The suite covers +lost leases, crashes on either side of the dispatch boundary, exact recorded +result replay, duplicate claims, and cancellation that persists the partial +outcome. `testing::tenant_isolation` uses matching thread/call IDs in separate +organization and workspace scopes over shared storage. + +The filesystem host (`maestro-dex-host --test recovery_contract`) and hosted +PostgreSQL host (`dex-runtime --test postgres recovery_contract`) run the same +assertions. The latter uses real `PgLog` and `DexEffects` over `PgLedger`, +requires PostgreSQL, and refuses all external calls. The model and mutation +are deterministic probes. These tests prove port recovery and persisted replay; +they do not prove process-kill/fsync durability, live provider reconciliation, +or cross-process locking for the single-process local effect ledger. + +After the normal build-capacity prerequisite, focused commands are: + +```bash +cargo test --manifest-path products/maestro/Cargo.toml --locked -p maestro-dex-host --test recovery_contract +scripts/ci/run-with-postgres cargo test --manifest-path rust/Cargo.toml --locked -p dex-runtime --test postgres recovery_contract +``` + ## What this crate will never contain - Surface logic: no Slack, Teams, web or renderer code, and no per-surface diff --git a/vendor/dex-loop/src/context.rs b/vendor/dex-loop/src/context.rs index 4736fdb4e..669d97dcf 100644 --- a/vendor/dex-loop/src/context.rs +++ b/vendor/dex-loop/src/context.rs @@ -49,7 +49,7 @@ pub enum Message { impl Message { /// A rough size in bytes, for compaction thresholds. - pub fn size(&self) -> usize { + pub(crate) fn size(&self) -> usize { match self { Message::User { text, .. } | Message::Summary { text } => text.len(), Message::Assistant { @@ -159,7 +159,7 @@ pub struct ToolEvidence { impl ToolEvidence { /// Exact owner ToolFinished event, independent of the grouped history cursor. - pub fn cursor(&self) -> Cursor { + pub(crate) fn cursor(&self) -> Cursor { self.cursor } } diff --git a/vendor/dex-loop/src/engine.rs b/vendor/dex-loop/src/engine.rs index b2a331faf..ab528d714 100644 --- a/vendor/dex-loop/src/engine.rs +++ b/vendor/dex-loop/src/engine.rs @@ -941,7 +941,10 @@ where if !ctx.interaction_mode().tools_allowed() { return Ok(()); } - if prefetch.started.len() != index || call.tool.as_str() == TOOLS_SEARCH { + if prefetch.started.len() != index + || call.tool.as_str() == TOOLS_SEARCH + || call.tool.as_str() == crate::GRC_GRAPH_TOOL_NAME + { return Ok(()); } let Some(spec) = self.offered_spec(ctx, &call.tool) else { @@ -1212,6 +1215,13 @@ where ClientToolOutcome::Exit(exit) => return Ok(Some(exit)), } } + if call.tool.as_str() == crate::GRC_GRAPH_TOOL_NAME + && let Err(reason) = crate::grc_context::admission(ctx, call) + { + prefetch.reads.discard(index); + self.finish(ctx, call, ToolResult::error(reason)).await?; + continue; + } // Current policy first, even for a decided call: a revoked // grant or changed policy denies it. let remaining = self.budget.wall.saturating_sub(run_started.elapsed()); @@ -1928,6 +1938,7 @@ where call: &ProposedCall, result: ToolResult, ) -> Result<(), Fenced> { + let result = crate::grc_context::finish(ctx, call, result); let mut events = Vec::new(); match self.tools.model_usage(ctx, call, &result).await { Ok(Some(usage)) => { diff --git a/vendor/dex-loop/src/engine/codemode.rs b/vendor/dex-loop/src/engine/codemode.rs index ebc265da8..5b63eb1ca 100644 --- a/vendor/dex-loop/src/engine/codemode.rs +++ b/vendor/dex-loop/src/engine/codemode.rs @@ -62,6 +62,7 @@ where !matches!(entry.executor, ExecutorKind::Client | ExecutorKind::User) && entry.name.as_str() != agent_codemode::TOOL_NAME && entry.name.as_str() != TOOLS_SEARCH + && entry.name.as_str() != crate::GRC_GRAPH_TOOL_NAME }) .map(|entry| agent_codemode::Tool { name: entry.name.to_string(), diff --git a/vendor/dex-loop/src/grc_context.rs b/vendor/dex-loop/src/grc_context.rs new file mode 100644 index 000000000..e007aa92b --- /dev/null +++ b/vendor/dex-loop/src/grc_context.rs @@ -0,0 +1,147 @@ +//!
