Secrets were clipped before they were masked, so a long JWT left its readable start behind in route params, NgRx strings and form values. Several egress paths never ran the shared redaction at all: form events, unlinked WebMCP tools, the NgRx page url and title, the HTTP page title, hydration warnings and parse errors, httpResource urls, link hrefs and the Analog page url. Collectors also marked failed pushes as sent, skipped calls that finished during a push, and the Analog and Injectors panels did not scope to their own tab. Fix each in the shared helper or at its single choke point, and cover it with a regression test.

Review comments at @app/src/pages/di-inspector.ts:
- Line 1564: Update loadInjectorTree to track a monotonically increasing
generation for each load, and reject a completed load before it applies state or
installs a listener if its generation is no longer current. Keep the existing
destroyed-component and RPC-client checks.
Review comments at @packages/devtools/src/forms-dom.ts:
- Line 85: Update the ancestor selection in the code around `controlCount` so it
starts with no selected container and selects only an ancestor that passes the
control-count check; ensure a shared `fieldset` containing multiple controls is
not selected, including when the inputs are its direct children.
Review comments at @packages/devtools/src/rpc/get-providers.ts:
- Line 353: Update the forwardRef matcher in the provider parsing logic to
accept only a complete callback result that is a token reference, not a function
call such as Foo(). Add a near-miss test verifying computed callback results are
not reported as injected tokens.

…matching Address review findings. An older injector-tree load for the same client could resolve last and replace the newer state and listener, so each load now carries a generation. A field whose parent fieldset holds several controls no longer borrows that fieldset as its error container. inject(forwardRef(() => Foo())) is no longer reported as token Foo.

What was wrong
An audit of the inspectors found secrets leaving the page through paths that skip the shared redaction, secrets that survive because they were clipped before they were masked, collectors that mark a failed push as sent, and two panel pages that did not stay on their own tab. This pull request fixes 35 distinct bugs (49 audit entries; several auditors reported the same bug). Each fix is in the shared helper or at the one place the data leaves, not at every call site.
Root causes and fixes
Masking after clipping
forms.tsserializeFormValue, used byredactRecord): strings were cut to 200 characters before the JWT and bearer patterns ran, so a long JWT left its header and payload behind. Strings are now masked first, then cut.ngrx-shared.tsserialize): same order problem withmaxString. Masked first, then cut.serialize.ts): keys were copied raw while Map keys were masked. Keys are masked now, and two keys that collapse to the same text stay as two entries.__proto__key (serialize.ts): assignment set the prototype and dropped the data. Keys are defined as data properties.forms-privacy.tsredactMessage): a short secret that prefixes a longer one left the tail of the longer one. Secrets are masked longest first.Paths that never ran the shared redaction
forms-collector.ts):valueevents and theirprevbaseline carried JWTs, bearer tokens and secrets learned from other fields.recordFormEventand the baseline seed now go throughredactFormText.forms-webmcp.ts): description, error and call detail were sent as is. They fall back toredactMessage.ngrx-overlay.ts,rpc/ngrx-tools.ts): redacted on the page and again inmergeNgrxReport, so adescribe()override cannot bypass it.devframe.ts,http-payload.ts,http-overlay.ts,http.ts,http-hydration.ts): masked on the page before the 1000 and 500 character cuts, and again on the server.httpResourcerequest url (signal-resources.ts): now goes throughredactUrl.analog-server-log.ts): query redaction ignoredredaction.secretNamesandsig,signatureandauth; it swallowed the closing quote and later keys of JSON strings; andkey=valuepairs with quoted values or inside JSON strings were missed. The query value now stops at quotes and whitespace, honoursisRedactedKey, and pair masking handles quotes and JSON string values.http-redact.ts): a secret nested in an object or array, or an array value, was skipped by the pair regex. The preview now uses the bracket-aware scanner that Analog already had, moved tojson-text-redact.tsand shared by both.analog-runtime.ts), the navigation adopted at connect time (router.ts), and RouterLink hrefs (router-links.ts) now pass the config secrets, so/reset/:tokenis masked before any navigation event.Collectors that lose or mis-send data
http-overlay.ts): the cursor was taken after the await, so those calls were never sent. It is taken before.overlay.ts): the component tree, injector tree and router push kept the new payload as "sent" when the RPC failed, so keepalive pings kept stale data alive. They reset on failure, as the signal graph does.overlay.ts,http-overlay.ts): panel-triggered forced pushes and thehttp-clearhandler had no catch.forgetHttpPages(devframe.ts):some()stopped deleting payloads after the first match.Forms DOM facts
[ngValue](0: foo) was reported as view-out-of-sync drift.checkVisibility()ran withoutvisibilityProperty, sovisibility:hiddenerrors counted as shown.Source scan
.page.analogand.page.agpages were never scanned and their.server.tswas flagged as an orphan (rpc/analog-scan.ts).inject(forwardRef(() => Foo)),inject(Tokens.X)andinject(this.x)were reported underforwardRef,Tokensandthis; a constructor@Inject('STRING')was reported under the parameter type (rpc/get-providers.ts).Panel
hostPageId()(analog-inspector.ts).analog-projectcall left "Reading the project…" forever; it now shows an alert with Retry, and refresh retries while the project is missing.pageId(request-page-highlightaccepts{ pageId, selector }indevframe.ts, which the overlay already understood).extension/uiis rebuilt. The security page and the Analog inspector page describe the changed behaviour.How each is covered
Every fix has a regression test that was seen failing against the previous code (I reverted the non-test sources and re-ran: 35 package tests and 5 panel tests went red, then green again).
redaction-leaks.test.ts(new): clip-before-redact for NgRx and router records, longest-first secrets, object keys,__proto__, clipped JSON previews.overlay-push-failures.test.ts(new): tree, injector and router re-push after a failed push; no unhandled rejection from a forced push.forms-collector.test.ts,forms-webmcp.test.ts,forms-read.test.ts: form events, unlinked WebMCP tools, select drift,checkVisibility, shared fieldset.http.test.ts,http-server.test.ts: in-flight calls,http-clear, title and hydration masking on the page and on the server.ngrx-mcp.test.ts,signal-resources.test.ts,analog-runtime.test.ts,router-audit.test.ts(real Router for the link href),analog-server-log.test.ts,analog-scan.test.ts,get-providers.test.ts,panel-highlight-sessions.test.ts.analog-inspector-pages.test.ts(new),di-inspector-pages.test.ts.forgetHttpPagesis fixed without a test:httpPayloadsis only written and never read, so the leak cannot be observed through a public seam.Verified
pnpm test:devtools(1292 passed),pnpm test:panel(133 passed),pnpm typecheck,pnpm format:check,pnpm skills:check,pnpm commit:check,pnpm docs:build,pnpm test:axe(all views, light and dark) andpnpm extension:build(no diff after rebasing on main).Not fixed
forms.ts,forms-actions.ts): paths are joined and split on., so a control keyeduser.namecannot be told fromuser > name. Escaping the dot changes the path syntax that the panel and agents see, in about ten places; that needs a decision on the path format first.agent.tools.<inspector>: falsestill exposes data throughdevframe_state_readanddevframe://state:@devframes/hubpassesexposeSharedState: trueand takes no filter, and the panel needs the shared states. This needs a change in devframe (anexposeSharedStateoption on the hub) or a decision to split agent-visible state from panel state.Summary by CodeRabbit
