## Entries

- [Event and Messaging Consistency](https://banes-lab.com/records/algo/event-and-messaging-consistency.md): For asynchronous systems, validate event contracts, message schemas, idempotent consumers, outbox publication, correlation metadata, ordering guarantees, retry behavior, and dead-letter handling.
- [Observability and Auditability](https://banes-lab.com/records/algo/observability-and-auditability.md): Attach correlation and causation identifiers, emit logs, metrics, traces, alerts, audit records, and runtime health signals, then reconstruct behavior as a causal execution graph.
- [Causality and Ordering](https://banes-lab.com/records/algo/causality-and-ordering.md): Model distributed events as a dependency graph, attach causation metadata, validate happens-before relationships, and use sequence numbers, Lamport clocks, or vector clocks when physical timestamps are insufficient.
- [Streaming Dataflow](https://banes-lab.com/records/algo/streaming-dataflow.md): Process data through forward-only stages, preserve bounded memory, apply backpressure, checkpoint state where needed, and prefer stateless processing unless state is explicitly modeled.
- [Architectural Contract Kernel](https://banes-lab.com/records/algo/architectural-contract-kernel.md): For any programmatic system, identify architectural concerns, define explicit contracts for each concern, bind implementations to those contracts, validate invariants, observe behavior, and evolve through versioned change.
- [Event Messaging](https://banes-lab.com/records/algo/event-messaging.md): Convert state changes into events, classify domain versus integration events, publish through durable channels, consume idempotently, and preserve ordering where required.
- [Causality Ordering](https://banes-lab.com/records/algo/causality-ordering.md): Model events as a dependency graph, assign causal metadata, preserve happens-before relationships, and reject or compensate for invalid ordering.
- [Automation Priority Ordering](https://banes-lab.com/records/algo/automation-priority-ordering.md): Convert breaking points into urgency scores using severity, projected time-to-break, affected scope, and expected maintenance cost, then sort candidate migrations.
- [Dependency Linearization](https://banes-lab.com/records/algo/dependency-linearization.md): Detect cycles in the sequential Z-graph, block if any exist, and otherwise order the phases in topological Z-order with a stable tie-breaker so execution order is fixed by dependency alone.
- [Living Plan State](https://banes-lab.com/records/algo/living-plan-state.md): Treat the plan as durable append/update-only state — tasks carrying status and grounding, a considerations backlog, and a dismissed-key set — maintained every turn and re-delivered on restart, so anything discovered mid-pass is retained instead of falling out of scope.
- [Boundary Reconciliation](https://banes-lab.com/records/algo/boundary-reconciliation.md): Capture considerations during a phase but act on them only at the phase boundary — triage each open consideration against code and canon into a confirmed task or a dismissed resolved-false key, deduping new opens against the confirmed and dismissed sets before triage.
- [Versioned Turn Provenance](https://banes-lab.com/records/algo/versioned-turn-provenance.md): Persist each accepted model turn as an append-only, mode-tagged, schema-versioned, causally ordered record with change-only provenance, so the turn history is a queryable, auditable log and a turn is never graded against a schema version its stored state never saw.
- [PAG Structure Declaration](https://banes-lab.com/records/algo/pag-coordination-construct.md): Make a document's structure explicit with the declaration that names it: a DAG for a dependency graph, a STATE_MACHINE for a lifetime or a set of derived states, a PRIORITY_QUEUE for a ranking, a FLOWCHART for the rendered projection of a declared structure, and for a shared surface the coordination model's SURFACE, RECORD and ITEM with their typed edges, derived states and the one post-and-wait operation, so ordering, ownership and state are declared as structure rather than narrated as prose.
- [Sequential Chain Duplication](https://banes-lab.com/records/algo/sequential-chain-duplication.md): For each class in the role family, extract the ordered sequence of orchestration steps, align sequences across the family, and surface repeated ordered chains that no textual-duplication scan would catch.
- [Causal Wiring Duplication](https://banes-lab.com/records/algo/causal-wiring-duplication.md): Extract cause-to-effect edges (event to handler, failure to recovery, state change to reaction) per class, match trigger/reaction pairs across the role family, and surface repeated causal wiring that a base policy would centralize.
- [Migration Ordering](https://banes-lab.com/records/algo/migration-ordering.md): Sort target classes by complexity from lowest to highest, migrate simpler implementations first, and use early migrations to validate the abstraction before complex adoption.
- [Stage Ordering](https://banes-lab.com/records/algo/stage-ordering.md): Build the runnability DAG from dependsOn, topologically order the cascade by the invalidates relation so fixes point forward, partition into normalization prefix, structural band, and semantic suffix, and permit back-edges only inside the suffix.
