+# ADAPT Phase 3.1 — Production Blocking Stabilization
+
+Phase 3.1 places a maintained wide-spectrum native DNR substrate underneath the
+verified Phase 3 causal/adaptive control loop.
+
+## Runtime safety
+
+- Every `getComputedStyle` and geometry read in the page sensor goes through a
+ fail-closed DOM boundary.
+- Sensor extractors are independently contained so a hostile/transient DOM state
+ cannot crash `content.js`.
+- `chrome.runtime.sendMessage()` promise rejections are consumed during service
+ worker restart/extension reload.
+- Opaque element refs prune disconnected DOM nodes to avoid long-lived SPA
+ retention.
+- Mutation observation re-attaches after early document-start and now records
+ bounded anti-block-like remove/reinsert cycles.
+
+## Production network layer
+
+`npm run build:full`:
+
+1. builds the verified extension;
+2. atomically refreshes maintained filter text with a validated-cache fallback;
+3. generates packaged redirect/scriptlet resources;
+4. compiles curated filter families into Chromium DNR with the official AdGuard
+ converter;
+5. preserves `ruleset_baseline`;
+6. enables only the Base list in the manifest so the artifact fits Chromium's
+ guaranteed static-rule baseline;
+7. emits a catalog that lets the service worker greedily enable optional
+ Tracking / URL tracking / anti-adblock / popup / annoyance / malicious sets
+ only when live static-rule capacity allows;
+8. generates conservative generic cosmetic CSS from the Base list, dropping any
+ generic selector that has a site-specific exception anywhere in the source
+ list.
+
+## Debugging
+
+`npm run build:debug` emits an unminified content bundle with source maps.
+
+## Verification
+
+Run:
+
+```bash
+npm run typecheck
+npm run build:full
+npm run test:unit
+npm run test:runtime
+npm run test:e2e
+```
+
+The runtime regression specifically exercises body replacement, text/comment
+node churn, and anti-block-like overlay reinsertion while watching Chromium's
+runtime exception stream.

+# Phase 3.1B AI Boundaries
+
+## Deterministic path
+
+Known network, cosmetic, procedural, and supported scriptlet rules are compiled
+before page load. A normal visit therefore requires zero AI calls and zero
+exploratory experiments.
+
+## Novel path
+
+The existing Phase 3 path remains:
+
+1. normalize scoped events;
+2. build an opaque evidence packet;
+3. generate bounded hypotheses;
+4. optionally rank with an advisory planner;
+5. validate through `PolicyValidator`;
+6. run the smallest reversible experiment;
+7. measure health and update belief;
+8. promote only a successful, scoped intervention to a recipe.
+
+AI is not allowed to emit executable JavaScript, raw selectors, arbitrary DNR,
+or browser commands. The new page plane accepts only compiled filter data and
+typed scriptlet descriptors from the build pipeline.
+
+## Provider failure
+
+Provider failure, malformed output, prompt injection, or stale evidence must
+fall back to deterministic blocking or abstention. Baseline blocking never
+depends on an AI provider being reachable.

+# Phase 3.1B Architecture
+
+## Plane A: native network fast path
+
+The existing Phase 3.1 v6 pipeline remains responsible for DNR conversion,
+sharding, static quota accounting, optional capacity-aware enablement, and
+redirect-resource validation. The baseline ruleset and causal DNR transaction
+engine are preserved.
+
+## Plane B: compiled page filtering
+
+`src/page/filtering/compiler.ts` parses a bounded subset of maintained cosmetic
+and scriptlet syntax into a typed bundle. The build writes:
+
+- `dist/phase31-page-cosmetic.css` for generic plain CSS at document start;
+- `dist/page-filtering/index.json` for domain-specific, exception, procedural,
+ and audited scriptlet descriptors;
+- `dist/phase31/BUILD-MANIFEST.json` for source hashes, counts, versions, and
+ artifact provenance.
+
+`PageFilteringRuntime` is event-driven, frame-local, service-worker independent,
+and re-applies on SPA history changes and bounded mutation batches. It limits
+candidate traversal, degrades under mutation storms, and catches hostile DOM
+errors.
+
+Supported procedural primitives are `:has-text`, `:matches-css`, `:remove`, and
+`:remove-attr`. Unsafe or unimplemented primitives are recorded instead of
+silently treated as ordinary selectors.
+
+## Plane C: causal anti-adblock response
+
+The verified Phase 3 causal graph, epoch scoping, health measurement,
+transaction rollback, belief updates, and recipe promotion remain intact. The
+new page plane only adds deterministic observations/interventions; it does not
+replace the causal engine or grant AI direct page authority.
+
+## Plane D: bounded AI
+
+Known filter matches do not call AI. Novel behavior continues through the
+existing opaque evidence, deterministic candidate, policy validation,
+reversible experiment, health measurement, and recipe promotion path.
+
+## Main-world boundary
+
+The only new MAIN-world primitive is `set-constant` for a single validated
+top-level property name and a small typed value set. Prototype paths, arbitrary
+source, eval, Function constructors, remote code, and AI-provided scriptlets
+are rejected.

+# Phase 3.1B Final Verification
+
+## Authoritative command
+
+```bash
+npm run verify:phase31b
+```
+
+The command runs typecheck, the full filter build, page compiler tests,
+provenance/integrity checks, unit and Phase 3 regressions, the synthetic
+adversarial lab, runtime stability, Chromium E2E, and bundle security checks.
+It writes the machine-readable result to `artifacts/phase31b/latest.json` and
+returns nonzero on the first failed gate.
+
+## Current evidence
+
+- Baseline before implementation: 140 unit tests passed.
+- New page compiler/lab unit coverage: 5 tests passed.
+- Build artifact generation produced a page bundle, generic CSS, and a build
+ manifest from six maintained filter sources.
+- Authoritative verification passed on 2026-08-13 UTC.
+- The full gate reported 145 unit tests, 34 Chromium E2E tests across 8 files,
+ 1 synthetic adversarial lab test, 1 runtime-stability test, 5 page/compiler
+ tests, integrity, typecheck, build, and bundle security checks all green.
+- The causal acceptance evidence includes a rolled-back scroll experiment,
+ a committed bait-preservation experiment, and restart invalidation with zero
+ exploration after restart.
+
+## Completion rule
+
+Passing tests do not clear the documented licensing blocker or prove universal
+YouTube/anti-adblock behavior. Both remain explicit release decisions.

+
+STATUS
+------
+IMPLEMENTED — VERIFICATION GREEN; RELEASE BLOCKED
+
+BRANCH
+------
+feat/phase31b-page-plane
+
+COMMITS
+-------
+Pending local commit.
+
+PULL REQUEST
+------------
+Pending push and PR creation.
+
+ARCHITECTURE IMPLEMENTED
+------------------------
+Network plane: existing v6 maintained DNR compiler and capacity-aware shards.
+Page plane: independently implemented typed cosmetic/procedural compiler,
+document-start CSS, domain/exception matching, bounded mutation reapplication,
+and audited isolated/Main scriptlet boundary.
+Anti-adblock plane: existing Phase 3 causal graph, rollback, health, and recipe
+promotion preserved.
+AI plane: existing advisory deterministic → AI → abstain cascade preserved;
+known page rules do not call AI.
+
+MAJOR FILES CHANGED
+-------------------
+`src/page/filtering/compiler.ts` → parses maintained page-filter syntax.
+`src/page/filtering/runtime.ts` → bounded frame-local page runtime.
+`src/page/filtering/scriptlets.ts` → audited isolated/procedural primitives.
+`scripts/build-page-filtering.ts` → reproducible page artifacts and manifest.
+`scripts/verify-phase31b.ts` → authoritative verification gate.
+`tests/fixtures/phase31b/adversarial-corpus.json` → deterministic lab matrix.
+
+FILTER COVERAGE
+---------------
+Network rules: existing Phase 3.1 v6 corpus.
+Cosmetic rules: 68,185 compiled records in the current cache.
+Exceptions: 1,623 compiled records.
+Scriptlet rules: 7,631 parsed; 1,860 supported by the audited allowlist.
+Procedural/extended rules: bounded `:has-text`, `:matches-css`, `:remove`, and
+`:remove-attr`; unsupported forms are recorded.
+Redirect resources: existing v6 path, subject to the license review.
+
+TEST RESULTS
+------------
+Typecheck: PASS.
+Unit: 145 tests PASS, including 140 baseline and 5 page/lab tests.
+Phase 3 regression: PASS; acceptance sequence commits the true mechanism.
+Page filtering: 5 focused tests PASS; integrity gate PASS.
+Anti-adblock: 1 synthetic Chromium test PASS.
+Runtime: 1 body-replacement/mutation-stability test PASS.
+Chromium E2E: 34 tests PASS across 8 files.
+Bundle security: 4 tests PASS.
+Authoritative command: PASS on 2026-08-13 UTC.
+Machine evidence: `artifacts/phase31b/latest.json`.
+
+REAL-WORLD RESULTS
+------------------
+Site/category: synthetic local lab only.
+Blocking: generic fixture coverage is automated; broad live-site coverage is pending.
+Detector behavior: causal synthetic coverage is retained; no universal claim.
+Breakage: local fixture keeps main content and SPA churn alive.
+Notes: comparative uBO Lite/AdGuard/no-blocker benchmarks are not complete.
+
+YOUTUBE
+-------
+Pre-roll: not observed in this run.
+Mid-roll: not observed in this run.
+Display/sponsored: compiler preserves maintained rules; live result pending.
+Playback: not manually validated in this run.
+SPA: runtime re-applies on history events; live validation pending.
+Errors: hostile DOM protections retained; final Chromium gate passed.
+
+PERFORMANCE
+-----------
+Measured overhead: mutation work is coalesced and bounded; comparative
+benchmark pending.
+Service-worker behavior: baseline page filtering is content-script/data driven.
+Idle behavior: no permanent polling; mutation work is coalesced and bounded.
+Comparison summary: not yet available.
+
+SECURITY
+--------
+Remote code: none in the new page plane.
+Secrets: bundle integrity gate rejects known secret/development markers.
+MAIN-world scriptlets: only top-level `set-constant` is allowlisted.
+WAR exposure: bounded and dynamic when present.
+License status: unresolved GPL build-toolchain review blocks proprietary release.
+
+AI
+--
+Known-site AI calls: zero by design.
+Novel-path behavior: existing causal evidence and bounded experiment path.
+Validator: existing `PolicyValidator` remains authoritative.
+Recipe promotion: existing successful-intervention promotion preserved.
+
+KNOWN LIMITATIONS
+-----------------
+The page bundle is currently large, unsupported maintained syntax is explicit,
+closed shadow roots are not claimed, live YouTube and broad real-world
+comparison are pending, and the GPL build-toolchain decision is unresolved.
+
+VERIFICATION COMMAND
+--------------------
+npm run verify:phase31b
+
+MERGE RECOMMENDATION
+--------------------
+NO for proprietary release until licensing consent/replacement and live
+validation are resolved. Engineering verification itself is green.
+
+USER ACTION REQUIRED
+--------------------
+Choose compatible licensing for the current AdGuard build path or approve its
+replacement before distributing ADAPT as proprietary software. Provide one
+clean-profile YouTube ad/playback observation for the final acceptance matrix.

+# Phase 3.1B License Review
+
+Status: distribution review required before a proprietary release.
+
+ADAPT has no `LICENSE` file in the repository. That means the project’s own
+distribution rights are not explicitly documented and must be resolved by the
+owner before publication.
+
+| Dependency or data | Observed license | Use in this branch | Distribution consequence |
+|---|---|---|---|
+| `@adguard/tswebextension` 5.0.0 | GPL-3.0-only in installed package metadata | Existing build-time CLI dependency; not imported by the new page runtime | Do not ship its runtime or generated GPL scriptlet code in a proprietary extension without permission or GPL-compatible distribution. |
+| `@adguard/tsurlfilter` 5.0.1 | GPL-3.0-only in installed package metadata | Transitive/build/reference dependency | Do not copy its parser, matcher, or content runtime into ADAPT. |
+| `@adguard/dnr-rulesets` 4.2.x | GPL-3.0-only in installed package metadata | Existing maintained DNR build path | Treat the current build toolchain as a licensing review item; the generated JSON must not be assumed to clear the upstream code license. |
+| AdGuard filter text IDs 2, 3, 17, 19, 21, 208 | Source-specific headers and registry terms | Data input; source version and SHA-256 are recorded | Retain source headers, provenance, and any attribution required by each list. Do not collapse all list terms into one license. |
+| EasyList/EasyPrivacy | Not bundled by this branch | Research/benchmark reference only | No distribution consequence until explicitly added and reviewed. |
+| uBlock Origin Lite source | GPL-3.0 | Architecture/reference only | No source copied or linked into ADAPT. |
+| New ADAPT page compiler/runtime | ADAPT-authored; project license unresolved | New implementation | Owner must choose and document the project license. |
+
+## Copyleft boundary
+
+The page compiler, page runtime, isolated scriptlets, MAIN-world bridge, tests,
+and documentation in this branch are independently implemented. No uBO/uBOL or
+AdGuard runtime source was copied. The current DNR build still invokes the
+existing AdGuard converter/tooling path, so this branch is not yet a legal
+clearance for a proprietary distributed artifact.
+
+## Required owner decision
+
+Before release, choose one of:
+
+1. Obtain compatible commercial/dual-license permission for the required
+ AdGuard build/runtime pieces and record it here.
+2. Replace the GPL build-time converter and redirect-resource generation with an
+ independently licensed implementation and separately review every filter
+ data source.
+3. Distribute ADAPT under GPL-compatible terms with complete corresponding
+ source and attribution.
+
+Until that decision is recorded, the merge recommendation is **NO** for a
+proprietary release. This is a licensing blocker, not a TypeScript or test
+failure.

+# Phase 3.1B Performance
+
+## Build snapshot
+
+The maintained cache generated 68,185 cosmetic records, 1,860 supported
+scriptlet records, 1,623 exceptions, and 8,046 unsupported records on the
+2026-08-13 build. The generated page data is intentionally explicit and is
+tracked in `dist/phase31/BUILD-MANIFEST.json`.
+
+## Runtime controls
+
+- Generic plain CSS is installed declaratively at document start.
+- Runtime work is scheduled once per coalesced mutation window.
+- Candidate queries are capped at 500 elements per rule and 800 procedural
+ rules per pass.
+- Mutation storms enter a temporary delayed mode rather than polling faster.
+- No permanent 50ms interval exists.
+- Page filtering does not require a resident service worker.
+
+## Measurement status
+
+The authoritative gate runs the synthetic lab, runtime stability suite, and
+Chromium E2E tests. A fair uBO Lite/AdGuard MV3/no-blocker benchmark on clean
+profiles is not yet complete; no comparative marketing claim should be made.
+The current 14 MB uncompressed page bundle is a known optimization target and
+should be compacted/indexed before a production-quality release.

+## YouTube acceptance
+
+The compiler preserves the maintained YouTube exception and `set-constant`
+descriptor when present in the selected filter source. This is not proof that
+pre-roll, mid-roll, sponsored cards, or every SPA route is blocked. No manual
+live ad occurrence was observed during this run, so the real-world YouTube
+rows remain pending and must not be presented as passing.
+
+The single manual observation needed for the next validation pass is: on a
+clean Chromium profile with ADAPT enabled, report whether a genuine YouTube
+pre-roll or mid-roll appears and whether playback, seeking, volume, captions,
+comments, playlists, live streams, and Shorts navigation remain healthy.

+# Phase 3.1B Research Ledger
+
+Access date for the sources below: 2026-08-13. The repository and generated
+artifacts remain the source of truth for implementation claims.
+
+## Chromium MV3
+
+| Primary source | Finding | Decision |
+|---|---|---|
+| https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest | Chrome permits up to 100 declared static rulesets, 50 enabled at once, and guarantees at least 30,000 enabled static rules across an extension. Dynamic rules persist; session rules do not. | Preserve the existing baseline plus capacity-aware optional shards. Do not assume the guaranteed floor equals the live global capacity. |
+| https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest | The documented minimum dynamic quota is 5,000, safe dynamic rules can use the larger 30,000 quota introduced in Chrome 121, and regular-expression rules are separately limited to 1,000 per rule class. | Keep causal experiments in the existing bounded DNR controller and reserve page filtering for declarative/package-time data. |
+| https://developer.chrome.com/docs/extensions/reference/api/scripting | `registerContentScripts()` and `executeScript()` support explicit content-script registration and execution worlds. | Use the content script as the reliable bootstrap and reserve MAIN-world execution for the single audited `set-constant` primitive. |
+| https://developer.chrome.com/docs/extensions/develop/concepts/content-scripts | `document_start`, `all_frames`, and match-pattern behavior define early, frame-scoped injection. | Keep page filtering at document start and all frames, with frame-local state. |
+| https://developer.chrome.com/docs/extensions/develop/concepts/service-workers/lifecycle | Extension service workers normally terminate after 30 seconds of inactivity; long-running requests have a five-minute ceiling. | Baseline page filtering must not depend on a resident worker. The page bundle loads from the content script. |
+| https://developer.chrome.com/docs/extensions/reference/manifest/web-accessible-resources | `use_dynamic_url` changes how exposed resources are addressed and is optional. | Keep the existing WAR surface minimal and dynamic where redirects are present. |
+
+## AdGuard
+
+| Primary source | Finding | Decision |
+|---|---|---|
+| https://github.com/AdguardTeam/tsurlfilter | The monorepo separates parsing, matching, extension integration, DNR conversion, and prebuilt rulesets. | Reuse the conceptual separation, not the GPL runtime implementation. |
+| https://github.com/AdguardTeam/tsurlfilter/tree/master/packages/tswebextension | `tswebextension` integrates static filter IDs, custom filters, ruleset paths, content filtering, Extended CSS, and scriptlets for MV3. | ADAPT implements a smaller audited data contract with explicit unsupported-rule accounting instead of importing the runtime. |
+| https://raw.githubusercontent.com/AdguardTeam/tsurlfilter/master/LICENSE | The upstream repository is GPLv3. | Do not copy or bundle its runtime into a proprietary ADAPT extension without a separate licensing decision. |
+| https://filters.adtidy.org/extension/chromium-mv3/filters/2.txt | The maintained filter endpoint provides the source text and metadata used by the build. | Preserve source IDs, versions, SHA-256 hashes, and provenance in `BUILD-MANIFEST.json`. |
+
+## uBlock Origin Lite
+
+| Primary source | Finding | Decision |
+|---|---|---|
+| https://github.com/uBlockOrigin/uBOL-home/blob/main/README.md | uBO Lite describes an entirely declarative MV3 design where the browser handles CSS/JS injection and the service worker is not a permanent filtering process. | Make known filtering independent of service-worker liveness and keep AI/causal work off the ordinary page-load path. |
+| https://api.github.com/repos/uBlockOrigin/uBOL-home | The repository reports GPL-3.0. | Reference architecture and benchmark target only; no source copied. |
+
+## Resulting boundary
+
+The chosen boundary is: DNR for network decisions, compiled filter data plus
+CSS for known page rules, a bounded content runtime for domain/procedural rules,
+one narrowly allowlisted MAIN-world primitive, the existing Phase 3 causal
+engine for unresolved reactions, and the existing advisory AI cascade only
+after evidence and policy validation.

+# Phase 3.1B Security Review
+
+## Reviewed controls
+
+- No AI-generated JavaScript or selectors enter the page runtime.
+- No `eval` or `new Function` is permitted in production bundles by the
+ integrity gate.
+- Scriptlet names, worlds, arguments, and domain scopes are typed build data.
+- Unsupported scriptlets are recorded and never executed.
+- MAIN-world execution is limited to `set-constant` with a top-level property
+ and a small value allowlist.
+- Generic and domain CSS is selector-validated and bounded.
+- The page observer catches DOM, geometry, and computed-style faults.
+- Manifest WAR exposure is bounded and dynamic when redirect resources exist.
+- Build provenance includes source version metadata and SHA-256 hashes.
+- The existing production bundle test continues to reject Azure endpoints,
+ development markers, and secret names.
+
+## Supply-chain findings
+
+The current AdGuard build dependencies are GPL-3.0-only according to installed
+package metadata. This is documented in `LICENSE_REVIEW.md` and remains a
+release blocker until the build path is relicensed, replaced, or explicitly
+accepted under compatible distribution terms.
+
+## Remaining risks
+
+Filter text is external input and must continue to be fetched with identity,
+format, cache, and hash validation. A future compact page index must preserve
+the same exception semantics. Security review is not complete for any new
+MAIN-world scriptlet beyond the current `set-constant` implementation.

+# Phase 3.1B Threat Model
+
+## Threat actors
+
+- DOM bait detectors measuring `offsetHeight`, bounding boxes, or computed CSS.
+- Network-probe and blocked-request detectors.
+- Mutation and reinsertion detectors.
+- Timer, reload-loop, scroll-lock, pointer-lock, and fullscreen gates.
+- JavaScript environment and extension-resource probes.
+- SPA scripts that re-render or replace the body.
+- Benign dialogs that resemble anti-adblock prompts.
+
+## Extension fingerprint surface
+
+The implementation avoids stable ADAPT marker nodes, page-visible production
+logging, ADAPT globals, arbitrary injected source, and permanent polling loops.
+Generic CSS is declarative. Runtime observation is bounded and event-driven.
+The existing redirect resources use dynamic WAR URLs when present.
+
+## Safety model
+
+- Isolated-world scriptlets are the default.
+- MAIN-world execution is explicit, typed, narrowly allowlisted, and routed
+ through `chrome.scripting.executeScript`.
+- Page-controlled DOM input crosses sensor fault boundaries.
+- Causal actions are reversible and health-checked.
+- Consent, login, paywall, and benign-text cases remain negative controls.
+
+## Honest limitation
+
+This does not claim invisibility or universal anti-adblock resistance. The
+adversarial corpus is a measurable test set, not proof against untested
+detectors. Closed shadow roots, arbitrary proprietary scriptlet syntax, and
+page-specific MAIN-world behavior remain explicit limitations.

+# Phase 3.1B Final Report
+
+Date: 2026-08-13 UTC
+Branch: `feat/phase31b-page-plane`
+PR: #2 remains open and was not merged. No commit or push was created by this run.
+
+## Verification
+
+- Authoritative command: `ADAPT_PHASE31_OFFLINE=1 npm run verify:phase31b`
+- Verdict: `PASSED`
+- Gate count: 10
+- Typecheck: PASS
+- Unit: 151/151 tests across 32 files
+- Focused page/index tests: 8/8
+- Runtime stability: 1/1
+- Chromium E2E: 65/65 tests across 8 files
+- Bundle security: 4/4
+- Package integrity: PASS
+- Adversarial corpus: 30/30 executable scenarios
+
+## Coverage
+
+- Cosmetic rules: 68,185
+- Exceptions: 1,623
+- Scriptlet descriptors: 7,631
+- Parsed descriptors including scriptlet exceptions: 7,637
+- Fully executable: 4,473
+- Unsupported by name: 2,884
+- Unsupported by arguments: 49
+- Unsafe: 225
+- Exception-suppressed: 6
+
+The counts reconcile without optimistic support claims. A descriptor is counted
+as fully executable only when its name, complete argument grammar, property path,
+execution world, domain scope, and exception behavior pass compiler validation.
+
+## Indexed Page Plane
+
+- Previous monolithic index: 15,022,819 bytes
+- New startup index: 412 bytes
+- Total page-filtering artifacts: 30,235,251 bytes
+- YouTube sample per-frame load: 1,760,804 bytes
+- YouTube sample parse: 10.18 ms in the final benchmark run
+- Selected indexed rules: 735
+- Domain shards: 339
+- Early shards: 337
+- Mutation lookup: 0.161 ms for 2,000 checks
+- Full 14 MB bundle parse per frame: no
+
+Static early registrations use hostname-filtered `include_globs`; this avoids
+the Chromium startup failure caused by parsing tens of thousands of host match
+patterns while retaining document-start MAIN-world ordering.
+
+## Early Plane
+
+- Race fixture: PASS
+- Ordering: the early MAIN-world set-constant is observed before the page's
+ extremely early inline detector
+- Exact wall-clock script execution timestamp: not instrumented; the acceptance
+ assertion is deterministic ordering, not a guessed microsecond measurement
+
+## Unsupported Demand
+
+Generated report: `artifacts/phase31b/unsupported-scriptlet-frequency.json`.
+The current maintained corpus has 3,158 unsupported descriptors. Highest demand:
+
+| Primitive | Unsupported | Total | Reason |
+|---|---:|---:|---|
+| `prevent-addEventListener` | 421 | 421 | unsupported by name |
+| `adjust-setInterval` | 348 | 348 | unsupported by name |
+| `set-cookie` | 337 | 337 | unsupported by name |
+| `set-local-storage-item` | 292 | 292 | unsupported by name |
+| `prevent-element-src-loading` | 213 | 213 | unsupported by name |
+| `adjust-setTimeout` | 165 | 165 | unsupported by name |
+| `trusted-set-local-storage-item` | 143 | 143 | unsupported by name |
+| `trusted-click-element` | 136 | 136 | unsupported by name |
+| `abort-on-stack-trace` | 130 | 130 | unsupported by name |
+| `trusted-replace-node-text` | 91 | 91 | unsupported by name |
+
+Requested high-impact primitives are audited and counted accurately. Current
+coverage includes `abort-on-property-read` 324/368, `abort-on-property-write`
+142/156, `abort-current-inline-script` 688/697, `prevent-setTimeout` 469/477,
+`prevent-eval-if` 39/40, `json-prune` 121/143, and `prevent-window-open` 478/479.
+`prevent-fetch` and `prevent-xhr` have no parsed descriptors in the current
+maintained corpus, although the audited runtime implementations are present.
+
+## Mutation And Lifecycle
+
+- DOM transformation scriptlets are classified as reapply-on-mutation or
+ element-scoped where required.
+- SPA navigation and body replacement reapply deterministically.
+- Mutation storm handling is coalesced and bounded; no unbounded polling was
+ introduced.
+- Lifecycle, frame, CSP, shadow DOM, worker restart, and negative-control rows
+ are included in the 30/30 corpus artifact.
+
+## YouTube And Real-World Validation
+
+- YouTube: `NOT OBSERVED`
+- Pre-roll: not observed
+- Mid-roll: not observed
+- Playback, seeking, volume, captions, comments, playlists, Shorts, sponsored
+ cards, and live SPA behavior: not manually validated
+- uBO Lite comparison: pending
+- AdGuard MV3 comparison: pending
+- No-blocker comparison: pending
+
+No live-site success claim is made. A genuine ad occurrence must be observed on
+a clean profile before YouTube can be marked PASS.
+
+## Licensing And Merge Recommendation
+
+The existing AdGuard build/toolchain and related data path remain an explicit
+GPL/licensing review blocker for proprietary distribution. No GPL runtime code
+was imported to implement the new primitives. The page-plane engineering gate
+is green, but the merge recommendation remains **NO for proprietary release**
+until licensing is resolved and clean-profile real-world validation is complete.

# Phase 3.1B Real-World Validation
+This procedure is intentionally a release gate, not a marketing checklist.
+Run each comparison on a fresh Chromium profile with cache, cookies, account
+state, and extensions reset between runs. Record the browser version, OS,
+profile identifier, timestamp, URL, and console/network errors for every row.
+
+## Procedure
+
+1. Build ADAPT from the candidate commit and install only that unpacked build.
+2. Repeat the same navigation sequence with uBO Lite, AdGuard MV3, and no blocker.
+3. For each category, capture one clean load, one reload, one back/forward cycle,
+ and one SPA route transition where the site supports it.
+4. Record blocked requests, visible ad occurrences, content survival, playback
+ controls, console errors, and CPU/memory symptoms without changing page state.
+5. Mark a row **PASS** only when the observation is reproducible twice; use
+ **NOT OBSERVED** when no genuine ad occurrence was seen, never convert that
+ state into a success claim.
+
+Use the following per-category checks:
+
+- YouTube: pre-roll, mid-roll, sponsored cards, playback, seeking, volume,
+ captions, comments, playlists, Shorts, SPA navigation, and JavaScript errors.
+- News publisher: display, sticky, in-article, consent, paywall, login, and
+ article navigation breakage.
+- Social/forum: feed loading, infinite scroll, media playback, compose/reply,
+ login state, and false positives on ordinary “advertisement” text.
+- Search: result integrity, sponsored result handling, pagination, and query
+ navigation.
+- Ecommerce: product grid, cart, checkout, reviews, recommendations, and
+ third-party payment frames.
+- Streaming SPA: startup, ad break behavior, seeking, captions, route changes,
+ and player controls.
+- Anti-adblock demo/ad-heavy page: detector trigger, overlay, scroll lock,
+ pointer behavior, reinsertion, and page content survival.
+
+The synthetic 30/30 corpus and local Chromium suites are necessary but do not
+replace this live comparison. A real YouTube result requires a genuine ad
+occurrence observed during the run.
+
## Matrix
| Category | ADAPT | uBO Lite | AdGuard MV3 | No blocker | Status |
|---|---|---|---|---|---|
-| Large video site / YouTube | Pending live occurrence | Pending | Pending | Pending | Requires clean-profile manual/live observation. |
+| Large video site / YouTube | NOT OBSERVED | Pending | Pending | Pending | No live ad occurrence claimed. |
| News publisher | Pending | Pending | Pending | Pending | Not yet measured. |
| Forum/social feed | Pending | Pending | Pending | Pending | Not yet measured. |

# Phase 3.1B Final Report
-Date: 2026-08-13 UTC
-Branch: `feat/phase31b-page-plane`
-PR: #2 remains open and was not merged. No commit or push was created by this run.
+Date: 2026-08-14 UTC
+Branch: `feat/phase31b-page-plane`
+PR: #2 remains open and was not merged.
+
+## Root cause
+
+CanYouBlockIt's passive detector bait was being collapsed by maintained cosmetic
+rules that rendered generic selectors as `display:none!important`. The specific
+failure mode was not a page-visible ADAPT marker or a detector-specific script;
+it was ordinary cosmetic filtering changing the bait element's natural layout,
+so its measured height became zero.
+
+## Mechanism implemented
+
+- Added typed cosmetic classification: `ORDINARY_COSMETIC`,
+ `POSSIBLE_DETECTOR_BAIT`, and `CONFIRMED_DETECTOR_BAIT`.
+- Added conservative detector-shaped selector heuristics for exact and
+ equivalent bait names; no blanket exemption for all ad-looking selectors.
+- Excluded possible/confirmed bait from unconditional static generic CSS and
+ runtime cosmetic/procedural hiding. Network/DNR blocking remains unchanged.
+- Added audited reversible bait actions: `BAIT_PRESERVE_LAYOUT`,
+ `BAIT_RESTORE_VISIBILITY`, `BAIT_DISABLE_COSMETIC_HIDE`,
+ `BAIT_PRESERVE_CHILD_STRUCTURE`, with the existing legacy bait action kept as
+ a target-scoped compatibility alias.
+- Bait actions require content-runtime-owned opaque element refs; selectors are
+ rejected by guards, causal remapping, and the DOM executor. The fallback
+ candidate generator no longer invents selectors.
+- Bait preservation restores natural author layout only when a measured hidden
+ state is present. No global geometry, computed-style, XHR, Window, or
+ prototype monkey patches were added.
+- Added production artifact checks that reject detector bait selectors in static
+ cosmetic CSS.
## Verification
-- Authoritative command: `ADAPT_PHASE31_OFFLINE=1 npm run verify:phase31b`
-- Verdict: `PASSED`
-- Gate count: 10
-- Typecheck: PASS
-- Unit: 151/151 tests across 32 files
-- Focused page/index tests: 8/8
-- Runtime stability: 1/1
-- Chromium E2E: 65/65 tests across 8 files
-- Bundle security: 4/4
-- Package integrity: PASS
-- Adversarial corpus: 30/30 executable scenarios
-
-## Coverage
-
-- Cosmetic rules: 68,185
-- Exceptions: 1,623
-- Scriptlet descriptors: 7,631
-- Parsed descriptors including scriptlet exceptions: 7,637
-- Fully executable: 4,473
-- Unsupported by name: 2,884
-- Unsupported by arguments: 49
-- Unsafe: 225
-- Exception-suppressed: 6
-
-The counts reconcile without optimistic support claims. A descriptor is counted
-as fully executable only when its name, complete argument grammar, property path,
-execution world, domain scope, and exception behavior pass compiler validation.
-
-## Indexed Page Plane
-
-- Previous monolithic index: 15,022,819 bytes
-- New startup index: 412 bytes
-- Total page-filtering artifacts: 30,235,251 bytes
-- YouTube sample per-frame load: 1,760,804 bytes
-- YouTube sample parse: 10.18 ms in the final benchmark run
-- Selected indexed rules: 735
-- Domain shards: 339
-- Early shards: 337
-- Mutation lookup: 0.161 ms for 2,000 checks
-- Full 14 MB bundle parse per frame: no
-
-Static early registrations use hostname-filtered `include_globs`; this avoids
-the Chromium startup failure caused by parsing tens of thousands of host match
-patterns while retaining document-start MAIN-world ordering.
-
-## Early Plane
-
-- Race fixture: PASS
-- Ordering: the early MAIN-world set-constant is observed before the page's
- extremely early inline detector
-- Exact wall-clock script execution timestamp: not instrumented; the acceptance
- assertion is deterministic ordering, not a guessed microsecond measurement
-
-## Unsupported Demand
-
-Generated report: `artifacts/phase31b/unsupported-scriptlet-frequency.json`.
-The current maintained corpus has 3,158 unsupported descriptors. Highest demand:
-
-| Primitive | Unsupported | Total | Reason |
-|---|---:|---:|---|
-| `prevent-addEventListener` | 421 | 421 | unsupported by name |
-| `adjust-setInterval` | 348 | 348 | unsupported by name |
-| `set-cookie` | 337 | 337 | unsupported by name |
-| `set-local-storage-item` | 292 | 292 | unsupported by name |
-| `prevent-element-src-loading` | 213 | 213 | unsupported by name |
-| `adjust-setTimeout` | 165 | 165 | unsupported by name |
-| `trusted-set-local-storage-item` | 143 | 143 | unsupported by name |
-| `trusted-click-element` | 136 | 136 | unsupported by name |
-| `abort-on-stack-trace` | 130 | 130 | unsupported by name |
-| `trusted-replace-node-text` | 91 | 91 | unsupported by name |
-
-Requested high-impact primitives are audited and counted accurately. Current
-coverage includes `abort-on-property-read` 324/368, `abort-on-property-write`
-142/156, `abort-current-inline-script` 688/697, `prevent-setTimeout` 469/477,
-`prevent-eval-if` 39/40, `json-prune` 121/143, and `prevent-window-open` 478/479.
-`prevent-fetch` and `prevent-xhr` have no parsed descriptors in the current
-maintained corpus, although the audited runtime implementations are present.
-
-## Mutation And Lifecycle
-
-- DOM transformation scriptlets are classified as reapply-on-mutation or
- element-scoped where required.
-- SPA navigation and body replacement reapply deterministically.
-- Mutation storm handling is coalesced and bounded; no unbounded polling was
- introduced.
-- Lifecycle, frame, CSP, shadow DOM, worker restart, and negative-control rows
- are included in the 30/30 corpus artifact.
-
-## YouTube And Real-World Validation
-
-- YouTube: `NOT OBSERVED`
-- Pre-roll: not observed
-- Mid-roll: not observed
-- Playback, seeking, volume, captions, comments, playlists, Shorts, sponsored
- cards, and live SPA behavior: not manually validated
-- uBO Lite comparison: pending
-- AdGuard MV3 comparison: pending
-- No-blocker comparison: pending
-
-No live-site success claim is made. A genuine ad occurrence must be observed on
-a clean profile before YouTube can be marked PASS.
-
-## Licensing And Merge Recommendation
-
-The existing AdGuard build/toolchain and related data path remain an explicit
-GPL/licensing review blocker for proprietary distribution. No GPL runtime code
-was imported to implement the new primitives. The page-plane engineering gate
-is green, but the merge recommendation remains **NO for proprietary release**
-until licensing is resolved and clean-profile real-world validation is complete.

+- `ADAPT_PHASE31_OFFLINE=1 npm run verify:phase31b`: PASS.
+- Typecheck: PASS.
+- Unit suite: 154/154 tests across 32 files.
+- Full Chromium E2E suite: 69/69 tests across 9 files.
+- Existing 30-scenario adversarial corpus: 30/30, with 22
+ `BLOCKING_PASS`, 5 `NEGATIVE_CONTROL_PASS`, 3 `LIFECYCLE_PASS`, and 0
+ `PRESENCE_ONLY`.
+- Passive stealth corpus: 11/11, with 9 blocking checks and 2 negative
+ controls. The fixture covers height, `offsetHeight`, `clientHeight`,
+ `getBoundingClientRect().height`, computed display/visibility, DOM existence,
+ child structure, timed re-checks, reinsertion, blocked network probes, and a
+ hybrid detector.
+- BlockAdBlock/FuckAdBlock-style local family fixture: PASS; detector code
+ executes normally, bait remains believable, the synthetic ad script is
+ blocked, and no ad content is visible.
+- Page breakage regressions: 0 observed in the 69/69 Chromium suite.
+- Ordinary blocking regressions: 0 observed; all prior blocking and negative
+ controls remain green.
+
+## Coverage and performance
+
+- Detector-sensitive maintained cosmetic rules identified: 2,913 possible;
+ 0 confirmed by causal evidence in the maintained corpus.
+- Generic cosmetic selectors emitted to static CSS: 11,718.
+- Relevant YouTube sample per-frame load: 1,784,162 bytes.
+- Relevant page-plane parse: 8.84 ms.
+- Mutation benchmark: 0.147 ms for 2,000 checks.
+- Full bundle parse per frame: no; indexed startup index remains below 4 KiB.
+
+## Real-world status
+
+- CanYouBlockIt live result: `NOT_OBSERVED`.
+- No detector script was blocked, hidden, spoofed, or replaced in the local
+ acceptance fixture.
+- The final live CanYouBlockIt comparison still requires a manual clean-profile
+ run: ADAPT off must report blocker OFF, and ADAPT on must still report blocker
+ OFF while ad requests remain blocked and visible ads remain absent.
+- YouTube: `NOT_OBSERVED`; no genuine live ad occurrence was tested.
+
+## Release status
+
+Do not merge PR #2. Technical local acceptance is green, but licensing review
+and the manual CanYouBlockIt/clean-profile live acceptance remain release gates.

Generic CSS is declarative. Runtime observation is bounded and event-driven.
The existing redirect resources use dynamic WAR URLs when present.
+## Passive side-effect detection
+
+Passive side-effect detection is distinct from extension fingerprinting. A
+detector can infer blocking without observing an extension name or global by
+measuring the consequences of filtering:
+
+- Cosmetic collapse of detector bait into `display:none`.
+- Missing bait DOM nodes or changed child structure.
+- Zero `offsetHeight`, `clientHeight`, or bounding-rectangle dimensions.
+- `getComputedStyle()` differences in display or visibility.
+- Blocked resource probes, timed re-checks, and bait reinsertion.
+
+The page plane classifies conservative detector-shaped cosmetic selectors as
+possible bait and excludes them from unconditional static hiding. Network
+blocking remains active. Causal bait actions are audited, opaque-ref-only,
+document/frame scoped by the owning content runtime, reversible, and rolled
+back when health checks fail. ADAPT does not globally monkey-patch geometry or
+computed-style APIs and does not whitelist advertising requests.
+
## Safety model
- Isolated-world scriptlets are the default.

## Root cause
-CanYouBlockIt's passive detector bait was being collapsed by maintained cosmetic
-rules that rendered generic selectors as `display:none!important`. The specific
-failure mode was not a page-visible ADAPT marker or a detector-specific script;
-it was ordinary cosmetic filtering changing the bait element's natural layout,
-so its measured height became zero.
-
-## Mechanism implemented
-
-- Added typed cosmetic classification: `ORDINARY_COSMETIC`,
- `POSSIBLE_DETECTOR_BAIT`, and `CONFIRMED_DETECTOR_BAIT`.
-- Added conservative detector-shaped selector heuristics for exact and
- equivalent bait names; no blanket exemption for all ad-looking selectors.
-- Excluded possible/confirmed bait from unconditional static generic CSS and
- runtime cosmetic/procedural hiding. Network/DNR blocking remains unchanged.
-- Added audited reversible bait actions: `BAIT_PRESERVE_LAYOUT`,
- `BAIT_RESTORE_VISIBILITY`, `BAIT_DISABLE_COSMETIC_HIDE`,
- `BAIT_PRESERVE_CHILD_STRUCTURE`, with the existing legacy bait action kept as
- a target-scoped compatibility alias.
-- Bait actions require content-runtime-owned opaque element refs; selectors are
- rejected by guards, causal remapping, and the DOM executor. The fallback
- candidate generator no longer invents selectors.
-- Bait preservation restores natural author layout only when a measured hidden
- state is present. No global geometry, computed-style, XHR, Window, or
- prototype monkey patches were added.
-- Added production artifact checks that reject detector bait selectors in static
- cosmetic CSS.
+CanYouBlockIt's detector bait was excluded from the Phase 3.1B page compiler,
+but `tools/phase31/v6.mjs` independently parsed Base-filter `##` rules and
+generated `phase31-generic-cosmetic.css`. That legacy `:is(...){display:none!important;}`
+stylesheet was the second cosmetic plane, so `.ad-widget` could still collapse
+to zero height and make the detector report an ad blocker.
+
+## Exact fix
+
+- Removed `plainSelector`, `genericHide`, `anyException`, Base `##` parsing,
+ legacy generic CSS chunking, manifest injection, and selector reporting from
+ `tools/phase31/v6.mjs`.
+- `v6.mjs` is now network/DNR and redirect-resource compilation only.
+- Removed the build-time inline generic-CSS fallback from `scripts/build.ts`
+ and the corresponding runtime branch; the page compiler owns the CSS plane.
+- Reused `renderGenericCosmeticCss()` as the single page-plane emitter.
+- Added `cosmeticOwners: 1` and `cosmeticOwner: phase31b-page-plane` to the
+ build manifest and made integrity reject duplicate or undeclared CSS planes.
+- Integrity now enumerates all manifest CSS, all production CSS artifacts, and
+ detector-sensitive selector rules, including `:is(...)` lists.
+- Added deterministic complete-build stealth assertions for the exact `dist`
+ manifest and artifact set.
+- Updated ordinary blocking fixtures to use `.sponsor-div`; `.ad-slot-wrapper`
+ remains a possible detector-bait class and is no longer used as an ordinary
+ cosmetic regression target.
+
+## Build outputs
+
+- Manifest content-script CSS: `phase31-page-cosmetic.css` only.
+- Generated filtering CSS: `dist/phase31-page-cosmetic.css`.
+- Generated UI CSS: `dist/popup/assets/index-WlGjJIoV.css`.
+- Legacy `dist/phase31-generic-cosmetic.css`: absent.
+- Detector-sensitive maintained cosmetic rules: 2,913 possible, 0 confirmed.
+- Generic selectors emitted to the authoritative page CSS: 11,718.
+- Single owner reported by build/integrity: `cosmeticOwners: 1`.
+
+## Provenance
+
+The maintained filter corpus contains `.ad-widget` twice in source filter #2:
+
+- `thewindowsclub.com##.ad-widget`
+- `##.ad-widget`
+
+Both are classified `POSSIBLE_DETECTOR_BAIT` and recorded in
+`dist/phase31/DETECTOR-BAIT-AUDIT.json` with the decision
+`NOT_EMITTED_TO_UNCONDITIONAL_COSMETIC_CSS`.
## Verification
- `ADAPT_PHASE31_OFFLINE=1 npm run verify:phase31b`: PASS.
-- Typecheck: PASS.
+- TypeScript: PASS.
- Unit suite: 154/154 tests across 32 files.
- Full Chromium E2E suite: 69/69 tests across 9 files.
-- Existing 30-scenario adversarial corpus: 30/30, with 22
- `BLOCKING_PASS`, 5 `NEGATIVE_CONTROL_PASS`, 3 `LIFECYCLE_PASS`, and 0
- `PRESENCE_ONLY`.
-- Passive stealth corpus: 11/11, with 9 blocking checks and 2 negative
- controls. The fixture covers height, `offsetHeight`, `clientHeight`,
- `getBoundingClientRect().height`, computed display/visibility, DOM existence,
- child structure, timed re-checks, reinsertion, blocked network probes, and a
- hybrid detector.
-- BlockAdBlock/FuckAdBlock-style local family fixture: PASS; detector code
- executes normally, bait remains believable, the synthetic ad script is
- blocked, and no ad content is visible.
-- Page breakage regressions: 0 observed in the 69/69 Chromium suite.
-- Ordinary blocking regressions: 0 observed; all prior blocking and negative
- controls remain green.
-
-## Coverage and performance
-
-- Detector-sensitive maintained cosmetic rules identified: 2,913 possible;
- 0 confirmed by causal evidence in the maintained corpus.
-- Generic cosmetic selectors emitted to static CSS: 11,718.
-- Relevant YouTube sample per-frame load: 1,784,162 bytes.
-- Relevant page-plane parse: 8.84 ms.
-- Mutation benchmark: 0.147 ms for 2,000 checks.
-- Full bundle parse per frame: no; indexed startup index remains below 4 KiB.
+- Adversarial suite: 34/34 tests; 30/30 corpus rows passed.
+- Corpus classes: 22 `BLOCKING_PASS`, 5 `NEGATIVE_CONTROL_PASS`, 3
+ `LIFECYCLE_PASS`, 0 `PRESENCE_ONLY`.
+- Passive stealth acceptance: 9/9 required checks plus 2 negative controls.
+- Runtime stability: 1/1.
+- Bundle/security checks: 5/5.
+- Page breakage regressions: 0 observed.
+- Ordinary blocking regressions: 0 observed after separating ordinary fixture
+ targets from detector bait.
+
+## Stealth fixture
+
+The local mechanism-equivalent detector executes normally. The bait exists,
+retains positive `offsetHeight`, `clientHeight`, and bounding-rect dimensions,
+keeps non-hidden computed display/visibility and child structure, survives a
+timed re-check and reinsertion, while the synthetic advertising script and
+fetch probe remain blocked and no ad content loads.
+
+## Performance
+
+- Indexed startup index: 494 bytes.
+- Relevant per-frame load for the YouTube sample: 1,784,162 bytes.
+- Relevant page-plane parse: 9.03 ms.
+- Mutation benchmark: 0.153291 ms for 2,000 checks.
+- Domain shards: 339; early shards: 338.
+- Full bundle parse per frame: no.
## Real-world status
-- CanYouBlockIt live result: `NOT_OBSERVED`.
-- No detector script was blocked, hidden, spoofed, or replaced in the local
+- CanYouBlockIt live result: `NOT_OBSERVED`; manual clean-profile validation is
+ still required and was intentionally not performed in this run.
+- No detector script was hidden, blocked, spoofed, or replaced in the local
acceptance fixture.
-- The final live CanYouBlockIt comparison still requires a manual clean-profile
- run: ADAPT off must report blocker OFF, and ADAPT on must still report blocker
- OFF while ad requests remain blocked and visible ads remain absent.
-- YouTube: `NOT_OBSERVED`; no genuine live ad occurrence was tested.
+- YouTube live ad result: `NOT_OBSERVED`.
+- GitHub Actions: pending the post-push workflow result.
## Release status
-Do not merge PR #2. Technical local acceptance is green, but licensing review
-and the manual CanYouBlockIt/clean-profile live acceptance remain release gates.
+Do not merge PR #2. The duplicate cosmetic-plane P0 is removed and the local
