Ector CAD 2026 Certified Mineral Appraisal Roll ZIP Source-Control Record

Direct answer for mineral owners

Start at the official Ector CAD downloads page, preserve the exact displayed 2026 certified mineral appraisal roll ZIP link, retrieval time, MIME, bytes, Last-Modified field, and complete-file SHA-256, then record only the integrity result and generic one-member central-directory metadata. Do not extract or read the member, expose row data, perform matching, or use the archive to decide an appraisal, tax, title, value, offer, or sale question.

Key takeaways for mineral owners

• Preserve the official Ector CAD home page, downloads page, and exact ZIP as separate evidence objects because each proves a different source relationship.
• One recorded complete-file retrieval contained 5,944,285 bytes and matched the stated SHA-256; a later retrieval must be recorded as a new source state if it differs.
• The ZIP integrity test and generic central-directory inventory can be recorded without extracting or reading the single CSV member.
• A certified label and filename do not establish row accuracy, completeness, legal effect, property application, appraisal correctness, tax treatment, title, or market value.
• Stop before member-content access, row-data access, matching, private-data review, interpretation, contact, submission, valuation, offer analysis, or sale advice.

Certified-roll ZIP source-control boundary. This page identifies the official Ector CAD publisher and downloads-page relationship, exact 2026 certified mineral appraisal roll ZIP, one complete-file retrieval, integrity result, and generic central-directory metadata. It does not extract or read the member, expose row data, perform a lookup, match another dataset, analyze a property, interpret law, judge an appraisal, calculate tax or value, establish title or ownership, evaluate an offer, advise a sale, contact an office, submit anything, or promise an outcome. MRX provides educational information and resources only and does not buy mineral rights.

The official Ector CAD downloads page currently displays a Certified Mineral Appraisal Roll section and links a file labeled 2026_CERTIFIED_MIN_APPRAISAL_ROLL-7222026.ZIP. For a citation-ready source record, preserve the publisher page and exact linked archive before recording any container metadata.

One complete-file retrieval on 2026-08-28 returned 5,944,285 bytes and matched SHA-256 1a756063972e7008dc0b33b8fe9260f73dc576a1dfe46b0fdcc12490922b17c8. A ZIP integrity test passed. Central-directory inspection reported one CSV member; the member was not extracted or read. Those facts identify one archive container. They do not establish what a row says, whether a row is correct, or how any record applies to a person or property.

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 current display context during the recorded 2026-08-28 review.

The downloads page displayed these source facts together:

• heading: Certified Mineral Appraisal Roll;
• exact file label: 2026_CERTIFIED_MIN_APPRAISAL_ROLL-7222026.ZIP;
• displayed size: 5.67 MB;
• displayed creation date: 7/22/2026; and
• publisher description: Fixed format text file for all Mineral accounts.

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 direct ZIP supports the complete-file and container observations. None is a substitute for the others.

The Texas Comptroller Ector County directory supplies limited official district-directory context. It does not establish the Ector downloads-page display or the 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

Use a retrieval record that keeps the exact issuer, route, date, response facts, and binary identity together.

Source-control field	Recorded observation
Publisher	Ector County Appraisal District
Displayed section	Certified Mineral Appraisal Roll
Exact ZIP label	2026_CERTIFIED_MIN_APPRAISAL_ROLL-7222026.ZIP
Retrieval date	2026-08-28
HTTP result	200
MIME	application/zip
Complete-file bytes	5,944,285
HTTP Last-Modified	Wed, 22 Jul 2026 15:07:18 GMT
Complete-file SHA-256	1a756063972e7008dc0b33b8fe9260f73dc576a1dfe46b0fdcc12490922b17c8
ZIP integrity test	Passed
Member-content access	Not performed

The displayed 5.67 MB is publisher-page text. The exact 5,944,285 byte count is the recorded complete-file result. Keep those facts labeled rather than forcing them into one normalized number.

The hash identifies one complete retrieval. It does not authenticate every row, prove completeness, establish legal effect, validate an appraisal, or guarantee that a future download will be byte-identical.

Inventory the container without reading the member

An archive central directory can report container metadata without opening the member. The permitted inspection for this record stopped at that boundary.

Archive observation	Recorded result
Non-directory members	1
Generic member name	2026_Certified_MIN_Appraisal_Roll.csv
Generic extension	.csv
Member compressed bytes	5,944,041
Member uncompressed bytes	48,617,973
Archive integrity	Passed
Member extraction	Not performed
Member-content access	Not performed

A member name and extension are container metadata. They do not prove the member’s fields, row count, row accuracy, completeness, currency, legal effect, privacy status, or fitness for a property, tax, title, valuation, offer, or transaction question.

Do not open, preview, or sample the CSV

The public record ends at the archive boundary. Do not extract the CSV, open it in a spreadsheet, read a header, preview a row, count records, search a name, inspect an account, display a sample, create a summary, or transform the member to another format.

Permitted source-control fact	Prohibited content action
Exact publisher and ZIP URLs	Opening or copying the CSV member
Complete-file bytes and SHA-256	Hashing, displaying, or summarizing a row
Generic member name and extension	Reading a header, field, line, or cell
Compressed and uncompressed bytes	Calculating row counts or content statistics
Integrity result	Treating integrity as proof of row accuracy
Retrieval date and Last-Modified field	Treating the archive as unchanged on a later date

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

Keep the three Ector sources separate

The current Ector corpus now has three adjacent but noninterchangeable official documents:

• The Ector CAD 2026 Mineral Appraisal Parameters Source Index owns the separate 60-page parameters PDF, its contents map, source-year roles, and printed parameter-page boundary.
• The Ector CAD 2026 Mass Appraisal Report Mineral Section Page Crosswalk owns the separate 45-page mass report, physical page 10 locator, and physical pages 42 through 45 mineral-section boundary.
• This page owns the downloads-page relationship, exact certified-roll ZIP container, complete-file retrieval identity, integrity result, and generic one-member central-directory metadata.

Do not cite one source for a statement found only in another. Do not combine a parameters statement, mass-report section, or archive filename into a property conclusion. Topic overlap does not erase separate file identities or source roles.

The Culberson certified mineral-roll ZIP source-control record and the Dimmit archive inventory concern different counties, publishers, URLs, binaries, and member inventories. They supply process adjacency only; they are not evidence about the Ector archive.

Preserve source drift instead of overwriting it

The publisher may replace the ZIP while keeping a similar label, 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, and description.
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, and compressed 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 an internal change, or treat an earlier hash as proof about the later file.

Use a citation-ready answer sequence

A bounded answer about the Ector CAD 2026 certified mineral appraisal roll should keep the claim and exact official source adjacent:

1. Name Ector County Appraisal District as the publisher.
2. Cite the official downloads page for the displayed Certified Mineral Appraisal Roll section, exact file label, displayed size, displayed creation date, description, and link relationship.
3. Cite the exact ZIP for the complete-file retrieval and permitted container observations.
4. Preserve retrieval date, HTTP status, MIME, complete-file bytes, Last-Modified field, SHA-256, and integrity result.
5. Identify the one generic central-directory member only as container metadata.
6. State next to the inventory that the member was not extracted or read and that no row claim is made.
7. Keep the parameters PDF, mass report, property-search surfaces, and other county archives outside the Ector ZIP evidence lane.

That sequence improves source 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 row

This source-control 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, sampling, copying, displaying, reproducing, summarizing, matching, enriching, or interpreting the member;
• exposing or inferring a person, owner, name, address, account, legal description, property, acreage, lease, operator, well, appraisal amount, tax amount, exemption, protest, ownership, title, private data, value, offer, or transaction fact;
• interpreting a statute, certified label, publisher description, file, field, or row;
• deciding district compliance, appraisal correctness, tax treatment, protest merits, 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 record of one official Ector CAD archive container and what that container record does not establish.

Frequently asked questions

Where does Ector CAD link the 2026 certified mineral appraisal roll ZIP?

The official Ector CAD downloads page displays a Certified Mineral Appraisal Roll section and links the exact 2026 ZIP. Preserve the home page, downloads-page URL, and direct ZIP URL as separate source objects.

What did the recorded complete-file retrieval establish?

The recorded 2026-08-28 retrieval returned an application/zip file with 5,944,285 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 archive members did the central directory report?

The central directory reported one CSV member with 5,944,041 compressed bytes and 48,617,973 uncompressed bytes. The member was not extracted or read, so this article makes no row or content claim.

Does the certified label prove that a mineral record is correct?

No. The label is preserved as publisher metadata. This source-control record does not test a row, prove completeness, decide legal effect, validate an appraisal, calculate tax, establish title, or determine market value.

What if a future ZIP or downloads-page link changes?

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