feat: memory block off the critical path, and per-thread tool_search and context options - #8599
Part of tinyhumansai/chottu-core#712, the epic to cut the tokens and seconds that tool calls and turns cost. Chottu is the first host to use these changes.
Every new behaviour defaults to today's behaviour. Per-thread options are pinned on the thread when it is created, so existing threads keep what they started with.
[agent.tool_search] and OPENHUMAN_TOOL_SEARCH_* set promote_found_tools, compact_search_results, collapse_search_results, repair_tool_call_wrapper and max_limit.
The embed API gets AgentSpec/Turn::tool_discovery and Turn::tool_discovery_force, which applies options to an existing thread.
The options are pinned on the thread and carried across compaction.
tool_search results are exempt from TinyJuice reshaping.
[search] adds compact_results and contents_max_chars. The embed API gets matching AgentSpec/Turn setters. The replay pin survives compaction. feat(webview): browser-like permission management for embedded apps (#713) #721 fixes the driver, which dropped the session's RunConfig options before the run loop read them.
Read beliefs and learnings concurrently, log elapsed_ms for each render,
bound a generation start's wait with [memory] memory_block_deadline_ms
(deferred renders land in a process-wide store taken by the next
generation start), and add OpenHumanSessionHost::prewarm_memory_block and
embed Agent::prewarm_memory_block plus MemoryBinding::memory_block_deadline.

Takes tool sizes on ToolCompleted/TurnObservation::Tool and the discovery
policy options (promote, compact, collapse, tool_call repair). The tool
completion test literals gain input_bytes: None.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds promote_found_tools, compact_search_results, collapse_search_results,
repair_tool_call_wrapper and max_limit to [agent].tool_search (with env
overrides), mapped onto the harness ToolDiscoveryPolicy. A session takes the
four prompt-shaping options from the config when it creates a thread, records
them on the thread's first transcript row when they differ from today's, and
reads them back on resume, so a thread keeps the behaviour it started with.
openhuman-embed gains AgentSpec::tool_discovery and Turn::tool_discovery
(ToolDiscoveryOptions) and documents the tool sizes on observations.

…ng the memory block
prewarm_memory_block built its session without the embedder's route and
model, so a hosted-route-only embedder answered BACKEND_UNAVAILABLE. It now
applies them through apply_turn_overrides, as compact_thread does.

…ng replay and tool pruning
Adds [context] keep_recent_tokens, tool_result_max_age_turns,
tool_result_exempt_tools, replay_reasoning and prune_retired_tools with env
overlays. Expiry and reasoning replay are pinned on each thread like the
tool_search options (replay_pin.rs); prune_retired_tools chains onto the
session builder and the granted snapshot names its deferred catalogue as
offered. AgentSpec and Turn gain matching setters over ContextOverrides.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds [search] compact_results (RenderOptions::compact via render_*_with) and
contents_max_chars (ProviderConfig.contents_max_chars), both off by default,
with env overlays.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Turn::tool_discovery_force runs the turn with the options and records them on
a later row; the latest record wins. Default behaviour is unchanged.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Agent open, transcript resume, prompt refresh and the memory block each
report their duration and outcome to the turn's observer before the first
model request. A memory block that missed its deadline is Skipped and a
failed read is Failed. SetupPhase and SetupOutcome are re-exported from
openhuman_embed::observe.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Mirrors discovery::carry_forward for the [context] options pinned by
replay_pin, so a thread keeps its result expiry and reasoning replay after
compaction drops the row that recorded them.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
replay_pin::resolve let the config override a pin the rows already record
when the turn prepared the thread's first prompt again (a compacted head).
Mirror the recorded.is_none() guard in discovery::resolve.

…ry options to the turn's run config
The session prepares result_expiry, replay_reasoning and discovery overrides on the
RunConfig it gives its driver, but the driver builds a fresh RunConfig for the turn,
so the harness read them empty and never expired old tool results.
Co-authored-by: Medulla <medulla@tinyhumans.ai>
…ards for epic 712
Split run_context_tests.rs below the 750-line limit, record ownership for the
memory-block READY static, and give the config schema its own ReasoningReplay
enum (same TOML/env names) that converts to the harness type where replay
options are built, so config no longer re-exports a TinyAgents type. The embed
API (openhuman_embed::ReasoningReplay) is unchanged.

Runs belief and learning reads concurrently and adds timed test fixtures. Documents memory-block behavior and registers the ready-block store.
Search configuration and rendering
Layer / File(s)
Summary
Search settings and provider configuration crates/openhuman-core/src/config/schema/tools/search.rs, crates/openhuman-core/src/config/schema/load/env_overlay/search.rs, crates/openhuman-core/src/modules/search/*, crates/openhuman-core/src/modules/registry/records_search.rs, vendor/tinysearch
Adds compact-rendering and page-content limits, passes the content limit to provider configuration, and updates TinySearch release assets and the vendored reference.
Adds explicit rendering options and passes the compact-results setting to successful search responses. Tests cover compact output and duplicate citations.
Resolve memory-cache isolation, deletion handling and background-work limits before merging. Configured deadlines can also disappear, and some thread settings fail to persist or apply consistently. These issues can resend erased or previous-backend memory, prolong setup, and change conversation behavior unexpectedly.

tests
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The new tests in this diff are substantive: they assert on observable behaviour (recorded metadata on the first fresh row, carry-forward across compaction, deadline/deferred/prewarm paths, env-overlay parsing, compaction tail sizes, tool_search exemption) and would fail if the corresponding behaviour regressed. I found no test that asserts only on mocks or cannot fail, and no new branch left uncovered that I could pin to a concrete input. One gap worth noting but not reportable as a defect: the `force_pin` path in `discovery::resolve` is exercised only at the unit level in `pin_tests.rs`, not end-to-end through a session turn, so the claim that a forced turn records on a later row is pinned by unit tests rather than a wire test. _The code index is behind this pull request (indexed at `09f5e69c55f4`), so retrieved context may be out of date._

description
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The description matches the diff: it names the memory-block deadline and prewarm, the tool_search and context options with their env vars and embed setters, the pinning across compaction, the Setup observations, the TinyJuice exemption, the tinysearch re-pin and the CI guards, and every one of those appears in the change. I found no description defect worth reporting. _The code index is behind this pull request (indexed at `09f5e69c55f4`), so retrieved context may be out of date._

Addressed in the follow-up #8600 (this PR has merged). It drops ready blocks and voids in-flight renders on memory writes, erasure and engine/credential changes, orders renders so an older one cannot overwrite a newer block, and caps background renders at 8 with a 60s deadline. Left open until that PR merges.

Invalidate cached blocks when memory is erased
When a prewarm or deferred render has populated READY and the user subsequently calls memory_forget or memory_erase_all, those operations invalidate only lifecycle::prefetch (see memory::ops::forget and erase_all); nothing evicts this new cache. The next new thread or generation therefore takes the pre-deletion block here without reading the engine, allowing erased facts to enter a fresh persisted prompt for up to an hour after deletion. Include ready blocks and in-flight renders in the existing deletion invalidation/fencing path.

Assert the recorded discovery options after resume.
The test counts tool_discovery keys but does not check their values. An in-place replacement with the current configuration would still pass. Assert that the recorded options equal DiscoveryOptions::from_config(&no_promotion()) before and after resume.

forced update coincides with compaction, ensuring the forced pin wins on later
turns. Preserve stored rows on ordinary turns; only change the ordering for

prepare_prefix_for_turn and discovery::resolve to preserve the thread’s
established discovery and replay settings across a reset, even when its prefix
is unfrozen and has no pin. Ensure the next turn does not silently adopt newly

existing settings through the reset.

@crates/openhuman-core/src/agent/session_host/runtime_session/memory_block_ready.rs:
- Around line 82-83: Update the ready-block cache flow around ready_key and take
so memory deletion invalidates waiting blocks and prevents renders started
before the deletion from repopulating the cache afterward. Preserve the existing
ready-block behavior for renders that occur after deletion, using the
established memory-deletion and cache synchronization mechanisms.
- Around line 43-48: Update the next-generation compaction path associated with
prewarm_memory_block to consume the prewarmed block matching the session’s
memory identity and place it in the successor prefix instead of rendering memory
again. Preserve the existing rendering path when no matching prewarmed block is
available.
- Around line 105-110: Bound deferred memory rendering in the spawn_memory_work
path: limit how many cache-miss renders may be admitted concurrently and ensure
each admitted render has a deadline, including the prelude.render_in call. Reuse
existing task-limit and timeout mechanisms where available; preserve the current
behavior for admitted renders.
- Around line 145-150: Update ready_key and ReadyKey so cached blocks are scoped
to the memory backend endpoint and account as well as the existing workspace,
identity, and token limit. Ensure the existing engine invalidation path also
clears ready blocks when the memory source changes, so blocks from the previous
backend or account cannot be reused.
- Line 188: Update the storage path around entries.insert so an older render
cannot replace a newer block for the same key. Order renders per key or use an
established freshness/version check before storing, preserving the newest memory
state when renders overlap.

- Around line 242-244: Update the MemoryBlock setup flow around
SetupPhase::MemoryBlock and block_for_generation to distinguish a deferred cold
render from an actual generation start. Retain the deferred block until
generation begins, and only consume it at that point so the next normal turn
does not open an extra generation or alter the cached prefix.

- Around line 12-21: Update reported so cancellation or deadline interruption
also reports the setup phase with elapsed time before the host’s terminal

Review comments at @crates/openhuman-core/src/agent/tinyagents/discovery/mod.rs:
- Around line 111-112: Update the turn policy construction so `policy.max_limit`
uses the search cap captured for the current session rather than the shared
`settings.max_limit` slot, which another agent can overwrite. Keep
`policy.default_limit` clamped to that same session-specific cap.
Review comments at @crates/openhuman-core/src/agent/tinyagents/discovery/pin.rs:
- Around line 157-159: Update carry_forward so
DiscoveryOptions::recorded_in(rows) does not let an older retained system row
suppress the latest forced discovery pin. Identify the latest forced pin from
the available transcript and preserve it through compaction, while retaining the

Review comments at @crates/openhuman-core/src/search/tools.rs:
- Line 316: Update the rendering option passed to render_options in the direct
tool so it uses the effective per-call search configuration rather than the
spawn-time config; preserve host-pinned settings when resolving that
configuration.
Review comments at @crates/openhuman-embed/src/agent/build.rs:
- Around line 181-183: Update the memory deadline assignment in the binding
configuration flow so selecting only a memory identity preserves the runtime’s
configured deadline. Replace `config.memory.memory_block_deadline_ms` only when
`binding.memory_block_deadline_timeout()` returns an explicit deadline, keeping
the existing millisecond conversion and overflow behavior.
Review comments at @crates/openhuman-embed/src/turn.rs:
- Around line 469-474: Update the turn setup around keep_recent_tokens so the
value is recorded when a thread is created and restored for later turns,
preventing agent defaults or overrides on an existing thread from changing that
thread’s compaction tail.

Use the prewarmed block during compaction.
When compaction opens the next generation, it renders memory again instead of using the prewarmed block. A slow read delays compaction while it holds the session lock. Consume the matching prewarmed block and put it in the successor prefix.

Bound deferred memory renders.
When memory reads are slow, each cache miss starts another detached render. Repeated starts can accumulate tasks and engine requests after turns continue, exhausting resources or adding load to the backend. Limit admitted renders and give background work a deadline.

Prevent older renders from replacing newer blocks.
If overlapping renders read different memory states, the older render can finish last and replace the newer block. The next generation can then use stale memory for its entire lifetime. Preserve freshness when storing results, for example by ordering renders per key.

Keep deferred blocks until a generation starts.
If a cold render finishes after its deadline, the next normal turn can consume it because the recorded prefix has no block. The runtime then opens an extra generation and changes the cached prefix. Distinguish a deferred cold render from a genuine generation start before consuming the block.

…ackground renders
A memory block rendered ahead of a generation (prewarm or a render that
outlasted its deadline) waited in the ready store untouched by memory writes,
erasure, or an engine or credential change, so erased or changed facts could
reach a fresh prompt for up to an hour.
- memory writes and erasure drop the workspace's ready blocks and void its
renders in flight; an engine or credential change does so for all
- a render may store its block only if no invalidation ran since it started,
and never over a block from a render that started after it
- renders left running past their deadline are capped at 8 and abandoned
after 60s
- process-statics records for READY and the new render-slot counter
