feat(daily-notes): folder/format env settings, config-read retry, and default-on SYNC_CONFIGS

[aliasunder]

Closes #427.

Stacked on #428 (feat(security): block hidden paths in all vault operations), now merged — this PR targets main and its diff shows only the daily-notes work.

What this fixes

Three gaps from #427:

1. Daily-notes settings were unreachable on standard remote deployments. SYNC_CONFIGS was supported by the init chain but passed through by no shipped compose file and documented nowhere, so .obsidian/daily-notes.json never reached the server — daily notes worked only when the vault's settings happened to match the defaults.
2. A failed config read was cached for the process lifetime. On a fresh remote deploy the server boots before the initial sync delivers .obsidian/, and server.ts reads the config at startup — so the boot race was guaranteed, and the defaults stayed locked in until a restart.
3. Periodic Notes users had no way to point the server at the right folder — the core daily-notes.json file (which vault-cortex reads) isn't updated by the Periodic Notes plugin.

Changes

• DAILY_NOTES_FOLDER / DAILY_NOTES_FORMAT env settings with per-field precedence: env setting → .obsidian/daily-notes.json → the fallbacks (Daily Notes, YYYY-MM-DD). The format keeps Obsidian's moment tokens; validation at startup is structural fail-fast (probe-render a fixed date; reject traversal, leading or trailing separators, and empty renders) — unknown tokens are not rejected — tokens without a Luxon mapping fall into Luxon's own token grammar and may render differently than Obsidian, so only structurally unsafe results are blocked. When both fields are overridden, the config file is not read at all. The env settings are threaded as params (DailyNotesEnvSettings) from VaultConfig through vault_get_daily_note, the daily-review prompt, and the startup read — no module-level setter.
• Config caches hold only successful reads. daily-notes.ts and task-format-config.ts (same race class) no longer cache the missing/malformed-file fallback — it's recomputed per call, so a config file delivered by sync after boot is picked up without a restart. Cost while the file is absent: one failed readFile per call. Once a read succeeds it's cached for the process lifetime, as before. The broken-link forward-reference exclusion no longer relies on a startup-seeded copy: getOutgoingLinks and brokenLinkCount take the daily notes folder as a parameter, resolved fresh per call by their callers, so a config file that arrives after boot corrects the annotation and count without a restart.
• SYNC_CONFIGS defaults to core-plugin-data,community-plugin-data — the two categories the server reads: daily-notes settings, and community plugin settings (the Tasks plugin's format, which vault_update_task's write-format detection uses). Applied in the remote compose files, the init script (so plain docker run, where compose interpolation doesn't apply, behaves the same), and CI deploys (optional repo-variable passthrough, PROTECTED_PATHS-style). Pulling a category is a no-op unless the desktop pushes it via Settings → Sync → "Vault configuration sync" — those per-device toggles are the real gate. Disabling is the explicit none sentinel, which actively clears the category list (ob sync-config --configs "") rather than skipping — on a persistent config volume, skipping would leave a previously enabled category on across boots. Community plugin settings can carry API keys for plugins that use external services; feat(security): block hidden paths in all vault operations #428 blocks all tool reads of .obsidian/ and the server opens only the two config files it needs, so synced settings otherwise sit unread in the config volume (noted in the deploy docs).
• moment-format.ts extracted from daily-notes.ts as a pure zero-import module so config.ts can validate formats without pulling in filesystem/logger deps. Token conversion runs only outside [literal] escapes, so literal text containing token letters ("[Week A]") is preserved verbatim — the previous convert-after-quoting order corrupted it (pre-existing, surfaced by review).
• Docs: README Configuration rows + a "Daily notes" section (precedence, remote sync mechanics, Periodic Notes guidance); deploy/remote README "Daily notes" section + config table rows; DEPLOY.md CI variables; ARCHITECTURE.md resolution chain; .env.example × 3; synced CLI env blocks.
• DOCKERHUB generator: the new table rows pushed the generated README past Docker Hub's 25000-byte cap (it was at 24785), so the generator now collapses markdown table padding (renders identically) and drops H3 subsections inside compact sections instead of emitting an empty heading. Output is now 18873 bytes.

Behavior change

Remote deployments that previously left SYNC_CONFIGS unset now sync the core-plugin-data and community-plugin-data categories by default. This only has an effect when the desktop pushes those categories; set SYNC_CONFIGS=none to keep config sync fully off.

Tests

• Precedence matrix (folder-only / format-only / both-vs-conflicting-file / both-no-file / folder-only-no-file), ENOENT-retry and malformed-then-fixed for both config readers, success-cache behavior pinned, getDailyNotePath exact path with overrides.
• loadConfig: defaults, empty/whitespace-as-unset, raw moment string preserved, nested YYYY/MM/DD accepted, exact failure messages for traversal (raw and rendered), leading and trailing separators (raw and rendered), and empty render.
• Exact-form drift pin: SYNC_CONFIGS: ${SYNC_CONFIGS:-core-plugin-data,community-plugin-data} in both remote compose files; existing compose ↔ .env.example ↔ CLI-block consistency tests cover the new vars.
• Mutation-verified: reverting the cache fix makes exactly the three retry tests fail; all four SYNC_CONFIGS states (unset / empty / none / custom) exercised against the init script's branch logic with stubbed commands under sh -e.
• npm run lint clean, both builds green, full suite 2527 tests passing.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🟡 Moderate · up to 45260

The PR adds configurable daily-note behavior and retryable configuration reads, but escaped format literals can still change, search may retain the wrong daily-notes folder after sync, and task-format settings can change unexpectedly when switching vaults. These correctness issues should be fixed before merging.

Add Daily notes to the remote README Contents line
Low severity · correctness · high confidence

deploy/remote/README.md:6 — beyond the diff's line ranges, in code the changes touch or depend on.

The new ## Daily notes section was added between File Tools and Configuration, but the Contents line at the top of the file still lists [File Tools](#file-tools) · [Config](#configuration) with no Daily notes entry. A reader navigating by the Contents cannot find the new section, and the root README's Contents was updated for the same section — the sibling doc was missed.

Failure scenario: A user opens deploy/remote/README.md, scans the Contents line for the daily-notes configuration guidance described in the PR, and finds no entry — the section exists but is unreachable from the document's own navigation.

Suggested fix

Add `[Daily notes](#daily-notes)` to the Contents line between File Tools and Config, matching the root README's update.

[aliasunder]

Add Daily notes to the remote README Contents line — fixed in 1c76288: deploy/remote/README.md's Contents line now includes Daily Notes between File Tools and Config, matching the root README's Contents update.

Initialize behavior reveals empty SYNC_CONFIGS value as the default in init-setup.sh
Medium severity · correctness · high confidence

rootfs/s6-overlay/init-setup.sh:92 — beyond the diff's line ranges, in code the changes touch or depend on.

When SYNC_CONFIGS is explicitly set to an empty string (via —env-file with a blank value), the script supplies neither the default core-plugin-data nor the clearing none behavior. Instead, it calls apply_sync_config —configs « which returns early, leaving previously enabled categories active across boots. The compose files use ${-_configs:-core-plugin-data} which inserts the default only for unset, not empty, so a docker run —env-file with SYNC_CfGS= behaves differently from the compose path the PR aims to unify.

Failure scenario: Plain docker run —env-file .env where .env contains SYNC_CONFIGS= (empty) on a persistent config volume where core-plugin-data was previously enabled. The script skips the default and logs an early return from the empty-passing, leaving the old categories active. Similarly for a fresh volume no categories are configured at all.

Suggested fix

Replace the else branch test ‘test `[ -z “$SYNC_CONFIGS” ] || expandSyncProps` to ensure empty string also resolves `core-plugin-data`. For example: `local value=“${SYNC_CONFIGS-core-plugin-data}”; sync else … | configs "$value"`.

Docker Hub configuration table includes DAILY_NOTES_FOLDER/FORMAT but omits SYNC_CONFIGS row
Medium severity · correctness · medium confidence

scripts/generate-dockerhub-readme.ts:170 — beyond the diff's line ranges, in code the changes touch or depend on.

The PR newly lists DAILY_NOTES_FOLDER and DAILY_NOTES_FORMAT on the Docker Hub config table, but SYNC_CONFIGS is not in any config table—it only report says the 'Daily notes' section which is entirely omitted by the generator. Obsidian Sync users reading only the Docker Hub page cannot learn that they must enable SYNC_CONFIGS for config file sync, exactly the bug this PR fixes. The SYNC_CONFIGS variable column URL would link to the remote guide, as the existing missing-message row does for the already missing-mess SYNC_COMMUNITY_DATA.

Failure scenario: A remote-only Docker Hub reader sees critical_FOLDER defaults to › from obsidian config › and is not aware that .obsidian.yml won't reach the server if SYNC_CONFIGS is disabled (or if desktop sync is off). The daily note path resolves to the default / and the tool reports the real daily note missing.

Suggested fix

Add a `SYNC_CONFIGS` row to the README table (outside the remote-only note) so the generator includes it in DOCKERHUB.md, e.g.: `| SYNC_CONFIGS | remote-only | core-plugin-data | Obsidian categories synced; ‘none’ disables`.

Clarify that local mode reads daily notes config directly from the bind-mounted vault
Low severity · correctness · high confidence

deploy/local/.env.example:47 — beyond the diff's line ranges, in code the changes touch or depend on.

The .env.example files for both modes include comment for DAILY_NOTES_FOLDER/DAILY_NOTES_FORMAT but the remote variant references SYNC_CONFIGS while the local variant does not. A local user reading the comment sees default: read from the vault's .obsidian/daily-notes.json but might wonder if additional steps are needed (like enabling SYNC_CONFIGS). Clarifying that the file is read directly from the vault's instead of needing sync would prevent confusion.

Failure scenario: A local user reads synctonically .env.example, sees the comment about sync through SYNC_CONFIGS and attempts to find and set SYNC_CONFIGS locally, or unnecessarily re-sets DAILY_NOTES_FOLDER inside a ` own compose file. Server works correctly, but documentation misleads.

Suggested fix

Add a brief statement after the line: ‘(read directly from your bind-mounted vault — no additional setup needed)’.

[aliasunder]

Addressing the three PR-level findings:

Remote README Contents line missing Daily notes — already present. Line 18's Contents line includes [Daily Notes](#daily-notes) between File Tools and Config; it was added alongside the section in an earlier commit on this branch. Stale against the current head.

Empty SYNC_CONFIGS in the init script — the premise is inverted. POSIX ${VAR:-default} substitutes the default for unset AND empty values; only the colon-less ${VAR-default} form is unset-only. Verified empirically: the else branch's expansion with SYNC_CONFIGS set to the empty string prints core-plugin-data,community-plugin-data, matching the compose path exactly. Also note the cited path rootfs/s6-overlay/init-setup.sh does not exist in this repo; the script is rootfs/etc/s6-overlay/scripts/init-setup-vault. Same refutation posted on the inline thread making this claim.

Local .env.example SYNC_CONFIGS clarification — declining. The local template never mentions SYNC_CONFIGS (that reference exists only in the remote variant, where it is accurate), so there is no thread for a local reader to pull. The local comment already states the config is read from the vault's .obsidian/daily-notes.json, which for a bind-mounted vault is the direct read. Keeping the env templates lean was a deliberate pass on this PR.

Test the daily-notes config wiring in handlers and prompts
Medium severity · tests · medium confidence

The new per-call daily-notes config resolution is glue with no direct test: the config reader (daily-notes.ts) and the query layer (getOutgoingLinks/brokenLinkCount) are tested independently, but nothing verifies that the tool handler and the two prompts actually pass the resolved values through. A regression that drops the envSettings argument or the dailyNotesFolder parameter changes behavior with no failing test — the search-index tests pass the folder explicitly, so they would still pass if a caller silently stopped supplying it.

Failure scenario: DAILY_NOTES_FOLDER=Journal is set and a refactor removes the envSettings argument from the getDailyNote call in daily-note-tools.ts. vault_get_daily_note silently ignores the override, resolves Daily Notes/today.md instead of Journal/today.md, and reports the existing note as missing — no test fails because the handler wiring is untested. The same gap applies to the daily-review/vault-orientation prompts: if the readDailyNotesConfig result stops being passed to getOutgoingLinks/brokenLinkCount, daily-note forward refs in a custom folder are reported as broken links with no failing test.

Suggested fix

Add a handler-level test asserting vault_get_daily_note with DAILY_NOTES_FOLDER set resolves the override path (not the file/default), and a daily-review prompt test with a custom daily-notes folder where a future-date forward-ref link must be excluded from the broken-link summary.
