The legacy system_prompt_composer fragments and its default_system_instructions
wrapper were no longer referenced by any live code path (the main-agent prompt
builder owns composition now). Delete the whole orphaned tree and its test.
Rewrite the main-agent citation contract to a single [n] channel and sync
the orphaned system_prompt_composer surface to match; drop stale
[citation:chunk_id] / <chunk_index> references from dynamic_context and
provider hints. Reuse the shared hybrid search in the deliverables report
(citations omitted for now) and delete the orphaned report KB helper.
Remove the dead eager KnowledgePriorityMiddleware wiring (knowledge_priority
+ stack) and its legacy browse test. Update ADR 0001 to reflect the cutover.
Neither module is imported by any sibling agent package, so neither belongs in
the cross-agent shared kernel:
- checkpointer.py -> app/agents/runtime/checkpointer.py
LangGraph Postgres checkpoint saver. It's cross-agent *runtime infra* wired by
the boundary (app lifespan + anonymous_chat & multi_agent_chat flows), not
agent code. New app/agents/runtime/ layer holds boundary-wired agent infra.
- shared/system_prompt.py + shared/prompts/ -> app/prompts/
The legacy single-agent prompt composer. The live agents don't use it
(main_agent has its own system_prompt/ builder; anonymous_chat builds inline);
its only consumer is new_llm_config_routes for displaying default instructions.
Moved to the existing non-agent prompt domain:
system_prompt.py -> app/prompts/default_system_instructions.py
prompts/ -> app/prompts/system_prompt_composer/
app/agents/shared/ now contains only genuinely cross-agent code: context,
middleware/{compaction,retry_after,dedup_tool_calls}, tools/.
NOTE: get_default_system_instructions() (LLM-config UI) composes from the legacy
library, which differs from what the live agents actually run -- pre-existing
latent staleness, not changed here.
Three live shared leaves discovered while taking stock after slice 7 (all are
consumed by the multi-agent stack and/or live routes, not single-agent-only):
- connector_searchable_types -> shared + shim (multi-agent factory uses it)
- agent_cache -> shared + shim (multi-agent runtime/agent_cache uses it)
- system_prompt + prompts/ (42 .md fragments) -> shared together + shim.
Repointed composer's _PROMPTS_PACKAGE to app.agents.shared.prompts so
importlib.resources fragment loading keeps working; system_prompt's relative
".prompts.composer" import is preserved by moving both as a unit.
Each keeps a re-export shim for the frozen chat_deepagent. After this slice,
new_chat/ holds only the frozen single-agent stack (chat_deepagent, subagents/,
__init__) plus shims.

- Updated `litellm` dependency version from `1.83.4` to `1.83.7`.
- Adjusted `aiohttp` version from `3.13.5` to `3.13.4` in the lock file.
- Implemented `apply_litellm_prompt_caching` in `chat_deepagent.py` to improve prompt caching.
- Added model name resolution logic in `chat_deepagent.py` to ensure correct provider-variant dispatch.
- Enhanced `llm_config.py` to configure prompt caching for various LLM providers.
- Updated tests to verify correct model name forwarding and prompt caching behavior.
- Updated `content_hash` in the `Document` model to remove global uniqueness, allowing identical content across different paths.
- Enhanced `_create_document` function to handle path uniqueness and prevent session-poisoning from `IntegrityError`.
- Added detailed comments for clarity on the changes and their implications.
- Introduced new citation handling in the editor for improved user experience with citation jumps.
- Updated package dependencies in the frontend for better functionality.
