Goal: improve the contract-review assistant using context window without breaking protected slices.

Mechanism reminder for context window: Tokenize inputs; if over limit, truncate/summarize/retrieve selectively; the model attends only to what remains; output tokens also consume the budget.

Baseline and shock: A 32k window with 8k system+tools, 12k retrieved exhibits, 6k history leaves ~6k for the draft—and less if tokenization is heavier than word count suggests.

Tradeoff in play for context window: More evidence can help and can crowd out instructions. Summaries save space and can drop obligations. Long windows raise cost and attention dilution risk.

Ship decision: Pin 2k system tokens, budget 14k exhibits via retrieval, summarize history beyond 4k, abort if obligations pack fails checksum.

Rollback triggers for context window must cite overflow rate, obligation-coverage on long contracts, p95 tokens in, cost per review. If you cannot name a tolerated regression on the contract-review assistant, do not promote the change.

Keep the context window decision record beside the contract-review assistant code paths that implement it. Future you will not remember why a default exists unless the evidence is linked from the config for context window.

Also pin one numeric memory from this context window chapter: A 32k window with 8k system+tools, 12k retrieved exhibits, 6k history leaves ~6k for the draft—and less if tokenization is heavier than word count suggests. That number is not decoration; it is a template for how claims about context window on the contract-review assistant should look in design docs.

People confuse context window with neighboring buzzwords when debugging the contract-review assistant. Before changing prompts, ask whether the broken stage was evidence gathering, the context window judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried context window and it failed”) that blocks the next team on the contract-review assistant.
