Conversation
…flow 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.
Overflow check now estimates tool output appended since the last recorded usage, so an oversized result triggers compaction BEFORE the request bounces off the context wall instead of after. Builder prompt gains a mandatory finish protocol: literal contract diff against the stated task before declaring done, a final build so the manifest reflects every change, and commit-over-explore when turns run low.
- fitHead now truncates on turn boundaries. A head that starts mid-turn (assistant/tool messages with no leading user turn) was rejected by providers with a 400, defeating the overflow fallback entirely. - uncountedTail estimation now uses the shared token estimator instead of a chars/4 approximation, which undercounted the JSON/code tool output it targets. Turn-boundary regression tests added.
…tion, id sanitation, honest accounting
Evidence-driven harness reliability improvements, Wave 1:
- `compaction.ts`: continue-message now carries `format`/`tools`/`system`/
`variant` like the replay branch (stops silent permission-surface widening
after auto-compaction); summarizer called with explicit `toolChoice: "none"`
plus an empty-summary retry-once-then-error guard (kills post-compaction
amnesia from tool-call summaries)
- `llm.ts`: skip stub-tool injection when a request declares zero real tools
(summarizer fallback path)
- `truncate.ts`/`truncation.ts`: bash output now middle-truncates (1/3 head +
2/3 tail) via a shared `truncate-core.ts` so trailing verdict lines and
leading first-errors both survive; twin modules deduped onto one core
- `processor.ts`/`message-v2.ts`: deterministic sanitation of malformed
(non-string) tool-call ids with atomic call/result pair aliasing at
ingestion and replay
- `run.ts`: turnCount excludes compaction-machinery steps (via
`run-accounting.ts` agent lookup); real error serialization (never `{}`);
nonzero exit on fatal abort; bounded logged retry on provider 5xx/timeout;
dual-attribution termination fields (`why_model_stopped` /
`why_harness_stopped`) in run output
91 new/changed tests added; upstream marker check clean.
…g, facts ledger, starvation breaker, nudge arbiter Four behavioral interventions, corrected mechanisms per adversarial review: - `session/termination.ts` + `processor.ts` + `cli/cmd/idle-done.ts`: explicit `DONE`-token termination (never bare finish-stop); run-mode-only idle-done fallback with build-after-last-write ordering, one-shot confirm-DONE challenge with a recursion guard; `done_reason` emitted; accurate overflow messaging - `session/prompt.ts` + `compaction.ts`: original task pinned verbatim through every compaction (mode-aware selection, dynamic cap with livelock guard, deterministic contract card of extracted literals) - `compaction.ts`: deterministic corroborated-facts ledger on continue messages; append-only summary carry; first-person summary framing - `session/starvation.ts` + `session/nudge.ts`: write-starvation breaker (annotate-only default, config-armed), repeat-signature loop detection, doom-loop guard fixed under yolo mode; single-directive nudge arbiter (termination > breaker > budget precedence) Interactive TUI behavior unchanged (run-mode gating verified). 209 new tests added; upstream marker check clean.
Config-exposed knobs for the Wave 2 core-loop interventions: write-starvation breaker mode/thresholds, idle-done fallback gating, and task-pin sizing. Defaults carry first-principles or evaluation-corpus provenance and are never hardcoded constants.
…per-tool-result dispatch cap, run-mode default - `compaction.ts`: `isOverflow()` now triggers against `effectiveContextLimit()` = context * `context_safety_fraction` (default 0.65, env `ALTIMATE_CONTEXT_SAFETY_FRACTION`, config `compaction.context_safety_fraction`), with a 4000-token floor. Absorbs up to ~1.55x token-estimator undercount on dense SQL/JSON that previously overflowed the real model window. - NEW `tool-result-cap.ts`: hard dispatch-time cap on every tool result — `min(config dispatch_max_tokens, byte-derived cap, 15% of effective limit)` with middle truncation + long-line chunking; closes the single-giant-result bypass where one query dump jumped a small conversation past the context wall in one step. - `processor.ts`: cap enforced on every completed tool result before persistence. - `run.ts` + NEW `run/run-mode.ts`: `run` command implies `ALTIMATE_RUN_MODE=1` (explicit `0`/`false` preserved as opt-out) so external drivers get termination semantics without env plumbing; TUI unchanged. - `config.ts`: schema keys `compaction.context_safety_fraction`, `tool_output.dispatch_max_tokens`. - Tests: 32 new across 3 suites (worst-case-fits proof, giant-result replay, run-mode opt-out); existing raw-boundary suites pinned to fraction 1.

Task pin history order inverted
High Severity
taskPinReminder reverses MessageV2.stream before selectPinSource. That stream is oldest-first (the prompt loop treats the last index as latest). After reverse, run mode pins candidates[0] (newest) instead of the original task, and interactive mode pins the last candidate (oldest) instead of the latest instruction — the opposite of the documented mode-aware contract.

Prompt retry can duplicate the run
High Severity
The new retry loop re-invokes sdk.session.prompt/command after timeouts and 5xx. Those APIs wait for the full run, not enqueue. A client timeout or gateway 5xx on a still-running or already-finished session sends the same task again, duplicating work or treating a completed run as a retryable failure.

SUGGESTION: seen is never cleared after a subtree, so shared (non-circular) references are mislabeled [circular]
norm() adds every object to seen on the way down but never removes it on the way back up, so a DAG-shaped input (e.g. { a: obj, b: obj } sharing one reference) renders the second occurrence as "[circular]" even though it is not circular. For true cycle detection the set should track the current recursion path (remove on the way out), not every object ever visited. Tool args are JSON-decoded today so this is latent, but normalizeArgs is exported and feeds the doom-loop/repeat-signature hash — any shared-reference input would be non-canonically normalized.

There was a problem hiding this comment.
When the model follows the new completion nudge and returns a clean stop ending in DONE, this check only terminates if needsCompaction is also true. The normal post-compaction reply should be below the threshold, so it falls through to "continue" and prompt.ts starts another generation, defeating the primary termination protocol and potentially running until a turn limit. Apply explicitDoneStop to every non-summary turn, using it to choose stop before the independent compaction decision.

There was a problem hiding this comment.
On a timeout or connection reset after the server accepted the POST, this loop calls send() again without a stable messageID. The route begins SessionPrompt.prompt at server/routes/session.ts:925 before the streamed response reaches the client, so an ambiguous transport failure can leave the first task persisted or running while the retry creates a second user message and executes the task again. Reuse a fixed message ID or determine that the first attempt was not accepted before retrying this non-idempotent operation.

There was a problem hiding this comment.
For the common run history containing one original user message followed by many assistant generations, there is no later user boundary, so this fallback resets cut to an arbitrary index and returns a head beginning with an assistant message. That recreates the provider-400 condition the preceding boundary logic is intended to prevent, making oversized single-task sessions still impossible to compact. Retain or truncate the leading user turn rather than falling back to a mid-turn slice.

There was a problem hiding this comment.
An empty resolved tool set is not unique to the compaction summarizer: normal requests can reach it after the user's tool allowlist or agent permissions remove every tool. If their history still contains tool calls, this early return removes the exact historical definitions that the surrounding Anthropic compatibility fix requires, so those sessions can regress to provider validation errors. Gate the exception on the summarizer's toolChoice: "none" path rather than on tools being empty alone.

There was a problem hiding this comment.
For a provider-supplied string ID such as __proto__, constructor, or toString, indexing this ordinary object returns an inherited value, so the coercer returns a non-string instead of the sanitized ID; assignment can also interact with the prototype. The downstream toolcalls dictionary has the same exposure, causing pairing or persistence failures for otherwise string-shaped provider IDs. Use Map or null-prototype dictionaries for both alias and tool-call storage.

There was a problem hiding this comment.
When ALTIMATE_RUN_VERIFY_COMMAND is unset, every bash command not recognized by the read-only allowlist becomes a verification candidate. An exit-zero install, cleanup, deployment, custom script, or wrapper command can therefore satisfy the green-verification prerequisite even though it performed no build or test; after the compaction and idle-turn thresholds, the detector aborts the active prompt and issues a false completion challenge. Treat unknown commands as ineligible and require either the configured command or a positively classified verification command.

This serializer only reads data.message, so a native Error—including the network and challenge-send failures passed to it by run.ts—is reduced to the bare string Error and loses its actionable message. That undermines the new honest error reporting exactly on thrown transport failures. Fall back to the object's top-level message property when data.message is absent.

There was a problem hiding this comment.
Every session that reaches auto-compaction is inserted into this process-global pinState map, but production code never deletes entries; resetPinState is only used by tests. A long-lived server therefore retains one entry for every compacted session indefinitely, unlike the explicitly bounded starvation and nudge stores added in the same change. Clear the entry when a session ends or deletes, or apply a bounded eviction policy.

The ledger copies the first 100 characters of raw command, path, or pattern arguments into every post-compaction continuation without any secret filtering. Commands commonly contain authorization headers, signed URLs, passwords, or inline environment values; after the original history is compacted, this newly persists those credentials into later prompts and can expose them to a subsequently selected provider. Store allowlisted metadata or hashes, or run the shared secret-redaction logic before rendering the detail.

For valid small limits such as maxLines: 1, both headBudgetLines and tailBudgetLines are forced to at least one, so middle truncation retains two preview lines despite the configured one-line maximum. The byte split has the same over-allocation when maxBytes is one. Allocate the remainder without forcing both halves nonzero, or special-case budgets too small to contain both a head and tail.

its const declarations, inputStartCallID and part, are scoped locally like the
neighboring tool-call, tool-result, and tool-error cases.
- Around line 388-402: Guard the final stop branch in the doom-loop handling
around starvationStop so it executes only when starvationStop is not already
set. Preserve the existing synthetic Session.updatePart call and stop telemetry
for the first logical stop, while preventing repeated identical calls in the
same step from emitting duplicate records.
- Around line 313-340: Ensure the doom-loop detection in the processor’s
run-mode path enforces a stop for local run sessions instead of only annotating
the ladder. Update the logic around `runMode`, `DOOM_LOOP_THRESHOLD`, and
`PermissionNext.ask` so repeated identical tool calls cannot continue unchecked
while preserving normal non-run behavior.

- Around line 94-105: Update resolveConfig to clamp doomLoopThreshold,
pollingThresholdMultiplier, maxTurnsWithoutMutation, and
repeatSignatureThreshold to a minimum of 1 after reading configuration values,
preserving defaults for unset values; keep disabling starvation behavior
exclusively through mode: "off".

Record non-retryable send errors in RunAccounting.
The @opencode-ai/sdk/v2 client returns non-2xx results with error and no data.info. This branch stores that result and breaks, so accounting.onPromptResult does not call onSessionError. Without another fatal event, accounting.fatal remains false, why_harness_stopped remains "none", and the process can exit with code 0. Handle sendResult.error before onPromptResult.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Emit the stop part and stop telemetry only once per step.
Setting starvationStop does not abort the stream. The ladder condition for the final rung is consecutiveIdenticalCalls >= threshold * 3, so every further identical call in the same step re-enters this branch. Each of those calls emits another starvation_breaker event with action: "stop" and writes another synthetic text part. The transcript and telemetry then carry duplicate stop records for one logical stop.
Guard the branch on the flag.

Replace export namespace wrappers with flat exports and bottom-of-file self-reexports.
The affected modules should follow the repository’s module-organization convention while preserving existing namespaced call sites:
session/termination.tscli/cmd/run-accounting.tscli/cmd/idle-done.tssession/tool-result-cap.tssession/starvation.tssession/nudge.ts
Move members to top-level exports and add the corresponding export * as ... from "./..." self-reexport at the end of each file.

P3: The "large window" comment documents the wrong threshold math. overflowThreshold({base:200000, headroom:20000, fraction:0.65}) yields effectiveBase=130000 and threshold = min(180000, max(110000, 4000)) = 110000, so the fraction cap is floor(110000×0.175)=19250 and the invariant cap is 110000−20000−2000=88000 — not the 180k/31.5k/158k the comment states (which come from the raw base−headroom boundary the code explicitly warns against). The final assertion 4096 is correct, but the explanation misleads a reader debugging the livelock guard.

Because loadFile decodes via Schema.decodeUnknownOption and drops the whole document on any decode failure, a user who previously set context_safety_fraction: 2 or 0.05 (silently clamped at runtime) now gets their entire V1 config silently discarded. Align the behavior with the documented clamp by accepting any number here and relying on the existing runtime clamp in contextSafetyFraction(), and update the annotation accordingly.</comment>

…d hardening fixes Triaged AI-reviewer feedback (claude, cursor, kilo-code-bot, chatgpt-codex-connector, coderabbitai, cubic-dev-ai) against current HEAD; a recent hardening batch had already covered a large share of the reported findings. 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.

Config rejects documented safety-fraction minimum
Medium Severity
The new lower bound uses Math.fround(0.1), which is slightly larger than the JavaScript number 0.1. A config value of 0.1 — the documented minimum and the runtime clamp in contextSafetyFraction — therefore fails schema decode, even though the annotation still describes the range as [0.1, 1].

💡 Codex Review
altimate-code/packages/opencode/src/session/compaction.ts
Lines 439 to 443 in c49df38
Replay the stored observation mask for pruned results
When pruning crosses the threshold, this writes the detailed mask only to state.metadata, but the replay path in message-v2.ts:818-819 ignores that field and still emits the fixed [Old tool result content cleared] placeholder. A repo-wide search finds no other reader of observation_mask, so the model never receives the tool name, arguments, size, or fingerprint that this change computes; use the stored mask when serializing compacted tool results.

There was a problem hiding this comment.
When apply_patch performs a move, its metadata retains the old path in filePath and provides the actual written destination in movePath (tool/apply_patch.ts). Recording only f.filePath therefore makes the post-compaction ledger claim that the deleted source was written while omitting the destination, which can send the continuing agent back to the wrong file; use movePath ?? filePath and account for deletion entries separately.

There was a problem hiding this comment.
For an authored config containing the documented minimum context_safety_fraction: 0.1, Math.fround(0.1) evaluates to approximately 0.10000000149, so this greater-than-or-equal check rejects the ordinary JavaScript/JSON value 0.1. The V2 sibling schema uses the same bound, meaning users cannot select the advertised lower endpoint even though the runtime clamp explicitly supports it; keep the validation boundary at 0.1 and solve the arbitrary-generator constraint separately.
Useful? React with 👍 / 👎.

There was a problem hiding this comment.
The new hard cap is applied only in the successful tool-result branch. A tool-error still persists an unbounded value.error.toString(), and interrupted running tools preserve partial output in metadata that message-v2.ts later replays as a tool result; a failed MCP or shell call with very large stderr/partial output can therefore still overflow the next provider request. Apply the same cap to error text and interrupted partial output before persistence.

Effect Schema isGreaterThanOrEqualTo numeric validation inclusive lower bound Schema.Number.check
💡 Result:
In Effect Schema, you can enforce an inclusive lower bound on numeric values using the greaterThanOrEqualTo filter [1][2]. When building a schema, you typically apply this filter via the pipe method on a base schema like Schema.Number [2][3]. This filter is inclusive, meaning the validated number must be greater than or equal to the specified threshold [1][2]. Example usage: import { Schema } from "effect" // Defines a schema for numbers greater than or equal to 5 const mySchema = Schema.Number.pipe(Schema.greaterThanOrEqualTo(5)) In older versions or specific contexts, you may also see this applied using the check method, such as Schema.Number.check(Schema.isGreaterThanOrEqualTo(5)) [4][5][6]. For modern applications, the pipe approach is the standard pattern for composing filters [2][3]. For other numeric types, similar patterns exist: - BigInt: Use Schema.greaterThanOrEqualToBigInt(5n) [2]. - BigDecimal: Use Schema.greaterThanOrEqualToBigDecimal(value) [2].

Accept exact 0.1 as the inclusive lower bound for context_safety_fraction.
Math.fround(0.1) is 0.10000000149011612, so both schemas reject exact 0.1. Update both schema definitions and add a successful decode case for 0.1.

…accounting hardening - `termination.ts`: a fence-looking line with trailing info-string text (e.g. ```` ```not-a-closer ````) was treated as a valid closer for an already-open code fence; only a run of the same/longer marker followed by nothing but whitespace may close a fence now, matching CommonMark, so a still-open fence's interior `DONE` can no longer terminate a run. - `run-accounting.ts` / `run.ts`: the idle-done confirm-DONE challenge's two abort/finish suppression flags could both still be "fresh" once the challenge reply itself was sent (the interrupted prompt's abort may surface via only one of the two channels), letting a genuine failure of the challenge reply be silently forgiven. `onIdleDoneChallengeReplySent()` now marks the reply as in flight so a later abnormal signal is scored as a real failure, not absorbed by suppression meant for the earlier abort.

Preserve attempts across ineffective compactions
Deleting the counter after every successful summary means the next immediate compaction always starts again at attempt 1, so the attempt > 3 circuit breaker is unreachable for a sequence of successful-but-ineffective compactions. If retained context, the summary, or another additive prompt keeps the session above the threshold, it can therefore continue compacting indefinitely despite the new loop guard; reset the counter only after a normal working generation makes progress or the session ends.

There was a problem hiding this comment.
When operators raise both retry settings within the accepted bounds (for example, ALTIMATE_RUN_RETRY_MAX=20 and ALTIMATE_RUN_RETRY_BASE_MS=60000), later attempts compute delays above the signed 32-bit timer limit; attempt 19 reaches 31,457,280,000 ms. Bun emits a TimeoutOverflowWarning and schedules such a timeout for 1 ms, so persistent provider failures eventually turn the intended backoff into rapid retries. Clamp the computed delay itself to the runtime timer maximum.

When compaction.ledger_max_tokens is configured as 0—which the NonNegativeInt schema explicitly allows—and the session has ledger entries, this loop stops once only the header remains and returns that nonempty header even though it exceeds the zero-token cap. The compaction path then injects unbudgeted ledger text while its retained-tail calculation assumes the ledger costs zero; return an empty ledger when the cap cannot fit even the header.

When --max-turns 0 is supplied, this truthiness check disables the limit entirely, while negative and fractional values are also accepted and produce inconsistent behavior rather than a CLI validation error. For a governance control advertised as a maximum, an explicit zero must not silently become an unlimited run; require a positive integer or distinguish undefined from numeric zero before applying the comparison.

There was a problem hiding this comment.
When a carried accomplishment names a directory-qualified artifact such as src/index.ts, this unconditional basename comparison marks it verified if the ledger contains any different index.ts (for example, test/index.ts). Because verified carry status is subsequently append-only, the incorrect fact survives every later compaction and can direct the continuing agent to the wrong deliverable. Use basename fallback only for tokens that do not already contain a directory component.

CommonMark 0.30 fenced code blocks backtick fence info string may not contain backticks
💡 Result:
In CommonMark 0.30, an info string following a backtick-fenced code block is explicitly restricted from containing backtick characters [1][2]. The specification mandates this restriction to prevent potential parsing errors where inline code could be incorrectly interpreted as the beginning of a new fenced code block [1][2]. This rule applies specifically to backtick fences [1][2]. If a code block uses tilde fences (~~~), the info string may contain backtick characters [3]. The info string itself is defined as the text following the code fence on the same line, after being trimmed of leading and trailing spaces or tabs [1][2].

…ation exemption and source hygiene Third-pass review across independent reviewers. 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).

Third-pass multi-model review — consensus table and dispositionsThree additional independent reviewers went over this branch end-to-end (full diff, callers, consumers, test suites). Their findings are normalized and de-duplicated below, then verified against the current head rather than the head each was written against. An earlier reviewer's findings and the ~166 automated-bot comments were dispositioned in previous rounds and are not re-litigated here. Coverage caveat, stated up frontReviewer A's run was cut off by a tool timeout before it emitted its report. Its transcript shows it completed the review passes it had planned (session core, compaction, run loop, truncation, CLI, config, tests) and ran the suites green, but the final report step never produced output, so it contributes no findings — that is a gap in coverage, not a clean bill of health. A re-run was requested and had not returned when this was posted. Reviewers B and C produced complete reports. Reviewer A's column below is marked Comparison tableLegend: X = raised by that reviewer · prev = already found and dispositioned in an earlier round · verdicts are against the current head.
New findings this round: 8 (rows 4, 6, 7, 10, 18, 19, 21, 23) — the other 15 were already found and dispositioned. Of the 8: 3 confirmed and fixed, 3 confirmed and deferred, 2 false positives. Plus 1 confirmed issue found during verification (row 24). Overall verdicts as given
Both verdicts were reached against an earlier head. Reviewer B's stated blocker (row 1) does not reproduce here — that suite is green — and its two other blocking items (rows 2 and 3) were already fixed. Reviewer C's five major items resolve to: three already fixed or dispositioned (rows 3, 8, 9), one fixed in this push (row 4), and one partially fixed with a documented residual (row 7). What changed in this push
Gates
CaveatsRow 7's residual needs verification against the provider that originally motivated the tool stubs; that is a live compatibility question, not something to settle by reading code. Row 6 changes when a safety detector fires and should be driven by validation data rather than review preference. The gate test added for row 4 mirrors the gate expression rather than importing it — the existing follow-up to extract that predicate into a directly testable form still stands, and until it is done this test documents intent more than it prevents regression. |

Remove abort listeners after successful compaction
Every successful compaction adds a one-shot listener to the same session-lifetime AbortSignal, but the listener is removed only if that signal eventually aborts. Long sessions that compact repeatedly therefore retain one closure per completed compaction and can cross the runtime's listener-warning threshold well before the session ends. Keep the callback reference and remove it on every normal/error return once compactionAttempts has been cleaned up.
Distinguish manual and reactive compaction triggers
input.auto identifies whether compaction was automatic, not whether it came from proactive overflow detection or reactive provider recovery. The manual summarize endpoint passes auto: false, so every user-requested compaction is recorded as error_recovery; conversely, the reactive overflow path creates an automatic marker and is recorded as overflow_detection. This corrupts the new trigger telemetry in both directions; derive recovery from input.overflow and add a separate manual trigger.

When the HTTP connection times out or resets after the server has accepted the request, this loop calls send() again even though session.prompt is not an enqueue-only operation: the handler awaits SessionPrompt.prompt before returning (server/routes/session.ts:925). If the first generation continues or completes server-side, the retry can append the same user task a second time and run duplicate work. Use an idempotency mechanism, inspect the session before resending, or retry only a truly asynchronous enqueue endpoint.

When snapshot tracking is disabled, commands such as sed -i mutate files without producing a patch part, but this unconditional sed allowlist entry classifies them as read-only. A previously successful verification therefore remains ordered after the stale lastMutationSeq; after the configured compaction and idle-turn thresholds, idle-done can issue a challenge that incorrectly claims no actions occurred after verification. Account for mutating flags/forms instead of classifying solely by command head.

When run --continue, run --session, or --fork resumes a session and supplies a new task, run mode still selects the session's very first user message here. After compaction, that old request is injected as authoritative over the summary and the current prompt, so an agent can be redirected back to a completed or conflicting task. Select the task that began the current run invocation, or at least the latest substantive user instruction for resumed sessions.

When the harness aborts before any step-finish event—for example, max-turn enforcement fires on the first step-start, or prompt enqueue fails—lastFinishReason remains undefined, yet this fallback reports why_model_stopped="stop". The resulting dual-attribution record falsely claims an ordinary model stop even though the model never supplied a finish reason, skewing termination analysis. Add an unknown/none model-stop value rather than mapping every absent or abnormal reason to stop.

Closes #1170
Type of change
What does this PR do?
Evidence-driven reliability improvements to the agent run harness — the loop that decides when a session compacts, when it terminates, how tool output is truncated, and how a
runinvocation reports what actually happened. These were derived from analyzing a corpus of failed/lost agent sessions and grouped into two waves:Wave 1 — structural fixes (summarizer integrity, truncation, id sanitation, honest accounting)
compaction.ts: the post-compaction continue-message now carriesformat/tools/system/variantlike the normal replay branch, so auto-compaction no longer silently widens the permission surface. The summarizer is called with explicittoolChoice: "none"plus an empty-summary retry-once-then-error guard, which prevents post-compaction amnesia caused by tool-call-shaped summaries.llm.ts: skip stub-tool injection when a request declares zero real tools (summarizer fallback path).truncate.ts/truncation.ts: bash output now middle-truncates (1/3 head + 2/3 tail) via a sharedtruncate-core.ts, so both leading first-errors and trailing verdict lines survive; the two near-duplicate truncation modules were deduped onto one core.processor.ts/message-v2.ts: deterministic sanitation of malformed (non-string) tool-call ids, with atomic call/result pair aliasing at ingestion and replay.run.ts:turnCountnow excludes compaction-machinery steps; error serialization is never an empty{}; the process exits nonzero on fatal abort; provider 5xx/timeout gets a bounded, logged retry; run output carries dual-attribution termination fields (why_model_stopped/why_harness_stopped).Wave 2 — core-loop fixes (termination path, task pinning, facts ledger, starvation breaker, nudge arbiter)
session/termination.ts+processor.ts+cli/cmd/idle-done.ts: explicitDONE-token termination (the harness no longer trusts a bare provider finish-stop as "done"); a run-mode-only idle-done fallback with build-after-last-write ordering and a one-shot confirm-DONE challenge (recursion-guarded); adone_reasonfield is now emitted on every run.session/prompt.ts+compaction.ts: the original task instruction is now pinned verbatim through every compaction cycle (mode-aware selection between CLI run-mode and interactive sessions, a dynamic size cap with a livelock guard, and a deterministic "contract card" of extracted literals) — this stops the agent losing or hallucinating literal task details (table names, file paths) once the task itself has scrolled out of the summarized history.compaction.ts: a deterministic, append-only corroborated-facts ledger carried across continue-messages, plus first-person summary framing.session/starvation.ts+session/nudge.ts: a write-starvation circuit breaker (annotate-only by default, config-armable), repeat-signature loop detection, a doom-loop guard, and a single-directive nudge arbiter that resolves conflicts between termination, breaker, and budget nudges by explicit precedence instead of whichever fires last.packages/coreconfig schema: all of the above thresholds (starvation breaker mode/limits, idle-done gating, task-pin sizing) are config-exposed knobs with documented default provenance, not hardcoded constants.Also included: a proactive overflow-estimation fix (the overflow check now accounts for tool output appended since the last recorded token usage, so compaction triggers before a request bounces off the context wall instead of after) and a small addition to the builder agent's prompt — a mandatory finish protocol (re-check the task's literal contract, run a final build so the manifest reflects every change, and stop exploring/commit when turns are running low).
Wave 3 — context estimator safety margin, per-tool-result dispatch cap, run-mode default
compaction.ts: the overflow check now triggers against an effective context limit (base * context_safety_fraction, default 0.65, config-exposed ascompaction.context_safety_fraction/ envALTIMATE_CONTEXT_SAFETY_FRACTION, with a 4000-token floor) rather than the raw declared limit. The char-based token estimator undercounts real tokenization of dense, structured tool output by a material margin, and compaction previously fired too late to prevent an actual provider-side context-overflow error on that class of content; the safety margin absorbs the worst observed undercount.tool-result-cap.ts: a hard dispatch-time cap on every individual tool result (min(configured dispatch_max_tokens, byte-derived cap, 15% of effective limit), with middle truncation and long-line chunking), enforced inprocessor.tsbefore persistence. This closes a bypass where a single oversized tool result (e.g. one large query result set) could jump a small conversation past the context wall in one step, before the overflow check on the next turn ever ran.run.ts+ newrun/run-mode.ts: therunCLI command now impliesALTIMATE_RUN_MODE=1by default (an explicit0/falseis preserved as an opt-out), so any external driver invokingrungets the run-mode termination semantics without needing to set the environment variable itself. Interactive/TUI behavior is unchanged.config.ts: adds thecompaction.context_safety_fractionandtool_output.dispatch_max_tokensschema keys.Interactive TUI behavior is unchanged — all of the run-mode-specific behavior (idle-done fallback, task-pin mode selection, the Wave 3 run-mode default) is gated on the existing run-mode/non-interactive signal and was verified not to fire in interactive sessions.
Pre-PR adversarial review: before opening this PR, the full changeset went through an adversarial review pass looking specifically for correctness edge cases in the new termination/compaction/idle-done logic. That review found 5 high-severity issues, all fixed here: a termination false-positive (the
DONEdetector could fire on a code-fenced, inline, quoted, or indented occurrence of the token rather than requiring a standalone final line); a livelock at the task-pin/compaction threshold boundary (the pin budget and the overflow check computed their effective limits independently and could disagree at the edge); the idle-done fallback not honoring an explicit opt-out; a challenge-send failure being silently swallowed instead of propagating as fatal; and afitHeadbudget calculation that didn't share the same effective-limit path as the rest of compaction. 6 additional medium/low findings from the same review were also fixed directly. 7 remaining deferred medium-severity findings — judged non-blocking for this PR — are tracked in.github/meta/harness-review-followups.md. This pass also included a sweep of code comments to remove internal-process references (planning-document shorthand, corpus statistics) that had leaked into shipped source comments; nothing in the sweep changed behavior.How did you verify your code works?

Note
High Risk
Changes core session termination, compaction, and the
runevent loop (including mid-run abort and retries), with run-mode-only vs interactive gating that must stay correct to avoid false stops or duplicate prompts.Overview
This PR hardens the headless
runharness and the session loop so long tasks can compact, terminate, and report outcomes reliably instead of spinning, false-completing, or dying on context overflow.runcommand now defaults run mode (ALTIMATE_RUN_MODE), tracks turns excluding compaction machinery, emitswhy_model_stopped/why_harness_stopped/done_reason, retries provider 5xx/timeouts with bounded backoff, exits nonzero on fatal abort, and adds a run-mode-only idle-done path: after green verify strictly after the last mutation plus post-compaction idle turns, it issues a one-shot confirm-DONE challenge via the nudge arbiter and re-subscribes to events.Termination centers on an explicit
DONEtoken contract (SessionTermination): barefinishReason: stopis not treated as completion; explicit DONE can end the session even when overflow would otherwise trigger compaction. Post-compaction continue messages preserve format/tools/system/variant, append a corroborated state ledger and summary carry anchors, and inject a single system directive throughNudgeArbiter(termination beats starvation beats budget).Compaction gains a shared
context_safety_fractionoverflow threshold (estimate inflation vs raw provider usage),fitHeadtruncation before summarize, task pin budgeting with livelock halving, empty-summary retry-then-error,toolChoice: "none"on the summarizer, and a circuit breaker that returnsstopinstead of hot-spinning after too many attempts.Processor changes add deterministic tool-call ID sanitation (ingest + replay), a per-tool-result dispatch token cap, and
SessionStarvation(annotate by default; armed only in run mode): write-starvation breaker, repeat-signature and doom-loop escalation (nudge → status-check → hard stop), with legacy permission-based doom loop kept when not armed.Config (V1/V2 + migration) exposes the new knobs (
dispatch_max_tokens, compaction ledger/pin keys,experimental.starvation_breaker); telemetry adds compaction-head-truncated and starvation-breaker events.
