Tempora's methodology, calibration code, natal chart records, lift table and forward-call receipts are all published under Creative Commons Attribution 4.0. A researcher with access to the public files can rerun the calibration, extend it to new charts, replicate at stricter thresholds, and publish their own work with attribution. Internal workings stay private. This piece walks through what the license covers, what it does not, how to cite Tempora, and the invitation to build on the framework.
Creative Commons Attribution 4.0 International is the most permissive Creative Commons license that still requires attribution. A reader can share the licensed material, adapt it, remix it, build commercially on it, and redistribute the result. The single condition is that the reader gives appropriate credit to the original author, links to the license, and indicates if changes were made.
The license does not require the reader to publish derivative work under the same license. It does not require the reader to share the derivative back to the original author. It does not constrain the commercial use of the derivative. The only constraint is attribution.
Tempora has chosen this license because the brand position rests on openness as a research property. A more restrictive license (CC-BY-NC for non-commercial only, or CC-BY-SA for share-alike) would create friction for researchers, journalists and other practitioners who want to build on the methodology in their own commercial or academic work. The choice was made deliberately and the LICENSE file in the public repository is the canonical record of it.
The full license text lives at creativecommons.org slash licenses slash by slash 4.0 slash legalcode. The plain-language summary is at the same path with /summary appended. The Tempora LICENSE.md file in the repository is a short pointer with the firm-specific attribution format and the public-versus-private boundary.
The CC-BY 4.0 license covers eight categories of material. Each is published in full at the canonical Tempora URL or in the public source repository.
| Asset | Path | Purpose |
|---|---|---|
| Methodology articles | tempora.ltd/findings, /research, /article_NNN_* | The published technique articles, case studies, and forward calls (49+ articles as of May 2026) |
| Research notes | tempora.ltd/Tempora_Research_Note_NNN_* | Numbered research notes 001 to 009 covering introduction, India, Nifty, geopolitical, calibration, predictions, China-Taiwan, Middle East, subcontinent triangle |
| Calibration engine | engine module in the public repository | The Python implementation of the lift-computation pipeline; includes calibrate, ephemeris, dasha, transit and overlay submodules |
| Natal chart records | tools natals folder in the public repository | JSON records for India 1947, Russia 1991, US 1776 Sibly, UK 1801, China 1949, Pakistan 1947, Iran 1979, plus a small set of principal individual charts where calibration is in progress |
| Calibrated weights | data results folder in the public repository | Per-chart, per-signature lift table; the canonical numerical output of the calibration |
| Forward-call definitions | data folder forward_calls.json | Machine-readable record of every active forward call: chart, window, observable, falsifier |
| Verification receipts | data verification folder | Per-article machine-readable receipts that capture the central call, range, falsifier and timestamp at publication |
| Architecture file | data folder architecture.json | Living inventory of what Tempora has shipped: products, content counts, infrastructure |
Every asset above is reusable under CC-BY 4.0 with attribution. The reuse can be commercial. The derivative does not have to be open. The only constraint is attribution.
Several categories of material are explicitly not covered by the license and are not published. Each has a structural reason for staying private.
Internal working papers and audit drafts. The audit cycle that ran on 9 May 2026 produced a series of working documents (cascade audit, retroactive audit, research-notes audit, calibration audit, corpus drift audit) that fed conclusions into the public surface. The working documents themselves are internal. They contain interim verdicts, hypothesis-testing notes, and the framework's ongoing internal disagreements. The conclusions feed the standards file, the recalibration plan, and the article-level reconciliations that are public; the drafts are not.
Full per-event backtest ledger. The calibration engine produces detailed scoring output on every event for every signature. The summary is the calibrated lift table, which is public. The full ledger (per-event, per-signature, per-orb, per-dasha-state breakdown) is internal because publishing the full ledger would let a competitor reverse-engineer the event selection and the scoring functions in ways that bypass the calibration discipline.
Dropped-signatures library. The current calibration uses nine signatures. A larger set was tried and dropped during development for various reasons (insufficient lift, computational instability, redundancy with other signatures). The dropped library is internal because publishing it would create surface area for misinterpretation; readers might cite a dropped signature as a published Tempora signature when the framework explicitly rejected it.
Calibration-in-progress drafts. The recalibration triggered by the May 2026 audit is producing intermediate outputs as it runs. The intermediate outputs are not public. The final recalibrated lift table will be published when the rebuild closes. Publishing intermediates would create the impression that intermediate numbers are themselves Tempora's published figures, which they are not.
Raw and processed market data. Some market datasets used in the markets-cluster backtests are licensed from third parties under terms that do not allow redistribution. Where a backtest depends on such data, the result is published but the raw input is not. A reader with independent access to the same data source can rerun the backtest.
Imprint capture data and customer data. The Kaal Imprint birth-data submissions, the briefing customer data, the email-list subscribers and the conversion analytics are private and protected. Open methodology does not extend to user data; this is the firm boundary that cannot move.
The line is structural. Methodology is open so it can be audited. User data and licensed third-party data are private because they are not Tempora's to publish. Internal working drafts are private because they are not the same surface as the published conclusions; conflating the two would create the wrong reader expectations.
The default citation format Tempora suggests for academic and research-style citations:
For a specific article, cite the article URL directly. For a quantitative claim from a forward call, prefer the machine-readable receipt in the data verification folder over prose, because the receipt is the canonical record of the central call, range, falsifier and timestamp.
For a blog post, news article, or other less formal citation, the minimum acceptable form is the firm name (Tempora Research) and a working link to the canonical article URL. The license does not require the long-form citation; it requires that the reader can identify the source.
What the license requires the reader to avoid: implying that Tempora endorses the derivative work, removing the attribution from the derivative, or claiming the methodology as one's own original framework without acknowledging Tempora as prior art. These are standard CC-BY constraints; they apply to every CC-BY work.
Researchers building on Tempora's methodology should publish their own backtests with attribution. This is not a license requirement; it is the framework's invitation. A few ways the methodology can be extended.
Calibrate a new chart. A researcher with access to a labelled event set for a chart Tempora has not calibrated (a different national chart, a corporate founding chart, an individual chart with sufficient documented event history) can use the published engine to compute a per-signature lift table. The output is comparable to the existing table. The work would constitute an extension of the framework with attribution.
Replicate at stricter thresholds. A skeptical reader can rerun the calibration with stricter event-credit requirements (require three events scoring above threshold rather than two), smaller event sets (require pre-1990 events only, removing potential modernity bias), alternative ayanamsa choices (rerun with Lahiri rather than True Pushya Paksha), or alternative house systems. The output may differ from Tempora's table; the difference is itself a research finding.
Stress-test the audit discipline. The 9 May 2026 audit found twelve event-set-depleted pairs at FAIL level. A reader can rerun the same audit on the published data and verify or contest the verdicts. If the reader's verdicts diverge, the divergence is a methodological disagreement that can be argued in public.
Build downstream products. Under CC-BY 4.0 commercial reuse, a developer can build a product that consumes the Tempora calibration output, the natal records, or the forward-call receipts. The product must attribute the source of the data; beyond that the developer is free to charge, sell or distribute as they choose.
The framework's posture is that methodology spreading is the point. The published material is bait for researchers, journalists and developers to build on. Attribution is the only return Tempora asks.
The astronomy is shared (Swiss Ephemeris). The calibration math is documented (Monte Carlo, lift ratio, threshold filter). The natal records are published. The lift table is public. None of these on their own are a competitive contribution; any astrology firm could publish the same. The contribution is the discipline of publishing all of them together with the audit gates and the failure-mode catalogue. The discipline is not licensable; it is a posture. CC-BY 4.0 covers the artifacts of the posture; the posture itself is what defines the firm.
Most astrology platforms are structurally closed. The chart-computation engine is wrapped in commercial software. The interpretive content is gated behind paywalls or app-store distribution. The underlying calibration (where any exists) is proprietary. The reader cannot verify a published forward call against source data because the source data is not published.
Tempora has chosen the opposite. The chart-computation engine sits on Swiss Ephemeris, which is open. The interpretive content is published in full on the canonical website with no paywall on the methodology articles. The calibration is documented down to the engine-module level. Forward calls carry machine-readable receipts so the call's central claim is fixed in advance and cannot be retroactively rephrased.
The trade-off is that none of the published assets are defensible as proprietary. Any competitor could clone the repository tomorrow and run the same engine on the same charts. What Tempora is betting is that the discipline of running the audit cycle, maintaining the standards file, and publishing the recalibration when figures move is structurally hard to copy; it is a posture, and a posture takes years to build. The published material is the artifact; the discipline is the firm's contribution.
Open methodology has practical limits. They are documented for the same reason the public surface is documented: a reader should know what the openness can and cannot do.
The audit is internal in execution, public at the verdict. The 9 May 2026 audit cycle ran for several days and produced multiple internal documents before the conclusions were published. A reader observing only the public surface sees the conclusions, not the deliberation. This is by design; publishing every interim document would dilute the canonical surface. A reader who wants more detail than the public surface provides is free to email and ask; what is not available is a public archive of the working drafts.
The recalibration is in flight. As of 9 May 2026, twelve calibration pairs are flagged for recalibration and the rebuild is running. Until the rebuild closes, the public lift table is read alongside the audit findings. The intermediate state is uncomfortable. A reader who wants a stable lift table would prefer to consume the post-rebuild version. The current version is the most honest one available; that is the trade-off.
The license cannot prevent misuse. CC-BY 4.0 attribution is enforceable in principle but practically rare. A reader who repackages Tempora's methodology without attribution is in violation of the license; whether the violation produces consequences depends on the practical cost of pursuing it. Tempora's posture is to invite reuse and accept that some reuse will not credit; the methodology spreading is more important than every individual case being attributed.
The user-data boundary is firm. The CC-BY license does not extend to imprint capture, briefing customer data, or email-list subscribers. A researcher who wants to study Tempora's user behaviour cannot extract that data; what they can do is read the published article on the framework Tempora applies to user charts and replicate the framework on their own data.
Astrology has a long history of closed practice. Lineage-based knowledge transmission in classical Indian Jyotish keeps technique inside teacher-student chains. Commercial astrology platforms keep computation engines proprietary. Even academic-adjacent astrology research often publishes interpretations without underlying numbers. The norms of the field run against open methodology.
Tempora's choice is to operate Vedic astrology with the publication norms of an empirically grounded research field rather than the publication norms of a divination practice. This is uncomfortable for the field; it is also the only way the framework can be audited from outside. The discomfort is the brand position: a research firm publishing under CC-BY 4.0 is structurally different from a divination service publishing under terms-of-service-only.
The invitation to other astrology operations is to consider the same posture. Open methodology is not the same as renouncing one's competitive position; the competitive position becomes the discipline rather than the data. The data is shareable; the discipline is built one audit cycle at a time.
Open licensing is a tool, not a remedy. A few things CC-BY 4.0 cannot accomplish that the brand position requires nonetheless.
It cannot make the framework infallible. The audit cycle that found twelve depleted pairs ran on the published data; the same audit could find more depletion in subsequent cycles. Open licensing makes the framework auditable; it does not make it correct.
It cannot establish credibility on its own. A published lift table under CC-BY 4.0 that no reader has verified is the same as a private lift table from the reader's perspective. Credibility comes from the cumulative record of audit cycles, recalibrations and forward-call reconciliations. The license is the precondition; the track record is the substance.
It cannot replace expert review. Researchers and practitioners with classical Vedic training will find places where the framework simplifies or operationalises a technique in ways the classical literature does not. Engagement with that critique is part of the ongoing work; CC-BY 4.0 makes the surface available for engagement, but the engagement itself is what produces refinement.
It cannot prevent reuse without attribution. The license is enforceable in principle. In practice the cost of pursuing every uncredited reuse is higher than the value of pursuing it. Tempora's posture is to accept some uncredited reuse as part of the price of openness.
The Creative Commons Attribution 4.0 International license covers Tempora's published methodology, the calibration code, the natal chart records for the six calibrated charts and Iran 1979, the calibrated lift table, the forward-call definitions, the verification receipts, all HTML articles published at tempora.ltd, and the architecture and forward-calls JSON files. Anyone can share, adapt and build commercially on this material with attribution. Full license text is at creativecommons.org/licenses/by/4.0/legalcode.
Internal working papers and audit verdicts are not public. The full per-event backtest ledger is not public. The dropped-signatures library, the calibration-in-progress drafts, raw and processed market data licensed from third parties, imprint capture data, customer data, email lists and marketing infrastructure are not public. The line is structural: the published methodology is open so it can be audited; user data and licensed third-party data are private. Tempora's research investment is in the calibration discipline and the audit gates, not in the underlying astronomy or the published numbers themselves.
For a methodology citation, use: Joshi, Shivani. Tempora Research: Calibrated Vedic Mundane Astrology Methodology and Forward Calls. Tempora Research, 2025-2026. https://tempora.ltd/. For a specific article, cite the article URL directly. For a forward-call quantitative claim, prefer the machine-readable receipt at the data verification path, which is the canonical record of the call's central claim, range, falsifier and timestamp. The receipts are versioned alongside the articles.
Yes. The CC-BY 4.0 license explicitly permits adaptation and commercial reuse with attribution. A researcher can clone the repository, install pyswisseph and the standard scientific Python stack, run python -m engine.calibrate against any of the six published natal records, and obtain the same lift figures Tempora publishes. To extend to a new chart, build a labelled event set and run the same engine. To replicate at a stricter event-credit threshold, modify the threshold and rerun. The constraint is attribution under CC-BY, not technical access.
Most astrology platforms publish interpretations rather than computations. Where computations exist, they are typically wrapped in proprietary software with closed event sets, closed weights, and no public reproduction path. Tempora publishes the engine, the natal records, the labelled event sets, the calibrated weights, the forward-call definitions, and the audit findings together. This lets any researcher verify a forward call against the source data. The trade-off is that Tempora cannot defend any of these published assets as proprietary; the contribution is the discipline of publishing them, not the assets themselves.
Yes, and Tempora actively invites it. Researchers building on the methodology should publish their own backtests with attribution to Tempora as prior art under the CC-BY 4.0 attribution requirement. Publication can be on any surface (academic preprint, blog post, peer-reviewed journal, GitHub repository) provided the attribution is visible and links to the canonical Tempora URL. What is not acceptable under the license is rebranding the methodology as one's own original framework without acknowledging the prior art. Beyond that minimum, Tempora's posture is that the methodology spreading is the point.
