Per Codex. Pool grown 51/44 → 115/104 hopeful answers (5/6 letter) via the
agreed workflow: LLM proposes themed candidates → code filters to the bundled
guess dictionary (length/alpha/dedup) → human spot-check prunes tone-drift
("growl", "plain", "color"…). ~3.5-month runway before repeats per variant.
test_wordpool.py locks the invariant in CI: every answer must be lowercase
alpha, correct length, unique, and present in words-5/6.json — so no future
addition can become an unguessable puzzle.

A calm /play space — "after the brief, a small thing to enjoy." Framework-ready
for more games (Word Search next; zen/coloring later).
* Daily Word (5 letters / 6 guesses) + Long Word (6 / 7) — same Wordle mechanic,
Upbeat Bytes flavor (no "Wordle" in the UI). Hopeful answers; after solving, a
one-line "why this word matters."
* LLM proposes, code disposes: answers are picked deterministically by date-seed
from a hand-curated hopeful pool that's pre-validated ⊆ the guess dictionary
(always typeable), avoiding recent repeats; the LLM only adds the optional
"why" (with fallback). daily_puzzles(date, game, variant, payload) stores them
so everyone gets the same daily; the cycle pre-generates with the "why".
* Bundled guess dictionaries (words-5/6.json, ~12.6k/22.4k) for client-side guess
validation — never the LLM. Answer lightly obfuscated (base64) in the payload.
* Private, gentle stats (played/solved/streak, guess distribution); spoiler-free
emoji-grid share. No leaderboard, no timer, no streak-loss drama.
* Play in the bottom nav (replacing Browse, still on the lane rail) + the header.

Two calm returning-reader features.
Since-last-visit (Highlights companion, not a nav lane — per Codex):
* queries.feed gains a `since` filter; GET /api/since?ts= returns the count +
a few accepted/non-dup/visible articles discovered since the reader's last
visit (boundary-respecting; invalid/future ts → 0, no error).
* Home stores last_seen in localStorage (reads prev, then stamps now); on
Highlights, a gentle "Since you were last here, N new calm reads came in"
note with a "See what's new" reveal of a compact inline section. Dismissible.
No badges, no unread counts, no "missed" language.
PWA:
* Real PNG icons (192/512 + full-bleed maskable) rasterized from favicon.svg;
manifest fixed (azure theme to match the brand, PNG icons); apple-touch-icon.
* Minimal service worker: precache the app shell, always-fresh API + /a/ pages.
* Gentle, dismissible install banner (beforeinstallprompt → Install; iOS → the
Share → Add to Home Screen hint). Never nags.

Per Codex: generate_summary treated why_belongs alone as a complete explanation,
but get_explanation requires all three — so a partial older row (e.g. only
why_belongs) would never top up and the page would fall back forever. Now the
fully-cached check requires summary + what_happened + why_matters + why_belongs.
Test covers the partial-row top-up.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — make /a/<id> feel like Upbeat Bytes has editorial judgment, not just
a summary wrapper. Trust-building, short, not an essay.
* article_summaries gains what_happened / why_matters / why_belongs (+ migration).
* summarize.explain_article: a separate, fallback-able LLM pass producing three
short notes (parsed from a labelled WHAT/MATTERS/BELONGS format). generate_summary
now stores them alongside the summary, and tops up older summaries on next view.
get_explanation returns them only when all three are present.
* API: share_page + /api/summary expose the explanation.
* share.py: renders the three-part section (accent rule) when complete; otherwise
the single "Why it's here" reason line is the calm fallback. The page polls and
swaps in both the summary and the section as they cache.

Per Codex — guard against the static logo silently going missing (which would
break the newsletter masthead). Non-fatal curl check after Caddy reload.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per user — a heavier, darker divider (2px #9aa6b2) marks the brief→personal
section change, distinct from the light #e8e3d8 item separators above.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per user — separate the heading a touch more from the first followed entry
(bottom margin 18px → 28px).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
It was 11px uppercase — smaller than the 14px links, backwards for a heading.
Now 20px bold ink, clearly a section header above its items.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — give follows an immediate payoff without making the email feel
algorithmic. The editorial brief stays the star: subject + brief count unchanged.
* followed_digest_items(conn, user_id, exclude_ids, limit=3): recent items from
the user's followed sources/tags, same accepted/non-dup/content-visible gate,
excludes anything in the brief, capped to one per source so a single follow
can't dominate. Empty → section omitted (no empty state in email).
* build_digest gains an optional `followed` list → a small "From what you follow"
section AFTER the brief, only when there are items. Item rendering factored into
shared _item_html / _item_text_lines helpers.
* send_due_digests computes the followed items per user (excluding the brief).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: saveLanes() bounced to Highlights if the current view wasn't in the
customizable keys, but Following is a special pinned lane (like today/latest)
that's never in keys. Add it to the special-lanes exclusion so editing the lane
picker while viewing Following no longer navigates away.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — turn accounts into a real reason to return, without an algorithmic
feed. Durable interests (sources + tags), not moods.
* DB: user_follows (user_id, kind source|tag, value, unique).
* queries.feed gains follow_sources/follow_tags → the Following feed is
"articles from a followed source OR carrying a followed tag", still respecting
calm filters/boundaries.
* API: GET/POST/DELETE /api/follows (sign-in required; source ids validated);
/api/feed?following=true resolves the user's follows (anon → empty, not error).
* Frontend: follows store (followKeys + toggleFollow, mirrors savedIds); a
Follow button on source + tag/topic views; a "Following" lane in the nav with
a tailored empty state; a Following management section in Account (unfollow).
Digest "From what you follow" deferred to v2 (brief stays first).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — cleanest, most brand-consistent option. Rasterized logo.svg to a
small transparent logo-email.png (360px wide, shown at 180px for retina), served
at /logo-email.png. alt="Upbeat Bytes" keeps the brand if a client blocks
images. SVG isn't email-safe; a hosted PNG is the standard approach.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per user — make the text masthead read as the brand: lowercase 'upbeat bytes'
with a space but tight letter-spacing (-0.045em, not standard), in the logo's
two colours (azure #0083ad + navy #002772). Closest email-safe echo of the logo
short of a hosted PNG.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per user: lowercase masthead to echo the logo's character (kept as text, not an
image — email clients strip SVG and block remote images, so text always renders
and degrades gracefully). More breathing room before the 'Good morning' intro,
and a horizontal divider after it to match the item separators. (Real logo PNG
remains an option if wanted.)
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per user feedback: rename from 'Today's good news' (which implied the site was
done for the day) to a publication-style 'Upbeat Bytes — Daily Highlights'
masthead with a warm morning intro and a sign-off that links back to the site
('more good news is always waiting'). Adds 'why it's here' to the plain-text
part too. No images by design (lightweight, mail-client-safe).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex polish: if someone taps 'Get tomorrow's brief' then dismisses sign-in
without authing, clear pendingDigestOptIn (guarded by !auth.user so a successful
sign-in still auto-enables via the $effect).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* On-site end-cap now says "You're caught up for now." — honest, since Highlights
refreshes through the day (the email keeps the daily "see you tomorrow").
* Anonymous "Get tomorrow's brief by email" now honors the one-tap promise:
sets a pending flag, opens sign-in, and auto-enables once auth resolves.
* Email compliance (RFC 2369/8058): send_email takes optional headers; the digest
sets List-Unsubscribe + List-Unsubscribe-Post=One-Click, and a POST
/api/digest/unsubscribe handles native one-click (GET still serves the page).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
On phones the feed is a single column, so the banner no longer needs to keep a
uniform grid height. Below 540px: trim photo banners (16/9 → 2/1) and shrink
image-less placeholders to a slim 54px topic-label band. Desktop/2-column
unchanged (uniform heights still matter there).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — a per-row Check button that previews a LIVE source on demand,
intentionally read-only and ephemeral.
* POST /api/admin/sources/{id}/preview — admin-gated, safe-fetch + heuristic
preview (reuses the candidate preview path), returns the result. Mutates
NOTHING: no DB write, no poll attempt, no health/state change. 404 on missing.
* UI: per-row Check button with a Checking… state; results in an inline row
under the source (sampled, would-pass %, recent-7d, example accept/skip
headlines) with dismiss; inline error on failure. "Checked just now" is
local UI state only. Heuristic v1 — model deep-check left for later.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — make the table more decision-ready from data we already have.
Paywall is a domain-level hint, so it's a per-source flag (not a meaningful
rate): show image-coverage % plus a 🔒 marker for subscription domains in one
compact "Media" column (tooltip spells it out). source_health gains a
`paywalled` flag (is_paywalled on homepage/feed); also added to sources.csv.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: outgoing reply now sets Reply-To = GOODNEWS_REPLY_TO_EMAIL, falling
back to the From address. Never the reader's own address (they're the recipient).
send_email gained an optional reply_to param. Failed-send stays UI-only (draft
kept) — no schema change, per Codex's lean.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: source-controlled strings (name, feed_url, last_error, review_reason)
could be read as formulas by spreadsheet apps if they start with = + - @. Add
_csv_cell — prefixes such strings with an apostrophe; numbers pass through
untouched (no risk, and avoids mangling negatives). Routed every exported cell
through it. Test: a =HYPERLINK(...) source name is escaped, never bare.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex v1 — boring-in-the-best-way: inspect/archive operational data outside
the app. Admin-gated, Python csv module, text/csv + attachment disposition.
* GET /api/admin/export/sources.csv — current-state snapshot per source: name,
feed/homepage, status, visible, served/accepted/total, acceptance/duplicate/
accepted-dup/image-coverage %, last success/error, retry-after, review.
* GET /api/admin/export/audience.csv?days= — summary block (visitors, returning,
accounts, feedback, shares) + a blank line + the daily visits/opens series;
range applies to audience, sources is a snapshot.
* source_health now also returns feed_url/homepage. Small download links on the
Sources + Audience tabs.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: a paused/retired source with a future retry_after_at shouldn't nag
'rate-limited for 12h+' — it's intentionally out of polling. Scope long_rest to
active (matching the other operational items). Test: paused/retired rate-limited
sources stay quiet.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex — make the Overview strip diagnostic without making the operator hunt
through tables. Aggregated (one calm line per condition with a count), volume-
gated, conservative thresholds:
* Stale: active+visible source, last success > 10 days ago (warn).
* High rejection: >=20 ingested, acceptance < 25% (info).
* High duplicate: >=10 accepted, accepted-dup > 50% (info).
* Thin images: >=10 served, per-source image coverage < 25% (info).
* Long rate-limit: retry_after_at more than 12h out (info).
source_health gains a per-source images count + image_coverage. _attention takes
an optional now (for tests). Existing site-wide items (global image coverage,
thin brief, unread feedback) unchanged.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: the Next poll column computed only the streak-backoff time, so a
rate-limited source could show an earlier Next poll than the real gate (which
also requires retry_after_at <= now). Take the later of the two in the Python
post-process so the admin table agrees with due_source_rows.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex's spec — a publisher saying "slow down" shouldn't make a feed look
broken, but repeated 429s stay visible via last_success_at / stale-source.
* Schema: sources.retry_after_at (nullable) + migration.
* feeds.parse_retry_after: delta-seconds OR HTTP-date → UTC stamp; ignores
invalid/negative/past; caps at now + MAX_BACKOFF_MINUTES.
* fetch_feed raises RateLimited (carrying the parsed time) on a 429.
* poll_source: on 429 set retry_after_at + last_error, status='rate_limited',
and do NOT increment consecutive_failures; on success clear retry_after_at;
non-429 failures unchanged.
* due_source_rows requires BOTH the streak backoff elapsed AND retry_after_at
passed (i.e. the later of the two).
* Admin: source_health returns retry_after_at; status reads
"rate-limited · rests until …" rather than "failed/resting".
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex polish note: promote/reject/re-preview now Object.assign the
server-returned candidate onto the local one — keeps status/updated_at/preview
(and any future fields) in sync, while preserving the transient UI fields
(_cat/_activate/_err). Promote uses res.candidate then loadStats().
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Bring the supervised source-candidate flow into Sources (Codex's v1 scope), so
adding feeds no longer needs the CLI.
* feeds.safe_fetch_feed: SSRF-safe fetch for UNTRUSTED (admin-pasted) URLs —
http(s) only, every redirect hop re-validated via enrich._host_is_public,
body size-capped, bounded redirects, no cookies. preview_feed gains a
`fetcher` param; the API path passes safe_fetch_feed (NOT the raw fetch_feed
used for already-vetted polling).
* API (admin-gated): GET /candidates; POST /candidates (suggest+preview, gated
before the outbound fetch, no DB conn held during network); /{id}/preview
(explicit re-preview); /{id}/promote (paused by default, returns the new
source + updated candidate); /{id}/reject. rejected stays on candidates only.
* Admin Sources tab: "Add a source" field + a candidate queue showing the
preview (pass rate, recent count, example headlines) with Promote (as paused,
or Activate immediately) / Re-preview / Reject.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: upsert_sources() wrote `active` but not `status`, so a candidate
promoted inactive (the pipeline default) became active=0 + status='active' —
the exact mirror drift Phase 1 set out to avoid (scheduler won't poll, admin UI
shows "active"). Now derive status from an explicit value or from active, mirror
active off status, and write both columns together (insert + conflict update).
Test: promote_candidate(active=False) → status='paused', active=0.
Also fix stale source_health docstring (now includes retired).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex's plan — introduce a lifecycle without a risky "change the source of
truth everywhere" moment.
* Schema: sources.status (active|paused|retired) + content_visible; migration
backfills status from active (active=1→active, else paused), content_visible=1.
* `active` is kept as a SYNCED MIRROR: status active→active=1, paused/retired→0,
so the scheduler/CLI/legacy code keep working unchanged.
* Retire stops polling but keeps articles visible (non-destructive). Hiding is a
separate, reversible lever: content_visible=0 drops a source's articles from
the public feed + brief (read AND build), behind a confirm. Personal saved/
history are untouched.
* API: /sources/{id}/status (validates, mirrors active) + /visibility, replacing
/active. source_health returns status + content_visible.
* Admin: status column (active/paused/retired + "hidden"), Retired filter,
Pause/Resume · Retire/Restore · Hide/Show actions.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: slicing the SANITIZED html with [:8000] could cut through a tag or
entity. Cap the RAW editor HTML (20k) before sanitizing instead, and have
sanitize_reply_html auto-close any still-open allowed tags so malformed input
can never leave a dangling/severed tag in message_html or the email body.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Replace the Markdown composer with a small contenteditable WYSIWYG (Codex
greenlit for this narrow, admin-only surface).
* markup.py: render_reply_html → sanitize_reply_html + reply_html_to_text.
Allowlist rebuild via stdlib HTMLParser — keeps strong/em/p/br/ul/ol/li and
span ONLY with a whitelisted font-size (13/15/18/22px); normalizes b→strong,
i→em, div→p, <font size> → safe span; drops links/images/arbitrary styles
(content kept as escaped text) and discards script/style content entirely.
* API: FeedbackReplyBody.html (raw editor HTML); endpoint sanitizes → message_html,
derives plain text → stored message + the email text/plain part. Unchanged:
multipart send, store-on-success, conn released during SMTP, mark-read, 404/400/422.
* Frontend: contenteditable editor + toolbar (Bold/Italic/Size/• List/1. List),
execCommand with styleWithCSS=false for semantic tags, font size wraps the
selection in a fixed-px span, paste intercepted as plain text. No links yet.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex's optional note: alongside the ingest-wide duplicate_rate, expose
accepted_dup_rate — of what a source got ACCEPTED, how much was a duplicate of
already-served content (accepted_total − served). Nearly free (derived from
existing counts); surfaced as a tooltip on the Dup column so the table stays
uncluttered.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: a constrained Markdown-ish composer rather than contenteditable.
* goodnews/markup.render_reply_html — escapes everything first, then introduces
only a tiny whitelist (**bold**, - bullets, #/##/### headings, paragraphs,
line breaks). No links, attributes, inline styles, or raw HTML passthrough.
* feedback_replies.message_html column (+ live migration); replies store both
the Markdown text and the rendered HTML.
* email_send.send_feedback_reply now sends multipart text/plain + text/html
(the sanitized render, wrapped in a trusted email template).
* Frontend: textarea + a small toolbar (Bold / • List / H) that inserts
Markdown; the reply thread renders the server-sanitized HTML.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex's polish note: flagging a source now opens a small inline popover for
the optional reason (consistent with the calm admin UI) instead of a native
prompt(). Clearing a flag stays immediate. Backdrop/Escape/Cancel close it;
Enter confirms. Optimistic with revert-on-failure, like the other actions.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex: validate + gather in one short DB block, send SMTP with no
connection held (~20s), then reopen to record the reply + mark read. Better
operational hygiene; no behavior change.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Reply to a reader from the admin inbox instead of a mailto. Per Codex: keep v1
plain text (no rich editor — defers the user's bold/bullets ask as a fast-follow).
* DB: feedback_replies table (feedback_id, user_id, message, sent_to, sent_at),
created on the live DB.
* email_send.send_feedback_reply: plain-text "Re: Your Upbeat Bytes feedback"
with a quoted context block, no analytics/account details.
* API: POST /api/admin/feedback/{id}/reply — admin-gated, requires the feedback
exists (404) and has a contact_email (400), trims+caps the message; sends via
SMTP and only records the reply on success (502 on send failure so the UI keeps
the draft); marks the item read. Feedback list now includes each item's replies.
* Frontend: inline composer (Send/Cancel, sending state, error keeps draft) +
reply thread under the message; Reply only shows when there's an address,
else "No reply address".
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
/api/admin/stats accepts ?days= (clamped to 7/30/90, default 30) → passed to
admin_stats, which already windows visitors, retention, funnel, sharing, daily
trend, and the top lists by that span. Frontend adds a Window picker on the
analytics tabs (Overview/Content/Audience); changing it refetches and the
windowed labels ("Visitors (Nd)", "Last N days", "Returning visitors (Nd)")
follow. Corpus totals + source health are unaffected (not time-windowed).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Turn the Sources tab into a real management console (per Codex):
* source_health now lists ALL sources (active + paused) with backing metrics:
served / accepted_total / total_articles / duplicates + acceptance & duplicate
rates + review_reason, alongside last success/attempt, next poll, failures.
* Admin endpoints (gated, 404 on missing): POST sources/{id}/active (pause/
resume) and /review (flag/clear with reason).
* Pausing only stops future polling — the feed query has no active filter, so a
paused source's accepted articles stay live.
* Frontend: metric table + Paused filter + per-row Pause/Resume & Flag/Clear
(optimistic, revert on failure). Attention 'resting' now scoped to active.
Retire/Delete intentionally deferred (distinct lifecycle state, later).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex note: raise the 404 before commit so a no-match read/delete commits
nothing. get_conn only closes (no auto-commit), so this is clean.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per audit: read-toggle and delete returned {"ok":true} even for a nonexistent
id. Return 404 when no row is affected, so the optimistic UI can distinguish a
stale/already-deleted row from a real success. (The postJSON/delJSON imports
flagged in the audit were already present — verified in source + built bundle.)
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Make the admin Feedback section a real inbox.
* DB: feedback.read_at column (schema + idempotent migration).
* API: feedback list returns read_at; POST /api/admin/feedback/{id}/read
{read} toggles it; DELETE /api/admin/feedback/{id} removes a message
(both admin-gated). admin_stats gains feedback_unread; the Attention strip
and the tab badge now count UNREAD, not total.
* Frontend: unread messages are highlighted with an accent rail + dot; an
Unread filter joins the category chips; each message has Mark read/unread
and Delete (confirm), with optimistic updates that revert on failure.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex audit:
* Unknown ?section= values now clamp to Overview, so the page never renders the
tabs with an empty body.
* Summary/image coverage counts join through articles+scores and require
accepted=1 AND duplicate_of IS NULL, so percentages stay ≤100% and honest as
rejected/duplicate rows accrue summaries over time.
* A source that's both resting and flagged now shows "⚠ resting · review"
rather than hiding the review flag behind the resting state.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Codex's remaining caveat: appNavDepth decremented on every popstate, so a
browser Back then Forward undercounted (in-page Back would jump to Highlights
early). Use the navigation's signed delta on popstate (Back -1, Forward +1,
±N for jumps) instead of a flat decrement, so the depth stays accurate through
any back/forward dance. Falls back to -1 if delta is unavailable (safe).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Per Codex audit follow-ups:
* Track in-app navigation depth (forward goto/link increments, popstate
unwinds, clamped at 0) and base the in-page Back on it instead of
history.length. A direct deep link (email/social/article) now sends the
in-page Back to Highlights rather than out of the site.
* Apply the same stale-load guard to the Today/Highlights path that feed views
have, and only scroll-to-top when the load is still current — avoids stale
error/scroll state during quick navigation.
