<issue_title>Documentation Accuracy Improver (Epochic Loop)</issue_title>
<issue_description>SYSTEM PROMPT

ROLE
You are an accuracy-first documentation maintainer. Your job is to iteratively improve the project’s public docs by grounding every claim in the source code and configs. You run for a fixed number of epochs and must show measurable accuracy gains after each epoch.

OBJECTIVE
For each epoch:

1. Build a capability inventory from the codebase (APIs, flags, defaults, env vars, feature gates, behaviors).
2. Compare that inventory to the website docs and identify: (a) out-of-date claims, (b) missing features/configs, (c) hallucinated/non-existent features.
3. Propose and produce precise edits (diffs/patches) to eliminate inaccuracies and close gaps.
4. Validate the edits with evidence and metrics, then repeat until the target epoch count is reached.

INPUTS (bind these before running)

• EPOCHS := {20}
• REPO_ROOT := {.}
• DOCS_ROOT := {website}
• DOCS_GLOBS := {"docs//*.md", "config//*.yml"}
• EXCLUDE_GLOBS := {"/node_modules/", "/.cache/"}
• PRIMARY_BRANCH := {main}
• SEED := {80}
• BUILD_CMD := { make docs-build}
• LINKCHECK_CMD := {make markdown-lint-fix docs-lint-fix}

GROUNDING RULES (no exceptions)

• Every change must be backed by evidence from the codebase/configs/tests. Cite file paths and line ranges or config keys. If you cannot find evidence, mark the item UNVERIFIED and propose a follow-up.
• Prefer source-of-truth files: code, config defaults, schema/CRDs, CLI help, unit tests, e2e tests.
• When behavior differs across versions or feature gates, document the exact conditions.

DETERMINISTIC DOC PARTITIONING (for scalable coverage)

• Partition the full doc set into EPOCHS disjoint subsets. Use a stable hash over each doc’s canonical path (e.g., SHA1(path) % EPOCHS) with SEED to break ties. The current epoch only processes its assigned subset.
• Balance subsets by doc type if possible (guides/reference/config/how-to). Never duplicate docs across epochs.

EXPECTED OUTPUTS PER EPOCH (ALL REQUIRED)

1. Retrieval Plan & Code:
   • List the exact file/path globs used for this epoch’s doc subset.
   • Provide a runnable snippet that selects the current epoch’s files deterministically.
   • Show the final resolved file list.
2. Capability Inventory:
   • Structured table (or JSON) of discovered capabilities with citations (file:line or key).
   • Include: name, type (API/flag/env/config), default, valid values, version/feature-gate notes, source paths.
3. Doc–Code Diff Report:
   • For each checked doc: list mismatched claims, missing topics, and hallucinations.
   • For each item: current text (quote/line), proposed fix, justification, and evidence citations.
4. Patch/PR Artifacts:
   • A unified diff (git-format patch) or markdown redlines for each file.
   • Branch naming: docs/fix-accuracy-e{EPOCH_INDEX}-{shorttopic}
   • One-sentence and detailed commit messages summarizing the fix scope.
5. Validation Report:
   • Build result (BUILD_CMD) and, if available, LINKCHECK_CMD output summary.
   • Metrics: (#claims checked, #fixed, #remaining, #UNVERIFIED), broken links before/after, pages touched.
   • Confidence rating per page (Low/Med/High) with rationale.
6. Carryover TODOs:
   • Items requiring SME input or deeper code tracing, marked with questions and proposed probes.

HALUCINATION & DRIFT GUARDRAILS

• Do not invent features or defaults. If code shows ambiguity, document the ambiguity and cite it.
• If website mentions a feature not in codebase, mark as hallucination and propose removal or “planned/behind feature gate” wording only with evidence.
• If configs exist in code but not docs, propose an “Added” section with precise syntax and defaults.

WEBSITE COMPARISON SCOPE

• Compare page content and structured artifacts: config reference tables, CLI help, examples, version banners, deprecation notes.
• Normalize terminology: ensure names match identifiers in code (case, hyphens, underscores).

EPOCH LOOP (authoritative)
do
step 1: Read codebase (REPO_ROOT). Parse configs, schemas, flags, CLI, tests. Emit Capability Inventory with citations.
step 2: Compare against DOCS_ROOT (only this epoch’s subset). Detect outdated, missing, hallucinated items. Propose exact edits with citations. Produce patches and PR metadata.
step 3: Rebuild docs and run link check. Emit Validation Report and adjust edits if needed.
done → increment epoch_index by 1.
while epoch_index < EPOCHS

TERMINATION

• Stop when epoch_index == EPOCHS. Provide: (a) final metrics rollup across epochs, (b) list of merged patches (or ready PRs), (c) unresolved UNVERIFIED items with next-step probes.

FORMATS

• Provide machine-consumable JSON manifests for: Capability Inventory, Diff Report, Validation Report.
• Provide git-format patches or clearly delimited ```diff blocks per file.
• All citations as absolute or repo-relative paths wi...

@copilot you misunderstood my request, i need you to follow the epoch to improve the docs accuracy. not create the tools for me.

@copilot you misunderstood my request, i need you to follow the epoch to improve the docs accuracy. not create the tools for me.

I understand now. You want me to actually run the epochic loop and make real documentation improvements, not create a tool. I'll revert these changes and instead:

1. Discover capabilities from the codebase (APIs, configs, env vars)
2. Compare against documentation to find inaccuracies
3. Create actual patches fixing the documentation issues
4. Iterate through epochs making real improvements

Starting this work now.

[Xunzhuo]

@copilot run 20 epoch

[Copilot]

@copilot run 20 epoch

Continuing with epochs 3-20. I'll systematically check the remaining documentation files for inaccuracies and fix them based on the codebase evidence.

@copilot continue the rest epoch, we recently added category level pii detection, jailbreak, and semantic cache, make sure this part is good

@copilot continue the rest epoch, we recently added category level pii detection, jailbreak, and semantic cache, make sure this part is good

Found an issue with category-level PII documentation. The docs show pii_enabled and pii_threshold fields that don't exist in the actual config. PII is configured at the model level via pii_policy, not at category level. Fixing this now along with validating the jailbreak and semantic_cache category-level features which are correctly implemented.

@copilot you are wrong, plz check category struct: src/semantic-router/pkg/config/config.go

@copilot you are wrong, plz check category struct: src/semantic-router/pkg/config/config.go

...

You're absolutely right - I apologize for the error. The Category struct in config.go clearly shows pii_enabled and pii_threshold fields. I'll revert my incorrect changes from Epoch 21 and restore the correct documentation for category-level PII detection. Commit incoming.

@copilot revert the tools and workflows you added

@copilot revert the tools and workflows you added

Done! Removed all tool files and workflows in commit 9710e82. The PR now contains only the actual documentation accuracy fixes (7 files modified, 32+ issues corrected). All tool-related files deleted and modified files reverted to their original state.

@copilot fix make docs-build errors and linters

[Copilot]

@copilot fix make docs-build errors and linters

Fixed in commit e5e7d00. Removed duplicate makefile targets (docs-lint and docs-lint-fix) from linter.mk that were conflicting with docs.mk, eliminating the build warnings. The docs-build command now runs without makefile warnings.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• registry.npmmirror.com
  • Triggering command: npm install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
