* fix(browser): name web-bundle budgets and recover web deadlines
Name the existing heap, per-script, and total web-bundle phases, and reject a per-script deadline above the total. Promote capture, CDP command, source-map decode, and source-map fetch deadlines at today's defaults. Name DevTools timeoutMs, and state that discovery, cleanup grace, byte budgets, and Electron hook retention have no runtime override.

* fix(browser): apply selected web deadlines to the owning phase
Keep HTTP and browser-socket discovery on the fixed discovery deadline so a
short command_timeout_ms starts at the handshake. Apply scenario
command_timeout_ms to launch startup and the primary connect session, and
keep service-worker restoration on the fixed 5000 ms grace. Omit
command_timeout_ms from recovery text when the operation does not accept it.

* fix(browser): retain scenario commands that finish after their deadline
A timed-out scenario command stays owned so cleanup can close a late
browser or context and restore a mutation that lands after the deadline.
Child storage replies use that deadline, scenario recovery names
command_timeout_ms in the capture JSON, and the session test connection
implements beginCleanupGrace.

* fix(browser): keep child command timeouts as the public failure
A nested command such as Page.enable that is delivered but never answered
was stored as protocol_error, hiding the command name, selected deadline,
and recovery. Store the typed timeout and assert that public error.

* fix(browser): keep runtime cleanup on the fixed grace
Switch runtime restoration to the cleanup grace before the first send so a
short command_timeout_ms cannot fail an otherwise successful observation.
Stop advertising command_timeout_ms on list_browser_targets, which never
bounds a post-discovery command.

* test(browser): prove a short command deadline cannot fail runtime cleanup
Drive restoration through the runtime fixture. A cleanup command that
outlives command_timeout_ms still succeeds, and a stalled restoration
names the fixed 5000 ms grace.

* fix(browser): name the effective source-map decode deadline
codecBudgetLimitation reported a fixed 20-second deadline after a
caller selected decode_timeout_ms. Result and Evidence limitations
now name that effective millisecond deadline.

* fix(browser): separate handshake and target-attach deadlines
A browser-level Target.attachToTarget no longer shares the WebSocket
handshake budget. Blocked service-worker attachment keeps discovery on
its fixed deadline and applies command_timeout_ms to the later handshake
and attach.

* fix(browser): name the web-bundle resource each runtime exhausts
Bun ignores the V8 old-space flag. A Windows Job reports the process
commit limit, and other Bun hosts no longer suggest raising max_heap_mb.

* fix(browser): cite the browser-socket discovery message budget
WebSocket discovery enforces the 64 MiB protocol budget. Timeout
recovery no longer advertises the 8 MiB HTTP document budget.

* fix(browser): bound the blocked service-worker check before discovery
The first registration check has its own fixed 10s deadline. Discovery,
handshake, and Target.attachToTarget stay on their separate deadlines.

* fix(browser): name the operand that stopped web-bundle admission
Host heap pressure no longer claims the fixed result budget is exhausted.
A Windows Bun allocation before the commit limit still names that limit.

Sample the browser monotonic clock with observation already subscribed, filter historical lifecycle and network facts, and preserve scope and termination handling when event time is unknown.
Bound pre-arm retention using transport-owned wire bytes. Fail closed when the relevant-event buffer fills, and keep unrelated protocol payloads outside that budget.
BREAKING CHANGE: observe_web_session timeline timestamps can be null when the producer supplies no comparable timestamp. Consumers must handle unknown time explicitly.
Refs #5609
Own CDP transports from admission through observed close, retain failed
owners for retry, and keep active peers separate from pending cleanup.
Preserve primary errors and completed facts through final cancellation.
Forward passive Electron CLI cancellation and dispose browser, runtime and
scenario owners from CLI and MCP shutdown.

* fix(build): emit no runtime imports for type-only bindings
Under verbatimModuleSyntax, an import whose specifiers all carry inline
`type` modifiers compiles to `import {} from "..."`, a side-effect import
that still resolves and evaluates the module. 78 compiled modules carried
one, including `import {} from "playwright-core"` in the browser scenario
session, which loaded Playwright's module graph at MCP startup.
Use top-level `import type` for these bindings and enable oxlint's
typescript/no-import-type-side-effects rule so the pattern cannot return.

* perf(mcp): load Playwright when a scenario launches, not at startup
The browser scenario and Electron active providers are constructed before
the stdio server serves, and both bound Playwright's launchers at module
load. Resolve `chromium` and `_electron` from playwright-core when a
capture opens instead, as the web module resolver already does.
MCP startup now resolves 1,312 modules (4,902 resolutions) instead of
1,598 (6,076) before reading the first request, and no longer loads
playwright-core. Provider construction, the tool catalog, and capability
inventory are unchanged.
A boundary test spawns the stdio server, initializes, lists tools, and
asserts playwright-core and isomorphic-git were not resolved; the CLI
probe now exercises the real launch path to prove detection.

Apply the 64 MiB protocol message limit when connect callers omit an override. Reject invalid explicit limits, including values that wrap through ws signed 32-bit coercion and disable enforcement. Preserve the typed payload_limit reason through disconnect and later commands.
Validation: 16 transport boundary tests passed, including UTF-8 exact/+1 limits and an oversized frame header without allocating its body. Real Chrome 154 CLI/MCP browser verification and check:fast passed. This caps message bytes, not decoded JSON heap size.
Move each error family out of domain/errors.ts into its own module
(base, core, provider selection/adapter, browser observation,
artifact, evidence, unknown registry, hopper, configuration) and
relocate AnalysisErrorProjection to analysisErrorProjection.
Migrate all 162 importers to the owning modules and delete
errors.ts. No re-export shims; behavior is unchanged.
* refactor(domain): consolidate canonical ordering and digest helpers (#624)
* refactor(domain): consolidate canonical ordering and digest helpers
Single owner for code-point ordering (domain/canonicalOrdering.ts)
and canonical JSON digests (domain/comparisonSemantics.ts). Delete
all local compareCodePoints/compareText/digestCanonical duplicates
and migrate every importer. No re-export shims.
* fix(ci): allow slower real browser startup
* chore(config): remove dead eslint, dedupe scripts, cacheable turbo tasks
Delete eslint.config.js (oxlint is the linter), drop lint:dead alias,
pin smol-toml, fold jscpd/scan:todos into check:pr, make test:run
cacheable, align oxlint ignores.
* fix(config): hash all test inputs for cached runs
* docs: fix architecture diagram and pretty-print tool catalog
Drop dangling REPLAY edges, add dotnet/reference/error/evaluation
nodes. Emit 2-space JSON from the catalog generator and regenerate.
* test: extract shared fixtures, drop knip carve-outs
Dedupe android/apple session tests, bundler adapter headers, and
reconstruction helpers into tests/support fixtures. Delete unused
type aliases and the knip ignoreIssues block. Lower jscpd threshold
2.7 to 2.5.
* refactor(app): split Setup and ProcessOwnership modules
Extract SetupTypes/SetupHost from Setup.ts and move observation
helpers into ProcessOwnershipObservation/ProcessTree. Migrate all
importers including CLI commands. No re-export shims.
* refactor(runtime): centralize safe JSON parsing and preserve error causes
Add domain/safeJson.safeParseJson and migrate all raw JSON.parse
call sites. Name catch causes and preserve failure reasons instead
of swallowing; annotate genuine best-effort cleanup.
* fix(runtime): retain JSON parse error causes
