From 8380cebfc53789cdb2e1d68b55b48978d6f56264 Mon Sep 17 00:00:00 2001 From: anandgupta42 Date: Thu, 27 Aug 2026 10:43:05 -0700 Subject: [PATCH 01/58] fix(session): head-truncation fallback for unrecoverable context overflow Summarize what fits instead of terminating the session when a single oversized tool result pushes input past the context window between assistant turns. Previously the recovery compaction would resend the full conversation, overflow the same way, and terminate with "Session too large to compact". fitHead drops oldest head messages (token budget = input limit minus max output minus slack, with a safety factor) until the summarization request fits. A lossy summary beats a dead session. compaction_head_truncated telemetry event added; 3 unit tests. --- .../opencode/src/altimate/telemetry/index.ts | 7 +++ packages/opencode/src/session/compaction.ts | 52 +++++++++++++++- .../test/session/compaction-fithead.test.ts | 62 +++++++++++++++++++ 3 files changed, 119 insertions(+), 2 deletions(-) create mode 100644 packages/opencode/test/session/compaction-fithead.test.ts diff --git a/packages/opencode/src/altimate/telemetry/index.ts b/packages/opencode/src/altimate/telemetry/index.ts index 45dce393fe..428d08091e 100644 --- a/packages/opencode/src/altimate/telemetry/index.ts +++ b/packages/opencode/src/altimate/telemetry/index.ts @@ -207,6 +207,13 @@ export namespace Telemetry { trigger: "overflow_detection" | "error_recovery" attempt: number } + | { + type: "compaction_head_truncated" + timestamp: number + session_id: string + dropped_messages: number + kept_messages: number + } | { type: "tool_outputs_pruned" timestamp: number diff --git a/packages/opencode/src/session/compaction.ts b/packages/opencode/src/session/compaction.ts index 8dbc383bdf..06ca2acfac 100644 --- a/packages/opencode/src/session/compaction.ts +++ b/packages/opencode/src/session/compaction.ts @@ -203,6 +203,33 @@ export namespace SessionCompaction { return undefined } + // altimate_change start — head-truncation fallback for un-compactable sessions + // A session can overflow so far past the window (huge tool result landing in + // one turn) that the summarization request itself no longer fits, which used + // to terminate the session with "too large to compact".

This commit addresses the remaining genuine, small, safe items: - `compaction.ts`: redundant ternary cleanup; `PIN_SUMMARY_ADDITION` now gates on a positive pin budget for the session's model, not just `pinEnabled`, so a small-window session can't have the task dropped from both the summary and the pin - `llm.ts`: `addHistoricalToolStubs` now gates its empty-tools bypass on the summarizer's explicit `toolChoice: "none"`, not on an empty tool set alone, so a normal turn whose tools were permission-stripped still gets historical stubs - `starvation.ts`: `resolveConfig` clamps non-positive thresholds to their default (a configured `0` no longer trips the breaker immediately); `normalizeArgs` no longer mislabels shared (non-circular) references as `[circular]` - `processor.ts`: the compaction summarizer's own generation no longer consumes a pending nudge/starvation directive it can't act on; braced the `tool-input-start` switch case (Biome `noSwitchDeclarations`) - `idle-done.ts`: a session that never mutated a file can no longer satisfy the "verify after last write" precondition - `run-accounting.ts`: DONE-text and finish-reason are now paired by messageID instead of independently-overwritten globals; `serializeSessionError` falls back to a native `Error`'s top-level `.message` - `run.ts`: forwards the `--audience` directive to the idle-done challenge prompt; aborts the challenge event subscription on every path, not just failure; clamps retry count/delay env overrides to sane upper bounds - `config.ts` (V1 + V2): bounds `pin_window_fraction` to `[0, 1]`; the V2 schema also gained the `context_safety_fraction` bound the V1 schema already had (direct-V2-load path was previously unbounded); fixed a pre-existing fast-check float32 arbitrary failure this uncovered - `truncate-core.ts`: moved the self-reexport to the bottom of the file - `.github/meta/harness-review-followups.md`: corrected two stale line references; appended newly-deferred items (prompt retry idempotency, fitHead prompt-size reservation, ledger view staleness across compactions, uncounted-tail tool-result gap, a residual truncation edge case, and the export-namespace convention gap in the 5 new modules — consistent with ~69 pre-existing files, better fixed holistically) Regression tests added alongside each behavior change. Several other reported findings were verified already fixed by prior commits on this branch (fence-parity DONE detection, compaction breaker/outcome ordering, fitHead user-boundary cuts, mutation-credit-on-success, tool-call-id prototype safety, challenge-suppression scoping, config fraction bounds, unknown-model cap, truncation budget edges, pin invariant arithmetic) and a few were false positives (stream() ordering, tool-call-id replay test premise, timeout word-boundary matching, and the deliberate annotate-by-default starvation rollout gate) — full disposition posted on the PR.

Most reported items were already fixed on this branch; these are the residual confirmed ones. - `processor.ts`: the compaction summarizer runs through the same processor under the session's own id, so it shared the working agent's per-session starvation tracker — its single mutation-free step advanced `turnsWithoutMutation` for the real agent (spurious would-fire telemetry in the default annotate mode, a premature directive in armed mode). Directive delivery was already exempted for summary messages; starvation accounting now is too, via the same `sbExempt` gate. - `starvation.ts`: two raw NUL bytes were embedded directly in source as string-literal separators, which made the file classify as binary — `grep`, `file`, and review tooling skipped it entirely. Replaced with the equivalent unicode escapes; the runtime strings are byte-identical. - `config.ts` / `starvation.ts`: `max_turns_without_mutation` is counted per generation step, not per user message; the schema description and the threshold rationale said "assistant turns", which misleads operators tuning it (one user message routinely spans several read-only steps). - Tests: pin the summarizer exemption in the gate suite, and add two idle-done cases that drive the detector in production event order (step-finish part, then the step's snapshot patch part) — the existing fixtures emit the patch first, which would mask an ordering regression in the mutation-versus-verify comparison. - `harness-review-followups.md`: record the four items deliberately deferred from this pass (historical tool-stub omission on the summarizer path, repeat-signature accumulation on successful calls, the run record's stop-reason fallback, and converging the remaining test fixtures on production ordering). Gates: `bun test test/session/ test/cli/` (only the 2 known prompt.test.ts timeout flakes fail), `bun run typecheck` clean, marker guard clean.

Every item is a defect in code this branch introduced, several of them in the earlier fixes themselves. - `config`: the compaction safety-fraction bound rounded UP to the nearest float32 (`Math.fround(0.1)` is ~0.10000000149), so a config carrying the documented minimum `0.1` failed to decode in both the V1 and V2 schemas. Replaced with a shared `SAFETY_FRACTION_MIN` that rounds DOWN, which keeps the exact-float32 bound the property-test generator needs and accepts the advertised `[0.1, 1]` range. - `session/termination.ts`: normalize `\r\n` and bare `\r` before scanning fences. On CRLF input the interior lines kept a trailing `\r`, the closing fence failed its whitespace-only check, and every fence stayed open — a genuine completion assertion was rejected. - `session/termination.ts`: a backtick run whose info string contains a backtick is not a fence opener (CommonMark). Treating it as one let the next backtick run read as its closer and exposed the block interior. - `cli/cmd/run.ts` + `run-accounting.ts`: clamp the retry backoff to the timer range. Bounding the retry count and base delay separately was not enough — at the accepted maximums (20 retries, 60s base) the compounded delay runs past the signed 32-bit ceiling, and an overflowing timeout fires after ~1ms, producing exactly the tight retry loop those bounds exist to prevent. - `session/prompt.ts` + `cli/cmd/run/run-mode.ts`: scope run-mode task pinning to the current run. `run --continue` / `--session` / `--fork` resume a session whose first user message belongs to an earlier invocation, so pinning "the first user message" re-injected a completed or conflicting task as authoritative over the summary and the current prompt. Resumed runs are marked and use the interactive rule (latest substantive instruction). - `cli/cmd/idle-done.ts`: classify mutating command forms, not just heads. `sed -i`, output redirection, and always-writing heads left the mutation watermark stale when snapshots are disabled and no patch part is emitted, so an earlier green verification kept satisfying the build-after-last-write precondition and the challenge could claim nothing happened after it. - `session/compaction.ts`: record the apply_patch move DESTINATION rather than the source (the source path no longer exists), skip deletes, emit no ledger at all when the budget cannot fit even the header (`ledger_max_tokens: 0` is accepted by the schema), and restrict the carry-anchor basename fallback to bare filenames so an unrelated same-named file cannot mark a qualified artifact `[verified]` — a wrong fact that append-only status never corrects. - `test/session/nudge-arbiter.test.ts`: move the 129-session LRU cleanup into `finally` so a failed assertion cannot leave global state that evicts other suites' directives. Four further findings are recorded in `.github/meta/harness-review-followups.md` rather than changed here: the dispatch cap on failure-path output, the underlying "not read-only implies verification" inference, `--max-turns 0`, and child-process inheritance of the new run-scoped marker. Gates: `bun run typecheck` clean (13/13 packages), marker guard clean across 13 upstream-shared files, `test/session/` 954 pass (2 known `prompt.test.ts` 5s timeouts), `test/cli/` 824 pass, `packages/core` config suite 45 pass.

Every change below was verified against current code first; threads whose fix had already landed in an earlier pass were answered with evidence and resolved rather than re-fixed. Truncation (`tool/truncate-core.ts`) - A boundary line longer than its byte share selected NOTHING, so a middle preview of a single long line reached the model as a bare truncation marker with zero content. Head/tail now fall back to a UTF-8-safe byte prefix/suffix. - The two middle byte budgets were each floored at 1 and could sum above `maxBytes`; the head share is clamped and the tail share may be 0. - A middle preview that degraded to tail-only rendered a leading blank line. Compaction (`session/compaction.ts`) - The state ledger was built from the compaction-FILTERED message view, so from the second compaction onward it forgot every tool event an earlier compaction had hidden — the opposite of the cross-compaction fidelity it exists for. `ledgerHistory()` now reads the unfiltered session stream, with a fail-safe fallback to the caller's view. - `ledger_recent_calls: 0` rendered EVERY call (`slice(-0)` is `slice(0)`). - The ledger token budget was reserved from the tail budget even with both `state_ledger` and `summary_carry` disabled. - A carried artifact written as `./src/foo.ts` never matched a ledger path. - The livelock `pinState` map was unbounded; it now uses the same 128-entry LRU as the starvation and nudge stores. Session (`session/prompt.ts`, `session/processor.ts`, `session/nudge.ts`) - The task-pin `` framing was added after the body had spent the whole cap, so the rendered pin exceeded its advertised hard cap. - The uncounted-tail estimate skipped tool results attached to the last finished assistant message itself — exactly the single oversized result the proactive overflow check exists to catch. Extracted as `estimateUncountedTail()`. - The per-result dispatch cap was enforced only on successful tool results; a failed call with very large stderr still entered the conversation unbounded. - The step-finish outcome ordering is now the exported `resolveFinishOutcome()` so its unit gate exercises production code instead of a local copy of it. - The nudge arbiter replaced pending directives by source+kind but delivered the EARLIEST match, so a generation crossing two rungs of the doom-loop ladder delivered the stale nudge and dropped the escalation. Run mode (`cli/cmd/run.ts`, `cli/cmd/idle-done.ts`, `tool/bash.ts`) - Prompt retries were not idempotent: `session.prompt` runs the task synchronously, so an ambiguous transport failure could arrive after the server accepted the POST and a retry ran the task twice. The attempt now carries a stable `messageID` and the retry is skipped when that message already landed. - `--max-turns` was unvalidated: a non-numeric value became NaN and silently disabled the budget, a negative value aborted on the first step. - The mutation detector missed numbered-descriptor writes (`2> err.log`), and `apply_patch` was not classified as a mutating tool, so a stale green verify could still satisfy the idle-done gate. - With no verify command configured, every non-read-only command counted as a verification candidate — a zero-exit `rm` stood in as evidence the work was done, and the `MUTATING_HEADS` branch was unreachable. - `ALTIMATE_RUN_MODE`/`ALTIMATE_RUN_RESUMED` leaked into bash child processes, arming run-mode-only mechanisms in nested interactive sessions. Tests - New: `test/session/compaction-ledger-history.test.ts` (instance-backed; proves the filtered view loses a pre-compaction write and the fix retains it). - Extended coverage for every behavioural change above, plus `estimateUncountedTail` and `resolveFinishOutcome`, which had none. - Three suites mutated `ALTIMATE_CONTEXT_SAFETY_FRACTION` process-wide and deleted it unconditionally in teardown; they now save and restore it. Gates: typecheck clean, marker check clean, lint unchanged from baseline (1 pre-existing `bun-types` tsconfig error), 2321 pass / 0 fail across the session, cli and tool suites.

Four were regressions I introduced; two were weaknesses in how I fixed things. Regressions in the fifth pass, now corrected: - The per-result dispatch cap was extended to FAILED tool results, but `ToolResultCap.apply` appends a hint that says *"The tool call succeeded"*. An oversized error was therefore persisted with success wording, so the model could read a real failure as a truncated success. `apply()` now takes an `outcome` and emits an error-specific hint that states the failure is real. - The nudge arbiter was changed to replace pending directives by SOURCE alone. That is wrong: four independent detectors register under `starvation_breaker` (`doom_loop_nudge`, `doom_loop_status_check`, `repeat_signature`, `starvation`) and they fire at different points in a step, so a later WEAKER detector could clobber a stronger directive that had already fired — the opposite of the intended fix. Replacement is back to source+kind, and `take()` now ranks kinds by explicit strength within the winning source. - The prompt-retry acceptance probe failed OPEN: if the probe itself threw, the message was treated as absent and the task was resent — exactly the duplicate execution the mechanism exists to prevent. Acceptance is now three-valued. Only a definitive 404 from a reachable server permits a retry; an unknown state fails the run with a clear message rather than risking a second execution or a silent hang. - Stripping `ALTIMATE_RUN_MODE` from bash child environments also removed an explicit opt-out (`=0`/`false`), so a nested `run` would re-apply the default and turn run mode back ON. Only an ACTIVE marker is stripped now. Weaknesses in the fifth pass, now addressed: - `ToolResultCap.resolve` resolved the safety fraction AFTER the unknown-model branch returned, so a configured fraction never scaled that fallback. - The run-mode child-env test asserted on `bash.ts` source text, which cannot catch the strip being relocated, applied to a different object, or skipped — the same false-confidence problem flagged elsewhere in this review. The logic is now the exported `stripRunModeMarkers()` and the test exercises it. Tests: strongest-wins and weaker-does-not-displace ordering for every `starvation_breaker` kind; error vs success truncation wording (and that the error hint still respects the cap); configured fraction scaling the unknown-model fallback; and behavioural coverage of the marker strip including opt-out survival. Gates: typecheck clean, marker check clean, 2411 pass / 0 fail.

The ATTACHED form (`make check$(rm x)`) was already rejected, but only incidentally — `$` is not an accepted prefix boundary, so configuredMatches was false. With a SPACE the boundary check passes and the substitution runs as an argument to the trusted verifier. Neither guard saw it: the tail scan only looks after an `&&`, and hasUnsafeVerificationControl only looks for `;`, `|`, `&` and newlines, none of which appear in `npm test $(rm report.csv)`. The run therefore counted as green verification of a worktree it had just mutated, satisfying precondition (i) and letting the run terminate as done. The substitution pattern is now a shared SUBSTITUTION constant, applied to the suffix after the configured prefix.

Also corrects the comment above the curl-context fix, which overclaimed.

Verified before the fix: an AWS key, an OpenAI key, curl basic-auth and a signed URL all reached the mask intact. Reuses redactLedgerDetail rather than adding a second redactor. Two things that fix had to get right, both found by measurement rather than review: - redactLedgerDetail begins with Telemetry.maskString, which collapses any QUOTED string to "?". Redacting JSON.stringify(v), or the joined `k: v` text, therefore erased every argument — the mask was safe and useless. Redaction now applies to string LEAVES, with structure preserved, plus an explicit check on sensitive argument NAMES, which value-level matching cannot see (an opaque `api_key` value matches no pattern). - Walking arbitrary tool input hung on the existing circular-argument test, and redacting an unbounded first line hung on the existing 1.5 MB output test — redactLedgerDetail costs 6.2s at 100 KB. Cycles are guarded and still degrade to "[unserializable]"; redaction runs over a 1024-char window, of which only 80 characters are ever retained.

The five modules this PR introduces — termination, nudge, tool-result-cap, idle-done, run-accounting — used the namespace form. Contained to the five files. The prescribed `export * as Foo from "./foo"` projection means consumers keep importing { Foo } and calling Foo.bar(), so not one call site changes; the rewrite dedents each namespace body and adds the self-reexport. termination.ts carries the run-termination protocol, so this was verified as behaviour-preserving rather than merely green. session + cli suites before and after: 1914 pass, 2 fail, 17 skip, 45 todo, 1978 across 119 files — identical, with an identical failing set (the two known pre-existing 5000ms prompt.test flakes). termination.ts was converted and verified first, alone, before the other four. Also drops three now-unnecessary type assertions in redactArgValue, returning the repo lint warning count to its 6201 baseline. --- packages/opencode/src/cli/cmd/idle-done.ts | 960 +++++++++--------- .../opencode/src/cli/cmd/run-accounting.ts | 600 +++++------ packages/opencode/src/session/compaction.ts | 6 +- packages/opencode/src/session/nudge.ts | 214 ++-- packages/opencode/src/session/termination.ts | 264 ++--- .../opencode/src/session/tool-result-cap.ts | 342 +++---- 6 files changed, 1193 insertions(+), 1193 deletions(-) diff --git a/packages/opencode/src/cli/cmd/idle-done.ts b/packages/opencode/src/cli/cmd/idle-done.ts index 7bdbcd5aa1..ec682a6f8f 100644 --- a/packages/opencode/src/cli/cmd/idle-done.ts +++ b/packages/opencode/src/cli/cmd/idle-done.ts @@ -38,520 +38,520 @@ // loops.
