Icod.Dedit needs clipboard transfers beyond 64 KiB. This implements the approved design as 1.29.0-alpha.1, preserving 64 KiB defaults while allowing applications to opt into independent read/write budgets up to 16 MiB.

Changes

• Add immutable TerminalClipboardOptions to session options, with validated decoded-byte limits and checked frame geometry.
• Encode writes directly into one complete ordered frame; enforce strict UTF-8 byte limits before output.
• Incrementally accumulate larger replies only after exact OSC 52 selection correlation, using the existing input reader and query ownership.
• Bound malformed/oversized reply recovery, preserve trailing input and late-query isolation, and fail unresolved input closed.
• Add explicit CLI read/write/generated fixtures, independent capacity switches, and a consented 131,072-byte compatibility scenario. Help/startup never touches the clipboard; reports omit contents.
• Update public API/XML and fresh-package consumers, roadmap, usage guide, privacy/versioning docs, changelog and alpha notes. Dependencies remain unchanged.

Verification

Linux x64, SDK 10.0.100, Release:

• Solution and compatibility sample build: zero warnings/errors.
• Full unit suite: 2,925 passed per target on .NET 8, 9 and 10, followed by an additional concurrent-session budget test passing on all targets (2,926 unique cases per target).
• TermInfo integration: 15 passed per target.
• Package build, exact headers/licenses, identical cross-TFM API, fresh-package clipboard smoke and compatibility sample smoke passed.
• Existing published DCurses 1.6.0/2.2.0 and Terminal-owned screen acceptance passed on all targets.
• API diff against regenerated 1.28 baseline is additive only.
• Allocation tests cover 64 KiB / 1 MiB / 16 MiB and incremental scanning. The 64 KiB encoder allocates 87,424 bytes versus 262,216 on 1.28.
• Inline author review covered bounds, ownership, malformed recovery, cancellation, disposal, memory growth and public-only consumers.

Contract and remaining release gates

These are local resource budgets; OSC 52 has no capacity handshake or write acknowledgement. Ordinary input/unrelated protocol ceilings remain unchanged. Customized ordinary buffers still need room for the selection prefix; wrong-selection frames retain legacy ordinary handling.

All live clipboard environments remain NotRun. Whole-session peak-memory profiling and final GitHub matrix results remain explicit qualification gates; component measurements and analytical storage bounds are documented separately. Maintainer owns stable promotion, merge, tags and publication.
