Thanks for picking this up.

Since I'm not a native Greek speaker and don't know any other, I asked Claude on this one. It's feedback:

Likely wrong

1. common.filters.completedAt is "Ολοκληρώθηκε Στ(η/ις)". The (η/ις) is a literal "either form" placeholder that would show in the UI. The sibling queuedAt uses "Σε Ουρά Στις", so "Ολοκληρώθηκε Στις" fits.
2. dag.versions.truncated.description says "…το πλήθος είναι μια κατώτερη δέσμευση" for "the count is a lower bound". "Δέσμευση" means commitment or binding, so this is a mistranslation. "κάτω όριο" or "κατώτατο όριο" is what I'd expect.

Unsure, please look at these

3. "Drain" translated as Εξάντληση (components.pausedDag.drain, dags.schedulingActions.*, schedulingState.draining, the banner and tooltips). Εξάντληση means exhaustion or depletion. In infrastructure terms "drain" is usually Αποστράγγιση, or a descriptive phrase like "Ολοκλήρωση και παύση". I can't tell if it reads naturally to a Greek ops reader. [Ed: I suspect "depletion" is the most correct form".]
4. common.breadcrumb is "Δυναμική Διαδρομή Πλοήγησης". "Δυναμική" means "dynamic", and English only says "Breadcrumb". Plain "Διαδρομή πλοήγησης" seems safer, unless this was deliberate.
5. "Callback" left in English (dag.versions.categories.callback, dag.calendar.backfill is "Backfill", which is fine). el.md doesn't list Callback as a kept-English term, and no existing Greek string uses it. Επανάκληση is the Greek word, but keeping it in English is plausible.
6. "serialized schema" translated as σειριοποιημένο σχήμα (dag.versions.summary_*). The global rules keep Schema in English, and the el guideline doesn't override that. σειριοποιημένο is also my guess at a rare term. The existing admin.url_schema uses Σχήμα, which is probably a mistranslation of
   "URL scheme" but isn't part of this PR.
7. "Operation" translated as Λειτουργία (dag.versions.columns.operation). Existing el/dag.json uses Λειτουργία for "Mode", so the same word now means two things. The versions.operations.* states are added, changed and removed.
8. Εμφανίσεις for "Occurrences" (versions.columns.occurrences). It's valid Greek, but it can also read as "views" or "impressions".
9. στιγμιότυπο for "instance" (dashboard.health.instances.title_*). This is the standard CS term, but the locale has no other use of it. The locale already uses "Εκτέλεση Εργασίας" for task instance, so this is only a terminology-collision check.
10. "Ομάδα" for Team (dashboard.degradedHint.triggerer, common.teams.*). It matches the existing team key, but "ομάδες" in the triggerer hint could be misread as task groups (Ομάδα Εργασιών).
11. Word order and wording
    • browse.xcom.entry_* is "XCom Εγγραφή". Greek would normally say "Εγγραφή XCom".
    • backfill.partitionsAffected_* uses lowercase backfill inside the sentence, while the glossary capitalizes Backfill.
    • pausedDag.drainDescription and unpauseDescription start a sentence with "Backfills σε παύση…" without the article. "Τα Backfills σε παύση…" reads better.

Any truth to these?

1. Στη is when singular form follows and Στις is when plural form follows. When you are referring to 1 o'clock in the morning you need to use singular Στη while when it's 1 o'clock in the afternoon, it's plural because in 24-hour format it's equal to 13:00. Depending on the time, you need to use one or the other. For example, it's like having 1 instance(s) or ending up with 1 instances. I don't know which is worse to look at.

2. I struggled with this one. The english version is "Changes at paths not shown were dropped to stay within the limit, so the count is a lower bound.". Doesn't it mean that the count ends up being a lower number?

3. Εξάντληση is correct. It also means to take bit by bit out of something until there is none left. Αποστράγγιση is used only for liquids but it makes sense here because it's the exact translation of the word drain. I'll use that.

4. Plain "Διαδρομή πλοήγησης" seems safer

   Indeed and I'm not 100% sure that all navigations are dynamic. So I'll remove it.

5. Other languages such as French and German have also kept is as Callback, so let's leave it as it is.

6. If it's in the rules, then let's keep Schema as it is in English.

7. Same word, multiple meanings but let me change one of them.

8. Nothing to do here

9. Nothing to do here

10. Nothing to do here

11. backfill.partitionsAffected_* uses lowercase backfill inside the sentence, while the glossary capitalizes Backfill.

    It's lowercase in english but I'll change it.

@ashb Thanks for the review! I've addressed all points except number 1 which I left as it is.

For number 2, I couldn't translate the exact words because it wouldn't make sense, so the translation now is based on the meaning and it's along the lines of "so the count is a lower limit number".
