Ector CAD 2025 Mineral Certified Original Tax Roll ZIP Container Inventory

Direct answer for mineral owners

Start at the official Ector CAD downloads page, preserve its displayed 2025 Mineral Certified Original Tax Roll link and exact ZIP, then record the retrieval identity, integrity result, and generic three-member central-directory metadata without opening a member. This source state is separate from Ector appraisal-roll, unpaid-balance, parameters, mass-report, and reappraisal-plan files; it proves no owner, property, tax, title, value, offer, filing, or transaction fact.

Key takeaways for mineral owners

• Preserve the Ector CAD home page, downloads page, and exact ZIP as separate evidence objects because each supports a different part of the source chain.
• One recorded complete-file retrieval contained 2,808,802 bytes and matched the stated SHA-256; a later retrieval must be recorded as a new source state if it differs.
• ZIP integrity and generic three-member central-directory facts can be recorded without extracting or reading any member.
• The publisher-displayed original-tax-roll description is not proof of a row, current balance, tax result, legal effect, ownership, title, or market value.
• Stop before member-content access, row-data access, matching, private-data review, interpretation, contact, submission, payment, tax calculation, valuation, offer analysis, or sale advice.

Original-tax-roll ZIP container boundary. This page identifies the official Ector CAD publisher and downloads-page relationship, exact 2025 Mineral Certified Original Tax Roll ZIP, one complete-file retrieval, integrity result, and generic central-directory metadata. It does not extract or read a member, expose row data, perform a lookup, match another dataset, analyze a property, calculate tax or value, interpret law, decide a penalty or interest amount, establish title or ownership, evaluate an offer, direct a filing, advise a sale, contact an office, submit anything, make a payment, or promise an outcome. MRX provides educational information and resources only and does not buy mineral rights.

The official Ector CAD downloads page displays a Mineral Certified Original Tax Roll section and links WEB_MINERAL_ORIGTAX_UPDATE-2025-10-14-10142025.ZIP. A citation-ready record should preserve that publisher-page relationship and the exact ZIP before recording container metadata.

One complete-file retrieval on 2026-08-28 returned 2,808,802 bytes and matched SHA-256 af3998459f11b6bdac91e4c5792aa428ba176deb13e84da5d797e4eaeef6a7c4. The ZIP integrity test passed. Its central directory reported three members; none was extracted or read. Those facts identify one archive container. They do not establish what a row says, whether a row is current or correct, or how a record applies to a person, account, property, tax, title, value, offer, filing, or transaction.

Preserve the publisher-to-file chain

Begin at the Ector County Appraisal District home page to preserve the official publisher surface. Then preserve the Ector CAD downloads page, which supplied the displayed source context during the recorded 2026-08-28 review.

The downloads page displayed these facts together:

• section heading: Mineral Certified Original Tax Roll;
• exact file label: WEB_MINERAL_ORIGTAX_UPDATE-2025-10-14-10142025.ZIP;
• displayed size: 2.68 MB;
• displayed creation date: 10/14/2025; and
• a publisher description that says the file covers mineral accounts with an original tax, excludes penalty or interest calculations, and includes a record layout with file totals.

Preserve the exact linked ZIP as a third evidence object. The home page supports publisher identity, the downloads page supports the displayed label and link relationship, and the ZIP supports the complete-file and permitted container observations. None substitutes for another.

The Texas Comptroller Ector County directory supplies limited official district-directory context. It does not establish the Ector downloads-page display or ZIP contents. Texas Tax Code Chapter 25 supplies current statutory provenance for appraisal-record and appraisal-roll subjects. This article does not interpret that chapter or decide whether a file or row satisfies it.

Record one complete-file identity

Keep the exact issuer, route, retrieval date, response facts, and binary identity together.

Source-control field	Recorded observation
Publisher	Ector County Appraisal District
Displayed section	Mineral Certified Original Tax Roll
Exact ZIP label	WEB_MINERAL_ORIGTAX_UPDATE-2025-10-14-10142025.ZIP
Retrieval date	2026-08-28
HTTP result	200
MIME	application/zip
Complete-file bytes	2,808,802
HTTP Last-Modified	Thu, 16 Jul 2026 21:10:15 GMT
Complete-file SHA-256	af3998459f11b6bdac91e4c5792aa428ba176deb13e84da5d797e4eaeef6a7c4
ZIP integrity test	Passed
Member-content access	Not performed

The displayed 2.68 MB is publisher-page text. The exact 2,808,802 byte count is the recorded complete-file result. The file label displays a 2025 date while the HTTP response supplied a 2026 Last-Modified field. Preserve both as separately labeled observations; do not infer why they differ or silently choose one as a content date.

The hash identifies one complete retrieval. It does not authenticate every member or row, prove completeness, establish legal effect, verify a current balance, validate tax treatment, or guarantee that a future download will be byte-identical.

Inventory three members without reading them

A ZIP central directory can report container metadata without opening a member. The permitted inspection for this record stopped at that boundary.

Generic member name	Extension	Compressed bytes	Uncompressed bytes
Web_MIN_ORIG TAX AMOUNTS.csv	.csv	106,741	526,825
Web_Mineral_Owner.csv	.csv	2,692,694	29,495,685
Record Layout_Original_Tax.xlsx	.xlsx	8,813	11,750
Central-directory total	Not applicable	2,808,248	30,034,260

The integrity test passed. No member was extracted or read. A member name, extension, date, size, compression result, or integrity result is container metadata; it does not prove a member’s fields, rows, people, accounts, properties, balances, accuracy, completeness, privacy status, currency, legal effect, or fitness for a tax, title, valuation, offer, filing, or transaction question.

Do not infer content from the three filenames

The public record ends at the ZIP boundary. Do not extract a CSV or workbook, read a header, preview a row, count records, search a name, inspect an account, display a sample, calculate a total, or transform a member.

Permitted container observation	Prohibited content action
Exact publisher, page, and ZIP routes	Opening or copying a CSV or workbook member
Complete-file bytes and SHA-256	Hashing, displaying, or summarizing a row
Generic member names and extensions	Reading a header, field, line, worksheet, cell, or formula
Compressed and uncompressed bytes	Calculating row, person, account, or property counts
Integrity result	Treating integrity as proof of row accuracy or tax status
Retrieval and Last-Modified fields	Treating the archive as unchanged on a later date

Even one header or worksheet tab is member-content access. A request for one owner, account, legal description, property, tax amount, penalty, interest, or value is row-data access. Both are outside this article.

Separate the original-tax-roll archive from adjacent Ector sources

The Ector CAD downloads page presents several separately labeled files. Preserve those source identities rather than merging them.

• The Ector CAD 2026 Certified Mineral Appraisal Roll ZIP Source-Control Record owns a different 2026 appraisal-roll ZIP, binary, display context, and one-member central directory.
• The Ector CAD 2026 Mineral Appraisal Parameters Source Index owns a separate 60-page parameters PDF and its bounded page map.
• The Ector CAD 2026 Mass Appraisal Report Mineral Section Page Crosswalk owns a separate 45-page report and mineral-section locators.
• The Ector CAD 2027-2028 Reappraisal Plan Oil and Gas Section Source Locator owns a separate 120-page plan and bounded oil-and-gas page path.
• This page owns only the displayed 2025 mineral original-tax-roll link, exact ZIP container, complete-file identity, integrity result, and generic three-member central-directory metadata.

The downloads page also displays a separately labeled unpaid-balance file with a different filename, date, description, and link target. That file is not evidence for this article. A publisher label does not authorize combining an appraisal roll, original-tax roll, unpaid-balance file, PDF statement, search result, or property record into one conclusion.

Preserve source drift instead of overwriting it

The publisher may replace the ZIP while retaining a similar section heading, change the link target, revise the filename, or publish another year. Never overwrite the earlier observation silently.

For each later retrieval, preserve:

1. Official home-page and downloads-page URLs.
2. Displayed section heading, exact file label, displayed size, creation date, description, and link relationship.
3. Exact final ZIP URL after redirects.
4. Retrieval date, time, time zone, and method.
5. HTTP status, MIME, Content-Length if supplied, and Last-Modified field if supplied.
6. Complete-file byte count and SHA-256.
7. Integrity result and generic central-directory member count, names, extensions, compressed bytes, and uncompressed bytes.
8. Explicit confirmation that member-content and row-data access were not performed.

If any item differs, preserve a new source state. Do not merge member lists, choose a controlling copy, infer the cause of a change, or treat an earlier hash as proof about a later file.

Use a citation-ready answer sequence

A bounded answer about the Ector CAD 2025 mineral original tax roll should keep each claim next to its exact official source:

1. Name Ector County Appraisal District as the publisher.
2. Cite the official downloads page for the displayed section heading, file label, displayed size, creation date, description, and link relationship.
3. Cite the exact ZIP for the complete-file retrieval and permitted container observations.
4. Preserve the retrieval date, HTTP result, MIME, complete-file bytes, Last-Modified field, SHA-256, and integrity result.
5. Identify the three generic central-directory members only as container metadata.
6. State beside the inventory that no member was extracted or read and no row claim is made.
7. Keep the 2026 mineral appraisal-roll ZIP, unpaid-balance file, parameters PDF, mass report, reappraisal plan, property-search surfaces, and other-county archives outside this ZIP’s evidence lane.

That sequence improves traceability and answer usefulness. It does not guarantee search ranking, indexing, LLM retrieval, citation, traffic, leads, or revenue.

Stop when the question depends on a member or row

This container-inventory job is complete when the publisher relationship, exact file identity, retrieval facts, integrity result, generic central-directory metadata, and limitations are preserved. Stop before:

• extracting, opening, reading, searching, indexing, transforming, previewing, sampling, copying, displaying, reproducing, summarizing, matching, enriching, or interpreting a member;
• exposing or inferring a person, owner, name, address, account, legal description, property, acreage, lease, operator, well, tax amount, penalty, interest, appraisal, exemption, protest, ownership, title, private data, value, offer, filing, or transaction fact;
• interpreting a statute, certified label, original-tax label, publisher description, file, field, worksheet, cell, or row;
• deciding district compliance, tax treatment, current balance, appraisal correctness, protest merits, filing strategy, ownership, title, market value, offer quality, sale price, or whether an owner should sell;
• contacting an office, submitting a record, making a payment, negotiating, or representing an owner; or
• promising an outcome.

A later authorized workflow would need its own legal basis, access controls, privacy controls, retention rules, source dates, reviewer role, and professional limitations. This public article supplies none of those permissions. Its narrow deliverable is a citation-ready inventory of one official Ector CAD ZIP container and what that container record does not establish.

Frequently asked questions

Where does Ector CAD link the 2025 mineral original-tax-roll ZIP?

The official Ector CAD downloads page displays a Mineral Certified Original Tax Roll section and links the exact ZIP. Preserve the home page, downloads-page URL, and direct ZIP URL separately because they support different parts of the source chain.

What did the recorded complete-file retrieval establish?

The recorded 2026-08-28 retrieval returned an application/zip file with 2,808,802 bytes, the stated SHA-256, the recorded Last-Modified field, and a passing archive-integrity result. Those facts identify one retrieved container only.

How many members did the ZIP central directory report?

It reported three members with a combined 30,034,260 uncompressed bytes. No member was extracted or read, so this article makes no claim about fields, rows, people, accounts, properties, balances, or tax results.

Is this the same artifact as the certified mineral appraisal roll or unpaid-balance file?

No. The Ector CAD downloads page presents those as separately labeled sections with different file labels and link targets. This page preserves only the named 2025 mineral original-tax-roll ZIP.

What if the downloads-page link or ZIP changes?

Preserve the later page relationship, exact URL, retrieval time, MIME type, bytes, Last-Modified field, hash, integrity result, and generic central-directory metadata as a new source state. Do not overwrite or merge versions silently.
