The composer ring, percentage, and `~used / capacity` header read
`contextPressure.pressureTokens`, which moves only when a request reports
usage. Compaction reports none — compact-basic summarizes through a direct
`ctx.llm.stream()` call and appends only its own `compact/*` records plus the
replacement `user/message` — so the meter was frozen across the one action
taken to change it. Driving a real `compactNow` through the agent loop:
BEFORE compact: ring=4% header=~4227/100000 rows=[18, 0, 4365]
AFTER compact: ring=4% header=~4227/100000 rows=[18, 0, 286]
The composition rows fell 93%; the ring did not move, and would not until an
entire further turn completed. The panel then contradicted itself by more than
an order of magnitude at exactly the moment a reader opens it.
`contextPressure` now also publishes `projectedTokens`: the provider sample
plus the heuristic repricing of everything the surface gained or lost since
that sample, clamped at zero, folded through the shared `surface-fold.ts`. The
sample is stamped before the same event joins the surface, so an
`assistant/message` anchors against the surface its own request carried. Only
the delta is estimated, so the figure stays provider-anchored — the estimator's
CJK and JSON-schema underpricing stays out of the occupancy number — while
reacting the moment content lands or a span is shadowed. Same run after:
BEFORE compact: ring=4% header=~4323/100000 (pressure=4227, projected=4323)
AFTER compact: ring=0% header=~ 244/100000 (pressure=4227, projected= 244)
`contextOccupancy` prefers the projected figure and falls back to the bare
sample, so a projection restored from a pre-field checkpoint degrades to the
old behavior rather than disappearing. `stateVersion` moves to 3.
llm/ — LLM capability family
English | 中文
The LLM seam and its provider adapters. The interface package (llm) owns the abstract service, the content-block vocabulary, and the stream-chunk assembler; the adapters are concrete implementations that register on ctx.llm. All product packages.
| Package | Role | ctx key |
|---|---|---|
llm/ |
Abstract LLM service + content-block vocabulary + chunk assembler | ctx.llm |
token-meter/ |
Replay-aware request and surface token measurement | ctx.tokenMeter |
llm-retry/ |
Exact-provider normal or unbounded request retry policy | (listens to agent/request-error) |
llm-deepseek/ |
DeepSeek API adapter (direct fetch + eventsource-parser SSE) | (registers on ctx.llm) |
llm-pi-ai/ |
Multi-provider adapter via @earendil-works/pi-ai |
(registers on ctx.llm) |
The interface lives at llm/llm/; adapters, retry policy, and the reusable token meter are flat siblings under the group. Requests route by provider, while model is passed through to the selected adapter. The route-owning adapter supplies retry policy and resolves available exact-model identity, context capacity, and reasoning metadata; the retry executor and token meter remain provider-agnostic. A new provider adapter registers one or more provider routes on ctx.llm without touching the consumers. See twin LLM adapters for the two shipping implementations, the replay token meter Agent Note for measurement ownership, and the routed model context Agent Note for capacity and compaction-policy ownership.
