In long-running agent workflows with repeated context compaction, empirical gateway ablations across 132 real sessions revealed that standard boundary compliance remains robust, while semantic drift can occur when model-generated summaries rephrase literal approval phrases and action conditions.
This change converges PR #8114 into a clean built-in summary prompt enhancement:
- Replaces regex extraction, tag elevation, and heuristic revocation with an extended built-in DeerFlow summary prompt (_DEERFLOW_SUMMARY_PROMPT).
- Instructs the summarizer to faithfully record active user requirements, literal approval phrases, permitted actions, and later explicit revisions without paraphrasing.
- Treats summary text strictly as historical data, fully preserving the security boundary and control/data plane separation of DurableContextMiddleware.
- Unifies automatic and manual compaction factory paths to select the built-in template when unconfigured, while preserving explicit summary_prompt precedence.
- Adds comprehensive sync/async unit tests covering built-in and custom templates.

* docs: turn README into an index and move reference detail to docs/guide
The README had grown to 393 KB because every change appended its notes there. The text moves verbatim into 18 topic guides under docs/guide/; only headings are re-leveled and relative links re-pointed. The README keeps the introduction, a quick start and a guide index. Contributor test notes move to CONTRIBUTING.md.
* docs: send user docs to topic guides and budget the root README
The rule 'update README.md for user-facing changes' is what grew the README. Guidance now points to docs/guide/, and check_agent_guidance.py fails when the root README exceeds 16 KiB (AG003).
* chore: remove unreferenced screenshots and finished plan notes
pr-build/ holds two PR screenshots (3 MB) from #1986. plans/ holds the plan for the merged #4049. docs/SKILL_NAME_CONFLICT_FIX.md is a February change note. Nothing references them.
* docs: route always-loaded AGENTS.md files to scoped guides
* docs(agents): cut scoped guides to scope, verify, traps, decisions
Each AGENTS.md keeps four kinds of content: the scope of the directory, the
verification commands, traps a local test run does not show, and decisions the
code cannot state. Values, field lists, function inventories, test names, issue
numbers and history are deleted, because the code, the tests and git state them.
Search and fetch providers share one community guide. Four guides with no
remaining content are removed. The size check now allows 6 KiB per file (hard
limit 8 KiB) and 24 KiB per chain (hard limit 32 KiB).
* style: format frontend guide table and guidance test imports
