Reconcile never rewrites the baseline; only rebaseline (compaction) and
initialize (first turn) produce baseline text. The durable Applied record
tracks what the model was last told, per source.
- Incompatible stored values re-announce the source baseline as an update
instead of forcing a full replacement
- Sources removed without removal text retain the model's belief silently;
entries self-clean at the next rebaseline
- Rebaseline restates unobservable sources from their last-applied values
instead of blocking; ReplacementBlocked and ReplacementReady are gone
- Rename Snapshot to Applied and Generation to Baseline {text, applied}
Drains now uniformly start one tick after wake or run, removing the
ready-deferred release that ran the first drain synchronously inside
the caller. The synchronous start was observable only by tests that
asserted state immediately after fire-and-forget calls, coupling them
to scheduler internals; those tests now synchronize explicitly through
session.wait or stream-start signals.
Share one insertInitial path between initialize and prepare, and
document the runner's ordering constraint: epoch initialization runs
before promotion so a blocked System Context leaves prompts pending,
while reconciliation runs after promotion so ContextUpdated messages
sequence after promoted input.
One fiber now owns each execution (busy period) and consumes coalesced
doorbell wakes as a loop condition, replacing per-drain fiber chaining
with owner reassignment and entry reuse. Initial starts stay synchronous
so a prompt's wake reaches the provider in the same tick; successor
starts defer one tick so failing self-waking executions cannot grow the
stack.
Remove the steer promotion cutoff: a turn boundary now promotes every
steer pending at promotion time instead of snapshotting the inbox at a
captured sequence, so late-arriving steers ride along into the turn.
Delete legacy projected-prompt synthesis from projectPrompted. The
event-sourced session input migration wiped pre-inbox event history,
so every Prompted event follows an admitted inbox row and a missing or
divergent row on replay is an invariant violation.
Inline the prompt equivalence predicate and update tests that seeded
history with bare Prompted events to publish PromptAdmitted first.
Restructure runner turn settlement: replace TurnTransitionError defect
control flow with tagged turn results and a plain restart loop, name the
settlement evidence, and merge duplicated interrupt branches.
Split settled tool-fiber failures: tool implementation defects keep
surfacing as model-visible tool errors and the turn continues, while
typed ToolOutputStore errors now fail the assistant and the drain
instead of being silently absorbed.

- V2 tool execute hooks: add `ctx.tool.execute.before/after` plugin API,
core ToolHooks service, and registry wiring so hosted/local tool calls
run registered before/after hooks; provider-executed calls are excluded.
- Session synthetic endpoint: add `POST /api/session/:sessionID/synthetic`
with text/description/metadata plus regenerated Promise/Effect/JS client
surfaces.
- SessionInstructions service: read tool discovers nearby AGENTS.md walking
up to the Location root (exclusive) and injects them as durable synthetic
instructions, with lazy history dedup of prior claims.
- to-llm-message: stop forwarding synthetic message metadata to the model so
bookkeeping annotations stay model-hidden.
- schema changelog entry for synthetic metadata and the metadata leak fix.
Add SessionTitle service that generates a session title from the
session's sole user message via the customizable "title" agent, then
renames the session. Runs once per session, gated on durable history
having exactly one user message (no default-title string comparison).
Wire it into SessionRunner as a background fork after the first turn's
prompt promotion makes the user message visible; forking before
promotion caused the first-message lookup to see zero rows and silently
no-op.
