These accepted any JSON type on both POST and PATCH, silently mangled
into Python repr() strings at save time (a dict became the literal text
"{'a': 1}", unparseable as JSON) - and the immediate response echoed the
raw pre-save value, while a later GET returned the mangled one, an
internally inconsistent API.
Added validate_string_fields(), rejecting non-string values with 400
before they reach save(), matching #005's approach for tags. Verified live
and with new tests.

make_room_for() read usage before any write lock was held, so concurrent
requests could each read stale data and both conclude "this fits" -
confirmed reproducible (measured 616 bytes over a 1551-byte quota with 5
truly concurrent posts).
Fix: force SQLite to acquire its write lock immediately via a no-op UPDATE
on the user's UserProfile row, before reading `used`, wrapped in
transaction.atomic() through the subsequent Artifact.objects.create() so
the lock is held across the whole eviction+insert sequence. Added a 20s
DB timeout as headroom for legitimate contention.
Deliberately no retry/backoff logic - this project's actual load (a
low-volume self-hosted tool) doesn't need it, and SQLite has no row-level
locking regardless, so quota-affecting writes serialize globally either
way. Did fix a real bug found while verifying this: exception handling
around artifact creation only caught QuotaExceeded, so a genuine lock
timeout left the just-written file orphaned on disk - both call sites now
clean up on any exception.
Verified live against the real dev instance (twice, with 5 truly
simultaneous posts against a tight quota) rather than via an automated
test - Django's in-memory shared-cache test database uses a different,
non-retryable SQLite locking model that fails for reasons unrelated to
this fix's correctness.

Confirms all five are live on the local dev instance without a restart
(autoreload picked them up), and suggests where to probe next - boundary
cases on the new length/content-shape validation, other wrong-typed PATCH
fields beyond tags, and eviction race conditions #006 doesn't cover.

- #006 (high, data loss): make_room_for() no longer deletes unkept
artifacts on a doomed request - checks whether eviction can possibly
succeed before deleting anything. Also fixed a related latent bug found
while testing: the function returned evicted Artifact objects after
calling .delete() on them, so their .id was always None (Django clears
pk on delete); now returns ids captured beforehand.
- #003: added server-side field-length validation (source/title/
source_name/source_id/theme) on POST and PATCH, matching the model's
own max_length limits, which were previously unenforced on the ingest
path entirely.
- #004: ported daybook_post.py's content-shape validation
(html_fragment/html_full/deck/markdown) to the server, closing the gap
for any client that doesn't go through the helper script.
- #005: PATCH now rejects wrong-typed `tags` (previously silently wiped
existing tags) and rejects immutable fields (content/source/kind/day)
with 400 instead of silently no-op'ing them.
- #002: deleted the misleading skills/daybook-posting/.env.example (a
zero-dependency script that never reads .env files) and clarified
SKILL.md/docs/llm_posting_helper.md that these must be real
process/shell env vars.
Adds tests/unit/ for storage-layer tests. 46 tests passing (was 25).

The app-side fix (CSRF_TRUSTED_ORIGINS, SECURE_PROXY_SSL_HEADER in
settings.py) was already committed as d458cd3 after the first Cloud-VM-1
deployment hit "CSRF verification failed" on login behind Apache. This
finishes the rest of that issue's checklist: documents
DJANGO_CSRF_TRUSTED_ORIGINS in deploy/env.example, adds the required
X-Forwarded-Proto header to the Apache/Caddy examples in
cloud_agent_deploy.md (plus a checklist item that verifies via an actual
login, not just an unauthenticated capabilities curl), and adds the same
proxy-agnostic guidance to docs/deployment.md.
Also introduces issues/, a tracked one-file-per-issue log for the project
going forward.
