Fix the 8 fourth-round Codex findings that reached main with #3 - #4
Codex posted a fourth review round on e7dcc61 about 17 minutes before #3 squash-merged, so its 8 findings reached main without fixes. This PR fixes all 8, each with a test. Every finding was traced to a real input before fixing.
Reviewing this PR raised 13 more findings, from CodeRabbit and Codex. 11 are fixed. Two are left for the owner:
Hash-migration thread (src/monitor.zig): still open; the reasoning is on the thread.
SPDX header on CHANGELOG.adoc: licence edits are owner-only under the estate rules.
The PR also re-pins the deed to canon 2.1.4, released by standards while this PR was open (main has the same stale pin). It brings docs/status/ROADMAP.adoc up to date now that #3 has merged.
Changes
Web UI and configuration
Use-after-free of configuration error text (src/app.zig). config.Diagnostic now keeps its text in its own fixed 512-byte buffer, which truncates if needed. Before, the text lived in the parse arena, which App.load freed on the error path before the CLI printed the message. I reproduced this first: under the poisoning test allocator, main's code reads the message back as UUUU….
Cross-site GET marked items read (src/web.zig). /item/N now marks the item read only when the browser's Fetch Metadata shows a same-origin or user-typed navigation: Sec-Fetch-Site: same-origin|none with Sec-Fetch-Mode: navigate. All other cases leave the item unread, and the page then shows a POST Mark read button:
an <img> or link on another site
a same-site page on another local port
a client that sends no Fetch Metadata
a prefetch or prerender, which gets a 503 so the real visit is a fresh request
I chose this over POST-only read marks. Both close the hole, but this one keeps "open = read" and ordinary links (open in new tab, copy link).
web.bind the listener cannot use (src/config.zig). check-config now rejects a host name such as localhost. It also rejects a non-loopback address unless allow_non_loopback is set. isLoopback moves to config.zig and classifies the parsed address, not its spelling: 127.0.0.0/8, ::1 in any form, and ::ffff:127.0.0.0/104.
Monitor and feed parsing
cert_warn_days: 0 (src/monitor.zig, src/cli.zig, src/web.zig). Zero turns the certificate check off as documented: no probe and no alerts. The saved status is cleared, and both status views hide it even before that poll (monitor.shownCertNotAfter).
RSS item URL (src/feed.zig). The URL is chosen in this order:
The first RSS <link> with text, even when an atom:link comes before it.
Otherwise an atom:link href, when its rel is absent or alternate (compared case-insensitively, RFC 8288) and it is http(s) or relative.
Otherwise the guid, but only if it is a permalink; rdf:about counts as one, per RSS 1.0.
Price < 10 swallowed by change hashing (src/monitor.zig). < is treated as markup only when the next character could start a tag. tagOpener moves to util.zig, and store.plainText uses the same function.
The file did not load at all. selur-compose parses with toml 0.8 (TOML 1.0), which rejected the template's multi-line inline tables. The environment tables are now single-line, and a toml 0.8 parse passes.
Sets HERON_CONFIG and HERON_DATA, replacing the template's unused APP_* variables.
Mounts ./../heron.json read-only. selur's validator treats any volume that does not start with ./ or / as a named volume.
Publishes the port on 127.0.0.1 only, and drops the curl /health check heron cannot satisfy.
Documents that the rokur/svalinn gateway path cannot reach the UI as configured. A fronting proxy must forward Host and a matching Origin. The alternative is just container-keep oci portable.
Repository
heron-polyfeed-reader_chora.deed: canon re-pinned to 2.1.4. Only the version moved; the criteria and gates hashes are unchanged.
docs/usage.adoc, docs/architecture.adoc and CHANGELOG.adoc updated.
ROADMAP.adoc gains:
a summary of the review rounds
the code-owner self-review merge blocker
where the signed milestone history lives (refs/pull/3/head)
upstream candidates for standards, rsr-template-repo and metadatastician/selur
a robots.txt-change alert as a feature idea

eight guid/link shapes, plus webOrRelative
the web e2e test: cross-site, same-site, no Fetch Metadata, prerender, same-origin and none
config rejections and loopback classification
normalizeText with Price < 10
cert_warn_days: 0, including cached status and the view helper
ReleaseSafe build, then heron check-config:
Passes both example configs.
Accepts 0:0:0:0:0:0:0:1 and ::ffff:127.0.0.1.
Rejects 10.0.0.1, localhost and a missing file, with intact messages.
compose.toml parses with the toml 0.8 crate that selur-compose uses.
The canon lockstep comparison was re-run locally against the live canon.lock. The CLAUDE.md and coaptation verifiers pass (nickel 1.17.0).
CI on the head (c4c701a) is green across the board, including Canon lockstep and estate-audit.
Not verified: how selur resolves ./../heron.json at run time. selur is not available here.
Screenshots
$ heron check-config --config bad.json # {"web":{"bind":"localhost"}}
error: InvalidConfig: web.bind must be a numeric IP address such as 127.0.0.1 or ::1, not a host name
$ heron check-config --config /nonexistent.json
error: ConfigNotFound: cannot read config file /nonexistent.json
Codex posted these on e7dcc61 about 17 minutes before #3 merged, so they
reached main unaddressed. Each was traced to a real input; none declined.
Soundness:
- config.Diagnostic now owns its text (fixed 512-byte buffer, truncating)
instead of pointing into the parse arena, which App.load frees on the
error path before cli.run prints the message. Reproduced first: under
the poisoning test allocator main's code reads the message back as
"UUUU..."; the new app.zig test passes. bad() and the get*/rejectUnknown
helpers no longer take an allocator they do not use.
Security:
- web: GET /item/N marks the item read only for a navigation the browser
labels same-origin or user-typed (Sec-Fetch-Site: same-origin|none and
Sec-Fetch-Mode: navigate). An <img> or link on another site, a
same-site page on another local port, or a client sending no Fetch
Metadata leaves it unread, and the page then offers a POST "Mark read"
button (covered by the existing Origin check). Chosen over POST-only
read marks to keep "open = read" and ordinary links (new tab, copy).
e2e test covers cross-site, same-site, absent, same-origin and none.
Configuration:
- check-config rejects a web.bind the listener cannot use: a host name
("localhost") or a non-loopback address without allow_non_loopback, so
a passing check no longer hides a UI the daemon then disables.
isLoopback moves to config.zig; web.zig re-exports it.
- cert_warn_days: 0 is "off" as documented: no probe and no alerts, the
expired case included (test).
Correctness:
- feed: without a text <link>, an atom:link (rel absent or alternate)
is used before the guid, and a guid is used only when it is a
permalink (isPermaLink absent or true; rdf:about counts, per RSS 1.0).
Test covers all four shapes, including a rel=self link that is ignored.
- monitor.normalizeText treats '<' as markup only before a plausible tag
opener, so "Price < 10" is hashed text and a change after it alerts.
tagOpener moves to util.zig and serves store.plainText too.
Containers:
- build/container/stapeln/compose.toml (selur, Tier C): HERON_CONFIG /
HERON_DATA instead of the template's unused APP_* variables, mounts
../heron.json read-only, publishes on 127.0.0.1 only, and drops the
curl /health check heron cannot satisfy.
Docs: usage.adoc (web.bind, cert_warn_days 0, the read-mark rule),
architecture.adoc, CHANGELOG; ROADMAP brought to the merged state (review
summary, code-owner self-review blocker, where the signed milestone
history lives, upstream candidates, robots.txt-change feature idea).
Verified: zig build test 94/94 (main: 92); zig fmt --check clean;
ReleaseSafe build; check-config passes both example configs and rejects
"localhost" and a missing file with intact messages; local gates
check-adoc-renders (157 files), check-root-shape, check-no-placeholders
and the repo-map regeneration pass. Not run here: the CLAUDE.md verifier
(nickel absent in this container; deed and CLAUDE.md are unchanged).

The changes update configuration diagnostics and validation, item read marking, RSS URL selection, monitor checks, and container settings. Tests and documentation cover these changes. The changelog and roadmap record review-round updates.
Changes: Application behavior changes
Layer / File(s)
Summary
Configuration diagnostics and bind validation src/config.zig, src/app.zig, src/cli.zig, src/web.zig, docs/usage.adoc
Diagnostics now use a fixed buffer. Web bind parsing requires a numeric IP address and applies loopback restrictions unless non-loopback binds are allowed. Callers, tests, and documentation use or describe the updated behavior.
GET requests mark items read only for qualifying navigations. Other requests leave items unread and display a POST action. Requests identified as prefetch receive 503 responses.
RSS item URL selection src/feed.zig
RSS parsing prefers a text link, then an eligible alternate href, and then a qualifying HTTP-prefixed GUID. Tests cover link precedence and GUID conditions.
Monitor text and certificate checks src/util.zig, src/store.zig, src/monitor.zig, docs/usage.adoc
Store and monitor parsing use the shared tag-opener helper. Text normalization preserves less-than signs that do not begin tags. A zero cert_warn_days setting skips certificate probes and clears saved certificate status.
Container and review records
Layer / File(s)
Summary
Container settings and review-round records build/container/stapeln/compose.toml, CHANGELOG.adoc, docs/status/ROADMAP.adoc, docs/architecture.adoc
The Heron container publishes port 8484 on host loopback, mounts configuration read-only, and no longer defines a healthcheck. The changelog and roadmap record review-round updates. The architecture line has no content change.

Explanation
The title names the work as fixing the eight fourth-round Codex findings that reached main with #3. The changeset does address those findings across src/app.zig, src/web.zig, src/config.zig, src/monitor.zig, src/feed.zig, the selur compose stack, and the docs. The title is specific, but it frames the change by its origin and does not name the fixes themselves, such as read-marking, loopback bind validation, or the diagnostic lifetime fix. That makes it partially descriptive rather than the main change in plain terms. It is also a single sentence without emojis or file lists, so it meets the length and clarity principles.
Full details: Description check
Explanation
The description follows the repository template closely. It has Summary, Changes, the RSR Quality Checklist, Testing, and Screenshots sections. The Summary explains the PR's purpose and the eight fourth-round findings it fixes. The Changes section lists the fixes by file. The checklist records test results, formatting, and the reasons for unchecked items. The Testing section gives concrete commands, counts, and manual checks. Two gaps remain. The Summary does not use the template's "Closes #N" link form, and the description says CodeRabbit and Codex findings were partly left open. The description also states a test count of 95/95, while the objectives state 94/94. These are minor inconsistencies that the author should reconcile. The template's required SPDX check applies to new or modified source files, and the description says none are new. The description covers the template's required content and gives reasons for each unchecked item.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Reject speculative prerenders before marking items read.
Chrome can prerender an item while the user types in the address bar or hovers over a bookmark. Such a request can contain Sec-Fetch-Site: none and Sec-Fetch-Mode: navigate, so this gate marks the item read even if the user never opens it. (github.com)
Detect Sec-Purpose: prefetch;prerender and return a non-2xx response so a later navigation retries normally.

Each verified before fixing:
- web: a prefetch or prerender of /item/N (Sec-Purpose or Purpose
containing "prefetch") is answered 503, which cancels the prerender. A
browser can prerender a typed URL or a hovered bookmark with the same
"none"/"navigate" Fetch Metadata as a visit, so before this it could
mark an item read that was never opened; now only the real visit, a
fresh request, marks it. e2e test added.
- feed: every link child of an RSS item is looked at in document order and
the first with text wins, so an atom:link before the RSS <link> no
longer hides it; the href fallback compares rel case-insensitively
(RFC 8288). Two test shapes added.
- compose.toml (selur): "./../heron.json" instead of "../heron.json".
Confirmed in metadatastician/selur compose/src/compose.rs: a volume not
starting with "./" or "/" is taken as a named volume and the stack fails
validation with "unknown volume". Recorded as an upstream candidate.

Codex on 4da01b2: isLoopback compared text, so 0:0:0:0:0:0:0:1 (a valid
spelling of ::1) needed allow_non_loopback. It now parses the address and
decides on its value: 127.0.0.0/8, ::1, and IPv4-mapped ::ffff:127.0.0.0/104.
A side effect is that "127.evil" is no longer loopback by prefix. Tests
cover both spellings, the mapped form, ::, ::2, a mapped non-loopback,
127.evil and localhost; the ReleaseSafe binary's check-config accepts
0:0:0:0:0:0:0:1 and ::ffff:127.0.0.1 and still rejects 10.0.0.1 and
localhost. zig build test 94/94; zig fmt --check clean.

Codex on 4da01b2:
- monitor: switching an existing monitor to cert_warn_days 0 now clears
cert_not_after, cert_checked and cert_alert, as check_robots=false
already clears `blocked`; otherwise `heron monitors` and /status kept a
stale countdown or EXPIRED for a check that no longer runs. Test: probe
at 14, switch to 0, all three fields reset.
- selur compose.toml: the rokur/svalinn gateway path cannot reach the UI
as configured (heron's Host allowlist refuses the gateway's Host).
Rokur's documented settings (metadatastician/rokur README) have no Host
rewrite, nor the ROKUR_BACKEND the template sets, so no setting is
invented here; the stack now says so, as compose.yaml does, and names
`just container-keep oci portable` to drop the tier. Recorded in the
roadmap's rsr-template-repo upstream note.
Verified: zig build test 94/94; zig fmt --check clean; check-adoc-renders,
check-no-vlang, check-root-shape pass.

Migrate or baseline saved hashes when normalization changes.
The monitor persists State.hash without a normalization version or baseline marker. When a deployment retains existing state, an unchanged body such as <p>Price &lt; 10</p> can produce a different hash after this normalization change and emit CHANGED. That alert also updates last_change, so a real change can be suppressed for one hour. Establish a new baseline for hashes created by the previous normalizer.

The path is real. After upgrading, a monitored page whose raw HTML has a < that can't open a tag (Price < 10) hashes differently from the hash saved by the old normaliser. So it raises one CHANGED alert, and that alert starts the one-hour suppression window.
I haven't built the migration here, for three reasons:
Scope of the harm. It's at most one spurious alert per affected monitor, once. Nothing is lost, and the next poll establishes the new baseline.
No deployed state. heron is experimental and has never run against live sites (docs/status/ROADMAP.adoc, Known gaps), so no deployment holds hashes from the old normaliser.
Ongoing cost. A versioned-hash scheme means a State field, baseline logic that also drops the saved ETag and Last-Modified, a test, and a rule to bump the version on every future normaliser change. That cost would last well beyond this one transition.
If the owner wants the versioned scheme now, it's a small follow-up. I'm leaving this thread open for that decision.
The reason will be displayed to describe this comment to others. Learn more.
@hyperpolymath Deferring the migration is reasonable given your report that no deployed state exists. I no longer recommend treating this as a major blocker for this PR.
The compatibility risk remains valid if old state is retained. One detail matters: a real change during the suppression window can lose its alert because st.hash still advances. A later poll does not necessarily recover that alert.
My original escaped-HTML example was incorrect. Raw HTML such as <p>Price < 10</p> demonstrates the issue.
I’ll leave the thread open for the owner’s decision. Would you like a follow-up issue for hash-baseline handling before deployed upgrades need support?

Each verified before fixing:
- build/container/stapeln/compose.toml: the environment tables were
multi-line inline tables with trailing commas, which TOML 1.0 forbids.
selur-compose parses with the toml 0.8 crate (metadatastician/selur
compose/Cargo.toml), and a toml 0.8 parse of the file failed at line 33
("invalid inline table"); it fails on main too (template defect). The
three tables are now single-line; the same toml 0.8 check now passes,
and every key matches selur's Service fields. The template's
compose.example.toml has the same defect; recorded upstream.
- compose.toml: the fronting-proxy note now also says the proxy must make
the forwarded Origin match the forwarded Host, or the UI's CSRF check
answers 403 to every POST.
- feed: an atom:link alternate is taken only when it is http(s) or
relative (webOrRelative), so an ftp: or mailto: alternate no longer
displaces a usable permalink guid. Unit test plus two item shapes.
- monitor.shownCertNotAfter: `heron monitors` and the web status page show
no certificate expiry while cert_warn_days is 0, even before the poll
that clears saved state (e.g. right after a restart). Test.

On CodeRabbit's finding outside the diff (an SPDX header for CHANGELOG.adoc): I'm leaving it out. This estate's rules make licence and SPDX edits manual and owner-only, never done by an agent. CHANGELOG.adoc also had no header on main before this PR. It's for the owner to add by hand if wanted.
The four other findings in that review are fixed in 4ac5fde and their threads are resolved. The normaliser-migration thread stays open for the owner's call; the reasoning is on that thread.
Canon lockstep failed on 4ac5fde after passing on 93e7ce4: between the two
runs hyperpolymath/standards released canon.lock 2.1.4 (PATCH: the
constitution files and TEMPLATE-APPLICABILITY-POLICY moved under 0-canon/).
The criteria and gates sha256 this deed pins are unchanged; only the
version moved, so :version goes 2.1.3 -> 2.1.4. main carries the same stale
pin, so this also fixes the check there once merged.
Verified by running the check's own deed_canon / canon_key / artefact_hash
helpers (from dogfood-gate.yml) against the live canon.lock: version,
criteria and gates all match. CLAUDE.md arrival pack and coaptation receipt
verifiers pass (nickel 1.17.0, as CI pins).

Summary
Codex posted a fourth review round on e7dcc61 about 17 minutes before #3 squash-merged, so its 8 findings reached
mainwithout fixes. This PR fixes all 8, each with a test. Every finding was traced to a real input before fixing.Reviewing this PR raised 13 more findings, from CodeRabbit and Codex. 11 are fixed. Two are left for the owner:
src/monitor.zig): still open; the reasoning is on the thread.CHANGELOG.adoc: licence edits are owner-only under the estate rules.The PR also re-pins the deed to canon 2.1.4, released by
standardswhile this PR was open (mainhas the same stale pin). It bringsdocs/status/ROADMAP.adocup to date now that #3 has merged.Changes
Web UI and configuration
Use-after-free of configuration error text (
src/app.zig).config.Diagnosticnow keeps its text in its own fixed 512-byte buffer, which truncates if needed. Before, the text lived in the parse arena, whichApp.loadfreed on the error path before the CLI printed the message. I reproduced this first: under the poisoning test allocator,main's code reads the message back asUUUU….Cross-site GET marked items read (
src/web.zig)./item/Nnow marks the item read only when the browser's Fetch Metadata shows a same-origin or user-typed navigation:Sec-Fetch-Site: same-origin|nonewithSec-Fetch-Mode: navigate. All other cases leave the item unread, and the page then shows a POST Mark read button:<img>or link on another siteI chose this over POST-only read marks. Both close the hole, but this one keeps "open = read" and ordinary links (open in new tab, copy link).
web.bindthe listener cannot use (src/config.zig).check-confignow rejects a host name such aslocalhost. It also rejects a non-loopback address unlessallow_non_loopbackis set.isLoopbackmoves toconfig.zigand classifies the parsed address, not its spelling: 127.0.0.0/8,::1in any form, and::ffff:127.0.0.0/104.Monitor and feed parsing

The saved status is cleared, and both status views hide it even before that poll (monitor.shownCertNotAfter).src/feed.zig).
