* fix(stalker): only mint a temporary link when the row asks for one `create_link` ran on every Stalker playback. The reference client — the portal's own `player.js`, mirrored by Kodi's pvr.stalker — mints a link only when the catalog row sets `use_http_tmp_link` or `use_load_balancing`; otherwise it plays the static `cmd` that `get_all_channels` / `get_ordered_list` already returned. Neither flag was read anywhere in the codebase, so every channel paid a round trip and gained a failure point the reference client does not have. One helper now owns the decision (`resolveStalkerStaticPlaybackUrl`), used by `fetchStalkerPlaybackLink()` for ITV/VOD/radio, by the download path, and by `StreamResolverService` for Favorites/Recently Viewed. Its guards are deliberately wider than the flags alone and can only route a row back onto the `create_link` path: no row to read flags from, a relative or query-only command (the VOD `has_files` rewrite), a non-HTTP scheme, or a loopback host. An episode always mints, since `series` selects it server-side. Radio joins the same decision, so a station the portal proxies now gets its link instead of playing a URL the portal never meant to serve. Temporary links live ~5 s, so the audit that came with this: favorites and recently-viewed persist the `cmd`, playback positions store ids, and the main-process context map stores headers keyed by origin+path — none replay a resolved URL. Downloads are the documented exception, and honouring the flags shrinks even that, since an unflagged movie now yields a permanent URL that survives retry. `forced_storage` and `play_token` stay unwired, with the reasoning recorded in the docs rather than left ambiguous. The mock's ITV/radio rows now carry both flags, and the new `static-channel-cmd` scenario (MAC 00:1A:79:00:00:0A) serves unflagged rows with a playable command so the e2e can assert that NO `create_link` request reaches the portal — verified to fail when the change is reverted, with a companion test proving the recorder sees a link when one is due. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): keep temporary-link flags across VOD normalization Codex P1 on #1364, and it is real. `buildStalkerSelectedVodItem()` narrows a raw portal row to an explicit whitelist, and the two flags were not on it. It feeds both `selectedItem()` — which the VOD playback path reads as `linkFlags` — and, through `createStalkerVodItem`, the download payload. So a flagged VOD row with an absolute HTTP `cmd` arrived looking unflagged and took the static path, playing the portal's non-final URL instead of minting a link. The direction of the failure is what makes it a P1: a dropped flag reads as "no temporary link needed", so the whitelist fails OPEN. Both flags now sit on `StalkerVodSource` / `StalkerSelectedVodItem` and on the whitelist, with the consequence spelled out at the normalizer so the next edit does not quietly undo it, and specs pinning all three normalizers plus a store-level test that a flagged VOD still mints. Also two things from re-reading my own diff: - The radio path called `resolveStalkerStaticPlaybackUrl` and then handed the same row to `fetchStalkerPlaybackLink`, which runs that exact check again. Two copies of one decision is the divergence this PR exists to remove, so the outer call and its now-unreachable guard are gone. - `portal-catalog-facade.ts` spells the flag shape out instead of importing `StalkerLinkFlagSource`; it now says why (`type:util`/`domain:portal-shared` may not depend on `type:data-access`/`domain:stalker`), so the obvious "reuse the type" cleanup does not get made and break the boundary lint. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): authenticate before serving a static collection stream Second Codex P1 on #1364, and a regression this PR introduced. `create_link` was also the request that warmed the portal session. Tokens live in memory only (`StalkerSessionService.tokenCache` is a plain Map), and the collection header builder reads the raw `getCachedToken()`. So a cold start from global Favorites or Recently Viewed — the portal never opened this session — took the static path, found no token, and handed a same-host gated stream headers with no `Authorization`: a 403 on exactly the streams the header contract exists for. The same raw accessor cannot tell a token negotiated for a pre-edit identity from a current one. `StreamResolverService` now calls `ensureToken()` before building a static playback. It is the right primitive: handshake + `get_profile` with no link minted, identity fingerprint validated, concurrent callers deduped, and an immediate null for simple portals — and calling it keeps this change out of `stalker-session.service.ts`, which PR 6 (#1354) is splitting. Best-effort by design: a static URL may point at a CDN that needs no credentials, so a failed handshake degrades to the token-less header set instead of costing the user their playback. Both halves are pinned by tests, and removing the call makes the cold-start test fail. The portal routes need no equivalent and do not get one: an item cannot be selected before its catalog has loaded, and every catalog load authenticates. That reasoning is now written down rather than assumed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): warm the session at the choke point; keep downloads authenticated Two more Codex findings on #1364, and the first one shows my previous commit message reasoned too broadly. P1 — I claimed the portal routes are "structurally warm" because an item cannot be selected before its catalog loads. That is true of the routed portal views, but not of the global collection detail, which calls `setCurrentPlaylist()` and `setSelectedItem()` straight from a persisted row with no catalog load in between and then goes through the STORE playback path. A VOD opened from Favorites on a cold start therefore still played a same-host gated stream with no Bearer token. Rather than extend the per-route argument, the warm-up moved to the one place every static return passes through: `fetchStalkerPlaybackLink()` now calls the session before short-circuiting, covering ITV, VOD, radio and downloads at once. `StreamResolverService` keeps its own call — its static branch does not go through that function — but both now share a single primitive, `ensureStalkerSession()` in `stalker-request.utils.ts`, so the two routes cannot drift on when a session is required. Still best-effort, still outside `stalker-session.service.ts` (PR 6 territory). P2 — downloads cannot use that escape hatch at all: the main-process stored header allowlist is User-Agent/Origin/Referer only, no Cookie or Authorization, so a static same-host URL 401s where a minted one worked. `startStalkerVodDownload` now classifies the candidate with the shared `isStalkerStreamCredentialSafe()` and withholds the row — forcing `create_link` — for anything portal-owned. A CDN-hosted movie keeps the permanent URL that survives retry; a portal-hosted one keeps the minted URL that carries its own token. Both fixes mutation-checked: each reverted change fails exactly one test. Docs corrected, including the overreaching "structurally warm" claim. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(stalker): record the cached-token revalidation trade-off Codex flagged that the static path no longer self-heals a retired token, since `ensureToken` returns a same-identity cache entry without a network call — whereas `create_link` used to refresh it through `makeAuthenticatedRequest`'s auth-failure retry. The mechanism it posits does not exist on stock Stalker: per the 4.9.35 reference, handshake tokens have no TTL, and not sending the watchdog does not invalidate auth (it only clears the admin panel's "online" flag). The real residual vector is another device calling `get_profile` on the same MAC, which is common enough on shared subscriptions to be worth naming. Revalidating on every static playback would cost exactly the round trip this change removes, so it is deliberately not done. Recorded as a known trade-off with its mitigation (a running watchdog still self-heals within a ping cycle) and handed to PR 6, where a refresh on an OBSERVED playback authorization failure belongs. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(stalker): tighten the token-revalidation trade-off wording Greptile review feedback: the watchdog mitigation was the most important part of that paragraph and sat behind the caveat. It now follows the MAC-sharing vector directly, and the paragraph ends by naming what is actually left uncovered — a same-host static stream played while no watchdog is up — so a future reader can size the residual without re-deriving it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): prefer the live playlist row over a stale favorite snapshot Codex P1 on #1364, and mine. `resolveStalker` reads its portal coordinates as `item.stalkerPortalUrl ?? playlist?.portalUrl` — item first. The create_link branch quietly corrected for that afterwards by re-reading `applyOverride(playlist).portalUrl`, so the row won wherever it existed, which is what the comment right above it already promised: "when the row exists it wins over the item's snapshot of the portal URL (a repaired endpoint must beat a stale favorite)". The static branch I added returns before that correction, so it shipped the stale snapshot. Consequences after a playlist edit: a same-host static URL matching the OLD host gets the newly negotiated token and identity headers sent to the previous portal, and a MAC-only edit pairs the new token with the old MAC cookie — precisely the pairing `stalkerIdentityFingerprint` exists to prevent. Both branches now derive the coordinates once, row-first with the repair override applied, and fall back to the item's snapshot only for a playlist that no longer exists — which is the role `buildStalkerPlayback` already documents for it. Mutation-checked: restoring item-first precedence fails the new test alone. Also documents a local-only e2e hazard found while re-running the suite: `mode: 'serial'` orders tests within one project, but chromium/firefox/webkit run the file concurrently against the same mock server, so one project's beforeEach reset can drop a session another is mid-test on — which is what a lone auth-spec failure that passes on rerun actually is. CI never sees it; the Web E2E job runs --project=chromium alone, and that command is clean (22/22). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): warm the session against the repaired portal configuration Found while auditing my own static branch against the create_link path rather than waiting for the next review round. `executeStalkerRequest` applies the lazy-repair override on its first line, so the create_link path always talks to the configuration a completed repair proved good. The session warm-up I added did not: it handed `ensureToken` the caller's pre-repair row, so a portal whose endpoint or mode had been repaired would handshake against the configuration the repair had already rejected — stranding the session precisely on the portals repair exists to rescue. The override now happens inside `ensureStalkerSession`, mirroring `executeStalkerRequest`'s first line, so every caller inherits the rule instead of each having to remember it. Mutation-checked: dropping the override fails the new test alone. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): fall back to create_link when a portal-owned static url has no session Codex P1 on #1364. `create_link` was also the request that could FAIL, and a failure is what triggers the lazy portal repair. A playlist still misclassified as token-free, or pointing at an unrepaired endpoint, used to self-heal on that failure and then play; the static path issues no request, so nothing fires and the stream just 401s. Its suggested remedy — routing a skipped warm-up through `repairPortal()` — cannot be taken literally: a skipped warm-up is the NORMAL case for the many legitimately token-free reseller panels, and probing each of them on every playback would cost far more than the round trip this PR removes. What is decidable without a request is whether we are about to serve a stream we already know will fail. `ensureStalkerSession` now reports whether the session can serve credentialed playback — true for a portal needing no token and for one holding a usable token, false for a full portal left without one — and both static call sites act on it: - foreign-host URL: served regardless, it never needed the session; - portal-owned URL with a usable session: served, as before; - portal-owned URL with no usable session: falls back to `create_link`, which mints a URL carrying its own token AND re-enters the only path that can observe a failure and repair. That covers the unrepaired-endpoint half exactly. The misclassified-as-simple half stays open by construction — no request means no evidence, and "simple portal" is indistinguishable from "misclassified" without one. It belongs with the other reactive-repair work already handed to PR 6: refresh and repair on an OBSERVED playback authorization failure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): require flag evidence before trusting a row as unflagged Two Codex findings on #1364. P1 — legacy persisted snapshots. Favorites and Recently Viewed rows saved before this change went through `buildStalkerSelectedVodItem`'s whitelist, which dropped both flags, and `buildStalkerFavoritePayload` spreads that whitelisted object. So a legacy row is flagless because WE stripped it, not because the portal said no — and the helper was reading it as "explicitly unflagged". With an absolute HTTP `cmd` from a load-balanced portal that meant playing a non-final URL. There is no migration or provenance marker for those rows. A stock portal returns both flags on every row, so their PRESENCE is itself the provenance signal, and it is the only one available without a refetch. `resolveStalkerStaticPlaybackUrl` now requires at least one flag key to be present; absence reads as "no evidence" and routes back to `create_link`, which is the pre-PR behaviour. This costs the optimization on panels that omit the flags entirely — the honest price for not being able to tell them apart from our own stripped rows. Radio is the one documented exception. It has always played a directly usable command without `create_link`, so a flagless radio row keeps that rather than newly minting — a portal whose radio `create_link` never worked would otherwise lose playback it has today. ITV and VOD have no such history and stay conservative. P2 — loopback range. IPv4 reserves all of `127.0.0.0/8`, so `127.0.0.2` was being handed to the player as a real address. Classified by range now, with a test that `127.0.0.1.cdn.example` is still treated as the ordinary hostname it is. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): classify every portal-local IPv6 placeholder Codex P2 on #1364, same class as the 127.0.0.0/8 one. `http://[::]/ch/1234_` and the IPv4-mapped loopback forms slipped past the exact-name set and would have been handed to the player as real addresses. Checked how `URL` actually normalizes these rather than guessing at the spelling a portal might use: brackets are kept, `[0:0:0:0:0:0:0:1]` collapses to `[::1]`, and an IPv4-mapped address is rewritten to hex — `[::ffff:127.0.0.1]` arrives as `[::ffff:7f00:1]`. The guard now strips the brackets, matches `::1` and `::`, and decodes the mapped form by its high byte, so the whole of the mapped 127.0.0.0/8 range is covered along with the mapped unspecified address. The dotted tail is still accepted for any engine that leaves it alone. Routable hosts are unaffected, pinned by tests for `[2001:db8::1]` and `[::ffff:203.0.113.7]`. Mutation-checked: dropping `::` and the mapped-IPv4 decode fails five tests and nothing else. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): normalize hostname and scheme spelling before the static verdict Two Codex P2s on #1364, both about trusting how a portal spells things. `http://localhost./ch/1234_` — a trailing dot is the DNS root and resolves identically, but `URL` keeps it for names while dropping it for IP literals (`127.0.0.1.` arrives bare, `localhost.` does not). The exact-name check read that as a remote host and would have pointed the player at its own loopback. Stripped before classifying. `HTTP://cdn.example/a.ts` — RFC 3986 makes the scheme case-insensitive. The case-sensitive tests failed SAFE, minting a link instead, but that defeats the contract for a portal that spells it this way, and one whose `create_link` cannot resolve an already-playable row would break. There were five such tests, and only one was on the new static path: the other three live in `resolveStalkerPlaybackUrl`, the create_link RESPONSE resolver, where `ffrt3 HTTP://…` failed to split its solution prefix and a query-only reply was appended to the portal base instead of to the command. That is pre-existing, but it is the same bug in the same shared normalizer, and fixing only the half this PR introduced would leave exactly the divergence this PR keeps removing. All five now go through one `hasHttpScheme()`. The response resolver had only indirect coverage, so it gains a direct spec alongside the static-path tests. Mutation-checked: reverting the dot strip and the case-insensitive scheme fails ten tests and nothing else. Also carries a docblock fix noticed on a read-through: the guard list still pointed at `PORTAL_LOCAL_HOSTNAMES` after the logic moved into `isPortalLocalHostname`, which now covers considerably more than that set. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): normalize DNS root dots in the shared credential classifier Codex P2 on #1364, extending the `localhost.` fix into `isStalkerStreamCredentialSafe()`. It compared hostnames literally, so a portal on `portal.example` serving `https://portal.example./movie.mkv` classified its own stream as third-party. Wider than the download guard it was reported against: this predicate is the single rule BOTH the renderer playback-header builder and the Electron main-process fallback use to decide whether a stream may carry the mac cookie and Bearer token. A portal-owned stream spelled with the root dot was getting the credential-free profile and would 401 — pre-existing, and exactly the "only VLC works" class this contract exists to prevent. My PR added two new dependencies on the same predicate (the download static guard and the portal-owned fallback), which is how it surfaced. Both sides are normalized, so it stays symmetric, and it can only widen toward "same host" — never toward handing credentials to a different one. A test pins that `evil.portal.example.` is still rejected. Also carries the authority guard found by probing the same class myself rather than waiting for it to be reported: `http:///ch/1` has no authority and `URL` quietly reinterprets the first path segment as the host, so a malformed command reached the player as a nonsense address instead of going to the portal. `isPlayableHttpUrl()` now requires a non-empty authority. The other exotic spellings I probed were already covered — `URL` canonicalizes `127.1`, `2130706433` and `0x7f000001` to `127.0.0.1`, uppercases and expanded IPv6 normalize too. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * perf(stalker): classify the static url before authenticating Codex P2 on #1364. Both static call sites awaited the session warm-up and only then asked whether the stream needed portal credentials at all — so a movie or channel on a foreign CDN paid for a handshake whose result was immediately discarded. That is not free: non-`create_link` requests carry a 15 s timeout (`stalker.events.ts`), so a portal that is slow or offline stalled playback of a stream the CDN would have served instantly. Cold Favorites/Recently Viewed starts are exactly where this bites, since that is where the session is not warm already. Classification now runs first. Foreign host returns immediately, portal-owned still warms and still falls back to `create_link` without a usable session. Behaviour is otherwise unchanged; only the order and the wasted wait are gone. Two tests moved with it: the foreign-host case now asserts the portal is not contacted at all rather than merely not asked for a link, and the repaired-endpoint case had been written against a foreign-host command, which under the new ordering correctly never reaches the handshake it was meant to be testing — it uses a portal-owned command now. Mutation-checked: restoring warm-before-classify fails the foreign-host test alone. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(stalker): repoint two handshake tests at the path they claim to cover Self-audit, prompted by the previous round: the reorder exposed one test that was asserting through a path it no longer reached, so I checked the rest of that class rather than assume it was the only one. Two more had the same defect, both mine. `still returns the static url when the handshake fails` (both specs) mocked `ensureToken` to reject, but used a FOREIGN-host command. Now that classification runs before authentication, that command returns before the handshake is ever attempted — the rejection was never exercised and the test passed on the early return instead of the mechanism in its name. Worse, the foreign case is already covered by the test added alongside the reorder, so these were asserting nothing new. Both now use a portal-owned command, which is what actually reaches the handshake, and assert what a throw really produces: `ensureStalkerSession` swallows it, the verdict is false, and the row falls back to `create_link` rather than being served as a known 401. Each asserts `ensureToken` was in fact called, so neither can silently drift back into testing an early return. Docs corrected with them: the "best-effort degrades to the token-less header set" wording described behaviour the reorder removed. A foreign-host URL is now returned before any handshake, and a failed one routes to `create_link`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(stalker): make the simple-portal skip test prove portal mode Fourth test found passing through the wrong exit, from auditing all ten in the block rather than waiting to trip over another one. `skips the handshake for a simple portal` used a foreign-host command, so the classification step returned before the warm-up was reached. `ensureToken` was indeed not called — but because the host was foreign, not because the portal was simple, and the assertion could not tell those apart. The command is now portal-owned, so the skip can only come from the mode, and the test also pins the returned URL and that no request was made. Mutation-checked properly this time: removing the simple-portal early return from `ensureStalkerSession` now fails this test. Under the old command it would not have. Also records the pattern where the next person will meet it. The decision chain has several exits — no flag evidence, unresolvable command, `series` set, foreign host, unusable session — and more than one can satisfy the same assertion, so a foreign-host command silently stands in for "simple portal" or "handshake failed". Mutation testing does not catch that class: it proves a test is coupled to its target, not that it reached the mechanism it names. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): key the radio fallback on flag evidence, not snapshot presence Codex P2 on #1364, and a divergence I introduced myself. `withStalkerPlayer`'s radio branch checks `hasStalkerLinkFlagEvidence(item)` before synthesizing the zero flags. `StreamResolverService` used `??`, which only falls back when the snapshot is absent entirely. A radio Favorite or Recent row persisted before the flags were carried HAS a snapshot — the old whitelist just stripped the flags out of it — so the `??` selected that flagless object, the helper found no evidence, and the collection route began minting for exactly the rows that used to play directly. That breaks portals whose radio `create_link` is unsupported, which is the case the radio exception exists for. The two paths now apply the identical rule. The divergence came from fixing them in different rounds and is precisely the class this PR keeps closing, so the comment on each side now points at the other. The existing radio test carries no `stalkerItem` at all, so it exercises the missing-snapshot arm and stayed green throughout — the same "passes through a different exit" pattern documented in the section above. The new test supplies a present-but-flagless snapshot. Mutation-checked: restoring the presence check fails it alone. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stalker): treat every reserved localhost name as portal-local Codex P2 on #1364, the fourth in this class. RFC 6761 §6.3 reserves `localhost` AND every name ending in `.localhost` for the loopback interface, and resolvers honour it — so `http://stream.localhost/ch/1234_` reached the player's own machine instead of being sent to the portal to resolve. Closed the class rather than adding one more name: the suffix is matched, and `localhost.localdomain` goes in with it as the conventional `/etc/hosts` alias for 127.0.0.1 on most Linux systems. Together with the earlier rounds the predicate now covers `localhost` and `*.localhost`, `localhost.localdomain`, `127.0.0.0/8`, `0.0.0.0`, `::1`, `::`, the IPv4-mapped forms `URL` rewrites to hex, and a terminal DNS root dot on any of them. Only the suffix is reserved, so the guard must not over-match: tests pin that `localhost.cdn.example` and `notlocalhost` remain ordinary routable names and keep playing statically. Mutation-checked: dropping the suffix rule and the localdomain alias fails four tests and nothing else.
