…se reporting Extend the limits feature so a limit can count distinct hosts instead of running frames and reconcile against an external license server, gating dispatch on real license availability rather than internal counts alone. Cuebot: - limit_record gains a counting type (FRAME/HOST), an enforcement level (ENFORCED/ADVISORY/DISABLED), soft/max thresholds and report metadata. The V48 migration adds limit_host (the license server's per-host view of who holds a token) and limit_usage (cached settled totals so the dispatch gate reads one row per limit), and dedupes/constrains layer_limit and limit_record names. - Dispatch gate: layers bound to an ENFORCED limit are excluded from dispatch when merged usage (settled totals plus procs dispatched inside the settle window) is over threshold, unless the host already holds a token -- HOST limits pack work onto holding machines instead of lighting up new ones. Reports older than int_report_ttl fail open; never-reported limits count every running proc of bound layers (fail closed). The same counting rule feeds the whiteboard usage columns. - The gate applies in every scheduling mode and at both the job-finding and frame-dispatch stages; upstream never gated BALANCED job-finding, which let fully limit-blocked jobs occupy the top ranks and starve eligible work below the cutoff. Per-limit usage is computed once per query in a materialized CTE rather than per candidate row, which benchmarked 17-45x faster on the job-finding query with unreported limits; the MATERIALIZED keyword is resolved at runtime since it requires PostgreSQL 12 (PostgreSQL 11 CTEs are always fences). - Optional license-affinity frame ordering prefers work the host can run without acquiring a new license (dispatcher.limit.affinity_ordering_enabled). - A limit can claim a frame exit status: frames failing with it auto-tag their layer to the limit (b_auto_tag) and optionally delay retries (int_delay_minutes), replacing the dispatcher.layer_delay.rules property (LimitRule/LimitRuleCache in FrameCompleteHandler). - New LOCK_LIMIT_USAGE_RECALCULATION maintenance task refreshes settled usage; the report path refreshes it synchronously. Clients: - proto/pycue: expose the new limit fields and a read-only view of per-host license holds; provider credentials stay redacted. - cuegui: limit create/edit dialogs for the new fields, license usage in the limits widget and host monitor, updated layer/attribute panels. Also ships a sample license-server reporter for Houdini/sesictrl (samples/licensing). DAO, dispatcher and service tests cover the gate in every scheduling mode, the rule cache and the admin surfaces.

- Line 424: Update AdminManagerService.reportLimitUsage to make report admission

mark_auto_limits through a GUI-thread callback so dialog updates remain

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use Locale.ROOT for the hostname normalization.
String.toLowerCase() uses the default JVM locale. In a Turkish locale, "HOSTI" lowercases to "hostı" (dotless i), while Postgres LOWER() in normHost(), GET_HOLDS and AFFINITY_ORDER_SQL produces "hosti". The stored limit_host.str_host_name key then never matches the SQL side, so external holds silently stop resolving.
normalizeHostName writes the join key, so it must match the SQL rule exactly.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Throttle failed initial cache loads.
If getFailureRules() fails, loadedOnce stays false, so each frame completion calls the synchronized refresh() and retries the database immediately. Use refreshedAtMs as the retry gate after failures.

Make report admission atomic.
AdminManagerService.reportLimitUsage reads the watermark through the unlocked LimitDaoJdbc.findLimit query. Concurrent reports can pass the interval check with the same reportedTime, then replaceExternalHolds can let the later snapshot overwrite the first.

Keep limit creation and report TTL configuration atomic.
If createLimit succeeds and limit.setReportTtl fails, Cuebot retains the new limit but this dialog reports that creation failed. A retry then reports that the limit already exists, and the limit keeps the default 900-second TTL. This is critical when the user selected no external reporter, because the limit can later become stale and stop enforcing.
Add report_ttl to the create operation and apply both values transactionally. If that is not possible, refresh the created limit and report the partial success with an action to retry only the TTL update.

Correct the exit-status validation description.
The document says that exit_status = 0 clears a rule at Lines 356-357 and 518-520. These lines instead state that 0 is rejected. Document 0 as the clear value and 1 as the invalid value.
Also applies to: 593-594

Update the exit-status validation documentation so status 0 is consistently
described as the rule-clearing value and status 1 as invalid/rejected, including
the corresponding explanations at all referenced sections.

Fail closed on malformed sesictrl records.
parse_sesictrl_json skips records with unrecognized product or usage keys. build_reports then creates empty LimitReport.hosts, which ReportUsage treats as a replacement that clears existing external holds. Track parse completeness and raise ReportError before building reports. Continue accepting explicit zero-use records and valid records for unconfigured products.

Map capture-file read errors to ReportError.
If --from-file names a missing, unreadable, or invalid-text file, open or read raises outside the ReportError handler. The script then prints a traceback and exits with an unclassified status instead of its documented operational failure behavior.
Catch file read errors here and raise ReportError with an appropriate exit code.

The dispatch-time limit gate correctly let a host already holding a HOST-limit token keep booking, but UPDATE_FRAME_STARTED still carried the legacy last-chance clause counting running frames against int_max_value, with no HOST/holder, enforcement, or staleness awareness. A HOST limit of N therefore clamped a holding host to N concurrent frames: the find query returned the frames, and every start past N was silently refused. Rebuild the re-check on the real gate: UPDATE_FRAME_STARTED now prefixes DispatchQuery's LIMIT_USAGE_CTE and embeds limitFilter for the booking host, so both steps share one counting rule. The re-check itself stays -- a batch found under headroom books frame by frame, and without it a FRAME limit would overshoot by the batch; pending procs from earlier starts in the batch are counted against later ones. Regression tests: a holding host books past max under a HOST limit, and the second start of a batch is refused once the first fills a FRAME limit.

Extend the limits feature so a limit can count distinct hosts instead of
running frames and reconcile against an external license server, gating
dispatch on real license availability rather than internal counts alone.
Cuebot:
(ENFORCED/ADVISORY/DISABLED), soft/max thresholds and report metadata.
The V48 migration adds limit_host (the license server's per-host view
of who holds a token) and limit_usage (cached settled totals so the
dispatch gate reads one row per limit), and dedupes/constrains
layer_limit and limit_record names.
dispatch when merged usage (settled totals plus procs dispatched inside
the settle window) is over threshold, unless the host already holds a
token -- HOST limits pack work onto holding machines instead of
lighting up new ones. Reports older than int_report_ttl fail open;
never-reported limits count every running proc of bound layers (fail
closed). The same counting rule feeds the whiteboard usage columns.
and frame-dispatch stages; upstream never gated BALANCED job-finding,
which let fully limit-blocked jobs occupy the top ranks and starve
eligible work below the cutoff. Per-limit usage is computed once per
query in a materialized CTE rather than per candidate row, which
benchmarked 17-45x faster on the job-finding query with unreported
limits; the MATERIALIZED keyword is resolved at runtime since it
requires PostgreSQL 12 (PostgreSQL 11 CTEs are always fences).
