Option B is the fastest route to a real +local product, but every orchestration feature then has to be built twice and +the two runtimes drift. Option C costs more up front and leaves a single +definition of session behaviour; it is also the only path that keeps Option D +open later without committing to it now. Option A is worth a short spike only +to test whether "one command" alone moves adoption. + +### Option C pays off without a local runtime + +Lifting orchestration out of the Temporal workflow improves the hosted runtime +even if no local runtime follows: + +- **Testability.** Admission racing, preparation, promise polling, emission + retry, the cancel watchdog and continue-as-new gating are today testable only + through Temporal, and some failures (such as the custom-waker restriction, + TMPRL1100) surface only in live suites. As a plain state machine they get + fast unit tests and replay vectors, as the engine already has. +- **Smaller determinism surface.** Only the thin interpreter has to obey + Temporal's workflow rules, not about 20k lines of orchestration. +- **Less SDK exposure.** The Temporal Rust SDK is at 0.4.0. A thinner shell + limits how much code each SDK upgrade touches. +- **One copy of session behaviour.** `test-support`'s `SessionRunner` already + duplicates hosted behaviour by hand (its prompt-refresh fallback "mirrors the + hosted product"). With a shared `sessions` crate, eval and tests run the + production orchestration. +- **Proven pattern.** `bots::controller::state` is already a pure state machine + inside a Temporal shell; sessions would follow the same pattern. + +The cost is a refactor of live-validated code.

The new work is the extracted orchestrator and the substrate under it. The +CLI and web UI need no changes to talk to either runtime. + +### Crate layout + +The orchestration gets its own crate rather than living in the engine: + +| Crate | Role | +| --- | --- | +| `harness` (renamed from `engine`) | Lightspeed's native agent loop: events, session state, context, tool planning, `CoreAgentDrive`. Deterministic and event-sourced. | +| `sessions` (new) | Sans-IO session orchestration: admission inbox, run slot, preparation steps, promise sources, emission outbox, workflow-start dedupe, wake computation, cancel watchdog. Depends on `harness`. | +| `temporal-workflow` | Thin interpreters that run `sessions`, `bots` and `channels` state machines on Temporal. | +| `temporal-runtime` (renamed from `temporal-server`) | Activities, roles and Temporal wiring. | +| `local-runtime` (later) | Tokio interpreter of `sessions` over SQLite, filesystem CAS and embedded envd. | + +Why `sessions` is separate from `harness`: + +- **Different state models.** Harness state is reduced from the event log; + replaying the log reconstructs it. Orchestration state is in-flight + bookkeeping (pending admissions, undelivered emissions, start dedupe, timers) + that is carried across continue-as-new and partly derived from harness state. + Mixing them blurs the "replay the log, get the state" invariant. +- **Vocabulary.** [External harness sessions](../p185-external-harness-sessions.md) + uses "harness" for what owns model calls, context, tools and the inner loop, + and gives Lightspeed admission, orchestration, access policy and supervision. + That maps onto `harness` and `sessions` respectively. Keeping orchestration + above the harness also leaves room to drive an external harness through the + same `sessions` machinery later. +- **Naming convention.** `bots`, `channels` and `environments` already hold + their domain's pure state machines and policy; `sessions` matches. + +A later split could also move the gateway's service layer (about 23k lines, +little Temporal coupling) out of `temporal-runtime` into its own crate once a +`SessionControl` trait exists, so both runtimes serve the API from the same +code. That is independent of the renames. + +### A sync core with async interpreters + +`sessions` should be a synchronous state machine: inputs such as "admission +arrived", "activity completed" or "timer fired"; outputs such as start or +cancel an activity, set a timer, signal or start a workflow, roll over. Each +runtime provides a small async interpreter that owns the racing and the +plumbing. Shared async code generic over a host trait (`start_activity`, +`timer`, `next_admission`, `select`) is a real alternative, but the sync core +is preferred because: + +- **Temporal's rules stay out of shared code.** Under Temporal, await order, + `select` and combinators must be deterministic on its executor. Shared async + code would have to obey that even on tokio, where nothing enforces it, and + violations surface only under Temporal. A machine without futures cannot + violate them. +- **Racing becomes explicit input.** The hard behaviour is what happens when + an admission, cancel or approval arrives during a model or tool call. In + async code that is a `select` whose semantics differ between executors + (branch order; dropping a future versus Temporal's explicit cancellation and + waiting for its result). As ordered inputs, interleavings are testable, + including the awkward ones. +- **State is already a value.** Continue-as-new carry, and a local restart, + need the orchestration state as a serializable struct. Async code keeps it in + future stack frames and needs hand-extracted carry state, which is what + `AgentSessionContinuationState` does today. +- **Cheaper tests.** Feed input sequences, assert emitted commands; no fake + executor or timing. + +Costs: state machines invert control, so linear multi-step flows (such as the +preparation retry loop) read worse than top-to-bottom async code. Versioning +is not avoided either: changing what the machine decides still changes the +commands in Temporal history. The bot controller's split is the working +precedent: decisions in a sync core, racing in a small async shell. Linear +steps that never race can stay async in the interpreter rather than being +forced into states. + +To settle it with evidence rather than preference, the first step of the +extraction ports one slice both ways (the wait loop plus admission racing +against a running activity) and compares the code and its tests. + +## What a local version would take + +A useful local v1 is about eight work items, assuming its scope is interactive +sessions only. Bots, chat channels, schedules, Platform login and +multi-universe tenancy stay hosted features. Those are always-on, multi-user +concerns, and they account for most of the Temporal surface we would otherwise +have to replace (bot controller, trigger fires, conversations, Schedules, +connector task queues). + +In scope for local v1: sessions and runs; steer, cancel and approvals; local +files and shell; MCP; skills and profiles; sub-agents; resuming a session days +later. The public API stays identical, so the CLI TUI and the web UI work +unchanged. + +The effort figures are engineer-weeks for someone who knows the codebase, at +review-level confidence. The "Effort" column assumes Option C; the last column +notes where Option B differs. + +| # | Work item | What exists | What is new | Effort | Option B instead | +| --- | --- | --- | --- | --- | --- | +| 1 | Local backend behind the public API | `AgentApiService` trait (about 119 methods, many with "unavailable" defaults) and a generic `dispatch_json_rpc` in `crates/api` | `LocalAgentApi` implementing the session, run, context, events, VFS and models subset. The CLI calls it in-process; `lightspeed serve` exposes it to the web UI. | 3–4 | Same | +| 2 | Session orchestrator | `CoreAgentDrive`; `SessionRunner` (synchronous drive-until-quiescent); the Temporal session workflow | Admissions handled while a model or tool call runs (steer, cancel, approvals), awaits and timers, promises, queued runs, sub-agents spawned in-process | 8–12, which includes reshaping the hosted workflow | 5–7 on its own, then every later feature built twice | +| 3 | SQLite store | Store traits in `engine`, `vfs`, `environments`, `auth`, `mcp`, `profiles`; `store-pg` as the reference | A `store-sqlite` crate with one-file migrations. jsonb containment becomes `json_each` or filtering in the app; `text[]` becomes JSON; advisory locks become a single-writer process lock. | 3–5 | Same | +| 4 | Filesystem CAS + collection | `FsBlobStore` (sha256 layout) | Wire it in; reference roots and sweeps without Postgres | 1 | Same | +| 5 | Local shell and process tools | envd (12k lines) runs on laptops today; the in-process `ProcessExecutor` is a placeholder | Embed envd as a library over an in-memory transport, or spawn it as a sidecar. Default the active environment to the working directory. | 2–3 | Same | +| 6 | Permission model for a user's own machine | MCP approvals (`AwaitingApproval`, parked runs) | Approvals for shell and writes outside the workspace, with allow rules per session and per directory. Codex and Claude Code users expect this. | 2–3 | Same | +| 7 | Identity and configuration | Single-user auth mode; model defaults; `connect` profiles in the CLI | An implicit local universe and actor; provider keys from environment variables or the OS keychain; a data directory such as `~/.lightspeed` | 1–2 | Same | +| 8 | Packaging and tests | Release pipeline for envd (musl builds); replay vectors | One `lightspeed` binary (TUI by default, plus `serve`); the substrate-neutral test suite run against both substrates | 2–3 | Tests per runtime | + +Total: about 22–33 engineer-weeks for Option C, or 19–28 for Option B before +the duplication cost. With two people in parallel, that is roughly three to +four months of calendar time; the spike in the sequence below runs alongside +the first phase. + +Two items are mostly mechanical. The gateway's Temporal calls are concentrated +in `workflow.rs` and `session_lifecycle.rs` (start, `submit_admissions`, +`status` polling, describe, terminate). Putting them behind a small +`SessionControl` trait would let the hosted gateway and the local backend share +most of the 19k-line service layer. The activity helpers return Temporal error +types (`ActivityError`, `ApplicationFailure`), so they need a neutral error +type before the local substrate can call them. + +## Risks and open questions + +The biggest risk is not the database swap. It is that two runtimes slowly +disagree about what a session does. + +**Risks** + +- **Semantic drift.** Steering, cancellation, promise deadlines and sub-agent + budgets have been hardened against live Temporal suites. A second runtime + needs the same conformance suite, written against the substrate-neutral API + and run against both substrates in CI. +- **Crash and sleep semantics.** Today Temporal retries an activity interrupted + by a worker restart. Locally, a closed laptop lid or a killed process leaves + an LLM call or shell command half-done. We need an explicit rule, probably: + retry model calls, and mark interrupted shell commands as interrupted rather + than re-running them. This overlaps the parked idempotency work for tools. +- **Two writers on one data directory.** Two CLI windows on the same session + need either a file lock per session or one local daemon that owns the store. + Codex and Claude Code avoid this by being one process per conversation. +- **Every schema change twice.** Each `store-pg` migration needs a SQLite twin. + The release metadata currently pins one schema revision. +- **Shared orchestrator under Temporal's rules.** The shared code must stay + deterministic and avoid custom wakers (the TMPRL1100 constraint). The sync + core described under [A sync core with async interpreters](#a-sync-core-with-async-interpreters) + is the mitigation; the risk is that awkward flows get forced into states. +- **Plugin contract.** The workflow-tool contract is defined in Temporal terms + (signals, queries, task queues). External plugin workflows would not run + locally unless the contract gets a second, non-Temporal binding. + +**Open questions** + +- [ ] Is the adoption blocker really infrastructure, or also the first-run + experience (keys, environments, profiles)? Option A answers this cheaply. +- [ ] Should a local session be movable to hosted, e.g. `lightspeed push`? + Sessions are event logs plus CAS, so export and import look plausible, and + that would make local an on-ramp to hosted rather than a fork. +- [ ] What is Lightspeed's differentiator against Codex, Claude Code and Pi on + a laptop? Candidates: provider-native multi-model sessions, durable + resumable sessions, VFS workspaces, sub-agents, and the same agent later + running as a hosted bot. +- [ ] Should local sandbox shell commands (macOS seatbelt, Linux namespaces), + or rely on approvals alone at first? +- [ ] Would hosted ever drop Temporal (Option D)? If not, Option C's main + payoff is a single definition of behaviour, not portability. + +## Suggested sequence + +Because the extraction is worth doing on its own, it does not have to wait for +the spike; the spike gates only the local substrate. Durations are calendar +weeks for two engineers. + +| Phase | Duration | Work | Gate after | +| --- | --- | --- | --- | +| 0 · Spike | 2–4 weeks, in parallel with phase 1 | CLI over `SessionRunner`; in-memory or SQLite store; embedded envd; try with design partners | **Go / no-go on local:** spike used on real tasks | +| 1 · Extract `sessions` | 5–7 weeks | Port one slice both ways and pick sync core or async host trait; sans-IO orchestrator; thin Temporal interpreter; `SessionControl` trait; neutral activity errors; `engine` → `harness` and `temporal-server` → `temporal-runtime` renames | **Hosted unchanged:** live Temporal suites green on the thin interpreter | +| 2 · Local substrate | 5–7 weeks | SQLite store; tokio interpreter of `sessions`; shell approvals; one-binary packaging | **Parity:** conformance suite green on both substrates | +| 3 · Beta and bridge | 2–3 weeks | Public local release; push session to hosted; docs and onboarding | Then revisit Option D | + +The spike is throwaway-tolerant: wire the existing CLI to an in-process +`SessionRunner` with an embedded envd and put it in front of a few design +partners to test the adoption hypothesis. Meanwhile, extract `sessions` while +hosted is its only consumer, so live suites prove nothing changed. If the spike +does not land, phase 1 still stands on its own and phases 2 and 3 wait. If it +does, the local substrate is built on the extracted core, and the spike's +`SessionRunner` is replaced by the production orchestration. diff --git a/docs/roadmap/p186-provider-safe-media-and-context-entry-redaction.md b/docs/roadmap/p186-provider-safe-media-and-context-entry-redaction.md new file mode 100644 index 000000000..ace0dc2d8 --- /dev/null +++ b/docs/roadmap/p186-provider-safe-media-and-context-entry-redaction.md @@ -0,0 +1,472 @@ +# P186 — Provider-safe media and context entry redaction + +**Status:** Implemented and live-verified, 2026-10-01 (all four slices). +Revises the request-time media rules of +[tool result media](p171-tool-result-media.md). + +## Outcome + +A session can recover when its active context no longer fits or is no longer +accepted by its provider, while preserving its durable history and as much +useful information as possible. Known media limits are handled before sending +the request. If a provider rejects a request for a reason the runtime cannot +predict, the failure says so plainly. +An operator can neutralize an offending entry with one public API call that +appends an ordinary event, instead of rewriting the session log. + +Five changes deliver this, with provider-specific lowering and continuation: + +1. Every image is sent as a normalized copy for the model, bounded in pixels + and bytes. Stored originals are unchanged. +2. Each request keeps its media within one fixed, provider-independent media + budget, omitting the oldest media when it would not fit. +3. A provider rejecting a request is reported as a distinct run failure, + `RequestRejected`, carrying the provider's message word for word. +4. `session/context/replace` replaces the text of chosen entries in place, + by entry ID, so an operator can neutralize the entry that causes a + rejection. `session/read` already lists active context with entry + IDs, so the operator can find that entry. +5. A repair that invalidates preserved thinking uses the provider's supported + continuation policy, so incompatible past reasoning does not itself prevent + the session from continuing. + +## Rationale: repair active context to preserve task continuity + +Active context is a repairable projection of the session's durable history. +Compaction is one existing repair strategy: when context grows too large, it +summarizes older material so the task can continue. Media normalization, +request-time omission, and operator redaction address other reasons the +provider can no longer use the context. They share the same objective: +preserve the work already done and restore a usable conversation. + +The choice of remedy depends on how confidently the runtime can identify the +problem. A known context or media limit permits an automatic repair. An +unexplained rejection calls for a visible failure and a precise operator +repair mechanism. The runtime does not choose entries to redact on a guess. + +A repair preserves task continuity, but cannot promise identical reasoning +continuity. Compaction loses detail; omission hides older media; redaction +neutralizes selected content. If a repair invalidates provider-bound thinking, +the provider may also need to discard that reasoning. Losing it can require +the model to reconstruct conclusions or repeat analysis, but does not require +discarding the rest of the conversation or starting a new session. + +Durable context repairs use revision guards, safe execution boundaries, and +ordinary audit events. Request-time transformations leave stored entries and +original blobs intact. Compaction and redaction retain their own policies and +implementations; this proposal does not introduce a generic repair framework. + +## Incident + +A long-running agent session accumulated 32 images through tool results, +one of them 2166 × 2464 px. Each image passed admission when it was produced. +Once a request carried more than 20 images, Anthropic applied its many-image +rule (every image at most 2000 px per side) and rejected the whole request +with `invalid_request_error`. Every later run resent the same history and +failed the same way, including the user's request to make the images smaller. +Recovery required restoring the session from a backup and rewriting its event +log by hand, because no public command could reach the offending entry. + +The cause was specific to one provider, but the failure mode is not: any +provider can reject a history that grew past one of its limits or that holds +one entry it no longer accepts, and the runtime has no supported way out. + +## Baseline + +- [Tool result media](p171-tool-result-media.md) assumes providers downscale + oversized images themselves and states that request failures are + forbidden. The first part is true only per image: the many-image rule + rejects rather than downscales, and it counts images from earlier turns. +- Admission (`engine::media::admit_tool_media`, gateway run input) checks media + type, a 10 MB raw byte limit, and at most eight items per result or run. + Dimensions, image counts across the session, and request totals are never + checked. +- All three adapters read the original blob and base64-encode it on every + request (`llm-runtime` `blob_io::read_base64`). The 10 MB raw admission + limit therefore admits images over Anthropic's 10 MB *encoded* limit, and a + few dozen ordinary images exceed the 32 MB request limit. +- Compaction requests lower the same entries, images included, so compaction + fails on the same history. +- Provider errors are classified provider-neutrally (`ProviderFailureKind` in + `llm-clients`), but `LlmRuntime` passes on only the retry decision. Every + terminal provider error becomes an untyped message, and the run fails as a + generic `ModelFailure`. +- Context ordering is entry-ID ordering: active entries keep strictly + increasing `entry_id`, and a keyed upsert removes the old entry and appends + its replacement at the tail. External context commands (`UpsertContext`, + `ReplaceContextPrefix`, `RemoveContext`) address entries only by key. + Run-appended entries have no key and are unreachable. A keyed replace also + moves the entry to the tail. `session/read` returns the active context + (`activeContext`) with entry IDs, kinds, and previews. +- Tool calls and tool results are separate entries (`ToolCall`, `ToolResult`), + one per call. Tool-produced media are further separate user-role entries + that follow the result. +- Every provider requires each tool call to be answered: Anthropic a + `tool_result` per `tool_use`, OpenAI Responses a `function_call_output` per + `function_call`, Chat Completions a `tool` message per `tool_calls` id. + Removing calls is not safe either: an OpenAI Responses reasoning item must be + followed by the item it produced, and Anthropic signs thinking across the + assistant turn that holds the calls. + +### Provider limits + +These limits set the values of the media budget (Decision 2), which sits +below the limits of every supported API kind. They are not consulted at +request time. + +Anthropic Messages, first-party API, as of 2026-10-01: + +| Limit | Value | +| --- | --- | +| Per image, any request | 8000 × 8000 px | +| Per image, request with more than 20 image blocks | 2000 px per side; earlier turns and `tool_result` images count | +| Images per request | 600 (100 for 200k-context models) | +| Per image, base64-encoded | 10 MB | +| Request body | 32 MB | +| Native resolution, high-resolution tier (Claude 4.7 and later) | 2576 px long edge, 4784 visual tokens; larger images are downscaled server-side | + +OpenAI Responses and Chat Completions limits are checked against current +provider documentation during implementation, to confirm that the budget +sits below them too. + +## Decisions + +### 1. Normalize every image once, with a fixed cap + +The adapter sends a normalized copy for the model instead of the original +bytes. This is a property of lowering, not of admission or session state: +the stored blob, the entry's `ContentRef`, its `media:` handle, and every +projection keep referring to the original. A session may change models within +its provider, so a copy computed for one request shape must not be baked into +durable state. + +- **The cap is fixed and independent of the request.** No side may exceed + 2000 px. A cap that depended on the request (for example, 2576 px until the + 21st image) would change the bytes of earlier images partway through a + session, which invalidates the prompt cache and edits history as the + provider sees it. With a fixed cap, an image is lowered identically from its + first request to its last. On high-resolution models this gives up at most + the 2000–2576 px range, which the provider would otherwise downscale itself. +- **A byte budget per image.** If a resized image is still above the + per-image budget (initially 3.75 MB raw, which is 5 MB encoded), it is + re-encoded as JPEG at a fixed quality, with any alpha channel flattened + onto white. +- **Compliant images pass through byte-identical.** Dimensions come from the + image header without a full decode. An image within both the pixel cap and + the byte budget is sent unchanged, so existing sessions without oversized + images see no prompt-cache change. +- **Output is deterministic.** For a given source and normalization spec, the + output bytes are always the same: fixed resampling filter, fixed encoder + settings, pinned codec crate version. Caching is therefore only an + optimization. A worker-local LRU keyed by (source blob ref, spec version) + avoids repeated decodes; a cache miss on another worker yields the same + bytes. A persistent copy store is added only if measurement calls for it. +- **A resized image states what the model sees.** Its announcement gains the + dimensions the model sees beside the original's, for example + `· shown at 2000×1400 of 4000×2800`, so coordinate-based work can scale + back to the source. The text is deterministic and does not affect caching. +- **GIF and animated images** lower their first frame, which matches what + providers read. +- **PDFs are not normalized.** They count toward request totals in Decision 2. +- One shared function in `llm-runtime` serves all three adapters and the + compaction request path, which shares lowering. The engine is unchanged. + +Normalizing an existing history can change image bytes the provider has +already seen. This migration uses the thinking-continuation policy in Decision +5, just as omission and redaction do. + +### 2. Keep each request within one fixed media budget + +After normalization, lowering counts the media in the request against one +media budget: a maximum number of media items and a maximum of encoded media +bytes. The budget is a constant, the same for every provider and model, and +conservative enough to sit below every supported API kind's limits: at most +100 media items (Anthropic's per-request cap on 200k-context models) and +24 MiB of encoded media (room for text below Anthropic's 32 MB body limit). +Omission is counted in chunks of 10, and rounding never drops below the four +newest items that fit. + +- **One budget, not a limits table per provider.** A table per API kind would + have to track provider limits by hand, and a stale row would either omit + media needlessly or miss a real limit. It would also move the cut point + whenever a session switches model or API kind, invalidating the prompt cache + and preserved thinking, which is the instability Decision 1's fixed pixel + cap avoids. After normalization, every image already meets the per-image + limits, so the budget only has to bound the aggregate. +- **When it fits, nothing changes.** +- **When it does not fit, the oldest media is omitted.** Media entries are + replaced, oldest first, with the placeholder text the text-only path already + uses: + `[image · media:3f9a2c1d4e7b · omitted from this request to stay within provider limits]`. + Order is by recency alone. The latest tool batch is the newest media, so it + is omitted last without any special protection. If it alone exceeds the + budget, its newest items are kept: eight images at the 5 MB encoded + per-image budget already exceed a 32 MB body limit. Failing the turn instead + would not help, because the latest batch stays the latest after the run + fails and every later request would fail the same way. +- **The cut point moves in fixed chunks.** The number of omitted items is + rounded up to a fixed chunk size. The cut point is therefore a pure function + of the context, with no stored state: retries produce identical requests, + and the boundary moves only once per chunk of new media, so a growing + session invalidates its prompt cache rarely rather than every turn. +- **The budget never fails a request.** It manages media only, and a single + image always fits within the per-image budget. A request whose non-media + content alone exceeds the provider's body limit is a context-size problem + for compaction, or a rejection under Decision 3. + +Omission rewrites earlier user content as the provider sees it, in sessions +that are still healthy. Decision 1 keeps it rare, because pixel limits no +longer trigger it; only aggregate media does. + +### 3. Report provider rejections as `RequestRejected` + +A terminal provider error classified as `InvalidRequest` or `ContextLength` +fails the run with a new `RunFailureKind::RequestRejected`. Every other terminal +provider error stays `ModelFailure`. + +- The classification comes from the existing provider-neutral + `ProviderFailureKind`. The LLM I/O boundary gains a rejected outcome beside + `Failed`, the turn failure records it, and the run failure carries it. The + engine stays deterministic: it records the classification it is given and + never inspects provider errors. +- The failure record keeps the provider's message word for word. +- A provider-reported `ContextLength` is a rejection like any other: it does + not trigger compaction. Compaction keeps its own token-budget policy, and + the operator can run `session/context/compact` after seeing the failure. +- On a rejection, the adapter logs, next to the provider's message, the + position each entry ID was lowered to in the request (for example message + and content index). Provider messages cite request positions, not entry + IDs, and only the adapter knows how entries were merged into provider + messages. The mapping is a log line, not durable state: its shape is + provider-specific. +- Clients show that the provider rejected the request, with that message. + They do not suggest a fix or guess which entry caused it: the runtime cannot + know, and provider messages differ in how precisely they point at a cause. +- The public run failure view gains the new kind; the API contract and the + TypeScript consumers are regenerated. + +### 4. Replace context entries in place + +`session/context/replace { sessionId, entries: [{ entryId, item }] }` replaces +active entries by entry ID. Its shape follows `session/context/append`: each +entry carries an `InputItem` converted by the same path, and results report +`replaced`, `unchanged`, `absent`, or `failed` with an admission failure per +entry. It mirrors `ReplaceContextPrefix` with entry IDs instead of a key +prefix, reusing the existing structures: a +`ReplaceContextEntries { expected_revision, entries }` command of +`ContextEntryInput`s and an `EntriesReplaced { base_revision, entries }` event +of `ContextEntry`s, projected as `contextEntriesReplaced` with entry views. + +**In place, not removal.** A replaced entry keeps its entry ID, position, key, +source, and kind, including role and `call_id`. Removing a tool result would +leave its call unanswered, which every provider rejects; removing the call as +well breaks reasoning and thinking that providers bind to it. Replacing under +the same entry ID keeps both the ordering invariant and call/result pairing. +A keyed upsert cannot do this, because it appends a new entry at the tail, +and run-appended entries have no key. Pairing alone does not preserve +thinking bound to the earlier content; Decision 5 supplies the continuation +policy after that content changes. + +**The engine guards kind, not content.** A replacement must keep the entry's +kind, key, and source, and only tool results and user messages qualify: tool +calls, assistant output, reasoning, and provider-opaque entries carry content +the provider signed or shaped. A tool result takes only text; a user message +takes text or media, so an image can also be replaced by a smaller copy. +Adapters lower the new content like any other tool result or user message, +and an image replaced by text is no longer media anywhere. + +A kind that cannot be replaced, or media for a tool result, fails that entry; +other entries in the request still apply. A run in progress or a closed +session rejects the whole request, and the engine also refuses while +compaction is pending or for unconsumed run input or steering. An ID no +longer in active context reports `absent`, and an identical replacement +reports `unchanged`, so retries are idempotent. The engine command is atomic: +a refusal by the workflow fails every entry it carried. + +**Redaction is a client convention.** The CLI's `session context redact` +replaces entries with standard placeholders: + +| Entry | Placeholder | +| --- | --- | +| Tool result | `[tool result removed by operator]` | +| Media (image or document) | `[image · media:3f9a2c1d4e7b · removed by operator]` | +| User message (run input, steering, context edit) | `[message removed by operator]` | + +The original content stays in the event log. The web transcript resolves +`media:` handles from transcript history, so a replaced image still renders +there. A sub-agent hand-off resolves links against the child's active +context, so a replaced image no longer travels with it. There is no web +affordance and no automatic redaction. + +**Finding the entry.** `session/read` returns the active context in context +order, with each entry's ID, kind, preview, and media handle; the CLI lists +it as a table (`lightspeed session context list`). Together with the +adapter's position log from Decision 3, an operator can go from a provider +message that cites a request position to the entry ID to replace. + +### 5. Continue after a repair invalidates preserved thinking + +Thinking compatibility is part of recovery for normalization of existing +histories, omission, redaction, and compaction that retains thinking from +earlier turns. It is an implementation requirement, not an optional check on +sessions that are still healthy. + +The Anthropic adapter defaults to +`thinking.block_binding.prefix_mismatch_behavior: "drop_block"` wherever the +model and thinking mode support it, with the +`thinking-binding-controls-2026-08-01` beta header. Anthropic then drops +incompatible thinking and subsequent thinking blocks while retaining the +other request content. This policy remains on subsequent requests and after +restart; it is not a one-request retry setting. See the provider's +[preserved-thinking contract](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking). + +Setting the field also changes behavior on accounts the provider does not +enforce by default (created before 2026-08-31): any value opts the request into +enforcement, so mismatched thinking that such accounts currently pass to the +model is dropped instead. This is the intended contract, and it makes every +deployment behave the same. + +The adapter continues sending the stored thinking unchanged. Original +reasoning stays in the event history. New responses may still generate +thinking. Other request errors continue through Decision 3; this policy does +not make every provider rejection recoverable. + +`drop_block` also absorbs history edits the runtime makes by mistake, which +would otherwise surface as rejections. Two measures keep such bugs visible: + +- Production logs every reported `input_transformations` entry with its path + and reason, so unexpected drops are observable. A per-session metric is + added only if the logs prove insufficient. +- Live and CI suites that do not exercise a repair send `"error"`, so an + unintended history edit fails a test instead of being absorbed. + +Anthropic accepts `block_binding` only with `adaptive` and `enabled` thinking. +Thinking that is off needs no fallback: every model that checks preserved +thinking (Claude Fable 5.1, Claude Opus 5.5, and Claude Sonnet 5.5) rejects +`disabled` outright. Reasoning effort `none` therefore lowers by model: to +`disabled` where the model accepts it, to `between_tools` on Claude Sonnet +5.5, and to adaptive thinking at the lowest effort where thinking cannot be +turned off (Claude Opus 5.5, the Fable and Mythos lines). Requests without a +thinking config on a model that thinks by default carry no binding and keep +the provider's account default; compaction requests, which replay earlier +thinking, send an explicit adaptive config on those models so the policy +applies to them too. Other adapters follow their native contracts; +Anthropic's policy does not authorize stripping OpenAI reasoning items or +other provider-opaque content. OpenAI Responses accepts replayed encrypted +reasoning after an earlier image changes, so it needs no equivalent. + +Provider wire settings, their interpretation, and dropped-block diagnostics +remain in the adapter. This decision does not change the engine or the +public contract, and nothing inspects signatures. Stable normalization and +chunked omission still matter: fewer history edits preserve more reasoning +and more of the prompt cache. + +## How a failing session recovers + +| Failure | Handled by | Automatic | +| --- | --- | --- | +| Context exceeds its token budget | Existing compaction policy: older context summarized | According to session policy | +| Image over a provider's pixel or per-image byte limit | Normalization (Decision 1): a bounded copy is sent | Yes | +| Request over the media count or byte budget | Media budget (Decision 2): oldest media omitted in fixed chunks | Yes | +| Unexplained rejection caused by a redactable entry | `RequestRejected` (Decision 3), then redaction by an operator (Decision 4) | No | +| A repair invalidates preserved thinking | Provider-specific continuation (Decision 5): incompatible past thinking excluded from model input | For verified model and mode combinations | + +The runtime repairs automatically only what it can predict. For anything +else it cannot know which entry is at fault, and removing context on a guess +is worse than a visible failure. The provider's message, shown word for word, +is the operator's starting point. +Redaction is a repair mechanism for selected entries, not a guarantee that +every rejection is caused by content it can repair. + +## Slices + +1. **Normalization and thinking continuation.** Shared lowering function in + `llm-runtime`, header probe, fixed cap, byte budget, deterministic + encoding, resize announcement, worker-local cache, all three adapters. + Anthropic `drop_block` default, beta header, `input_transformations` + logging, `"error"` in suites that do not exercise a repair, and + model-specific lowering of effort `none`. Tests: oversized PNG and JPEG are downscaled + within the cap; compliant images pass through byte-identical; output is + identical across calls; a 32-image history with a 2166 × 2464 image lowers + within the many-image rule; unchanged histories retain valid thinking; an + existing history whose image is newly normalized continues with prefix + enforcement enabled, across later turns and a restart, with original + history unchanged; compaction that retains thinking continues likewise. A + credentialed live suite exercises an enforcing model and mode explicitly, + rather than relying on the account age or the default model. +2. **Rejection.** `RequestRejected` through the I/O boundary, turn, and run + failure; the adapter's position log; contract regeneration. Tests: an + `InvalidRequest` and a `ContextLength` error fail the run as + `RequestRejected` with the provider message intact; other terminal errors + stay `ModelFailure`. +3. **Replacement.** The entry-replacement command and event, + `session/context/replace`, CLI `context list`, `replace`, and `redact`, + contract regeneration, and replay coverage for replacement and its + rejections. + Tests: a redacted history continues with prefix enforcement enabled, and a + session whose request the provider rejects runs again after redaction. +4. **Media budget.** The budget constants, oldest-first omission rounded to a + fixed chunk, in all three adapters and the compaction request path. Tests: + omission order; an eight-image result over the budget keeps its newest + images, and the next request is identical; identical requests across + retries; the cut point holds steady until a chunk of new media arrives; a + history with omitted media continues with prefix enforcement enabled. + +Slice 1 closes the incident: normalization removes the per-image failure, and +`drop_block` lets existing sessions continue once normalization changes image +bytes the provider has already seen. Every later slice can also change such +content, so each verifies continuation for its own repair. Slice 3 supplies +operator repair for unexplained rejections caused by redactable entries. +Slice 4 comes last because, after normalization, only aggregate media can +trigger it. + +### Progress + +Slice 1 is implemented: `llm-runtime::media` normalizes images for all three +adapters, and the Anthropic adapter sends the binding policy, configurable on +the hosted runtime through `LIGHTSPEED_ANTHROPIC_THINKING_PREFIX_MISMATCH`. +Live suites cover an oversized image on every adapter, and on Claude Opus 5.5 +an unchanged replay verifying under `error`, an edited image failing generation +and compaction under `error`, and both continuing under `drop_block` with the +dropped thinking reported. Restart continuity is not separately tested: the +policy and normalization are pure functions of configuration and stored +content, so a restarted worker sends the same request. + +Slice 2 is implemented: the I/O boundary carries `CoreAgentIoError::Rejected` +and `LlmGenerationStatus::Rejected`, the turn records `TurnOutcome::Rejected`, +and the run fails as `request_rejected` with the provider's message as its +failure text. The web transcript and the CLI say that the provider rejected +the request. Each adapter logs, on a rejection, which entries each message or +input item holds (`messages.3=[12,13]`). A hosted live test sends an image the +provider cannot decode and checks the kind and the unwrapped provider message. +Only HTTP rejections are classified: an OpenAI Responses response that reports +`status: failed` in-band, and a rejected compaction request, still fail as +before. + +Slice 3 is implemented as entry replacement (Decision 4). The hosted live +test continues past the rejection: it replaces the undecodable image with a +placeholder through `session/context/replace`, checks that the entry keeps +its id and is no longer media, and runs the same session again successfully. + +Slice 4 is implemented: `RequestMedia` prepares every image and PDF of a +request once, decides which oldest items to omit, and hands the prepared +copies to the adapter, so the budget costs no extra blob reads; compaction +requests go through the same lowering. Unit tests cover omission order, +whole-chunk steps, an oversized batch keeping its newest items, and +identical requests across calls. A live test on Claude Opus 5.5 crosses the +budget after a thinking turn: the strict policy rejects the rewritten +history, and `drop_block` continues with the right answer. + +## Non-goals + +- Changing compaction triggers or summarization strategy.

One deterministic scheduling and recovery lifecycle +serves every route; adapters preserve each provider's native continuation rules. + +Provider-triggered compaction remains a fully supported, first-class explicit +mode, especially for OpenAI Responses where provider-managed triggering is a +preferred operating choice. It runs inside ordinary generations and keeps its +native capture, pruning, usage, and continuation behavior. Engine-managed +standalone defaults do not replace or weaken this path. + +An enabled session can recover from a context-length failure even when no +threshold was supplied. Recovery preserves recent work, compacts older material +through bounded requests, and resumes the same run without repeating completed +tool side effects. Explicitly disabling compaction disables both proactive +compaction and automatic context-length recovery. + +An explicit `session/context/compact` call remains available in every mode, +including Disabled. It selects the native standalone operation when supported, +otherwise the Lightspeed summarizer.

A compatible +API shape or a recent model name does not establish native compaction support. +If native standalone compaction is unavailable, Engine default uses the +Lightspeed standalone path. An explicitly requested unsupported +ProviderTriggered mode fails validation instead of silently becoming another mode. + +ProviderTriggered and engine-managed standalone are separate automatic +strategies. Do not proactively schedule standalone work over a healthy native +triggered generation. Its standalone path is used for explicit API compaction +and context-length recovery, with provider-specific strategy transitions only +where required. Full native triggered support is part of the first version. + +Keep provider identity and API kind pinned. Fallback does not select another +provider, endpoint, credential, or model. Use the effective generation model +for the operation and validate model overrides against retained native state. +Switching models within a pinned route must not silently drop opaque state or +invalidate signed thinking. + +The current ProviderStandalone name already covers summary generation for +Chat Completions. Keep compatibility with existing clients; exact DTO naming +and any added effective-policy projection are implementation decisions. + +## Defaults and thresholds + +### Provider-triggered + +No user threshold means use the supported provider default, while still sending +the configuration that enables compaction. Compaction is not enabled merely by +omitting its settings from an ordinary request. + +- OpenAI Responses uses `context_management` with a compaction edit. Retain the + existing optional-threshold lowering and verify absent-threshold behavior + against supported models as part of full mode support. Do not infer a numeric + OpenAI default from Anthropic's value. If a route requires a threshold, the + adapter supplies a verified model-aware default without requiring user input. +- Anthropic Messages uses `compact_20260112` in `context_management.edits` and + the `compact-2026-01-12` beta. Its documented default is 150,000 input tokens; + explicit triggers must be at least 50,000 tokens. +- Explicit thresholds must satisfy both provider validation and the selected + model's usable input budget. Reject an unusable override instead of enabling + a trigger that cannot run before the request exceeds the window. + +Provider-native request fields and beta headers belong to adapters. Reject +conflicting raw provider parameters rather than allowing them to bypass the +configured policy, especially Disabled. + +### Standalone + +With known limits, no user threshold means an engine-managed proactive +threshold, not manual-only behavior. A supplied threshold overrides that +proactive threshold; overflow recovery remains enabled in either case. + +Compute the usable input budget from the model's context window, output and +reasoning reservation, request overhead, and safety margin. Count current +instructions, tools, media, and retained native state as well as conversation +text. Avoid using cumulative billed usage as the current window size; cache +usage and compaction iterations need provider-specific interpretation. + +Evaluate pressure before generation at safe turn boundaries, including between +tool rounds within a long run. Idle maintenance remains useful but cannot be +the only trigger. Large new input can require compaction before its first +generation. Protect that input rather than immediately summarizing it away. + +Resolve numeric capacity outside the engine for the effective model and route: +explicit model/endpoint limit override, provider-reported limits, then verified +limits for supported model versions. Preserve the distinction between a +separate input limit and a total window shared with output; do not subtract +output twice. Record the resolved limits and their source as deterministic +facts. Resolve a model override independently. Do not make replay read mutable +discovery metadata or introduce an extensive model-catalog subsystem. + +Occupancy describes the next rendered request. Use previous provider usage as +a baseline, account for newly added content and changed instructions/tools, +and obtain more accurate adapter counts where available and necessary. The +engine compares recorded capacity and occupancy; it performs no tokenizer or +provider I/O. Missing per-entry estimates must not disable recovery. + +For unknown limits without an explicit threshold, let the session run until a +typed context-length failure and recover through standalone compaction. Do not +require a guessed limit to admit the provider. After successful recovery, +observed request sizes may support a conservative session-specific proactive +trigger, clearly marked as inferred rather than an exact discovered limit. +That inference is optional tuning; error-driven recovery is required in v1. +The initial threshold fraction, safety margin, summary budget, and recent-tail +budget need explicit implementation defaults and tests; this proposal does not +claim measured optimal values. + +Treat `target_tokens` as a supported hint or summary budget, not a guaranteed +native output size. Check whether the resulting next request actually fits. + +## Native standalone operations + +### OpenAI Responses + +Use `POST /responses/compact`. The request must fit the selected model's context +window, so an already oversized history requires bounded input preparation. + +Preserve the complete returned compacted window, including retained messages +and other items alongside the encrypted compaction item. Do not filter it down +to only compaction items or apply the ordinary provider-triggered prune rule +to items the endpoint deliberately retained. Record which submitted prefix +the result replaces; a tail omitted from that request follows its result. +Continue to supply current Lightspeed-owned instructions and catalogs according +to native request semantics. + +The encrypted item is provider state, not text to feed to the Lightspeed +summarizer. Prefer native re-compaction for windows carrying it. A lower-fidelity +fallback can use retained source history where available, but must report +failure if it cannot preserve the required state within its budget. + +### Anthropic Messages + +Use the ordinary Messages endpoint with top-level +`compaction: {"type": "summarize"}` and the `compact-2026-09-04` beta. This +is a native on-demand operation, not a separate compaction URL or an appended +user summarization instruction. + +Send the matching system prompt and tools. Strip generation-only parameters +that the operation rejects. Validate the stop reason and a usable returned +block; a successful HTTP response alone does not establish successful +compaction. Preserve the block's content, signature, and native fields exactly. +Send the beta on subsequent requests carrying the block. Replace the submitted +messages and place the signed block first, followed by the untouched recent +tail. Respect the provider's conditions for retaining thinking. + +**Threshold compaction cannot run on a request carrying an on-demand signed +block.** Manual native compaction or native overflow recovery in a +ProviderTriggered session therefore changes its effective execution strategy: +while that block is active, use engine-triggered native standalone compaction +and omit the threshold edit from subsequent generations. Keep the requested +configuration unchanged and record the transition as a provider-neutral fact. +Expose the effective strategy and reason to clients. The same restriction +applies when a user enables ProviderTriggered after an earlier manual compact. + +After a manual compact in Disabled, replay the block correctly but perform no +later automatic compaction. The mode transition must never override Disabled. + +Validate interoperability with earlier threshold blocks and model overrides +through adapter and live tests. Do not treat the old and new blocks as +interchangeable simply because both use native type `compaction`. + +### Chat Completions and native-operation fallback + +Use a dedicated summary call on the selected route, without tools or task +execution. Preserve goals, constraints, decisions, identifiers, unique findings, +unfinished work, and references needed to retrieve details. Record the result +as Lightspeed semantic context, distinct from native opaque state. + +Lower roles, token budgets, and reasoning parameters according to the provider. +DeepSeek's system role and token fields must not inherit OpenAI-specific +assumptions merely because both use Chat Completions. + +Use this operation when a native standalone capability is unavailable or a +bounded native attempt cannot fit. Authentication errors, rate limits, generic +invalid requests, and refusals must not be reclassified as context pressure. +Do not retry refusals through alternative prompts as overflow recovery. + +## Selecting and reducing context + +The first version uses protected-tail, chunked compaction for proactive, +manual, and error-driven standalone operations. Automatic tool-result clearing +is deferred: it introduces another information-loss policy and is not needed +to establish the shared lifecycle. + +Runs are not retention units or compaction boundaries. A run may last hours, +contain many model/tool exchanges, and compact repeatedly before completing. +Every compaction operates on the current context revision at a safe generation +boundary without ending or restarting the active run. + +All standalone operations share a deterministic selection plan: + +1. Preserve current canonical instructions and catalogs independently of the + summary. Protect unconsumed run input, steering, pending tool interactions, + and the current task's recent complete exchanges. +2. Select a recent tail using complete model/tool exchanges and a token budget, + never a count of runs. A user turn can include many exchanges; retaining + the entire current run or user turn would leave hours of work uncompactable. + Keep a tool call and all its answers on the same side of a cut, with stricter + recorded request boundaries where provider thinking bindings require them. + Never silently truncate protected new input to make room. Preserve this + tail from the first attempt, not only after another strategy fails. +3. Divide the older prefix into bounded, coherent chunks at provider-valid + generation/tool boundaries. A prefix that fits may be one chunk. For unknown + capacity, reduce a rejected chunk at those boundaries and retry within the + operation budget. The original generation overflowing and a compaction + request overflowing are distinct observations with different next steps. +4. Build a rolling compacted prefix: compact the first chunk, then compact its + result with the next chunk, until the selected prefix is covered. Include + any previous session compaction state in that prefix. Each adapter must + support and test this accumulation using its native continuation rules. + Do not concatenate independent signed/encrypted artifacts or feed opaque + native state to a text summarizer. Stage results without pruning source + entries; finish with one valid compacted prefix or native compacted window. +5. Assemble canonical context, compacted prefix, recent tail, and current input + using each adapter's native ordering rules. Validate the resulting request + with sufficient headroom before committing and resuming generation. + +Native summaries must preserve provider continuation rules. Client-side +history changes can invalidate Anthropic thinking bound to earlier content; +prefer native on-demand summaries where they preserve the kept thinking. When +a supported repair requires discarding incompatible thinking, record that +loss and apply the established continuation policy in the adapter. Never +rewrite signatures, opaque reasoning, or assistant tool-call records in place. + +If the smallest provider-valid chunk cannot fit, or a rolling native artifact +cannot be combined with the next chunk within the budget, return a clear +failure. Do not silently remove tool evidence to force success. Supporting +oversized individual entries through further content splitting is separate +adapter work, subject to the same information-preservation and budget rules. + +## Context-length recovery lifecycle + +Recovery starts only from a normalized context-length rejection or equivalent +provider context-limit finish. Preserve that typed fact across the client, +runtime, worker, turn, and run boundaries. Ordinary request rejections retain +their existing visible failure behavior. + +```text +generation reaches a context limit + -> record the normalized failure and pause generation for the same run + -> check effective policy; Disabled ends with the context-limit failure + -> freeze the context revision and protected entries + -> select an older prefix and protect recent complete model/tool exchanges + -> compact the prefix through bounded rolling native or Lightspeed requests + -> validate and atomically commit the replacement and any strategy transition + -> retry generation with the same run and already-recorded tool results +``` + +Use explicit per-recovery attempt, summarization-call, token/cost, and elapsed +budgets. Require measurable reduction in the next rendered request; reject +empty, truncated, invalid, or non-progressing results. Transport retries remain +separate from the engine's context-recovery budget. Budget exhaustion produces +a clear terminal failure instead of another identical generation loop. + +If canonical context and protected input alone exceed the usable window, +automatic compaction cannot solve it. Report that condition without deleting +the protected content. Cancellation and run deadlines remain effective while +recovery is executing. + +Only one context mutation may commit at a time. Guard results with the base +revision and recorded covered range; stale results must not erase new input or +steering. An activity retry or workflow replay must not apply a result twice. +Intermediate chunk summaries do not prune source entries. Commit a validated +replacement atomically after all required stages succeed; otherwise leave the +previous active context available for inspection and repair. + +## Manual API, projections, and compatibility + +`session/context/compact` means perform one standalone operation, independently +of automatic policy. Disabled therefore suppresses automatic compaction only. +It does not remove native artifacts already needed for continuation, and an +explicit compact does not enable future automatic compaction. + +Admit manual requests at a safe boundary. If work is active, queue the operation +until the current generation and pending tool batch have settled; do not mutate +their frozen context. Preserve existing API admission/result conventions and +make duplicate pending requests explicit. Start from the context revision at +execution, or reject a caller-supplied stale expected revision. Define queued +manual ordering relative to later run requests so compaction cannot starve. + +Expose requested mode, effective strategy, effective threshold and its source, +trigger (manual, proactive, or context-limit recovery), progress, and failure. +Show before/after estimates where available, attempt counts, chunk progress, +and any thinking loss. Clients need readable compaction markers, +not signed or encrypted payload dumps. Retain usage for standalone calls and +native compaction iterations without double-counting generation usage. + +Changing omission from Disabled to Engine default is a behavior change for +existing sessions and profiles. Lightspeed is early with few users: prefer a +deliberate, focused configuration upgrade over extensive compatibility +machinery. Preserve historical replay semantics and existing session history; +changing the default does not authorize rewriting prior events. New +session/default resolution follows the established explicit configuration, +profile, and inheritance rules. Record effective capabilities and policy facts +at deterministic boundaries; replay must not consult today's model catalog. +Do not silently reinterpret old omitted settings as permission for new paid +summary calls. Explicit Disabled remains authoritative in every version. + +## Implementation progress + +The engine now resolves omitted policies to standalone on new session and +configuration admissions. Historical omitted policies keep their original +Disabled replay behavior; replacing configuration opts that session into the +new resolution. Explicit Disabled remains unchanged. No historical events are +rewritten. + +The shared standalone lifecycle runs between generations, including multiple +operations within one run. It freezes the covered prefix and revision, replaces +that prefix atomically on success, and keeps the two newest settled generation +exchanges and their immediately preceding user input where older history exists. +With no older prefix, explicit compaction can cover the settled window. A second +consecutive context-length failure expands coverage to the whole settled window; +unconsumed current input and unanswered tool exchanges cannot be discarded. +Recovery allows two attempts per consecutive overflow sequence, resets after a +successful generation or a new run, and preserves the exact terminal provider +error when its budget is exhausted. Partial rejected generation output is not +committed or executed. Manual requests queue without moving an in-flight +request's revision; cancellation can abandon a pending compaction. + +The runtime rolls bounded complete chunks into one replacement window. Defaults +are 32 calls, 2,000,000 cumulative input tokens, and a 600-second operation +deadline. Typed context-length rejection shrinks a chunk at a safe boundary; +ordinary invalid requests, authentication failures, and refusals abort. A +smallest atomic exchange that cannot fit fails clearly and leaves source context +intact. Previous native compacted windows remain indivisible. Tool-result +clearing, chunk telemetry events, and learned thresholds are deferred. + +Capacity is resolved outside the reducer and recorded separately from the +user's optional `context.inputLimitTokens` override. Anthropic model discovery +supplies reported input capacity. OpenAI and custom routes whose discovery does +not supply it remain unknown; they use error-driven recovery unless an override +is supplied. The default proactive threshold is 80% of known usable input +capacity. Run overrides use their own resolved capacity, and never inherit a +limit from a different model. Retained signed, encrypted, or reasoning state +prevents incompatible model changes. + +OpenAI standalone retains every item in the returned window, in order. Supported +Anthropic models use native on-demand compaction, retain its exact signed block, +and select the on-demand beta on replay. A retained signed standalone artifact +suppresses Anthropic threshold compaction while preserving the requested policy. +Older Messages models and all Chat Completions routes use ordinary summary +generations. Explicitly unavailable native endpoints (unsupported operation or +HTTP 404/405/501) fall back to a summary call on the same route. Generic HTTP 400 +errors do not authorize a fallback. Native requests retain current tool/catalog +configuration, and Anthropic provider-hosted MCP auth is resolved at send time. + +API projections expose requested/effective mode, strategy, threshold/source, +capacity, observed token usage when current, pending/queued state, recovery +attempts, and finished-call usage/counts. Session settings show effective mode, +threshold source, pending/queued status, attempts, and the Anthropic transition. +Public contracts and TypeScript consumers have been regenerated. Fine-grained +per-chunk progress and provider-reported thinking-loss telemetry remain follow-up +observability work; the engine never rewrites the preserved tail's raw entries. + +## Architecture and implementation sequence + +The deterministic engine owns policy facts, protected ranges, safe boundaries, +recovery budgets, revision guards, and context events. It emits intents for +counting and compaction where effectful work is required. Capability discovery, +tokenizers, provider calls, native JSON, beta headers, CAS reads/writes, and +transport configuration stay in effectful adapters and activities.

Compaction uses +Idle, QueuedManual, or Pending with a required frozen plan; requests also require +that plan, without an older planless-request compatibility path. Model and input +capacity remain available after a run ends, while token observations are usable +only at their recorded context revision. Recovery attempts and the recovered +turn belong to the active run, so a subsequent run starts with a fresh budget. +Queued and pending snapshot restoration, observation replay and invalidation, +and a new run after exhausted recovery are covered by deterministic checks. + +The frontend transcript retains original conversation history while suppressing +standalone replacement entries, including native messages, tool copies, and +text summaries. A single operation marker progresses through queued, compacting, +and succeeded or failed states; provider-triggered compaction retains its native +marker. Run statistics include reported standalone usage and call counts while +keeping the last generation's context measurement separate. Older-page loading +preserves a live marker's identity and recovers its run attribution without +replaying old lifecycle events into live controls. Session closure interrupts +unfinished progress. Validation on 2026-10-02 passed all 688 frontend tests, +TypeScript checking, and the production frontend build. + +Two seeded demo conversations now exercise the transcript and settings on +2026-10-02. Software Factory's LIN-1421 implementation thread uses Engine +default standalone with a 10,000-token input override and the derived 8,000-token +threshold. It compacts inside one run before opening the PR, keeps the last two +completed tool exchanges unchanged, and includes the compaction call in run +usage. Personal Assistant's Ada Telegram thread uses provider-triggered +compaction with an explicit 50,000-token threshold; its native artifact appears +inside an ordinary generation and later work retains the promised cohort cut, +references, and send-approval requirement. Both examples use Opus 5.5 and keep +the original transcript history. Demo policy edits refresh the settings +projection. These are simulated provider artifacts, not additional live-provider +evidence. All 691 frontend tests, TypeScript checking, and the demo build passed. + +## Implementation validation + +State-refactor checks on 2026-10-02 passed: 788 scoped library tests across the +engine, API projection, workflow, hosted server, and in-process runner; the exact +workspace/all-targets Clippy gate with warnings denied; and all 14 rerun live +cases. The live checks comprise the 12 dedicated OpenAI Responses, Anthropic +Opus 5.5, and OpenAI/DeepSeek Chat Completions compaction tests plus the two +serialized hosted standalone-compaction and continuation tests. + +Completed checks on 2026-10-01: + +- Cross-crate engine, runtime, provider client, API projection, workflow, and + in-process runner tests, including replay, protected tool exchanges, unknown + capacity recovery, partial-output discard, cancellation, manual queueing, + exact full native windows, same-route fallback, and capability selection. +- Hosted runtime library tests: 359 passed, one unrelated credentialed test + ignored.

The hosted cases cover manual compaction in Disabled, proactive +standalone, retained native artifacts, continuation with exact fact recall, and +finished-call usage. They wait for compaction's own completion independently of +run completion. Opus uses 5.5, including the shared live fixture default. + +The rerun corrected older Anthropic fixtures that expected a plain-text summary +and a binding rejection during native whole-window compaction. The updated +checks verify exact signed output and successful strict continuation from the +replacement; strict rejection of edited preserved thinking during ordinary +generation remains covered. Native capability selection also includes the +currently documented Sonnet 5.5, Fable 5.1, and Mythos 5.1 model identifiers. + +Rare overflow and refusal outcomes use deterministic/synthetic fixtures. These +passes do not claim live verification of every compatible custom endpoint or +the complete credentialed Temporal test matrix. Unknown capacity remains deliberately +reactive, and an oversized indivisible exchange fails without silently dropping +history. + +## Validation and acceptance + +Unit and replay tests must cover the full mode/API-kind matrix, explicit +Disabled, default inheritance and legacy configurations, capability changes, +threshold omission/override, model overrides, and raw-parameter conflicts. + +Engine vectors must cover recent-tail and tool-pair invariants; new input larger +than the budget; large single-turn tool runs with multiple compactions before +run completion; rolling-prefix coverage; stale revisions and steering; +successful recovery and bounded failure; cancellation; duplicate results; and +reconstruction of effective strategy transitions from events alone. Completed +tool executions must not be repeated by recovery. + +Adapter tests must cover native request schemas, absent thresholds, exact +signed/opaque replay and repeated native accumulation, full OpenAI compact +output, Anthropic header selection and invalid stop reasons, thinking +continuation, per-iteration usage, and +provider-specific Chat Completions lowering. Native and Lightspeed fallback +paths must both fail clearly when they cannot preserve usable context. + +Integration tests must verify manual compaction in Disabled and +ProviderTriggered, safe active-run scheduling, proactive standalone without a +user threshold when limits are known, error-driven recovery with unknown +limits, HTTP and in-band context-limit recovery, repeated compaction during +one run, and visible final failures. Verify normal provider-triggered operation +does not schedule competing proactive standalone work. Test both in-process +and hosted execution boundaries. Use synthetic +provider fixtures for rare/error outcomes rather than relying on live refusal +or rate-limit behavior. + +Add ignored live tests for OpenAI Responses native trigger/default and +standalone continuation, Anthropic Opus 5.5 native on-demand and its transition +from threshold mode, and OpenAI/DeepSeek Chat Completions bounded summarization +and continuation. Include tool-pair and kept-thinking cases where supported. +Run live tests only when authorized; serialize Temporal suites. Earlier live +passes do not satisfy these new recovery acceptance tests. + +Completion requires scoped Rust and web checks, replay coverage, regenerated +contracts where necessary, and the exact workspace Clippy gate before a PR. +No production rollout should depend on an unverified native compaction default. + +## Evidence and remaining tuning + +Provider documentation reviewed during the design discussion on 2026-10-01: + +- [OpenAI compaction](https://developers.openai.com/api/docs/guides/compaction): + generation-time compaction, standalone input limits, and preserving the full + returned compacted window. +- [Anthropic threshold compaction](https://platform.claude.com/docs/en/build-with-claude/compaction-threshold): + explicit enablement, the 150,000-token default, and the 50,000-token floor. +- [Anthropic on-demand compaction](https://platform.claude.com/docs/en/build-with-claude/compaction-on-demand): + native request, signed-block replay, error handling, supported models, and + incompatibility with threshold compaction. +- [Anthropic keeping recent turns](https://platform.claude.com/docs/en/build-with-claude/compaction-keep-recent-turns) + and [preserved thinking](https://platform.claude.com/docs/en/build-with-claude/compaction-thinking-blocks): + safe cut points, unchanged tails, and thinking-binding conditions. +- [Anthropic context editing](https://platform.claude.com/docs/en/build-with-claude/context-editing): + oldest tool-result clearing with keep/exclude controls and cache tradeoffs. +- [OpenAI session memory examples](https://developers.openai.com/cookbook/examples/agents_sdk/session_memory): + complete-turn trimming and older-history summarization with a recent tail. + +Initial numeric budgets, capacity discovery, native capability selection, and +public projections are recorded in Implementation progress.

Validation recorded below. + +## Outcome + +Injected catalogs describe available resources and how to use them. Live +selection, lifecycle status, discovery diagnostics, and internal identifiers +must not repeatedly append whole menus to model context. + +Existing durable environment IDs and public API identifiers remain valid. +Model-facing environment references become short handles resolved only against +the session's authorized attachments. Full IDs remain accepted. + +## Design + +### Publication and metadata + +Keep immutable catalog text and structured provenance. A keyed catalog upsert +whose title and content are unchanged updates metadata in place through a +recorded context replacement, retaining the entry ID, position, source, and +supersession link. Real text changes retain existing append-and-supersede +behavior. Replay must reconstruct both paths exactly. This keeps skill API +warnings and availability current without appending identical model messages. + +### Environment directory + +Publish a sorted directory of references, display names, default markers, and +compact access grants. Omit current selection, lifecycle status, and working +directory; environment_read provides these details, including when selection +tools are disabled. Directory ownership and invalidation depend on the +environment feature, not the selected machine. Environment skill and prompt +sources remain bound to their actual environment. + +### Skills + +Both environment and VFS skill menus contain names, descriptions, and SKILL.md +paths. Internal skill IDs and redundant directory paths remain available in +structured metadata but disappear from prompt text. Sort by visible path so +snapshot identity changes do not reorder an unchanged menu. + +Environment discovery failures retain the last successful catalog only for the +same environment and configured discovery scope. Persist that scope with the +observation so recovery works after worker restarts. Availability and warnings +remain API metadata; the menu describes paths as discoveries whose current +contents are obtained through file reads. Never retain another environment's +skills or reuse an observation after configured roots, working directory, or +access change. Revoking the attachment discards its advertised paths. Older +observations without scope metadata need one successful discovery before they +can be retained on failure. Repeated failures share a stable API warning; +detailed transport errors remain in runtime logs. + +### Other catalogs + +VFS mounts retain paths and access and describe workspace versus snapshot +storage without exposing internal IDs or snapshot hashes. Sub-agent revisions +remain provenance; only changes to visible choices, descriptions, availability, +or limits append a new menu. Bot directory publication already deduplicates +unchanged contents. Tool definitions remain independent of environment status. + +### Environment handles + +Preserve already-short IDs. Long generated IDs use `env:` plus twelve UUID hex +characters; other long IDs use twelve SHA-256 hex characters. Resolve handles +against authorized attachments, reject ambiguity, and continue accepting full +IDs. Use the same representation in catalogs, environment control tool results, +and job result handles. Resolve to canonical IDs before registry lookup, routing, +workflow effects, or authorization. Durable environment records keep canonical +IDs; stored model-facing tool results contain short references.

Ordinary reads, writes, edits, patches, +searches, and transfers retain their existing outputs and do not implicitly +create file attachments. In particular, no file-reference header is injected +into those results. A capture exports environment bytes into VFS; the agent +then references the captured file explicitly. Snapshot references remain usable +when capture publication encounters a concurrent workspace change. + +Obtaining an attachment makes it available in that session. Passing it to a +parent additionally requires mentioning its link in the successful final +answer. Only referenced, known, unambiguous attachments travel in the result +envelope for both `agent_run` and `agent_spawn`/`await`. Intermediate files stay +with the child. The descriptor travels with the text, so the recipient does +not need access to the child's session or workspace. Nested handoff follows +the same rule. + +Media follows the existing behavior: reading or producing an admitted image or +PDF supplies media to the model, and mentioning its `media:` link in the final +answer forwards it. Images are immutable blobs too, and may also have a VFS +path. A file reference to an image does not automatically load it as model +input. Receiving a file attachment preserves a link; receiving media retains +the existing native-media admission rules. + +Message presentation follows Markdown for both reference types: `[label](ref)` +renders a text link, while `![description](ref)` displays an image inline and +links it to the blob viewer. Image syntax for a non-image falls back to a file +link. Browser previews do not admit media into model context or change attachment +handoff. Either syntax in a successful final answer can forward the attachment. + +## Identity and representation + +Full SHA-256 blob references remain the authoritative content identity. Short +handles are model-facing aliases over recorded descriptors, not permissions or +a universe-wide registry. Media keeps its existing `media:` handle. File +attachments use `file:` followed by 24 hexadecimal content-digest characters. +Equal bytes have equal file handles; names and optional sources are descriptive +metadata, not a second content identity. Ambiguous handles must not silently +select different bytes. + +Tool and sub-agent outputs carry typed attachments: media descriptors or file +descriptors. File descriptors contain a full blob reference, name, optional +media type, and optional source metadata. A source identifies its kind, record, +and path; VFS-specific resolution belongs in the tools/runtime adapters. +The deterministic engine records attachments on completed calls and forwards +runtime-prepared attachments through workflow results without interpreting +filesystem origins. Attachments have a dedicated field; they are not encoded +as tool effects. Public projections expose that field for clients. + +Generic filesystem interfaces and operations remain unaware of attachments. +Explicit reference creation resolves one immutable manifest at the VFS tool +boundary. It requires neither a task-local collector nor changes to generic +read/write implementations. The reference tool's own output tells the model +the handle and how to cite it; unrelated tool output stays unchanged. + +## Resolution, access, and lifetime + +Platform resolves file links from recorded attachments, including historical +completion pages. The parent records handed-off descriptors in its own result. +Unknown, malformed, or ambiguous references are unavailable. Renames, +overwrites, deletion, and workspace detachment do not retarget an attachment. +Source information is optional navigation context and never controls the bytes +opened by a file link. +References created from attached workspaces record the workspace ID and relative +path. The blob viewer links back to both the conversation and that workspace; +the workspace file link follows the current path while the blob remains the +referenced version. VFS mount metadata stays in the tool context, outside generic +filesystem interfaces, and survives sub-agent handoff. + +Canonical references on recorded attachments and result-envelope containment +edges keep the bytes reachable for the receiving session. A digest embedded +only in prose does not establish retention. File descriptors have a separate +bounded budget from native media and never consume image/PDF input capacity. + +Blob reads use existing universe-scoped permissions.
