- verdict() now blocks file:/ftp:/gopher: subresources instead of allowing all
non-http(s) schemes (keeps data:/blob:/internal for page loads).
- bin/crawler.rs uses should_attach_safe_resolver() so an http(s) proxy keeps the
DNS-rebinding guard, matching the daemon.
- Regression test pins the url crate's decimal/hex/octal/short IPv4 normalization
to loopback (ensure_public_target rejects them). Tested.

Make explicit (config.rs + .env.example) that disabling the per-chapter page cap

Off-by-default left headless-browser page JS/subresources/redirects able to reach
internal IPs (Chromium bypasses the reqwest SafeResolver). The crawler runs in the
backend container so it can't be network-isolated without breaking Postgres — the
CDP Fetch interceptor is the control. Flip CRAWLER_SSRF_INTERCEPT default to true
(config + .env.example + compose); off-path unchanged as break-glass. The
#[ignore]'d smoke test validates against real Chromium (command documented).

put_cover/delete_cover mutated storage before the DB pointer, so a transient DB
failure could leave the row pointing at a deleted blob. Reorder to
put->set-DB->delete-old and clear-DB->delete-blob, so a failure only orphans a
blob, never dangles the pointer. Happy path covered by the 16 existing cover tests.

Deterministic per-page storage keys mean a re-crawl overwrites the image but the
pages row survives the upsert, so analysis keyed to page_id (page_analysis/
search_doc, OCR, auto-tags, content-warnings) stayed stale forever and
force=false re-enqueue never re-analyzed it — poisoning search + the derived
manga_content_warnings (audit DB-1). persist_pages now detects conflict-updated
pages via xmax and clears their four derived tables in the same tx (the
content-warnings DELETE fires the mcw_* triggers), returning them to unanalyzed
so they re-derive. Tested.

constant_time_eq (and the `subtle` dependency) was never wired into any
comparison — the module doc wrongly claimed token comparison used it, but lookup
is an indexed DB equality on the 256-bit SHA-256 hash, so there's no in-process
secret compare to time-attack. Delete the dead fn, its test, and the unused
`subtle` dep; rewrite the doc. No behaviour change.

The sessions table only grew — find_active ignored expired rows but nothing

- repo::session::delete_expired: indexed DELETE (sessions_expires_idx) returning

The /files handler served the application/octet-stream fallback with no
Content-Disposition, letting a browser render it inline — a stored-XSS vector if
the blob is crafted HTML/JS. Add Content-Disposition: attachment for that type

The `metadata` JSON part in the manga-create and chapter-upload handlers was
read with `Field::bytes()`, buffering the whole part before any check — a client
could send a multi-hundred-MB metadata blob (up to the 200 MiB request limit) as
one allocation. Image parts were already streamed with a cap; metadata was the
last unbounded read.
Cap it at a shared upload::MAX_METADATA_BYTES (64 KiB) via the read_capped
streaming loop (413 on overflow), and remove the now-unused read_field_bytes
helper so the unbounded path can't return.
Tests: manga + chapter oversized-metadata parts are rejected with 413.

`get` (fs::read → EISDIR) and `get_stream` (File::open succeeds on a Unix

IsADirectory to NotFound; `get_stream` checks metadata.is_file() after open.
Test: get_on_directory_is_not_found.

A `%` or `_` in a search term silently acted as a LIKE wildcard rather than
matching literally (`50%` matched everything, `a_b` matched `axb`). Not
injection — terms are bound — but a search-correctness bug across every
user-facing ILIKE site.
- repo::escape_like: shared pub(crate) escaper (promoted from page_tag), unit-tested.
- Trigram-entangled sites (manga, tag, author) append a separate escaped param
used only by the ILIKE branch; the trigram/similarity branches keep the raw term.
- Pattern-built sites (admin manga list, admin users, analysis coverage + history,
crawler search incl. JSONB payload title) escape inside format!("%{}%", ..) and
pair each ILIKE with ESCAPE '\'.
Tests: escape_like unit tests + integration tests on public manga search, author
autocomplete, and admin user search proving `_` matches literally.

The account page pointed users at a "bot-token list" that didn't exist: there
was no GET endpoint, no UI route, and the client type lacked expiry. Add
GET /v1/auth/tokens (caller-scoped, token_hash never serialised), extend the
auth client with listTokens/expires_at and createToken expiry, and add a
/profile/tokens page to list, create (revealing the raw bearer once), and
revoke tokens. Link the account-page copy to it.

Add /files/{key}?w=<px>: the endpoint decodes JPEG/PNG sources, downscales to
a width snapped to a small allow-list (aspect-preserving, never upscaling),
caches the result under a thumbs/ prefix, and serves it — so cover grids
download ~KB instead of the 1–5 MB original. Cover handlers purge cached
variants when a cover (whose key is reused) is replaced or deleted. Frontend
grids use new thumbUrl/thumbSrcset helpers (MangaCard with responsive srcset).

?sort=author used a correlated min(lower(a.name)) subquery as the ORDER BY
key, evaluated per filter-matching row before LIMIT. Materialize it into
mangas.sort_author (indexed by mangas_sort_author_idx), maintained by triggers
on manga_authors and backfilled in the migration, so the sort is a plain
indexed column read. Author names are immutable, so only join changes matter.

The content-warning include/exclude filter (and its count) ran a correlated
page_content_warnings->pages->chapters join per candidate manga — O(mangas *
pages) on every filtered list. Add a manga_content_warnings(manga_id, warning)
table holding each manga's deduped warning union, maintained by triggers that
recompute an affected manga's set (delete+reinsert of the tiny five-label set,
robust across page/chapter/manga cascade deletes), backfilled in the migration.
The filter is now a single indexed lookup.

Uploaded chapters have no source_index, and ORDER BY source_index DESC NULLS
LAST sorted every one of them after all crawled chapters regardless of number
— an uploaded chapter 5 landed after crawled chapter 100. Slot each uploaded
chapter by number, just before the crawled chapter with the smallest greater
number, so it interleaves. Crawled rows keep their reversed source-DOM order,
preserving the deliberate placement of non-numeric entries (migration 0021).

Re-adding an already-bookmarked manga returned 409, which the UI surfaced as
a false "Could not add bookmark" toast — collections are idempotent, bookmarks
weren't. On a unique violation, fetch and return the existing bookmark, and
answer 200 (vs 201 for a fresh insert). The frontend toggle already treats a
successful POST as done, so the false toast disappears with no client change.

The first guard block computed the partial-render condition but had an empty

try_acquire used .expect on lock(), so a single panic while holding either

Heartbeat renew failures were only logged, so under DB flakiness a job could
be leased twice concurrently — the original worker kept crawling past a lapsed
lease while another re-leased it. Track consecutive renew failures and, after
MAX_HEARTBEAT_RENEW_FAILURES, signal the worker (via a CancellationToken) to
abandon the in-flight dispatch instead of working a job it no longer owns.

An idle worker re-issued a row-locking lease query every 1s per worker with
no backoff. Replace the flat sleep with idle_backoff: 1s, 2s, 4s, … capped at
30s, reset to 0 the moment a job is leased, so a quiet daemon stops hammering
the crawler_jobs table.

A job's attempt is incremented at lease time, then the dispatcher acquires
the headless browser. When the browser was down or mid-restart, acquire()
failed and the error was ack_failed — so during an outage the whole pending
backlog was chewed to `dead` within minutes while workers hot-looped.
Add SyncOutcome::BrowserUnavailable: the dispatcher returns it instead of
propagating the acquire error, and the daemon releases the lease (refunding
the attempt, like the cancel/session paths) and backs off, so an outage is
treated as an infrastructure blip rather than per-job failures.

The cover multipart path called Field::bytes(), buffering the entire field
into memory before parse_image checked max_file_bytes — an oversized cover

chunk is never copied in), and route both cover handlers and stage_image_part
through it.

Commit 134ab54 dropped the safe DNS resolver for any configured proxy, but
that guard is only pointless for SOCKS proxies (where the proxy resolves the
target). On an http(s):// proxy reqwest still resolves the target locally, so
a hostname resolving to a private IP would be reachable. Narrow the exemption
to SOCKS-only via should_attach_safe_resolver.

The CDP Fetch interceptor only paused main-frame Document requests, so a
scraped page's <img>/fetch()/XHR subresources to internal targets
(169.254.169.254, postgres:5432, RFC1918) reached those hosts unguarded.
Drop the ResourceType::Document constraint so every request runs through
is_blocked. Also make open_page fail-closed: if the guard can't install,
close the blank page and return the error instead of navigating unguarded.

ff4ca96 wired SafeResolver (drops any host resolving to a private IP) into
all four crawler/analysis reqwest clients. That broke every proxied fetch:
with a socks5h:// proxy the target is resolved by Tor, so reqwest only ever
resolves the proxy's OWN host — `tor`, on a private Docker IP (172.x) — which
the resolver then rejects ("SOCKS error: failed to create underlying
connection"). 100% of crawler image downloads failed. The vision clients
broke the same way against `mangalord-vision` (latent; analysis was off).
Fix: attach the resolver only on the crawler's direct (unproxied) path, where
it genuinely guards DNS rebinding. Behind a proxy it adds no protection (Tor
can't reach internal ranges and the target is invisible to reqwest) so it's
omitted. Drop it from the vision clients entirely — that endpoint is an
operator-configured internal service that must resolve to a private IP.
Security posture is >= the pre-ff4ca96 baseline (which had no resolver at all).
is_private_ip / retain_public_addrs and their tests are unchanged.

A single global token bucket let one attacker at the sustained rate 429
every user's login/register/change-password. Key buckets by client IP: the
SvelteKit proxy now stamps the real peer address onto X-Forwarded-For
(overriding any client-supplied value, anti-spoof), and axum reads it via a
ClientIp extractor — but only when AUTH_TRUSTED_PROXY is set, else it falls
back to the shared bucket (today's behavior). The per-IP map is bounded
(10k IPs, idle buckets pruned) so a spoofed-IP spray can't grow it.
AUTH_TRUSTED_PROXY defaults false (safe for a directly-exposed backend);
compose sets it true since the proxy is the single trusted hop.

The reqwest DNS resolver can't see Chromium navigations, so a scraped page
that redirects the browser to an internal target (302 -> 127.0.0.1:5432, or
a rebinding hostname) was still loaded. Add crawler::intercept: an opt-in CDP
Fetch guard that re-validates every Document navigation/redirect through the
same ensure_public_target + resolved-IP check, failing internal targets.
Gated behind CRAWLER_SSRF_INTERCEPT (default OFF): enabling Fetch is a fragile
critical-path hook and the CDP wiring is not CI-verifiable (no Chromium in
CI). When off, open_page is byte-identical to browser.new_page; when on, a
guard-install failure falls back to an unguarded navigation rather than
wedging the crawl. The pure decision logic (verdict/is_blocked) is unit-tested;
an #[ignore] smoke test covers the CDP path. Validate with a manual crawl
before enabling in production.

The SSRF guard only checked the host string, so an attacker-owned domain
resolving to 169.254.169.254 / 10.x (DNS rebinding, TOCTOU) bypassed it.
Add a reqwest dns::Resolve (SafeResolver) that drops resolved addresses in
private ranges, wired into all four crawler/analysis clients — it fires per
connection so it also covers redirect hops. Also close the is_private_ip
IPv6-embedding gaps (IPv4-compatible ::/96, NAT64 64:ff9b::/96, 6to4
2002::/16 all now unwrap to the embedded IPv4).

The immutable Cache-Control added for the reader preload work was

GET /mangas recomputed count(*) over FILTER_WHERE (up to five correlated

new_page() opened a tab that was only closed on the happy path; a `?` on

A "Continue reading" shelf listing series the reader already finished (read

new_chapters_count over-counted when scanlations share a chapter number
((manga_id, number) is non-unique, migration 0013): COUNT(*) tallied rows,
so duplicate-numbered chapters inflated the badge. Switch both the list and
per-manga read-progress queries to COUNT(DISTINCT number), and drop the dead
COALESCE (an empty set counts as 0, and the NULL-number case is handled by
the predicate). Fix the misleading comment.
Expose new_chapters_count on GET /me/read-progress/:manga_id and drive the
detail page's "N new" badge from it, instead of recomputing over the

loaded chapters and are documented as by-number (all we persist).

Add `new_chapters_count` to each `GET /me/read-progress` item: how many
chapters sit past the reader's last-read chapter, computed by a correlated
subquery on chapter number. It is 0 when the reader is caught up, and 0
when the last-read chapter is unknown (manga-level progress or a deleted
chapter) so we never over-claim. (manga_id, number) is non-unique, so this
counts positions past the reader rather than distinct files.

The chapter upload handler read every `page` part fully into a Vec before
writing any, so peak memory was the whole chapter (bounded only by the
200 MiB body limit and amplified by concurrent uploads). It also accepted
an unbounded number of pages.
Stream each page part to a `staging/{upload_id}/…` key as it arrives — at
most one page's bytes are held at a time — then, once the chapter row (and
its id) exists, promote each staged blob to its final key via a new
`Storage::rename` (LocalStorage: fs rename; default impl: stream+delete for
future backends). Finalization is all-or-nothing: on any failure the DB
rolls back and both staged and already-finalized blobs are cleaned up.
Add MAX_PAGES_PER_CHAPTER (UploadConfig, default 2000, 0 = disabled),
rejecting an over-cap upload with 413 before any DB write. Also document
the crawler-side CRAWLER_MAX_IMAGES_PER_CHAPTER (added earlier) in
.env.example + docker-compose so the env-coverage test passes.
Tests: LocalStorage rename unit tests; a 413 over-cap upload test; existing
rollback + happy-path upload tests still green (the fault-injecting storage
counts put/put_stream, so mid-upload failure still rolls back).

The retention reaper deleted only `state = 'done'` rows, so terminal

`state IN ('done','dead')`; `pending`/`running` stay untouched. Test
