Doc	Fix
session-state.md	3→5 operations, op→operation param fix, added return value docs
slack.md	Missing channel_overrides/user_overrides config fields
sqlite-migration.md	Missing webhooks/vault crates, wrong startup sequence path, incomplete table lists
streaming.md	Missing ProviderRaw/ReasoningDelta StreamEvent variants, 7 new RunnerEvent→WebSocket mappings, wrong code paths

Greptile Summary

This PR audits and corrects four stale documentation files against the current source, updating session-state.md (new delete/clear ops, operation param), slack.md (missing channel_overrides/user_overrides fields), sqlite-migration.md (missing webhooks/vault crates, corrected startup path), and streaming.md (new StreamEvent variants, expanded RunnerEvent→WebSocket table, corrected file paths). All code-level claims were verified against the actual Rust source and match. Two minor inaccuracies remain: the moltis-sessions migration count is off by one, and two stale server.rs references in sqlite-migration.md were not updated alongside the one that was corrected.

Confidence Score: 5/5

Safe to merge — documentation-only PR with accurate content; two minor inaccuracies are easy cleanup.

All code-level claims were verified against live source: StreamEvent variants, RunnerEvent variants, session_state operation names and return shapes, migration startup sequence, and file paths all match. The only issues are a sessions migration count off by one (8 vs 9) and two stale server.rs references left behind — both P2 doc accuracy issues that don't affect any runtime behaviour.

docs/src/sqlite-migration.md — sessions migration count and two residual server.rs references

Important Files Changed

Filename	Overview
docs/src/session-state.md	Adds delete/clear operations, renames op→operation, and documents return shapes — all verified accurate against crates/tools/src/session_state.rs and crates/sessions/src/state_store.rs.
docs/src/slack.md	Adds channel_overrides and user_overrides to the config table with matching TOML examples; changes are straightforward and consistent with existing config patterns.
docs/src/sqlite-migration.md	Adds webhooks/vault crates, corrects startup sequence path to prepare_core.rs, expands migration table — but sessions migration count says "+8" when the filesystem has 9 additional files, and two stale server.rs references remain uncorrected.
docs/src/streaming.md	Adds ProviderRaw/ReasoningDelta variants (verified in model.rs), corrects runner path to runner/streaming.rs, adds 7 new RunnerEvent→WebSocket mappings (all verified in helpers.rs), and updates example signature to Vec<ChatMessage> (matches trait).

   Stale server.rs reference — inconsistent with correction above

   The Startup Sequence section was updated in this PR to reference prepare_core.rs, but this line in "Adding Tables to a New Crate" and the DON'T entry on line 285 ("Skip the dependency order in \server.rs`") still say server.rs`. Readers following the how-to guide will look in the wrong place.

   Line 285 also needs updating:

   - Skip the dependency order in `prepare_core.rs`
