ -322,6 +322,14 @@ fn blocks_ipv6_documentation_range() { assert!(is_private_or_local_host("2001:db8::1")); } +#[test] +fn blocks_nat64_translation_prefixes() -> anyhow::Result<()> { + assert!(is_private_or_local_host("64:ff9b:1::7f00:1")); + assert!(is_private_or_local_host("64:ff9b::7f00:1")); + assert!(!is_private_or_local_host("2001:4860:4860::8888")); + Ok(()) +} + #[test] fn allows_public_ipv6() { assert!(!is_private_or_local_host("2607:f8b0:4004:800::200e")); diff --git a/crates/tinytools/src/collapse/mod.rs b/crates/tinytools/src/collapse/mod.rs index 5feeb08..9a2bd9a 100644 --- a/crates/tinytools/src/collapse/mod.rs +++ b/crates/tinytools/src/collapse/mod.rs @@ -111,6 +111,7 @@ pub fn validate_actions(actions: &[CollapsedAction<'_>]) -> Result<(), CollapseE pub fn merge_action_schemas(actions: &[CollapsedAction<'_>]) -> Value { // Every distinct definition of each property, in first-seen order. let mut definitions: BTreeMap> = BTreeMap::new(); + let mut merged_defs = Map::new(); // Track which actions mentioned each property so a shared field reads as // shared rather than as belonging to whichever action happened to be first. let mut owners: BTreeMap> = BTreeMap::new(); @@ -126,8 +127,17 @@ pub fn merge_action_schemas(actions: &[CollapsedAction<'_>]) -> Value { } owners.entry(name.clone()).or_default().push(entry.action); let known = definitions.entry(name.clone()).or_default(); - if !known.iter().any(|existing| same_definition(existing, spec)) { - known.push(spec.clone()); + let mut property = spec.clone(); + rewrite_local_refs(&mut property, entry.action); + if !known.iter().any(|existing| same_definition(existing, &property)) { + known.push(property); + } + } + if let Some(defs) = schema.get("$defs").and_then(Value::as_object) { + for (name, definition) in defs { + let mut definition = definition.clone(); + rewrite_local_refs(&mut definition, entry.action); + merged_defs.insert(format!("{}_{}", entry.action, name), definition); } } } @@ -189,11 +199,38 @@ pub fn merge_action_schemas(actions: &[CollapsedAction<'_>]) -> Value { }), ); - json!({ + let mut result = json!({ "type": "object", "properties": Value::Object(merged), "required": [ACTION_KEY] - }) + }); + if !merged_defs.is_empty() { + result["$defs"] = Value::Object(merged_defs); + } + result +} + +/// Namespace member-local JSON Schema definitions so merged properties keep +/// resolving their references without collisions between actions. +fn rewrite_local_refs(value: &mut Value, action: &str) { + match value { + Value::Object(object) => { + if let Some(Value::String(reference)) = object.get_mut("$ref") { + if let Some(name) = reference.strip_prefix("#/$defs/") { + *reference = format!("#/$defs/{action}_{name}"); + } + } + for child in object.values_mut() { + rewrite_local_refs(child, action); + } + } + Value::Array(values) => { + for child in values { + rewrite_local_refs(child, action); + } + } + _ => {} + } } /// Whether two property schemas constrain the same thing, ignoring the From 77204984e009e1b42e5da58612f520c87dcd6386 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Wed, 30 Sep 2026 09:28:49 +0300 Subject: [PATCH 26/51] feat(collapse): namespace member definitions to avoid collisions When merging action schemas, definitions from different members could collide if they shared the same name.
