A mutable `HEAD` reference is not sufficient for a reproducible security contract. +### Browser fingerprinting and presentation identity + +RFC 6973 defines a fingerprint as information elements that identify a device +or application instance and recommends data minimization and meaningful +anonymity sets. Browser-fingerprinting research shows that browser, operating +system, graphics, processor, and other host characteristics can support +identification across browsers. The W3C Privacy Working Group's 2025 guidance +therefore recommends limiting unnecessary entropy and generally prefers +standardized or null values over randomization, because independently varied +values can reduce usability and introduce new distinguishers. + +OriginWeave consequently separates privacy-preserving presentation +normalization from block evasion. The Rust kernel accepts only bounded, +internally consistent profiles and standardizes its first named time-zone +surface to `UTC`; a future Chromium adapter must apply all claimed surfaces +before page script and prove that no ambient host value leaks. Camoufox is +reviewed only as implementation precedent for native-layer consistency, not as +policy authority for anti-detect, CAPTCHA, or access-control circumvention. + ### Extension-to-Agent grant origin binding RFC 6454 defines a web origin as the scheme, host, and port tuple that browsers use to isolate authority. An OriginWeave `extension_grant` that is bound only to extension identity, session, and browsing context would remain valid after the same context navigates to another origin. OriginWeave therefore requires the grant and the request to carry the same canonical origin. A host change or a non-default port change is a different origin and cannot reuse the grant. This is grant-scope isolation only; it does not install an extension, parse Chrome messages, or mint Agent capabilities from Manifest V3 permissions. @@ -122,10 +141,14 @@ Berners-Lee, T., Fielding, R., & Masinter, L.

Compared with the prior **2026-08-24 158-PR snapshot**, the queue is 49 PRs smaller.

They grant no origin, + destination, transport, extension, secret, approval, or agent-action right. +- An eventual Chromium adapter must prove that its low- and high-entropy UA-CH + values and request headers are coherent with the selected presentation + profile before page script can observe them. Until that adapter evidence + exists, this metadata contract must not be described as shipped browser + anti-fingerprinting or anti-detection behavior. +- Access-control, CAPTCHA, consent, and bot-management outcomes remain external + policy decisions. This contract never treats a challenge as something to + bypass. + +## Options considered + +- **Expose host hint values:** rejected because on-disk architecture, bitness, + and model strings are re-identifying. +- **Randomize hint values per session:** rejected because W3C guidance warns + fresh random values can be more distinguishing and are not reproducible. +- **Provide bounded enumerated classes and enforce the spec's coherence + rules:** selected. + +## Decision + +OriginWeave will model UA Client Hints in the Rust fingerprint kernel using +bounded, enumerated classes plus the spec's cross-field coherence rules. This +slice adds: + +- `UaBrand` — validates one non-empty brand/version pair. Brand names admit + ASCII alphanumerics plus the separator bytes used by the WICG GREASE brand + algorithm (`SP`, `(`, `)`, `-`, `.`, `/`, `:`, `;`, `=`, `?`, `_`), so + values such as `Google Chrome`, `Not/A)Brand`, and `Not_A Brand` remain + representable. Versions are non-empty dotted ASCII alphanumeric strings. + Brand names and versions are each capped at 32 ASCII bytes as OriginWeave + resource bounds; neither ceiling is a UA Client Hints specification limit. +- `HintsArchitecture` (`x86`, `arm`) and `HintsBitness` (`32`, `64`) — bounded, + enumerated architecture/bitness tokens. +- `HintsPlatform::normalize` — maps to `Windows`, `macOS`, `Linux` and rejects + any other token. +- `UaClientHints::new` — requires one through 16 validated brands, requires an + empty `model` when `mobile` is false per the draft's processing model, and + caps a mobile model at 64 UTF-8 bytes. The 16-brand and 64-byte model limits + are OriginWeave resource bounds rather than UA Client Hints specification + limits. + +Admission checks are a control-plane contract only; they do not install a +browser or override real headers. + +## Consequences + +The fingerprint container gains a deterministic, testable UA-CH surface which +is purely a contract. No real browser is yet claimed: a future pinned Chromium +adapter must apply every listed hint surface before page script and prove no +ambient host value leaks. This does not make stealth or anti-detection a +shipped browser capability. + +## Failure and degraded behavior + +Construction rejects unknown architecture/bitness/platform tokens, over-length +brand names or versions, empty brand names or versions, brand bytes outside the +bounded compatibility set, version bytes outside dotted ASCII alphanumeric +syntax, over-length mobile model values, an empty brand list, a brand list with +more than 16 entries, and a non-mobile set with a non-empty model. The +non-mobile empty-model coherence rule is checked before the local model-size +ceiling so a contradictory non-mobile identity retains its semantic failure +class even when its model string is also too long. + +## Security, privacy, and governance impact + +Hints are identity evidence only and grant no origin, transport, extension, +secret, or action authority. Deterministic checks make adapter claims +auditable. The admitted brand-name separators are a reviewed compatibility +set from the current WICG GREASE algorithm rather than an unbounded printable +ASCII allowance; quote, backslash, controls, and Unicode remain rejected. The +32-byte brand/version, 16-entry brand-list, and 64-byte mobile-model ceilings +are local resource budgets and must not be presented as requirements of the +WICG specification. + +## Tests and acceptance evidence + +`ua_client_hints_surface.rs` exercises each surface: ordinary and realistic +Chromium/GREASE brand names, empty and invalid brand/version values, the local +brand-name and brand-version length bounds, every architecture/bitness/platform +token and its rejection, empty brand lists, the 16-entry retained brand-list +boundary, the mobile-model resource bound, mobile with model, and non-mobile +with model including semantic-error precedence. The workspace coverage gate +enforces 100% functions, lines, regions, and branches. Browser acceptance +remains out of scope. + +## Migration and rollback + +The new types are additive and do not change existing `PresentationProfile` +digests. Within this proposed branch, the constructors now reject brand +versions above 32 ASCII bytes, brand lists above 16 entries, and mobile models +above 64 UTF-8 bytes instead of retaining unbounded presentation strings or +lists. Rollback removes the UA Client Hints types and tests without schema +changes. + +## Open follow-ups + +- A real pinned-Chromium adapter that applies the full brand/version list, + low- and high-entropy hint set, and platform coherence before page script. +- A release-time acceptance test that cannot read the host architecture or + bitness. + +## Supersession / reversal conditions + +This ADR is superseded if a later reviewed decision defines a different +UA Client Hints presentation model, adds a cohort-backed default selection +contract, or moves the authoritative coherence boundary into a pinned browser +adapter with equivalent fail-closed evidence. It is reversed if OriginWeave +stops claiming a bounded UA-CH presentation surface and removes these types +and tests without a replacement. + +## References + +Web Platform Incubator Community Group.

OriginWeave Protocol versioning remains independent and cannot be changed by MCP metadata. +PR #293 is a separate active, stacked browser-adapter slice on top of presentation-identity prerequisite #229. It introduces a narrow `originweave-bidi` capability boundary pinned to the 18 August 2026 WebDriver BiDi Working Draft. The capability map delegates complete-profile admission to `originweave-fingerprint` and intentionally excludes `HardwareConcurrency` and `Platform`: current standard BiDi cannot represent those complete Chromium presentation surfaces, so standard BiDi alone must return the kernel's `MissingSurface(HardwareConcurrency)` result rather than accept ambient host values. This branch-local slice does not send WebDriver BiDi commands, create a generic DevTools pass-through, apply a profile to Chromium, or produce page-observed presentation evidence. Those remain #292 follow-up work and require exact-head verification plus a version-pinned Chromium/CDP adapter for the Chromium-only remainder. + ## Consequences OriginWeave carries adapter maintenance and version negotiation but gains a durable customer API. Multiple browser/control transports can coexist. New upstream capabilities do not silently change risk or action semantics. Compatibility matrices become release artifacts. ## Failure and degraded behavior -Adapter negotiation failure disables only affected capabilities. Unsupported or schema-incompatible messages fail closed with typed errors. OriginWeave must not bypass a failed adapter by exposing raw CDP or arbitrary JavaScript to an autonomous model. A standards adapter may fall back to a pinned vendor adapter only when the same OriginWeave semantic and security contract is proven. +Adapter negotiation failure disables only affected capabilities. Unsupported or schema-incompatible messages fail closed with typed errors. OriginWeave must not bypass a failed adapter by exposing raw CDP or arbitrary JavaScript to an autonomous model. A standards adapter may fall back to a pinned vendor adapter only when the same OriginWeave semantic and security contract is proven. A partial presentation-emulation capability set is unsupported for complete-profile admission; it cannot be completed with ambient browser values. ## Security / privacy / governance impact Protocol validation occurs before messages influence policy. Tool/page-provided strings remain untrusted. Method and tool routing metadata is shape-bounded before correlation, preventing malformed or oversized untrusted routing strings from being reinterpreted through mismatch handling. Secret handles never become raw secret protocol payloads; only the separately authorized trusted broker-to-browser delivery path may materialize the value, and that value does not pass through MCP, WebMCP, BiDi observation, or model-visible CDP output. Adapter version/provenance is recorded for audit and incident reconstruction. +For presentation emulation, protocol availability is not presentation evidence. The adapter must bind its capability claim to an explicit protocol/browser revision, fail closed on missing required surfaces, and later prove page-visible state after application. Neither a protocol command acknowledgement nor an unobserved browser setting is sufficient evidence. + ## Tests and acceptance evidence Require version-negotiation tests, schema/property tests, malformed-message tests, BiDi/CDP semantic parity tests for shared capabilities, WebMCP prompt-injection tests, MCP authority-separation and version-change tests, browser-version compatibility matrices, and end-to-end proof that unsupported capabilities fail without side effects. For the protected-main `tools/call` foundation, acceptance includes deterministic method and tool-name bounds/syntax, exact header/body method and tool-name correlation only after both sides are bounded, explicit invalid-method/invalid-tool-name/unknown-tool rejection, one unambiguous tool-to-action registry, independent capability/risk expectations, route/action mismatch denial before ordinary policy evaluation, exact 100% owned-production coverage, and integrated review evidence from PR #168. For active PR #170, exact-current acceptance additionally requires bounded protocol metadata before cross-field comparison, required client-capabilities presence, bounded `tools/list` method correlation, rejection of unissued cursors, deterministic result/cache semantics, exact 100% owned-production coverage, and unchanged-head CI/security/review evidence. These checks do not substitute for complete transport or adapter conformance. +For PR #293, acceptance of this first capability-boundary slice requires a regression that fails on #229 because no `originweave-bidi` bounded context or pinned presentation-capability map exists, then exact-head Rust/Python/rustdoc/Clippy/coverage verification that the minimal adapter compiles and that the pinned standard set fails with the canonical fingerprint-kernel missing-surface error. This is not acceptance of #292 as a whole. Real pinned-Chromium application, page-observed post-condition evidence, navigation/renderer/crash/cleanup behavior, and the Chromium-only CDP remainder still require realistic browser E2E. + ## Migration and rollback Adapters are independently versioned and can be canaried. Clients migrate through OriginWeave Protocol compatibility rules, not upstream protocol rewrites. Rollback pins a previously supported adapter/browser/protocol pair and records that pair in provenance. ## Open follow-ups -Define internal protocol versioning rules, adapter capability descriptors, minimum supported BiDi level, CDP pin policy, complete MCP Streamable HTTP/request-metadata validation, MCP transport serialization, authenticated deployment, and MCP/WebMCP schema isolation. +Define internal protocol versioning rules, complete MCP Streamable HTTP/request-metadata validation, MCP transport serialization, authenticated deployment, and MCP/WebMCP schema isolation.

Reduced motion remains an expressible protocol capability but is excluded from the reusable plan because the standard cannot selectively restore prior media state; no caller-mintable exclusive-reset type substitutes for Browser Session lifecycle evidence. Planning does not send a command, create an acknowledgement, apply or prove cleanup of a profile, or produce page-observed evidence.

OriginWeave did not expose that standard operation in its typed planning boundary. -This is a narrower gap than the complete `PresentationSurface::Screen` requirement. `ScreenMetrics` includes width, height, and color depth, but the WebDriver BiDi `screenArea` payload controls only width and height. Advertising the complete Screen surface after adding this command would therefore create a false-green admission path. +The operation is not merely a narrower version of `PresentationSurface::Screen`. WebDriver BiDi applies one `screenArea` rectangle to both the web-exposed total screen area and the web-exposed available screen area. OriginWeave `ScreenMetrics` currently models width, height, and color depth, but not `screen.availWidth` or `screen.availHeight`. Automatically deriving the command from `ScreenMetrics` inside the reusable profile plan would therefore mutate a page-observable fingerprint surface that the profile neither selected nor digest-bound. Color depth remains independently uncontrolled as well. ## Constraints - Keep browser-domain truth in OriginWeave; WebDriver BiDi remains an adapter, not policy authority. - Preserve the runtime-qualified 3 September 2026 Working Draft pin. Publication freshness is owned separately by `webdriver-bidi-publication-current.md`. - Reuse validated presentation value objects rather than reopen raw width/height validation in the adapter. -- A reusable browsing context may plan only overrides with a context-scoped, non-destructive reset. +- A reusable browsing context may automatically plan only observables represented by the explicit presentation contract and paired with a context-scoped, non-destructive reset. - Do not add media-feature cleanup, ambient-host fallback, live protocol I/O, command-ACK success semantics, or Chromium-specific authority here. ## Alternatives -1. **Keep screen area unplanned.** Rejected because the qualified standard already provides an independently resettable screen-area operation and omitting it leaves a useful standard capability unused. -2. **Mark `PresentationSurface::Screen` supported after planning width/height.** Rejected because color depth remains page-observable and uncontrolled. -3. **Carry full `ScreenMetrics` in the command payload.** Rejected because the command would then contain a field the protocol operation does not apply, making evidence and later serialization authority ambiguous. -4. **Project a dedicated `WebDriverBidiScreenArea` from validated `ScreenMetrics`.** Selected.

Although `screenArea: null` provides a symmetric reset, the apply operation also changes the currently unmodelled available-screen rectangle. Reversibility alone does not authorize an additional page observable. +2. **Mark `PresentationSurface::Screen` supported after planning width/height.** Rejected because color depth remains page-observable and uncontrolled, and available-screen geometry is absent from the profile. +3. **Carry full `ScreenMetrics` in the command payload.** Rejected because the command would contain color depth, which the protocol operation does not apply, while still failing to name the available-screen side effect. +4. **Expose an explicit coupled screen-area partial intent and keep it out of the reusable profile-derived plan.** Selected. `WebDriverBidiScreenArea` projects validated width/height, documents that the same rectangle becomes both total and available screen area, and has a separate context-scoped reset.

The format follo ## [Unreleased] -- Extended the reusable WebDriver BiDi presentation planner with a context-scoped `emulation.setScreenSettingsOverride` screen-area intent and matching reset, alongside viewport/DPR and timezone. The adapter projects only validated width and height into a dedicated `WebDriverBidiScreenArea`; color depth remains uncontrolled, so complete `PresentationSurface::Screen` admission still fails closed instead of treating screen geometry as the whole screen fingerprint surface. +- Exposed WebDriver BiDi `emulation.setScreenSettingsOverride` as a separately explicit, context-scoped partial screen-area intent with matching reset. The protocol couples total and available screen areas to one rectangle, while the current presentation profile does not model `screen.availWidth` / `screen.availHeight`; the reusable profile-derived planner therefore remains viewport/DPR plus timezone rather than silently mutating an unmodelled page observable. - Refreshed the product-gap queue to 126 open pull requests (54 ready, 72 draft) after #190, #188, #185, #192, #182, #184, #115, #181, #116, #117, #118, #183, #114, #127, #112, #109, #186, #110, #108, #111, #174, and #113 were merged into their immediate stacked prerequisites. PRs #147, #146, #145, #144, #143, #142, #141, #139, #136, #132, #129, and #128 moved to ready after exact-head checks and thread review; these are queue-consolidation results, not protected-main shipment. ### Fixed +- Prevented the reusable profile-derived WebDriver BiDi planner from scheduling `setScreenSettingsOverride` from `ScreenMetrics` alone, because the standard operation also changes the page-observable available screen rectangle that the current presentation identity neither selects nor digest-binds. - Restored canonical Rust formatting for the WebDriver BiDi presentation cleanup assertion so exact-head contracts can execute the test, Clippy, and rustdoc gates. ### Added -- Added a version-pinned `originweave-bidi` presentation-capability boundary for the W3C WebDriver BiDi Working Draft published on 3 September 2026 (`https://www.w3.org/TR/2026/WD-webdriver-bidi-20260903/`). It depends inward on `originweave-fingerprint`, plans the symmetrically restorable screen-area, viewport/DPR, and timezone commands for one bounded reusable browsing context, and still fails first on the complete screen surface because standard BiDi screen-area emulation cannot prove color depth or ordered languages. Reduced motion remains an expressible protocol capability but is not installed by the reusable plan because standard cleanup cannot selectively restore prior media state. No caller-mintable exclusive-reset type is exposed; a Browser Session owner must prove a disposable lifecycle or complete prior-state restoration. Planning performs no transport I/O or acknowledgement, cleanup, ownership, or page-observed evidence. Hardware concurrency and the complete Chromium platform/User-Agent Client Hints surface still require a separate versioned Chromium adapter. +- Added a version-pinned `originweave-bidi` presentation-capability boundary for the W3C WebDriver BiDi Working Draft published on 3 September 2026 (`https://www.w3.org/TR/2026/WD-webdriver-bidi-20260903/`).

The ordinary `plan_standard_presentation_commands` and `plan_standard_presentation_cleanup` remain limited to viewport/DPR and time zone because those are the currently modelled, reusable-plan observables with symmetric resets. +`originweave-bidi` retains `WebDriverBidiScreenArea` as the validated width/height projection and retains explicit `SetScreenArea` / `ResetScreenArea` command intent. Both command variants and both explicit planner functions require `WebDriverBidiScreenAreaOwnership` rather than a raw `WebDriverBidiBrowsingContext`. -`WebDriverBidiScreenArea` can only be derived from validated `ScreenMetrics`; its documentation records that WebDriver BiDi couples total and available screen areas to the same rectangle. The complete capability map intentionally continues to omit `PresentationSurface::Screen`, so `require_complete_presentation_profile()` still returns `MissingSurface(Screen)` until a reviewed owner models the available-screen observable and controls color depth as well. +`WebDriverBidiScreenAreaOwnership` contains the exact validated browsing context but intentionally has no public constructor. The adapter therefore cannot mint its own proof from a context identifier. A future Browser Session integration may create the witness only after proving an exclusive/disposable lifecycle or an equivalent ownership transition. Possession of the witness is the authority to plan both the apply and matching cleanup for that owned lifecycle; it is not transport acknowledgement or page-observed evidence. -The planner produces typed intent only. Transport execution, page-observed post-conditions, browser/session cleanup evidence, crash recovery, and the remaining Chromium-only presentation surfaces stay with the existing #292/#299 acceptance path and its canonical runtime owners. +The ordinary `plan_standard_presentation_commands` and `plan_standard_presentation_cleanup` remain limited to viewport/DPR and time zone.

+OriginWeave's WebDriver BiDi presentation adapter now requires opaque ownership witnesses before it can plan viewport/device-pixel-ratio, timezone, or screen-area mutation. That closes a dangerous adapter-level gap: a caller that merely knows a browsing-context identifier cannot overwrite another owner's presentation state and later clear it to an implementation default. + +The remaining gap is upstream of the adapter. A production Browser Session must establish why a context is exclusively OriginWeave-owned before any presentation-mutation authority can be issued. Without that lifecycle, a hidden constructor or driver shortcut would simply reintroduce ambient authority under a different type name. + +The 9 September 2026 WebDriver BiDi Working Draft provides a suitable standards-aligned isolation mechanism. `browser.createUserContext` creates a new user context. `browsingContext.create` can create a browsing context inside a selected user context. `browser.removeUserContext` closes that user context and every navigable in it without running `beforeunload` handlers. These protocol operations are adapter capabilities; they do not themselves define OriginWeave's domain ownership or prove cleanup merely because a command was acknowledged. + +## Decision drivers + +- A remote-issued browsing-context identifier is addressability, not mutation authority. +- Shared or attached human contexts must never acquire disposable-owner semantics by implication. +- Presentation reset must not destroy a predecessor override owned by another task/session. +- Navigation, renderer replacement, crash, cleanup failure, and transport loss must invalidate stale authority. +- The Browser Session domain must remain independent of WebDriver BiDi, CDP, MCP, and LLM policy decisions. +- An adapter acknowledgement is not a successful cleanup post-condition. + +## Assumptions and authority boundaries + +`originweave-browser-session` owns Browser Session lifecycle state, owned-context membership, monotonic context epochs, and opaque presentation-mutation authority. It consumes validated `BrowserSessionId` and `BrowsingContextId` values from `originweave-core`. + +A narrow `DisposableContextPort` is the anti-corruption boundary to a future browser adapter. The port may be implemented with WebDriver BiDi user contexts, a separately reviewed Chromium path, or another released adapter, but the adapter does not become the policy or ownership authority. + +The first implementation deliberately does not convert `PresentationMutationAuthority` into the WebDriver BiDi crate's private presentation/screen-area witnesses. That bridge belongs to a later integration slice after both sides' contracts are reviewed. It also does not claim real-Chromium cleanup evidence. + +## Options considered + +### A. Treat any known browsing context as owned + +Rejected. It recreates the original authority-confusion defect and allows one task to erase another task's predecessor state. + +### B. Snapshot every predecessor presentation override and restore it exactly + +Deferred. Exact predecessor capture can support reusable/attached contexts later, but today OriginWeave does not have a complete standard protocol snapshot for every governed presentation surface. Partial restoration would be a false safety claim. + +### C. Own a disposable isolated context lifecycle and issue opaque authority only after creation + +Selected for the first production slice. Isolation gives the aggregate a tractable ownership invariant and a clear terminal action: destruction of the task-owned context boundary. A future WebDriver BiDi adapter should normally map this to a fresh user context plus a browsing context created inside it, then remove the user context during cleanup. + +## Decision + +Introduce `originweave-browser-session` as an independent Rust bounded context with these invariants: + +1. `BrowserSession` is the aggregate root. It begins `Active` and may end normally only after every owned disposable context has proven destruction. +2. A context enters the aggregate's owned set only after `DisposableContextPort::create_disposable_context` succeeds. Supplying a raw `BrowsingContextId` never creates ownership. +3. Successful owned-context creation mints a non-caller-constructible `PresentationMutationAuthority` bound to the exact browser session, browsing context, and context epoch. +4. Advancing the context epoch invalidates previously issued authority. The adapter integration must use this transition at navigation/renderer lifecycle boundaries that invalidate the prior authority scope. +5. Destruction requires exact current authority. A stale, foreign-session, unknown, already-destroyed, or uncertain context fails closed. +6. If destruction cannot be proved, the context becomes `Uncertain` and its authority is invalidated. Normal session end is prohibited. +7. Transport loss moves the Browser Session to `TransportLost`, marks still-active owned contexts uncertain, and prevents further authority issuance. +8. Epoch sequence numbers are monotonic authority identities, not business counters; gaps are allowed after failed creation or rejected duplicate adapter output. + +## Consequences + +Browser Session ownership becomes a domain fact rather than an adapter convention. This gives the future BiDi/Chromium bridge a legitimate place to mint presentation witnesses without making raw driver identifiers authoritative. + +The first slice remains intentionally incomplete for buyer acceptance. No real Chromium user-context adapter, presentation-witness bridge, observed cleanup receipt, crash-recovery reconciliation, or #299 full browser replay is claimed here. + +## Failure and degraded behavior + +Creation failure produces no authority. A duplicate context returned by a supposedly fresh-context adapter is rejected and is not automatically destroyed, because destroying that identifier could target another owner's context. Destruction failure and transport loss quarantine the affected lifecycle rather than assuming cleanup. Once a Browser Session is `Ended` or `TransportLost`, creation, authority lookup, destruction, and normal end transitions that require an active session fail closed. + +## Security / privacy / governance impact + +Disposable context ownership reduces cross-task presentation-state interference and is compatible with isolated Agent Task profiles. It is not a substitute for Chromium sandboxing, egress policy, origin capability policy, Keyverse secret handling, or evidence retention controls. Those remain with their canonical owners. + +No page-controlled value, secret, provider/model choice, or LLM result can mint Browser Session authority. + +## Tests and acceptance evidence + +The owning crate tests hostile raw-context lookup, creation failure, duplicate adapter output, epoch exhaustion, stale authority, cross-session authority, cleanup failure, transport loss, unknown context, epoch advancement, and successful destroy-before-end behavior. Repository contracts require the bounded context to be a workspace member. + +Exact-head CI, Clippy, rustdoc, function/line/region/branch coverage and independent review remain required before integration. Real-browser acceptance is deferred to a later adapter slice and must prove creation, page-observed mutation, cleanup/destruction and post-cleanup isolation in pinned Chromium; command ACK alone is not success. + +## Migration and rollback + +This is additive. Until a reviewed adapter bridge consumes the new authority, existing presentation code remains fail closed behind its private ownership witnesses. Rollback removes the new crate, workspace/lockfile entries, tests and Proposed ADR without changing protected Chromium or central workflow policy. + +## Open follow-ups + +- Implement the WebDriver BiDi disposable-user-context adapter using the runtime-qualified protocol contract. +- Define the narrow conversion/ACL from `PresentationMutationAuthority` to BiDi presentation/screen-area ownership witnesses without exposing public constructors. +- Specify observed destruction/reconciliation after browser crash or transport loss. +- Replay #299 with three complete real-Chromium trials after the canonical sandbox/runtime owner path is usable. +- Evaluate exact predecessor capture/restore only if attached/reusable contexts become a buyer requirement. + +## Supersession / reversal conditions + +Supersede this ADR if WebDriver/Chromium gains a complete, queryable and exactly restorable predecessor-state contract for all governed presentation surfaces, or if OriginWeave adopts another isolation primitive with equivalent ownership and destruction evidence.

Owns the narrow WebDriver BiDi adapter contract that is expressible by one explicit specification revision. The active slice pins the W3C WebDriver BiDi Working Draft published on 3 September 2026 at `https://www.w3.org/TR/2026/WD-webdriver-bidi-20260903/` and delegates complete-profile admission back to `originweave-fingerprint`. Standard BiDi covers viewport, device-pixel-ratio, timezone, and reduced-motion surfaces. Its width/height screen command cannot prove the kernel's complete screen-and-color-depth surface, and its single locale cannot prove ordered language preferences; hardware concurrency and the complete Chromium platform/User-Agent Client Hints surface also remain outside the standard set. The adapter therefore fails first on `Screen` rather than inheriting ambient Chromium values. It can plan two typed reusable-context commands—viewport/DPR and timezone—for one bounded opaque browsing-context identifier. Reduced motion remains an expressible protocol capability, but the reusable plan does not install it because `features: null` removes the target's complete media-feature override configuration rather than restoring prior state. Generic cleanup therefore resets only viewport/DPR and timezone. No caller-mintable exclusive-reset type is exposed; a Browser Session owner must instead prove a disposable context lifecycle or restore the complete prior media configuration. Planning sends nothing and proves neither acknowledgement, cleanup, ownership, nor page-visible state. Transport, post-condition observation, and reusable-context media restoration require the pinned Chromium/BiDi path and, for Chromium-only surfaces, a separate versioned `originweave-cdp` adapter. +### `originweave-browser-session` (active PR) + +Owns the Browser Session aggregate boundary for disposable context lifecycle and presentation-mutation authority.

Stale or foreign authority fails closed; failed destruction makes the context uncertain; browser transport loss invalidates active authority; and normal session end is rejected until every owned context has proven destruction. + +This active slice deliberately stops before browser transport.

This gives the future BiDi/Chromium bridge a legitimate place to mint presentation witnesses without making raw driver identifiers authoritative. + +The Browser Session domain relies on an explicit adapter proof obligation for global live-lifetime non-aliasing of `DisposableIsolationId`.

No real Chromium user-context adapter, presentation-witness bridge, observed cleanup receipt, crash-recovery reconciliation, or #299 full browser replay is claimed here. ## Failure and degraded behavior -Creation failure produces no authority. A duplicate context returned by a supposedly fresh-context adapter is rejected and is not automatically destroyed, because destroying that identifier could target another owner's context. Destruction failure and transport loss quarantine the affected lifecycle rather than assuming cleanup. Once a Browser Session is `Ended` or `TransportLost`, creation, authority lookup, destruction, and normal end transitions that require an active session fail closed. +Creation failure produces no authority. Duplicate browsing-context or disposable-isolation identities returned inside one aggregate are rejected and are not automatically destroyed, because a port that violates the fresh-boundary contract may have returned another owner's state. Cross-aggregate aliasing is prevented by requiring authority and destruction to carry the distinct isolation identity. Destruction failure and transport loss quarantine the affected lifecycle rather than assuming cleanup. Once a Browser Session is `Ended` or `TransportLost`, creation, authority lookup, destruction, and normal end transitions that require an active session fail closed. ## Security / privacy / governance impact Disposable context ownership reduces cross-task presentation-state interference and is compatible with isolated Agent Task profiles.

No real Chromium user-context adapter, presentation-witness bridge, observed cleanup receipt, crash/recovery reconciliation, or #299 full browser replay is claimed here. ## Failure and degraded behavior -Creation failure produces no authority. Duplicate browsing-context or disposable-isolation identities returned inside one aggregate are rejected and are not automatically destroyed, because a port that violates the fresh-boundary contract may have returned another owner's state. Cross-aggregate aliasing is prevented by requiring authority and destruction to carry the distinct isolation identity. Destruction failure and transport loss quarantine the affected lifecycle rather than assuming cleanup. Once a Browser Session is `Ended` or `TransportLost`, creation, authority lookup, destruction, and normal end transitions that require an active session fail closed. +`CreateFailedClean` produces no authority and permits continued active operation because the adapter has proved that no disposable boundary exists. `CreateFailedUncertain` and duplicate adapter output move the Browser Session to `RecoveryRequired`; existing active records become uncertain and normal completion is blocked. Duplicate output is never automatically destroyed because a contract-violating adapter may have returned another owner's state. Destruction failure marks the affected record uncertain. Transport loss uses the separate `TransportLost` state. Once a Browser Session is `Ended`, `TransportLost`, or `RecoveryRequired`, creation, authority lookup, destruction, epoch advancement, and normal end transitions that require an active session fail closed. ## Security / privacy / governance impact -Disposable context ownership reduces cross-task presentation-state interference and is compatible with isolated Agent Task profiles.

An adapter cannot report destruction failure from creation or creation failure from destruction, so the aggregate no longer has to interpret an impossible phase transition as a degraded case. + The Browser Session domain relies on an explicit adapter proof obligation for global live-lifetime non-aliasing of `DisposableIsolationId`. For WebDriver BiDi that proof is the standard's unique user-context identifier plus adapter conformance tests that preserve the mapping and remove the exact user context. A generic random adapter token without a verified one-to-one browser lifecycle mapping is not sufficient. The slice remains incomplete for buyer acceptance. No real Chromium user-context adapter, presentation-witness bridge, observed cleanup receipt, crash/recovery reconciliation, or #299 full browser replay is claimed here. ## Failure and degraded behavior -`CreateFailedClean` produces no authority and permits continued active operation because the adapter has proved that no disposable boundary exists. `CreateFailedUncertain`, duplicate adapter output, and unproven destruction move the Browser Session to `RecoveryRequired`; existing active records become uncertain and all active-only transitions are blocked. Duplicate output is never automatically destroyed because a contract-violating adapter may have returned another owner's state. A failed destroy preserves the exact failed handle as uncertain evidence; it is not retried implicitly and no later adapter I/O is admitted from that aggregate. Transport loss uses the separate `TransportLost` state. Once a Browser Session is `Ended`, `TransportLost`, or `RecoveryRequired`, creation, authority lookup, destruction, epoch advancement, and normal end transitions that require an active session fail closed. +`DisposableContextCreateError::CreateFailedClean` produces no authority and permits continued active operation because the adapter has proved that no disposable boundary exists. `DisposableContextCreateError::CreateFailedUncertain`, duplicate adapter output, and any `DisposableContextDestroyError` move the Browser Session to `RecoveryRequired`; existing active records become uncertain and all active-only transitions are blocked.

The active implementation carries a separate non-aliasing disposable isolation identity through authority validation and destruction I/O. +The Browser Session boundary must establish why a context is exclusively OriginWeave-owned before presentation authority exists. External browser-session, user-context/isolation, and browsing-context identifiers are protocol addressability. They may be reused after a prior lifecycle ends, so `(BrowserSessionId, DisposableIsolationId, BrowsingContextId, local epoch)` is not by itself a durable capability generation. -A second lifecycle gap appears whenever the adapter does not have a proved-clean post-condition. During creation, an adapter can fail after browser state may already have been created, or can return a duplicate context/isolation identity. During destruction, an adapter can fail after the cleanup command has been sent without proving that the exact owned boundary is gone. In either case OriginWeave cannot safely keep the aggregate `Active`: further authority issuance would continue operating beside unresolved browser state. Creation and destruction therefore require explicit clean-versus-uncertain handling and a recovery-required state. +Lifecycle failures also need lossless evidence. A BiDi adapter can successfully create a user context before later browsing-context creation or verification becomes uncertain. Duplicate adapter output can expose an offending handle that must not be silently discarded or automatically destroyed. Destruction can fail without proving that the exact isolation boundary is gone. These outcomes require recovery quarantine while retaining every exact browser-issued identity that is already known. -The 9 September 2026 WebDriver BiDi Working Draft provides a standards-aligned isolation identity. A user context has a user-context id defined as a unique string set when the user context is created. `browser.createUserContext` creates a new user context, `browsingContext.create` can create a browsing context inside it, and `browser.removeUserContext` removes that user context after closing its navigables. These protocol operations are adapter capabilities; they do not themselves define OriginWeave policy authority, and a command acknowledgement alone is not cleanup proof. +Transport liveness is independent from ownership certainty. A session already in `RecoveryRequired` can subsequently lose its transport; that new fact must be recorded without erasing the recovery evidence. Conversely, merely entering recovery does not prove the transport is dead. -## Decision drivers - -- Remote-issued browser-session and browsing-context identifiers are addressability, not mutation authority. -- Reuse of external session/context identifiers across aggregate incarnations must not create authority aliasing. -- Shared or attached human contexts must never acquire disposable-owner semantics by implication. -- Presentation reset must not destroy a predecessor override owned by another task/session. -- Destruction I/O must be scoped by the exact disposable isolation boundary, not reconstructed from aliasable session/context identifiers. -- Creation failure must distinguish proved-clean failure from an uncertain post-condition. -- Creation-only and destruction-only adapter failures must be different types so phase-invalid outcomes are not representable. -- Duplicate or partial-create outcomes must not permit false normal completion. -- An unproven destroy must quarantine the aggregate before any later context creation or authority issuance. -- Navigation, renderer replacement, crash, cleanup failure, and transport loss must invalidate stale authority. -- The Browser Session domain must remain independent of WebDriver BiDi, CDP, MCP, and LLM policy decisions. -- An adapter acknowledgement is not a successful cleanup post-condition. +The 9 September 2026 WebDriver BiDi Working Draft defines user-context identifiers and the `browser.createUserContext`, `browsingContext.create`, and `browser.removeUserContext` lifecycle. Those commands remain adapter capabilities rather than OriginWeave policy authority, and command ACK alone is not destruction proof. -## Assumptions and authority boundaries - -`originweave-browser-session` owns Browser Session lifecycle state, owned-context membership, monotonic context epochs, validated disposable-isolation identity, recovery-required state, and opaque presentation-mutation authority. It consumes validated `BrowserSessionId` and `BrowsingContextId` values from `originweave-core`. +## Decision drivers -A narrow `DisposableContextPort` is the anti-corruption boundary to a future browser adapter. The port must return a `DisposableContextHandle` containing the browsing-context address and a live-lifetime non-aliasing `DisposableIsolationId`. For WebDriver BiDi, the adapter proof obligation is a one-to-one mapping from that isolation id to the specification-defined unique user-context id returned by fresh user-context creation. The same handle must scope destruction; reconstructing cleanup authority from `(BrowserSessionId, BrowsingContextId)` is forbidden. +- Raw WebDriver/BiDi identifiers are addressability, not mutation or cleanup authority. +- Sequential aggregate recreation must not make a retained stale authority valid again. +- The lifecycle adapter must receive the same non-reused session incarnation used by authority validation; an aggregate-only nonce is insufficient. +- Known remote identities from partial creation, duplicate output, or unproven destruction must be retained as recovery evidence without becoming command authority. +- Ownership recovery and transport liveness must remain orthogonal. +- Duplicate or uncertain outcomes fail closed and must not permit false normal completion. +- Destruction I/O must use the exact stored handle and session incarnation rather than reconstructing authority from raw identifiers. +- Browser Session remains the domain authority; WebDriver BiDi, CDP, MCP, and LLMs remain adapters or consumers. -Creation and destruction expose separate failure types. `DisposableContextCreateError::CreateFailedClean` is valid only when the adapter can prove that no disposable browser state was created. `DisposableContextCreateError::CreateFailedUncertain` is required after any partial-create or unknown post-condition. An uncertain outcome moves the aggregate to `RecoveryRequired`, invalidates active owned-context authority, blocks further creation/authority issuance, and prevents normal `end()` until a separate reconciliation design proves what happened remotely. A destruction-only failure is not representable from the creation method. +## Decision -Destruction returns `DisposableContextDestroyError`. Its failure means destruction could not be proved: the exact record becomes uncertain and the whole aggregate moves to `RecoveryRequired`; every remaining active context becomes uncertain and all active-only transitions fail before further adapter I/O. Creation-only failures are not representable from the destruction method. The current slice intentionally has no implicit retry or reopen transition because doing so would restore authority while remote ownership remains unresolved. +Introduce `originweave-browser-session` as an independent Rust bounded context and retain ADR status `Proposed` until protected-main and real-browser acceptance exist. -`DisposableIsolationId` is addressability and lifecycle identity, not policy or presentation authority. Callers can validate an identifier value, but they cannot mint `PresentationMutationAuthority`; only the Browser Session aggregate can bind a port-created isolation boundary to a context epoch and issue the opaque authority token. +1. `BrowserSession` is the aggregate root. `BrowserSession::start` allocates a process-local, monotonically non-reused `BrowserSessionIncarnation` before browser I/O. Allocation fails closed before `u64` wrap. +2. Presentation authority is intentionally non-serializable. A process restart destroys every outstanding in-memory authority. Within one process, `BrowserSessionIncarnation` prevents sequential ABA when a later aggregate reuses the same external session, isolation, context, and local epoch values. +3. The same `BrowserSessionIncarnation` is passed through `DisposableContextPort` create and destroy calls. Adapters must scope their remote ownership mapping to that incarnation. Ignoring it violates the port contract. +4. A context enters the owned set only after `DisposableContextPort::create_disposable_context` returns a `DisposableContextHandle`. Raw `BrowsingContextId` input never creates ownership. +5. `PresentationMutationAuthority` is opaque and binds browser session, Browser Session incarnation, disposable isolation, browsing context, and context epoch. All fields must match current aggregate ownership before adapter I/O. +6. `DisposableContextCreateError::CreateFailedClean` is valid only when no remote boundary exists. `DisposableContextCreateError::CreateFailedUncertain(Option)` enters `RecoveryRequired`; when the browser-issued isolation/user-context identity is known, it is preserved exactly. +7. Duplicate browsing-context or isolation output enters `RecoveryRequired` and stores the complete offending `DisposableContextHandle` as recovery evidence. OriginWeave does not auto-destroy it because the adapter may have returned foreign state. +8. `BrowserSessionRecoveryEvidence` records only reconciliation evidence: `PartialCreationIsolation`, `DuplicateAdapterHandle`, and `UnprovenDestruction`. It grants no browser command authority. +9. Destruction validates exact authority before I/O, passes the current incarnation and stored handle to the port, and succeeds only after the adapter proves the exact boundary is gone. `DisposableContextDestroyError` moves the record and aggregate into recovery and retains the exact failed handle. +10. Transport liveness is stored separately from ownership state. The first `record_transport_loss()` records the fact even after `RecoveryRequired`; later duplicate reports are idempotent. If transport is lost while the aggregate is `Active`, the lifecycle state becomes `TransportLost` and active contexts become uncertain. If ownership was already uncertain, `RecoveryRequired` remains the lifecycle state and the transport-loss fact is retained alongside it. +11. `RecoveryRequired`, `TransportLost`, and `Ended` reject active-only creation, authority issuance/advance, destruction, and normal end. Reconciliation is a later, separately authorized design. +12. Context epochs remain monotonic authority identities within one aggregate. They invalidate older authority after navigation or another lifecycle boundary but are not a substitute for session incarnation. -The implementation deliberately does not convert `PresentationMutationAuthority` into the WebDriver BiDi crate's private presentation/screen-area witnesses. That bridge belongs to a later integration slice after both sides' contracts are reviewed. It also does not claim real-Chromium cleanup evidence. +## Alternatives considered -## Options considered +### Treat any known context as owned -### A. Treat any known browsing context as owned +Rejected. It restores the authority-confusion defect and allows one task to clear another task's state. -Rejected. It recreates the original authority-confusion defect and allows one task to erase another task's predecessor state. +### Depend only on browser-issued isolation identity -### B. Add only an aggregate-local incarnation or epoch +Rejected. The WebDriver BiDi user-context identifier is suitable lifecycle addressability, but this ADR does not assume a historical non-reuse guarantee after removal. A later aggregate therefore needs a separate OriginWeave lifecycle generation. -Rejected as insufficient. An incarnation field can prevent one aggregate from accepting another aggregate's token, but if adapter destruction is still addressed only by reused session/context identifiers, a valid token from aggregate B can still cause the adapter to destroy aggregate A's boundary. The non-aliasing identity therefore has to reach the port boundary itself. +### Add an aggregate-only random or monotonic nonce -### C. Treat every creation failure as clean +Rejected if it does not reach the lifecycle adapter. It would stop one aggregate from accepting another aggregate's token while still allowing a valid current token to address a remote boundary through aliasable adapter keys. The selected `BrowserSessionIncarnation` participates in both authority validation and port calls. -Rejected. A transport or adapter failure after `browser.createUserContext` may leave a remote boundary whose ownership was never recorded. Normal completion after such a failure would produce false cleanup evidence. +### Persist authority generations globally -### D. Treat every uncertain lifecycle failure as transport loss +Deferred and unnecessary for the current in-process authority model. Presentation authority is not durable across process restart; recovery across restart belongs to evidence/reconciliation design, not silent authority resurrection. -Rejected as semantically imprecise. Browser transport may still be healthy while ownership of one create or destroy attempt is unknown. A distinct `RecoveryRequired` state preserves the causal distinction while remaining fail closed. +### Treat every uncertain lifecycle failure as transport loss -### E. Keep the aggregate active after an unproven destroy +Rejected. Ownership uncertainty and transport liveness answer different operational questions. Collapsing them loses information needed for safe reconciliation. -Rejected. Marking only one record uncertain blocks normal `end()` but still allows new disposable contexts and unrelated authority to be created in an aggregate whose remote cleanup state is unresolved. That compounds uncertainty and weakens the ownership boundary. +### Automatically clean duplicate or partial state -### F. Snapshot every predecessor presentation override and restore it exactly +Rejected. When ownership is ambiguous, cleanup itself can become a cross-owner destructive action. Exact recovery evidence is retained while normal authority stays blocked. -Deferred. Exact predecessor capture can support reusable/attached contexts later, but today OriginWeave does not have a complete standard protocol snapshot for every governed presentation surface. Partial restoration would be a false safety claim. +### Snapshot and restore every predecessor presentation override -### G. Own a disposable isolation lifecycle and issue opaque authority only after proved creation +Deferred. OriginWeave does not yet have a complete queryable predecessor-state contract for every governed presentation surface. Disposable ownership remains the stronger first implementation. -Selected. The Browser Session records a port-proved non-aliasing isolation identity together with its browsing context and epoch. A WebDriver BiDi adapter should map that identity one-to-one to a fresh user context and remove that exact user context during cleanup. Proved-clean create failure may leave the aggregate active; uncertain create failure, duplicate adapter output, or unproven destruction requires recovery. Creation and destruction errors remain method-specific so the ACL cannot express a failure from the wrong lifecycle phase. +## Consequences -## Decision +The Browser Session aggregate now carries an explicit lifecycle generation through the anti-corruption boundary instead of treating protocol identifiers as durable capabilities. A retained token from aggregate A cannot validate against aggregate B solely because the browser or adapter later reused the same external identifiers and local epoch. -Introduce `originweave-browser-session` as an independent Rust bounded context with these invariants: - -1. `BrowserSession` is the aggregate root. It begins `Active` and may end normally only after every owned disposable context has proven destruction. -2. A context enters the aggregate's owned set only after `DisposableContextPort::create_disposable_context` succeeds with a `DisposableContextHandle`. Supplying a raw `BrowsingContextId` never creates ownership. -3. The handle contains both the browsing-context address and a `DisposableIsolationId` that the adapter contract requires to be non-aliasing for the live lifetime of the isolation boundary. A WebDriver BiDi adapter maps it one-to-one to the unique user-context id. -4. Successful owned-context creation mints a non-caller-constructible `PresentationMutationAuthority` bound to the exact browser session transport identity, disposable isolation identity, browsing context, and context epoch. -5. Two aggregates may reuse the same external `BrowserSessionId`, `BrowsingContextId`, and local epoch without sharing authority when their disposable isolation identities differ. Foreign isolation authority is rejected before adapter I/O. -6. `DisposableContextCreateError::CreateFailedClean` means no remote boundary exists and leaves the aggregate active. `DisposableContextCreateError::CreateFailedUncertain`, duplicate browsing-context output, or duplicate isolation output moves the aggregate to `RecoveryRequired` and invalidates active authority. Destruction-only failures cannot appear on this method boundary. -7. Advancing the context epoch invalidates previously issued authority. Adapter integration must use this transition at navigation/renderer lifecycle boundaries that invalidate the prior authority scope. -8. Destruction requires exact current authority and passes the stored `DisposableContextHandle` back to the port. The aggregate retains that already-validated mutable record across the port call; it does not perform a second impossible lookup after I/O. The method returns only `DisposableContextDestroyError`, so creation-only outcomes cannot cross into cleanup semantics. -9. If destruction cannot be proved, the failed record becomes `Uncertain`, the Browser Session moves to `RecoveryRequired`, every remaining active record becomes uncertain, and further creation, authority lookup/advance, destruction, and normal end are rejected until an explicit reconciliation design exists. -10. Transport loss moves the Browser Session to `TransportLost`, marks still-active owned contexts uncertain, and prevents further authority issuance. -11. `RecoveryRequired`, `TransportLost`, and `Ended` reject all transitions that require an active session. Reconciliation is a later explicit design; none of these states silently reopens ownership. -12. Epoch sequence numbers are monotonic authority identities, not business counters; gaps are allowed after failed creation or rejected duplicate adapter output. +Recovery is also diagnosable rather than merely terminal. Known partial user-context identities, duplicate returned handles, and exact handles whose destruction could not be proven remain available as `BrowserSessionRecoveryEvidence`. This evidence is purpose-bound to later reconciliation; it is not a cleanup credential. -## Consequences +Transport failure can now be observed after ownership has already become uncertain without replacing or erasing that uncertainty. This supports later recovery planning that distinguishes “ownership uncertain but transport still live” from “ownership uncertain and transport lost.” -Browser Session ownership becomes a domain fact carried through the adapter lifecycle instead of a convention reconstructed from transport identifiers. Proved-clean and uncertain outcomes are no longer conflated, so normal completion or continued mutation cannot hide a potentially leaked browser boundary. Once cleanup becomes uncertain, the aggregate stops issuing new authority rather than accumulating more browser state beside an unresolved boundary. +The selected process-local incarnation has a deliberate scope. It prevents ABA only for outstanding in-memory authority within the running process. Durable restart reconciliation must use separately persisted evidence and browser observation; this ADR does not serialize or resurrect authority across restart. -Method-specific port errors also remove a class of defensive branches that had no valid domain meaning. An adapter cannot report destruction failure from creation or creation failure from destruction, so the aggregate no longer has to interpret an impossible phase transition as a degraded case. +## Security and governance impact -The Browser Session domain relies on an explicit adapter proof obligation for global live-lifetime non-aliasing of `DisposableIsolationId`. For WebDriver BiDi that proof is the standard's unique user-context identifier plus adapter conformance tests that preserve the mapping and remove the exact user context. A generic random adapter token without a verified one-to-one browser lifecycle mapping is not sufficient. +No page-controlled value, raw browser-session id, raw browsing-context id, user-context string, provider/model decision, or LLM output can mint presentation authority. The adapter receives domain-issued incarnation information only as a lifecycle-scoping input and cannot manufacture Browser Session policy authority. -The slice remains incomplete for buyer acceptance. No real Chromium user-context adapter, presentation-witness bridge, observed cleanup receipt, crash/recovery reconciliation, or #299 full browser replay is claimed here. +Unknown or duplicate remote state is quarantined rather than destroyed speculatively. This reduces the risk that recovery logic removes another owner's user context. It does not replace Chromium sandboxing, egress policy, Keyverse secret handling, Wardnet controls, or central workflow security. -## Failure and degraded behavior +## Tests and exact evidence -`DisposableContextCreateError::CreateFailedClean` produces no authority and permits continued active operation because the adapter has proved that no disposable boundary exists. `DisposableContextCreateError::CreateFailedUncertain`, duplicate adapter output, and any `DisposableContextDestroyError` move the Browser Session to `RecoveryRequired`; existing active records become uncertain and all active-only transitions are blocked. Duplicate output is never automatically destroyed because a contract-violating adapter may have returned another owner's state. A failed destroy preserves the exact failed handle as uncertain evidence; it is not retried implicitly and no later adapter I/O is admitted from that aggregate. Transport loss uses the separate `TransportLost` state. Once a Browser Session is `Ended`, `TransportLost`, or `RecoveryRequired`, creation, authority lookup, destruction, epoch advancement, and normal end transitions that require an active session fail closed. +The test suite covers raw-context rejection, bounded isolation identity parsing, typed clean/uncertain creation, retained partial identity, duplicate-handle evidence, epoch exhaustion, stale epoch rejection, foreign-session/isolation rejection, destruction failure, transport loss, normal end, and incarnation-allocation exhaustion. -## Security / privacy / governance impact +A dedicated hostile test, `stale_authority_cannot_cross_sequential_session_incarnations`, creates aggregate A, destroys and ends it, creates aggregate B with the same external session/user-context/browsing-context values and local epoch, and requires A's retained authority to fail before B adapter I/O while B's current authority succeeds. The port records incarnation values so the test also proves that the lifecycle mapping receives the new generation. -Disposable context ownership reduces cross-task presentation-state interference and is compatible with isolated Agent Task profiles. Typed lifecycle outcomes prevent a failed browser command from being misreported as a clean lifecycle or followed by fresh authority while cleanup is unresolved. Method-specific failure types also prevent invalid lifecycle-phase semantics from crossing the Browser Session anti-corruption boundary. This is not a substitute for Chromium sandboxing, egress policy, origin capability policy, Keyverse secret handling, or evidence retention controls. Those remain with their canonical owners. +`destroy_failure_requires_recovery_before_any_new_authority` requires an unproven destruction to retain the exact failed handle, enter `RecoveryRequired`, then record a later real transport loss without erasing ownership evidence; repeated loss reports are idempotent. -No page-controlled value, secret, provider/model choice, LLM result, raw browser-session id, or raw browsing-context id can mint Browser Session presentation authority. +The RED for the sequential ABA defect was captured on exact `ec145963ad8fe19c9416f2b3856b94660082dbf7` in CI `34469580144`: repository contracts and formatting passed, and Rust `Run tests` failed at the new hostile test before Clippy/rustdoc. The production fix and subsequent documentation/test updates must earn a new exact-head GREEN; predecessor evidence does not transfer. -## Tests and acceptance evidence +Repository contracts, canonical formatting, locked Rust tests, strict Clippy, rustdoc/API docs, exact function/line/region/branch coverage, independent review, and applicable central checks remain required before ordinary adoption into #313. -The owning crate tests hostile raw-context lookup, bounded isolation identity parsing and handle accessors, proved-clean versus uncertain creation failure, duplicate adapter output, epoch exhaustion, stale authority, cross-session authority, foreign isolation authority, cleanup failure, transport loss, unknown context, epoch advancement, successful destroy-before-end behavior, and a two-aggregate alias case. Duplicate and uncertain-create branches assert `RecoveryRequired`; the dedicated `destroy_failure_requires_recovery_before_any_new_authority` hostile test requires an unproven destroy to quarantine the whole aggregate and rejects later creation/authority/epoch/end before adapter I/O. +## Buyer acceptance still open -Repository contracts require the bounded context to be a workspace member, keep ADR 0114 indexed, preserve the non-aliasing port contract, retain `RecoveryRequired`, and require distinct `DisposableContextCreateError` and `DisposableContextDestroyError` types. Exact-head CI, Clippy, rustdoc, function/line/region/branch coverage and independent review remain required before integration. Real-browser acceptance is deferred to a later adapter slice and must prove unique user-context creation, page-observed mutation, exact-boundary cleanup/destruction and post-cleanup isolation in pinned Chromium; command ACK alone is not success. +This slice does not yet prove real WebDriver BiDi `browser.createUserContext`/`browsingContext.create`/`browser.removeUserContext` integration, browser-observed destruction, recovery reconciliation, Browser Session→BiDi private-witness conversion, pinned Chromium presentation post-conditions, crash/restart cleanup, #299 3/3 Agent Task replay, or protected-main release/SBOM/provenance/reproducibility/rollback. ## Migration and rollback -This is additive.

This prevents a partial create from being followed by a false normal `end()`. +`BrowserSessionIncarnation` is process-local and monotonic. Presentation authority is not persisted across process restart, so restart invalidates outstanding authority rather than requiring a durable counter. Within one running process, the incarnation is checked by the aggregate and passed through the lifecycle port; an adapter that ignores it does not satisfy the ACL contract. -Destruction has a separate `DisposableContextDestroyError`; creation-only failures cannot be returned from the destroy boundary, and destruction-only failures cannot be returned from create. If exact disposable-boundary destruction cannot be proved, the failed record becomes `Uncertain`, the whole Browser Session enters `RecoveryRequired`, every remaining active record becomes uncertain, and later context creation, authority issuance/advance, destruction, and normal end are rejected before adapter I/O. A raw `BrowsingContextId`, stale epoch, foreign session, foreign isolation, unknown context, lost transport, or recovery-required session likewise cannot enter the successful chain. +## Lossless recovery evidence + +`DisposableContextCreateError::CreateFailedClean` is valid only when no disposable browser state exists. `CreateFailedUncertain(Some(isolation))` retains the exact known user-context/isolation identity as `BrowserSessionRecoveryEvidence::PartialCreationIsolation`; `None` remains representable when no identity was obtained. Both uncertain cases enter `RecoveryRequired` and mint no authority. + +Duplicate browsing-context or isolation output stores the complete offending `DisposableContextHandle` as `DuplicateAdapterHandle` before recovery quarantine. OriginWeave deliberately does not auto-destroy duplicate output because ownership may be foreign. Failed or unproven destruction records `UnprovenDestruction` with the exact owned handle. Recovery evidence authorizes no browser command; it exists only for a later reviewed reconciliation path. + +## Orthogonal transport liveness + +Transport liveness is tracked independently from ownership recovery. If transport loss occurs after `RecoveryRequired`, the aggregate keeps `RecoveryRequired`, preserves all recovery evidence, and separately records `transport_lost = true`. The first loss report is observable; repeated reports are idempotent. If loss occurs while `Active`, the lifecycle state becomes `TransportLost` and active context records become uncertain. + +This avoids conflating “ownership uncertain while transport may still be usable for separately authorized reconciliation” with “ownership uncertain and the transport is gone.” + +## Sequential ABA safety + +The sequential ABA hostile case is explicit: aggregate A creates `(S,U,C,epoch=1)`, proves destruction, and ends. Aggregate B later starts with the same external `S`; the adapter may return the same `U/C`, and B also begins at local epoch 1. A's retained authority must still fail before any B adapter I/O. B receives a different `BrowserSessionIncarnation`, and only B's newly minted authority is accepted. + +The port also receives the incarnation on create/destroy. This closes the prior gap where an aggregate-only nonce could protect token comparison while the browser adapter still keyed destruction by aliasable raw identifiers. ## Standards trace -The design dossier references the 9 September 2026 WebDriver BiDi Working Draft.
