tiergraph 0.9.0

• Added exact split and merge operations for nested ordered-containment containers.
• Added checked link accounting for plain, journaled, clock-aware, and derived edits.

• Added byte-preserving tgdb bundle import and export with explicit missing-payload handling.
• Added typed tgdb blob metadata columns and content-checked queries.
• Added explicit tgdb payload inspectors with bounded nested graph indexing.
• Added tgdb history pruning, retired-instance purging, payload pins, and safe garbage collection.
• Added ordered tgdb schema migrations and consistent atomic backups.
• Added synthetic tgdb corpus-loop measurement of time, memory, storage, history, and replay.

Changed

• Made grammar-chart paths refuse leading-plus digit segments as noncanonical.
• Indexed sparse exact-equality pattern alternatives while preserving declared order and scan fallback.
• Reduced span-matching work for large bounded repeats without changing completed results.
• Made shifts enforce common containment ancestry and contiguous child seams by default.
• Made item and relation removal refuse live dependencies before changing an editor.
• Replaced projection-witness graph-distance admission with the built-in atom-multiset lower bound.
• Made DistanceInterval.lower_bound_method required for nonexact results.
• Capped general graph-distance lower bounds at the cheapest container regrouping operation.
• Made GrammarChartProfile expose its graph and root directly.
• Made FoldDeclaration refuse repeated roots and Equals require tuple literals.
• Made Spans predicate binding resolve the other tier before evaluation.
• Made offset-profile JSON refuse both or neither of extent and end as a staged shape error.

Fixed

• Kept default package imports within 5% of 0.8.0 by loading opt-in public surfaces on first use.
• Restored lazy package-attribute access for noncolliding secondary modules.
• Selected Praat TextGrid long or short syntax from the body independently of the header spelling.
• Made capped walks report truncation only when a fresh node is omitted.
• Removed false pending watermarks for start-anchored patterns in open-left scopes.
• Refused CLI annotations when no output can retain them.
• Kept journal provenance on durable acted-on subjects and retired it with those subjects.
• Preserved relation-subject facts while clock editors rebuild binding relations.
• Checked protected layers against final candidates, including provenance writes.
• Preserved undo and redo stacks when restoration or dry-run rollback fails.
• Reconstructed JSON attribute and layer-fact edits atomically.
• Reported only references whose subjects departed an edit.
• Reported donor-side crossing relations and facts without coordinate ambiguity.
• Preserved surviving subtree-swap boundary values and reported only actual losses.
• Required linear identified subtree correspondence and preserved the source durable ID.
• Made carried polyadic crossings refuse invalid flattening or trimming.
• Made checked editors refuse unreported link withdrawal and accept reported endpoint trimming.
• Applied shift ancestry and boundary reporting to every affected containment seam.
• Made container regrouping preserve cross-tier targets and exact semantic inverses.
• Recognized lossy container merges and changed-survivor merges as one semantic difference.
• Reported complete clock replacements in source coordinates with exact durable targets.
• Made layer reads resolve coordinate and durable references consistently.

Documentation
