Summary

  • append a typed, immutable context_compaction_input_does_not_fit recovery record in the same transaction that closes the call-free failed turn
  • make goal disposition park that proven non-resumable failure immediately with operator guidance instead of spending the 20-attempt automatic-resume budget
  • preserve bounded automatic recovery for transient compaction/provider failures

Meaningfully changed lines: 456 (no lockfile changes).

Validation

  • complete format, workspace check, clippy, doctest, rustdoc, metadata, migration, numeric-bound, panic-gate, invariant, and pinned Markdown checks pass
  • targeted PostgreSQL integration test passes against migration 202608210617
  • complete unit suite reaches this code cleanly; host-only pre-existing failures remain because /tmp is owned by nobody (13 local-socket permission tests) and the host lacks the US/Eastern zoneinfo alias (one current-time test)
  • inherited docs-consistency exception: the live bounds stack cites carrier PR Make numeric-bound declarations fail closed #1125, which is in this stack but not yet in main

Numeric-bound ledger: this slice adds or changes no numeric bound.

Rust coverage (report only)

Report only. This measurement has no threshold, gates no merge, and
fails no check; it exists so untested code stays visible.

Measured suite Outcome
workspace (--all-targets --all-features) success
persistence PostgreSQL (--ignored) success
signalboxd PostgreSQL (--ignored) failure
terminal-client PostgreSQL (--ignored) success
What this number does not measure
  • Doctests. cargo llvm-cov --doctests needs a nightly
    toolchain; this workspace pins stable, so the compile-fail
    sealing proofs and every other doctest are outside the
    denominator.
  • Live smokes, which spend real network requests or
    credentials and are never run here: the tools-github and
    tools-web smokes stay --ignored, and the whole-daemon and
    real-provider terminal smokes are skipped by name above.
  • The Swift native client, which Xcode measures separately.
  • One environment-clearing test in signalbox-tools-exec,
    which instrumenting its supervisor process perturbs. The
    workflow comment on the workspace step states why; rust.yml
    runs that test uninstrumented and gates on it.
  • Dedicated test files. cargo-llvm-cov excludes tests/
    and benches/ targets and *tests.rs modules from the
    report by default, so that test code is counted neither
    covered nor uncovered here. Inline #[cfg(test)] modules
    inside a source file are the exception: they are
    instrumented, and they land on both sides. A test body
    that ran counts as covered, which makes every percentage
    below optimistic; the body of an #[ignore]d test no
    measured suite runs counts as uncovered, which puts test
    lines into the file ranking. Read both tables as close,
    not exact.

P1 Badge Consult the durable cause during reconciliations

This cause-aware selection runs only in the direct failure callback. If the daemon restarts after the failed-turn transaction commits but before that callback disposes the goal, reconcile_success still selects Scheduled; likewise, an ambiguous block commit is reread by reconcile_ambiguous_block, which also unconditionally plans automatic resumption. Both paths therefore arm a resume for a turn carrying context_compaction_input_does_not_fit, defeating the durable parking behavior and potentially repeating the impossible turn until the attempt budget is exhausted. Reuse the cause-aware selection in both reconciliation paths, deriving the failed turn from the current terminal turn or block provenance.
