- seal() now runs before the final dispose close() and bumps the disk
epoch: work an event handler enqueues while dispose awaits the closing
tail is superseded, and an already-running fenced or authoritative
rewrite fails its commit guard at the rename fence instead of
publishing over a file a revival reopened.
- The authoritative repair path resets the disk tail itself, escaping the
close() serialization, and would atomically publish the emptied entry
list; it now no-ops once sealed and commit guards also check the seal.
- Execution-time gates cover the queued title persist and fenced rewrite
callbacks; setSessionName/appendCustomEntry attempted by a handler that
outlives dispose are dropped and covered by the seal regression, and a
failed atomic batch across the seal can no longer truncate the file.
- AgentLifecycleManager.park() resolves as soon as dispose() returns, so
ensureLive() may reopen the same JSONL through a new manager while a
timed-out event handler still holds the old one; a late append reopened
a second writer on that file and the deferred finalize then closed it.
- A post-release rewrite was worse: it persisted the emptied entry list,
truncating the transcript on disk.
- releaseRetainedEntries() now seals the manager: appends, title changes,
and rewrites become dropped no-ops and the append writer is closed, so
the deferred dispose pass is in-memory only and can never touch the file.
- File-backed regression: dispose on the drain deadline, revive the JSONL
immediately, unpark the late handler, and prove the file is byte-stable
and the revival writer owns it exclusively.
- The dispose drain deadline does not cancel in-flight event handlers: one
parked in a slow extension hook resumed after close/release, reopened the
append writer for its late persist, and repopulated the released state.
- Track whether the drain settled; on deadline, redo the final close +
release once the pipeline genuinely settles (hook runtime is bounded by
the extension runner).
- Expose drainTimeoutMs on AgentSessionDisposeOptions for bounded teardown
paths and deterministic coverage of the deadline branch.
agent-core dispatches the session's event subscriber fire-and-forget (agent.ts #emit), so a message_end/agent_end handler can still be awaiting extension/subscriber/maintenance work — and its sessionManager/agent.state append — after agent.waitForIdle() resolves. The earlier settle waited only on the core run, so a late handler could append the finished message/entries back into the disposed session and re-pin the transcript.
Track every #handleAgentEvent dispatch in #inFlightEventHandlers and drain it (alongside agent.waitForIdle) inside the bounded settle before reset/clear/release. Added a regression test using a real extension whose message_end hook blocks before persistence, asserting dispose does not release memory until the in-flight handler settles.
dispose() only *signalled* the agent loop via abort(); it never awaited the run, so a mid-turn dispose (Ctrl-C/timeout/hard-killed subagent) could let the loop unwind after the release ran — its response/SSE interceptors re-recording wire frames into rawSseDebugBuffer and its terminal message re-appending to agent.state.messages, repopulating the disposed session with exactly the retained state the release drops.
Detach the response/SSE interceptors and await a bounded agent.waitForIdle() before the reset/clear so it lands on a quiescent session. Added a deterministic regression test that gates the active turn and asserts dispose blocks on it before clearing.
Disposed sessions remained reachable through lifecycle reviver closures. Agent.reset() cleared the live message array but left AppendOnlyContextManager attached, retaining its normalized provider transcript and stable prompt/tool prefix.
Detach the append-only manager during terminal disposal and extend the memory-release regression test to cover that second transcript copy.
Keep-alive subagents are handed to AgentLifecycleManager.adopt, which stores
their reviver closure in the process-global #adopted map. The closure is
defined inside runSubagent's scope, which also captures the live AgentSession
(extension-runner callbacks, buildSubagentSessionOptions), so its lexical
environment pins the whole session graph. park() disposes and detaches the
session but leaves the adoption record indefinitely, and #doDispose never
dropped the in-memory transcript, session-manager entries, or the raw-SSE
debug buffer (whose trimmed records retain slice() views of full wire frames),
so every completed subagent's heavy state leaked for the process lifetime.
dispose() is terminal and every revival path reopens from disk, so #doDispose
now sheds retained conversation memory via agent.reset(),
RawSseDebugBuffer.clear(), and SessionManager.releaseRetainedEntries(). The
adoption record can still reference the session, but only as a husk.
Fixes#8003
Harness-initiated session aborts previously cancelled compaction before the handoff reason was recorded. The handoff catch then saw only an aborted signal and replaced the harness reason with "Handoff cancelled".
Abort the handoff first with the session reason, forward caller-signal reasons, and reserve "Handoff cancelled" for direct or unreasoned cancellation. Add a regression test for an in-flight handoff aborted through AgentSession.abort.
Fixes#7993
- Separated deterministic replacement generation, placeholder derivation,
placeholder-range scanning and message-tree transforms out of the 2647-line
module; obfuscator.ts now holds the types and SecretObfuscator.
- ephemeralPlaceholderKey stays a single instance and both global regexes stay
beside the code that resets their lastIndex, so placeholder stability and
the security argument in the moved comments are preserved verbatim.
- Repointed every importer at the real modules rather than leaving a re-export
shim; the public ./secrets barrel exports the same 15 names as before.
A cooldown-expiry model revert runs at a turn boundary. The user-prompt
path reverts then re-checks accumulated context against the restored
model via runPrePromptCompactionIfNeeded, but the automatic
agent.continue() path (#scheduleAgentContinue) reverted and issued the
next request with no such check. When a transient failure had fallen
back to a larger-window model and the conversation then grew past the
original model's window, restoring the primary once its cooldown expired
sent a predictably oversized request to the smaller model.
maybeRestoreRetryFallbackPrimary now reports whether it actually
switched, and the auto-continue path runs the same post-revert
context-fit maintenance (compaction/promotion) the prompt path already
runs, but only when a revert occurred.
Fixes#7952
The per-turn systemPrompt returned by before_agent_start was applied only to the agent state, so any base-prompt rebuild firing in the prompt window (context-overflow compaction/promotion, memory promotion, MCP/RPC tool refresh, hindsight MM-TTL refresh) re-pushed the rebuilt base via setSystemPrompt and silently dropped the override before the request.
SessionTools now tracks the active per-turn override and re-applies it on every base rebuild during the turn, clearing it when the turn ends.
Fixes#7755
- Bounded rewind report recovery to messages created after the active checkpoint.
- Added resumed-context regression coverage for late stale rewind results.
Fixes#7739
The ExtensionAPI getAllTools() wired to session.getAllToolNames(),
returning bare tool-name strings. Upstream @earendil-works/pi-coding-agent
promises ToolInfo[] with sourceInfo, so extensions loaded through the
legacy-pi shim (e.g. gentle-pi) crashed on t.sourceInfo.source at every
session start.
Added SourceInfo/ToolInfo types plus SessionTools.getAllToolInfos(), which
returns { name, description, parameters, sourceInfo } and classifies each
tool as builtin/mcp/sdk/extension. Rewired every getAllTools action site
(interactive, acp, print/rpc, subagent executor) and the example extension.
Fixes#7732
Registered live session resume commands with postmortem handling so a
fatal rejection or exception identifies every recoverable agent before
cleanup. Escaped terminal control characters in recovery output.
Reset-window rotation requires account-specific wording; concurrency caps require an actual cap signal; credential removal gated on AuthFailed without UsageLimit so a valid-but-blocked 403 credential is retained.
(cherry picked from commit 2f72752c2586352a4f7e9e814af1cdb0cf192af4)
Made text replay safety depend on whether the active output sink has committed streamed text.
Kept tool calls, images, and server tools replay-unsafe while covering text and JSON print policies plus a transient socket-close recovery.
Fixes#7625
Branched session files preserve entry ids, so leaf-id equality alone let a stale /btw answer promote into a different loaded session. Capture the originating session id at /btw start and require it to match at both the controller gate and every branchFromBtw checkpoint.
Fixes#7474
- Passed the authorized leaf through the branch executor and revalidated it before rewriting history.
- Refused promotion during active turns and bounded post-prompt drains.
- Consumed unavailable branch keys while showing pending and refusal state in the panel.
Fixes#7474
Publish terminal daemon completions to the session that started the
process so idle agents can resume without polling hub status.
Persist every unacknowledged generation with a stable completion ID and
immutable snapshot. Replay the collection after reconnect or broker
recovery, and clear each event only after the owning client acknowledges
it.

Hard-coded 'scout' references reached the model even when the scout
agent was disabled via task.disabledAgents or absent from the session
spawn list. Gate every such reference on scout actually being spawnable:
the task tool description, the delegation gates, the plan-mode and
workflowz notices, the glob/grep/ast-grep guidance, and the task
specialization advisory. Prompt shape is otherwise unchanged; only
erroneous references to the unavailable subagent are dropped.
Closes#7313
- Make over-context models selectable in the model picker by graying them instead of disabling them.
- Trigger automatic session compaction with the current model prior to switching when an over-context model is chosen.
Rebuilt advisor runtimes with the rediscovered context files so advisor turns stop evaluating against stale AGENTS.md instructions after /reload-plugins.
Fixes#7258
- Reused the agent's explicit or inherited cache identity for ephemeral side turns.
- Forwarded the same effective key through manual and automatic native compaction.
- Added regression coverage for all three secondary request paths.
Fixes#7218
- Reused the live Codex provider session for WebSocket-first V2 compaction.
- Fell back to SSE V2 on WebSocket transport failure before the existing V1 fallback.
- Propagated the configured WebSocket preference through manual, automatic, and advisor compaction paths.
- Added transport reuse and fallback regression coverage.
Fixes#7198
- Replaced the reactive weekly-only auto-redeem predicate with a pool-wide
planner: an expiry-salvage sweep piggybacks on the 5-minute usage
heartbeat and spends any account's reset that would otherwise expire
within codexResets.salvageHorizonHours, and the blocked-turn path scans
all stored accounts with eligibility built from the exact exhausted
5h/weekly windows (openai/codex#28525), unblocking at the latest reset
among them.
- Made the live 429's parsed unblock timestamp authoritative for the
active account (pre-block snapshots survive cache invalidation via
in-flight adoption and last-good fallback), synthesizing the candidate
when no usable report exists, and overlaying live credit counts from
the dedicated credits route since a stale /wham/usage zero is never
corrected upstream.
- Treated nothing_to_reset, credit_list_failed, and thrown consumes as
non-terminal: the episode key is released and deferred 30 minutes
instead of burying a banked credit; redeemResetCredit now spends the
soonest-expiring credit.
- Added planner unit fixtures plus integration regressions driving the
real triggers end to end, with an injectable per-session coordinator
seam and a sweep settlement handle.
