With two people in parallel, that is roughly three to +four months of calendar time, plus the spike in the sequence below. + +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.** For Option C, the shared code + must stay deterministic and avoid custom wakers (the TMPRL1100 constraint). + That suggests a sans-IO state machine, as `bots::controller::state` already + is, rather than shared async code. +- **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)?

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. +- Tool calls and tool results are separate entries (`ToolCall`, `ToolResult`), + one per call.

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. +- **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. + +### 2. Check the whole request against provider limits + +After lowering, each adapter compares the request with its row of the limits +table: image block count, per-image encoded bytes, and total body bytes. + +- **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]`. + Media from the current run's input and from the latest tool batch is never + omitted, because the model must see what it just asked for. +- **The cut point moves in steps.** Which media is omitted is a pure function + of the context, so retries produce identical requests. The boundary moves + only when the request crosses the limit, and then it drops to a low-water + mark well below the limit, so a growing session invalidates its prompt + cache rarely rather than every turn. +- **If the protected newest media alone does not fit**, the adapter fails the + turn with a typed error before any provider call. Admission bounds a single + result to eight items within the per-image budget, so this needs unusually + wide parallel tool batches. + +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 request totals do. + +### 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. +- 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. Redact context entries in place + +`session/context/redact { sessionId, entryIds }` replaces the content of each +named entry with a fixed placeholder chosen by the engine. The engine gains a +`RedactContextEntries { expected_revision, entry_ids }` command and an +`EntriesRedacted { base_revision, entry_ids, reason }` context event. + +**In place, not removal.** A redacted entry keeps its entry ID, position, kind, +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. Swapping content 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. + +**The engine chooses the placeholder.** Clients name entries; they never supply +replacement content, so this is a repair operation, not a general +context-editing API. + +| 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]` | + +Rejected, request-level: + +- tool calls, assistant output, reasoning, and provider-opaque entries, whose + content is provider-signed or provider-shaped; +- any redaction while a run is active, or while compaction is pending; +- unconsumed run input or steering, by the existing guard. + +An ID that is not in active context, or is already redacted, reports `absent`, +so retries are idempotent. The response reports a result per ID. + +The original content stays in the event log. The web transcript resolves +`media:` handles from transcript history, so a redacted image still renders +there, beside the redaction event. A sub-agent hand-off resolves links against +the child's active context, so a redacted image no longer travels with it. + +Redaction is available through the API and the runtime CLI. There is no web +affordance and no automatic redaction. + +## How a failing session recovers + +| Failure | Handled by | Automatic | +| --- | --- | --- | +| Image over a provider's pixel or per-image byte limit | Normalization (Decision 1): the request is never built | Yes | +| Request over a provider's image count or total size | Request limits check (Decision 2): oldest media omitted | Yes | +| Any other rejection: a limit not yet in the table, an entry a provider no longer accepts, a provider change | `RequestRejected` (Decision 3), then redaction by an operator (Decision 4) | No | + +The runtime repairs automatically only what it can predict.

It now lowers to between_tools on Sonnet 5.5 and to adaptive thinking at low effort where thinking cannot be turned off; older models keep disabled. Display and block_binding are only defaulted when thinking is on, since thinking-off types reject both. Compaction requests replay earlier thinking but sent no thinking config, so they carried no block_binding and failed on enforced accounts after an image edit. On models that think by default they now send an explicit adaptive config carrying the binding policy. Live-verified on claude-opus-5-5 and claude-sonnet-5-5, and through the hosted sessions and runs suites with the strict binding policy. Documents LIGHTSPEED_ANTHROPIC_THINKING_PREFIX_MISMATCH and records slice 1 progress in the P186 roadmap doc.

The classification now crosses the I/O boundary: - CoreAgentIoError::Rejected carries the provider's message unchanged. - The hosted activity and the test runner turn it into a Rejected generation whose failure blob is that message. - The engine records TurnOutcome::Rejected and fails the run as RunFailureKind::RequestRejected. It only records the classification. - The public RunFailureKindView gains request_rejected; the contract and TypeScript client are regenerated. - The web transcript and CLI chat say the provider rejected the request. - Each adapter logs, on a rejection, which context entries each provider message or input item holds, since provider errors cite positions. Verified by unit and replay tests, an Anthropic runtime live test, and a hosted live test where OpenAI rejects an undecodable image and the run fails as request_rejected with OpenAI's message verbatim.

Every later run resent it. session/context/replace { sessionId, entries: [{ entryId, item }] } replaces active entries where they sit. It follows session/context/append: items are InputItems converted by the same path, and results report replaced, unchanged, absent, or failed with an admission failure per entry. The engine command and event mirror ReplaceContextPrefix with ids instead of a key prefix, reusing ContextEntryInput and ContextEntry: ReplaceContextEntries / EntriesReplaced, projected as contextEntriesReplaced. A replacement keeps the entry's id, position, key, source, and kind, so a tool result stays paired with its call; only tool results and user messages qualify, a tool result takes only text, and replacement is refused during a run. Adapters need no changes: a replaced image is plain text everywhere. The CLI gains `session context list` (from session/read), `replace`, and a `redact` shortcut that sends standard "removed by operator" placeholders. A hosted live test now continues past a provider rejection: it replaces the undecodable image and runs the same session again.

Each request now carries at most 100 media items and 24 MiB of encoded media, the same budget for every provider and model. RequestMedia prepares every image and PDF once, omits the oldest when the request is over budget, and hands the prepared copies to the adapter, so the budget adds no blob reads. Omitted media is sent as "[image · media:… · omitted from this request to stay within provider limits]". The omission count is rounded up to chunks of 10, so the cut point moves once per chunk of new media instead of every turn, but never drops below the four newest items that fit. It is a pure function of the context, so retries send identical requests. All three adapters and compaction requests share it. Live-verified on Claude Opus 5.5: crossing the budget after a thinking turn fails under the strict binding policy and continues under drop_block.

Existing compaction paths have been reviewed +and live-tested; the defaults, native Anthropic standalone path, and recovery +behavior below remain to be implemented. + +Builds on [provider-native compaction](archive/p64-provider-native-compaction.md) +and [provider-safe context repair](p186-provider-safe-media-and-context-entry-redaction.md). +Supersedes the former proposal's opt-in defaults, manual-only standalone +behavior when its threshold is absent, and deferral of automatic fallback. + +## Outcome + +Long-running sessions use engine-managed standalone compaction by default, +with native operations for supported Responses and Anthropic Messages routes +and Lightspeed-managed summarization for Chat Completions providers, including +OpenAI and DeepSeek. 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. It does not change the configured policy. +Compaction changes active context through ordinary events; durable history and +original content remain subject to their existing retention policies. + +## Current implementation and verification + +The repository currently provides: + +- `ContextConfig.compaction: Option` with Disabled, + ProviderTriggered, and ProviderStandalone modes. Omission currently disables + compaction for every route; the UI labels that omission Engine default. +- Provider-triggered compaction for OpenAI Responses and Anthropic Messages, + including optional thresholds, native request lowering, exact native block + retention, and deterministic pruning. Chat Completions rejects this mode. +- OpenAI Responses standalone `/responses/compact` through the runtime, + in-process runner, and hosted worker. +- Anthropic Messages and Chat Completions standalone compaction through ordinary + summary generations. Anthropic's new native on-demand operation is not wired. +- Manual compaction admission restricted to ProviderStandalone while no run is + active or queued. Automatic standalone compaction requires an explicit + threshold and runs only at that idle boundary. +- A standalone snapshot covering all eligible conversation entries, with no + protected recent tail. Instructions and current catalogs survive separately. +- Typed provider context-length classification in `llm-clients`, but the generic + executor maps it to an ordinary request rejection carrying the message. + In-band context-limit finishes have a separate path, without the recovery + sequence proposed here. +- OpenAI standalone result handling that retains compaction items but filters + other returned items. This needs correcting to preserve the complete native + compacted window. + +Live verification performed during the preceding implementation work: + +| Route | Verified behavior | +| --- | --- | +| OpenAI Responses | Provider-triggered capture, engine pruning, continuation, manual standalone, and threshold standalone | +| Anthropic Messages, Sonnet 5 and Opus 5.5 | Provider-triggered capture, engine pruning, and continuation | +| Anthropic Messages, Opus 5.5 | Manual and threshold standalone through the existing summary-generation path | +| OpenAI Chat Completions, GPT-5.5 | Standalone summary facts and continuation | +| DeepSeek Chat Completions, V4 Pro | Standalone summary facts and continuation using the selected endpoint and credentials | + +These checks establish the existing paths, not native Anthropic on-demand +compatibility, automatic defaults, overflow recovery, or universal support by +compatible endpoints.

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. + +## 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. Record only +provider-neutral observations needed to replay decisions. + +Implement through existing runtime, in-process runner, and hosted worker +boundaries rather than adding a separate orchestration framework. + +- [x] Review existing implementation and provider contracts. +- [x] Live-verify existing triggered and standalone paths as recorded above. +- [ ] Define capability resolution, Engine default upgrade semantics, and + requested/effective policy facts; implement validation and projections. +- [ ] Preserve typed context-length failures and add a replayable recovery + lifecycle without terminalizing the run before recovery is considered. +- [ ] Preserve the full OpenAI standalone output; implement native Anthropic + on-demand requests, signed-block replay, and effective strategy transitions. +- [ ] Add protected-tail selection within active runs, bounded rolling chunks, + repeated compaction, and summary validation.

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.

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. Handle collisions must never select an arbitrary +machine; presentation can fall back to full IDs for colliding attachments. + +## Verification and progress + +- [x] Metadata-only upserts preserve rendered context and replay correctly. +- [x] Environment directory survives selection and status changes. +- [x] Skill and VFS menus omit opaque IDs and redundant fields. +- [x] Failed discovery preserves only matching observations and API diagnostics. +- [x] Short handles work for environment controls and job references, with full + ID compatibility and ambiguity rejection. +- [x] Scoped Rust tests and relevant generated-contract checks pass. + +Validation: + +- Library suites for engine, tools, temporal-workflow, temporal-server, + llm-runtime, and test-support: 1,190 passed; the existing external ffmpeg + smoke test remains ignored. +- Discovery regression exercises local mock transport timeouts, incomplete + scans, recovery, and revoked access. It passes with retained stale menus. +- Metadata replacement replay also rejects edits to catalog text, + supersession links, and superseded versions. +- Provider tool request fixtures regenerated through an explicit ignored + updater and verified by the normal parity test. +- Workflow integration contract verification and workspace Clippy with all + targets and warnings denied; formatting and diff whitespace checks. + +No database ID migration or change to the public environment ID format is +required. Historical context continues to render its original stored text. +Existing selection-bound environment directories are replaced on refresh; +subsequent selection changes preserve the directory. Real menu edits continue +to supersede old versions under the existing retention and compaction policy.
