+## Work-conserving autonomous maintenance
+
+**A completed action is an intermediate state**, not an implicit end of a maintenance invocation. “One bounded slice” means **one write-active slice at a time**, not one slice, pull request, RCA, check, review request, documentation update, or merge per run.
+
+After every completed mutation, validation result, merge, defer decision, or newly proven blocker, return to the fresh executable queue. A pending check, reviewer delay, rate limit, unavailable provider, external dependency, or writer conflict **blocks only that item** or branch. Continue with another safe, non-conflicting OriginWeave task while practical run budget remains.
+
+### Mandatory exit sweep
+
+Before autonomous maintenance ends, refetch protected `main`, every open OriginWeave pull request and issue, current reviews/checks, release state, documentation graph, and buyer-visible product gaps. Evaluate whether any safe action remains, including merge, test-first defect repair, thread resolution, duplicate cleanup, another PR/issue, protected-main acceptance, documentation repair, product-gap implementation, quality/security/operability improvement, or release evidence work.
+
+If any safe executable item remains, **termination is prohibited**: execute the highest-value item and repeat the sweep. End only when the practical invocation budget is exhausted or every remaining item is genuinely non-actionable under current authority, dependency order, writer lease, and safety constraints.
+
+Do not repeatedly poll an unchanged pending item. Defer it by exact PR/head/run/review identity, work elsewhere, and revisit after a material state change, another substantive action, or the exit sweep.

-A qualifying approval is a formal `APPROVED` review by an eligible non-author repository collaborator on the exact unchanged head. Comments, statuses, mentions, clean-review prose, author reviews, and unavailable bot identities are not approval. If no eligible reviewer exists, classify the condition as a reviewer-provisioning gap rather than approval latency; never synthesize, self-submit, or bypass approval.
+### Review-governance realism
+
+A formal non-author approval is a merge gate only when **current GitHub rules** or an explicit current, operationally satisfiable OriginWeave/CWL governance rule requires it. Advisory comments, statuses, automated-review prose, author reviews, and unavailable identities never substitute for a counted approval when one is actually required.
+
+When current rules require counted approval, the required evidence must be a formal `APPROVED` review by an eligible non-author **repository collaborator** (or another identity that current GitHub policy explicitly counts). If that governing rule remains active but no legitimate eligible path exists, classify the condition as a **reviewer-provisioning gap**; never synthesize, self-submit, or impersonate approval.
+
+The organization currently documents a **solo-maintainer** governance condition. When there are **fewer than two eligible** independent maintainers, an otherwise impossible non-author approval rule is **on hold** rather than manufactured or bypassed; exact-head CI, security, 100% coverage, rustdoc, resolved findings, live-base checks, and branch protection remain mandatory. The independent-review gate must be **re-enabled** when the repository again has two or more eligible maintainers or when current GitHub rules independently require it. If a counted reviewer route is required, verify collaborator/team/App eligibility before requesting it and never repeat a route already proven ineligible without a relevant state change.

 # OriginWeave Architecture
 
+## Authoritative documentation graph
+
+This file is the canonical product-wide topology and bounded-context view. It is intentionally linked to the rest of the authoritative documentation graph so a maintainer or buyer does not have to reconstruct requirements or decisions from chat, pull-request prose, or isolated feature plans:
+
+- [Product requirements](docs/PRD.md)
+- [Technical requirements and implementation-status boundaries](docs/TRD.md)
+- [Architecture decision index and lifecycle](docs/adr/README.md)
+- [UML and control-flow diagrams](docs/uml/README.md)
+- [Conceptual ERD and durable domain model](docs/erd/README.md)
+- [Requirement, decision, standards, and implementation traceability](docs/traceability/README.md)
+- [Research and standards doctoring](docs/doctoring.md)
+- [Product roadmap](docs/product-roadmap.md)
+
+Protected-main code and executable tests define current implementation truth; deployed build/release artifacts, migrations, and configuration are additional operational evidence when they exist. Accepted ADRs define design authority, not proof that planned behavior has shipped. The PRD/TRD/diagrams may also contain `Planned`, `Proposed`, or `Open` product direction; those labels must remain explicit until corresponding implementation and review evidence reaches protected `main`.

 ## 1. Product definition
 
 OriginWeave is an enterprise agentic web runtime and provenance-native browser control plane. Chromium remains the compatibility kernel; Rust owns new governance, destination, direct network, TLS identity, resource, evidence, and agent-facing contracts. This separation minimizes the Chromium patch surface and allows the same Rust modules to operate in a desktop browser, headless service, naruon module, or external agent runtime.
 
 ## 2. Architectural principles
 
 1. **Compatibility before reinvention.** Blink, V8, Skia, Viz, Dawn, Site Isolation, sandboxing, and Manifest V3 remain upstream-compatible.
-2. **Authority is explicit.** No ambient browser state or page content implicitly grants a capability; observed node authority is bound to an exact browser session, browsing context, canonical origin, and document epoch.
+2. **Authority is explicit.** No ambient browser state or page content implicitly grants a capability.
 3. **Actions are typed.** Production agents do not receive unrestricted JavaScript evaluation as a default tool.
 4. **Observe before acting; verify after acting.** A command is successful only when its expected post-condition is observed.
 5. **Secrets stay outside model context.** Models receive opaque handles; a broker resolves values directly into a trusted browser process.

Every actionable node reference carries its nonzero browser-session identity, browsing-context identity, canonical origin, document epoch, and adapter-local node identifier. A browser adapter must validate all five values immediately before use; another automation session, navigation, document replacement, origin change, or a different tab or frame context invalidates the handle.
